- 1From: Brazilian Journal of Biology. (Vol. 68, Issue 1) Peer-ReviewedPhotoacclimation of photosynthesis was investigated in a tropical population of C. glomerata (Sao Paulo State, southeastern Brazil, 20° 48' 24" S and 49° 22' 24" W) by chlorophyll fluorescence parameters and chlorophyll...
- 2From: Brazilian Journal of Biology. (Vol. 68, Issue 2) Peer-ReviewedThe genus Anicla Grote, 1874 is composed of eleven species; their larvae are harmful, mainly to native and cultivated grasses, but up to now, there is information available of only two species. This study aims at...
- 3From: Brazilian Journal of Biology. (Vol. 68, Issue 3) Peer-ReviewedThe increase in the research of cetacean surveys on the Brazilian coast has brought new data on the distribution of species never reported before. The present work reviews the current knowledge on cetaceans species and...
- 4From: Brazilian Journal of Biology. (Vol. 68, Issue 4) Peer-ReviewedThis work evaluated the effect of food restriction and refeeding of matrinxa females, Brycon amazonicus, on their reproductive performance and on the growth and survival of the progeny. Broodstocks were distributed in 8...
- 5From: Brazilian Journal of Biology. (Vol. 68, Issue 1) Peer-ReviewedSeveral groups of Amazonian fishes exhibit behavioral, morphological and physiological characteristics that allow occupying hypoxic environments, despite the energetic costs of living in such harsh conditions. One of the...
- 6From: Brazilian Journal of Biology. (Vol. 68, Issue 2) Peer-ReviewedThe family Spirorchiidae includes trematodes of freshwater and marine chelonian blood vessels. Up to now, Learedius learedi Price, 1934 has been the only species of this family described in Brazil (Werneck et al., 2006)....
- 7From: Brazilian Journal of Biology. (Vol. 68, Issue 5) Peer-ReviewedAquatic macrophytes comprises a diverse group of organisms including angiosperms, ferns, mosses, liverworts and some macroalgae that occur in seasonally or permanently wet environments. Among other implications, aquatic...
- 8From: Brazilian Journal of Biology. (Vol. 68, Issue 4) Peer-ReviewedMicro- and mesozooplankton were studied in the Sergipe estuary, northeastern Brazil, in order to assess the temporal variability in abundance and biodiversity under stressed conditions (urban pollution). Zooplankton...
- 9From: Brazilian Journal of Biology. (Vol. 68, Issue 4) Peer-ReviewedMany species of microhymenopterous parasitoids have been registered on Phyllocnistis citrella, the citrus leafminer. The present study aimed to identify the spatial distribution pattern of the native and introduced...
- 10From: Brazilian Journal of Biology. (Vol. 68, Issue 3) Peer-ReviewedThe Phytoplankton community and the abiotic factors of the Cruzeta reservoir were studied at three depths, surface, middle (2 m) and bottom, from September, 2004 to June, 2005, in order to characterize the environment...
- 11From: Brazilian Journal of Biology. (Vol. 68, Issue 4) Peer-ReviewedThe aim of this study was to inventory the species of small mammals in Uberlandia, Minas Gerais, Brazil, based on regurgitated pellets of the barn owl and to compare the frequency of rodent species in the diet and in the...
- 12From: Brazilian Journal of Biology. (Vol. 68, Issue 1) Peer-ReviewedThis study aimed to discuss and describe the oxygen consumption during aerobic mineralization of organic products (cells and excretion products) from five unialgal cultures: Cryptomonas sp., Microcystis aeruginosa,...
- 13From: Brazilian Journal of Biology. (Vol. 68, Issue 3) Peer-ReviewedIn bird mixed flocks, a prominent species, the so-called nuclear species, improves the cohesion and maintenance of the flocks, while other less conspicuous species are assumed as satellite. In this study we described the...
- 14From: Brazilian Journal of Biology. (Vol. 68, Issue 2) Peer-ReviewedAtherinella blackburni is a silverside species whose occurrence on the Brazilian coast was not properly registered until recently. So far, records of its distribution along the Brazilian shore were limited to Itaparica...
