| 2 | Tree-based ecosystem services supply and multifunctionality of church forests and their agricultural matrix near Lake Tana,Ethiopia显示文摘Ecosystem services(ES)are the connection between nature and society,and are essential for the well-being of local communities that depend on them.In Ethiopia,church forests and the surrounding agricultural matrix supply numerous ES.However,the ES delivered by both land use types have not yet been assessed simultaneously.Here we surveyed both church forests and their agricultural matrices,aiming to quantify,compare and unravel the drivers underlying tree-based ES supply,density and multifunctionality.We found that almost all church forests and half of the agricultural matrices provided high ES densities.ES multifunctionality was higher in the agricultural matrices,suggesting that people deliberately conserve or plant multifunctional tree species.Furthermore,the supply of all categories of ES was positively correlated with church forest age(p-value<0.001)in the agricultural matrix,while the extent of church forest was positively correlated with the density of all categories ecosystem services score in the church forests(p-value<0.001).Our results can be used to prioritize conservation efforts at sites that provide high levels of ES supply,ES density and ES multifunctionality,and to prioritize restoration efforts at sites with low levels thereof. | Ferehiwot Mequanint Tobias Fremout Diederik Strubbe Alemayehu Wassie Shimelis Aynalem Enyew Adgo Jan Nyssen Amaury Frankl Luc Lens Bart Muys | 2023 | Forest Ecosystems2023，10，6： | 0 |
| 3 | Effects of land use on the fungal spore richness in small crater-lake basins of western Uganda显示文摘Mycological tools to estimate the effects of diverse land-use practices on fungal diversity are scarce,because of poor knowledge of the taxonomic diversity of tropical fungi and their response to anthropogenic habitat change.Here,we investigate assemblages of fungal spores,recently deposited in the bottom sediments of 24 small crater lakes in western Uganda,to assess the relationship between the local richness of fungi and environmental variation in the crater basin along regional gradients of natural vegetation and land use.We recovered~9500 fungal spore specimens,which could be attributed to 216 morphotypes.Using an information-theoretic approach based on the corrected Akaike Information Criterion(AICc),we determined the environmental factors which best explained variation in the diversity of fungal spores among three datasets:(i)the full set of 24 crater basins,(ii)the subset of 22 basins with freshwater lakes,and(iii)the subset of 17 basins partly or completely in agricultural use(cropland,fallow land,pasture and plantation).In these 17 human-impacted crater basins our results revealed a negative relationship between fungal spore richness and the areal fraction of basins in agricultural use.However,this detrimental effect of land use on fungal spore richness was not apparent across the full set of both disturbed and(presently)undisturbed basins.This was due to large variation in fungal spore richness among the undisturbed basins covered either with forest or savannah vegetation,probably resulting from site-specific controls on fungal habitat diversity,such as climatic moisture balance and the composition of natural and/or secondary vegetation.The land-use effects on fungal spore diversity,as documented in this study,suggest that communities of tropical fungi progressively exposed to land-use practices are threatened by species loss.Hence,our study demonstrates the need to develop conservation strategies mitigating the impacts of agriculture on the biodiversity of tropical fungi. | Vanessa Gelorini Annemieke Verbeken Luc Lens Hilde Eggermont Bent Vad Odgaard Dirk Verschuren | 2012 | Fungal Diversity2012，，4： | 0 |
