Application of pyrolysis-GC/MS for the characterisation of suspended particulate organic matter in the Mediterranean Sea: a comparison with the Black Sea

open access: yes, 2000
Suspended particulate organic matter (SPOM) both from the oligotrophic Mediterranean and from the more productive Black Sea has been analysed by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and by such conventional techniques as elemental ...

Composition and abundance of octocorals in the Sea of Marmara, where the Mediterranean meets the Black Sea

open access: yesScientia Marina, 2015
Species composition and abundance of octocoral assemblages were investigated in the Sea of Marmara, which forms the connection between the Mediterranean and the Black Seas, two semi-enclosed seas with peculiar oceanographic conditions. Fourteen octocoral

Social and population structure of striped and Risso's dolphins in the Mediterranean Sea [PDF]

open access: yes, 2004
The aim of this research was to apply genetic methods to a better understanding of the evolution of population genetic structure in two dolphin species inhabiting a shared geographic range in the Mediterranean Sea and eastern North Atlantic (ENA).

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Foraging dives of sperm whales in the north-western Mediterranean Sea

open access: yes, 2012
Oceanic odontocetes rely on echolocation to forage on pelagic or benthic prey, but their feeding ecology is difficult to study. We studied sperm whale foraging dives during summer in the north-western Mediterranean, using visual and passive acoustic ...

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

open access: yesThe Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

Environmental concerns in the Mediterranean sea: Pollution and climate change [PDF]

open access: yes, 2023
The ecosystem in the Mediterranean is in grave danger of deterioration. Marine species quickly decline as their habitats are damaged daily due to persistent tourism, plastic and chemical pollution, unsustainable fishing, and fast-growing coastal human ...

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Evaluation of the seahorse Hippocampus guttulatus home range size at Mar Piccolo of Taranto (Ionian Sea, Central Mediterranean Sea, Italy)

open access: yes, 2021
Knowledge of the biological cycles and interactions with the environment represents a fundamental requisite for drafting management protocols for threatened species and those with the fragmented distribution.

A Geomorphometric Approach to Estimate the Deterioration of Earthen Archaeological Sites by Rainfall and Diffusion Processes: The Huaca Chornancap (Eighth–14th Century ad), Lambayeque, Peru

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Rain‐induced erosion processes can severely damage Earthen archaeological sites. Huaca Chornancap (HCH; eighth–14th century ad) is a platform located in the Lambayeque region (Peru) exposed to seasonal rain due to El Niño Southern Oscillation (ENSO).
