Glucocorticoids link forest type to local abundance in tropical birds

Simone Messina, David Edwards, Valeria Marasco, Virginie Canoine, Cindy Cosset, Suzanne Tomassi, Suzan Benedick, Marcel Eens & David Costantini
Selective logging is a major driver of environmental changes in the tropics. Recently, there has been increasing interest in understanding which traits make bird species resilient or vulnerable to such changes. Physiological stress mediated by the steroid hormone corticosterone (CORT) might underlie changes in local abundance of species because it regulates a range of body functions and behaviours to maintain homeostasis in changing environments. We conducted a three-year study to assess: (i) the variation in...

Data from: Proximate and ultimate drivers of variation in bite force in the insular lizards Podarcis melisellensis and Podarcis sicula

Bite force is a key performance trait in lizards since biting is involved in many ecologically relevant tasks, including foraging, fighting, and mating. Several factors have been previously suggested to impact bite force in lizards, such as head morphology (proximate factors), or diet, intraspecific competition, and habitat characteristics (ultimate factors). However, these have been generally investigated separately and mostly at the interspecific level. We tested which factors drive variation in bite force at the population...

Data from: Ostracods from the end-Permian mass extinction in the Aras Valley section (Northwest Iran)

Jana Gliwa, Marie-Béatrice Forel, Sylvie Crasquin, Abbas Ghaderi & Dieter Korn
The Aras Valley section (NW Iran) exposes a sedimentary succession that allows to study ostracod diversity patterns during/across the end-Permian mass extinction because of its ubiquitous fossil record. For the present study, 59 samples were investigated for their ostracod abundances, which ranged from 4 to 31500 specimens per 500 g. In 45 sample horizons, the ostracods were identified to the species-level. In total, 3,425 specimens were determined and 62 species were identified, of which one...

Data from: Hurricane effects on Neotropical lizards span geographic and phylogenetic scales

Extreme climate events such as droughts, cold snaps, and hurricanes can be powerful agents of natural selection, producing acute selective pressures very different from the everyday pressures acting on organisms. However, it remains unknown whether these infrequent but severe disruptions are quickly erased by quotidian selective forces, or whether they have the potential to durably shape biodiversity patterns across regions and clades. Here, we show that hurricanes have enduring evolutionary impacts on the morphology of...

Data from: Ups and downs of belemnite diversity in the Early Jurassic of Western Tethys

Pascal Neige, Pascal Neige, Robert Weis & Emmanuel Fara
Although belemnites form a major clade of extinct cephalopods, the early stage of their diversification remains poorly known in time and space. Here we investigate the first diversification episodes of belemnites (order Belemnitida) using a new species-level database encompassing the Hettangian-Aalenian interval (Early Jurassic-earliest Middle Jurassic) and covering the Western Tethys. Rarefied richness shows a four-fold increase from the Planorbis chronozone to the Ibex chronozone, a strong decrease between the Margaritatus and Spinatum chronozones, followed...

Phylogenomics of scorpions reveal a co-diversification of scorpion mammalian predators and mammal-specific sodium channel toxins

Carlos Santibanez, Shlomi Aharon, Jesús Ballesteros, Guilherme Gainett, Caitlin Baker, Edmundo González-Santillán, Mark Harvey, Mohamed Hassans, Ali Abu-Almaaty, Shorouk Aldeyarbi, Lionel Monod, Andrés Ojanguren-Affilastro, Robert Raven, Ricardo Pinto Da Rocha, Yoram Zvik, Efrat Gavish-Regev & Prashant Sharma
Scorpions constitute a charismatic lineage of arthropods and comprise more than 2,500 described species. Found throughout various tropical and temperate habitats, these predatory arachnids have a long evolutionary history, with a fossil record that began in the Silurian. While all scorpions are venomous, the asymmetrically diverse family Buthidae harbors nearly half the diversity of extant scorpions, and all but one of the 58 species that are medically significant to humans. Many aspects of scorpion evolutionary...

Morpho butterflies eyespot data

Vincent Debat
This data set contains (1) the presence absence data of each eyespot at each of the different putative locations (eyespot_nb.txt); (2) the coordinates of the 4 landmarks used to assess eyespot positions plus landmarks depicting wing shape for wing shape/eyespot covariation (Moyen-post-final.txt); (3) the coordinates of the semilandmarks and landmarks used to assess eyespot shape variation (Ocelles-contour-final BE.txt).

Maternal and genetic correlations between morphology and physical performance traits in a small captive primate, Microcebus murinus

Pauline Zablocki-Thomas, Simon Lailvaux, Fabienne Aujard, Emmanuelle Pouydebat & Anthony Herrel
Physical performance traits are key components of fitness and direct targets of selection. Maternal effects are important components of integrated phenotypes in a variety of species. Yet their contribution to variation in performance, and phenotypes closely associated with performance, remains poorly understood. We used an animal model approach to quantify the contribution of maternal effects to performance trait variation (in bite force and pull strength) and the relationships between performance and the relevant underlying morphology...

Phenotypic integration in feliform carnivores: covariation patterns and disparity in hypercarnivores versus generalists

Margot Michaud
The skeleton is a complex arrangement of anatomical structures that covary to various degrees depending on both intrinsic and extrinsic factors. Among the Feliformia, many species are characterized by predator lifestyles providing a unique opportunity to investigate the impact of highly specialised hypercarnivorous diet on phenotypic integration and shape diversity. To do so, we compared the shape of the skull, mandible, humerus, and femur of species in relation to their feeding strategies (hypercarnivorous versus generalist...
