Preliminary Analysis of Hemocyanins in Hemolymph Plasma of Baikal Endemic Amphipods [PDF]

Journal of Stress Physiology & Biochemistry, 2016
Two-dimensional electrophoresis of plasma hemolymph proteins of several endemic Baikal amphipod species showed that, as expected, hemocyanin is the main major protein in plasma of these species.

Monthly differences in the movement ecology of lake whitefish (Coregonus clupeaformis) in eastern Lake Ontario

Journal of Fish Biology, EarlyView.
Abstract Lake whitefish are a cold‐water species that holds cultural and economic importance throughout the Great Lakes region. Anthropogenic stressors over the last 60 years (e.g., invasive species, habitat degradation, and pollution) have caused significant declines in their populations.

Small HSPs molecular weights as new indication to the hypothesis of segregated status of thermophilic relict Gmelinoides fasciatus among baikal and palearctic amphipods [PDF]

Journal of Stress Physiology & Biochemistry, 2011
Among the great diverse of Baikal fauna of amphipods (more than 350 species and subspecies) Gmelinoides fasciatus (Stebbing 1899) takes the special place. It is characterized by a high morphological variability and wide thermal-adaptive possibilities. By

Spatial habitat partitioning enables coexistence of three Gobiidae species in estuarine environments

Journal of Fish Biology, EarlyView.
Abstract This study examines resource partitioning (feeding morphology, diet and habitat partitioning) among three gobiid species, the Knysna sandgoby Psammogobius knysnaensis, the prison goby Caffrogobius gilchristi and the river goby Glossogobius callidus, within an estuarine environment.

Abundance, distribution and feeding patterns of a temperate reef fish in subtidal environments of the Chilean coast: the importance of understory algal turf Abundancia, distribución y patrones alimentarios de un pez de arrecifes templados en ambientes submareales de la costa de Chile: la importancia de la capa de algas del subdosel

Revista Chilena de Historia Natural, 2002
Cheilodactylus variegatus is an abundant carnivorous demersal reef fish that lives in the shallow subtidal of the north-central Chilean coast. Characteristically, these environments are dominated by kelp forests of Lessonia trabeculata.

Polar cod Boreogadus saida occurrence is driven by temperature at the margin of its distribution

Journal of Fish Biology, EarlyView.
Abstract With a warming Arctic, suitable habitat for polar cod Boreogadus saida (Lepechin 1774) is predicted to decrease. We investigated the changes in distribution of polar cod on the southern limit of its distribution in the Atlantic Ocean (around Iceland) during both autumn and spring after a recent period of warming in the area.

Microbial mats as shelter microhabitat for amphipods in an intermittent karstic spring

Knowledge and Management of Aquatic Ecosystems, 2018
Microbial mats represent complex communities where cyanobacteria and diatoms as key organisms provide shelter for diverse assemblages of aquatic invertebrates, like the small stygophilous amphipod Synurella ambulans.

Microsporidian Parasites Found in the Hemolymph of Four Baikalian Endemic Amphipods

PLoS ONE, 2015
At present, approximately 187 genera and over 1300 species of Microsporidia have been described, among which almost half infect aquatic species and approximately 50 genera potentially infect aquatic arthropods.

Filter feeders living on suspension feeders: New insights into the lifestyle and distribution of Arcturidae Dana, 1849 (Crustacea: Isopoda) around Iceland

Marine Ecology, EarlyView.
Abstract The focus of the present study was on arcturid isopods occurring in the subarctic region around Iceland. Data from two decades of sampling with an epibenthic sledge (EBS) during numerous expeditions of the BIOICE (Benthic Invertebrates of Icelandic Waters; 1992–2004) and IceAGE (Icelandic marine Animals: Genetics and Ecology; 2011—ongoing ...

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...
