    Genomic studies of Heliconius butterflies provide evidence that Heliconius elevatus is a hybrid species, and that its speciation was driven by introgression of traits from Heliconius melpomene into the other parent, an ancestor of Heliconius pardalinus.

    Analysis of two-million-year-old ancient environmental DNA from the Kap København Formation in North Greenland shows there was an open boreal forest with diverse plant and animal species, of which several taxa have not previously been detected at the site, representing an ecosystem that has no present-day analogue.

    A whole-genome alignment of 240 phylogenetically diverse species of eutherian mammal—including 131 previously uncharacterized species—from the Zoonomia Project provides data that support biological discovery, medical research and conservation.

    The predicted increase in frequency of droughts and rising temperatures in Europe will lead core populations of a temperate plant to an evolutionary dead-end unless they acquire genetic alleles that are present only in extreme edge Mediterranean, Scandinavian, or Siberian populations.

    Analysis of three wild-caught bumblebee species shows that family lineage survival and persistence is significantly increased between successive colony cycle stages with the proportion of high-value foraging habitat near the natal colony.

    Genomic and molecular analyses of Clunio marinus timing strains suggest that modulation of alternative splicing of Ca2+/calmodulin-dependent kinase II represents a mechanism for evolutionary adaptation of circadian timing.

    Traits responsible for recent niche divergence between sympatric threespine stickleback species are subjected to forward genetic analysis; additive variation at several loci across the genome accounts for most of the genetic basis of ecological divergence, with a further role for epistatic interactions that disadvantage hybrids.

    The appearance of new ecological niches propels the evolution of species, but the converse can also occur. A study shows that changing lake habitats have caused extinctions and reduced the genetic differences between species. See Article p.357
