Managing native and non-native sea lamprey (Petromyzon marinus) through anthropogenic change: A prospective assessment of key threats and uncertainties

Sea lamprey (Petromyzon marinus) is a species of conservation concern in their native range the Atlantic coasts Europe (Near Threatened to Critically Endangered) and North America (Secure Imperiled), an invasive great economic ecological Laurentian Great Lakes. Despite differences life history strategy (anadromous natives vs adfluvial non-natives), biology sea sufficiently similar expect comparable responses large-scale environmental change. We take prospective look at future (50 100 years) management era considerable disturbance, consider biological responses, actions, status populations across non-native ranges. Based on facilitated discussion by diverse group international experts, two major but poorly characterized classes threats were identified: climate change socio-political issues. discuss how induced changes affect growth, bioenergetics, phenology lamprey, associated effects control tactics (pesticides barriers) conservation. tensions surrounding improving connectivity Lakes while controlling supplements alternatives pesticides wider effect, as well new species. To prevent extirpation populations, or re-expansion we conclude with call for ongoing dialogue collaboration among all biologists managers range.
