A focus on cranial characters for determining relatedness is a predominant trait in many datasets, however this overemphasis can lead to distortion from sampler bias. We report on revised analyses of pachycormids - a key group within Actinopterygii, as part of...

Landscapes of Fear (LOF), the spatially explicit distribution of perceived predation risk as seen by a population, is increasingly cited in ecological literature and has become a frequently used “buzz-word”. With the increase in popularity, it became necessary...

The vastness of the vertebrate fossil record and its literature makes any effort to review it in entirety a difficult task; ‘a review’ is understood to be a work that discusses the evolution and diversity of a group, drawing in knowledge on taxonomy, morphology,...

Background. Understanding constraints to the distribution of threatened species may help to ascertain whether there are other suitable sectors for reducing the risks associated with species that are recorded in only one protected locality, and to inform about the...

Body size is strongly related to physiology and ecology, and its evolution has been studied intensely for many animal groups. Crocodylomorphs occupy the intermediate–large range of body sizes among extant tetrapods, and have a rich and diverse fossil record, ranging...

The Class Bivalvia is a highly successful and ancient group including 20,000+ known species. They represent a good model for studying adaptation (anoxia/hypoxia, salinity, temperature, ...), and they are useful bioindicators for monitoring the concentration of...
