Change and Aging Senescence as an adaptation [PDF]
, 2011 Understanding why we age is a long-lived open problem in evolutionary biology. Aging is prejudicial to the individual and evolutionary forces should prevent it, but many species show signs of senescence as individuals age.

Apparent competition drives community-wide parasitism rates and changes in host abundance across ecosystem boundaries [PDF]
, 2016 Species have strong indirect effects on others, and predicting these effects is a central challenge in ecology. Prey species sharing an enemy (predator or parasitoid) can be linked by apparent competition, but it is unknown whether this process is strong

Principles of parametric estimation in modeling language competition [PDF]
, 2013 It is generally difficult to define reasonable parameters and interpret their values in mathematical models of social phenomena. Rather than directly fitting abstract parameters against empirical data, we should define some concrete parameters to denote ...

Effect of inbreeding and heritability of sperm competition success in the bulb mite Rhizoglyphus robini [PDF]
, 2005 Sperm competition is a potent evolutionary force shaping the reproductive biology of most animal species. Here, we estimated the heritability of sperm competition success in the promiscuous bulb mite Rhizoglyphus robini.

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.

The coevolution of toxin and antitoxin genes drives the dynamics of bacterial addiction complexes and intragenomic conflict [PDF]
, 2012 Bacterial genomes commonly contain ‘addiction’ gene complexes that code for both a toxin and a corresponding antitoxin. As long as both genes are expressed, cells carrying the complex can remain healthy.
