Ecological stoichiometry and the shape of resource-based tradeoffs

Article Abstract:

Fitness tradeoffs are expected when organisms must allocate a limited resource between two or more traits, despite the fact that most resources are made up of multiple elements or components as tradeoff models are traditionally implicitly or explicitly based on a single currency. The model suggested that though the fitness function is fixed, an optical combination of traits vary depending on the stoichiometry of both the traits and the supplied resource.

Behavioral tradeoffs when dispersing across a patchy landscape

Article Abstract:

A stimulation model was used to investigate three questions about behavioral tradeoffs that dispersing animals might face speed of movement against risk of predation, the speed of movement against foraging, and perceptual range against risk of predation. However patch arrangement and search strategy employed by the dispersers had marginal effects on this tradeoff relative to the above parameters.

Recent advances in ecological stoichiometry: Insights for population and community ecology

Article Abstract:

Ecological stoichiometry, the study of the balance of elements in ecological processes, offers a framework for exploring ecological effects of the constraints. Studies show that stoichiometric constraints can affect several properties of populations and community's competitive interactions between different guilds.
