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

First Vasectomy Procedure Successfully Performed on a Southern African Male Giraffe (Giraffa camelopardalis giraffa)

Zoo Biology, EarlyView.
First successful vasectomy in a southern African male giraffe, Giraffa camelopardis giraffa ABSTRACT This study reports the first successful vasectomy on a southern African male giraffe (Giraffa camelopardalis giraffa). The goal of the procedure was to create a teaser male for reproductive studies.

Modeling and Mapping Coyote (Canis latrans) Abundance in Northwestern Vermont [PDF]

, 2018
Predators such as, coyotes (Canis latrans), have profound effects on ecosystems. Coyotes are recent arrivals in the northeastern United States of America, and in Vermont their ecology remains poorly understood.

A multi‐trait evaluation of patterns and fitness consequences of breeding phenology plasticity with nocturnal warming and food restriction in a lizard

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Faced with climate warming, ectothermic species shift their breeding phenology, which is in part attributed to an acceleration of gestation or incubation in warmer environments.

Modelos jerárquicos de marcaje–recaptura: un marco para la inferencia de procesos demográficos [PDF]

, 2004
The development of sophisticated mark–recapture models over the last four decades has provided fundamental tools for the study of wildlife populations, allowing reliable inference about population sizes and demographic rates based on clearly formulated ...

Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

When do beetles and bugs fly? A unified scheme for describing seasonal flight behaviour of highly dispersing primary aquatic insects [PDF]

, 2013
Many authors investigated the dispersal flight of aquatic insects, but the exact length of the seasonal flying periods and its main characteristics have not been determined.

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

Journal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.
