| New record and additions to the Argentinean bryophyte flora. Steereella lilliana is reported as a new record for the bryophyte flora in Argentina and South America. Furthermore, the distribution of Frullania brasiliensis in Argentina, previously known only from Misiones and Salta, is expanded to the provinces of Tucumán and Córdoba. Additionally, Stephaniella paraphyllina, is new to the province of San Luis, collected in Sierra de Comechingones, and this represents its southernmost distribution. Brief comments about morphological characters, keys to related species in Argentina, as well as habitat details are given. |

| En México se consignan 45 especies para el género Jatropha (Euphorbiaceae). La Reserva de las Biosfera de Tehuacán-Cuicatlán concentra riqueza genética y endemismo para este género, que proporciona alimento, medicina y energía a los habitantes, pero falta información sobre la distribución, ecología y aprovechamiento de las especies. Esta tesis se organizó en tres capítulos. En el primero se precisaron taxonómicamente las especies de Jatropha, se diferenciaron las Unidades Ambientales (UA) en las que habitan, se valoró el estado de conservación de sus hábitats y se calificó la vulnerabilidad de sus poblaciones; en el segundo capítulo, se verificó la variación morfológica intra e interespecífica; y, en el último, se caracterizó el aprovechamiento... |

| Competing claims on natural resources become increasingly acute, with the poor being most vulnerable to adverse outcomes of such competition. A major challenge for science and policy is to progress from facilitating univocal use to guiding stakeholders in dealing with potentially conflicting uses of natural resources. The development of novel, more equitable, management options that reduce rural poverty is key to achieving sustainable use of natural resources and the resolution of conflicts over them. Here, we describe an interdisciplinary and interactive approach for: (i) the understanding of competing claims and stakeholder objectives; (ii) the identification of alternative resource use options, and (iii) the scientific support to negotiation processes... |

| River ecologists are also river-basin planners. However, their role in planning has developed slowly over the decades since the beginning of the 20th century. Three major factors explain this phenomenon. First, ecologists focused on plant and animal communities rather than on broader policy issues related to land settlement and water development. Second, the federal government, and most state and local governments as well, used mainly economic criteria to justify projects. Intangible benefits, including the value of species or an aesthetically pleasing landscape, drew relatively little attention. Third, the public generally favored development, especially during the Great Depression of the 1930s. Only after World War II did the public's position shift in... |

| Ecological research, especially work related to conservation and resource management, increasingly involves social dimensions. Concurrently, social systems, composed of human communities that have direct cultural connections to local ecology and place, may draw upon environmental research as a component of knowledge. Such research can corroborate local and traditional ecological knowledge and empower its application. Indigenous communities and their interactions with and management of resources in their traditional territories can provide a model of such social-ecological systems. As decision-making agency is shifted increasingly to indigenous governments in Canada, abundant opportunities exist for applied ecological research at the community level.... |

| Building models is an important way of integrating knowledge. Testing and updating models of social-ecological systems can inform management decisions and, ultimately, improve resilience. We report on the outcomes of a six-year, multidisciplinary model development process in the sagebrush steppe, USA. We focused on creating state-and-transition models (STMs), conceptual models of ecosystem change that represent nonlinear dynamics and are being adopted worldwide as tools for managing ecosystems. STM development occurred in four steps with four distinct sets of models: (1) local knowledge elicitation using semistructured interviews; (2) ecological data collection using an observational study; (3) model integration using participatory workshops; and (4)... |

| In Thailand, mangrove forests are claimed for state management, although it is widely recognized that coastal communities access and manage those forests. Skepticism persists within Thai government circles about whether coastal villages can sustainably manage and protect mangroves. This research presents evidence of successful mangrove conservation and management by two coastal villages in Trang province, southern Thailand. Using interdisciplinary methods including interviews, discussions, quantitative forest surveys, and institutional analysis, we describe the history of how these two communities gained rights to manage the mangrove forests, and the subsequent positive biological outcomes associated with their management. Local villages have crafted and... |

| The ostracode assemblages from Cananéia-Iguape estuarine/lagoon system (southernmost State of São Paulo) are here discussed in detail for the first time. Thirty-four sites, approximately 1 km equidistant, were sampled along the system, including the Cananéia Sea, Pequeno Sea, Cubatão Sea, Ribeira de Iguape River and Itapitangui River. The ostracodes throughout this area have poor assemblages, with a total of 662 specimens of dead and living organisms. The majority of the ostracode fauna is composed of euryhaline species, as follows: Cyprideis multidentata Hartmann, 1955 (174 specimens), Minicythere heinii Ornellas, 1974 (54 specimens), Tanella gracilis Kingma, 1948 (96 specimens) and Whatleyella sanguinettiae Coimbra, Carreño & Ferron, 1994 (226... |

| A field survey of flowering plants used as food resource by the adults of Heliconius erato phyllis (Fabricius, 1775) was carried out in four sites located in Rio Grande do Sul state, Brazil. Samples were taken in preserved areas of the Atlantic Rain and Myrtaceae forests, an Eucalyptus plantation, and an urban park. Adult feeding frequencies on flowers were registered monthly from December 1996 to May 1997, on plants located on previously marked 200 m long transects. Flowers on which H. erato phyllis fed in the field were collected, drawn and morphometrically characterized. Feeding was registered on flowers of twenty-three species, of which seventeen are new records for H. erato in Brazil . The use of a given plant varied among localities, as a function of... |

| Recruitment and colonization of colonial ascidians, starting on natural scraped substratum, was observed throughout one year, in quadrats marked on sea- and continental-rock faces in the sublittoral fringe of an exposed beach in the Northeast of Brazil. The species of the Didemnidae, Didemnum duplicatum Monniot, 1983, D. psammathodes Sluiter, 1895, and Polysyncraton amethysteum Van Name, 1902, and an unidentified species of Polycitoridae, Eudistoma sp. 1, were recruited. Presenting continuous recruitment of all species, the density of living and dead recruits and colonies was similar on both faces of the rocks. The highest rainfall during winter, affected significantly the recruits density of D. duplicatum and D. psammathodes. Different permanence periods... |

| The ecology of Eudendrium spp. from the Brazilian coast is poorly known, although it already proved to be useful and important as a tool to solve some taxonomical problems of the genus. The seasonality and reproduction patterns of a population of Eudendrium caraiuru Marques & Oliveira, 2003 were studied. Data were sampled from test panels immersed in the water off Cabelo Gordo de Dentro beach, in São Sebastião Channel, Southeastern Brazil, from July 1999 to July 2000, every three months. Eudendrium caraiuru was active throughout the study period. Reproductive peaks of the species were regulated by cold and low-salinity water, although part of the population always bore mature gonophores. In addition to morphological differences, ecological... |
