Just a matter of size? Evaluating allometry and intersexual heterometry in Pagurus bernhardus using ratios and indices (Decapoda, Anomura)

open access: yesIntegrative Zoology, Volume 19, Issue 5, Page 807-823, September 2024.
We analyzed 190 specimens of the common European hermit crab species Pagurus bernhardus to look for the heterometry between the sexes regardless of the body size. We calculated three different indices and found all to be significantly different between males and females, indicating that males have bigger major and minor chelipeds than females, even if ...

A novel gene rearrangement in the mitochondrial genome of Coenobita brevimanus (Anomura: Coenobitidae) and phylogenetic implications for Anomura [PDF]

open access: yes, 2019
Abstract Background: Gene arrangement in vertebrate mitochondrial genomes (mitogenomes) is relatively conserved and fewer gene arrangement is discovered. In contrast, that in invertebrate mitogenomes is relatively common. Although a gradually growing number of gene rearrangement in hermit crabs (Paguridae) has been discovered, it is surprising ...
