Multiple Source Pools And Dispersal Barriers For Galápagos Plant Species Distribution, J. Alan Yeakley, John F. Weishampel

We reexamined geographic factors explaining the number of plant species on islands in the Galápagos Archipelago. We hypothesized that plant species richness (S) was related to the number of source pools and that plant species dispersal preferentially followed direct, oceanic pathways. To test different dispersal pathways from multiple source pools, the total number of islands within a given dispersal radius (i) was posed as the sum of the number of line-of-sight islands (Ci) and of the number of islands without line-of sight connection (Bi). In partial regression analyses, controlling for nearest island area (A2) …
Conservation Des Habitats De Roussettes De Livingstone – Les Massifs Forestiers D’Anjouan Et Moheli, Comores: Utilisation D’Indicateurs Sociaux Et Ecologiques, Elise F. Granek
Environmental Science and Management Faculty Publications and Presentations
Le déboisement sur les lles d'Anjouan et Moheli a augmenté a un taux alarmant au cours de ce siecle (PNUD 1998). Ce changement de la couverture des sols et des forets naturelles a des consequences nefastes pour toutes les especes vivant sur les iles, en particulier pour les especes vegetales et animales endemiques, et les communautes humaines locales. Pour diminuer la pression anthropique sur Ie milieu naturel, le Fonds pour l'Environnement Mondial et Ie PNUD ont mis en place un projet de cinq ans qui travaille avec Ie Ministere comorien de l'Environnement pour creer un reseau d'aires protegees dans les …
An Analysis Of Pteropus Livingstonii Roost Habitat: Indicators For Forest Conservation On Anjouan And Moheli, Elise F. Granek
An Analysis Of Pteropus Livingstonii Roost Habitat: Indicators For Forest Conservation On Anjouan And Moheli, Elise F. Granek

Livingstone's fruit bat (Pteropus livingstonii) is an endangered and endemic species found only on the islands of Anjouan and Mohéli, Comoros. A study was conducted into the habitats selected by P. livingstonii, as part of a project to assess areas for nature reserves which will be able to protect and conserve forest resources in the islands; the bat is postulated to be a useful indicator of undisturbed forest. Known roost sites (n=9) before the survey were between 500 and 1100 m altitude, on steeply sloping land, with some indigenous forest cover present. Thirteen new potential roost sites were identified, of …
