   Mar 23, 2020 · While macroevolutionary patterns show trade-offs in species' resource-use traits, we found that positively correlated adaptive trait changes drive within-species responses to resource limitation, altering the expected outcome of competition.

   Nov 14, 2010 · Changes in the population size of a species affect two separate, but related, ecological properties: (i) processes that act in a density-dependent fashion, and (ii) processes that depend on the frequency of interactions that a species has with heterospecifics versus conspecifics.

   Sep 27, 2022 · Tilman's Resource Competition Theory (RCT) proposes that species' minimum resource requirements (R*s) measured in isolation, can predict a priori the outcome of competition amongst species for a limiting resource (R) (Tilman, 1982, Figure 1, part 2).

   Does density-independent resource access predict competition-related traits?

   • By contrast, when average per capita resource access is density-independent, proportional rank should predict competition-related traits. In reality, competition within animal social groups, which experience dynamic, ongoing changes in group size and resources, will rarely be purely density-dependent or density-independent.

   Which rank metric predicts traits when competition is density-independent?

   • We propose that simple ordinal rank best predicts traits when competition is density-dependent, whereas proportional rank best predicts traits when competition is density-independent. We found that for 75% of traits (15/20), one rank metric performed better than the other.

   Does competition reflect a mixture of density-dependence and density-independence?

   • Instead, most competition will reflect a mixture of these two regimes. This point is illustrated in figure 2 for one resource important to males (number of oestrous females); neither density-dependence nor density-independence perfectly describes the relationship between group size and resource availability.

   Do female traits reflect density-independent competitive processes?

   • Thus, only some female traits reflect density-independent competitive processes; other female traits are likely to be shaped by density-dependent competition, or are the result of both density-dependent and density-independent competition, perhaps indicating that females are competing for resources other than food.

   Are female competitive environments shaped by density-independent competition?

   • In partial support of our second prediction, we found that female competitive environments are often shaped by density-independent competition: in over half the female traits in which one of the two rank metrics performed better, proportional rank received stronger support than simple ordinal rank.

   What is resource competition theory?

   • Resource competition theory (RCT ) predicts that a few key resource traits, including the minimum resource level a population requires to maintain positive population growth (R *), determine the outcome of competition over short timescales .

   ship between populations and their resources that causes density dependence by resorting to using more mechanistic consumer–resource models. For instance, Matessi and Gatto (1984) show how resource dynamics and especially con-sumer traits have to be taken into account in order to under-stand density-dependent selection (Fronhofer and Altermatt
