Temporal and spatial variations of gyne production in the ant Formica exsecta [PDF]

, 2003
Social insects have become a general model for tests of sex allocation theory. However, despite tremendous interest in the topic, we still know remarkably little about the factors that cause dramatic differences in sex allocation among local populations.

Nearly unbiased estimator of contemporary Ne/N based on kinship relationships

Ecology and Evolution, 2020
This study develops a nearly unbiased estimator of the ratio of the contemporary effective mother size to the census size in a population, as a proxy of the ratio of contemporary effective size (or effective breeding size) to census size (Ne/N or Nb/N ...

Using spatial genetics to quantify mosquito dispersal for control programs

BMC Biology, 2020
Background Hundreds of millions of people get a mosquito-borne disease every year and nearly one million die. Transmission of these infections is primarily tackled through the control of mosquito vectors. The accurate quantification of mosquito dispersal

Close-Kin Mark-Recapture Models [PDF]

, 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

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

, 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 ...

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Estimating effective population size using close‐kin mark–recapture

Methods in Ecology and Evolution
Close‐kin mark–recapture (CKMR) is a method that allows estimating population census size, among other parameters, through the observed number of pairs that are close‐kin including parent–offspring pairs (POPs) and half‐sibling pairs (HSPs).

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

Wildlife 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.

Bayesian Population Size Estimation With a Single Sample [PDF]

, 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.

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

Journal 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.
