| El área de anidación de Punta Francés es un tramo de alrededor de 3 km de largo, con una franja arenosa estrecha. La playa es de baja energía, con la excepción de determinados tramos en donde la dinámica del oleaje es mayor. Presenta una vegetación costera típica con predominio del incienso de costa (Tournefortia gnaphalodes). La arena es de grano fino y color claro. Las zonas de mayor anidación se concentran en los tramos de arena más gruesa y oscura, ubicados hacia los extremos de la playa, pero, los niveles de anidación, que no superan los 25 nidos en ninguna de las temporadas analizadas, son bajos comparados con otras áreas del archipiélago cubano. La presencia de arrecifes paralelos a la costa pudiera disminuir la accesibilidad de las playas... |

| Ants are among the most common arthropods that colonize termite nests. The aim of this study was to identify the ant fauna associated to termite nests found in a cacao plantation in the county of Ilhéus, Bahia, Brazil, with emphasis on the fauna that uses the nests as foraging and/or nesting environment. For this purpose, 34 active, decadent and abandoned nests of Nasutitermes corniger, N. ephratae and Nasutitermes sp., with different volumes and degrees of activity, were dissected. A total of 54 ant species, belonging to 23 genera and five subfamilies, was found in the constructions. The active, decadent and abandoned termite nests presented, respectively, six, eight and 48 ant species. Crematogaster acuta and Ectatomma tuberculatum were the most frequent... |

| The San Bernardo Archipelago, in the Colombian Caribbean zone, is well recognized for being a sporadic nesting and feeding area for the green, hawksbill and loggerhead turtles. Due to the fact that the San Bernardo Archipelago has outstanding coral areas, marine grasses and sandy beaches and their environmental offers for the marine turtles have not been described yet, it was opportune to carry out this study between July and October of 2002. Thus, this research tends to fill this gap by describing the nesting beaches and feeding areas according to their geomorphologic and biotic aspects and, for the later areas, some oceanographic aspects too. Seven potential nesting beaches and 20 stations on feeding areas were evaluated to identify natural and... |

| Este artigo analisa o processo de implantação da agricultura orgânica em assentamentos de reforma agrária, ainda recente no Brasil, e que trouxe consigo uma rápida transformação para a agricultura familiar. Procura analisar a contribuição da agricultura orgânica como alternativa de sustentabilidade sócio- econômica e ambiental da produção e entender o processo de reforma agrária brasileira e suas dificuldades, mostrando os possíveis caminhos para o agricultor assentado agregar valor à produção e se inserir em uma economia de mercado. Além do que, analisa os impactos identificados na elevação da renda familiar e melhoria nas condições de vida. Procurou-se analisar o caso do assentamento Ronda/Chico Mendes, no município de Pombos, em Pernambuco. A pesquisa... |

| Se realiza un análisis de la tendencia de la anidación para la tortuga verde (Chelonia mydas) y la caguama (Caretta caretta) en sus principales áreas de reproducción en el Archipiélago de los Canarreos, a partir de la cuantificación de los nidos encontrados en el período 2001-2006. Los resultados indican incremento de la anidación de la tortuga verde para todos los sitios de puesta del Archipiélago y de la tortuga caguama para las playas de los Cayos de San Felipe y de Cayo Largo, aunque en ninguno de los sitios fue significativo estadísticamente. Sin embargo, para la caguama hay decrecimiento de 46 a 24 nidos en el Sur de la Isla de la Juventud y de 75 a 17 nidos para las playas de los cayos al este de la misma, posiblemente por aumento de la depredación... |

| Using large and small nest boxes I determined the effect of the nest box size upon nesting and renesting probability, as well as the reproductive success of two secondary cavity nesters, the thorn-tailed rayadito (Aphrastura spinicauda) and the house wren (Troglodytes aedon) was determined comparing large and small boxes. In order to assess these effects nest boxes were monitored by two consecutive years. Results indicated that Aphrastura nested mainly in the large instead of the small nest boxes, and nesting Troglodytes used primarily small nest boxes. Nevertheless, the renesting pattern of both species, including renesting attempts after successful fledging and after nest failure, was not affected by nest box size and the probability of renesting was not... |

| A research programm on the marine green turtle Chelonia mydas nesting on the two major reproduction sites for the species in the Indian Ocean, conducled over last 15 years, included intensive tagging programm. Processing of these lagging data provides estimations of adult female populations {or each site and season from two independent methods. First classical method is the ratio of total number of nests produced over a define time on the mean individual number of nests by female during the same time (November, December, January). The computed mean individual number ranges from 3 to 3.5 obtained over 2 to 3 months. The second method is the multiple capture-recapture method (JOLLY, 1965; SEBER, 1965; MANLY, 1984). Il is an original tentative of applying... |

| Se determinó el éxito de los nidos para las tortugas verde (Chelonia mydas) y caguama (Caretta caretta), a partir de monitoreos realizados en playa El Guanal (Sur de la Isla de la Juventud), durante las temporadas reproductivas 2008, 2009 y 2010. Se tomaron como indicadores, Éxito de Emergencia (EE), Neonatos Eclosionados Muertos (NEM), Huevos con Embriones Muertos (HEM) y Huevos Sin Desarrollo Aparente (HSDA). En tortuga caguama, ninguno de los indicadores medidos mostró diferencias significativas en todo el período de estudio, p > 0,05. En cuanto a la tortuga verde los valores medios del EE se mantuvieron entre 71,6 y 88,2 %, disminuyendo significativamente en las temporadas 2009 y 2010 (p < 0,05), mientras el indicador HEM aumentó... |

| A group of several Andean Parakeet (Bolborhynchus orbygnesius) individuals was observed, photographed and tape-recorded at Finca El Candado, near Los Cardones National Park, Salta Province, northwestern Argentina. There is no previously published record of Andean Parakeet from south of Cochabamba, Bolivia, although there is a tape-recording from Tarija, Bolivia, which is about 350 km north-northwest of Finca El Candado. Additionally, there is an undocumented record of a group of birds 218 km north-northwest of Finca El Candado, between Valle Colorado and Santa Ana, in Jujuy Province, Argentina. Birds were coming to roost in a large stick nest that did not look like any described nest. We do not know if the parrots had constructed this nest entirely or... |

| The Magdalena River Turtle, Podocnemis lewyana, is an endangered and endemic turtle from Colombia. Among the most important information needed to conserve endangered species is to identify, monitor, and protect the sites used by the species to reproduce and grow. In this study we report, for the first time, the reproductive output and the nesting beaches of P. lewyana in the Claro Cocorná Sur River, a tributary of the Magdalena River drainage. We systematically examined a river transect of 8 km with 14 sandy beaches during two nesting seasons in one year. We recorded a yearly production of 47 clutches, 957 eggs, and two preferred nesting beaches: Alto Bonito with 51 %, and Bélgica with 28.3 % of this reproductive output. AAFUVER, a community-based... |
