A dinâmica da comunidade arbórea e de 26 populações componentes foi investigada em um fragmento floresta estacional semidecídua Piedade do Rio Grande, Minas Gerais, com base inventários conduzidos 1999 2004 30 parcelas 400 m², 12 das quais foram locadas na borda 18 seu interior. O objetivo verificar se a arbóreas (a) estavam estáveis no período, (b) mostraram uma mais acelerada que Foram obtidas taxas mortalidade recrutamento árvores ganho perda área basal para amostra total, seus dois...
In this study, we evaluated variation in vegetative and reproductive phenological events of four phylogenetically related plant species subjected to a seasonal environment. To aim, sampled 15 individuals each every fortnight for one year, between January December 2017. assess when given phenophase occurred more intensely the population, Fournier intensity index was used synchrony sample event estimated using activity index. The Rayleigh (Z) test determine whether have distribution....
A dinâmica do componente arbustivo-arbóreo foi investigada em uma floresta de galeria aluvial Poços Caldas, Minas Gerais, entre 1998 e 2005. Os objetivos principais foram: investigar se as taxas das florestas aluviais são inferiores a outras formações florestais ripárias tropicais e, inundações periódicas geram variação espacial na no sentido Rio-Borda. amostragem composta 101 parcelas 10 × m, distribuídas 5 blocos ao longo de, aproximadamente, 8 km da Rio Antas. Cada bloco dividido 3...
Abstract Aims Plants have limited resources for defenses and species that invest in biotic might exhibit leaves less other types of defenses. We investigated whether plants few mechanical defenses, but extrafloral nectaries (EFNs) patrolled by ants, are prone to herbivory, compared with without EFNs tougher leaves. Methods Data from the literature were extracted examine reported levels herbivory or EFNs. In a savanna vegetation southern Brazil, field data collected six tropical specific leaf...
RESUMO Este trabalho objetivou avaliar o crescimento e sobrevivência de sete espécies arbóreas nativas em diferentes tratamentos, uma área degradada na Reserva da COPASA (Juramento, MG). Para tal, foram utilizados aproximadamente 1,2 ha área, onde plantadas 899 mudas, (Anadenanthera colubrina, Copaifera langsdorffii, Dilodendron bipinatum, Myracrodruon urundeuva, Pterogyne nitens, Schinopsis brasiliensis Senegalia polyphylla), acompanhadas durante 24 meses. A foi dividida cinco parcelas 0,24...
Fragmentation is one of the main causes biodiversity loss in tropical forests through consequences on their different components. Beta diversity patterns across fragments have been studied multiple spatial scales, but comparisons with intact landscapes and a variety vegetation types are scarce. In order to address this issue anthropogenic landscape disturbance, we tested two hypotheses relating fragmentation beta diversity: 1. Floristic homogenization at patch-level scale 2. differentiation...
Gullies are an expression of intense environmental degradation, particularly soil and vegetation. The objective this work was to characterize the natural regeneration vegetation planted in gully areas south Minas Gerais State, Brazil, so distribution occurrence species can generate useful information for adequate diagnosis on development stage gullies conservation. study involved characterization present different segments areas, bed, bare middle third (BMT), with cover (MTVC), a fragment...
Abstract We present a taxonomic treatment of the Malvaceae from Serra do Lenheiro, montane range in municipality São João del-Rei, Minas Gerais, Brazil, order to contribute knowledge this family and state’s flora. Eleven genera twenty-nine species were recorded. Sida, Pavonia Peltaea are richest genera. Among recorded species, nine considered as ruderal ten endemic Brazil. Three have del-Rei type-locality. Analytic keys, morphological descriptions, photographic plates comments about treated...
RESUMO Nós apresentamos o tratamento taxonômico para a família Orobanchaceae da Serra de São José e do Lenheiro, no Estado Minas Gerais, Brasil. Seis espécies quatro gêneros foram registrados. Chave identificação, descrições morfológicas, fotos comentários sobre distribuição geográfica, ecologia taxonomia das são apresentados.
Our motivation for writing this editorial is to alert the academic community about risks of predatory publishing in Biology. By piggy-backing on open access (OA) movement and taking advantage “publish or perish” culture a system that prioritises quantity over quality, has grown exponentially recent years spread across all areas knowledge. Thousands journals books have emerged (provided fee paid) they publish scientific papers chapters without submitting them rigorous peer review. Now there...
