INTRODUCTION The Frank Street catchment is an urbanised area on the Gold Coast located between Loders Creek and Biggera Creek, and drains directly to the Southport Broadwater. It has long been recognised that the capacity of drainage systems in the Frank Street area is minimal, primarily due to the aging drainage infrastructure. Most of the drainage systems were constructed prior to 1987 (when ...

To study the distribution of molluscs in the Riacho Fundo Creek (cerrado region of central Brazil), five creek sites were sampled once every two months for one year. Molluscs were sampled using standardized kick-net sampling. Four species of molluscs were found: Physella cubensis, Melanoides tuberculata, Biomphalaria straminea and Pisidium sp. The most abundant were P. cubensis and Pisidium sp....

Fish stocking (artificial supplementation) has been used to augment populations and angling opportunities. However, genetic composition and adaptations of native fish populations may be affected, raising management concerns. From 1995 to 2000, the New York State Department of Environmental Conservation stocked Walleye Sander vitreus fry and fingerlings from the Maumee River (western Lake Erie) ...

The tributaries of Lake Whatcom, Austin/Beaver, Anderson, Olsen, and Smith Creeks, provide essential habitat for many fish species native to the Pacific Northwest. However, development in the watershed has contributed to habitat alterations and even degradation of habitat quality. In this report, fish abundance and diversity, and habitat quality is compared both temporally, and among different ...

Most arthropod-borne viruses (arboviruses) show distinct serological subtypes or evolutionary lineages, with the evolution of different strains often assumed to reflect differences in ecological selection pressures. Buggy Creek virus (BCRV) is an unusual RNA virus (Togaviridae, Alphavirus) that is associated primarily with a cimicid swallow bug (Oeciacus vicarius) as its vector and the Cliff Sw...
