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 ...
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.
20 Ιαν 2014 · 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., cats versus dogs) and among Olympic athletes (e.g., the best sprinters are ...
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 are thought to arise from inevitable, biophysical limitations that prevent organisms from optimizing multiple traits simultaneously. A leading explanation for biodiversity...
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.
10 Ιουν 2024 · Here, I synthesise evidence of trade-offs in plankton organisms, from bacteria to zooplankton, and show how a slow–fast gradient in life histories emerges. I focus on trade-offs related to the main components of an organism's Darwinian fitness, that is resource acquisition, survival, and propagation.
