The dramatic latitudinal cline in P-M hybrid dysgenesis characteristics along the east coast of Australia is not smooth. Tests of recent collections of Drosophila melanogaster from the southeastern coast define the previously described cline as comprising three discrete, apparently contiguous regions of P, Q and M phenotypes, respectively. Northern populations from Cairns (16.9 degrees SLat) to...

In this study, we analyze the influence of Great East Japan Earthquake, which occurred on 11 March 2011, shoreline northern Ibaraki Coast. After earthquake, area experienced subsidence approximately 0.4 m. Shoreline changes at eight sandy beaches along coast are estimated using various satellite images, including ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer), ALOS AVNIR...

Sterna hirundinacea (Lesson, 1831) is a migratory seabird that breeds in the Pacific Coast (from Peru to Chile) and along the Atlantic coast of South America from Espírito Santo (Brazil) to Terra del Fuego (Argentina). This paper describes the reproductive success of South American Terns on Cardos Island, Florianopolis, Brazil in the breeding seasons of 2003, 2005 and 2006. The colony was forme...

During the past ten years a rather large number of vertebrae and other portions of skeletons of cetaceans have been obtained from the Calvert Miocene formation of Maryland. Most of these specimens were obtained by digging into the Calvert Cliffs. During severe storms many tons of sandy clay are dislodged from the face of the cliff by the undercutting action of the incoming tide. Many specimens ...

BACKGROUND In situ air sparging (IAS) was undertaken at sites in the tidal flats of Mandol and Hajeon, on the west coast of South Korea, to estimate variations in the radius of influence (ROI). RESULTS The Mandol core sample consisted of sand and muddy sand 1.6-3.4 [Formula: see text] (average 2.3 [Formula: see text]) and contained water (average 15.10 %). The Hajeon core sample consisted of ...

In this contribution, we report the generation of 17-μJ mid-infrared (MIR) pulses with duration of 70 fs and bandwidth of 550 nm centered at 3.75 μm at 1-kHz repetition rate, by a two-stage femtosecond optical parametric amplifier utilizing 4H-silicon carbide crystal as the nonlinear medium. The crystal is selected as it processes orders of magnitude higher damage threshold than traditional MIR...

Forecasting hurricane impacts of extremewinds and flooding requires accurate prediction of hurricane structure and storm-induced ocean surface waves days in advance. The waves are complex, especially near landfall when the hurricane winds and water depth varies significantly and the surface waves refract, shoal and dissipate. In this study, we examine the spatial structure, magnitude, and direc...

Abstract Underwater visual census (UVC) is a commonly used approach for assessing fish density and biomass. Iskenderun Bay, comprising the Samanda? coast in Turkey, most important introduction pathway of alien species northeastern Mediterranean. In this study, density, abundance, distribution interaction invasive lionfish or devil firefish Pterois miles were assessed using UVC method on coast. ...
