Hybridization facilitates evolutionary rescue
The resilience of populations to rapid environmental degradation is a major concern for biodiversity conservation. When environments deteriorate to lethal levels, species must evolve to adapt to the new conditions to avoid extinction. Here, we test the hypothesis that evolutionary rescue may be enabled by hybridization, because hybridization increases genetic variability. Using experimental evo...
متن کاملHybridization of Evolutionary Algorithms
Iztok Fister,∗ Marjan Mernik,† and Janez Brest‡ Abstract Evolutionary algorithms are good general problem solver but suffer from a lack of domain specific knowledge. However, the problem specific knowledge can be added to evolutionary algorithms by hybridizing. Interestingly, all the elements of the evolutionary algorithms can be hybridized. In this chapter, the hybridization of the three eleme...
متن کاملHow competition affects evolutionary rescue.
Populations facing novel environments can persist by adapting. In nature, the ability to adapt and persist will depend on interactions between coexisting individuals. Here we use an adaptive dynamic model to assess how the potential for evolutionary rescue is affected by intra- and interspecific competition. Intraspecific competition (negative density-dependence) lowers abundance, which decreas...
متن کاملApplication of Embryo Rescue Technique in Juglans regia L. x J. nigra L. Hybridization
Embryo culture were used to produce inter specific walnut hybrid plants between Juglans nigra L. and J. regia L. Developed ovaries were collected from J. rejia female flowers which were pollinated with J. nigra pollen grain by high dusting on a mature tree. In order to isolate embryos, exocarps were aseptically removed. Isolated embryos from ovules at different developmental stages were transfe...
متن کاملEvolutionary rescue beyond the models.
Laboratory model systems and mathematical models have shed considerable light on the fundamental properties and processes of evolutionary rescue. But it remains to determine the extent to which these model-based findings can help biologists predict when evolution will fail or succeed in rescuing natural populations that are facing novel conditions that threaten their persistence. In this articl...
