www.umesc.usgs.gov — Zebra mussels have caused drastic declines in native clam and mussel populations in some locations. Zebra mussels compete with other invertebrates and young fish for plankton, the primary food source for these groups. UMESC scientists are investigating the effects zebra mussels are having on the riverine ecosystem. This study examines the effects More...

www.umesc.usgs.gov — Eurasian Ruffe pose a threat to native fish because they(1) mature quickly, (2) have a high reproductive capacity, and (3) easily adapt to new environments. Ruffe were first detected in western Lake Superior in 1986. UMESC scientists are conducting research on various types of piscicides (chemicals that kill fish). They are attempting to develop More...

wfrc.usgs.gov — The general objective of this collaborative project is to investigate and improve habitat-based ecological modeling on large rivers. While many ecological aspects of large-river alteration have been investigated previously, there has been little emphasis on how alterations of physical habitat interact with life histories, biotic interactions, and More...

www.umesc.usgs.gov — Gobies are capable of rapid population growth after they reach new areas. They have shown the ability to out-compete native fish for food and habitat. Another area of concern involves potential predation on the eggs and fry of lake trout. After first being discovered in 1990 along the St. Claire River (a Canadian river north of Detroit), gobies More...

www.werc.usgs.gov — Riparian vegetation is intimately linked to the stream and river channels along which it grows. This project addresses the status of the riparian zone along Redwood Creek north coastal California, and answers three questions: 1) How have the overstory riparian conditions changed in Redwood Creek and major tributaries since the advent of timber More...

www.nbii.gov — Natural resource managers face complex decisions that require a clear understanding of the status of wildlife populations and their habitats. Monitoring is key to making effective management decisions and evaluating the outcomes of those decisions. The goal of NRMP is to improve the accessibility of monitoring efforts to resource managers to aid More...

www.fort.usgs.gov — Natural Resource Monitoring Partnership (NRMP) is a collaborative effort by the natural resource management community to improve monitoring efforts in order to support effective evaluation and decision-making by sharing information on monitoring projects and protocols. The Natural Resource Monitoring Partnership was built for easy access to More...
