Persistence of net heterotrophy in lakes during nutrient addition and food web manipulations
TLDR
Estimating in situ NEP using three independent approaches over a 4‐7 yr period in a series of small lakes in which food webs were manipulated and nutrient loadings were experimentally varied found community R is significantly subsidized by allochthonous sources of organic matter in these lakes. Expand
Prey selection naticid gastropods; experimental tests and application to the fossil record
TLDR
Application of the model to several Miocene and Pliocene assemblages studied by Thomas (1976) corroborates the feasibility and utility of this approach in examining the evolutionary record of naticid predation, which extends from the Late Mesozoic. Expand
Regulation of Lake Primary Productivity by Food Web Structure.
TLDR
Food web effects and abiotic factors were equally potent regulators of primary production in these experiments, illustrating the effects of climatic factors and the natural dynamics of unmanipulated food web interactions. Expand
ECOSYSTEM SUBSIDIES: TERRESTRIAL SUPPORT OF AQUATIC FOOD WEBS FROM 13C ADDITION TO CONTRASTING LAKES
Whole-lake additions of dissolved inorganic C-13 were used to measure allochthony (the terrestrial contribution of organic carbon to aquatic consumers) in two unproductive lakes (Paul and Peter LakesExpand
Early Warnings of Regime Shifts: A Whole-Ecosystem Experiment
TLDR
High-frequency monitoring of manipulated and reference lakes enabled early detection of subsequent catastrophic regime shift in an aquatic food web, corroborating theory for leading indicators of ecological regime shifts. Expand
Whole-lake carbon-13 additions reveal terrestrial support of aquatic food webs
TLDR
It is shown, by the experimental manipulation of dissolved inorganic 13C in two lakes, that internal primary production is insufficient to support the food webs of these ecosystems, and there is significant subsidy ofThese ecosystems by organic carbon produced outside their boundaries. Expand
Cultivation/depensation effects on juvenile survival and recruitment: implications for the theory of fishing
TLDR
Risk of depensatory effects should be a major target of recruitment research, and management policies should aim for considerably higher spawning abundances than has previously been assumed necessary based on recruitment data collected during adult stock declines associated with fishery development.
