This section will discuss some of the major trade offs associated with various life history traits and strategies and how these trade offs produce sets of traits that are commonly found together. As outlined in the previous section, a fundamental life history trait is the number of offspring produced per mating.

- 5.5: Principle of Allocation and Evolutionary Trade-offs
20 Ιαν 2014 · What is a trade-off? In engineering and economics, trade-offs are familiar enough (e.g., money spent on rent is not available to buy food). 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.
14 Δεκ 2021 · Trade-offs have a key role in maintaining the genetic diversity of species. To illustrate this, we present some examples of trade-offs for pea aphids (Acyrthosiphon pisum). We use pea aphids not because we think they are an exceptional species, but instead because they are unexceptional; other species are likely to show similarly diverse trade ...
15 Αυγ 2023 · The principle of allocation leads to trade-offs, which are the relationships between the benefits of resource investment decisions in one context compared to the costs of those decisions in another context. You are already familiar with the principle of allocation through the concept of time.
19 Φεβ 2015 · Trade-offs between life-history traits are seen as a key part of the processes that maintain the rich biodiversity observed in microbes 1, plants 2, insects 3 and rain forests 4.
In evolutionary biology, an evolutionary tradeoff is a situation in which evolution cannot advance one part of a biological system without distressing another part of it. In this context, tradeoffs refer to the process through which a trait increases in fitness at the expense of decreased fitness in another trait.
In anemone fish, the nonapeptides arginine, vasotocin, and isotocin mediate a trade-off in parental care behaviors on a timescale of tens of minutes (DeAngelis et al. 2020). Physiological responses that mediate acute trade-offs can also occur within seconds to minutes to hours.
