Unifying evolutionary and network dynamics [PDF]
Physical Review E, 2007 Many important real-world networks manifest "small-world" properties such as scale-free degree distributions, small diameters, and clustering. The most common model of growth for these networks is "preferential attachment", where nodes acquire new links with probability proportional to the number of links they already have.

The evolution of non-reproductive workers in insect colonies with haplodiploid genetics
eLife, 2015 Eusociality is a distinct form of biological organization. A key characteristic of advanced eusociality is the presence of non-reproductive workers. Why evolution should produce organisms that sacrifice their own reproductive potential in order to aid ...

Why Do Herbivorous Mites Suppress Plant Defenses?
Frontiers in Plant Science, 2018 Plants have evolved numerous defensive traits that enable them to resist herbivores. In turn, this resistance has selected for herbivores that can cope with defenses by either avoiding, resisting or suppressing them. Several species of herbivorous mites,

Diversity in evolutionary dynamics
Journal of the Royal Society InterfaceAbstract We consider the dynamics imposed by natural selection on the populations of two competing, sexually reproducing, haploid species. In this setting, the fitness of any genotype varies over time due to the changing population mix of the competing species; crucially, unlike other approaches to ensuring time-varying fitnesses, in ...

Evolutionary dynamics of group formation
PLOS ONE, 2017 We introduce a model, based on the Evolutionary Game Theory, for studying the dynamics of group formation. The latter constitutes a relevant phenomenon observed in different animal species, whose individuals tend to cluster together forming groups of different size.

Polymorphism in the symmetries of gastric pouch arrangements in the sea anemone D. lineata
Zoological Letters, 2021 Symmetry in the arrangement of body parts is a distinctive phylogenetic feature of animals. Cnidarians show both bilateral and radial symmetries in their internal organs, such as gastric pouches and muscles.

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Tetranychus evansi spider mite populations suppress tomato defenses to varying degrees
Ecology and Evolution, 2020 Plant defense suppression is an offensive strategy of herbivores, in which they manipulate plant physiological processes to increase their performance. Paradoxically, defense suppression does not always benefit the defense‐suppressing herbivores, because

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
