Even though Arctic species richness is increasing via immigration from the South, many Arctic vertebrates are expected to become increasingly threatened during this century, and adjustment via phenotypic plasticity is likely to dominate vertebrate responses in the short term.
The effects of parasite age and intensity on variability in acanthocephalan-induced behavioural manipulation.
Differential influence of Pomphorhynchus laevis (Acanthocephala) on the behaviour of native and invader gammarid species.
No genetic bottleneck or associated microparasite loss in invasive populations of a freshwater amphipod
The data suggest that D. villosus invasion was either massive, or recurrent, or both, allowing a parasitic cortege to follow the host, and the maintenance of genetic diversity may have contributed to its success, including the variation in resistance in the face of the natural enemies.
Patterns of Biological Invasions in French Freshwater Systems by Non-Indigenous Macroinvertebrates
The present work gives a list of the 43 French freshwater non-indigenous species, which represent 1.2% of the French freshwater macroinvertebrates, and provides their geographic origins, their distributions among zoological units by comparison with the native fauna and their functional characteristics according to a recent typology based on bio/ecological traits.

An approach that compares the functional responses (FRs) of invader and native amphipod crustaceans is explored, proposing that if FRs of other taxa and trophic groups follow such general patterns, this methodology has potential in predicting future invasive species impacts.
Modification of hosts' behavior by a parasite: field evidence for adaptive manipulation.
The results indicate that the modifications induced by P. laevis are specific to the definitive host and do not increase the risk of predation by inappropriate hosts, here the adult edible frog Rana esculenta.
Confrontation of cryptic diversity and mate discrimination within Gammarus pulex and Gammarus fossarum species complexes
DNA barcoding is used to assess genetic diversity within and among amphipod populations and examined mate discrimination and pre-copulatory pair formation between genetically divergent individuals, suggesting cryptic diversity is common in the G. fossarum/G.pulex groups and that pre-zygotic isolation through mate discrimination, rather than post-zyGotic incompatibility, is likely to drive cryptic speciation.
Rapid range extension of the Ponto-Caspian amphipod Dikerogammarus villosus in France: potential consequences
A comparison of the amphipod fauna between 2003 and ancient surveys shows that some native species tend to disappear in the East of France, which suggests an ongoing homo- genisation process of amphipOD assemblages.
Energetically costly precopulatory mate guarding in the amphipod Gammarus pulex: causes and consequences
The results show for the first time an energetic cost of PCMG in male G. pulex, and indicate that such a cost is more likely to result from pair formation than from the cost of carrying the female, as has previously been assumed.
