This study reports the vertical distribution of fish larvae during the 1999 summer upwelling season in the Canaries-African Coastal Transition Zone (the CanariesACTZ). The transition between the African coastal upwelling and the typical subtropical offshore conditions is a region of intense mesoscale activity that supports a larval fish population dominated by African neritic species. During th...

Animal populations are frequently limited by the availability of food or of habitat. In central-place foragers, the cost of accessing these resources is distance-dependent rather than uniform in space. However, in seabirds, a widely studied exemplar of this paradigm, empirical population models have hitherto ignored this cost. In part, this is because non-independence among colonies makes it di...

The polyphase structural evolution of a sector the internal Central Apennines, where significance pelagic deposits atop neritic carbonate platform and active margin sediments has been long debated, is here documented. results new geological survey in Volsci Range, supported by stratigraphic constraints from syn-orogenic deposits, are integrated with analysis 2D seismic reflection lines availabl...

Hybridization is a fundamental evolutionary and ecological process with significant conservation ramifications. Sea turtle hybridization occurs at unusually high frequencies along the northeastern coast of Brazil. To better understand process, we studied reproductive output, migration patterns (through satellite telemetry), isotopic niches loggerhead turtles Caretta caretta olive ridley Lepidoc...

Abstract Kawakawa Euthynnus affinis is a cosmopolitan epipelagic tuna and regarded as one of the most commercially important tunas in subtropical tropical waters Indo-Pacific region. Regrettably, lack information on stock structure management conservation E. populations Malaysian could result overfishing perhaps decreasing this marine fish. Thus, for an effective successful species, assessment ...

Istrian Flysch was deposited during the Eocene in Dinaric foredeep and is composed of hemipelagic marls various gravity flow deposits. The latter are predominantly 5-40 cm thick turbidites, developed mostly as laminated cross-rippled sandstone beds (Tb-e, Tc-e Td-e Bouma sequences). In addition to there deposits characterized by a significant thickness, occasionally more than 10 m, described co...

To understand the spatio-temporal dynamics of juvenile chum salmon Oncorhynchus keta and their zooplankton prey, neritic Pseudocalanus newmani, oceanic Eucalanus bungii, Themisto japonica, we developed species-specific environmental DNA (eDNA) quantification methods. First, confirmed that collected in Otsuchi Bay preyed on target by stomach contents analyses using assays. Size-fraction water ba...

Forty two Paleocene benthic foraminiferal species of the Midway Formation in the Gulf Coastal Plain of Texas, USA were firstly investigated by Plummer (1927), and its paleogeographic distribution in some other countries in the Tethyan province were recorded: North America (USA, Mexico), South America (Argentina), Europe (North Sea Basin, Spain, France, Italy, Czech Republic, Bulgaria), North Af...

Heavy metals cadmium, lead, copper and zinc in neuston were analyzed from samples collected with a modified neuston net (310 μm mesh size) during an oceanographic cruise from July 29 to August 8, 2000 in the Straits of Malacca. The period of sampling coincided with South-West (SW) monsoon. The heavy metal concentrations in neuston were relatively low: ranging from 1.19-1013.70 μg g-1 wet weight...
