Bergmann's rule states that individuals of a species/clade at higher altitudes or latitudes will
be larger than those at lower ones. A systemic review of the known literature on inter-and …

Eco-geographical rules maintained within a taxonomic clade, populations and species of
larger size were found in colder environments, and species of smaller size were found in …

Background. Large-scale patterns of body size variation have occupied biologists for over a
century, yet the causes of some of these patterns remain elusive. Bergmann's rule is a …

The science behind ecology has been contested for years, partially because of the misuse
and misrepresentation of concepts within ecology. This paper discusses the use of …

Variation in body size, growth and life history traits of ectotherms along latitudinal and
altitudinal clines is generally assumed to represent adaptation to local environmental …

Background Body size variation has played a central role in biogeographical research,
however, most studies have aimed to describe trends rather than search for underlying …

Animal body size often varies systematically along latitudinal gradients, where individuals
are either larger or smaller with varying season length. This study examines ecotypic …

Variation in body size represents one of the crucial raw materials for evolution. However, at
present, it is still being debated what is the main factor affecting body size or if the final body …

Aim We explore geographic variation in body size within the wingless grasshopper,
Phaulacridium vittatum, along a latitudinal gradient, and ask whether melanism can help …

The evolutionary and phenotypic responses to environmental gradients are often assumed
to be the same, a phenomenon known as “cogradient variation”. However, only a few insect …
