In fact, due to long-term impacts on food webs, Nr inputs are widely considered the most critical pollution problem in marine systems. [8] In both terrestrial and aquatic ecosystems, responses to N enrichment vary; however, a general re-occurring theme is the importance of thresholds (e.g., nitrogen saturation ) in system nutrient retention ...
Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed. For example, a top-down cascade will occur if predators are effective enough in predation to reduce the abundance, or alter the behavior of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate ...
Between 8-18 inches had fallen in lake-effect bands off Lake Ontario, but heavier snows were expected here Saturday. An intense band of snow capable of 2-3 inch-per-hour rates will shift north ...
US and Canadian officials are investigating after a 689-foot ship collided with an underwater object and began taking on water in Lake Superior, the US Coast Guard says.
The first significant lake-effect snowstorm of the season, which buried cities from Michigan to New York under 3-5 feet of snow, will finally begin to wind down on Tuesday after the relentless ...
Siskiwit Lake [1] is the largest lake on Isle Royale in Lake Superior. 4,150 acres (16.8 km 2) in area, [2] the lake has cold, clear water which is relatively low in nutrients. [3] Tributaries include the Little Siskiwit River , and the lake's outlet is the Siskiwit River which flows into Lake Superior.
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
