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 …

Mammalian colors and color patterns are some of the most diverse and conspicuous traits
found in nature and have been widely studied from genetic/developmental and evolutionary …

Incorrect species delimitation will lead to inappropriate conservation decisions, especially
for threatened species. The takin (Budorcas taxicolor) is a large artiodactyl endemic to the …

Pigmentation is a fundamental characteristic of living organisms that is used to absorb
radiation energy and to regulate temperature. Since darker pigments absorb more radiation …

Models for future environmental change all involve global warming, whether slow or fast.
Predicting how plants and animals will respond to such warming can be aided by using …

Melanin is the most widespread pigment in organisms. Melanin-based coloration has been
repeatedly observed to be associated with the same traits and in the same direction in …

Gloger's rule is usually interpreted as predicting darker coloured animals in warmer and
more humid/vegetated regions. The relative importance of temperature and rainfall or …

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 …

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

ABSTRACT Background and Aim Colour polymorphic populations constitute excellent
model systems for testing ecological and evolutionary hypotheses, as alternate colourations …
