In the present study, the first cytogenetic data was obtained for the ant species Strumigenys louisianae, from a genus possessing no previous cytogenetic data for the Neotropical region. The chromosome number observed was 2n = 4, all possessing metacentric morphology. Blocks rich in GC base pairs were observed in the interstitial region of the short arm of the largest chromosome pair, which may...

To elucidate chloroplast genome evolution within neotropical-paleotropical bamboos, we fully characterized the chloroplast genome of the woody bamboo Guadua angustifolia. This genome is 135,331 bp long and comprises of an 82,839-bp large single-copy (LSC) region, a 12,898-bp small single-copy (SSC) region, and a pair of 19,797-bp inverted repeats (IRs). Comparative analyses revealed marked cons...

There are three species of Neotropical cats whose northernmost distribution reaches the USA-Mexico border region: the jaguar Panthera onca, ocelot Leopardus pardalis and jaguarundi Herpailurus yagouaroundi. To ensure the long-term viability of Neotropical cat populations in this region it is imperative to identify current distribution and status in the northern limits of their range to conserve...

BACKGROUND Members of the family Mycetophilidae (Diptera) have life cycles that are typically associated with fungus. Their biology is relatively well known in the Palaearctic, though other regions are poorly known, and there are no associations recorded between mycetophilid immatures and fungi in the Neotropical region. Here we report the first association between a mycetophilid-Neoempheriapun...

BACKGROUND Towards lower latitudes the number of recognized species is not only higher, but also phylogeographic subdivision within species is more pronounced. Moreover, new genetically isolated populations are often described in recent phylogenies of Neotropical birds suggesting that the number of species in the region is underestimated. Previous COI barcoding of Argentinean bird species showe...

ABSTRACT Objective: assess patient responses and associated factors of items on a safe surgery checklist, identify use before after protocol implementation from the records. Methods: cohort study conducted 2014 to 2016 with 397 individuals in stage I 257 II, 12 months implementation, totaling 654 patients. Data were obtained structured interviews. In parallel, 450 checklist assessments performe...

The use of molecular markers has contributed to phylogeny and to the reconstruction of species' evolutionary history. Each region of the genome has different evolution rates, which may or may not identify phylogenetic signal at different levels. Therefore, it is important to assess new molecular markers that can be used for phylogenetic reconstruction. Regions that may be associated with specie...

One new species of the genus Phradis, Phradis peruvianussp. n., from the mountainous part of Peruvian Amazonia, is described and illustrated. This is the first record of the genus from South America and the Neotropical region.
