Summary: The research investigated the production of a fermented crab condiment as a control method for an invasive species. Results showed that most biochemical changes occurred early in the fermentation process, indicating a need for further understanding and acceleration of the later stages.

Summary: The study analyzed the effects of climate variability on the population dynamics of the green crab Carcinus maenas in the Mondego estuary from 2003 to 2018. It found that recruitment of C. maenas increased during drought periods, with ontogenic stage segregation observed and a correlation between biological features of C. maenas and environmental variables identified through cumulative sums analysis. This highlights the importance of long-term datasets in understanding the impacts of extreme weather events on estuarine species.

Summary: The study revealed that the European green crab in Golfo Nuevo has a broad omnivorous diet, with a major contribution from the phytoplankton chain rather than direct consumption of algae. By combining three complementary techniques, differences in the diet between male and female crabs were detected, suggesting that they are not as ecologically equivalent as previously thought. Additionally, sequences corresponding to C. aestuarii were found, indicating that the Patagonian green crab population may be a hybrid of both sister species.

Summary: The study demonstrates that the population of Atlantic rock crabs in Icelandic waters is increasing, making it the dominant brachyuran crab species on soft substrate bottoms in the region, competing with native species such as the European green crab and spider crab. While the size of rock crabs remains relatively stable, there is a significant reduction in size observed in male spider crabs.

Summary: The study found that European green crabs shed low levels of DNA throughout most of their life cycle, emphasizing the importance of considering life stage and sampling methodology when using eDNA to monitor crustaceans in estuarine environments.

Summary: The early detection of invasive species is crucial to protect the environment, and environmental DNA analysis is a promising non-harmful method. Few studies have explored the use of eDNA for arthropods, as their exoskeleton may limit the release of eDNA. This study demonstrates that eDNA analysis can be used for crustaceans with an exoskeleton and emphasizes the importance of testing primers and probe sequences on local fauna at each location.

Summary: Most marine invertebrates disperse during a planktonic larval stage, but face the challenge of returning to coastal nursery habitats. Study on shore crab larvae shows that their successful coastal settlement is influenced by tidal rhythmicity and circadian rhythmicity. Genetic population structure is largely driven by differential allele frequencies between micro-, meso- and macrotidal areas, with strong allelic clines. Differential gene expression of clock genes further highlights phenotypic differences among genetic clusters, potentially linked to larval behavior.

Summary: Research on metallothionein in shore crabs showed that the concentrations and inducibility of MT are related to heavy metal concentrations such as cadmium, and vary with crab size but not age.

Summary: This study compares the range expansion of the European green crab and the lined-shore crab following El Nino events, and finds that the shorter larval duration and presence of larval incubators contribute to the successful establishment of European green crab populations in new areas.

Summary: This study examined the impact of barnacle epibionts on the condition of shore crabs in the western Wadden Sea. The results showed that fouling by barnacles significantly affected the energetic condition of the crabs, resulting in a reduced energy density. This reduction was especially pronounced in females and green forms of crabs.

Summary: This study uses interviews and long-term data analysis to characterize the evolution and impacts of the Atlantic blue crab invasion in the western Mediterranean. The research finds that the blue crab dominance in aquatic communities has led to significant declines in several species, hindering their recovery even at low abundances.

Summary: Research on European shore crabs reveals that females use UDP and UTP nucleotides as sex pheromones, with UDP acting as a mating signal and UTP as an attractant. Mixing these nucleotides in a specific ratio enhances mating responses, showcasing the importance of pheromone bouquets in maximizing reproductive success and species-specificity.

Summary: This study investigated the effects of boat noise and shore crabs' predator cues on mussel behavior. Mussels responded to boat noise and free-ranging predators by reducing their valve opening. Valve opening serves as an indicator of food intake, and the impacts of predators and noise provide insights into mussel fitness consequences. Despite the important role of invertebrates, such as bivalves, in the marine ecosystem, they have received limited attention compared to marine mammals and fishes affected by human activities.

Summary: The laboratory experiments conducted in 2016 revealed that Asian shore crabs exhibit cannibalism, with factors such as prey size and the presence of food affecting cannibalism rates. Adult and large juvenile crabs consumed megalopae and small juveniles, with megalopae being heavily preyed upon. This cannibalism could potentially impact recruitment to benthic populations of this non-native crab species.
