Genome Reduction in Psychromonas Species within the Gut of an Amphipod from the Ocean’s Deepest Point

mSystems, 2018
Amphipods are the dominant scavenging metazoan species in the Mariana Trench, the deepest known point in Earth’s oceans. Here the gut microbiota of the amphipod Hirondellea gigas collected from the Challenger and Sirena Deeps of the Mariana Trench were ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Swarms of Amphipods [PDF]

Nature, 1893
ONCE last winter on entering the laboratory here after it had been shut up for a few days, we found the floor, tables, shelves, window-ledges, and even dishes on the highest shelves, covered with great numbers of dead amphipods. These were found to be Orchestia gammarellus (the shore-hopper).

The effects of single versus successive warm summers on an intertidal community

Oikos, EarlyView.
To accurately predict how organisms and ecological communities will respond to future conditions caused by climate change, we must consider the temporal dynamics of environmental stressors, including the effects of repeated exposures to stress. We performed a two‐year passive thermal manipulation in coastal British Columbia, Canada to determine how ...

Swarming of Hyperiid Amphipods [PDF]

Nature, 1967
FOLLOWING a period of moderately strong westerly wind, on June 26, 1966, the beaches of Robin Hood's Bay, Filey, and Sandsend, Yorkshire (extending for about 40 km of coastline), were turned white by a covering of vast numbers of hyperiid amphipods.

Ecological Characteristics of Stream Reaches With and Without Low‐Tech Process‐Based Restoration in a Wildfire‐Affected Catchment

River Research and Applications, EarlyView.
ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

Individualised niches in a variable environment—Consequences for environmental change responses

Methods in Ecology and Evolution, EarlyView.
Abstract Intraspecific trait variation (ITV) can be important for population performance in a variable and changing environment because individuals with different traits have different fitness responses. Furthermore, there are three mechanisms via which individuals can interact with their environment to potentially improve fitness: niche conformance ...

Baikal amphipod (Gmelinoides fasciatus) and is contribution to the feeding of Ladoga Lake perch [PDF]

BIO Web of Conferences
The feeding of perch (Perca fluviatilis) from the littoral zone of Ladoga Lake was studied. Attention was focused on the colonizer species, a Baikal amphipod (Gmelinoides fasciatus), and its contribution to feeding.

Progress in the discovery of amphipod crustaceans [PDF]

PeerJ, 2018
At present, amphipod crustaceans comprise 9,980 species, 1,664 genera, 444 subfamilies, and 221 families. Of these, 1,940 species (almost 20%) have been discovered within the last decade, including 18 fossil records for amphipods, which mostly occurred ...

Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

Acta Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...
