A long-term rusty crayfish (Orconectes rusticus) invasion: dispersal patterns and community change in a north temperate lake
Rusty crayfish (Orconectes rusticus) were first observed in Trout Lake, Wisconsin, in 1979 and took 19 years to completely disperse around the littoral zone, advancing at an average rate of 0.68Expand
Allopatric genetic origins for sympatric host-plant shifts and race formation in Rhagoletis
Tephritid fruit flies belonging to the Rhagoletis pomonella sibling species complex are controversial because they have been proposed to diverge in sympatry (in the absence of geographic isolation)Expand
HYBRID ZONE DYNAMICS AND SPECIES REPLACEMENT BETWEEN ORCONECTES CRAYFISHES IN A NORTHERN WISCONSIN LAKE
Abstract.— Hybrid zones that result in the genetic assimilation (replacement) of one species by another are underrepresented in the animal literature, most likely due to their transient nature. OneExpand
THE EFFECTS OF WINTER LENGTH ON THE GENETICS OF APPLE AND HAWTHORN RACES OF RHAGOLETIS POMONELLA (DIPTERA: TEPHRITIDAE)
Host plant‐associated fitness trade‐offs are central to models of sympatric speciation proposed for certain phytophagous insects. But empirical evidence for such trade‐offs is scant, which has calledExpand
Importance of hybridization between indigenous and nonindigenous freshwater species: an overlooked threat to North American biodiversity.
Biodiversity of North American freshwaters is among the greatest in the world. However, due to extensive habitat degradation, pollution, and introductions of nonindigenous species, this biodiversityExpand
Zebra Mussel Dispersal in Lake-Stream Systems: Source-Sink Dynamics?
We investigated the ability of zebra mussels (Dreissena polymorpha) to colonize small streams (<30 m wide), which have been considered to have low susceptibility to invasion. We examined EuropeanExpand
Implications of Hybridization between Introduced and Resident Orconectes Crayfishes
: One of the most imperiled taxonomic groups in North American freshwaters is that of crayfish ( Decapoda: Astacoidea): over 30% of the 390 species are threatened or endangered. This situation isExpand
Impact of crayfish predation on exotic zebra mussels and native invertebrates in a lake-outlet stream
To test the hypothesis that Orconectes spp. crayfishes could be a significant source of zebra mussel (Dreissena polymorpha) mortality in streams, we conducted a laboratory experiment and a fieldExpand
Effects of outreach on the awareness and adoption of conservation practices by farmers in two agricultural watersheds of the Mackinaw River, Illinois
Increased awareness of the contributions of nonpoint source runoff to the degradation of water quality in the Mississippi River and Gulf of Mexico emphasizes the need to increase conservationExpand
Quantifying nutrient removal from groundwater seepage out of constructed wetlands receiving treated wastewater effluent
Wetlands play an important role in the reduction of nutrients in agricultural runoff and treated wastewater effluent. A component of wetlands systems, the seepage out of the wetland and subsequentExpand
