The Cretaceous Kem Kem beds of Morocco and equivalent beds in Algeria have produced a rich fossil assemblage, yielding, amongst others, isolated sauropod teeth, which can be used in species diversity studies. These Albian-Cenomanian (~113 – 93.9 Ma) strata rarely...

Although amphipods are key components of the macro-fauna associated with Posidonia oceanica meadows, no studies focussed to date on the structure and diversity of such assemblages across the Mediterranean Sea. Here, we studied whether amphipod diversity reflects...

Speciation processes have long been inferred from phylogenetic, phylogeographic, and biogeographic pattern-driven perspectives. Now much current speciation research is attempting to more directly describe the underlying processes and mechanisms of divergence leading...

Random forest and similar Machine Learning techniques are already used to generate spatial predictions, but spatial location of points (geography) is often ignored in the modeling process. Spatial auto-correlation, especially if still existent in the cross-validation...

The Atlantic gray whale (Eschrichtius robustus) presents an interesting case study of climate related dispersal and local extinction. While (limited) fossil records confirm its presence in the Atlantic until the 18th century, its abundance and distribution with...
