Integrating Biological Architecture and Biomaterial Function: Exploring the Native Hydrogel Structure of Brown Seaweed

Macromolecular Bioscience, Volume 26, Issue 4, April 2026.
This study explores the natural internal structure of brown seaweed and how it influences material behavior. By preserving and reassembling the seaweed's native architecture, hydrogels and foams with high liquid absorption, porosity, and shape recovery were created using minimal processing.

The effects of warming on the ecophysiology of two co-existing kelp species with contrasting distributions [PDF]

, 2017
The northeast Atlantic has warmed significantly since the early 1980s, leading to shifts in species distributions and changes in the structure and functioning of communities and ecosystems.

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

Oikos, Volume 2026, Issue 4, April 2026.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

Factors affecting estuarine populations of Nereocystis luetkeana in Kachemak Bay, Alaska [PDF]

, 2003
Thesis (M.S.) University of Alaska Fairbanks, 2003Nereocystis luetkeana forms extensive kelp beds in Kachemak Bay, Alaska. Salinity and turbidity gradients apparently regulate kelp bed distribution throughout this estuary.
