Parasites' impact goes beyond host to affect ecosystem
...thesized that since L. littorea was the intertidal zones most voracious eater of green, weedy algae, and the flatworm C. lingua infects L. littorea and damages its digestive system, then perhaps C. lingua infection could alter the abundance of this ephemeral macroalgae.

...El Nino. In addition, the two sites are located in zones which are tectonically quiet unlike volcanic islands and continental margins. This is the rational behind the CHECREEF proposal. However, Camoin goes on to say that to get a clear picture and a very good dataset, it is necessary to investigate other ...Study warns deep-sea mining may pose serious threat to fragile marine ecosystems
...cosystems that lie within other countries economic zones or in international waters. This poses additional problems, because while a state has the right to exploit its own resources, international environmental law decrees that it cannot damage the environment beyond its boundaries.

It analyzed burn severity patterns with a commonly used metric of fire damage on almost 45,000 acres of the Biscuit Fire that had also burned 15 years earlier.
