Evaluating the efficacy of tagging adhesives for insect tracking

Agricultural and Forest Entomology, EarlyView.
Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.

A nonlinear association between chronic stress and instrumental reward learning under Pavlovian conflict: Behavioural and computational evidence

British Journal of Psychology, EarlyView.
Abstract Chronic stress, arising from prolonged exposure to unpredictable challenges, is common in everyday life and may alter cognitive processes. However, few human studies have empirically examined the association between chronic stress and reward learning, which is critical for navigating uncertain environments.

Mark–recapture studies and demography

, 2008
AbstractPopulation ecologists track wild animals over their lifetimes using mark-recapture methods. Odonates are easily marked and remain near water bodies, allowing for high recapture rates. In recent years, the focus in mark-recapture models has switched from population size estimates to survival and recapture rate estimation, and from testing ...

Loglinear Models for the Robust Design in Mark–Recapture Experiments

Biometrics, 2004
Summary.  The robust design is a method for implementing a mark–recapture experiment featuring a nested sampling structure. The first level consists of primary sampling sessions; the population experiences mortality and immigration between primary sessions so that open population models apply at this level. The second level of sampling has a short mark–

A GENERAL APPROACH TO TEMPORARY EMIGRATION IN MARK–RECAPTURE ANALYSIS

Ecology, 2002
During mark-recapture studies of open populations, animals often tempo- rarily emigrate from study areas. Such temporary emigration can cause biased estimates of survival probabilities. We present a new statistical method to estimate survival probability from the capture histories of marked individuals in the presence of temporary emigration.

A Mark-Recapture Survival Analysis

The Journal of Animal Ecology, 1982
Long-term marking studies are often used to investigate survival rates in animal populations. In many studies, a few individuals are caught regularly, whereas others may only rarely be caught.

Persistence models for mark-recapture

Environmental and Ecological Statistics, 2008
The stable of models available for analyzing mark-recapture data (Otis et al. Wild Momogr 66:135, 1978) includes those having behavioral characteristics, time variation, heterogeneity, along with combinations of those characteristics. This paper proposes use of a series of models based on the persistence model of Ramsey and Usner (Biometrics 59:331–339,

A semiparametric Bayesian approach for mark-recapture estimation

Model Assisted Statistics and Applications, 2013
This paper describes a semiparametric Bayesian approach for modelling mark-recapture data. A main assumption in modelling mark-recapture data is that survival probabilities are homogeneous. We relax this assumption by modelling survival probabilities as a function of two parameters which explain variations due to unknown biological and environmental ...

Mark-recapture models

Advances in Applied Probability, 1984
The interpretation of mark-recapture data depends on a probabilistic model for the biological system. The assumptions of the general model must be verified against what is known about the particular system. This talk considers the application of markrecapture methods to the estimation of salmon smolt migrations from Babine Lake, British Columbia.
