BACKGROUND A series of databases is being prepared to list the valid species of Opiliones worldwide. This paper containing nomenclatural acts is meant to accompany Part 2, which includes the members of the infraorder Grassatores of the superfamilies Samooidea and Zalmoxoidea plus the Grassatores currently not allocated to any family (i.e. Grassatores incertae sedis). NEW INFORMATION The follo...

the present study reports range extansion of moenkhausia oligolepis to the pindaré river drainage, of the mearim river basin, and itapecuru river basin, maranhão state, northeastern brazil. this species was previously known only from venezuela, guianas, and the amazon river basins. in addition, we present some meristic and morphometric data of the specimens herein examined and discuss on its di...

The clinical and bacteriological features of a case of endocarditis are described in which a Gram-positive coccus, presently designated Micrococcus sedentarius incertae sedis, was repeatedly isolated.

The influence of ecological traits to the distribution and abundance of species is a prevalent issue in biodiversity science. Most studies of plant community assembly have focused on traits related to abiotic aspects or direct interactions among plants, with less attention paid to ignore indirect interactions, as those mediated by pollinators. Here, we assessed the influence of phylogeny, habit...

BACKGROUND Antimicrobial use is thought to suppress the intestinal microbiota, thereby impairing colonization resistance and allowing Clostridium difficile to infect the gut. Additional risk factors such as proton-pump inhibitors may also alter the intestinal microbiota and predispose patients to Clostridium difficile infection (CDI). This comparative metagenomic study investigates the relation...

A gram-positive coccus, presently named Micrococcus mucilaginosus incertae sedis, was isolated from 14 blood cultures from a patient with endocarditis. The first positive blood culture was drawn 5 days after the patient underwent cardiac catheterization.

Fossil specimens of Neotropical gymnotiform electric fishes from the Yecua Formation (Upper Miocene, Parana basin, Bolivia) are analyzed in the context of a comprehensive study of gymnotiform relationships. Each fossil is analyzed individually and placed in the phylogeny according to characters it actually possesses. Some of the fossils previously referred to Humboldtichthys kirschbaumi can be ...

The phylogeny of the genera Periconiella, Ramichloridium, Rhinocladiella and Veronaea was explored by means of partial sequences of the 28S (LSU) rRNA gene and the ITS region (ITS1, 5.8S rDNA and ITS2). Based on the LSU sequence data, ramichloridium-like species segregate into eight distinct clusters. These include the Capnodiales (Mycosphaerellaceae and Teratosphaeriaceae), the Chaetothyriales...

Here we report three complete bacterial genome assemblies from a PacBio shotgun metagenome of a co-culture from Upper Klamath Lake, OR. Genome annotations and culture conditions indicate these bacteria are dependent on carbon and nitrogen fixation from the cyanobacterium Aphanizomenon flos-aquae, whose genome was assembled to draft-quality. Due to their taxonomic novelty relative to previously ...
