Three new sharpshooter species of the genus Fonsecaiulus Young, 1977 are described and illustrated from specimens collected in the Brazilian Atlantic Forest, Fonsecaiulus rectangularis and Fonsecaiulus guttiformis, and in the Brazilian Cerrado, Fonsecaiulus filiformis. The descriptions are based on features from the external morphology, color pattern, and male and female genital structures. Com...

A lectin isolated from the red alga Solieria filiformis was evaluated for its effect on the growth of 8 gram-negative and 3 gram-positive bacteria cultivated in liquid medium (three independent experiments/bacterium). The lectin (500 microg/mL) stimulated the growth of the gram-positive species Bacillus cereus and inhibited the growth of the gram-negative species Serratia marcescens, Salmonella...

Study of the control mechanisms of light emission in invertebrates shows the involvement of several neurotransmitters. In ophiuroids, only one species (Amphipholis squamata) has so far been characterized for luminescence control, which seems to be cholinergic, with an influence of several excitatory and inhibitory neuromodulators (amino acids, catecholamines, neuropeptides S1 and S2, purines). ...

We studied the life history, geographic distribution, behavior, and ecology of Larinus filiformis Petri (Coleoptera: Curculionidae) in its native range to determine whether it is worthy of further evaluation as a classical biological control agent of yellow starthistle, Centaurea solstitialis (Asteraceae: Cardueae). Larinus filiformis occurs in Armenia, Azerbaijan, Turkey, and Bulgaria and has ...

La diversidad de la herpetofauna en Amazonía peruana tiene un potencial considerable para conservación, investigación y ecoturismo. Especialmente cuando pérdida especies ha aumentado debido al incremento las actividades antropogénicas. falta conocimientos sobre anfibios reptiles zonas periurbanas nos motivó a realizar esta el Centro Investigación Fernando Alcántara Bocanegra (CIFAB), Iquitos, P...

Parasitism is increasingly recognized as an important determinant of population dynamics, productivity and community structure in intertidal ecosystems, and yet there is very little known about the effect of parasites on polychaetes, which represent a major component of the benthic fauna. We surveyed 11 polychaete species from a mudflat in Otago Harbour, New Zealand, and found that seven of the...

A group of Eubacterium-like strains (designated group S14), isolated from the feces of healthy people, was characterized by biochemical tests, fatty acid analysis, cell wall murein analysis, and 16S rDNA analysis. Our results indicate that group S14 is phylogenetically a member of the Clostridium subphylum of the gram-positive bacteria. Despite a phenotypic resemblance to the genus Eubacterium,...
