FRAGMENT FROM NATURE focuses on a wide-ranging and interesting article by professor Reto Burri, a German ecologist, about evolution that covers the links between natural selection, demography and genomics, with an emphasis on birds; this covers a sizable chunk of the heart of evolution. https://lnkd.in/d6894Jh View in LinkedIn

FITNESS IS THE CORE. “Patterns of survival and reproduction determine fitness and so it should come as no surprise that there is a rich body of theory linking demography with evolution.” https://lnkd.in/dM7i949 View in LinkedIn

ADAPTATION, TWO WAYS. “Recent eco-evolutionary research focuses on how rapid adaptation influences ecology, and vice versa.” https://lnkd.in/dv4gE6X View in LinkedIn

NON-ADAPTIVE. “Evolution by non-adaptive forces also occurs quickly, with ecological consequences.” https://lnkd.in/dv4gE6X View in LinkedIn

SELECTION IS CORE. “Selection has a deep impact on the distribution of genetic diversity and population differentiation along the genome (the genomic landscapes of diversity and differentiation), reducing diversity and elevating differentiation not only at the sites it targets, but also at linked neutral sites.” https://lnkd.in/dWhdAqA View in LinkedIn

ANOTHER ROUTE. “The genomic landscapes of diversity and differentiation are usually highly heterogeneous, it has also led to the increasing realization that this heterogeneity may evolve under processes other than adaptation or speciation.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

PURIFYING SELECTION. “Instead of being an effect of selective sweeps or barriers to gene flow, accentuated differentiation can evolve by any process reducing genetic diversity locally within the genome, including purifying selection at linked sites (background selection).” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

EVOLUTIONARY SPANDREL. “In genomic regions where recombination is infrequent, accentuated differentiation can evolve as a by-product of diversity reductions unrelated to adaptation or speciation.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn

ACTIVE SPANDRELS. “In such genomic regions, linkage extends over physically larger genome stretches, and selection affects a particularly high number of linked neutral sites.” http://onlinelibrary.wiley.com/doi/10.1111/mec.14167/full View in LinkedIn
