29 May 2014 Trade-offs are sufficient to drive the evolution of specialization in This best mirrors evolutionary and ecological dynamics of unicellular, Ecosystem services trade-offs can be classified along three axes: spatial scale, temporal scale, and reversibility (Fig. 2). “Spatial scale†refers to whether the effects of the trade-off are felt locally or at a distant location. “Temporal scale†refers to whether the effects take place relatively rapidly or slowly. “Reversibility†expresses the likelihood that the perturbed ES may return to its original state if the perturbation ceases. Trade‐offs in community ecology: linking spatial scales and species coexistence Introduction. In evolutionary biology, the ‘Darwinian demon’ reigns supreme in the world Trade‐Offs and scale. Local‐scale coexistence and trade‐offs. The reductionist paradigm which focuses on controlled Before even jumping into the evolutionary biology material, what is a trade-off? Well, a trade-off is when a choice must be made between multiple things that are either incompatible or an increase in one thing might lead to a decrease in another. A trade-off is a situation where to gain some advantage, you have to pay a price. Big brains in people are a good example. Our brains are certainly nice to have but they are costly in terms of the energy they use up, make childbirth difficult, and are easily damaged. Trade-offs among ecosystem services can generate conflicts in natural resource management, development, and planning. Trade-offs can occur because of inherent constraints of the biological, ecological, and physical system (called “biophysical” hereafter).

Predicting species abundances in a grassland biodiversity experiment: Trade‐offs between model complexity and generality Author Adam Clark discusses the paper in more detail and explores the trade‐off between bias and variance when modelling ecological systems. It is common knowledge that increasing the number of… To examine trade-offs between life-history decisions and immune defense, ecologists need to be able to measure an individual's immunocompetence; that is, it is necessary to be able to quantify how immunocompetence changes as investment in a life-history component changes. Such trade-offs have major implications for the selection of strains, and for the design of growing conditions and harvesting technologies. Understanding trade-offs is critical to maximising the performance of cultivated strains in terms of multiple functions, including growth, lipid concentration, nutrient demands and resistance to enemies. Trade‐offs between functional traits are ubiquitous in nature and can promote species coexistence depending on their shape. Classic theory predicts that convex trade‐offs facilitate coexistence of specialized species with extreme trait values (extreme species) while concave trade‐offs promote species with intermediate trait values (intermediate species).
Trade-offs among ecosystem services can generate conflicts in natural resource management, development, and planning. Trade-offs can occur because of inherent constraints of the biological, ecological, and physical system (called “biophysical” hereafter). Empirically, trade-offs usually are initially identified by comparing species or individuals within species, and testing for a negative relationship between two (or more) traits. A classic example is the trade-off between speed and stamina among species of animals (e.g., A trade-off is when we choose one option in favor of another and the opportunity cost is what is sacrificed in order to get something. Whether we realize it or not, we are constantly evaluating the costs and benefits of each decision we make; therefore, it can also be said that we are performing our own cost-benefit analysis each time we make a choice.
