A landscape perspective
Article Abstract:
The richness of vascular plants species was significantly correlated with geomorphological heterogeneity in a study of 26 Audubon refuges in Rhode Island. Therefore, conservation of geomorphological diversity may be an effective method of biodiversity conservation. Measures of geomorphological heterogeneity included aspect heterogeneity, slope heterogeneity and diversity in soil drainage class. More than half the variance of plant species richness was accounted for by soil drainage variation alone.

Effects of otter trawling on a benthic community in Monterey Bay National Marine Sanctuary
Article Abstract:
Bottom trawling is considered the most disruptive and damaging human-induced physical disturbances to seabed communities with global consequences. Researchers studying fishing areas in Monterey Bay National Marine Sanctuary hypothesized that otter trawling reduces habitat complexity and biodiversity. Their study showed that high levels of trawling enhances the abundance of opportunistic species and reduces habitat biodiversity and complexity. .

Species redundancy and ecosystem reliability
Article Abstract:
Principles of reliability engineering suggest that species redundancy should be valued as an important element of ecosystems. Redundant species may enhance the reliability of ecosystem functioning. Reliability engineering thus points to a new way of looking at the relationship between biotic diversity and ecosystem viability. A formal definition is given of the role of species in the functioning of ecosystems.
