Abstract The Japanese rhinoceros beetle Trypoxylus dichotomus is one of the largest beetle
species in the world and is commonly used in traditional Chinese medicine. Ten subspecies …

Habitat loss and habitat fragmentation usually occur together, at the same time and place.
However, while there is a consensus that habitat loss is the preeminent threat to biodiversity …

Many species show a diverse range of sizes; for example, domestic dogs have large
variation in body mass. Yet, the internal structure of the organism remains similar, ie, the …

1. The energy available for reproduction is usually limited by resource acquisition (ie
condition). Because condition is known to be strongly affected by environmental factors …

Dung beetle functional ecology has traditionally focused on studying the relation between
traits and ecosystem functions in multispecies assemblages, often ignoring the contribution …

Many species have evolved alternate phenotypes, thus enabling individuals to conditionally
produce phenotypes that are favorable for reproductive success. Examples of this …

Gene duplication provides an essential source of novel genetic material to facilitate rapid
morphological evolution. Traits involved in reproduction and sexual dimorphism represent …

Size and shape constitute fundamental aspects in the description of morphology. Yet while
the developmental-genetic underpinnings of trait size, in particular with regard to scaling …

We revise the genus Conostigmus Dahlbom 1858 occurring in Madagascar, based on data
from more specimens than were examined for the latest world revision of the genus. Our …

I used linear and nonlinear regression to re-examine the allometric relationship between
length of the cephalic horn and width of the pronotum (a measure of body size) for males of …
