wfrc.usgs.gov — The objective of this research is to determine if symbiotic fungi are responsible for the invasiveness of plants in non-native habitats. One of the least studied but critical aspects of plant community structure and dynamics involves symbiotic interactions with endophytic and mycorrhizal fungi. In the last several decades it has become apparent More...

wfrc.usgs.gov — Ballast water discharges are the most significant cause of aquatic biological invasions in coastal waters, including the Great Lakes. Currently, treatment of ballast water prior to discharge at the receiving port offers significant promise to help control this problem. However, development of treatment technologies is limited by lack of objective More...

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...

fresc.usgs.gov — Periodic fire is a natural part of sagebrush steppe ecosystems in the Great Basin. However, a suite of human-caused factors has dramatically changed fire regimes in many of these systems. Decades of fire suppression and livestock grazing have produced dense, single-aged sagebrush stands and invasion by cheatgrass (Bromus tectorum) has increased 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...
