versatilidade. Neste trabalho, foram avaliados dados biometricos de G1111d11a weberbaueri (popularmente conhecido como taboca) que se desenvolveu em borda de tloresta (ambiente antropizado) e no interior da floresta. Valores de DAP (diametro na altura do peito) foram usados para calcular a biomassa de acordo com modelos especiticos para a especie e regiao. Observou-se que os tabocais que cresceram na borda obtiveram menores valores de biomassa em comparai;iio aos tabocais crescendo no interior da floresta. observando-se uma media de I, 76 kg vs: 4,59 kg p,,r individuo. respectivamente, o que mostra um efeito negativo do estresse abi6tico causado por di versos fatores antr6picos caracteristicos da borda da floresta (desmatamento, danos mednicos. eleitos do vento etc). Alem dos dados biometricos. este trabalho id correlacionar a biomassa com as caracteristicas ana16111icas Jos col mos e raizes de bambu de forma a entender como esses fatores de estresse abiotico interferem na anatomia do bambu.

Recently. the incidence of major allergic diseases has increased by the conversion of coniferous forests to deciduous broad-ka1·ed forest in Korea. Oaks such as Quercus serrata. Q. acutissima, and Q. mongulica. which are typical broad-leaved species of Korea, are allergen-inducing pollen species. Furthermore, identification of the dynamics between the flowering time and pollen dispersal under elevated CO, is very important in the establishment of health monitoring system. The present study aimed to assess bud development stages and pollen dispersal of Q. orniissi1110 according to elevated CO,. The pollen dispersal and production of oak species can be predicted by the interaction between temperature and other climatic factors as well as the complexity of overlapping plant seasonality. The pollen production increased in Q. acurissima grown under ekvated CO, compared with the atnll>spheric CO,. The pollen dispersal of Q. serrato tends to be different depending on the climatic factors, and the climate change due to the increase of CO, concentration is expected to increase the air pollen dispersal. Climate change and global warming are the main cause of plant phenology, but these phenologi�al patlerns can also affect by other factors including precipitation and CO, concentration. Plant phenological patterns are an imponant biomarker of ongoing ecosystem changes and can provide a general idea that future climate change can be a key driver of biodiversity changes.

In Brazil. most Eucalyptus plantations are located in regions experiencing periods of water shonage where fonilizers such as potassium (K) are intensively used to achiew high productivitv. Recently. sodium(, a) has also been considered a potential nutrient. As well as tree growth, 11·ood properties are also an important factor 10 consider in order to measure the impacts of silvicultural practices and water deficit on forest productivity, since they arc determinants for quality and yield of pulp and paper. In a split-plot experimental design with 4-year-olcl Lucal;ptus grand is trees, located in Sao Paulo State, Brazil, we evaluate the effects or Kand, a supply compared with a comrol treatment. under two water supply regimes (37% throughfall reduction versus no throughfall reduction) on stem volume, heanwood proportion. basic density, fiber, and vessel propenies. K and Na lenilization increased stem volume 2. 7 and 1.9 fold. respectively, with a non
significant effect of 37% throughfall reduction. Na fertilization was more detrimental to wood properties that K fenilization, affecting heanwood proponion, basic density, and fiber wall thickness. K fertilization affected only heartwood proportion and basic density. The 37% throughfall reduction only atfocted wood basic density. increasing it. Effects of fonilization treatments did not change regardless changes in water supply.Despite the detrimental effects of fenilizers (stronger with , a supplv) in wood properties there is a large beneficial effect on stem volume (stronger with K supply), even under a water availabil iry reduction, that would be compensates the loss of wood quality for pulp and paper production.

The large Brazilian urban centers are located in the Atlantic Rainforest domain, an impo11an1 glc,bal biome. and urban air pollution contributes to forest decline.
In the lpatinga's citv, Minas Gerais- Brazil. exist a steel mill and a circulating fleet of vehicles responsible for atmospheric pollutants emissions that contribute to the reduction of environmental quality. The objective was to evaluate the urban and industrial air pollution effects of lpatinga in Joannesia princeps Veil.
(Euphorbiaceae), a native Atlantic Rainforest specie. For this, we analyzed the visual foliar damages and the anatomical and micromorphological effects in extraftoral nectaries (EFNs) or this species. During 126 Jays. J. princeps seedlings wereexposed in stand systemsat Bom Retiro, Carin1. Cidade Nobre and Veneza points in the lpatinga's city. The leaf svmptomatology was evaluated monthly. For the anatomical analysis, EF1 s were collected and processed for analysis in light microscopy and scanning electron microscopy. At Born Retiro and Cariru points. the highest concentrations of NO. NOX. S02. OJ. benzene and naphthalene were recorded. The highest concentrations of hydnKarbon pollutants were recorded in the Cidade obre and Veneza points. In plants exposed at the Cariru point, more visual damage was observed. Regarding the anatomical and micromorphological damages in the EF s. tissue necrosis,wound healing formation and cdl hvperplasia, intense superficial damage such as epidermal rupture. fungal colonization, disarrangement and trichome fall were observed.
Thus. our data suggest that the urban air pollution or lpatinga's citypromotes changes in the morphology and micromorphology of native plant species.
