Tropical tree growth driven by dry-season climate variability
Zuidema, Pieter A.; Babst, Flurin; Groenendijk, Peter; Trouet, Valerie; Abiyu, Abrham; Acuña-Soto, Rodolfo; Adenesky-Filho, EduardoInterannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empirical evidence to quantify the responsible ecological processes is missing. Such evidence can be obtained from tree-ring data that quantify variability in a major ve...
Avifauna of the Serra de Itabaiana National Park revisited: additions and delet...
Silva, Cleverton da; Ruiz-Esparza, Juan; Azevedo, Cristiano Schetini de; Ribeiro, Adauto de SouzaThe Serra de Itabaiana National Park (PARNASI) is known as an important conservation area in the ecotone between the Atlantic Forest and Caatinga in Northeast Brazil and is one of the main areas of fauna and flora studies in Sergipe. For this reason, there are some studies on its avifauna, which date back to its creation in 2005. However, after 15 years of establishment of PARNASI, an update of the inventory of...
Birds of prey (Accipitriformes and Falconiformes) of Serra de Itabaiana Nationa...
Silva, Cleverton da; Azevedo, Cristiano Schetini de; Ruiz-Esparza, Juan; Ribeiro, Adauto de SouzaBirds of prey are important for maintaining ecosystems, since they can regulate the populations of vertebrates and invertebrates. However, anthropic activities, like habitat fragmentation, have been decreasing the number of birds of prey, affecting the habitat ecological relations and, decreasing biodiversity. Our objective was to evaluate species of birds of prey (Accipitriformes and Falconiformes) in a protec...
Diversidade de carnívoros (Mammalia: Carnivora) da Serra dos Macacos, Tobias Ba...
Dias, Douglas de Matos; Ribeiro, Adauto de Souza; Bocchiglieri, Adriana; Pereira, Taiguã CorrêaThe worldwide anthropogenic reduction of the habitat available to carnivores that depend on large home ranges has seriously threatened many species. In this context, reliable data on the occurrence and abundance of species are vital to conservation efforts. This study inventoried the carnivore fauna of the Serra dos Macacos in Tobias Barreto, Sergipe (Brazil). Between October 2010 and August 2011, carnivores we...
Floristic characterization of Ibura national forest, Sergipe, Brazil
Santana, José Paulo; da Rocha, Patrício Adriano; da Silva, Thalita Rocha; Ribeiro, Adauto de Souza; Prata, Ana Paula do NascimentoThe aim of this study was to obtain information on the floristic composition and dispersal syndromes of the Ibura National Forest and carry out an analysis of similarity with other floristic surveys in the state of Sergipe. For this purpose, bimonthly sampling was carried out from September 2012 to December 2014. Total of 328 species were recorded, of which 324 were angiosperms belonging to 82 families, followe...
Birds of the Grota do Angico Natural Monument in the semi-arid caatinga scrubla...
Ruiz-Esparza, Juan; Gouveia, Sidney Feitosa; Rocha, Patrício Adriano da; Mendes, Raone Beltrão; Ribeiro, Adauto de Souza; Ferrari, Stephen FrancisMedicinal plants are an important source of treatment for many ailments, although little is known of the potential genotoxic effects of most species. In the present study, two species from diverse and medicinally important genera - Maytenus rigida Mart., Celastraceae, and Aristolochia birostris Ducht, Aristolochiaceae - were analyzed to identify potentially significant secondary metabolites and the possible eff...
Post-fire regeneration of vegetation on sandy oligotrophic soil, in Itabaiana, ...
Dantas, Túlio Vinicius Paes; Ribeiro, Adauto de Souza; Sampaio, Everardo Valadares de Sá Barretto; Araújo, Elcida de LimaTwo models of post-disturbance regeneration of vegetation in areas of oligotrophic soils have been proposed for temperate regions. The first model is characterized by rapid recovery of the floristic composition, due to the fire resistance of plants; while in the second model, the fire causes extensive mortality and the recovery occurs by recruitment from the seed bank. Since these models have been rarely tested...
Diversidade de carnívoros (Mammalia: carnivora) da serra dos macacos, Tobias Ba...
Dias, Douglas de Matos; Ribeiro, Adauto de Souza; Bocchiglieri, Adriana; Pereira, Taiguã CorrêaA redução dos habitats dos carnívoros que necessitam de grandes áreas de vida tem ameaçado seriamente muitas espécies em todo o planeta, cujas causas estão relacionadas, quase sempre, às atividades antrópicas. Nesse sentido, esforços de pesquisa de campo são imprescindíveis, de modo a contribuir com informações sobre ocorrência e estado de conservação das espécies. Este estudo teve como objetivo inventariar a f...

Apicultura uma alternativa na busca do desenvolvimento sustentável
Ribeiro, Adauto de Souza; Santos, Cristiane Soares dosEste trabalho teve como objetivo fazer uma análise de como a relação sociedade e natureza foi se modificando ao longo dos tempos, argumentando a importância da apicultura como uma atividade capaz de promover o desenvolvimento regional ao mesmo tempo em que conserva o meio ambiente. Falar em sociedade, natureza e desenvolvimento é falar na dinâmica humana e suas implicações enquanto propulsora de ideologias, cor...
