Outstanding intraindividual genetic diversity in fissiparous planarians (Dugesia, Platyhelminthes) with facultative sex.

, 2019
Predicted genetic consequences of asexuality include high intraindividual genetic diversity (i.e., the Meselson effect) and accumulation of deleterious mutations (i.e., Muller’s Ratchet), among others.

Red Queen Coevolution on Fitness Landscapes

, 2013
Species do not merely evolve, they also coevolve with other organisms. Coevolution is a major force driving interacting species to continuously evolve ex- ploring their fitness landscapes. Coevolution involves the coupling of species fit- ness landscapes,

Population Genomics Informs Conservation Strategies for Critically Endangered Kokia Species in Hawaiʻi

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Once a common feature of the xeric‐mesic habitats of the Hawaiian Islands, trees from the genus Kokia have undergone severe human‐driven population reductions, with island‐specific pressures resulting in different outcomes for each single island endemic species.

A Method for the Combination of Stochastic Time Varying Load Effects [PDF]

, 1983
The problem of evaluating the probability that a structure becomes unsafe under a combination of loads, over a given time period, is addressed. The loads and load effects are modeled as either pulse (static problem) processes with random occurrence ...

Self‐compatibility in Solanum malmeanum (Solanaceae): Evolutionary and breeding impacts for a novel source of genetic variation in diploid potatoes

TAXON, Volume 75, Issue 2, April 2026.
Abstract Solanum malmeanum, a wild relative of the potato (S. tuberosum), is native to Argentina, Brazil, Paraguay and Uruguay. This wild potato species belongs to the tertiary gene pool (2x = 2n = 24, 1EBN – Endosperm Balance Number) and possesses valuable traits for potato breeding. Understanding its reproductive mechanisms is crucial for effectively
