The role of fisheries and the environment in driving the decline of elasmobranchs in the northern Adriatic Sea
Elasmobranch populations are declining worldwide, calling for urgent assessment of fishery exploitation and application of effective conservation strategies. Here, we applied a novel approach,…

New molecular tools for the identification of 2 endangered smooth-hound sharks, Mustelus mustelus and Mustelus punctulatus.
TLDR
A morphological identification of several Mustelus specimens was performed to select individuals unambiguously attributed to 1 of the 2 species, and 3 new molecular tests were developed and validated based on species-specific amplification of the cytochrome c oxidase subunit 1 (COI).

The highly rearranged mitochondrial genomes of the crabs Maja crispata and Maja squinado (Majidae) and gene order evolution in Brachyura
TLDR
This study confirms that the most widespread gene order (BraGO) represents the plesiomorphic condition for Brachyura and was established at the onset of this clade.

Multiple paternity and hybridization in two smooth-hound sharks
TLDR
The frequency of polyandrous litters in these species is consistent with aspects of their reproductive biology, such as synchronous ovulation and possible occurrence of breeding aggregations.

Food partitioning and diet temporal variation in two coexisting sparids, Pagellus erythrinus and Pagellus acarne.
TLDR
These sympatric congeneric fish species displayed clear food partitioning throughout the temporal scale analysed, linked to an increase in energy requirements for reproduction, together with the differing availability of preferred prey throughout the year.

Long-term changes in community composition and life-history traits in a highly exploited basin (northern Adriatic Sea): the role of environment and anthropogenic pressures.
The changes in a marine community in the northern Adriatic Sea were explored over a period of 65 years using landings data from a commercial fishing fleet, and the role of fishing pressure and…

From Trap to Nursery. Mitigating the Impact of an Artisanal Fishery on Cuttlefish Offspring
TLDR
The proposed mitigation measure reduced the impact of fishing on cuttlefish eggs, with no significant effect on the commercial catch.

The Clodia database: a long time series of fishery data from the Adriatic Sea
TLDR
A database of historical marine fishery landing data, covering a remarkably long time series (1945–2013) and referring to one of the most exploited areas of the Mediterranean Sea, the Adriatic Sea, is presented.

Reproductive resilience of ice-dependent Antarctic silverfish in a rapidly changing system along the Western Antarctic Peninsula
TLDR
Results were consistent with a single population at Charcot Island and Marguerite Bay and indicated substantial reproductive potential, which may mitigate population isolation and reductions in habitat availability but cannot ultimately offset catastrophic loss of spawning habitat linked to sea-ice retreat.

Life history strategies of the Scotia Sea icefish, Chaenocephalus aceratus, along the Southern Scotia Ridge
TLDR
Lower reproductive capacity around the SOI, and strong eastward flow in the large-scale circulation, suggests that the SSI may be more important in influencing distributions and abundance of icefish along the Southern Scotia Ridge.
