We also tested two models that predict slowdowns in the tempo of diversification (density-dependent exponential and density-dependent logistic (DDX and DDL, [ 46]).
This led to a greater coevolution, perhaps leading to the higher density & diversification of both plants and animals in the Tertiary and present.
Faced with new challenges, such as emerging diseases, shortening of orchard longevity, and larger social and environmental demands from consumers, practices such as rootstock diversification, irrigation and high density plantings have become relevant for the Brazilian citrus industry.
For instance, while asymptotic functions may not necessarily reflect density-dependent diversification [ 91– 93], failure to identify diversification slowdowns does not rule out a density-dependent diversification [ 9].
An exponential model of density-dependent diversification fit the scarines best but the 95% credible interval did not exclude the pure birth model (Table 3).
Our phylogenetic analyses lend support to a density-dependent lineage diversification model.
This suggests that our inference of a temperate peak in diversification rates is largely independent from sampling density.
For instance, it has been suggested that abundance (measured as group size or population density) is positively linked to diversification rate in mammals [ 62].
A density-dependent model of declining diversification is the best explanation of cladogenesis in AeglaA.
We present a range of models to explore the intraspecific and interspecific density effects on longevity and, consequently, diversification.
