Climate variability in regions of amphibian declines
Article Abstract:
The possibility that variation in climate was correlated with amphibian declines at specific locations like Colorado, Puerto Rico through two sources of data is studied. The results indicate that the unusual climate is unlikely to be the cause of amphibian decline directly even though an indirect impact is not ruled out and the most likely pathogen is a chytrid fungus, which does not produce desiccation-resistant spores.

Effects of upstream diversion of Colorado River water on the Estuarine Bivalve Mollusc Mulinia coloradoensis
Article Abstract:
Studies done on the composition and geochemistry of subfossil shells dating from before the Colorado's diversion is presented. The relative abundance of empty shells of the bivalve mollusc Mulinia coloradoensis decreases with increasing distance from the mouth of the Colorado River, indicating that M.coloradoensis was dependent on the flow of the river.

Catastrophic Decline in Mollusc Diversity in Eastern Tasmania and Its Concurrence with Shellfish Fisheries
Article Abstract:
Sediment core samples demonstrate the significant decline of Tasmanian mollusk populations between 1890 to 1990, with a mean decline from 21 species to 7 species. The data are evaluated in light of continued fishing and anthropogenic impacts along Tasmania's coast, and implications for conservation are discussed.
