Coleta de dados no campo (biológico e social)
Andersen, Alexandre Camargo; Surova, Diana; Oliveira, Ubirajara; Quinta-Nova, L.C.A coleta de dados biológicos e sociais na escala de paisagem é um grande desafio devido as características únicas dessa escala de análise, como grandes extensões, dificuldade de se alcançar uma cobertura espacial amostral com esforço adequado, deficiência de se obter réplicas, controles e de se executar experimentos. Tais particularidades demandam uma clara definição a priori da pergunta a ser respondida, e uma...

de Magalhães, Rafael Félix; Lemes, Priscila; Camargo, Arley; Oliveira, Ubirajara; Brandão, Reuber Albuquerque; Thomassen, HansMade available in DSpace on 2018-12-11T17:23:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-01-01; Protected areas (PAs) are essential for biodiversity conservation, but their coverage is considered inefficient for the preservation of all species. Many species are subdivided into evolutionarily significant units (ESUs) and the effectiveness of PAs in protecting them needs to be investigated. We evalu...
Biodiversity conservation gaps in the Brazilian protected areas
Oliveira, Ubirajara; Soares-Filho, Britaldo Silveira; Paglia, Adriano Pereira; Brescovit, Antonio D.; Carvalho, Claudio J. B. de; Silva, Dasniel PaivaAlthough Brazil is a megadiverse country and thus a conservation priority, no study has yet quantified conservation gaps in the Brazilian protected areas (PAs) using extensive empirical data. Here, we evaluate the degree of biodiversity protection and knowledge within all the Brazilian PAs through a gap analysis of vertebrate, arthropod and angiosperm occurrences and phylogenetic data. Our results show that the...
