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 ...
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 ...
19 Φεβ 2015 · Here we present a mechanistic theory, supported by data, on the geometry of two trade-offs among microbes: one is a feeding trade-off, one is a growth trade-off.
Trade-offs are the linkages between traits that constrain the simultaneous evolution of two or more traits. The chapter opens with examples of well-documented trade-offs, then distinguishes between physiological trade-offs—energy allocations between two or more functions competing for the same resources within a single individual—and ...
Generalize the model to represent genetic variation with several genes with pleiotropic effects mediating the trade-off between reproduction and survival. The genes obey Mendel's rules. Keep the physiological allocation model, and let the genetics influence the allocation decisions.
13 Νοε 2017 · There are three fundamental trade-offs in life history theory: current versus future reproduction, quantity versus quality of offspring, and mating versus parenting effort (Kaplan and Gangestad 2005; Del Giudice et al. 2015).
