“…The distribution was positively associated with sandy soil texture and acidic soil (pH≤4.5) and negatively associated with clay soil (Table 1). These findings were consistent with the species' distribution in the DDF, with its fertile soils (Teejuntuk, 2003;Sahunalu, 2009;Ueda et al, 2017) . This species group can shift to higher elevation as drought or low SMC increase with climate change (Marod et al, 2002;Sahunalu, 2009;Trisurat et al, 2009).…”

“…The environmental factors responsible for plant distribution can vary in the FE located between lowland and upland forest (Tang and Ohsawa, 1997), especially the topographic and climatic factors (Martin et al, 2007). In addition, soil properties in this area also vary due to the soil parent material, which is related to topographical and geological gradients (Rhodes et al, 2005;Weill and Munkholm, 2015) or vegetation cover (Ueda et al, 2017) . Deciduous and evergreen species coexist in the FE located at altitudes between deciduous dipterocarp forest (DDF) and lower montane forest (LMF) (Marod et al, 2015).…”

Plants' ecological niches are important to study, particularly for applying the knowledge to restoration programs. This study clarified the relationships of tree species composition and spatial distribution to environmental factors in a mountain ecosystem. A 3 ha permanent plot was established across the forest ecotone at Doi Suthep-Pui National Park, Chiang Mai Province, Thailand. The spatial distributions of the 20 dominant tree species were analyzed using a generalized linear model (GLM) combined with geographic information system (GIS) techniques. High species diversity was found, including 165 species representing 118 genera and 59 families. Elevation strongly influenced tree distribution, which could be divided into three groups: low-altitude species in deciduous dipterocarp forest (DDF), highaltitude species in lower montane forest (LMF) and coexisting DDF and LMF species. The GLM analysis revealed that soil texture, which ranged from sandy to clayey, influenced tree distribution. The results suggest that restoration programs should select suitable species based on their niches.

“…For SDZ stress, four tested soils PNR responses were not consistent. This could be related to the difference in soil properties [25]. Besides, it was worth noting that a good dose-response curve of SDZ and soil PNR was only found for desert and brown soil, which indicated the nitrifying microorganisms of paddy and black soil were not sensitive to SDZ contamination.…”

To investigate responses difference of soil potential nitrification rates (PNR) to heavy metals and antibiotics, batch toxicity experiments of Cu and sulfadiazine (SDZ) were conducted in four typical soils which were collected from different locations of China. Toxic differences of Cu and SDZ to soil PNR were evaluated based on their values of EC 20 and EC 50 calculated with logistic model. It was found that soil nitrification was a good indicator of Cu contamination in soils except for paddy soil. For SDZ, their EC X values were significantly higher than its concentration level (0.002~0.760 mg·kg -1 ) in soils. Thus, it was concluded that soil nitrification might be more sensitive to Cu than SDZ in field soil. The further Pearson correlation analysis indicated that the response of soil PNR to Cu and SDZ contamination were significantly related with soil PNR 0 and pH. ARTICLE HISTORY

“…O desenvolvimento da espécie nos primeiros anos é superior nos espaçamentos reduzidos (Lopes et al, 2017), porém com o passar dos anos, a maior competição por luz, nutrientes (Ghezehei et al, 2015) e menor taxa de mortalidade (Schumacher et al, 2011), faz com que os espaçamentos mais amplos consigam obter produtividades (Silva et al, 2016) e estocagem de carbono similares. O crescimento e maior volume de madeira das plantas tem relação direta com a estocagem de carbono, e são afetadas por fatores como qualidade do solo (Ueda et al, 2017), competição por luz (Coonen & Sillett, 2015), resistência a seca (Hänke et al, 2016), temperatura do local (Chen et al, 2017) e a susceptibilidade a pragas e doenças (Bett et al, 2016).…”

As plantações de eucalipto podem compensar as emissões de gases com efeito estufa (GEE) das atividades de fertilização e plantio, devido à capacidade das árvores em armazenar carbono na forma de biomassa. O objetivo deste estudo foi estimar o sequestro de carbono em plantações de eucalipto com diferentes densidades de instalação. O estudo foi conduzido no município de Lamim, no estado de Minas Gerais - Brasil, numa plantação de eucalipto dividida em quatro áreas de 0,25 ha com diferentes densidades de instalação. O diâmetro à altura do peito e altura total dos indivíduos foram obtidos por inventário florestal. A biomassa foi calculada pela multiplicação do volume e densidade básica da madeira. As emissões de GEE foram calculadas a partir dos dados de fertilização e calagem. O reservatório de carbono (90,94 MgCO2eq ha-1) e as emissões de GEE foram superiores no espaçamento de 2 x 1 m. A menor emissão de GEE por m3 de madeira produzido foi no espaçamento 2 x 2 m. O balanço de carbono foi positivo em todos os espaçamentos avaliados. Foi possível concluir que as florestas de Eucalipto são capazes de compensar as emissões de GEE da fertilização nitrogenada e calagem em plantações pouco tecnificadas.
