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 ...
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 ...
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.
18 Μαΐ 2024 · Trade-offs play a key role in controlling bacterial growth and shaping microbial phenotypes, which further drives the emergence of ecologically relevant phenomena including co-existence ...
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.
Trade-offs between phage resistance and other key traits in bacteria have been studied for nearly a century and occur when bacterial evolution results in phage resistance at the cost of another fi tness-generating trait.
1 Ιαν 2022 · Trade-offs and constraints are inherent to life, and studies of these phenomena play a central role in both organismal and evolutionary biology. Trade-offs can be defined, categorized, and studied in at least six, not mutually exclusive, ways.
