Wildlife Biology, EarlyView.The ruffed grouse Bonasa umbellus is a species of conservation concern that has declined across most of its range. At the southeastern trailing edge of the range in Georgia, grouse are restricted to elevations 600 m a.s.l. and abundance is relatively low.

A New Approach for Imprecise Probabilities
This paper introduces a novel concept of interval probability measures that enables the representation of imprecise probabilities, or uncertainty, in a natural and coherent manner. Within an algebra of sets, we introduce a notion of weak complementation denoted as $\psi$.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain
Wildlife Biology, EarlyView.Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Design considerations for breeding waterfowl surveys
Wildlife Society Bulletin, EarlyView.This study evaluated how different survey designs affect the accuracy and precision of breeding waterfowl population estimates in Iowa's Prairie Pothole Region. Using aerial survey data from 2016–2018, we found that conducting at least 2 visits per season reduced bias in pair estimates, particularly for wood ducks and blue‐winged teal, while mallard ...

Abundance estimates of eastern black rails in southeastern Colorado
Wildlife Society Bulletin, EarlyView.This study estimated eastern black rail (Laterallus jamaicensis jamaicensis) detection, occupancy, and abundance in southeastern Colorado. We found detection probability increased later in the season and later at night but decreased with ambient noise. Occupancy increased with residual vegetation height and detection of Virginia rail (Rallus limicola).

Integrating fecal DNA and telemetry to estimate wildlife densities in anthropogenic landscapes
Wildlife Society Bulletin, EarlyView.Density estimation is central to wildlife management efforts but can be challenging in anthropogenic landscapes due to small parcel sizes, access restrictions, and limited green space. We evaluated (a) the use of a plot‐based spatial capture‐recapture sampling design to estimate deer density in developed landscapes and (b) if integrating telemetry data

Polymorphism in Tetramethylammonium Selenocyanate – Crystal Structures of α‐, β‐, and γ‐[NMe4][SeCN]
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.This study reports the synthesis and crystallographic investigation of tetramethylammonium selenocyanate. The structures of α‐, β‐, and γ‐[NMe4][SeCN] are related to one another and also to the CsCl‐type. In the solid state, tetramethylammonium selenocyanate, [NMe4][SeCN], is polymorphic.
