Type localities—the places of origin of the name-bearing type specimens of species and subspecies—are crucial for taxonomic identification and for maintaining taxonomic and nomenclatural stability. However, historica...

Hemocyanin (Hc), a copper-containing extracellular multimeric protein, is the major protein component of hemolymph in different arachnid groups. Hc possesses 7 or 8 very well-characterized types of monomers with molecula...

Sexual dimorphism and trait allometry provide a framework to explore the potential selective pressures shaping morphological evolution. We analyzed two camel spider species with contrasting mating tactics: Titanopuga sal...

The Limarí valley, located in the Coquimbo Region of Chile, is an important agricultural area that is immersed in the transverse valleys of the Norte Chico. In recent decades, the continuous expansion of agriculture tow...

The atypoid mygalomorphs include spiders from three described families that build a diverse array of entrance web constructs, including funnel-and-sheet webs, purse webs, trapdoors, turrets and silken collars. Molecular ...

The development of Pardosa saltans wolf spiders inside an egg sac includes two periods: an embryonic period and a post-embryonic period after hatching. We investigated spiderlings’ energy expenditure to assess energeti...

Sexual conflict may influence the shape and evolution of body structures that males use to grasp females during mating. Not only sexual coercion but also intersexual cooperation may be involved during clasping behavior. ...

Lipids due to its hydrophobic nature are transported in the hemolymph mainly by lipoproteic fractions. In the present work we studied the lipoproteic fractions present in the hemolymph of the spider Grammostola rosea. Th...

Los artrópodos son esenciales para los ecosistemas áridos. Su principal amenaza es la pérdida de hábitat. Es valioso analizar su dinámica espacial en función de factores ambientales porque permiten predecir cambios...
