The role of epiphytic algae and different species of Sargassum in the distribution and feeding of herbivorous amphipods

Latin American Journal of Aquatic Research, 2014
The presence of particular algal species can directly influence the distribution and abundance of mesoherbivores. The aim of this study was to answer the following questions: Do Sargassum beds of different localities show variation in the load of ...

Climate Change and invasibility of the Antarctic benthos [PDF]

, 2007
Benthic communities living in shallow-shelf habitats in Antarctica (<100-m depth) are archaic in their structure and function. Modern predators, including fast-moving, durophagous (skeleton-crushing) bony fish, sharks, and crabs, are rare or absent ...

Functional characterization of 42 CK2α de novo variants associated with Okur‐Chung neurodevelopmental syndrome

The FEBS Journal, EarlyView.
Okur‐Chung neurodevelopmental syndrome (OCNDS) is a neurodevelopmental disorder associated with mutations in the gene coding for Protein kinase CK2α. In this work, 42 variants of CK2α associated with OCNDS were characterized in vitro. This included determination of catalytic activity and CK2α/CK2β‐interaction as well as an assessment of evolutionary ...

Decadal Rapid Change in Energetic Carrying Capacity for Juvenile Chum Salmon in the Sanriku Coast

Fisheries Oceanography, EarlyView.
ABSTRACT Adult returns to coastal rivers in Sanriku, located near the southernmost area of chum salmon distribution, have declined since 2010. Climate‐induced fluctuations in juvenile prey availability may affect growth and survival, which are linked to adult returns.

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.

The influence of a cooling water system on waterbird habitat use in a coastal environment

Ibis, EarlyView.
This study investigated the impact of a cooling water system at a nuclear power plant in northern Europe on coastal waterbird habitat use. In winter, the cooling water system provided preferential areas for waterbirds with warm productive waters, and, more importantly, with ice‐free areas.

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.

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
