Abstract Indonesia, which consists of 16,671 named islands and 104,000 km coastline, is the biggest archipelagic state a host to precious essential coastal small island goods services.
Small rodents with multi-annual population cycles strongly influence the dynamics of food webs, and in particular predator-prey interactions, across most of the tundra biome. Rodents are however absent from some arctic islands, and studies on performance of arctic predators under such circumstances may be very instructive since rodent cycles have been predicted to collapse in a warming Arctic. ...
Primers were used to amplify a 561-bp region of the 16S rRNA gene of Ehrlichia phagocytophila from Ixodes scapularis ticks and small mammals collected in Rhode Island and Connecticut. DNA sequences for all 50 E. phagocytophila-positive samples collected from 1996 through 1998 in southwestern Connecticut were identical to the sequence reported for E. phagocytophila DNA from confirmed human cases...
Compared to the mainland, boreal oceanic islands would be expected to have a depauperate lichen biota because of their isolation, small area, exposure to salt spray and structurally simple habitats. We surveyed the macrolichens (non-crustose lichens) and quantified habitat associations on Kent Island, an 80-hectare island that lies at the mouth of the Bay of Fundy, New Brunswick, Canada. A tota...
Islands acquire species through immigration and speciation. Models of island biogeography should capture both processes; however quantitative island biogeography theory has either neglected speciation or treated it unrealistically. We introduce a model where the dominance of immigration on small and near islands gives way to an increasing role for speciation as island area and isolation increas...
Spatial variability in abundance and size of sponges are poorly understood compared with other sessile organisms such as corals. A hierarchical survey design across 3 spatial scales — sites nested in locations nested in island groups — examined variation in sponge size and abundance for the common coral reef sponge Coscinoderma matthewsi (Lendenfed, 1886) (Demospongiae: Dictyoceratida) in Torre...
