Significance Tree diversity is fundamental for forest ecosystem stability and services. However, because of limited available data, estimates tree at large geographic domains still rely heavily on published lists species descriptions that are geographically uneven in coverage. These limitations have precluded efforts to generate a global perspective. Here, based ground-sourced database, we estimate the number biome, continental, scales. We estimated richness (≈73,300) ≈14% higher than...
Significance The responses of tropical forests to heat and drought are critical uncertainties in predicting the future impacts climate change. 2015–2016 El Niño Southern Oscillation (ENSO) resulted unprecedented low precipitation across tropics, including very poorly studied African forest region. We assess ENSO using on-the-ground measurements. Across 100 long-term plots, record high temperatures did not significantly reduce carbon gains from tree growth or increase losses mortality....
1 Comparative analyses of diversity variation among and between regions allow testing alternative explanatory models ideas. Here, we explore the relationships tree α-diversity small rain forest plots in Africa Amazonia climatic variables, to test power climate consistency two continents. 2 Our analysis included 1003 African 512 Amazonian plots. All are located old-growth primary non-flooded under 900 m altitude. Tree is estimated using Fisher's alpha calculated for trees with diameter at...
To provide an inter-continental overview of the floristics and biogeography drought-adapted tropical vegetation formations, we compiled a dataset inventory plots in South America (n=93), Africa (n=84), Asia (n=92) from savannas (subject to fire), seasonally dry 10 International Forestry Review Vol.17(S2), 2015 Floristics regions 11 forests (not generally subject moist (no fire).We analysed floristic similarity across formations within between continents.Our strongly suggests that different...
Abstract: We compare forests dominated by Gilbertiodendron dewevrei at the Dja Biosphere Reserve (Cameroon) with adjacent high-diversity mixed in terms of tree-species composition and stand structure, order to understand co-occurrence forest tree species monodominant forest. A total 18 1-ha permanent plots were established two types. In each plot, all trees dbh ≥10 cm identified as those <10 within a subsample 300 m 2 . Species richness was significantly different between Mixed had an...
