Astronomische Konzepte und Jenseitsvorstellungen in den Pyramidentexten. The Egyptian pyramid texts were first written down around B. They are based on the religious belief in a stellar hereafter and contain the astronomical knowledge of their authors. For example, the ecliptical belt was understood as a canal, on which moon and planets cruise; of the latter Mercury, Venus and Mars were identified.
On the basis of their visibility in the course of a year the fixed stars were divided into two groups; a southern group with a period of invisibility and a northern group with continual visibility. The ecliptical "canal" was correctly identified as a division line between the two groups of fixed stars. The aim of this book is to bring these texts foreward to a better understanding of their astronomical background.

A mineral-resource survey was made of the Devils Den Roadless Area, Vermont, Geochemical sampling found traces of gold, copper, barium, lead, molybdenum, silver, tin, and thorium in rocks, stream sediments, and panned concentrates, but not in sufficient quantities to identify any resource potential.
The only apparent resources are nonmetallic commodities including abundant rock suitable for crushihg, and very small deposits of sand and gravel and marble; these also occur outside the roadless area. The area was also evaluated for bedrock uranium and thorium deposits, but not anomalously high radioactive bedrock was found. A potential may exist for oil or natural gas at great depth, but this cannot be evaluated by the present study. Denning of grizzly bears in the Yellowstone National Park area.
Radiotelemetry was used to locate grizzly bear Ursus arctos dens from to ; 35 dens were examined on the ground. Pregnant females denned in late October, and most other bears denned by mid-November. Duration of denning average , , and days for males, females, and females with new cubs, respectively. Males emerged from mid-February to late March, followed by single females and females with yearlings and 2-year-olds.
Females with new cubs emerged from early mid-April. Dens occurred on all aspects, although northerly exposures were most common. Grizzly bears usually dug new dens but occasionally used natural cavities or a den from a previous year. Males usually dug larger dens than females with young. Eight excavated and 2 natural dens of the 35 examined dens were used for more than 1 year. The mutant strain is dysregulated in cytokinesis and impaired in asexual development.
Edition of the documents. During the whole period of the Second World War, England and the USA have exchanged astronomical ephemerides with Germany, even though these data were used for the navigation of warships and aircraft and were therefore of war importance. This astonishing fact is attested by numerous documents which survived in the archives of the Astronomisches Rechen-Institut ARI. In Germany, the exchange was even explicitly authorized by the ministry which supervised the ARI i. We present here examples of ephemerides for the Sun, the Moon, planets and stars, and explain the position determination by means of astronomical data.
Ephemerides were published in almanacs which were computed and issued by special ephemeris institutes. We describe the agreements on the international exchange of ephemerides which were reached in peace times, and the continuation of this exchange during the war using intermediaries in neutral countries, first in the USA U. Involved persons were especially H. Lindblad Sweden , and A. All those relevant documents which are hold in the archives of the ARI, are described and annotated in detail.

The distribution of polar bears Ursus maritimus is circumpolar in the NOrthern Hemisphere, but known locations of maternal dens are concentrated in relatively few, widely scattered locations.
Denning is either uncommon or unknown within gaps. To understand effects of industrial development and propose increases in hunting, the temporal and spatial distribution of denning in the Beaufort Sea must be known. We caputred and radiocollared polar bears between and and determined tht denning in the Beaufort Sea region was sufficient to account for the estimated population there. Of 90 dend, 48 were on drifting pack ice, 38 on land, and 4 on land-fast ice. Mean entry and exit dates were 11 November and 5 April for land dens and 22 November and 26 March for pack-ice dens.
Female polar bears captured in the Beaufort Sea appeared to be isolated from those caught eat of Cape Bathurst in Canada. However radio-collared bears are largely faithful to substrate pack-ice, land, and land-fast ice and the general geographic area of previous dens. Bears denning on land may be vunerable to human activities such as hunting and industrial development. However, predictable denning chronology and alck of site fidelity indicate that many potential impacts on denning polar bears could be mitigated. The changing health and social care landscape, and, in particular, the financial challenges affecting the NHS, can present difficulties for staff looking for funding to support innovation and new ways of working.
One method of competitive tendering that is becoming more accepted as a way of allocating funds, encouraging staff engagement and developing innovation for research is a format based the BBC television series, Dragons' Den. This article describes how Hounslow and Richmond Community Healthcare NHS Trust, London, has developed a 'Dragons' Den initiative' of annual competitive research funding allocation to ensure that some of the most dynamic practice in the trust is captured.

Wild wolves Canis lupus that had produced pups in earlier years but were not currently pregnant, and ovariectomized captive wolves, dug dens during and after the whelping season even though they produced no pups.
These observations suggest that den digging is not a function of pregnancy or of ovarian estrogen or progesterone. We hypothesize that increasing prolactin in spring elicits or mediates den -digging behavior. A search for Denning 's resting place. The interminable scientific literature reveals William Frederick Denning as one of the great practitioners of meteor astronomy: But who was Denning?
What can we learn of his life, living and death. Glimpses of Denning the man do exist, but he is largely a man of translucency and unknowns. The journey recounted here reflects upon a recent search for Denning 's final resting place, but, once again, it is found that time and circumstance have erased virtually all of the physical history.
Identifizierung der Nitratabbauprozesse und Prognose des Nitratabbaupotenzials in den Sedimenten des Hessischen Rieds. Microbial denitrification contributes significantly to the mitigation of nitrate contamination in sedimentary aquifers by reducing nitrate coupled to the consumption of organic carbon heterotrophic and iron sulphides like pyrite autotrophic. However, these phases are often only present in trace amounts and can become depleted, so that denitrification will eventually cease.
In order to implement measures within the EC-Water Framework Directive, we investigated the denitrification potential and the denitrification processes in the sediments of the Hessian Ried. The reduction potential was quantified and characterized by solid-phase analyses of drill core samples. Depth-oriented investigations of hydrochemistry i. Despite low sulphide contents max. The results can be used to delineate risk areas, downstream of which denitrification can be expected to cease in the near future.

Endodontic, surgical and periodontal treatment of dens invaginatus. The aim of this paper is to propose a single stage global treatment of endodontic, periapical and periodontal lesions in a lateral maxillary incisor with dens invaginatus. A 24 year-old woman presenting a lateral maxillary incisor with dens invaginatus in association with periapica1 and periodontal lesions underwent simultaneous surgical, endodontic and periodontal regenerative procedures.
At 2, 6, 12, 18 months follow-up the radiographic healing appeared to be improved and the periapical lesion healed completely 1 year after surgical intervention. Surgery in association with endodontic and periodontal procedures represents the treatment of choice to maximize long term prognosis in cases of dens invaginatus with chronic periapical and periodontal lesions.

Und wie kann der Mensch beides zugleich sein? Injury biomechanics of C2 dens fractures. The objective of this study is to analyze the biomechanics of dens fractures of the second cervical vertebra in the adult population due to motor vehicle crashes. Variables such as change in velocity, impact direction and body habitus were extracted.
Results indicated that similarities exist in the two databases despite differences in sampling methods between the two sources e. Trauma is predominantly associated with the frontal mode of impact. Majority of injuries occur with change in velocities below current federal guideline thresholds. No specific bias exists with respect to variables such as age, height, weight, and gender. Because similar conclusions can be drawn with regard to vehicle model years, design changes during these years may have had little effect on this injury.
To ameliorate trauma, emphasis should be placed on the frontal impact mode and entire adult population. Because of clinical implications in the fracture type II being most critical and lack of specific coding, CIREN data demonstrates the need to improve injury coding in the AIS and application in the NASS to enhance occupant safety and treatment in the field of automotive medicine.
Franz Xaver Eder - Wanderer zwischen den Welten. Restrospektive Studie zur Analyse von klinischen Merkmalen, videodermatoskopischen Bildern, histopathologischen Diagnosen und Behandlungsergebnissen. Der Grad der Pigmentierung wurde sowohl klinisch als auch histopathologisch beurteilt. Das Muster der Pigmentierung korrelierte signifikant mit dem Alter der Patienten: Patterns of den occupation by the spotted hyaena Crocuta crocuta. Spotted hyaenas utilize isolated natal dens NDs and communal dens CDs for rearing their cubs. Here we describe patterns of natal and CD occupation by hyaenas belonging to one well-studied clan in the Maasai Mara National Reserve during a year period.
Locations of 98 den sites that were used as natal or CDs by hyaenas in the study clan were digitized in a Geographic Information System, and the duration of use of each den site, frequency of re-use, and distances involved in den moves were quantified. Hyaenas moved their CD monthly on average.
Most CD sites were occupied only once during the study, but several sites were used repeatedly. On rare occasions, the movement of hyaenas to a new den site could be attributed to a disturbance event at the CD, but factors regularly prompting hyaenas to move to new CD sites were unclear. High-ranking female hyaenas were more likely to rear their cubs from birth in a CD than low-ranking females. Low-ranking females almost always utilized isolated NDs for the first few weeks of a litter's development, and low-ranking females transferred their cubs over longer distances than did high-ranking females.
Den use by arctic foxes Alopex lagopus in a subarctic region of western Alaska. Distribution, abundance, and use of arctic fox dens located in coastal tundra communities of the Yukon—Kuskokwim delta were determined in studies from to Dens were denser and less complex than those described in studies conducted above the Arctic Circle. Eighty-three dens of varying complexity were found in the km2 study area. Nineteen dens were used by arctic foxes for whelping or rearing pups.
Three females relocated litters to multiple dens ; a maximum of four dens were used concurrently by pups from one litter. Although red foxes Vulpes vulpes were common in the region, their use of dens in the study area was minimal. Differences in vegetation at den sites and nearby unoccupied sites were minimal.
Furthermore, den sites could not be distinguished from non- den sites during aerial surveys. Denning chronology and design of effective bear management units. Reports on the effectiveness of using late fall hunting seasons to reduce the proportion of female black bears Ursus americanus in the harvest are limited, and the geographic scale over which the technique functions as intended has not been examined. During , we radio-equipped black bears in New Mexico, USA, obtained estimates of den entry and den emergence dates, and used New Mexico Department of Game and Fish harvest data to test for differences in proportion of females in the harvest relative to denning chronology.
Bears in northern New Mexico entered dens earlier and emerged later than bears in southern New Mexico P??? In northern New Mexico bears displayed the typical pattern of earlier entry and later emergence by reproductive females, proportion of females in the harvest varied over time as expected, and late fall seasons were effective P???
In contrast, denning chronology did not differ by sex in southern New Mexico, proportion of females in the harvest did not change over time, and late fall seasons were not effective P??? Manipulation of hunting season dates to influence female mortality can be an effective tool, however our study provides an example of an area where denning chronology did not differ by sex and late seasons were not effective. We also observed regional differences in timing of entrance and emergence, which suggest that scale of application may be key.
In management jurisdictions that encompass ecologically distinct areas, cover a wide range of latitudes, or are mountainous, successful use of the technique may depend on knowledge of denning chronology at multiple locations and appropriate designation of hunting unit boundaries, season dates, and data analysis units. Pyoderma fistulans sinifica, also known as fox den disease, is a rare and poorly understood inflammatory disorder of the skin and subcutaneous tissues.
This disorder is often mistaken for other inflammatory skin disorders and treated inappropriately. The authors describe the case of a year-old male who presented to the colorectal surgery service with a longstanding diagnosis of perirectal Crohn's disease. Despite aggressive immunosuppression and numerous surgical procedures, the patient continued to have unrelenting purulent drainage from the skin of his buttocks.
Following wide excision of the affected skin and subcutaneous tissues by the colorectal surgeon, the plastic surgery team reconstructed the 30 cm x 55 cm wound using a combination of local flaps and skin grafts. The initial pathology report of the excised specimen confirmed the presence of nonspecific abscesses and inflammation.
Upon special request by the plastic surgery team, the sample was resectioned with the specific intent of establishing a diagnosis of fox den disease. The additional slides met the criteria for an unequivocal diagnosis of fox den disease. Immunosuppression was discontinued and the patient healed his wounds without complication. Fox den disease is often overlooked because of the obscurity of the disease and the special histological sectioning needed to establish a diagnosis. In this case, the patient was unnecessarily treated with immunosuppressive drugs for more than 3 decades because of a misdiagnosis.
With increased awareness of fox den disease, perhaps its pathophysiology can be better elucidated as more patients are appropriately diagnosed and treated. Remote identification of polar bear maternal den habitat in northern Alaska. Polar bears Ursus maritimus give birth in dens of ice and snow to protect their altricial young. During the snow-free season, we visited 25 den sites located previously by radiotelemetry and characterized the den site physiognomy. Seven dens occurred in habitats with minimal relief. These "banks" were identifiable on aerial photographs. On aerial photos, we mapped km of bank habitats suitable for denning.
Bank habitats comprised 0. American black bear denning behavior: Observations and applications using remote photography. Researchers examining American black bear Ursus americanus denning behavior have relied primarily on den -site visitation and radiotelemetry to gather data.
Repeated den -site visits are time-intensive and may disturb denning bears, possibly causing den abandonment, whereas radiotelemetry is sufficient only to provide gross data on den emergence. We used remote cameras to examine black bear denning behavior in the Allegheny Mountains of western Virginia during March-May We deployed cameras at 10 den sites and used pictures of black bears. Adult female black bears exhibited greater extra- den activity than we expected prior to final den emergence, which occurred between April 12 and May 6, Our technique provided more accurate den -emergence estimation than previously published methodologies.
Additionally, we observed seldom-documented behaviors associated with den exits and estimated cub age at den emergence. Remote cameras can provide unique insights into denning ecology, and we describe their potential application to reproductive, survival, and behavioral research. Polar bears give birth in snow dens in midwinter and remain in dens until early spring. The survival and development of cubs is dependent on a stable environment within the maternal den.
To mitigate potential disruption of polar bear denning by existing and proposed petroleum activities, we used forward-looking infrared FLIR viewing to try to detect heat rising from dens. We flew transects over dens of radio-collared females with FLIR imager-equipped aircraft, recorded weather conditions at each observation, and noted whether the den was detected. We surveyed 23 dens on 67 occasions 1 to 7 times each. Nine dens were always detected, and 10 dens visited more than once were detected on some flights but not on others.
Four dens were never detected 17 percent , but three of those were visited only under marginal conditions. The odds of detecting a den were 4. C increase in temperature-dew point spread. The estimated probability of detecting dens in sunlight was 0. Data suggested that FLIR surveys conducted during optimal conditions for detection can produce detection rates approaching 90 percent and thus can be an important management and mitigation tool. Habitat characteristics of polar bear terrestrial maternal den sites in northern Alaska.
Polar bears Ursus maritimus give birth to and nurture their young in dens of ice and snow. During , we measured the structure of 22 dens on the coastal plain of northern Alaska after polar bear families had evacuated their dens in the spring. During the summers of and , we revisited the sites of 42 maternal and autumn exploratory dens and recorded characteristics of the under-snow habitat. The structure of polar bear snow dens was highly variable.
Others had multiple chambers and additional tunnels. Thickness of snow above and below dens was highly variable, but most dens were overlain by less than 1 m of snow. Dens were located on, or associated with, pronounced landscape features primarily coastal and river banks, but also a lake shore and an abandoned oil field gravel pad that are readily distinguished from the surrounding terrain in summer and catch snow in early winter. Although easily identified, den landforms in northern Alaska were more subtle than den habitats in many other parts of the Arctic.
The structure of polar bear dens in Alaska was strikingly similar to that of dens elsewhere and has remained largely unchanged in northern Alaska for more than 25 years. Knowledge of den structure and site characteristics will allow resource managers to identify habitats with the greatest probability of holding dens. This information may assist resource managers in preventing negative impacts of mineral exploration and extraction on polar bears. Physik gestern und heute Spurensuche.

Activity rhythms and distribution of natal dens for red foxes. The red fox, Vulpes vulpes, was investigated with snow tracking, radiotracking and directive observation at the Haibei Research Station of Alpine Meadow Ecosystem, Academia Sinica, from March to September The objectives of this study were to determine the distribution and use of natal dens , activity rhythms, and home range sizes for the foxes.
Dens of northern flying squirrels in the Pacific Northwest. Silvicultural prescriptions to enhance northern flying squirrel Glaucoinys sabrinus habitat have been suggested as an aid for recovery of the threatened northern spotted owl Strix occidentalis caurina.
Flying squirrels are hypothesized to be limited by den sites cavities in trees and by food truffles. We compared historic and contemporary black bear Ursus americanus den locations in Rocky Mountain National Park RMNP , Colorado, USA, for habitat and physiographic attributes of den sites and used maximum entropy modeling to determine which factors were most influential in predicting den -site locations.
We observed variability in the relationship between den locations and distance to trails and elevation over rime. Locations of historic den sites were most associated with slope, elevation, and covertype, whereas contemporary sites were associated with slope, distance to roads, aspect, and canopy height. Although relationships to covariates differed between historic and contemporary periods, preferred den -site characteristics consistently included steep slopes and factors associated with greater snow depth. Distribution of den locations shifted toward areas closer to human developments, indicating little negative influence of this factor on den -site selection by black bears in RMNP.
Grizzly bear denning chronology and movements in the Greater Yellowstone Ecosystem. Den entrance and emergence dates of grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem are important to management agencies that wish to minimize impacts of human activities on bears. Current estimates for grizzly bear denning events use data that were collected from — We update these estimates by including data obtained from — We used aerial telemetry data to estimate week of den entry and emergence by determining the midpoint between the last known active date and the first known date denned , as well as the last known date denned and the first known active date.
We also investigated post emergence movement patterns relative to den locations. Mean earliest and latest week of den entry and emergence were also determined. Mean week of den entry for known pregnant females was earlier than males. Earliest week of den entry for known pregnant females was earlier than other females and males. Male bears emerged from dens earlier than females. Denning period differed among classes and averaged days for females that emerged from dens with cubs, days for other females, and days for males.
Known pregnant females tended to den at higher elevations and, following emergence, remained at higher elevation until late May. Females with cubs remained relatively close den sites until the last 2 weeks in May. Timing of denning events was similar to previous estimates for this and other grizzly bear populations in the southern Rocky.
Vegetative characteristics of swift fox denning and foraging sites in southwestern South Dakota. Vegetative characteristics of swift fox Vulpes velox denning and foraging habitats were studied in southwestern South Dakota. We followed 14 radio-collared foxes over a two-year period and identified 17 den sites and 82 foraging sites. Height-density of vegetation visual obstruction reading, VOR was determined on each den and foraging site and on Den use and selection by northern flying squirrels in fragmented landscapes.
We studied den use and den -habitat selection by the Prince of Wales Island flying squirrel Glaucomys sabrinus griseifrons at multiple spatial scales in fragmented temperate rain-forest habitats because of the role dens play in the distribution, reproduction, and population density of this endemic subspecies.

A female black bear denning habitat model using a geographic information system. We used the Mahalanobis distance statistic and a raster geographic information system GIS to model potential black bear Ursus americanus denning habitat in the Ouachita Mountains of Arkansas. The Mahalanobis distance statistic was used to represent the standard squared distance between sample variates in the GIS database forest cover type, elevation, slope, aspect, distance to streams, distance to roads, and forest cover richness and variates at known bear dens.
Two models were developed: Differences between habitat at den sites and habitat across the study area were represented in 2 new GIS themes as Mahalanobis distance values. Cells similar to the mean vector derived from the known dens had low Mahalanobis distance values, and dissimilar cells had high values.
The reliability of the predictive model was tested by overlaying den locations collected subsequent to original model development on the resultant den habitat themes. Although the generalized model demonstrated poor reliability, the model specific to rock dens had good reliability. Bears were more likely to choose rock den locations with low Mahalanobis distance values and less likely to choose those with high values. The model can be used to plan the timing and extent of management actions e.
Raccoon Procyon lotor diurnal den use within an intensively managed forest in central West Virginia. As part of a Raccoon ecology study on an industrial forest in the Allegheny Mountains of central West Virginia, we radio-tracked 32 Raccoons to diurnal den sites to determine relative use of dens that included cavity trees, rock dens , log piles, slash piles, and exposed limbs. Patterns of den use significantly differed between sexes and among seasons. Overall, we recorded 58 cavity dens in 12 tree species with 7 maternal dens found in 5 tree species. Raccoons selected larger-diameter den trees than available cavity trees and non-cavity trees.
Because the abundance of suitable tree cavities is known to influence Raccoon densities and recruitment at fine spatial scales and female Raccoons in this study used tree cavities as maternal den sites, the continued harvest of large-diameter trees i. Selection of den sites by black bears in the southern Appalachians. We evaluated selection of den sites by American black bears Ursus americanus in the Pisgah Bear Sanctuary, western North Carolina, by comparing characteristics of dens at 53 den sites with availability of habitat characteristics in annual home ranges of bears and in the study area.
We also tested whether den -site selection differed by sex, age, and reproductive status of bears. In addition, we evaluated whether the den component of an existing habitat model for black bears predicted where bears would select den sites. We found bears selected den sites far from gravel roads, on steep slopes, and at high elevations relative to what was available in both annual home ranges and in the study area. Den -site selection did not differ by sex or age, but it differed by reproductive status. Adult females with cubs preferred to den in areas that were relatively far from gravel roads, but adult females without cubs did not.
The habitat model overestimated the value of areas near gravel roads, underestimated the value of moderately steep areas, and did not include elevation as a predictor variable. Our results highlight the importance of evaluating den selection in terms of both use and availability of den characteristics. Nichtinterventionelle Studie bei erwachsenen Patientinnen mit leichter bis mittelschwerer Akne.
Im Gesamtkollektiv wurden vier Melanome diagnostiziert, davon zwei zerebrale Melanome im Kindesalter, ein kutanes Melanom im Erwachsenenalter und eines, das sich als proliferierender Knoten erwies. Bei vier Kindern wurde eine neurokutane Melanozytose festgestellt, drei davon mit neurologischer Symptomatik. In Germany and the Netherlands spatial information about the social structure of the inhabitants is used for the coordination of financial and human resources in the local school-system.
The aim is to reduce educational inequalities by taking the social context of the schools into account. The article explains two approaches. In North Rhine-Westphalia Germany a so called Sozialindex is used to distribute additional teachers to municipalities with difficult social surroundings. The Dutch government uses an instrument to give each pupil a weight gewichtenregeling depending on the specific educational background. Combined with an evaluation of the school location an additional budget, if necessary, will be payed.
It has been common practice for decades, especially since the Convention on Biological Diversity was adopted in Rio , to protect certain marine areas, and the possibilities and scope of such marine protection measures have been widely discussed. The Helsinki and Oslo-Paris Conventions for the protection of the marine environment, which are relevant for Germany, provide a framework for the establishment of marine protected areas.
More protected areas are being added to the system. Information on the current status of both marine environmental protection systems is provided in this paper. Gedanken und Experimente nach Einstein, Podolsky und Rosen. Physikalische Systeme sind im Prinzip separierbar.
Ja mei: Wie ich lernte, die Ehe zu schließen (Jungjournalist Sebastian 2) (German Edition)
Diese erweisen einmal mehr die Quantenmechanik als richtige Theorie. Thoughts and Experiments after Einstein, Podolsky and RosenSince the advent of quantum mechanics there have been attempts of its interpretation in terms of statistical theory concerning individual classical systems.
The very conditions necessary to consider hidden variable theories describing these individual systems as classical had been pointed out by Einstein, Podolsky and Rosen in Physical systems are in principle separable. If it is possible to. Landward and eastward shift of Alaskan polar bear denning associated with recent sea ice changes. We evaluated changes in the distribution of polar bear maternal dens between and , using satellite telemetry. We evaluated whether hunting, attraction to bowhead whale remains, or changes in sea ice could explain changes in den distribution.
We concluded that denning distribution changed in response to reductions in stable old ice, increases in unconsolidated ice, and lengthening of the melt season. In consort, these changes have likely reduced the availability and quality of pack ice denning habitat. Further declines in sea ice availability are predicted. Therefore, we expect the proportion of polar bears denning in coastal areas will continue to increase, until such time as the autumn ice retreats far enough from shore that it precludes offshore pregnant females from reaching the Alaska coast in advance of denning.
However, both the public and the potentially affected labour force often adopt sceptical, and sometimes even hostile attitudes towards investors from these countries. This article shows that apart from a few exceptions investors from the BRIC countries are generally better than their reputation precedes. An important conclusion drawn in this paper is that investors should not be received with stereotypes. Rather, it is necessary to perform deeper investigations into their strategies and the specific investment goals in each case.
This is all the more necessary to ensure that investments from BRIC countries do not conflict with the domestic firms' interests or of their personnel. In fact, they can assist to increase the competitiveness of German firms, and as such not only prove beneficial for the workforce but also for Germany as a business destination. Ein Blick ins Licht.

During 40 sessions spanning h, we observed 8 adults and 14 dependent cubs outside dens for Following initial den breakout, polar bears remained at their den sites for 1. The average length of stay in dens between emergent periods was significantly shorter in 1. While outside, adult bears were inactive We found no significant relationships between den emergence activity and weather. Results for these bears were within the range of findings in other studies of denned polar bears.
Den site activity patterns of adult male and female swift foxes, Vulpes velox, in Northwestern Texas. Activity of Swift Foxes Vulpes velox at den sites was studied in northwestern Texas during pup rearing seasons in and to determine role of males in parental care. Twenty-four percent of radio-collared females with a potential to breed successfully raised pups to eight weeks of age.
We intensively monitored presence and absence of male and female Swift Foxes at two den sites each year. Female and male Swift Foxes largely stayed at dens during diurnal hours and were active away from dens during nocturnal and crepuscular hours. Females and males spent Decrease in time spent at the den by the female following loss of her mate suggested that loss of one parent might severely impact recruitment of Swift Foxes. Our observations indicated that intense Coyote Canis latrans depredation may severely impact pup-rearing success as well as the parental care within Swift Fox family groups.
Habitat characteristics at den sites of the Point Arena mountain beaver Aplodontia rufa nigra. The Point Arena mountain beaver Aplodontia rufa nigra is a federally listed endangered species, but has been the subject of few studies. Mountain beavers use burrows that include a single subterranean den. Foremost among the information needs for this subspecies is a description of the above-ground habitat features associated with dens. Polar bears Ursus maritimus give birth during mid-winter in dens of ice and snow.
Denning polar bears subjected to human disturbances may abandon dens before their altricial young can survive the rigors of the Arctic winter. Because the Arctic coastal plain of Alaska is an area of high petroleum potential and contains existing and planned oil field developments, the distribution of polar bear dens on the plain is of interest to land managers. Such habitats were distributed uniformly and comprised 0. Ground-truth sampling suggested that we had correctly identified Knowledge of the distribution of these habitats will help facilitate informed management of human activities and minimize disruption of polar bears in maternal dens.
Glaucomys sabrinus coloratus Carolina Northern Flying Squirrel is a federally endangered subspecies that occurs in high elevation forests of the southern Appalachian Mountains. Denning sites may be a limiting factor for this subspecies in areas where cavity trees are not abundant or where interspecific competition from other tree squirrels occurs. This shortage can result in use of unusual denning sites, such as subterranean dens.
