Combined impact of ultraviolet radiation and increased nutrients supply: A test of the potential anthropogenic impacts on the benthic amphipod Amphitoe valida from Patagonian waters (Argentina)

Frontiers in Environmental Science, 2014
Experiments were conducted during the Austral Summer of 2014 to determine the effects of increased nutrient input and ultraviolet radiation (UVR) on the food consumption rate (FCR) and food preference in the amphipod Amphitoe valida.

Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

Limnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Progress in the discovery of amphipod crustaceans

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 in Miocene amber and are probably all freshwater species.

Uptake, metabolism, and bioremediation of neonicotinoid insecticides in soil–plant systems: A review

New Plant Protection, EarlyView.
This review summarizes the uptake and metabolic transformation of neonicotinoid insecticides in plants, showing that some metabolites exhibit higher toxicity. We also critically assess promising bioremediation strategies using microbes and plant–microbe interactions to reduce residue contamination.

Structural variation in the brown alga Sargassum cymosum and its effects on associated amphipod assemblages

Brazilian Journal of Biology
The presence of diverse biological substrates adds complexity to coastal landscapes and increases the number of ecological niches that can be used by the mobile epifauna. Studies on the influence of structural complexity have focused mainly on algal host

Dynamic response of communities and ecosystem functions to ecosystem engineering and multiple stressors in a marine mussel bed

Oikos, EarlyView.
Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

Two Newly Recorded Species of the Genus Aoroides (Crustacea: Amphipoda: Aoridae) from Korea [PDF]

Animal Systematics, Evolution and Diversity, 2016
Two aorid amphipods, Aoroides ellipticus Ariyama, 2004 and A. semicurvatus Ariyama, 2004 from shallow waters of South Korea are reported here. Aoroides ellipticus has the characteristic setation of gnathopod 1 and the elliptical shape of basis on ...

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers

Oikos, EarlyView.
Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.
