Functional changes in web design along the ontogeny of two orb-weavers
Orb webs evolved primarily to capture prey, though they also have other functions. Recently, it has been argued that the orb web does not work as a functional unit, but instead some sections or components have presumably ...
Static allometry and sexual size dimorphism in Centruroides margaritatus (Scorpiones: Buthidae)
Abstract. Animal body traits are scaled relative to overall body size depending on the evolutionary context. Most naturally selected traits are scaled approximately isometrically (constitute a constant proportion of the ...
Sexual size dimorphism and acoustical features of the pre-advertisement and advertisement calls of Rhinophrynus dorsalis Duméril & Bibron, 1841 (Anura: Rhinophrynidae)
Las interacciones entre selección natural, selección sexual, y los requerimientos ecológicos específicos de las especies son responsables de la evolución de comportamientos complejos de cortejo y estrategias reproductivas. ...
Loss of cheliceral clasping in Leucauge sp. (Araneae, Tetragnathidae)
In male spiders, genitalia, sexual behaviour and secondary sex morphology tend to diverge rapidly across species, presumably as a result of sexual selection. In the three Leucauge species for which pre- and copulatory ...
Variation and possible function of egg sac coloration in spiders
Coloration of the egg sacs of spiders varies widely to the human eye, both across and within taxonomic groups. These differences in coloration are expected with differences in the biology and ecology of different species. ...
