Inde ed, perched bats count and excrement collection under daily dormitory have been performed with the purpose to evaluate E. helvum population size and dynamism (population variation) as well as to determine and/or discriminate the factors inducing that dynamism. E. helvum population in above mentioned experimental site, in relation to analyzed period (from August 2007 to July 2008) was estimated to 181384 ± 15013.26. Further, findings of present study suggested an increase in E. helvum population size from August to November, stabilization from November to February and reduction from March to July 2008. In addition, this study exhibited both food diversity (r=0.94; p ˂ 0.0001) and abundance (r=0.90; p ˂ 0.0001) as preponderant features influencing analyzed E. helvum population fluctuations. Food sources analysis revealed that E. helvum consumed Ficus exasperata Vahl (Moraceae) (r = 0.89; p < 0.0001), F. lutea Vahl (r = 0.86; p < 0,001) and F. polita (r=0.61; p< 0.05) as main food resources. In conclusion findings of present study evoked that season and as well both food diversity and abundance are significant parameters (p-value<0.05) which influenced E. helvum bats specie population dynamism. * Corresponding author KEYWORDS Straw-colored fruit bats Dynamic of the population Season effect Main food resources Côte d’Ivoire E-mail: dgnoel7@gmail.com, noel.dago@upgc.edu.ci (Dago Dougba Noël) Peer review under responsibility of Journal of Experimental Biology and Agricultural Sciences.
