FEEDBACK LOOP. "Whether or not divergent selection results in ecological speciation depends on the strength of divergent selection relative to gene flow. This balance is dynamic and can itself evolve, generating a feedback loop in which gene flow can impede divergence, and divergent adaptation can impede gene flow." Think about this one. http://www.sciencedirect.com/science/article/pii/S0960982206014138 View in LinkedIn

EXTINCTION. "The concept of extinction through introgressive hybridization is established in conservation biology in the context of anthropogenic species translocations which bring into contact otherwise allopatric species." http://www.sciencedirect.com/science/article/pii/S0960982206014138 View in LinkedIn

NATURAL OUTCOME. "It is likely that incipient speciation and its reversal naturally characterize evolutionary dynamics of ecological speciation and adaptive radiation. Indeed the level of reproductive isolation between species of Darwin's Finches varies between years with and without selection against hybrids. Such alternation between progress and regress in speciation during adaptive radiations may even increase the adaptability of genomes." http://www.sciencedirect.com/science/article/pii/S0960982206014138 View in LinkedIn

IRREVERSIBILITY. "It is likely that in many cases of ecological speciation the selection/gene flow balance tilts through natural processes before speciation becomes irreversible." http://www.sciencedirect.com/science/article/pii/S0960982206014138 View in LinkedIn

DRIVER OF LOSS. "Speciation reversal: the erosion of species differentiation via an increase in introgressive hybridization due to the weakening of previously divergent selection regimes, is thought to be an important, yet poorly understood, driver of biodiversity loss." https://lnkd.in/djvnZZr View in LinkedIn

GENOMIC ISLANDS. "During ecological speciation gene flow between diverging populations is expected to be restricted mainly at loci underpinning traits involved in divergent adaptation and areas of the genome in physical linkage with these loci; so called “genomic islands of divergence”. http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-13-108 View in LinkedIn

BALANCE FACTORS. "Among recently diverged species, the balance between disruptive selection and homogenizing gene flow will determine the extent of genetic differentiation achieved and its genomic distribution." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-13-108 View in LinkedIn

EXTREME EDGE. "This heterogeneous genomic divergence will be at its most extreme during moderate to high gene flow and strong exogenous disruptive selection, predicted to characterize the early stages of sympatric/parapatric speciation scenarios." https://lnkd.in/djvnZZr View in LinkedIn

INCREASING ISLANDS. "As speciation progresses, genomic islands may increase both in number and extent, as inter-specific recombination rates decrease, potentially enhancing reproductive isolation via divergence hitchhiking." Lovely image of speciation. http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-13-108 View in LinkedIn

GENOME HITCHHIKING. "At later stages of ecological speciation, as many loci diverge among incipient species, genome-wide effective gene flow will be reduced even at unlinked loci: divergence hitchhiking being superseded by genome hitchhiking." http://bmcevolbiol.biomedcentral.com/articles/10.1186/1471-2148-13-108 View in LinkedIn
