Stabilized morphological evolution of spiders despite mosaic changes in foraging ecology

Jonas Wolff, Kaja Wierucka, Jonathan Coddington, Gustavo Hormiga, Michael Kelly, Marie Herberstein, Martín Ramírez & Gustavo Paterno
A prominent question in animal research is how the evolution of morphology and ecology interact in the generation of phenotypic diversity. Spiders are some of the most abundant arthropod predators in terrestrial ecosystems and exhibit a diversity of foraging styles. It remains unclear how spider body size and proportions relate to foraging style, and if the use of webs as prey capture devices correlates with changes in body characteristics. Here we present the most extensive...

Data for: Sexual dichromatism may not be a good index of sexual or natural selection in the blue cardinalids (Aves: Passeriformes).

Natalia C. García, Ana S. Barreira & Pablo L. Tubaro
More than a century ago, Darwin and Wallace started a still ongoing debate over which are the predominant forces driving sexual dichromatism (i.e., differences in body coloration between males and females): is it sexual selection on males to become more attractive, or is it natural selection on females to become more cryptic? While these are not mutually exclusive, the degree of sexual dichromatism has been extensively used as a proxy of the intensity of one...
