Abundance and diversity of amphipod crustaceans in the Upper Songkhla Lagoon [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2007
A bimonthly investigation of amphipod crustaceans in the Upper Songkhla Lagoon from April 2003 to February 2004 was undertaken to determine the abundance and species richness.

Investigating Sex‐Biased Dispersal in a Vulnerable Marine Invertebrate, the European Spiny Lobster (Palinurus elephas)

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Does dispersal differ between the sexes? Our findings underscore the power of genomic markers to study sex‐biased dispersal, elucidate sex determination systems, and facilitate sex assignment, with important implications for species conservation and management. ABSTRACT Does dispersal differ between the sexes?

Oases of endemism: Regional aquifer desert springs serve as biodiversity hotspots preserving vulnerable endemic taxa in the Great Basin and Mojave Desert regions

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Spring ecosystems in arid regions often serve as crucial biodiversity hotspots by providing some of the only reliable sources of surface water. However, anthropogenic activities and climate change have severely degraded spring ecosystems worldwide, emphasizing the need for large‐scale multidisciplinary studies informing conservation efforts ...

Amphipod family distributions around Iceland

open access: yesZooKeys, 2018
Amphipod crustaceans were collected at all 55 stations sampled with an epibenthic sledge during two IceAGE expeditions (Icelandic marine Animals: Genetics and Ecology) in 2011 and 2013. In total, 34 amphipod families and three superfamilies were recorded

Marine invertebrates and fishes exhibit inconsistent body size responses to ocean acidification

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Body size is a fundamental characteristic of all living organisms that determines physiological functions and life‐history traits. Ecological theory predicts that ocean acidification can cause body size reductions, confirmed by several studies reporting miniaturization in ectotherms.

Innervation of an amphipod heart [PDF]

open access: yesJournal of the Marine Biological Association of the United Kingdom, 1954
SummaryIn the heart of Marinogammarus marinus three systems of nerve elements have been found, viz. (1) a local system consisting of a ganglionic trunk situated on the dorsal surface of the heart and sending branches to the muscle fibres, (2) two paired nerves, termed the 1st and 2nd cardiac nerves, connecting the local system with the central nervous ...

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 ...

Mass Die‐Off Events in Swarming Hyperiid Amphipods: Potential Drivers

open access: yesEcology and Evolution
Beach mass stranding events of marine organisms, widely documented worldwide, are triggered by a range of biotic and abiotic environmental factors, often unexplained. Such occurrences among pelagic crustaceans are less frequent, yet not uncommon. Here we

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.

From darkness to twilight: Morphological divergence between cave and surface‐subterranean ecotone Niphargus species

open access: yesEcology and Evolution
Subterranean and surface habitats are in stark contrast in several environmental factors. Therefore, adaptation to the subterranean environment typically impedes the (re)colonisation of surface habitats.
