New distributional data on aquatic and semiaquatic bugs (Hemiptera: Heteroptera: Gerromorpha & Nepomorpha) from South America
BACKGROUND Water bugs in general play an important role in freshwater ecosystems, and knowledge about them is essential for the study of water biology and the proper management of aquatic habitats. The Neotropical fauna is relatively well known, but the existence of large under-collected areas makes taxonomic and faunistic studies concerning the aquatic and semiaquatic bugs from tropical Americ...
متن کاملChecklist of water bugs (Hemiptera: Heteroptera: Nepomorpha, Gerromorpha) of Slovakia.
The water bugs represent a significant component of the freshwater biota, play an important role in trophic webs, and may have considerable economic importance. Nevertheless, systematic research of this group has been underdeveloped in Slovakia (central Europe) for decades. This work presents a list of water bug species of Slovakia based on an exhaustive review of the literature (time span: 180...
متن کاملTrichoptera Phylogeny, Adaptations, and Biogeography Through Geologic Time
Trichoptera are a well-studied group of aquatic insects that are recognized by both entomologists and limnologists, for their especially peculiar habit of building nets and cases. The phylogeny of the order is a point of controversy with systamatists. However, the knowledge of their biogeography and their water quality and temperature tolerance provides great promise for the study of past aquat...
متن کاملSemiaquatic adaptations in a giant predatory dinosaur.
We describe adaptations for a semiaquatic lifestyle in the dinosaur Spinosaurus aegyptiacus. These adaptations include retraction of the fleshy nostrils to a position near the mid-region of the skull and an elongate neck and trunk that shift the center of body mass anterior to the knee joint. Unlike terrestrial theropods, the pelvic girdle is downsized, the hindlimbs are short, and all of the l...
متن کاملThe first assess of the haplotypes from COI gene sequences in species of spittlebugs (Cicadomorpha: Hemiptera) and aquatic true bugs (Gerromorpha and Nepomorpha: Hemiptera) in Brazil.
We made the first analysis of the COI gene sequences of 22 species of spittlebugs and aquatic true bugs sampled in São Paulo State (Brazil) and used this information to determine the variability within these groups. Considering each codon position, we observed that the third base was the most variable, and the first base was the most conserved. Among species, Mahanarva fimbriolata and Deois fla...
