Seasonal and inter-annual variability of the phytoplankton communities in an upwelling area of the Alborán Sea (SW Mediterranean Sea)

open access: yesScientia Marina, 2005
Temporal variability (seasonal and inter-annual) in the assembly of phytoplankton communities from the northern Alborán Sea was investigated. For this purpose, the taxonomic composition of the micro- and nano-phytoplankton communities at three fixed ...

Contribution of larval growth rate vairability to the recruitment of the Bay of Málaga anchovy (SW Mediterranean) during 2000-2001 spawning seasons

open access: yesScientia Marina, 2003
Daily growth rates were estimated from larval anchovy (Engraulis encrasicolus) sampled in their main nursery grounds off the Bay of Málaga (SW Mediterranean) during the 2000 and 2001 spawning seasons.

Isotopic discrimination factors and nitrogen turnover rates in reared Atlantic bluefin tuna larvae (Thunnus thynnus): effects of maternal transmission

open access: yesScientia Marina, 2016
The use of stable isotope analysis to study animal diets requires estimates of isotopic turnover rates (half time, t50) and discrimination factors (Δ) for an accurate interpretation of trophic patterns.

Hidden demographic impacts of fishing and environmental drivers of fecundity in a sea turtle population

open access: yesConservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract Fisheries bycatch is a critical threat to sea turtle populations worldwide, particularly because turtles are vulnerable to multiple gear types. The Canary Current is an intensely fished region, yet there has been no demographic assessment integrating bycatch and population management information of the globally significant Cabo Verde ...

Postflexion larvae and juvenile daily growth patterns of the Alborán Sea sardine (Sardina pilchardus Walb.): influence of wind

open access: yesScientia Marina, 2006
The Alborán Sea is a hydrographically complex and variable area in which wind-driven coastal upwelling occurs. Its most abundant small pelagic resource is the sardine (Sardina pilchardus), which is subject to major interannual oscillations.

Genetic connectivity between Atlantic bluefin tuna larvae spawned in the Gulf of Mexico and in the Mediterranean Sea [PDF]

open access: yesPeerJ, 2021
The highly migratory Atlantic bluefin tuna (ABFT) is currently managed as two distinct stocks, in accordance with natal homing behavior and population structuring despite the absence of barriers to gene flow.

Long-Term Changes in the Water Mass Properties in the Balearic Channels Over the Period 1996–2019

open access: yesFrontiers in Marine Science, 2021
The analysis of a 24-year time series of Conductivity-Temperature-Depth (CTD) casts collected in the Balearic Channels (1996–2019) has allowed detecting and quantifying long-term changes in water mass properties in the Western Mediterranean.

Isotopic composition of particulate organic nitrogen and its relationship to nitrate assimilation in the Mediterranean Sea

open access: yesScientia Marina, 2010
The shifts in the 15N:14N ratio of particulate organic nitrogen (PON) suspended in the upper layer of the ocean have normally been interpreted in terms of changes in the isotopic composition of the source nitrogen used by the phytoplankton (nitrate ...
