| El estudio tiene el propósito de analizar las actividades productivas en familias rurales del municipio de Zinacantán, Chiapas. Se fundamenta en áreas de participación del desarrollo comunitario.La metodología utilizada incluye técnicas de investigación cualitativa: observación directa y participativa, entrevistas a informantes claves y opinión de encuestados; la información se obtuvo a través de un cuestionario aplicado a 92 jefes de familia. El análisis de datos se realizó con estadística descriptiva apoyada en el programa Statistical Product and Service Solutions (SPSS), distribución de frecuencias, coeficientes de correlación de Pearson, comparación de medias, medidas de tendencia central y dispersión. El estudio muestra que hay escasa organización,... |

| The anurofauna inhabiting higher montane Atlantic forest areas in southeastern Brazil, which often attain heights of more than 2000 m, is still insufficiently known. In this study, we present data on anuran species composition and abundances in two high-altitude (i.e. > 1000 m) sites within the Parque Estadual dos Três Picos (PETP), in the state of Rio de Janeiro. Field surveys were done at altitudes between 1100 and 1900 m above sea level. We recorded 35 species during our study, adding 22 records to the set of anuran species previously known to occur within the PETP. The stability of the species accumulation curve, as well as the richness estimations, showed that the sampling methodology employed and the total sampling effort were appropriate to... |

| Since 1994, Mediterranean research organisations have carried out yearly standardized bottom trawl surveys along the coasts of the Mediterranean Sea from Gibraltar to the Aegean Sea (Medits surveys). A dynamic indicator-based approach to the assessment of multi-stock fisheries has been applied to the data series obtained from these surveys by an international working group involving all the scientific teams contributing to the data collection process. The application was done according to the 13 GFCM geographical sub-areas sampled by the Medits surveys. While reference points for a lot of fished populations and community indicators are seldom available, reference directions are well established for some indicators, giving guidelines for fishery management.... |

| This short review presents the results obtained in several localities of Brazil on the composition of forest bird communities. Data were collected since the late 80's, after we introduced a new methodology of quantitative survey, based on acoustic identification and unlimited-radius point census. Although these data are still scattered, they show uniquely precise and coherently comparative patterns of composition of forest bird communities. Our methodology has the advantage of being absolutely non-disturbing, highly efficient in the field and immediately processed. Results confirm that the structure of a bird community is a good indicator of biodiversity, particularly useful where biodiversity is high. Many of these data are available only in unpublished... |

| To assess the adequacy of medical prescriptions for community-acquired pneumonia at the emergency department of the Hospital de Clínicas de Porto Alegre, we conducted a prospective cohort study, from January through April 2011. All patients with suspected pneumonia were selected from the first prescription of antimicrobials held in the emergency room. Patients with a description of pneumonia, community-acquired pneumonia, respiratory infection, or other issues related to community-acquired pneumonia were selected for review. Two-hundred and fifteen patients were studied. Adherence to the hospital care protocol was: 11.2% for the initial recommended tests (chest X-ray and collection of sputum sample), 34.4% for blood cultures, and 92.1% for the... |

| This study was carried out in the Base Operacional Geólogo Pedro de Moura (BOGPM) in the Urucu River Basin, Coari, state of Amazonas, Brazil, during April, June, and October 2007, in 16 areas, 4 in primary forests (environment MT) and 12 in gaps (environments C1, C2, and C3) at different stages of vegetation recovery, with different plant cover height. We collected 3,547 specimens of flesh flies. The 3,525 individuals identified to species level included 10 genera, 6 subgenera, and 23 species. Sarcodexia lambens (Wiedemann) (47.1%) and Peckia (Peckia) chrysostoma (Wiedemann) (19.1%) were the most abundant species. The abundance patterns and estimated richness differed between the environments, and were separated in two groups, one of the gaps (C1, C2, and... |

| ABSTRACT The present study encompasses the species composition and ecological characteristics of the snake community in a Cerrado-Amazon transition zone in Midwest of Brazil (state of Mato Grosso). The data were collected during six excursions to the "Tanguro" (study area) by visual encounter survey, pitfall traps with drift fences and non-systematic sampling. We collected 194 specimens, distributed in 34 species, 26 genera, and eight families. The most abundant species were Crotalus durissus Linnaeus, 1758 (n = 50), Philodryas olfersii (Lichtenstein, 1823) (n = 15), Philodryas nattereri Steindachner, 1870 (n = 13), Xenodon rabdocephalus (Wied, 1824) (n = 12), Lachesis muta (Linnaeus, 1766) (n = 10) and Erythrolamprus almadensis (Wagler, 1824) (n = 10).... |

| Sandy beaches are among the most extensive environments in Brazil and are generally threatened by disorderly urban growth due to their location along the coast, where human populations tend to concentrate. This is especially true in southeastern Brazil, where the largest urban areas are located. Thus, better knowledge regarding these natural resources is of considerable importance. The surf zone of sandy beaches is inhabited by a number of fish species, including juveniles seeking both food and shelter from predators. An ecological survey was conducted in the surf zone of Itamambuca beach in the city of Ubatuba, São Paulo State, Brazil, in order to evaluate the composition, structure and dynamics of the fish fauna using community descriptors. Diurnal and... |

| The cerrado's flora comprises aluminum-(Al) accumulating and non-accumulating plants, which coexist on acidic and Al-rich soils with low fertility. Despite their existence, the ecological importance or biological strategies of these functional groups have been little explored. We evaluated the leaf flushing patterns of both groups throughout a year; leaf concentrations of N, P, K, Ca, Mg, S, Al, total flavonoids and polyphenols; as well as the specific leaf area (SLA) on young and mature leaves within and between the groups. In Al-accumulating plants, leaf flushed throughout the year, mainly in May and September; for non-accumulating plants, leaf flushing peaked at the dry-wet seasons transition. However, these behaviors could not be associated with... |
