Benthic megafauna and the functioning of macroalgal forests and urchin barrens

open access: yesOikos, EarlyView.
Two temperate rocky reef food‐web models, representing the trophic diversity of the Mediterranean rocky reef communities, were built for the two stable states: macroalgal forests and barren grounds, which are characterized by opposite amounts of erect macroalgal biomass.

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Taxonomic diversity dynamics of early cretaceous brachiopods and gastropods in the Azerbaijanian domains of the Lesser Caucasus (Neo-Tethys Ocean) [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2014
Palaeontological data available from the Azerbaijanian domains (Somkhit-Agdam, Sevan-Karabakh, and Miskhan-Kafan tectonic zones) of the Lesser Caucasus permit reconstruction of the regional taxonomic diversity dynamics of two groups of Early ...

Evaluation of active ingredients and nematodes against slugs and snails on organic lettuce [PDF]

open access: yes, 2008
Three years trials were carried out to evaluate the efficacy of some molluscicides for the control of slugs (Arion sp.) and snails (Cepaea nemoralis and Helix aspersa) on organic lettuce in Emilia-Romagna (Italy).

Micronuclei and Other Nuclear Abnormalities in Patella Limpet as Biomarkers of Cytogenotoxicity in Recreational Port Waters

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

A highly diverse molluscan assemblage associated with eelgrass beds (Zostera marina L.) in the Alboran Sea: Micro-habitat preference, feeding guilds and biogeographical distribution

open access: yesScientia Marina, 2009
The fauna of molluscs associated with deep subtidal Zostera marina beds (12-16 m) in southern Spain (Alboran Sea) has been characterised in terms of micro-habitat preference, feeding guilds and biogeographical affinity.

Artificial supplementary food influences hedgehog occupancy and activity patterns more than predator presence or natural food availability

open access: yesWildlife Biology, EarlyView.
Supplementary feeding for declining hedgehog Erinaceus europaeus populations is popular in Great Britain and has been suggested as an important factor in explaining higher densities in urban areas compared with rural ones. Occupancy modelling was used to test whether spatial variation in supplementary feeding, natural food, habitat, or predator ...
