- Abstract: Fruit‐eating animals play important roles as seed dispersal agents in terrestrial systems. Yet, the extent to which seed dispersal by nocturnal omnivores may facilitate germination and the recruitment of plant communities has rarely been investigated. Characterizing their roles in seed dispersal is necessary to provide a more complete picture of how seed dispersal processes affect ecosystem functioning. We investigated the roles and impacts of two species of nocturnal omnivorous lemur species, Microcebus jollyae and M. rufus, on seed dispersal in Madagascar's rain forests, through analysis of fecal samples and germination experiments. Data show that these lemur species, which are among the world's smallest primates, dispersed 22 plant species from various forest strata and that the defecated seeds germinated faster and at higher rates than control seeds for the eight plant species we tested. Even though mouse lemurs dispersed both native and non‐native plant species, non‐native plant species represented a relatively small proportion (17%). These results demonstrate that overlooked nocturnal omnivores can act as important seed dispersers, which may have critical implications for forest regeneration and the maintenance of plant diversity in fragmented/degraded forests. Finally, we provide critical insights into the previously unobserved behavior and diet of endangered nocturnal lemurs for their effective conservation.

Vitsy anefa ny fikarohana ifotony mahakasika ny anjara asan'ny biby mivelona amin'ny karazan‐tsakafo maro eo amin'ny fanamorana ny fitsirin'ny vihy sy ny fitoeran'ny zavamaniry eo amin'ny tontolo misy azy. Kanefa, mety hameno ny fahalalana sy fahazoana ny fiatraikan'ny fanapariaham‐bihy ataon'ny biby eo amin'ny fomba firafitra sy fiasan'ny ala izany. Nandalina ny fanapariaham‐bihy ataona karazam‐barika roa mpivoaka alina sy mivelona amin'ny karazan‐tsakafo maro ( Microcebus jollyae sy Microcebus rufus na antsidy) ao anatin'ny ala mando Malagasy izahay. Izany dia natao tamin'ny alalan'ny fanangonana sy famantarana ireo karazan‐java‐maniry izay mety ho haparitany amin'ny alalan'ny tainy, ary ny fambolena ireo vihy voaangona ireo. Hita ary fa ireo antsidy roa ireo, izay anisan'ny varika kely indrindra eran‐trany, dia manaparitaka vihy avy amina karanzan‐java‐maniry 22 avy amin'ny ambaratongan'ala samihafa. Nitsimoka malaky kokoa ireo vihy avy amina kazaran‐javamaniry valo tao anatin'ny tain'izy ireo raha mitaha amin'ireo vihy izay nalaina tao anatin'ny voankazo matoy. Nahitana vihin‐java‐maniry tsy zanatany ihany koa tao anatin'ny tain'ireo antsidy ireo, izay kely ihany (17%) raha mitaha amin'ny isan'ny karanzan‐java‐maniry zanatany voaisa. Ireto vokam‐pikarohana ireto dia mampiseho sy manasongadina fa mpanaparitaka vihy mahomby ny biby mpivoaka alina sy mivelona amin'ny karazan‐tsakafo maro; ary izany dia mety hitondra vokatsoa ho an'ny fihavoazan'ny ala sy ny fiazonana ny fahamaroan'ny kazan‐java‐maniry. Farnay, manavao ny fahalalana momba ny fiatraikan'ny fitondran‐tena sy fisakafoan'ireo karazam‐biby ireo ity fikarohana ity, izay afaka ampiasaina ho amin'ny fiarovana azy ireo sy ny fikajiana ny tontolo misy azy eto Madagasikara. … (more)
