| positive indirect interactions between neighboring plant species via a lizard pollinator. | in natural communities, species are embedded in networks of direct and indirect interactions. most studies on indirect interactions have focused on how they affect predator-prey or competitive relationships. however, it is equally likely that indirect interactions play an important structuring role in mutualistic relationships in a natural community. we demonstrate experimentally that on a small spatial scale, dense thickets of endemic pandanus plants have a strong positive trait-mediated indire ... | 2007 | 17262697 |
| six new species of coccidia (apicomplexa: eimeriidae) from endangered phelsuma spp. geckoes (sauria: gekkonidae) of the black river gorges national park, mauritius. | six new species of coccidia are described from endangered phelsuma spp. geckoes (sauria: gekkonidae) endemic to mauritius, indian ocean. five new species (3 eimeria and 2 isospora species) are described from phelsuma rosagularis vinson et vinson; all lack a micropyle and an oocyst residuum, and all have a sporocyst residuum. oocysts of eimeria swinnertonae sp. n. are ellipsoidal, 22.2 x 17.8 (20.8-24.8 x 16.8-18.4) microm; si 1.25; polar granule absent. sporocysts are ellipsoidal, 8.8 x 7.0 (8.0 ... | 2009 | 20128235 |
| reconstructing an island radiation using ancient and recent dna: the extinct and living day geckos (phelsuma) of the mascarene islands. | mitochondrial (12srrna and cyt b, 1086 bp) and nuclear (c-mos, 374 bp) dna sequences were used to investigate relationships and biogeography of 24 living and extinct taxa of phelsuma geckos. monophyly of phelsuma and sister relationship to the sw african rhoptropella is corroborated. phelsuma originated on madagascar and made multiple long-distance invasions of oceanic islands including the mascarenes, aldabra, comores, seychelles, andamans, and perhaps pemba. the mascarenes were probably coloni ... | 2004 | 15019612 |
