Abstract Plant traits – the morphological, anatomical, physiological, biochemical and phenological characteristics of plants their organs determine how primary producers respond to environmental factors, affect other trophic levels, influence ecosystem processes services provide a link from species richness functional diversity. Trait data thus represent raw material for wide range research evolutionary biology, community ecology biogeography. Here we present global database initiative named...
Tropical secondary forests recover quickly (decades) in tree species richness but slowly (centuries) composition.
The search for predictions of species diversity across environmental gradients has challenged ecologists decades. humped-back model (HBM) suggests that plant peaks at intermediate productivity; low productivity few can tolerate the stresses, and high a highly competitive dominate. Over time HBM become increasingly controversial, recent studies claim to have refuted it. Here, by using data from coordinated surveys conducted throughout grasslands worldwide comprising wide range site...
Tropical forests disappear rapidly because of deforestation, yet they have the potential to regrow naturally on abandoned lands. We analyze how 12 forest attributes recover during secondary succession and their recovery is interrelated using 77 sites across tropics. are highly resilient low-intensity land use; after 20 years, attain 78% (33 100%) old-growth values. Recovery 90% values fastest for soil (<1 decade) plant functioning (<2.5 decades), intermediate structure species diversity (2.5...
Abstract In the past decades, Brazil made important progress in conservation of forest ecosystems. Non‐forest ecosystems ( NFE ), contrast, have been neglected, even though they cover large parts country and biodiversity levels comparable to forests. To avoid losing much its ecosystem services, sustainable land use policies need be extended . A strategy for Brazil's should encompass following elements: (1) creation new protected areas ; (2) enforcement legal restrictions use; (3) extension...
Abstract Questions Functional redundancy in assemblages may insure ecosystem processes after perturbation potentially causing temporary or permanent local species extinctions. Yet, functional has only been inferred by indirect evidence measured methods that not be the most appropriate. Here, we apply an existing method to measure redundancy, which is fraction of diversity expressed diversity, assess whether affects community resilience disturbance. Location Subtropical grassland, south B...
Abstract Including ecosystem functions into restoration ecology has been repeatedly suggested, yet there is limited evidence that this taking place without bias to certain habitats, species, or functions. We reviewed the inclusion of in and potential relations habitats species by extracting 224 publications from literature (2004–2013). Most studies investigated forests, fewer grasslands freshwaters, fewest wetlands marine habitats. Of all studies, 14% analyzed only functions, 44% considered...
Significance Tropical forests disappear rapidly through deforestation but also have the potential to regrow naturally a process called secondary succession. To advance successional theory, it is essential understand how these and their assembly vary across broad spatial scales. We do so by synthesizing continental-scale patterns in succession using functional trait approach. show that start pathway of varies with climatic water availability. In dry forests, driven drought tolerance traits...
Abstract Question: How does fire influence species richness and diversity in subtropical grassland southern Brazil? Location: Recurrently burned Porto Alegre, Brazil (30°03′S, 51°07’W; max. altitude 311 m a.s.l.) abandoned near São Francisco de Paula, (29°47′S, 50°22’W; ca. 900 a.s.l.). Methods: In the grassland, between‐year changes community composition single‐plot diversity, number vegetation structure were analysed two consecutive years for plots with different time since last fire....

Abstract Questions What are the main short‐term changes in vegetation structure after fire and mowing Campos grasslands? Are there differences functional group responses between sites with diverse histories different treatments (fire mowing)? Location Subtropical grasslands P orto A legre, B razil, 30 °03′ S, 51 °07′ W. Methods In two histories: FB – frequently burned E exclusion of for 6 yr, seven pairs plots were examined. each pair, established. Bare soil litter cover estimated....
The Brazilian Atlantic Forest (BAF) is a global biodiversity hotspot, but its carbon sink capacity, especially in the subtropical portion, poorly understood. We aimed to evaluate relationship between measures (i.e., taxonomic, functional, and phylogenetic diversity) net change across BAF, testing whether there win–win situation conservation of capacity forests distinct ages. obtained from 55 permanent plots, early successional old-growth forests, by combining gains losses two censuses. found...
