A new study from Southern California affirms that the long-standing management practice of beach grooming is contributing to the loss of coastal strand habitat. Coastal strand plant communities grow along the edge of the high tide line and are comprised largely of endemic species adapted to grow in the dynamic, environment of loose, shifting sand......

Results from a new study in Australia affirm the ability of "no take" marine protected areas to aid the recovery of overfished ecosystems. Researchers found that the reefs within three marine protected areas off eastern Tasmania transformed over time into communities not otherwise seen in the regional seascape, and these changes intensified for at least 16 years....

We interview Dr. Eugene Turner, a leading wetland scientist at Louisiana State University. He argues that restoration practitioners need to abandon a knowledge-based world view and start embracing ignorance...... Read more »

If you ever walked along an empty stretch of beach and flushed away a flock of frightened shore birds, you might have wondered to yourself whether you just committed a horrible ecological sin.
Perhaps you asked yourself, "Where are those birds going? Did they just abandon their nestlings? How long until they come back? Or better yet, will they ever come back?"
A new study tries to answer these types of questions with respect to the impact of recreational boaters on nesting colonies of black skimmers in New Jersey where the birds are listed as endangered. As it turns out, the answers can help coastal managers develop scientifically informed regulations such as setting no-entry buffer zones around nesting colonies to minimize human impact....

Vacation homes may be harming some birds through increased nest predation, according to the findings in a new study in the journal of European Wildlife Research.
While suburban sprawl receives close scrutiny for its negative environmental impacts, vacation homes and other low density housing in more pristine areas are often overlooked.
However, as Ole-Gunnar Støen and fellow researchers in Norway show, these homes can negatively impact birds by attracting generalist predators that feed on nest eggs.... Read more »
