Speciation of European bullheads (Cottus spp.): The next problem for taxonomy of northern freshwater fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract High morphological and ecological diversity displayed by European bullheads led Freyhof et al. (2005) to describe 15 nominal species. However, the basis for declaring these nominal species is contentious due to a lack of rigorous statistical analysis of morphological variations among populations, limitations in the inferences made from ...

Tubule and microbranch variations in human dentine: A quantitative 3D study with serial block‐face scanning electron microscopy

open access: yesJournal of Microscopy, EarlyView.
ABSTRACT Objective: Microbranches exist within dentine, providing a network of fluid filled connections between tubules. This study used serial block‐face scanning electron microscopy to generate 3D volumes of dentine from different tooth locations, allowing for investigations of the microbranch morphology, the microbranch network characteristics and ...

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

open access: yesJournal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...
