Article
Both marine environment and biota are affected by microplastics, thus requiring a punctual and continuous monitoring of their presence and impacts. The number of studies analysing microplastics in vertebrate and invertebrates is continuously growing, but few generalizable patterns have been evidenced to date. This work explores some emerging hypoth...
Article
Full-text available
Relying on a purely taxonomic view of diversity may ignore the fact that ecological communities can be constituted of species having both distinct evolutionary histories and functional characteristics. Thus, considering how the multiple facets of diversity vary along environmental and geographic gradients may provide insights into the role of histo...

Full-text available
In this paper we used a beta diversity partitioning framework to test for the role of historic processes and current environmental changes in determining how the divergence and/or convergence of lineages and functions might have influenced the metacommunity structure of Mediterranean seagrass amphipods. Differently from other studies approaching be...
Article
Aim Hybrid populations can have intermediate, conserved or transgressive niches, compared to the parental species. Fine‐scale analyses can improve our understanding of niche evolution, but information on microhabitat differences between parental species and hybrids is extremely scarce for animal populations. We assessed the pattern and role of nich...

Habitat choice is defined as a nonrandom distribution of genotypes in different microhabitats. Therefore, it could exert a great impact on the genetic variance of natural populations by promoting genetic divergence, local adaptation, and may even lead to sympatric speciation. Despite this potential role in micro- and macro-evolutionary processes, t...
Article
Temporal variability in species composition and abundance may enhance coexistence in ecological communities, especially when subjected to strong seasonal patterns. Species distribution through time may be related to many factors, such as changes in the structure and functioning of preferred habitats, variations in ecological interactions or asynchr...
Article
Environmental stress can promote evolutionary forces and genetic divergence, but at which microgeographic scale divergence may arise, even in the presence of gene flow, remains poorly known. We studied the effects of eutrophication in a saltwork over a period of 6 years on the gene pool of a local population of the Mediterranean killifish Aphanius...
Conference Paper
Full-text available
Subtroglophiles organisms, able to exploit both caves and epigean habitats, offer an interesting perspective to understand how species responded to past climatic changes, since caves may act as local refugia to escape adverse climatic conditions. European cave salamanders of the genus Hydromantes are good candidates for these studies, since their t...
Article
The vagile fauna associated with Posidonia oceanica meadows is well studied due to the paramount importance of this Mediterranean habitat, but amphipod assemblages show a paucity of information despite the fact they form a relevant component of seagrass systems and associated food webs. This study analyzed the variability of amphipod assemblages in...
Article
Full-text available
The study of the European plethodontid salamander Hydromantes strinatii using allozyme and mitochondrial markers showed a strong geographical genetic structure. This was likely the outcome of different evolutionary mechanisms leaving their signature despite the effects of the genetic drift due to the low population size typical of this species. Two...

SUMMARY The unique environment of the Mediterranean Sea makes fish stock assessment a major challenge. Stock identification of Mediterranean fisheries has been based mostly from data on biology, morphometrics, artificial tags, otolith shape and fish genetics, with less effort on the use of parasites as biomarkers. Here we use some case studies comp...

Larvae of the genus Pseudoterranova constitute a risk for human health when ingested through raw or undercooked fish. They can provoke pseudoterranovosis in humans, a fish-borne zoonotic disease whose pathogenicity varies with the species involved, making their correct specific identification a necessary step in the knowledge of this zoonosis. Larv...

We validated the alkaline comet assay in two species of land snail (Helix aspersa and Helix vermiculata) to test their suitability as sentinels for primary DNA damage in polluted environments. The study was conducted under the framework of a biomonitoring program for a power station in Central Italy that had recently been converted from oil to coal...
Conference Paper
Macroinvertebrates are commonly used as environmental indicators in monitoring programs. Among crustaceans, amphipod communities play a relevant role in describing changes of sea bottom features, being therefore well appreciated as indicators. In this study the effects of sediment management off the Tyrrhenian coasts of Latium (Central Italy) have...
