Arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) associations are critical for host-tree performance. However, how correlate with the latitudinal tree beta-diversity remains untested. Using a global dataset of 45 forest plots representing 2,804,270 trees across 3840 species, we test AM EcM contribute to total its components (turnover nestedness) all trees. We find rather than predominantly decreasing turnover increasing nestedness latitude, probably because wide distributions do not...
Local factors can play an important role in defining tree species distributions rich tropical forests. To what extent the same applies to relatively small, poor West African montane forests is unknown. Here, survive a grassland matrix and fire has played key their spatial temporal dynamics since Miocene. these influence local distributions, as compared with other environmental variables such altitude moisture remain we use data from 20.28 ha forest plot Ngel Nyaki Forest Reserve, South-East...
Tree seedling dynamics underpin subsequent forest structure and diversity as different species/guilds respond variously to abiotic biotic stresses. Thus, understanding differential responses stresses helps us predict trajectories. Because forests vary in both environment species composition, generalisations across tropical are difficult. Afromontane important carbon stores, harbour high provide critical ecosystem services, yet they vulnerable climate change. Here, we investigate the...
Abstract The “hierarchy of factors” hypothesis states that decomposition rates are controlled primarily by climatic, followed biological and soil variables. Tropical montane forests (TMF) globally important ecosystems, yet there have been limited efforts to provide a biome‐scale characterization litter decomposition. We designed common experiment replicated in 23 tropical sites across the Americas, Asia, Africa combined these results with previous study lowland (TLF). Specifically, we...
The identification of flowering plants using DNA barcoding proposed in last decades has slowly gained ground Africa, where it been successfully used to elucidate the systematics and ecology several plant groups, understand their evolutionary history. Existing inferences on effectiveness identify African trees are mostly based lowland forests, whereas adjacent montane forests significantly differ from latter floristically structurally. Here, we tested efficiency chloroplast barcodes (rbcLa,...
Abstract Protected areas such as forest reserves are often assumed to be best ways conserve biodiversity and maintain intact ecosystems. We examined woody plant composition diversity in the gallery savannah woodland habitats of Amurum Forest Reserve immediately surrounding it Jos, Nigeria. A total 100 10 × m sample plots were established inside outside reserve. All plants ≥1 cm diameter at breast height (dbh) identified measured. 7,564 individual categorized 134 species from 44 families...
Abstract Questions A leading hypothesis for species coexistence in species‐rich, lowland tropical forests is conspecific negative density dependence (CNDD), driven by host‐specific pests and pathogens competition available resources. The extent to which this applies Afromontane with relatively low diversity, a high frequency of single‐species stands, few larger edge:core ratios, unknown. We hoped that the results our investigation would either confirm generality CNDD across these different...
Seed dispersal is fundamental to the resilience of plant communities and birds are important seed dispersers, contributing maintenance restoration community structures. In this study, we investigated contributions bird species in a woodland savanna Jos, Nigeria. dry season 2022, observed consuming fruits on 104 individual plants belonging 26 species. Five hundred six (506) 19 12 families were from focal plants. Bird trapping was conducted collect intact seeds fecal samples examine...
Abstract Predicting how forest species composition may change in response to global is essential for meaningful management. Which are most likely successfully recruit depends on a multitude of factors, but processes operating at the seed‐to‐seedling transition being especially important. Here, we explore insufficient seed dispersal (dispersal limitation) and ecological filtering seedlings (establishment influence recruitment an Afromontane Forest. We combined census data from seeds traps...
A preliminary study on the hygrophytic composition in Amurum Forest Reserve, Laminga Jos was undertaken September to December 2015 using seven (7) different sampling sites. total number of 57 species belonging 38 families were recorded as hygrophytes from river flowing through Forest. The division Angiosperms occurred most with 35 (25 families), followed by Pteridophyta 19 (11 families) while Bryophyta had 3 (3 families). Hygrophytes considerable all This report serves a foot print knowledge...
