Abstract Gondwanan dinosaur faunae during the 20 Myr preceding Cretaceous–Palaeogene (K/Pg) extinction included several lineages that were absent or poorly represented in Laurasian landmasses. Among these, South American fossil record contains diverse abelisaurids, arguably most successful groups of carnivorous dinosaurs from Gondwana Cretaceous, reaching their highest diversity towards end this period. Here we describe Koleken inakayali gen. et sp. n., a new abelisaurid La Colonia Formation...
The fish clade Pelagiaria, which includes tunas as its most famous members, evolved remarkable morphological and ecological variety in a setting not generally considered conducive to diversification: the open ocean. Relationships within Pelagiaria have proven elusive due short internodes subtending major lineages suggestive of rapid early divergences. Using novel sequence dataset over 1000 ultraconserved DNA elements (UCEs) for 94 286 species (more than 70% genera), we provide...
Changes in speciation and extinction rates are key to the dynamics of clade diversification, but attempts infer them from phylogenies extant species face challenges. Methods capable synthesizing information fossil have yielded novel insights into diversification rate variation through time, little is known about their behavior when analyzing entirely extinct clades. Here, we use empirical simulated data assess how two popular methods, PyRate Fossil BAMM, perform this setting. We inferred...
Abstract The interrelationships of the three major dinosaur clades (Theropoda, Sauropodomorpha, and Ornithischia) have come under increased scrutiny following recovery conflicting phylogenies by a large new character matrix its extensively modified revision. Here, we use tools derived from recent phylogenomic studies to investigate strength causes this conflict. Using maximum likelihood as an overarching framework, examine global support for alternative hypotheses well distribution...
Assisted reproductive technologies (ART) induce vascular dysfunction and premature ageing in young apparently healthy children mice (Scherrer et al. Circulation 2012; Rexhaj JCI 2013). In adult ART mice, translates into arterial hypertension. Given the age of human population, evolution long‐term consequences induced alterations are unknown. We speculated that persist adolescents hypertension represents first clinically relevant end‐point this problem humans. We, therefore, 5 years after...
Lanchester’s laws of combat are a mathematical framework describing the relative contributions individual fighting ability and group size to overall ability. Since 1993, several studies have attempted apply this interspecific dominance relationships between nonhuman animals. However, prior work addressed only corollaries rather than themselves. Here, we directly test linear square law explain competition coral reef fish. First, analyzed relationship body find biologically accurate proxy We...
Time-calibrated phylogenies are key to macroevolutionary hypothesis testing and parameter inference, but their estimation is difficult when the number of tips large. Despite its attractive properties, joint Bayesian inference topology divergence times remains computationally prohibitive for large supermatrices. Historically, supertrees represented a popular alternative supermatrix-based phylogenetic methods, most existing supertree techniques do not accommodate branch lengths or topological...
There is abundant evidence indicating that pathological events during early life predispose to cardiovascular and metabolic diseases later in life. Recent suggests assisted reproductive technologies represent a novel important example of this problem.
