Este trabalho tem como objetivo principal compreender e descrever como pescadores artesanais, que tradicionalmente exploram as áreas do entorno e dentro de uma unidade de conservação, mais especificamente o Parque Nacional do Cabo Orange localizado no município do Oiapoque, costa do Amapá, têm se ordenado politicamente e ambientalmente no que se refere à cenários de conflito socioambiental em águas costeiras - por territórios de pesca. Para tanto, o trabalho utiliza uma metodologia qualitativa e privilegia os agentes envolvidos no cenário da pesca no município de Oiapoque, estes são: pescadores paraenses, ICMBio, pescadores amapaenses. Os resultados da pesquisa demonstram que boa parte dos pescadores artesanais associados à Colônia de Pescadores do Oiapoque são remanescentes de uma comunidade pesqueira que era localizada no interior do Parque, chamada Vila de Taperebá. Os Parques Nacionais são um modelo de unidade de conservação de proteção integral à natureza, não permitindo a presença humana ou exploração de seus recursos. Consequentemente, essa população foi expropriada e a partir das entrevistas realizadas foi possível perceber como os pescadores artesanais do Oiapoque, juntamente com a Colônia de Pescadores do Oiapoque, traçaram e propõem um manejo e uma medida compensatória pela expropriação que ocorreu a partir da criação do referido Parque.

The presence of visitors in national parks is desirable and agrees with their management objectives. However, areas and paths under the influence of visitors are sites with a great possibility of change in the composition of vegetation due to the effects caused by the influence of walking, bicycles and horseback riding. In this work, two trails of the Serra do Cipo National Park were evaluated with the aim of studying and knowing the distribution of native and exotic species in their areas of influence. The theme of biological invasions in protected areas has been an important focus of studies since they represent a threat to biodiversity. The results show differences in the presence of exotic plants and conservation conditions between the two tracks studied.

Body size influences wing shape and associated muscles in flying animals which is a conspicuous phenomenon in insects, given their wide range in body size. Despite the significance of this, to date, no detailed study has been conducted across a group of species with similar biology allowing a look at specific relationship between body size and flying structures. Neotropical social vespids are a model group to study this problem as they are strong predators that rely heavily on flight while exhibiting a wide range in body size. In this paper we describe the variation in both wing shape, as wing planform, and mesosoma muscle size along the body size gradient of the Neotropical social wasps and discuss the potential factors affecting these changes. Analyses of 56 species were conducted using geometric morphometrics for the wings and lineal morphometrics for the body; independent contrast method regressions were used to correct for the phylogenetic effect. Smaller vespid species exhibit rounded wings, veins that are more concentrated in the proximal region, larger stigmata and the mesosoma is proportionally larger than in larger species. Meanwhile, larger species have more elongated wings, more distally extended venation, smaller stigmata and a proportionally smaller mesosoma. The differences in wing shape and other traits could be related to differences in flight demands caused by smaller and larger body sizes. Species around the extremes of body size distribution may invest more in flight muscle mass than species of intermediate sizes.

This paper marks an increased refinement and more detailed accuracy in the description of the geological features of the state. It includes the recent studies of mineral deposits, of oil structures, of the formations of bedded rocks and their included fossils, carried on both by the Federal and State governments and by various interested private persons, such as the mining companies. It is within this period that the Federal Government encouraged the U. S. Geological Survey in the publication of monographs on the National Parks, papers of great popular interest and educational value making these beautiful regions comprehensible in their geological features to the touring public.

Este artículo tiene por objetivo analizar y caracterizar el proceso histórico de creación de los parques nacionales en Argentina, desde sus inicios hasta la actualidad, por parte de la autoridad de aplicación, la Administración de Parques Nacionales, tomando como marco conceptual las principales corrientes teóricas en conservación que se fueron sucediendo a lo largo del tiempo. Junto a las fechas de creación de los parques nacionales, su posición geográfica y las ecorregiones donde se localizan, permitieron establecer tres períodos que estuvieron signados por la implementación de políticas públicas en la materia, enmarcadas dentro de los lineamientos generales de dichas corrientes teóricas. Asimismo, se esboza un breve estado de la situación de la preservación en las ecorregiones de nuestro país y, finalmente, se exponen las conclusiones.

Environmental Education (EE) is a key component in any marine protected area management. However, its visibility and action plans are still poorly developed and structured as a clear element in management procedures. The objective of this study is to contribute with a methodological route that integrates EE to the existing model of management planning and strategies, taking the Colombian National Natural Parks System as a case study. The creation of the route is proposed as a participatory research with different stakeholders in order to respond to the specific conservation needs and goals for the National Parks System. The EE national diagnosis has shown that its integration within the parks management structure is a first priority need, being a converging result on the two case studies on National Parks from the Pacific Coast of Colombia. The diagnosis also demonstrates that communication, participation, training and evaluation have to be reinforced, linking the community and stakeholders involved in the park management to the whole EE process. The proposed methodology route has been agreed upon by the National Parks staff and incorporates advice and recommendations from different stakeholders, in order to better include the park users. This step will help us to advance toward sustainable management in marine and coastal protected areas elsewhere, taking into account not only the biological but also the social-cultural prism. The main challenges in the management and conservation of coastal and marine ecosystems today are discussed.

The present data set was used as a training set for a Habitat Suitability Model. It contains occurrence (presence-only) of living Lophelia pertusa reefs in the Irish continental margin, which were assembled from databases, cruise reports and publications. A total of 4423 records were inspected and quality assessed to ensure that they (1) represented confirmed living L. pertusa reefs (so excluding 2900 records of dead and isolated coral colony records); (2) were derived from sampling equipment that allows for accurate (<200 m) geo-referencing (so excluding 620 records derived mainly from trawling and dredging activities); and (3) were not duplicated. A total of 245 occurrences were retained for the analysis. Coral observations are highly clustered in regions targeted by research expeditions, which might lead to falsely inflated model evaluation measures (Veloz, 2009). Therefore, we coarsened the distribution data by deleting all but one record within grid cells of 0.02° resolution (Davies & Guinotte 2011). The remaining 53 points were subject to a spatial cross-validation process: a random presence point was chosen, grouped with its 12 closest neighbour presence points based on Euclidean distance and withheld from model training. This process was repeated for all records, resulting in 53 replicates of spatially non-overlapping sets of test (n=13) and training (n=40) data. The final 53 occurrence records were used for model training.
