Integrating adult occurrence and reproduction data to identify conservation measures for amphibians.

Monitoring programs are pivotal to establishing sound management. Due to economic, logistic, and time limitations, monitoring programs often overlook differences among life-history stages. However, species occurrence does not necessarily mean population viability, and it is unclear to what extent monitoring programs that do not consider separately adult presence and reproduction provide effective management indications.

First record of sponge distribution in the Persian Gulf, (Hengam Island, Iran).

The present study is a first attempt to examine sponge distribution in the Persian Gulf (Iranian costs) and suggests that physical and biological factors influence the sponge distribution patterns in Hengam Island. The purpose of this study is to provide patterns of sponges distribution and depth influence on sponge abundance and biomass on the Hengam Island. Surveys of sponge distribution were conducted June 2006 and February 2007 at 5, 10, 15 and 20 m depths sites in two locations: East and West of the Hengam island.
