Host–symbiont specificity determined by microbe–microbe competition in an insect gut
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance How are specific host-symbiont mutualisms stabilized without vertical transmission? This is one of the fundamental questions in evolutionary biology.

A systematic review of context bias in invasion biology.
PLoS ONE, 2017 The language that scientists use to frame biological invasions may reveal inherent bias-including how data are interpreted. A frequent critique of invasion biology is the use of value-laden language that may indicate context bias.

Eukaryotic Adaptation to Years-Long Starvation Resembles that of Bacteria
iScience, 2019 Summary: The Growth Advantage in Stationary Phase (GASP) phenomenon, described in bacteria, reflects the genetic adaptation of bacteria to stress, including starvation, for a long time.

New Conditional Symmetries and Exact Solutions of the Diffusive Two-Component Lotka–Volterra System
Mathematics, 2021 The diffusive Lotka–Volterra system arising in an enormous number of mathematical models in biology, physics, ecology, chemistry and society is under study. New Q-conditional (nonclassical) symmetries are derived and applied to search for exact solutions

Soil microbes alter plant fitness under competition and drought
Journal of Evolutionary Biology, 2019 Plants exist across varying biotic and abiotic environments, including variation in the composition of soil microbial communities. The ecological effects of soil microbes on plant communities are well known, whereas less is known about their importance ...

Kin Selection in the RNA World
Life, 2017 Various steps in the RNA world required cooperation. Why did life’s first inhabitants, from polymerases to synthetases, cooperate? We develop kin selection models of the RNA world to answer these questions.

Climate cooling and clade competition likely drove the decline of lamniform sharks
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance Many lineages increase in diversity through time, and some of them eventually decline and get replaced. The causes of such diversity decline remain elusive and are especially difficult to understand over a long-time scale and global ...

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...
