20,25-Diazacholesterol as an Oral Contraceptive for Black-Tailed Prairie Dog Population Management

open access: yesHuman-Wildlife Interactions, 2017
Black-tailed prairie dog (Cynomys ludovicianus) colonies can become overcrowded, and the colonies, landscape, and people affected by them may benefit from controlled populations.

Pre-Historic and Recent Vicariance Events Shape Genetic Structure and Diversity in Endangered Lion-Tailed Macaque in the Western Ghats: Implications for Conservation. [PDF]

open access: yesPLoS ONE, 2015
Genetic isolation of populations is a potent force that helps shape the course of evolution. However, small populations in isolation, especially in fragmented landscapes, are known to lose genetic variability, suffer from inbreeding depression and become

An automated device for training white‐tailed deer to visual stimuli

open access: yesWildlife Society Bulletin, 2012
Although many aspects of white‐tailed deer (Odocoileus virginianus) biology and physiology have been studied thoroughly, few studies have confirmed deer cognitive perception, partly because of the difficulty of efficiently training sufficient numbers of ...

Distinguishing Log-Concavity from Heavy Tails

open access: yesRisks, 2017
Well-behaved densities are typically log-convex with heavy tails and log-concave with light ones. We discuss a benchmark for distinguishing between the two cases, based on the observation that large values of a sum X 1 + X 2 occur as result ...

Opsin genes of select treeshrews resolve ancestral character states within Scandentia [PDF]

open access: yesRoyal Society Open Science, 2019
Treeshrews are small, squirrel-like mammals in the order Scandentia, which is nested together with Primates and Dermoptera in the superordinal group Euarchonta. They are often described as living fossils, and researchers have long turned to treeshrews as
