House mice from 24 Scottish and Faroese islands show positive correlation of skeletal size with island area, conforming to a model of resource limitation in very small islands. Molar size is not correlated with island size, suggesting greater genetic canalization; smaller individuals have larger tooth to body size ratio. The size variation may have a simple genetic basis or may be ecophenotypic...

Excitons in a quantum well depend on the interfacial roughness resulting from its growth. The interface is characterized by islands of size j separated by one monolayer steps across which the confining potential decreases by V0 for wider wells. A natural length is the localization length j05p\/A2MV0 characterizing the minimum size island to confine an exciton. For small islands (j,j0), the abso...

Island systems generally have fewer species than continental areas due to their small size and geographical isolation. Low island diversity reduces the possibility of exportation of island lineages and island systems are not thought to have a major influence on the build-up of continental diversity. However, the view that islands represent the end of the colonization road has recently been chal...

The effects of mobility of small islands on island growth in molecular beam epitaxy are studied. It is shown that small island mobility affects both the scaling and morphology of islands during growth. Three microscopic models are considered, in which the critical island sizes are i∗ = 1, 2 and 3 (such that islands of size s ≤ i∗ are mobile while islands of size s ≥ i∗ +1 are immobile). As i∗ i...

Observations were made of birds and mammals on Adams Island and the southern end of the main Auckland Island between 2 November and 7 December 1989. Thirty-five bird species, fur seals and sealions were observed. Five Auckland Island rail were captured and many more heard on Adams Island. Counts of wandering and royal albatross, yellow-eyed penguins, Auckland Island teal and Auckland Island dot...

The ixodid tick Ixodes granulosus Supino 1897 was found infesting Rattus rattus in Semakau island, one of the small offshore islands fringing Singapore to the south. None of the examined R. rattus from the other islands fringing Singapore, or from Singapore island were found infested. Ixodes granulatus occurs, however, on Singapore island on Rattus annandalei, resident of undisturbed forested h...

Genetic studies of rare and endangered species often focus on defining and preserving genetically distinct populations, especially those having unique adaptations [1, 2]. Much less attention is directed at understanding the landscape of deleterious variation, an insidious consequence of geographic isolation and the inefficiency of natural selection to eliminate harmful variants in small populat...

The importance of language in the changing usage of particular environments is a topic worthy of greater attention than hitherto. Fraser Island has passed through a period of intense political conflict to one in which it is dominated by the new discourse of ecotourism. It is now part of that global development in which it is claimed that tourists can become properly informed about, and become p...

Estimates of speciation times are subject to a number of potential errors. One source of bias is that effective population size (Ne) has been shown to influence substitution rates. This issue is of particular interest for phylogeographic studies because population sizes can vary dramatically among genetically structured populations across species' ranges. In this study, we used multilocus data ...

An emerging paradigm for the dissipation of magnetic turbulence in the supersonic solar wind is via localized quasi2D small-scale magnetic island reconnection processes. An advection-diffusion transport equation for a nearly isotropic particle distribution describes particle transport and energization in a region of interacting magnetic islands [1; 2]. The dominant charged particle energization...
