Strained islands formed in heteroepitaxy sometimes change shape during growth. Here we show that there is typically a first-order shape transition with island size, with the discontinuous introduction of steeper facets at the island edge. We present a phase diagram for island shape as a function of volume and surface energy, showing how surface energy controls the sequence of island shapes with...

Three new Brachinus species namely B. grootaerti n. sp. (Palawan Island), B. palawanensis n. sp. (Palawan Island), B. mindanaoensis n. sp. (Mindanao Island) from Philippines were described. In addition, a modified key to the known Brachinus Philippine species is provided.

Aim Although bats of the Caribbean have been studied extensively, previous work is largely restricted to zoogeography, phylogeography or the effects of island characteristics on species richness. Variation among islands in species composition that is related to geographical or environmental variation remains poorly understood for much of the Caribbean. Location Caribbean islands, including the ...

This paper describes the first visit to Jacquemart Island in the south of the subantarctic Campbell Island group. The island contrasts with the main island by the absence of introduced grazing mammals, rats (Rattus spp.) and feral cats (Felis catus), and in the dominance of palatable plant species. A survey of the main vegetation communities was made and bird species seen were recorded. Specime...

Twenty rotifers (three Bdelloidea and 17 Monogononta, including new of Encentrum and Notholca) , a platyhelminth, two nematodes, two tardigrades, one cnchytraeid worm, four c1adoccrans, two copcpods and three species of mites were recovered from five small pools on Heard Island. The results indicate that the Heard Island fauna is closer to that of Signy Island and Macquarie Island than to that ...

Human activities such as oil and gas production can enhance the natural level of naturally occurring radioactive materials (NORM) in by-product and waste streams. Iran has been among the top five oil producing countries since 2005. This high production rate emphasizes the importance of NORM management to ensure the safety of humans and wildlife. Petroleum storage and transport facilities are lo...

We determine the equilibrium morphology of a strained solid lm for the case where it wets the substrate (Stranski-Krastanow growth). Using a continuum elasticity model with isotropic surface energy and equal elastic constants in the lm and substrate, we calculate an asymptotic solution for the axisymmetric three-dimensional equilibrium shape of a small island, where the height is much less than...
