In the last 20 years several nonnative amphipod species have immigrated inland waters of Germany and adjacent central European countries. Some of them have been very successful and could establish stabile populations. In some places, they have even replaced native or earlier established species. The gammarid Echinogammarus berilloni originates from the Atlantic region of France and the north-western part of Spain and coexists in some central European waters with the native Gammarus pulex and G… 
Relative benefit of the invasive Echinogammarus berilloni (Catta, 1878) over native gammarids under fish predation (Gasterosteus aculeatus Linnaeus, 1758)
TLDR
The findings corroborate the assumption that the invader E. berilloni profits from sympatric occurrence with native gammarid species, especially when hideout options are available.
Mouthpart morphology of Synurella ambulans (F. Muller, 1846) (Amphipoda, Crangonyctidae)
TLDR
The morphology of the mouthparts and other structures involved in food acquisition of Synurella ambulans was studied using scanning electron microscopy and conclusions are drawn regarding the food spectrum of S. ambulans.
Morphology of the mouthparts and digestive system in two species of Uristidae Hurley, 1963 (Amphipoda: Lysianassoidea)
ABSTRACT In amphipods, the morphology of the mouthparts and digestive system is known to vary according to lifestyle and feeding habits. Since mouthparts are widely used in amphipod taxonomy and the
A eucrustacean from the Cambrian ‘Orsten’ of Sweden with epipods and a maxillary excretory opening
The Cambrian species Paulinecaris siveterae n. gen. n. sp., known from two trunk fragments, represents the first record of epipods (serving as gills and osmoregulatory structures) in a crustacean
Functional aspects of the gammaridean mandibles with special reference to the lacinia mobilis (Crustacea, Amphipoda)
TLDR
The entire action of right and left mandibles during the feeding act explains the asymmetrical morphology of the associate structures at the mandibular coxal ‘gnathal’ edges of gammarideans, possibly also of other malacostracans, at least those sharing a lacinia mobilis.
Effect of the environment on the interaction between gammarids (Crustacea : Amphipoda) and their manipulative acanthocephalan parasites
TLDR
A better understanding of the importance of the impact of parasites on their hosts is provided, allowing to make previsions on their subsequent ecological consequences.
Effectiveness of zebra mussels to act as shelters from fish predators differs between native and invasive amphipod prey
TLDR
D. villosus, whose affinity to dreissenids has already been established, utilizes them as protection from fish predators, including allopatric predators, more efficiently than other amphipods, Therefore, the presence of dreISSenids in areas invaded by D. villOSus is likely to help the invader establish itself in a new place.
The curse of being single: both male and female Gammarus pulex benefit energetically from precopulatory mate guarding
TLDR
The hypothesis that G. pulex females might benefit from being passively transported by their partner during PCMG, whereas the male alone bears the costs of swimming while carrying his mate is tested, and it is found that paired individuals contained more protein, lipid and glycogen reserves than single individuals in both sexes.
Interactions between large and small detritivores influence how biodiversity impacts litter decomposition
TLDR
This study demonstrates that interspecific differences in body size should be taken into account in diversity-decomposition studies, and uses a set of "diversity-interaction" models that explored how decomposition was affected by different interspecific interactions and the role of body size.
Consequences of Warming and Resource Quality on the Stoichiometry and Nutrient Cycling of a Stream Shredder
TLDR
The results show that the effects of reduced leaf quality on detritivore nutrient retention were more severe at higher temperatures because the shredders were not able to offset their increased metabolism with increased consumption or more efficient digestion when fed pool-conditioned leaves.

Mouthpart Morphology of Gammarus roeselii Compared to a Successful Invader, Dikerogammarus villosus (Amphipoda)
TLDR
Test the hypothesis that different modes of food acquisition are expressed in differences in the morphology of the mouthparts and other structures involved in feeding, such as the antennae and gnathopods, possibly are indicative of the success of D. villosus over G. roeselii.
Recent drastic changes in the gammarid fauna (Crustacea, Amphipoda) of the Vistula River deltaic system in Poland caused by alien invaders
During the last decade of 20th century, the nonindigenous gammarid species Gammarus tigrinus, Dikerogammarus haemobaphes, Pontogammarus robustoides and Obesogammarus crassus invaded the lower Vistula
The Echinogammarus berilloni-group, a number of predominantly Iberian Amphipod species (Crustacea)
The morphological diversity within the species Echinogammarus berilloni (Catta, 1878), stressed by Spandl (1926), Margalef (1956) and Pinkster (1969) was a motive to sample systematically in drainage
The predatory impact of the freshwater invader Dikerogammarus villosus on native Gammarus pulex (Crustacea: Amphipoda): influences of differential microdistribution and food recources
TLDR
Although differential microdistribution of the two species could promote coexistence, the presence of alternative foods/prey resources, merely slow the rate of IGP and replacement of the native by the invader.
Distribution and microhabitats of native and non-native gammarids (Amphipoda, Crustacea) in Brittany, with particular reference to the endangered endemic sub-species Gammarus duebeni celticus
TLDR
A decline in the endangered G. duebeni celticus is revealed, suggesting that the decline of the endemic species may be due to changes in the environment and/or interference from native G. pulex, which is expanding its range in Brittany.
MOUTHPART-ATLAS OF ARCTIC SYMPAGIC AMPHIPODS—TROPHIC NICHE SEPARATION BASED ON MOUTHPART MORPHOLOGY AND FEEDING ECOLOGY
TLDR
Evaluating the trophic niches of the four amphipod species by analysing the morphology of mouthparts and accessory feeding appendages and compiling all information available on species distribution and feeding ecology concludes that each species has evolved a specificTrophic strategy in selecting a different set of primary and supplemental food sources.
MOUTHPARTS OF THE PONTO-CASPIAN INVADER DIKEROGAMMARUS VILLOSUS (AMPHIPODA: PONTOGAMMARIDAE)
TLDR
Its ability to be carnivorous and to use a wide spectrum of other food may be an important reason for the success of this invader, being an advantage compared to mainly herbivorous gammarideans, which have been eliminated in many places by D. villosus.
Comparative ecology of Gammarus pulex (L.) and Asellus aquaticus (L.) I: population dynamics and microdistribution
TLDR
Differences in the dynamics of the two A. aquaticus populations were possibly a consequence of coal-mine and organic pollution, reducing the survival of offspring in the allopatric population.
Gammarids in Lake Constance : habitat segregation between the invasive Dikerogammarus villosus and the indigenous Gammarus roeselii
TLDR
It is hypothesized that a higher variability of substrates in the littoral zone of Lake Constance, compared to that found in most European waterways, allows coexistence of these two species.

TLDR
The Gammarus pulex-group is revised, based on rich material from Europe, North Africa, Asia minor and adjacent areas, and certain stable characters can be distinguished within some taxa, such as the structure of the mandibular palp.
