Functional antagonism between nitrogen-fixing leguminous trees and calcicole-dr...
Meira-Neto, João Augusto Alves; Tolentino, Gláucia Soares; Silva, Maria Carolina Nunes Alves da; Neri, Andreza Viana; Gastauer, MarkusThe Cerrado is the largest savanna of South America and its physiognomy varies from savanna to woodlands. There are two main types of woodlands in the Cerrado: dystrophic woodlands, dominated by N-fixing leguminous trees (LEG), and mesotrophic woodlands dominated by non-leguminous drought-tolerant trees (DRY), which are calcicoles and sensitive to Al3+. The working hypothesis is that LEG and DRY are functional ...
Early Acacia invasion in a sandy ecosystem enables shading mediated by soil, le...
Meira-Neto, João Augusto Alves; Silva, Maria Carolina Nunes Alves da; Tolentino, Gláucia Soares; Gastauer, Markus; Buttschardt, Tillmann; Ulm, FlorianAustralian species of the genus Acacia are amongst the most invasive trees. As nitrogen fixers, they are able to invade oligotrophic ecosystems and alter ecosystem functioning to their benefit. We aimed to answer three questions: How does early Acacia invasion influence nitrogen and light in a sandy savanna? How does early Acacia invasion impact biodiversity? Does early invasion alter ecosystem functioning towa...
Processos ecológicos e invasão biológica por Acacia mangium Willd nos ecossiste...
Silva, Maria Carolina Nunes Alves daCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Invasões biológicas são consideradas uma das maiores ameaças à biodiversidade dos ecossistemas, atuando em mudanças nas regras de montagem das comunidades vegetais. Acácias australianas são frequentemente associadas à diminuição da riqueza de espécies nativas, pela inibição do estabelecimento de suas plântulas através da competição ainda na fase de es...
Dinâmica e ecologia funcional das espécies lenhosas de Cerrado na FLONA de Para...
Silva, Maria Carolina Nunes Alves daThe succession and vegetation dynamics is the form how the species composition and physiognomy of vegetation, change a particular location over time. Regardless of the taxonomic or phylogenetic relationships,the functional classification of plants allows the gathering of groups of species that respond similarly to biotic and abiotic factors, allowing better understanding the ecosystem. The aim of this study was...
