Forest Biome

The Atlantic Forest biome is a biodiversity hotspot with only 13% of its native vegetation cover remaining in Brazil. Forest restoration is an important process for the re-establishment of biodiversity and the preservation of water resources in degraded areas, like riparian forests. Monitoring is an essential step of restoration, because the periodic evaluation of indicators allows researchers to analyze the effectiveness of applied techniques. This study aimed to evaluate the environmental quality of a seedling planting (active restoration) in a Permanent Preservation Area (PPA) of the Southeast Atlantic Forest biome, through a monitoring protocol, within a year. More specifically, we aimed to investigate the following questions: (1) do some ecological groups or families grow more than others? and (2) is the cover of exotic grasses negatively influencing forest regeneration? Data were collected during November 2017 and April (interval represents five months of wet season) and October 2018 (six months of dry season). Eight plots of 9 × 18 m were established and all individuals were identified and measured (diameter at ground level (DGL), height (H), and canopy diameter (CD)). Exotic grass cover and richness of regenerating species were also recorded. We registered 119 individuals during the three inventories, distributed in 35 species and 14 families. Results indicate an inverse association between exotic grasses and the presence of recruits in the area. Thus, exotic grass control may be needed while the forest canopy is not closed. A significant growth of individuals in the whole study period, especially during the wet season, was detected. Legumes grew more in trunk and canopy diameter (Anadenanthera colubrina (Vell.) Brenan and Inga vera Willd. subsp. affinis (DC.) T. D. Penn. had the biggest growth, respectively) than non-legumes during wetter months and within a year. Pioneers had greater height increase compared to non-pioneers only during wetter months. Legumes may be important species to be used in other young tropical forest restoration areas.

Restoration of Atlantic Forests is receiving increasing attention because of its role in both biodiversity conservation and carbon sequestration for global climate change mitigation. This study was carried out in an Atlantic Forest restoration project in the south-central region of São Paulo State - Brazil to develop allometric equations to estimate tree biomass of indigenous tree species in mixed plantations. Above and below-ground biomass (AGB and BGB, respectively), stem diameter (DBH: diameter at 1.3 m height), tree height (H: total height) and specific wood density (WD) were measured for 60 trees of 19 species. Different biomass equations (linear and nonlinear-transformed) were adjusted to estimate AGB and BGB as a function of DBH, H and WD. For estimating AGB and BGB, the linear biomass equation models were the least accurate. The transformed nonlinear biomass equation that used log DBH2, log H and log WD as predictor variables were the most accurate for AGB and the transformed nonlinear biomass equations that used log DBH2*WD as predictor variables were the most accurate for BGB. It is concluded that these adjusted equations can be used to estimate the AGB and BGB in areas of the studied project. The adjusted equations can be recommended for use elsewhere in the region for forest stands of similar age, tree size ranges, species composition and site characteristics.

O objetivo deste trabalho foi avaliar a diversidade de espécies florestais nativas produzidas nos viveiros do estado do Rio de Janeiro. O levantamento e diagnóstico foram realizados durante os meses de fevereiro, março e abril de 2010, sendo incluídos os viveiros que produziam mudas de espécies florestais da Mata Atlântica. O trabalho de campo consistiu em visitas a 70 viveiros florestais, nos quais foi requerida a lista das espécies produzidas e realizada entrevista com o responsável, sendo preenchido um questionário englobando diversos temas relacionados à produção de mudas. Foram observadas 277 espécies florestais nativas da Mata Atlântica sendo produzidas nos viveiros, que, em média, trabalham com 56 espécies nativas. A diversidade total de espécies florestais da Mata Atlântica produzidas nos viveiros do Estado do Rio de Janeiro é baixa, assim como a diversidade média, já que mais da metade dos viveiros trabalha com uma listagem de 50 ou menos espécies, número insuficiente considerando a diversidade de espécies florestais presentes nas diferentes formações vegetais do estado.Palavras-chave: Mudas florestais; restauração florestal; Mata Atlântica. AbstractAssessment of diversity of native species produced in forest nurseries of Rio de Janeiro State. The objective of this paper was to evaluate the diversity of native species produced by nurseries in the State of Rio de Janeiro. The diagnostic and survey were conducted during the months of February, March and April of the year 2010, the research included all nurseries that produced seedlings of Atlantic Forest species. The fieldwork consisted of visits to the 70 surveyed nurseries, in which a list of the species produced in the nursery was requested and the seedling production manager was interviewed, filling in a questionnaire covering various topics related to seedlings production. We observed 277 forest species native from the Atlantic Forest produced in the nurseries. In average, the nurseries produce 56 different native species. The total diversity of native species produced in the State of Rio de Janeiro is low, as well as the mean diversity, since more than half of the nurseries work with a list of 50 or fewer species, what is insufficient considering the diversity of forest species that occur in the different vegetation types of the state.Keywords: Forest seedlings; forest restoration; Atlantic Forest.

We report data related to arbovirus antibodies detected in wild birds periodically captured from January 1978 to December 1990 in the counties of Salesópolis (Casa Grande Station), Itapetininga and Ribeira Valley, considering the different capture environments. Plasmas were examined using hemagglutination-inhibition (HI) tests. Only monotypic reactions were considered, except for two heterotypic reactions in which a significant difference in titer was observed for a determined virus of the same antigenic group. Among a total of 39,911 birds, 269 birds (0.7%) belonging to 66 species and 22 families were found to have a monotypic reaction for Eastern equine encephalitis (EEE), Venezuelan equine encephalitis (VEE), Western equine encephalitis (WEE), Ilheus (ILH), Rocio (ROC), St. Louis encephalitis (SLE), SP An 71686, or Caraparu (CAR) viruses. Analysis of the data provided information of epidemiologic interest with respect to these agents. Birds with positive serology were distributed among different habitats, with a predominance of unforested habitats. The greatest diversity of positive reactions was observed among species which concentrate in culture fields.

<p>The aim of this study was to investigate how the spatial distribution of grass influenced run-off and erosion from a hillslope with loess and cinnamon soils in the rocky area of Northern China. We set up a trial to test the two soils with different treatments, including bare soil (BS), grass strips on the upper (UGS) and lower (DGS) parts of the slope, grass cover over the entire slope (GS), and a grass carpet on the lower part of the slope (GC), under simulated rainfall conditions. The results showed that the run-off coefficients for the loess and cinnamon soils decreased by between 4% and 20% and by between 2% and 37%, respectively, when covered with grass. Grass spatial distribution had little effect on the run-off, but more effect on erosion than vegetation coverage degree. The most effective location of grass cover for decreasing hillslope erosion was at the foot, and the high efficiency was mainly due to controlling of rill formation and sediment deposition. The soil loss from GS, DGS, and GC on the loess and cinnamon soils was between 77% and 93% less and 55% and 80% less, respectively, compared with the loss from BS. However, the soil characteristics had little effect on soil erosion for well-vegetated slopes. The results highlight the importance of vegetation re-establishment at the foot of hillslope in controlling soil erosion.</p>
