The Californian Channel Islands are near-shore islands with high levels of endemism, but extensive habitat loss has contributed to the decline or extinction of several endemic taxa. A key parameter for understanding patterns of endemism and demography in island populations is the magnitude of inter-island dispersal. This paper estimates the extent of migration and genetic differentiation in three extant and two extinct populations of Channel Island song sparrows (Melospiza melodia graminea). Inter-island differentiation was substantial (G''ST: 0.14-0.37), with San Miguel Island having the highest genetic divergence and lowest migration rates. Santa Rosa and Santa Cruz Island populations were less diverged with higher migration rates. Genetic signals of past population declines were detected in all of the extant populations. The Channel Island populations were significantly diverged from mainland populations of M. m. heermanni (G"ST: 0.30-0.64). Ten mtDNA haplotypes were recovered across the extant and extinct Channel Island population samples. Two of the ten haplotypes were shared between the Northern and Southern Channel Islands, with one of these haplotypes being detected on the Californian mainland. Our results suggest that there is little contemporary migration between islands, consistent with early explanations of avian biogeography in the Channel Islands, and that song sparrow populations on the northern Channel Islands are demographically independent. © 2015 Wilson et al.

Strain IK-1T was isolated from decaying tissues of the shrub Wikstroemia oahuensis collected on O'ahu, Hawai'i. Cells were rods that stained Gram-negative. Gliding motility was not observed. The strain was oxidase-negative and catalase-positive. Zeaxanthin was the major carotenoid. Flexirubin-type pigments were not detected. The most abundant fatty acids in whole cells of IK-1T grown on R2A were iso-C15:0 and one or both of C16:1ω7c and C16:1ωβc. Based on comparisons of the nucleotide sequence of the 16S rRNA gene, the closest neighbouring type strains were Flavobacterium rivuli WB 3.3-2T and Flavobacterium subsaxonicum WB 4.1-42T, with which IK-1T shares 93.84 and 93.67% identity, respectively. The G + C content of the genomic DNA was 44.2 mol%. On the basis of distance from its nearest phylogenetic neighbours and phenotypic differences, the species Flavobacterium akiainvivens sp. nov. is proposed to accommodate strain IK-1T (=ATCC BAA-2412T=CIP 110358T) as the type strain. The description of the genus Flavobacterium is emended to reflect the DNA G + C contents of Flavobacterium akiainvivens IK-1T and other species of the genus Flavobacterium described since the original description of the genus. © 2013 IUMS.

Ordnance Reef, located just off the west coast of the island of O'ahu, Hawaii, is a shallow-water site (~6-10 m water depth) where conventional munitions were disposed following World War II. Over the past decade, the site has been extensively mapped and sampled by the U.S. Army and National Oceanic and Atmospheric Administration (NOAA) using a wide variety of techniques. In the summer of 2011 at Ordnance Reef, we deployed an underwater time-lapse camera that was developed as part of a student science fair project to capture images of the interaction between the ocean environment and two munitions over an approximately 24-h period. During the deployment, the system photographed 10 species in the vicinity of munitions, three of which came into direct contact with munitions casings. Our project demonstrates that time-lapse photography could potentially be an inexpensive and effective approach for documenting the effects of munitions on the ocean environment and its residents.
