Gammarus pulex is a species of amphipod crustacean found in fresh water across much of Europe. It is a greyish animal, growing to 21 mm (0.83 in) long. Adult males of Gammarus pulex may reach a total length of 21 millimetres (0.83 in), while females only grow to 14 mm (0.55 in). [1] .

蚤状钩虾（Gammarus pulex）：端足目，是本目少数淡水种的代表，体长11mm---24mm。 分布欧亚大陆的非热带地区以及 北美，南非。 我国各地均产，在水草繁茂的水域尤其常见。 蚤状钩虾（Gammarus pulex）：端足目，是本目少数淡水种的代表，体长11mm---24mm。

As a result, although both native and invasive amphipods are used by the parasite, native G. pulex/G. fossarum are more important to the parasite dynamics and can be considered a key host for P. laevis (Bauer and Rigaud, 2015).

2023年6月10日 · Alterations in drifting behavior may have important implications for G. pulex population dynamics and microsporidians’ dispersal. The underlying mechanisms are more complex than previously...

2016年3月23日 · We tested the hypotheses that (1) Gammarus pulex, a widespread detritivore, migrates into the hyporheic zone to avoid increasing surface water temperature and intraspecific competition and (2) that these factors would reduce their …

Gammarus pulex is a species of amphipod crustacean found in fresh water across much of Europe. It is a greyish animal, growing to 21 mm long. Adult males of Gammarus pulex may reach a total length of 21 mm, while females only grow to 14 mm. The adults have a robust appearance; they are typically greyish with markings in dark brown or green.

2015年2月7日 · We conducted a laboratory experiment to examine the effects of FS on the movement of Gammarus pulex Linnaeus (Crustacea: Amphipoda) into subsurface sediments in response to surface water loss. We hypothesized that increasing volumes of FS would impede and ultimately prevent individuals from migrating into the sediments.

G. pulex population dynamics and microsporidians’ dispersal. The underlying mechanisms are more complex than previously thought. Dispersal is a pervading feature of most animals and has an...

To explore it, we studied the effects of LMB on the macroinvertebrate Gammarus pulex. In a 3-day habitat choice trial, compared with the pebbles covered with sand, bentonite or LMB, G. pulex preferred the uncovered pebbles. In a 4-day acute toxicity trial, one death was found in the 500, 1000 and 2000 g m-2 LMB treatments, respectively. In a 7 ...

Gammarus pulex and Asellus aquaticus generally occupy different zones in rivers; the former occurs in upper reaches but is ‘replaced’ by the latter in lower reaches. Microdistribution and life-history patterns of G. pulex and A. aquaticus in sympatry and allopatry, were analyzed.
