Reef-building corals provide the structural basis for one of Earth's most spectacular and diverse—but increasingly threatened—ecosystems. Modern Indo-Pacific reefs are dominated by species staghorn coral genus Acropora, but evolutionary ecological factors associated with their diversification rise to dominance unclear. Recent work on radiations has demonstrated importance introgression opportunity in promoting success. Here, we analyze genomes five examine roles Acropora. We found evidence a history marked major event as well recurrent gene flow across species. In addition, that genes topologies mismatching tree evolving faster, which is suggestive role spreading adaptive genetic variation. Demographic analysis showed Acropora lineages profited from climate-driven mass extinctions Plio-Pleistocene, indicating exploited opened new climatic regime favoring could cope rapid sea-level changes. Collectively, reef-building have recorded an shaped climate change, suggesting Acropora—among vulnerable stressors—may be critical understanding how track impending changes Anthropocene.

Urban evolution of invasive species

Frontiers in Ecology and the Environment, Journal Year: 2021, Volume and Issue: 19(3), P. 184 - 191

Urban areas can drive rapid evolution of species and are hotspots for entry establishment invasive species, but it is unclear how urban impacting the process risk invasion by non‐native species. Using a synthesis current research as basis, we contend that enhance invader establishment, spread, ecological impact, which facilitate success under future global change conditions. In addition, highlight opportunity in potentially important unexplored mechanism could accelerate evolution. invaders critical new area reveal novel pathways mechanisms process, improve predictions management around world.

Megaevolutionary dynamics and the timing of evolutionary innovation in reptiles

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: July 3, 2020

The origin of phenotypic diversity among higher clades is one the most fundamental topics in evolutionary biology. However, due to methodological challenges, few studies have assessed rates evolution and disparity across broad scales time understand dynamics behind early new clades. Here, we provide a total-evidence dating approach this problem diapsid reptiles. We find major chronological gaps between periods high (phenotypic molecular) expansion reptile evolution. Importantly, many instances accelerated are detected at body plans, but not concurrent with previously proposed adaptive radiation. Furthermore, strongly heterogenic mark acquisition similarly adapted functional types, snakes marked by highest history.

Community coalescence: an eco-evolutionary perspective

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2020, Volume and Issue: 375(1798), P. 20190252 - 20190252

Community coalescence, the mixing of different communities, is widespread throughout microbial ecology. Coalescence can result in approximately equal contributions from founding communities or dominance one community over another. These outcomes have ramifications for structure and function natural use biotechnology medicine. However, we little understanding when a particular outcome might be expected. Here, integrate existing theory data to speculate on how crucial characteristic communities-the type species interaction that dominates community-might affect coalescence. Given often comparable timescales ecology microevolution, explicitly consider ecological evolutionary dynamics, their interplay, determining coalescence outcomes.
