Diversification events and the effects of mass extinctions on Crocodyliformes evolutionary history
The rich fossil record of Crocodyliformes shows a much greater diversity in the past than today in terms of morphological disparity and occupation of niches. We conducted topology-based analyses seeking diversification ...
Shared Escovopsis parasites between leaf cutting and non leaf cutting ants in the higher attine fungus growing ant symbiosis
Fungus-gardening (attine) ants grow fungus for food in protected gardens, which contain beneficial, auxiliary microbes, but also microbes harmful to gardens. Among these potentially pathogenic microorganisms, the most ...
Phylogenetic tests reject Emery’s rule in the evolution of social parasitism in yellowjackets and hornets
Social parasites exploit the brood-care behaviour and social structure of one or more host species. Within the social Hymenoptera there are different types of social parasitism. In its extreme form, species of obligate ...
Temporal and phylogenetic evolution of the sauropod dinosaur body plan
The colossal size and body plan of sauropod dinosaurs are unparalleled in terrestrial vertebrates. However, to date, there have been only limited attempts to examine temporal and phylogenetic patterns in the sauropod ...
The relationships of the Euparkeriidae and the rise of Archosauria
For the first time, a phylogenetic analysis including all putative euparkeriid taxa is conducted, using a large data matrix analysed with maximum parsimony and Bayesian analysis. Using parsimony, the putative euparkeriidDorosuchus ...
