A field test on the effectiveness of milfoil weevil for controlling Eurasian watermilfoil in Wisconsin lakes

Autor: Kristopher A. Maxson, Susan E. Knight, John E. Havel

Publikováno v: Hydrobiologia. 800:81-97

We tested the effectiveness of milfoil weevils (Euhrychiopsis lecontei) for reducing biomass of Eurasian watermilfoil (Myriophyllum spicatum, EWM) under natural lake conditions in a 3-year field experiment. In each of four lakes, we randomly chose tw

Using maximum entropy to predict the potential distribution of an invasive freshwater snail

Autor: Monica Papeş, John E. Havel, M. Jake Vander Zanden

Publikováno v: Freshwater Biology. 61:457-471

SUMMARY 1. Ecological niche modelling is a technique used to estimate potential distributions of invasive species based on available occurrence data and associated environmental conditions. Maximum entropy (Maxent) is a powerful method for ecological

Potential Impacts of Stream Crossing Traffic On Macroinvertebrate Communities in the Missouri Ozark River

Autor: R. L. S. Heth, John E. Havel, D. E. Bowles

Publikováno v: River Research and Applications. 32:925-934

Depending on intensity, physical disturbance can either decrease or increase diversity of stream macroinvertebrate communities. Recreational activities in parks are one component of physical disturbance. Our objective was to evaluate the effects of s

Aquatic invasive species: general trends in the literature and introduction to the special issue

Autor: Lee B. Kats, Katya E. Kovalenko, John E. Havel, Sidinei Magela Thomaz

Publikováno v: Hydrobiologia. 746:1-12

Invasion rates are increasing worldwide and most are due to the actions of humans. Deliberate introductions, escapes, and hitchhiking with global commerce transport species to other continents. While most species fail to thrive or have minor impacts

Survival of invasive aquatic plants after air exposure and implications for dispersal by recreational boats

Autor: Lindsey A. Bruckerhoff, Susan E. Knight, John E. Havel

Publikováno v: Hydrobiologia. 746:113-121

Recreational boating is widely recognized as an important vector for overland transport of invasive aquatic plants. Since their dominant form of recruitment is vegetative reproduction, entangled fragments on boats and trailers can establish new popul

Resistance to desiccation in aquatic invasive snails and implications for their overland dispersal

Autor: Adrienne R. Gemberling, Lindsey A. Bruckerhoff, Meghan A. Funkhouser, John E. Havel

Publikováno v: Hydrobiologia. 741:89-100

At least 30 species of nonindigenous freshwater snails have invaded North America. The risk of these snails invading new lakes depends upon their ability to survive overland transport. We first reviewed published laboratory experiments using freshwat

Publikováno v: Aquatic Sciences. 73:419-436

Main channel habitats of the Ohio, Missouri, and Upper Mississippi Rivers were surveyed during the summers of 2004, 2005 and 2006 using a probability-based sampling design to characterize inter-annual and inter-river variation in suspended chlorophyl

Survival of the exotic Chinese mystery snail (Cipangopaludina chinensis malleata) during air exposure and implications for overland dispersal by boats

Autor: John E. Havel

Publikováno v: Hydrobiologia. 668:195-202

The exotic Chinese mystery snail (Cipangopaludina chinensis malleata) has invaded lakes and rivers across North America and is particularly widespread in northern Wisconsin. Although deliberate introductions and aquarium releases have likely been imp
