A new rove beetle species, Edrabius uruguayensis Martínez-Villar, González-Vainer & Tomasco, sp. nov., associated with the subterranean rodent Ctenomys rionegrensis in Uruguay, is described and illustrated. Photographs, scanning electron micrographs drawings of diagnostic character states are provided. The species compared other genus. Nucleotide sequence cytochrome oxidase subunit I was reported for first time genus phylogenetic reconstruction confirms their close relationship used from...
Factors that increase reproductive variance among individuals act to reduce effective population size (Ne), which accelerates the loss of genetic diversity and decreases efficacy purifying selection. These factors include sexual cannibalism, offspring investment mating system. Pre-copulatory where female consumes male prior mating, exacerbates this effect. We performed comparative transcriptomics in two spider species, cannibalistic
Abstract Background Deceptive alternative mating tactics are commonly maintained at low frequencies within populations because males using them less competitive and acquire lower fitness than those dominant tactics. However, the successful invasion of a male deceptive tactic is plausible if deception carries no cost to females. Among gift-giving spider Paratrechalea ornata , very often offer females worthless gift, rather nutritive gift . We tested degree which gifts can occur in natural...
1. Carnivores are often food and/or macronutrient limited in their natural habitats, but whether they mostly by protein or lipid is still a matter of controversy. As many predators and carnivorous scavengers also include plant material diet (omnivory), carbohydrate limitation possible. 2. The authors used recently described double‐test procedure to test for five co‐existing species omnivorous from Uruguay (two crickets: Gryllus sp. Miogryllus verticalis ; two cockroaches: Blatta orientalis...
In the spider families Trechaleidae and Pisauridae, males offer nuptial gifts to females during courtship. Nutritive contain recently caught prey wrapped in silk, while worthless leftovers or plant parts. The presence of is known three out 16 genera (Paratrechalea Carico, 2005, Trechalea Thorell, 1869 Trechaleoides 2005) Trechaleidae, suggesting that this sexual trait widespread occurrence family. Here, we report genus Paradossenus F.O. Pickard-Cambridge, 1903. Males P. longipes...
