Freshwater molluscs play an important role in aquatic ecosystems, providing food for many fish species and vertebrates. Investigations on factors that determine mollusc species richness and distribution in wetland systems are scarce in the Neotropical region. The main goal of this study was to determine how much variation in mollusc richness and composition is explained by area, hydroperiod, al...

Neotropical rainforests have a very poor fossil record, making hypotheses concerning their origins difficult to evaluate. Nevertheless, some of their most important characteristics can be preserved in the fossil record: high plant diversity, dominance by a distinctive combination of angiosperm families, a preponderance of plant species with large, smooth-margined leaves, and evidence for a high...

Strix huhula Daudin, 1800 is widely distributed species of owl in the Neotropical region. However, this considered rare nature due to its dependence on forested habitat and low adaptive capacity survive anthropogenic environments. There are scattered records throughout Brazil. Here, we provide first record S. a savanna–dry forest ecotone Piauí state. This expands geographic...

Pseudogaurax Malloch is a worldwide genus of Chloropidae with 33 species in the Neotropical region and 12 occurring Brazil. The well-known for feeding habits its larvae which attack egg masses several arthropods, usually breeding sacs spiders. In this study, we expanded distribution P. cingulatus to northern Brazil recorded first time preying on Tetragnatha sacs. addition, diagnosis, digital im...

The present study is based on oribatid mite materials collected from leaf litter in two forest locations Cuba. A list of 64 species, belonging to 47 genera and 31 families, presented. Of these, one genus species are recorded for the first time Neotropical region; 17 subgenus, six genera, families Two new superfamily Oripodoidea—Lagenobates fossatus Ermilov Kontschán n. sp. (Haplozetidae) Mulier...

We report a case of male corpse colonization found inside residence in the municipality Areia, Paraíba, Brazil. The body was gaseous stage decomposition and colonized by fly larvae. reared larvae collected at crime scene on temperature-controlled. supplied beef as feeding substrate for until adult emergence to allow taxonomic identification. Three specimens Peckia (Squamatodes) ingens emerged l...

Neotropical migratory songbirds typically breed in temperate regions and then travel long distances to spend the majority of the annual cycle in tropical wintering areas. Using stable-isotope methodology, we provide quantitative evidence of dual breeding ranges for 5 species of Neotropical migrants. Each is well known to have a Neotropical winter range and a breeding range in the United States ...

The hypothesis of a Neotropical origin of the Leishmania/Endotrypanum clade is reviewed. The position of the L. (Sauroleishmania) external to the subgenus L. (Leishmania) is not consistent with the Neotropical origin of the latter subgenus. It is suggested that this may be a consequence of a faster evolutionary rate in the L. (Sauroleishmania). The implications for the classsification of the ph...
