A curated review of ESA publications for teaching ecology

The Bulletin of the Ecological Society of America, EarlyView.
Abstract Since the early 1990s, the Ecological Society of America's journals have published hundreds of articles of direct relevance to those who teach ecology—especially at the undergraduate level. In an effort to draw attention to that literature, we conducted an analysis to identify well‐cited articles, as well as those that may be underrecognized ...

Harnessing blood clot as a native scaffold for orchestrating tissue repairs and regeneration

BMEMat, EarlyView.
The blood clot, owing to its dynamic composition and unique microenvironment, holds significant yet underappreciated potential for tissue engineering. This review systematically summarizes the pathophysiology of clot formation, the key regulatory factors shaping its microenvironment, and its applications in both pre‐clinical and clinical settings ...

Recolonisation of spawning grounds in a recovering fish stock: recent changes in North Sea herring

Scientia Marina, 2009
There is evidence that the importance of the different spawning grounds of North Sea autumn-spawning herring has changed. It has been hypothesised that as herring stocks collapse, the diversity of spawning sites also collapses.

The influence of rivers on seabird foraging ecology

Biological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...
