Abstract Tropical dry forests are the most threatened tropical terrestrial ecosystem. However, few studies have been conducted on natural regeneration necessary to restore these forests. We reviewed ecology of as a tool disturbed lands. Dry characterized by relatively high number tree species with small, dry, wind‐dispersed seeds. Over small scales, seeds better able colonize degraded areas than vertebrate‐dispersed plants. Small and those low water content less susceptible desiccation,...
We review the ecological and socio-economic impacts of catastrophic dam failure in Mariana, Brazil. Tailing management practices by Samarco mining company ultimately caused a breach that abruptly discharged between 55 62 million m3 tailings into Doce River watershed. On November 5th, 2015, tsunami slurry engulfed small district Bento Rodrigues, loading its estuary with toxic along 663.2 km trajectory, extending to Atlantic coast. Acute will adversely affect livelihoods more than 1 people 41...
Phenology, floral biology, the reproductive system, and pollination of macauba palm, Acrocomia aculeata were studied in Central Brazil. The species is arborescent, single-stemmed, reaches heights up to 16 m. Flowering occurs between August December, peaking October November. Fruit fall (harvest) June March, with a peak Inflorescences are androgynous marked protogyny. basic syndrome by beetles, wind playing secondary role. principal pollinators Andranthobius sp. (Curculionidae), Mystrops cf...
1 The effects of fragmentation on quantitative measures floristic diversity in a palm community were examined the Biological Dynamics Forest Fragments study area central Amazonia. Three 1‐ha, three 10‐ha, two 100‐ha and continuous forest reserves, distributed among sites, surveyed. In each reserve, 10 20 × m plots sampled, resulting total 110 representing 4.4 sampled hectares. 2 taxon composition this was dominated by stemmed, understorey palms. A 23 225 individuals from 36 taxa recorded;...
Physical damage caused by litterfall is a source of seedling mortality that can be influenced environmental disturbances, such as the isolation forest fragments due to habitat destruction. The impact physical in was evaluated and continuous forests central Amazonia using artificial seedlings. A total 11 reserves distributed among three sites were studied: 1-ha, 10-ha, two 100-ha, reserves. In each reserve, ten transects comprised seedlings monitored for one year at four-week intervals....
Abstract The goal of restoration is to accelerate ecosystem recovery, but in ecosystems that naturally regenerate rapidly techniques need be selected carefully facilitate rather than impede natural recovery. We compared the effects five techniques, such as plowing soil, removing grasses, adding forest litter, seeding, and planting nursery‐growing seedlings, on regeneration seasonal deciduous trees four abandoned pastures central Brazil. monitored all woody stems immediately prior treatments...
In the middle of a political and fiscal crisis, Brazilian government is applying successive budget cuts, including in science funding. Recent cuts radically affect research programs on biodiversity that are crucial components for design monitoring public policies nature conservation sustainable development. We analyze consequences such Research Program Biodiversity (PPBio), largest network Brazil (626 researchers, nine networks all biomes). holds substantial part world's tropical forests...
Global sustainability rests on a myriad of benefits provided by natural ecosystems that support human livelihoods and well-being, from biodiversity persistence to climate regulation. The undeniable importance conserving tropical forests has drawn most the conservation spotlight towards it. However, open such as Brazilian Campo Rupestre (rupestrian grassland), have been historically overlooked despite their high diversity key associated ecosystem services. We highlight major current threats...
The effects of Brazil´s political crisis on biodiversity conservation are likely to be global. Brazil is not only the World´s most biodiverse nation, it responsible for greater part Amazon forest, which regulates climate and provides rain much southern South America. was a World leader in satellite monitoring land-use change, in-situ monitoring, reduction tropical-forest deforestation, protection indigenous lands, model other developing nations. Coordinated public responses will necessary...

Estimating the on-site and off-site impacts of soil erosion as a function land use climate conditions in semi-arid basins is key for water conservation strategies. However, research gap exists theme, requiring further investigation using local hydrological data. To accomplish it, SDR-InVEST model was applied to Pardo-FB basin (Brazil) different use, conservation, conditions. The mean annual loss sediment yield varied between 7 36 Mg ha−1 yr−1 1.2 52.2 Gg yr−1, respectively. areas where...
Fruit set, fruit production, and fall of the arborescent palm Acrocomia aculeata were documented for Distrito Federal in central Brazil 1984-1986. Flowering began August extended to mid-December with highest concentration open inflorescences (>50% total) occurring from mid-October until mid-November. There was a significant correlation (Spearman rank coefficient; r = 0.69; N 8; P 0.05) between flowering time set over course reproductive season. The that opened October those produced mean...
Seed dispersal, predation, desiccation and seedling survival are strong bottlenecks that impede tropical forest recovery on abandoned agricultural lands (reviewed in Holl 2002). The ability to resprout after disturbances overcomes these barriers, as those individuals bypass the seed stage have more vigorous shoots than seedlings (Bond & Midgley 2001, Kammesheidt 1999, Kennard et al. Resprouting is a particularly important mechanism dry forests Vieira Scariot 2006). There number of...
ABSTRACT We tested the relationship between length of pasture use and density, richness, composition naturally regenerating tropical seasonal deciduous forest in pastures. sampled trees 25 pastures distributed four age classes ranging from < 6 to 40 yr use. Density did not change with age, but richness was lower 25‐ 40‐yr‐old Nonetheless, a number species seem be able resprout even after ranching.

A bacia do rio Paranã (Goiás e Tocantins) com 5.940.382ha, tem alta diversidade de fitofisionomias, incluindo a floresta estacional decidual sobre afloramento calcário, que ainda não foi estudada nesta região. Este trabalho objetivou o levantamento quantitativo da vegetação arbórea uma calcário (13°49'34''S 46º 41'55''W; 478m altitude) na fazenda São José, Domingos, GO. Foram demarcadas cinco linhas intervalos 100m, onde foram aleatoriamente alocadas 25 parcelas permanentes 20 × 20m (1,0...
