Radionuclides in arctic marine macroalgae from Kongsfjorden (Svalbard) [PDF]

open access: yes, 2018
Seaweeds are known to be useful environmental bioindicators since they bioaccumulate radioisotopes at very low environmental concentrations. Levels of natural radionuclides in six ecologically relevant brown and red seaweed species from Arctic coasts ...

Commercially important seaweeds of India, their occurrence,chemical products and uses [PDF]

open access: yes, 1991
The seaweeds form one of the important marine living resources. They are primitive type of plants growing in the intertidal or sub-tidal regions of the sea. They flourish wherever rocky or coral substratum is available for their attachment with the help

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

open access: yesEcography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

The effect of trait choice on hybrid species distribution model projections under climate change

open access: yesEcography, EarlyView.
Species distribution models (SDMs) have been increasingly combined with thermal performance data to enhance their transferability and to provide a physiological explanation for the predicted geographic patterns. Yet, while it is widely acknowledged that thermal sensitivities may vary among biological traits, it remains largely unexplored to what extent
