Abstract

Testing how local environmental conditions influence plant community assembly is important to understand the underlying mechanisms that promote and/or maintain biodiversity. Functional traits are used to find the broad spectrum of resource use strategies that plants use to respond to environmental variation. The patterns and drivers of plant community assembly through the lens of traits and phylogeny; however, remain to be studied in a uniquely biodiversity rich but poorly known fragmented dry Afromontane forest of Ethiopia. Here, we combined trait and community phylogenetic data from thirty sampling plots of 20 x 20 m size to determine the functional and phylogenetic structures and their drivers in a fragmented, human-dominated dry evergreen Afromontane forest. We found phylogenetic and functional clustering of plants in which the effect of environment was found to be trait specific. A weak phylogenetic signal for traits was detected suggesting that species resource use strategies may not be inferred using species phylogenetic distance. Additionally, we found functional traits to be weak in predicting species abundance distribution. Overall, while this study shows a non-random community assembly pattern, it also highlights the importance of deterministic processes being trait specific.Abstract in Amharic is available with online material. ብዝሃ-ህይወት የሚጠብቁትን መሰረታዊ ስልቶች ለመረዳት፣ የአካባቢ ሁኔታዎች በእጽዋት ስርጭት ላይ እንዴት ተጽዕኖ እንደሚያሳድሩ ማጥናት አስፈላጊ ነው። ዘርፈ-ብዙ የሆነውን የእጽዋትንና አካባቢን መስተጋብር ለመረዳት የእጽዋቶች ባህሪያት (functional traits) ይጠቅማሉ:: በተራቆተው ነገር ግን በብዝሃ-ሂዎቱ በሚታወቀው በሰሜኑ የአትዮጵያ ክፍል የሚገኘው ደን የእጽዋት ስርጭትና ስርጭቱን የሚቆጣጠሩ ደንቢውች አልተጠኑም:: በዚህ ክፉኛ በተራቆተ አካባቢ ውስጥ በሚገኘው ደን እያንዳንዳቸው 20 x 20 ሜትር መጠን ባላቸው ሠላሳ የናሙና ቦታዎች በመውሰድ የደኑን ባህሪያት (functional traits) እና ዝምድና (phylogenetic relationships) መረጃ በመሰብሰብ, የ a5;ጽዋቶችን የቦታ አመራረጥና የደንቢወችን ተፅዕኖ አጥንተናል:: በጥናቱም የእጽዋቶችን ባህሪያት (functional traits) እና ዝምድና (phylogeny) ስርጭት በዘፈቀደ ሳይሆን ስልታዊ በሆነ ተመሳሳይ ፍላጎት ባላቸው እጽዋቶች መሰባሰብ ነው(clustering):: ነገር ግን የአካባቢው አፈር ተፅዕኖ በሁሉም የእጽዋት ባህሪያት (functional traits) ሳይሆን በተወሰኑ ብቻ ነው:: በተጨማሪም የእጽዋቶች አመጋገብ ስርዓት (resource use strategies) በመካከላቸው ባለው ዝምድና አይወሰንም:: ሩቅ ዝምድና ያላቸው እጽዋቶች ተመሳሳይ የአመጋገብ ፍላጎትና ስልት ሊኖራቸው ይችላል::ከዚህም በተጨማሪ የእጽዋቶች ባህሪያት (functional traits) የእጽዋቶችን የብዛት ስርጭት (Species abundance distribution) የመወሰን አቅማችው ደካማ ሆኖ ተገኝħ 7;ል::ባጠቃላይ ይህ ጥናት እጽዋቶች በዘፈቀደ ሳይሆን የተሰራጩት (random distribution)፣ የኣካባቢውን ሃብት (resource) መሰረት አድርገው መሆኑን አሳይቷል:: በተጨማሪም የአካባቢው ደንቢ ሁሉንም ባህሪያት(functional traits) እኩል ተፅዕኖ አላደረገም፣ ይልቁንም ባህሪያትን (traits) መሰረት ያደረገ ነው:: While trait and phylogenetic convergence of plant communities with trait-specific response to environmental factors was detected, traits were found to be weak in predicting species abundance distribution in a fragmented forest.image
