Seed dispersal by a guild of mammalian herbivores in Qatrouiyeh National Park Hasan Mahmoudi h mahmoudi@na iut ac ir Date of Submission 2014 1 24 Department of Natural Recourcese Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Mahmoudreza Hemami Mrhemami@cc iut ac irAbstract Seed dispersal is one of the important factors influencing the spatial distribution and dynamics ofplant communities It can have impacts on many key aspects of plant ecology includingregeneration and species diversity and species invasion and movements across space and time Seed dispersal is particularly important in arid ecosystems for the dynamics of vegetation In theseareas many species produce seeds to regenerate through sexual reproduction hence seed dispersalfrom distant seed sources by herbivores can play a significant role in the dynamics and persistenceof vegetation communities In this study the potential for seed dispersal through endozoochory bynative herbivores including Persian wild ass or onager Equus hemionus wild goat Capraaegagrus wild sheep Ovies orientalis and Jebeer gazelle Gazella bennettii of Qatrouiyeh NationalPark were studied Dung samples were collected from main habitats of each species across thestudy area in three seasons spring summer and fall For onager a total of 90 samples and for eachof wild goat wild sheep and jebeer gazelle 40 samples were collected in each season Dungsamples were cultivated in a green house For onager a total of 43 plant species 20 16 and 36species from August December and June samples respectively from 30 genus and 16 familiesgerminated from dung samples For wild got a total of 28 plant species 21 12 and 14 species fromAugust December and June samples respectively from 24 genus and 12 families germinated fromdung samples For wild sheep a total of 34 plant species 17 13 and 24 species from August December and June samples respectively from 27 genus and 13 families germinated from dungsamples For jebeer gazelle a total of 22 plant species 14 9 and 11 species from August Decemberand June samples respectively from 18 genus and11families germinated from dung samples Lepidium vesicarium Brassicaceae Astragalus podolobus Fabaceae and Cynodon dactylon Poaceae were the most abundant plant species germinated from August December and Junesamples respectively Forbs were the most abundant vegetative form germinated from the dung ofthe four herbivore species Significant differences between seed composition of all herbivores wasobtained through a DCA analysis Jaccard similarity index was highest between plant speciesgerminated from dung of jebeer gazelle and wild got and was lowest between jebeer gazelle andonager Keywords Endozoochory huge herbivores Nich arid ecosystems germination
