symmetry are formed. This is a high order commensurate phase with 30 atoms in the unit cell. From the measurement of the island diffraction peak profiles we find a power law for the mean island size versus coverage with an exponent n = 0.54 ± 0.03. A scaling behavior of growth is confirmed and a simple model describing island growth is presented. Due to the high degeneracy of the monolayer phas...

Recent sea surface height (SSH) trends in the South Pacific are substantially greater than North Pacific. Here, we use Estimating Climate and Circulation of Ocean Version 4 Release ocean state estimate Reanalysis System 5 to identify forcing mechanisms underlying that meridional asymmetry during 2005–2015. Thermosteric contributions dominate spatial structure SSH trends, but from local heat flu...

Ravinement surfaces are produced when the sea floor is eroded into a flat surface by the action of waves or tides during a marine transgression. They are preserved in the transgressive deposits as a sharp erosion surface. In a geological cross section across the ancient shoreline, primary ravinement surfaces appear as a subhorizontal line slightly dipping toward the sea. In a cross section, com...

Few of the Pelecaniformes are globally threatened, although some island and inland populations of pelecaniform birds have become extinct in the face of habitat loss and contamination. In some species (e.g., double-crested cormorant, white pelican), numbers are increasing with near-exponential growth, while in others (e.g., Dalmatian pelican) population abundance is rapidly decreasing. Island sp...

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...

We present the most comprehensive genetic characterization to date of five Fijian island populations: Viti Levu, Vanua Levu, Kadavu, the Lau Islands, and Rotuma, including nonrecombinant Y (NRY) chromosome and mitochondrial DNA (mtDNA) haplotypes and haplogroups. As a whole, Fijians are genetically intermediate between Melanesians and Polynesians, but the individual Fijian island populations ex...

[1] Two cases of upstream propagation of atmospheric solitons generated by atmospheric flow over topography were identified on two RADARSAT-1 synthetic aperture radar (SAR) images acquired near St. Lawrence Island in the Bering Sea on 7 September 1997 and 6 June 2001, respectively. In both cases, a group of solitons was shown as three darkbright linear features on the SAR images. The soliton wi...

The Nicobar Shrew Crocidura nicobarica (Miller, 1902) is an endemic and ‘Critically Endangered’ species restricted to Great Island in the Andaman Sea, India. Predation instance on by a Cattle Egret reported herewith for first time littoral forests near Govind Nagar, Island.
