Reproductive success usually declines in the course of the season, which may be a direct
effect of breeding time, an effect of quality (individuals with high phenotypic or environmental …

Publisher Summary This chapter examines how temperature and climate change affect
reproductive performance in different species and locations. There are several ways in …

Migratory birds track seasonal resources across and between continents. We propose a
general strategy of tracking the broad seasonal abundance of resources throughout the …

Artificial light at night is a rapidly increasing phenomenon and it is presumed to have global
implications. Light at night has been associated with health problems in humans as a …

Models of Adaptive Behaviour sets out a framework for adaptive explanations of behaviour,
and applies this to give analyses of a range of biological issues such as energetic gain …

Animal Traditions maintains that the assumption that the selection of genes supplies both a
sufficient explanation of the evolution and a true description of its course is, despite its …

Summary 1 We present a multivariate model of the post‐fledging survival of juvenile great
and coal tits (Parus major L., P. ater L.) in relation to chick body condition and timing of …

(1) The aim of this paper is to estimate the shape of the curve relating first year survival to
nestling weight in individual great tits (Parus major) and to study the causality of this …

The eggs of the canary (Serinus canaria) contain variable doses of maternal testosterone.
The reported experiments investigated whether testosterone influences nestling growth and …

A seasonal decline in clutch size is typical of bird populations. This phenomenon may result
from a conflict between the advantages of early breeding (greater offspring value) and the …
