Morphological allometry refers to patterns of covariance between body parts resulting from
variation in body size. Whether measured during growth (ontogenetic allometry), among …

The frequency and severity of droughts in certain areas is increasing as a consequence of
climate change. The associated environmental challenges, including high temperatures, low …

Within-population variation in ageing remains poorly understood. In males, condition-
dependent investment in secondary sexual traits may incur costs that limit ability to invest in …

Sexually selected traits are often highly variable in size within populations due to their close
link with the physical condition of individuals. Nutrition has a large impact on physical …

Although the ecological and evolutionary importance of environmentally induced parental
effects is now widely recognized, such effects are still typically studied by contrasting just two …

Abstract Theory predicts that the plastic expression of sex-traits should be modulated not
only by their production costs but also by the benefits derived from the presence of rivals and …

We use allometric analysis to explore how acoustic signals scale on individual body size
and to test hypotheses about the factors sha** relationships between signals and body …

In the present investigation, effects of organic acids and probiotics on growth of Apis
mellifera workers were studied under different experimental conditions. Significant weight …

Many studies have attempted to account for variation in male reproductive success by
quantifying a single trait such as an ornament or a behavior, but male reproductive …
