The Ecology contribution to address this question is to determine possible physicochemical impacts on 1) pond water quality and biological integrity, and 2) avulsed pit pond water quality and biological integrity in the historical pit location and receiving waters. These questions will be addressed by all study partners together in a more comprehensive fashion after the interim phase of reporting.

Oxidative stress has been identified as a crucial factor leading to male infertility largely due to peroxidativedamage to the sperm cell membrane. Cadmium (Cd) is a widespread environmental pollutant and oneof the well-known reproductive toxicants. Because of its long biological half-life (10–30 years), Cdaccumulates in the biological systems. The present study was designed to assess the concen...

Long-term changes of fish biotic integrity in the Sanmenxia Wetland, North China, since the 1950s were assessed using the fish index of biological integrity (FIBI). The water and sediment quality was evaluated by the water quality index (WQI) and sediment pollution index (SPI). The results showed that FIBI continuously decreased from 46 to 20 during the past 5 decades, which indicated that the ...

The Clean Water Act mandates that the chemical, physical, and biological integrity of our nation's waters be maintained and restored. Physical integrity has often been defined as physical habitat integrity, and as such, data collected during biological monitoring programs focus primarily on habitat quality. However, we argue that channel stability is a more appropriate measure of physical integ...

The National Wildlife Refuge system is a vital resource for the protection and conservation of biodiversity and biological integrity in the United States. Surveys were conducted to determine the spatial and temporal patterns of fish, macroinvertebrate, and crayfish populations in two watersheds that encompass three refuges in southern Indiana. The Patoka River National Wildlife Refuge had the h...

We present an approach to model adaptive, dynamic hybrid control systems based on behaviour networks. We extend and modify the approach to behaviour networks with integrity constraints, non-ground rules, internal actions, and modules to make it self-adaptive and dynamic. The proposed approach is general, reconfigurable, robust, and suitable for environments that are dynamic and too complex to b...
