The impact of turtle excluser devices and fisheries closures on loggerhead and Kemp's ridley strandings in the Western Gulf of Mexico

Article Abstract:

Results indicate that both sea turtle population growth and shrimping activity contribute to the increase in strandings. Deployment of turtle excluder devices induces variability in strandings, while low compliance leads to high level of strandings. Data indicae that improved deployment of turtle excluder devices reduces stranding levels, which in association with other protective measures promotes population recoveries of loggerheadn and Kemp's ridley turtles.

Recovery of native earthworms in abandoned tropical pastures

Article Abstract:

Research describes changes in earthworm diversity and community stucture at tropical pastures in the Cayey Mountains of Puerto Rico consisting of active pastures, 25-40 years old young secondary forests, and mature secondary forests. Results reveal that earthworm diversity increases along successional stages and that regeneration of mature secondary forests and litter biomass increase facilitate the recovery of diversity and native species of earthworms.

Effects of prescribed burning on amphibian diversity in a southeastern U.S. national forest

Article Abstract:

Nature conservation research in South Carolina's Francis Marion National Forest indicates that reducing prescribed-burn frequency from every two to three years to every three to seven years will improve biodiversity preservation among plant and amphibian populations. Specific data regarding population percentages is included.
