Reproductive behavior of Chavesincola inexpectabilis (Opiliones, Gonyleptidae) with description of a new and independently evolved case of paternal care in harvestmen
Abstract In this paper, we investigate the reproductive behavior of the gonyleptid Chavesincola inexpectabilis Soares & Soares 1946 (Heteropachylinae) and provide basic descriptive information aboutExpand

Mating system and exclusive postzygotic paternal care in a Neotropical harvestman (Arachnida: Opiliones)
This study tests predictions of the hypothesis of evolution of paternal care via sexual selection by using the Neotropical harvestman Pseudopucrolia sp. as the model organism. Females use naturalExpand

Egg Production Constrains Chemical Defenses in a Neotropical Arachnid
Female investment in large eggs increases the demand for fatty acids, which are allocated for yolk production. Since the biosynthetic pathway leading to fatty acids uses the same precursors used inExpand

Chemical Defense as a Condition-Dependent Trait in Harvestmen
The expression of costly traits often depends on the amount of food available to the individuals. Chemical defenses are costly, thus their production should be condition-dependent. Here, we testedExpand
