The Effect of Age on Survival Is Similar in Males and Females of an Aquatic Insect Species

open access: yesEcologies
Age is a critical intrinsic factor that influences the probability of survival of organisms on Earth. In many animals, the lifestyles and habitat occupancy of males and females are so different that the effect of age could be sex-dependent.

Estimación de la supervivencia anual de aves canoras migratorias bajo el efecto de una fidelidad incompleta al área de reproducción: diseños de estudios que pueden resultar de utilidad [PDF]

open access: yes
Many species of bird exhibit varying degrees of site–fidelity to the previous year’s territory or breeding area, a phenomenon we refer to as incomplete breeding site–fidelity. If the territory they occupy is located beyond the bounds of the study area or

Principios e interés de los test Bondad de Ajuste (GOF) para los modelos de captura–recaptura multiestado [PDF]

open access: yes, 2005
Optimal goodness–of–fit procedures for multistate models are new. Drawing a parallel with the corresponding single–state procedures, we present their singularities and show how the overall test can be decomposed into interpretable components.

Predicting citril finch Carduelis citrinella response to climatic change: An analysis of survival and recruitment probabilities in relation to meteorological covariates

open access: yesAnimal Biodiversity and Conservation
Understanding the impact of climate change on species’ demography is essential for assessing their vulnerability to environmental shifts. We analysed a dataset of 6,967 citril finches Carduelis citrinella captured at a Pyrenean site between 1991 and ...
