EDITORIAL: Stuck in motion? Reconnecting questions and tools in movement ecology [PDF]

open access: yes, 2016
In this editorial for the Special Feature, I firstly briefly review the major milestones in tool development for movement ecology research, from the first mark–recapture techniques to the current techniques allowing users to collect high-frequency ...

Close-Kin Mark-Recapture Models [PDF]

open access: yes, 2019
Close-Kin Mark-Recapture (CKMR) is a recent extension of the ordinary mark–recapture methods used to estimate animal abundance and other population parameters. Where ordinary mark–recapture only consider the subsequent identification of the same animal a

Performance of a Deep Learning Algorithm for Melanoma Classification Across Diverse Dermoscopic and Tele‐Dermatology Datasets

open access: yesJEADV Clinical Practice, EarlyView.
ABSTRACT Background Early detection of melanoma significantly boosts patient survival rates. Deep learning has demonstrated dermatologist‐level accuracy in assessing pigmented skin lesions by analysing images at the pixel level. However, these neural networks may face challenges with ‘real‐life’ images due to limited training data and image artefacts ...

Sources of bias in applying close-kin mark-recapture to terrestrial game species with different life histories.

open access: yesEcology
Close-kin mark-recapture (CKMR) is a method analogous to traditional mark-recapture but without requiring recapture of individuals. Instead, multilocus genotypes (genetic marks) are used to identify related individuals in one or more sampling occasions ...

Bayesian Population Size Estimation With a Single Sample [PDF]

open access: yes, 2018
La stima della numerosit`a di una popolazione `e un problema comune a vari ambiti di applicazione. Le procedure di stima sono solitamente basate sul noto metodo cattura-ricattura, il quale comporta elevati costi e disturbo della popolazione.

Beyond abundance: the impact of sampling design on effective population size estimates in capercaillie

open access: yesWildlife Biology, EarlyView.
Effective population size (Ne) is a useful parameter to evaluate the long‐term viability of populations. While obtaining enough field data from wild populations to estimate Ne directly is challenging, molecular techniques applied to non‐invasive samples provide an appealing alternative.

Deep Sea – Close Kin: A Genetic Approach for Improved Fisheries Management [PDF]

open access: yes, 2015
Deep-sea fish stocks consist of species that live at depths of greater than 400 metres. While being important for EU fisheries, this natural renewable resource is particularly vulnerable to over-fishing, as many deep sea species are slow-growing and ...

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

open access: yesJournal of Animal Ecology, EarlyView.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Breeding system and reproductive skew in a highly polygynous ant population [PDF]

open access: yes, 2018
.: Factors affecting relatedness among nest members in ant colonies with high queen number are still poorly understood. In order to identify the major determinants of nest kin structure, we conducted a detailed analysis of the breeding system of the ant ...

Females tend to prefer genetically similar mates in an island population of house sparrows [PDF]

open access: yes, 2014
BACKGROUND: It is often proposed that females should select genetically dissimilar mates to maximize offspring genetic diversity and avoid inbreeding.
