Integrating telemetry data at several scales with spatial capture–recapture to improve density estimates

open access: yesEcosphere, 2021
Accurate population estimates are essential for monitoring and managing wildlife populations. Mark–recapture sampling methods have regularly been used to estimate population parameters for rare and cryptic species, including the federally listed Mojave ...

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

Mark‐Recapture with Multiple, Non‐Invasive Marks [PDF]

open access: yesBiometrics, 2013
AbstractSummaryNon‐invasive marks, including pigmentation patterns, acquired scars, and genetic markers, are often used to identify individuals in mark‐recapture experiments. If animals in a population can be identified from multiple, non‐invasive marks then some individuals may be counted twice in the observed data.

Abundance estimation from genetic mark-recapture data when not all sites are sampled: An example with the bowhead whale

open access: yesGlobal Ecology and Conservation, 2020
Estimating abundance is one of the most fundamental and important aspects of population biology, with major implications on how the status of a population is perceived and thus on conservation and management efforts.

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.

Survival rates of adult and juvenile gyrfalcons in Iceland: estimates and drivers [PDF]

open access: yesPeerJ, 2021
Knowledge of survival rates and their potential covariation with environmental drivers, for both adults and juveniles, is paramount to forecast the population dynamics of long-lived animals.

Evaluating techniques for sampling stream crayfish (paranephrops planifrons) [PDF]

open access: yes, 1997
We evaluated several capture and analysis techniques for estimating abundance and size structure of freshwater crayfish (Paranephrops planifrons) (koura) from a forested North Island, New Zealand stream to provide a methodological basis for future ...

The Influence of Plant Dispersion on Movement Patterns of the Colorado Potato Beetle, \u3ci\u3eLeptinotarsa Decemlineata\u3c/i\u3e (Coleoptera: Chrysomelidae) [PDF]

open access: yes, 2017
The influence of plant dispersion on movements of the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae), was studied with mark-recapture techniques.

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 ...
