Life history of a native emydid turtle (Malaclemys terrapin centrata) on the remote oceanic islands of Bermuda
… (Malaclemys terrapin) are native to the remote oceanic islands of Bermuda and presently inhabit only four small brackish water ponds on a private golf course. The life history of this species is poorly understood on Bermuda and so the aim of this study was to fill these knowledge gaps, to …

Population Genomic And Phenotypic Diversification In African Reed Frogs
… on how global climate shifts and isolation on oceanic islands drive evolutionary processes and patterns of community assembly and how organismal differences in habitat use and breeding biology influence species responses to these shared global events. Reed frogs (Hyperoliidae) are an ideal …

Octocorallia (Cnidaria: Anthozoa) da plataforma continental e ilhas oceânicas brasileiras: famílias Paramuriceidae e Plexauridae
… from the Brazilian continental platform and oceanic islands, from depths between 20 and 400m, were studied regarding aspects of their taxonomy, bathymetry, and geographical distribution. These species included nine Paramuriceidae (Bebryce cinerea, Bebryce sp., Heterogorgia uatumani, …

Microanatomia e sistemática das espécies de Zoanthus Lamarck, 1801 (Cnidaria, Anthozoa, Zoanthidea) do litoral e ilhas oceânicas do Brasil
… Lamarck, 1801, that occur on the coast and oceanic islands of Brazil are surveyed and redescribed. Four species are involved: Zoanthus sociatus (Ellis, 1767) is widely distributed from Ceará to São Paulo and also occur on Atol das Rocas, Fernando de Noronha Island and Abrolhos Reefs; …

The effects of introduced mice on seabirds breeding at sub-Antarctic Islands
… at risk of extinction. Introduced predators at oceanic islands where many seabirds breed account for the largest proportion of population declines, more so than incidental fisheries bycatch or degradation of their breeding habitats. Since few oceanic islands have escaped invasion, the problem is …

Relations between forest and prairie fragmentation and depredation of artificial nests in Missouri
… this model was originally conceptualized for oceanic islands, it recently has been applied to terrestrial habitat islands to explain effects of fragmentation. Direct relationships between avian species number and habitat area have been documented for many habitat types (e.g., marshes (Brown …

Parvulastra exigua in South Africa: one species or more?
… of Africa, southeastern Australia and several oceanic islands. In South Africa, it is found in sympatry with the endemic Parvulastra dyscrita and the two are differentiated predominantly by gonopore placement. P. exigua gives rise to distinct lecithotrophic benthic larvae that hatch from sticky …

The intertidal and shallow subtidal food web of sub-antarctic Marion Island
… subsequently declared a nature reserve. Isolated oceanic islands have always presented interesting opportunities for biological research on both the marine mammals and birds which use them for breeding purposes and the resident, often specially adapted, fauna and flora which colonise them. The …

The spatial scale of immune gene variation within and among bottlenecked populations
… bottlenecked passerine endemic to the oceanic islands of the Canary, Selvagens and Madeira archipelagos. I first investigated the evolution of key innate immune genes among the populations that the pipits inhabit. I found that while demographic history has played the major role in …

Investigating groundwater derived nutrient fluxes within Tauranga harbour, New Zealand
… permeable sediments and high rainfall, oceanic islands, may have the potential for disproportionally large SGD fluxes into the ocean compared to river inputs. Since SGD is driven under different timescales and processes (saline porewater through sediments and fresh groundwater from …

Phylogenetic Systematics and Evolution within the Family Scincidae
… questions ranging from the colonization of oceanic islands, to the evolution of limb loss, yet most of these and other questions remain understudied. The purpose of this dissertation is to use multiple mitochonidrial and nuclear DNA markers in connection with current cladistic methods to …

Global isotopic signatures of oceanic island basalts
… isotopic analyses of 477 samples representing 30 islands or island groups, 3 seamounts or seamount chains, 2 oceanic ridges and 1 oceanic plateau [for a total of 36 geographic features] are compiled to form a comprehensive oceanic island basalt [OIB] data set. These samples are supplemented by 90 …
