Ten years of data on small mammal species in Doñana (SW Spain): 2011–2021 [PDF]

Biodiversity Data Journal
The long-term monitoring of the small mammal community in Doñana (SW Spain) was initiated in 2011 as part of the European Long-Term Ecological Research (eLTER) project, of which Doñana is a Long-Term Socio-Ecological Research (LTSER) Platform.

Towards the mother-of-all-models: customised construction of the mark-recapture likelihood function [PDF]

Animal Biodiversity and Conservation, 2004
With a proliferation of mark–recapture models and studies collecting mark–recapture data, software and analysis methods are being continually revised. We consider the construction of the likelihood for a general model that incorporates all the features ...

Citation Analysis with Mark-and-Recapture

, 2015
Mark-and-Recapture is a methodology from Population Biology to estimate the number of a species without counting every individual. This is done by multiple samplings of the species using traps and discounting the instances that were caught repeated.

Sample Sizes for Single Mark and Single Recapture Experiments [PDF]

Transactions of the American Fisheries Society, 1981
Abstract Calculation of the sample sizes necessary to attain a desired level of precision should be an important step in the design of a mark-and-recapture experiment. Equations that easily can be applied for this purpose have not been available. In this report, simple equations for calculation of the sample sizes necessary to obtain a desired degree ...

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

Ecology 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.

An evaluation of population indices for northern bobwhite

Wildlife Society Bulletin, 2019
Northern bobwhite (Colinus virginianus) populations are monitored using 2 general approaches—population indices and abundance estimators. Due to their convenient sampling designs, indices are commonly used by land managers and researchers to predict or ...

Evaluation of population densities of the common wolf spider Pardosa agrestis (Araneae: Lycosidae) in Hungarian alfalfa fields using mark-recapture

European Journal of Entomology, 2000
The absolute population density of adult Pardosa agrestis (Westring, 1862), the dominant epigeic spider species in many arable lands in Central Europe, was quantified in two alfalfa fields using a multiple mark-recapture method.

State-space modeling of multidecadal mark–recapture data reveals low adult dispersal in a nursery-dependent fish metapopulation

Canadian Journal of Fisheries and Aquatic Sciences, 2020
Quantifying connectivity within fish metapopulations is an important component in understanding population dynamics and providing an evidence base for assessment and management.

Investigating life‐history traits of Steller sea lions with multistate hidden Markov mark–recapture models: Age at weaning and body size effects

Ecology and Evolution, 2020
The duration of offspring care is critical to female fitness and population resilience by allowing flexibility in life‐history strategies in a variable environment.

Flexible and non-invasive passive integrated transponder (PIT) tagging protocols for tropical freshwater fish species

MethodsX, 2018
Passive integrated transponder (PIT) tagging has proven to be an effective mark-recapture technique for many temperate freshwater and marine fish species, but its adaptability to tropical freshwater species remains largely unknown.
