Metric and non-metric guides for the determination between fore- and hindlimb phalanges of Rangifer tarandus

open access: yesRangifer, 2019
Phalanges are a great untapped resource in the zooarchaeology of Rangifer tarandus. The utilization of this resource, however, is constrained by a current inability to consistently differentiate fore- from hindlimb phalanges in a mixed assemblage.

Effect of testosterone on antler growth in yearling male reindeer

open access: yesRangifer, 1983
1. The effect of exogenous testosterone on ander growth in yearling male reindeer (Rangifer tarandus tarandus) was tested. 2. Testosterone (33 mg/kg) inhibited antler growth, and in one animal induced cleaning and subsequent casting of the antlers.

New insights into the microbiota of the Svalbard reindeer Rangifer tarandus platyrhynchus

open access: yesFrontiers in Microbiology, 2016
Svalbard reindeer (Rangifer tarandus platyrhynchus) is a non-migratory subspecies of reindeer inhabiting the high-arctic archipelago of Svalbard. In contrast to other Rangifer tarandus subspecies, Svalbard reindeer graze exclusively on natural sources of

Abnormal testes in reindeer, Rangifer tarandus [PDF]

open access: yesReproduction, 1979
Summary. In a sample of reindeer from South Georgia, 4 males were abnormal in that 1 had bilateral cryptorchid testes, 2 each had 1 cryptorchid testis and 1 had a vestigial testis. The antlers of the cryptorchid males were small, but the antler cycle itself was hardly affected.

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Behavioral responses of black bears to human presence and infrastructure in Yosemite National Park

open access: yesThe Journal of Wildlife Management, EarlyView.
Using GPS collar data from black bears in Yosemite National Park, we examined how bear spatiotemporal activity in relation to human development shifted during the COVID‐19 park closure in 2020. In the absence of visitors, bears maintained consistent landscape‐scale space use but altered fine‐scale spatial and temporal behaviors.

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

open access: yesOikos, EarlyView.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.
