The use of camera traps to study the hooded skunk Mephitismacroura (Carnivora: Mephitidae) abundance
Caldasia, 2023 Skunks are important for the ecosystems as consumers of fruits, seeds, and insects. The hooded skunk (Mephitis macroura) is a medium-sized mammal common in North America, but its abundance is poorly known throughout its range.

ipsecr: An R package for awkward spatial capture–recapture data
Methods in Ecology and Evolution, 2023 Some capture–recapture models for population estimation cannot easily be fitted by the usual methods (maximum likelihood and Markov‐chain Monte Carlo).

A spatial capture-recapture model for territorial species [PDF]
, 2014 Advances in field techniques have lead to an increase in spatially-referenced capture-recapture data to estimate a species' population size as well as other demographic parameters and patterns of space usage.

Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale [PDF]
, 2012 Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of

A comparison of four different methods to estimate population size of Alpine marmot (Marmota marmota) [PDF]
, 2017 Obtaining reliable information on animal abundance in mountainous landscapes is challenging. Highly heterogeneous habitats tend to reduce detection probabilities, and the three-dimensional, rugged nature of the terrain poses severe limits to the ...
