Gloger's rule is an ecogeographical rule that links animal colouration with climatic variation.
This rule is named after CWL Gloger who was one of the first to summarise the associations …

Biological rules describe general morphological, structural and genetic patterns within and
across species. Within these, ecogeographical rules correlate phenotypic variation of …

Ecogeographical rules that associate climate with organismal form and function can reveal
patterns of climatic adaptation. Two rules link animal coloration with climate: Gloger's rule …

The strength of biotic interactions is generally thought to increase toward the equator, but
support for this hypothesis is contradictory. We explored whether predator attacks on …

Convergent evolution is widely regarded as a signature of adaptation. However, testing the
adaptive consequences of convergent phenotypes is challenging, making it difficult to …

Aim In wide‐ranging taxa occupying broad climate gradients, alternative colour pattern
variants (ie morphs) may emerge as an adaptive response to local climatic regimes. We …

An animal's environment contains many risks causing animals to scan their environment for
potential predators and threats from conspecifics. How much time they invest in such …

Climatic gradients frequently predict large‐scale ecogeographical patterns in animal
coloration, but the underlying causes are often difficult to disentangle. We examined …

Butterflies are among the most colourful organisms in the world and colour plays a central
role in many of their life-history strategies. However, the efficacy of coloration strategies in …

Color lightness of insects is an important ecological trait affecting their performance through
multiple functions such as thermoregulation, UV protection and disease resistance. The …
