A new scoring system for use in capture–recapture studies for bowhead whales photographed with drones1

open access: yesDrone Systems and Applications, 2022
Effective management of animal populations requires knowledge of life history parameters and estimates of population abundance. One method commonly used to estimate abundance is capture–recapture analyses of photographs.

Comparing Urban and Wildland Bear Densities with a DNA-Based Capture-Mark-Recapture Approach

open access: yesHuman-Wildlife Interactions, 2017
California’s black bear (Ursus americanus) population has tripled over the last 3 decades, causing an increased incidence of human–bear conflicts, many of which now occur in urban areas. Consequently, it is imperative that bear managers have the ability to monitor population parameters in both wildland and urban environments to help manage bears ...

Reinfestation of Streblidae ectoparasites (Diptera) in Carollia perspicillata (Linnaeus, 1758) (Chiroptera) Reinfestação de ectoparasitas Streblidae (Diptera) em Carollia perspicillata (Linnaeus, 1758) (Mammalia: Chiroptera)

open access: yesRevista Brasileira de Parasitologia Veterinária, 2011
The mark-recapture method allows analysis on the variation in the abundance of bat ectoparasites at consecutive captures. The objectives of this study were to compare the pattern of Streblidae parasitism between capture and recapture of C. perspicillata;

Extension of Pradel capture–recapture survival‐recruitment model accounting for transients

open access: yesMethods in Ecology and Evolution
Population growth is the sum of survival and recruitment, and knowledge of these two vital rates is crucial for understanding population dynamics. Moreover, animal populations often contain varying number of transient (i.e.

Population recovery following decline in an endangered stream-breeding frog (Mixophyes fleayi) from subtropical Australia.

open access: yesPLoS ONE, 2013
Amphibians have undergone dramatic declines and extinctions worldwide. Prominent among these have been the stream-breeding frogs in the rainforests of eastern Australia. The amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd) has been postulated

Estimating population parameters of longsnout seahorses, Hippocampus reidi (Teleostei: Syngnathidae) through mark-recapture

open access: yesNeotropical Ichthyology, 2017
Estimating population parameters is essential for understanding the ecology of species, which ultimately helps to assess their conservation status. The seahorse Hippocampus reidi is directly exposed to anthropogenic threats along the Brazilian coast, but

Age‐specific survival of reintroduced swift fox in Badlands National Park and surrounding lands

open access: yesWildlife Society Bulletin, 2016
In 2003, a reintroduction program was initiated at Badlands National Park (BNP), South Dakota, USA, with swift foxes (Vulpes velox) translocated from Colorado and Wyoming, USA, as part of a restoration effort to recover declining swift fox populations ...
