The lifecycles of parasites are often complex, with multiple successive hosts. Many parasites have evolved the ability to modify the behaviour of their present host to increase the chance of transmission to the next host. Few studies to date have considered how a suite of related behavioural traits in the host can be affected by parasitic manipulations. The present study investigated the effect...

Coastal protection, nutrient cycling, erosion control, water purification, and carbon sequestration are ecosystem services provided by salt marshes. Additionally, salt ponds offer coastal breeding and a nursery habitat for fishes and they provide abundant invertebrates, such as amphipods, which are potentially useful as a resource in aquaculture. Fishmeal and fish oil are necessary food resourc...

We used a freshwater amphipod-microsporidian model (Ponto-Caspian hosts: Dikerogammarus villosus and D. haemobaphes , parasite: Cucumispora dikerogammari ) to check whether parasites affect biological invasions by modulating behaviour intra- interspecific interactions between the invaders. tested competition for shelter in conspecific heterospecific male pairs (one or both individuals infected ...

Hadal trenches are commonly referred to as the deepest areas in ocean and characterized by extreme environmental conditions such high hydrostatic pressures very limited food supplies. Amphipods considered dominant scavengers hadal web. Alicella gigantea is largest amphipod and, such, has attracted a lot of attention. However, adaptive evolution gigantism mechanisms “supergiant” remain unknown. ...

Epibiotic associations can result in co-introductions of non-indigenous species, which may affect ecosystems several ways. In fouling communities three estuaries southern Brazil, a number amphipods was found to harbour dense coverage epibionts. Three different the two globally widespread caprellids Caprella equilibra and Paracaprella pusilla, as well ischyrocerid Jassa valida, had been colonise...
