Food Web Topology in High Mountain Lakes
Although diversity and limnology of alpine lake systems are well studied, their food web structure and properties have rarely been addressed. Here, the topological food webs of three high mountain lakes in Central Spain were examined. We first addressed the pelagic networks of the lakes, and then we explored how food web topology changed when benthic biota was included to establish complete tro...

متن کاملTemperature profiles and bathymetry of some high mountain lakes.
The ice cover in high mountain lakes breaks up and disappears in about an hour, in part because it has been divided into fragile vertical spindles, which are individual crystals. Contributing to this process are vertical holes in the ice remaining after particles of dust melt downward as they are warmed by the sun. Temperature profiles of lakes in the Wind River Mountains of Wyoming include tho...
متن کاملPolycyclic Aromatic Hydrocarbons in a Remote High Mountain Lake Food Web in the Central Pyrenees
Brown trouts (Salmo trutta) from four European high mountain lakes (Norway, the Pyrenees,the Alps and the Tatras) were analyzed for metal and organic pollution, histopathologicalabnormalities and biochemical parameters. Fish from all lakes appeared well nourished withconditioning factors close to unity. Their mean age ranged from 4 to 14 years old inGossenköllesee and Vel’ké...
متن کاملFood-web stability signals critical transitions in temperate shallow lakes
A principal aim of ecologists is to identify critical levels of environmental change beyond which ecosystems undergo radical shifts in their functioning. Both food-web theory and alternative stable states theory provide fundamental clues to mechanisms conferring stability to natural systems. Yet, it is unclear how the concept of food-web stability is associated with the resilience of ecosystems...
