More recently, Zickovich and Bohonak (2007) compared genetic diversity ofpopulations ofthe amphipod
, Hyalella azteca, in perennial and intermittent streams in the semiarid region of southern California.
While several Arctic amphipod
species are endemic to the multi-year sea ice cover of the central Arctic Ocean, benthic species like Onisimus litoralis are common in nearshore seasonal ice regimes (Carey and Boudrias, 1987; Weslawski et al.
While some amphipod
species that inhabit shallow bays and basins have increased in abundance since Dreissena became established, partly because they can feed on mussel biodeposits, in theory, Diporeia does not feed on this material but depends more on freshly-settled phytoplankton (mostly diatoms).
The alien amphipod
had colonized several experimental mesocosms, but despite intensive sampling throughout the ice-free season, the species was not observed in regular monitoring stations (Kotta et al.
The taxa showing the statistically greatest abundances were 1) the corophiid amphipods
(mostly Paracorophium hartmannorum), 2) Diptera: Chironomidae, 3) bryozoans, and 4) lake plants (Multiple Comparison Kruskal-Wallis test, p<0.

, Winteria and a "Dumbo" Octopus; SEA MONSTER: The hideous Angler Fish has razor-sharp teeth
Laboratory feeding assays and amphipod
densities in the tanks suggested that the significant effects of amphipods
were attributable largely, if not exclusively, to the single amphipod
species Ampithoe longimana, which fed heavily on brown macroalgae.
We explored the effect of temperature on the anti-predator behavior of a keystone freshwater invertebrate, the amphipod
Except for October, amphipod
abundance was high in the southern inshore zone, in May it was 14,599 ind 1000 [m.
During feeding trials, a single amphipod
of adult size (>8 mm) was placed in a petri dish (9 cm diameter, Experiment 1) or a weigh boat (3 cm diameter, Experiment 2) with one disk of either ash or buckthorn.
Smith, 1873); grass shrimp Palaemonetes vulgaris; the amphipod
In addition to a single species of calanoid crustacean, at least 2 species of amphipod
In the current study we experimentally manipulated the presence of the filamentous macroalga Cladophora glomerata, the invasive amphipod
Gammarus tigrinus, the native prawn P.
Chelura terbrans, which lives within burrows made by Limnoria, and the copepod Tisbe gracilis, which occurs on wood blocks, ingests wood under laboratory conditions.
The key players in the Global Hydration Belts Market are Amphipod
