Expanding the feasibility of fish and wildlife assessments with close‐kin mark–recapture

open access: yesEcosphere, 2020
Close‐kin mark–recapture (CKMR) is a powerful new method for the assessment of fish and wildlife population dynamics. Unlike traditional mark–recapture techniques, the use of kinship as an identifying mark is robust to many forms of capture heterogeneity

Recapture heterogeneity in cliff swallows: increased exposure to mist nets leads to net avoidance. [PDF]

open access: yesPLoS ONE, 2013
Ecologists often use mark-recapture to estimate demographic variables such as abundance, growth rate, or survival for samples of wild animal populations.

Bayesian mark–recapture–resight–recovery models: increasing user flexibility in the BUGS language

open access: yesEcosphere, 2021
Estimating demographic parameters of interest is a critical component of applied conservation biology and evolutionary ecology, where demographic models and demographic data have become increasingly complex over the last several decades.

A comparison of four different methods to estimate population size of Alpine marmot (Marmota marmota) [PDF]

open access: yes, 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 ...

Integrating growth and survival models for flexible estimation of size‐dependent survival in a cryptic, endangered snake

open access: yesEcology and Evolution, 2022
Estimates of demographic rates for animal populations and individuals have many applications for ecological and conservation research. In many animals, survival is size‐dependent, but estimating the form of the size–survival relationship presents ...

Estimating offspring production using capture-mark-recapture and genetic methods in red squirrels. [PDF]

open access: yes, 2010
Reproductive rate is a key demographic parameter of life history and population ecology. In traditional population-ecology studies of small mammals, this and other vital rates are inferred from capture-mark-recapture (CMR) data. However, CMR assumes that

Estimating the population structure of Javan rhinos (Rhinoceros sondaicus) in Ujung Kulon National Park using the mark- recapture method based on video and camera trap identification

open access: yesPachyderm, 2011
The population structure of the Javan rhino (Rhinoceros sondaicus) in Ujung Kulon National Park (NP) in Banten, Indonesia was assessed using visual identification and mark-recapture estimation.

Monitoring Brazilian Cavefish: Ecology and Conservation of Four Threatened Catfish of Genus Ituglanis (Siluriformes: Trichomycteridae) from Central Brazil

open access: yesDiversity, 2021
We investigated population parameters using the capture-mark-recapture method (Ituglanis passensis and I. bambui) and visual censuses (I. epikasrticus and I. ramiroi).

Home‐site fidelity and homing behavior of the big‐headed turtle Platysternon megacephalum

open access: yesEcology and Evolution, 2021
Site fidelity refers to the restriction of dispersal distance of an animal and its tendency to return to a stationary site. To our knowledge, the homing ability of freshwater turtles and their fidelity is reportedly very low in Asia.
