Paddlefish (Polyodon spathula): Growth and Food of Young of the Year and a Suggested Technique for Measuring Length
TLDR
The kinds of insects found in the stomachs suggested that the young fish fed at night in open water, near the surface, while the diet in 1972 consisted of zooplankton and aquatic and terrestrial insects.
Hydrologic variability and the application of Index of Biotic Integrity metrics to wetlands: A great lakes evaluation
Interest by land-management and regulatory agencies in using biological indicators to detect wetland degradation, coupled with ongoing use of this approach to assess water quality in streams, led to
FIRST RECORD OF NEOERGASILUS JAPONICUS (POECILOSTOMATOIDA: ERGASILIDAE), A PARASITIC COPEPOD NEW TO THE LAURENTIAN GREAT LAKES
TLDR
The parasitic copepod Neoergasilus japonicus appears to disperse over long distances rather quickly, spreading across Europe in 20 yr and then moving on to North America over a span of 10 yr.
Limitations to lake trout (Salvelinus namaycush) rehabilitation in the Great Lakes imposed by biotic interactions occurring at early life stages
TLDR
Evidence that biotic factors, particularly predation, may be limiting early survival of wild lake trout juveniles in many areas of the Great Lakes is examined and recommendations for research to better define field feeding rates of lake trout egg and fry predators are made.
Predator-Prey Relations and Competition for Food Between Age-0 Lake Trout and Slimy Sculpins in the Apostle Island Region of Lake Superior
TLDR
Investigation of the diets of age-0 lake trout and slimy sculpins on a lake trout spawning reef and adjacent nursery area in the Apostle Island region of western Lake Superior found coexistence of the two species appears amicable, but in other Great Lakes with higher sculpin to lake trout ratios on a reef, the coexistence may be a bottleneck for age- 0 lake trout survival.
Distribution and habitat of Nitellopsis obtusa (Characeae) in the Laurentian Great Lakes
Nitellopsis obtusa, a macroalga (Characeae) native to Europe and Asia, was found in U.S. waters of the St. Clair-Detroit River system in 1983, thus extending the range of this taxon into the
