Are island and mainland biotas different? Richness and level of generalism in p...
Santos, Ana M. C.; Fontaine, Colin; Quicke, Donald L. J.; Borges, Paulo A. V.; Hortal, JoaquínCopyright © 2011 Th e Authors. Oikos © 2011 Nordic Society Oikos. ; Island communities are exposed to several evolutionary and ecological processes that lead to changes in their diversity and structure compared to mainland biotas. These phenomena have been observed for various taxa but not for parasitoids, a key group in terms of community diversity and functioning. Here we use the parasitoid communities assoc...
Species pool structure determines the level of generalism of island parasitoid ...
Santos, Ana M. C.; Quicke, Donald L. J.; Borges, Paulo A. V.; Hortal, JoaquínCopyright © 2011 Blackwell Publishing Ltd. ; AIM To examine whether island parasitoid faunas are biased towards generalists when compared with the mainland and their species pool, and to evaluate the effects of climate, island characteristics and regional factors on the relative proportions of idiobionts (i.e. generalists) and koinobionts (i.e. specialists) of two parasitic wasp families, Braconidae and Ichneu...
Are species-area relationships from entire archipelagos congruent with those of...
Santos, Ana C.; Whittaker, Robert J.; Triantis, Kostas A.; Borges, Paulo A. V.; Jones, Owen R.; Quicke, Donald L. J.; Hortal, JoaquínCopyright © 2010 Blackwell Publishing Ltd. ; AIM To establish the extent to which archipelagos follow the same species–area relationship as their constituent islands and to explore the factors that may explain departures from the relationship. LOCATION Thirty-eight archipelagos distributed worldwide. METHODS We used ninety-seven published datasets to create island species–area relationships (ISARs) using the A...
