| Bowdichia virgilioides Kunth, uma leguminosa arbórea comum no cerrado, ocorre no campo sujo, em que predomina o estrato herbáceo e em formações florestais, como o cerradão. Neste estudo investigou-se os efeitos do sombreamento e da seca sazonal no estabelecimento e desenvolvimento dessa espécie nestas duas fitofisionomias. O solo permaneceu úmido durante a maior parte da estação chuvosa, mas curtos períodos sem chuva afetaram o potencial de água das camadas superficiais. Ao longo da estação seca, o solo sob campo sujo secou mais rapidamente. A emergência de plântulas foi maior no campo sujo e a maior parte da mortalidade ocorreu logo após a emergência, durante a estação chuvosa. A estação seca não foi um fator importante de mortalidade. O ambiente... |

| Ophiuroids are conspicuous dwellers of exposed and cryptic microhabitats available in coral reefs. This investigation pretended to discern ophiuroid community composition at microhabitats available in sponges and other reef components of different character (biotic v s. abiotic) or position over the substrate (elevated v s. non- elevated), at shallow reefs within the Montastraea spp. zone at San Bernardo Archipelago (Colombian Caribbean). Evaluating the abundance of organisms related to availability of different microhabitats, schemes of exclusive or preferential occupation of a particular elevated component were determined. These schemes, are discussed as initial cues that suggest the existence of benefic ecological relations. Samplings were performed at... |

| Foraging in the Black Lion Tamarin (L. chrysopygus Mikan, 1823) was observed in the Caetetus Ecological Station, São Paulo, southeastern Brazil, during 83 days between November 1988 to October 1990. These tamarins use manipulative, specific-site foraging behavior. When searching for animal prey items, they examine a variety of microhabitats (dry palm leaves, twigs, under loose bark, in tree cavities). These microhabitats were spatially dispersed among different forest macrohabitats such as swamp forests and dry forested areas. These data indicated that the prey foraging behavior of L. chrysopygus was quite variable, and they used a wide variety of microhabitats, different of the other lion tamarin species. |

| Prey foraging behavior in the Black Lion Tamarin, Leontopithecus chrysopygus (Mikan, 1823) was observed in the Caetetus Ecological Station, southeastern Brazil, during 550 hours of direct observations between December 1993 and February 1995. The scan sampling method was used to gather data. These tamarins use manipulative, specific-site foraging behavior. When searching for animal prey items, they examine a variety of microhabitats. The most important microhabitat used for prey foraging behavior was tree cavities (41% of the foraging observations), but palm trees (22%), bamboo (12%), vines (11%), bark (5%), seed pods of the "jequitiba" tree (4%), other places (3%) and epiphytes (2%) were also observed. Animal preys were frequently captured in understory... |

| Manganese nodules provide an important habitat for sessile benthic organisms, many of them novel foraminifera, in the abyssal Pacific. The surface texture and microhabitat heterogeneity of nodules may play a significant role in structuring these communities. We analyzed the distribution of foraminiferal species on 20 nodules collected using either a USNEL box corer or the Nautile submersible sampling tool at a 5000-m-deep site in the Tropical North Pacific. The nodules had an upper region characterized by two microhabitats, namely raised surfaces and intervening depressed surfaces. The more or less vertical sides of the nodules were regarded as a third microhabitat. The upper region had a predominantly smooth texture while the sides had a rough texture. We... |

| During two consecutive years, from January 1985 to December 1986, a comparative study of mosquitoes preferences for breeding habitat was carried out in the Atlantic Forest of the Serra do Mar, Paraná State, Brazil. To achieve it, 1875 bamboo internodes aligned vertically in live green, bamboo plants Merostachys speciosa Munro and Merostachys sp. were used, in which metabolic water was exuded from the plant itself, and presenting different size/pattern holes at their lateral walls, bored by the local sylvan fauna. Another group of 1200 individual internode traps was used as comparative element, carved out with a transversal cut by a saw, filled with local stream water and held in branches at different heights in the vegetal strata nearby. At both... |

| Como parte do inventário da mixobiota do Parque Nacional Serra de Itabaiana, Sergipe, Nordeste do Brasil (10º40'52''S e 37º25'15''W, 180-670 m.s.m., 7.966 ha), avaliou-se a riqueza, abundância e constância das Stemonitales presentes em diferentes microhabitats e níveis altitudinais. Esporocarpos foram coletados durante 20 meses consecutivos, desde abril/2002 até dezembro/2003; amostras de substratos foram também coletadas para cultivo em câmara-úmida. Coleções do material estudado foram depositadas no Herbário UFP. Foram identificadas 14 espécies de Stemonitidaceae, pertencentes aos gêneros Collaria, Comatricha, Lamproderma, Stemonitis e Stemonitopsis. As espécies foram organizadas em ordem alfabética em uma lista comentada e apresenta-se sua distribuição... |

| The Mediterranean Sea constitutes a unique environment to study cold-seep ecosystems due to the presence of different geodynamic settings, from an active margin along the Mediterranean Ridge (MR) to a passive margin in the Nile Deep-Sea Fan (NDSF). We attempted to identify the structure of benthic communities associated with the Napoli and Amsterdam mud volcanoes (MVs) located on the MR and to establish the links between faunal distribution and environmental conditions at different spatial scales. Comparison between the 2 MVs revealed that the faunal distribution seemed to be mainly controlled by the characteristics of the microhabitats. On both geological structures, the variability between the different microhabitats was higher than the variability... |

| ABSTRACT The composition of the spider fauna of riparian forests is insufficiently known. These forests, adjacent to both aquatic and terrestrial environments, are recognised as having important ecosystem functions. We compare the composition of spider assemblages of four riparian forests in different drainage basins, along with their microhabitats (edges and forest interior), in the state of Rio Grande do Sul, southern Brazil. Sampling was carried out in the riparian forests of the following rivers: Piratini, municipality of Arroio Grande; Camaquã, municipality of Cristal; Sinos, municipality of Parobé, and Maquiné, municipality of Maquiné. Two samples per season were collected in two years, by sampling the tree-shrub strata with a beating tray, following... |
