Trade off in biology

Such species are important tests of the model, as a slow breeding strategy suggests a particularly potent trade-off between offspring investment and reproductive rate. Understanding how individuals negotiate this trade-off can provide important insights into the evolution of reproductive biology and behavior. There is an adaptation in some humans that makes them very resistant to malaria. The trade off is that they have sickle cell anemia which can cause blood clots to form internally.

Such a situation can be caused by a number of physical and biological mechanisms. One type of mechanism is described by the so-called ‘Y-model’, which states that for a given amount of resource (e.g., energy, space, time), it is impossible to increase two traits at once. In biology, a trade-off exists when one trait cannot increase without a decrease in another (or vice versa). In evolution, organisms cannot invest in everything, so they either invest in one trait or another and in evolutionary term, we call it an evolutionary trade off. A trade-off (or tradeoff) is a situational decision that involves diminishing or losing one quality, quantity or property of a set or design in return for gains in other aspects. In simple terms, a tradeoff is where one thing increases and another must decrease. 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. In biology, we talk a lot about trade-offs. This usually means that when something gets better in one aspect of an organism’s biology, something else suffers. Consider a tree species in a forest and its ability to survive a forest fire. In biology, a trade-off exists when one trait cannot increase without a decrease in another (or vice versa). Such a situation can be caused by a number of physical and biological mechanisms. One type of mechanism is described by the so-called ‘Y-model’,

Trade‐offs in species performances of different ecological functions is one of the most common explanations for coexistence in communities. Despite the potential for species coexistence occurring at local or regional spatial scales, trade‐offs are typically approached at a single scale. Stearns founded and has served as president of both the European Society for Evolutionary Biology and the Tropical Biology Association, was founding editor of the Journal of Evolutionary Biology - animals can alter behavior in a way that removes constraints - like become nocturnal to avoid predation. - trade-offs may only appear at extremes of distribution. - grade shifts can changes means - cause diffs in trade-offs at various phylog. levels - also can reset basic rules of trade-offs and constraints.
