Biodiversity and Biogeography of Amphipod Crustaceans

open access: yes, 2020
This dissertation presents aspects of the taxonomy, biodiversity, and biogeography of amphipod crustaceans and is an attempt to address the significant knowledge gaps in the absence of global assessments of the diversity and biogeography of amphipods ...

Performance of a glider‐mounted multifrequency echosounder for measuring the vertical distribution and abundance of large pelagic copepods

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract The difficulty of sampling zooplankton communities in situ has driven advancements in autonomous, remote sensing technology. The goal of this paper was to perform a gear comparison study testing the performance of one such piece of technology—a glider‐mounted four‐frequency echosounder—against traditional shipboard methods of measuring ...

Variation of amphipod assemblage along the Sargassum stenophyllum (Phaeophyta, Fucales) thallus

open access: yesNauplius
The spatial distribution of fauna associated to marine macroalgae has mostly been investigated considering a horizontal plane. However, the macroalgal substrates can present a three-dimensional structure.

Feeding Ecology of Gould's Arrow Squid Nototodarus gouldi (Cephalopoda: Ommastrephidae) in Aotearoa New Zealand Waters

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Squids are important components of marine ecosystems because of their role as both predator and prey. Across the Tasman Sea, Gould's arrow squid (Nototodarus gouldi) is a commercially targeted ommastrephid squid that supports an economically important fishery.

Temporal variation of the gammaridean fauna (Crustacea, Amphipoda) associated with the sponge Mycale angulosa (Porifera, Demospongiae) in southeastern Brazil

open access: yesNauplius
Marine sponges are advantageous microhabitats because of their complex architecture. The system of internal canals provides circulation of water and deposition of particulate organic matter, ensuring availability of food and shelter. Diminutive amphipods

New marine amphipod records on the Algerian coast

open access: yes, 2014
International audienceRecent sampling surveys (2011-2012) of the shallow (0-50 m) hard-bottom communities and re-examination of some softbottom communities (5-143 m) along the Algerian coast have allowed the collection of 33 species (five Caprelloidea ...

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

open access: yesOikos, Volume 2026, Issue 6, June 2026.
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 ...

Species associations among larval helminths in an amphipod intermediate host

open access: yes, 2000
Larval helminths that share the same intermediate host may or may not also share the same definitive hosts. If one or more of these helminth species can manipulate the phenotype of the intermediate host, there can be great advantages or severe costs for ...

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

open access: yesRiver Research and Applications, Volume 42, Issue 5, Page 1022-1037, June 2026.
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

Efficacy of Clearflow Treatment Technologies in the Treatment of Mining Effluent: Field‐Level Testing at a Coal Mine

open access: yesEnvironmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Mining waste water characteristically contains high concentrations of suspended solids, total metals, and nutrients. These can be treated with flocculants within settling ponds to speed up the clarification of water by settling out the suspended solids.
