Simulated data for: Patch biogeography under intermittent barriers: Macroevolutionary consequences of microevolutionary processes

The processes that generate biodiversity start on a microevolutionary
scale, where each individual’s history can impact the species’ history.
This manuscript presents a theoretical study that examines the
macroevolutionary patterns that emerge from the microevolutionary dynamics
of populations inhabiting two patches. The model is neutral, meaning that
neither survival nor reproduction depends on a fixed genotype, yet
individuals must have minimal genetic similarity to reproduce. We used
historical sea level oscillation over the past 800 thousand years to
hypothesize periods when individuals could migrate from one patch to
another. In our study, we keep track of each speciation and extinction
event, build the complete and extant phylogenies, and characterize the
macroevolutionary patterns regarding phylogeny balance, acceleration of
speciation, and crown age. We also evaluate ecological patterns: richness,
beta diversity, and species distribution symmetry. The balance of the
complete phylogeny can be a sign of the speciation mode, contrasting
speciation induced by migration and isolation (vicariance). The
acceleration of the speciation process is also affected by the
geographical barriers and the duration of the isolation period, with high
isolation times leading to accelerated speciation. We report the
correlation between ecological and macroevolutionary patterns and show
that it decreases with the time spent in isolation. We discuss, in light
of our results, the challenge of integrating present-time community
ecology with macroevolutionary patterns.
