Nessa região há o encontro do limite Sul do Cerrado e do limite Norte dos Campos Sulinos, além da Floresta com Araucária e a Floresta Estacional Semidecidual, gerando mosaicos de distintas fisionomias vegetais. Análises palinológicas e modelos de predição de vegetação em grande escala indicam uma tendência das florestas expandirem sobre os campos nessa região. Tal expansão pode se dar pelas bordas florestais ou pela colonização de espécies florestais sobre a matriz campestre. Nesta ocupação dos campos, as espécies florestais sofrem grande estresse, o qual pode ser atenuado pelo sombreamento promovido por plantas isoladas - nurse plants - num processo chamado facilitação. No presente estudo avaliamos a facilitação por espécies lenhosas na expansão florestal sobre campos, em uma região de ecótono entre Campo Sulino, associado à Floresta com Araucária e Cerrado, no Sul do Brasil. Compa...

Defesa: Curitiba, 21/02/2017Referências ao final de cada capituloÁrea de concentração : Ecologia e conservaçãoResumo: O bioma Floresta Atlântica, um hotspot de biodiversidade, abriga a maior parte das terras cultivadas e da população do Brasil. Encontrar um caminho sustentável para o uso da terra nesse bioma é necessário, dado que as condições regionais e globais do clima, a provisão de comida e energia e a conservação da biodiversidade, estão todos em jogo. Aplicações da teoria ecológica podem auxiliar nesse objetivo de se atingir o desenvolvimento sustentável, conciliando produção e conservação da Floresta Atlântica. Essa tese teve como objetivo geral verificar o padrão de distribuição espacial da diversidade de espécies lenhosas em remanescentes da Floresta Atlântica e relacionar com indicadores de produ...

When land-use patterns are not maximally efficient relative to productivity, provisioning services, such as crop production, can often be increased without losing biodiversity. The Atlantic Forest (AF) encompasses dense, mixed, and seasonal forests and has high levels of endemism and anthropogenic threat. We examined trade-offs between biodiversity and crop production in the AF to provide insights into land-use management decisions. We developed a biodiversity metric that combines information on tree species richness, evolutionary distinctiveness, and rarity at the local level. We examined the extent to which the nature of ES trade-offs differ among the 3 forest types. We assessed how annual deforestation rates and land management practices affect biodiversity and agricultural revenues. Finally, we tested whether it is possible to ach...

Location: South America, Brazilian Atlantic Forest. We compiled the occurrence of 2,071 woody plants in 177 sites across the Brazilian AF. We assessed the elements of metacommunity structure (species coherence, turnover and boundary clumping) to identify which idealized structure (checkerboard, nestedness, Clementsian, Gleasonian, evenly spaced or random) characterizes the AF and its forest types. We used the additive partition of diversity to determine the main spatial scales promoting biodiversity in the AF, that is local (within sites, α-diversity), regional (among sites in each forest type, β1) or geographical (between forest types, β2), and examined environmental variables driving the metacommunity of the AF and forest types using canonical ordinations. The AF and its forest types presented positive coherence, negative turnover and large boundary clumping values which best-fit the nested subsets metacommunity structure with clumped species loss. The diversity within sites (α-diversity) and among types (β2) was higher than expected by chance. The climatic gradient driving the species composition differed in the AF. Temperature variation affected the entire AF, particularly Dense and Seasonal forests, whereas precipitation affected mostly the Mixed forest. Main conclusions: Despite the similar structure underlying AF metacommunities, the main environmental gradient in each forest differs, highlighting ecological differences among communities at geographical scale. These differences are determinant for the high levels of biodiversity found in the AF. Conservation efforts should encompass all the AF ecosystems, considering its unique characteristics and prioritizing species-rich sites given that they adequately represent the regional species pool.

Three main forest types, differentiated by their floras, compose the Atlantic Forest: 'Atlantic Forest' sensu strictu, 'Araucaria Mixed Forest' and 'Seasonal Forest'. The flora comprises taxa from the Amazon forest, Cerrado gallery forests and the Andean region, which makes the Atlantic Forest a relevant study system for ecologists and biogeographers. Here, we present data from 206 floristic checklists describing the occurrence of 1,916 species across the southern portion of the Atlantic Forest. This dataset can be useful for understanding mechanisms underlying plant community assembly processes and the historical relationships between different forest formations.

The study on interspecific variation in plant traits has generated important insights into the life-history strategies and their consequences for ecosystem functioning. However, it remains unknown to what extent – and even if – species’ functional traits are related to the variation in their growth trajectories. We set out to model growth trajectories of 45 woody species from the Brazilian Atlantic Forest in a secondary subtropical forest under regeneration, aiming to understand if species can be grouped by their growth patterns throughout ontogeny and if these groups could be classified in distinct ecological strategies based on key plant traits. We used a maximum likelihood estimation approach to predict growth trajectories using three ecologically relevant parameters [maximum growth rate (Gmax), diameter at maximum growth rate (Dopt), and the ontogenetic variability in growth rate (K)] foll...
