Island Biogeography and Restoration: The Role of Living Fence Islands as Regeneration Foci in the Rehabilitation of Degraded Lands in Honduras
… of 543 seedlings of 41 species established in islands. Seedling number did not differ among island types, although a trend toward greater density was apparent in artificial islands. Species richness was greater in Gliricidia islands than in Bursera or open pasture islands. Seedlings were also …

The Effect of Spatial and Environmental Drivers on Patterns in Species Richness and Composition
… patterns and their underlying drivers. Islands and isolated systems are in the focus of this work. Islands provide optimal conditions to study biogeographic patterns. Theoretical advances in ecology have been initiated by island biogeography. Theory on island biogeography has …

The Effect Of Spatial Subsidies On The Diet, Density, And Species Richness Of Insular Lizards In The Gulf Of California
I used lizards on islands in the Gulf of California to evaluate the effects of materials moving from onto islands. Materials are transported onto the islands by both tidal action and seabirds. I used the stable isotopes of carbon (¹³C/¹²C) and nitrogen (¹⁵N/¹⁴N) to analyze the diets of Uta …

Relations between forest and prairie fragmentation and depredation of artificial nests in Missouri
… the remaining areas. Principles derived from island biogeography offer possibilities for conserving species in fragmented habitats. MacArthur and Wilson (1967) proposed that the number of species on an island is a balance between immigration and extinction rates; this equilibrium point may be …

Patterns of microbial community development in isolated aquatic systems
… to the MacArthur-Wilson equilibrium theory of island biogeography and suggest alternative models for the observed patterns. Water-filled plastic containers were used as aquatic islands to investigate the colonization dynamics of protozoan, algal and microinvertebrate taxa. Polyurethane foam …

Seasonal patterns of colonization by protozoa in an oligotrophic lake
… lake's pelagic water to simulate barren habitat islands suitable for colonization by protozoa. The results were interpreted with respect to the MacArthur-Wilson equilibrium theory of island biogeography. Results showed seasonal changes can cause a substantial amount of instability in colonization …

How Historic Shipwrecks Influence Dispersal of Deep-Sea Microbiomes
… theories in ecology, specifically the Theory of Island Biogeography and the Wooden Stepping Stone hypothesis. These have not been investigated for microorganisms, and thus this work will probe if they are applicable to microbial biogeography in this habitat. Experiments were conducted to …

Survey of the Native and Nonnative Vascular Plant Species of Three Islands in Lake Winnipesaukee, New Hampshire
… patterns in vascular plant composition on three islands in Lake Winnipesaukee, NH. It also tested the role of island biogeography in ecology as it analyzed the effectiveness of a land use plan implemented on the islands. Samplings were made on the islands in the summer of 2011 and were compared …

Species richness and metacommunity dynamics in bryophytes
… surface area, confirming the area predictions of island biogeography theory. From the four metacommunity perspectives (Leibold et al., 2004), only the neutral paradigm was not observed. This suggested that an amalgamation of metacommunity paradigms govern bryophyte species composition on local …

Botanical processes in urban derelict spaces
… application of principles of metapopulation and island biogeography principles to urban conservation. In particular the trend for planners to designate urban wildlife corridors is questioned as being probably of no benefit to native diversity and indeed these features are identified as being …

Biogeography and conservation of terrestrial afrotropical birds
… Differences can probably be attributed to island biogeography and aerography theory.

Biogeography of Montane Mammals on the Colorado Plateau and Adjacent Regions
… central clade, a northwest clade, and an Alaskan island clade. Evidence also supports differentiation of a 'southern Rockies' clade and a distinct 'southwest island' clade. Populations of M. longicaudus north and west of the Colorado River (Boulder and Henry Mts.) share two haplotypes, form a …

Species Distribution and Richness Patterns of Bird Communities in the High Elevation Forests of Virginia
Island biogeography theory predicts that the patterns and distributions of spatially isolated populations are governed by large scale processes. The high elevations forests in the Southern Appalachians represent a series of naturally fragmented islands that harbor many isolated populations of …

'Islands' in an island: multiscale effects of forest fragmentation on lowland forest birds in Taiwan
… birds in Taiwan. At a regional scale, Island Biogeography Theory was applied to examine area and isolation effects on species richness of lowland-forest birds using bird data derived from Breeding Bird Survey Taiwan in 2009 and 2010. I also investigate the differential responses of two …

Fish Community Assembly in the Missouri River Basin
… drainages of the Missouri River. I took an island biogeography approach and tested to determine whether tributaries were insular in the sense that tributary drainage area and isolation from the source of colonists could account for native species richness and composition. I focused on …

Parasite communities of wild turkeys (Meleagris gallopavo) in Colorado
… and specifically the helminth parasites. Island Biogeography Theory has been applied to parasite and host relationships in which the host is considered an island. In particular, the Island Size hypothesis predicts that a larger island will allow for greater species diversity due to the …

The Implications of the Target-Area Hypothesis on the Population Dynamics of the Spotted Spiny Lobster, <i>Panulirus guttatus</i>
… target-area hypothesis, based on the theory of island biogeography, predicts that larger islands are more effective at intercepting passive immigrants. Most marine invertebrates have meroplanktonic larvae and open population dynamics, so immigration to populations in isolated benthic habitats is …

Assessment of bird diversity, feeding guild and avitourism potential in Pulau Tinggi Marine Park, Mersing, Johor, Malaysia.
Small islands are known for their fundamental role in providing vital pitstop for migratory birds. Moreover, island birds are important models for Island Biogeography Theory. However, research on birds on Malaysian islands are lacking whereas most research mainly concentrated on marine lives. Thus, …

Patterns and Disturbance-Induced Drivers of Plant Diversity and Endemism on High Elevation Islands
… and define the concept of high elevation islands (HEI), which – in my opinion – are ideal research objects to address ecological and biogeographic questions. I intend to bridge the gap between island biogeography (i.e. by focusing on the global scale) and island ecology (i.e. by addressing …
