Catherine Collins walking with us through the tāhuhu kōrero in DNA.

#GSA2025 #AotearoaGSA2025

Amazing talks in the Ecological and Evolutionary Genetics, and the Human Genetics concurrent sessions today.

Emma Carroll, Isabelly de Lima, Graham McCulloh, Amara Shaukat, Kathleen McLay, & some excellent lightning talks!

Do freshwater insect assemblages in exotic plantations resemble those from native forest? Evidence from environmental DNA Widespread deforestation has impacted biodiversity patterns globally, but the potential for forest plantations to restore biodiversity remains unclear. Here we used environmental DNA (eDNA) analysis ...

Science magazine front cover. Picture of a walnut in its opened shell. The text reads "All about timing. Mating type evolution in walnuts and pecans"

graphical abstract: "In Juglans (top left) and Carya, two morphs show complementary temporal separation between male and female flowering (heterodichogamy). Mating types are controlled by two nonhomologous single-locus mechanisms that arose in the common ancestor of each genus, respectively. (Bottom left) Simplified schematic of a putative functional regulatory element at the Juglans locus. (Bottom right) Strong genotypic correlations across the Carya locus indicate a lack of recombination between two colinear haplotypes with similar gene content."

Congrats to @jeffgroh.bsky.social et al on publication of "Ancient structural variants control sex-specific flowering time morphs in walnuts and hickories"

is this the global test across wolves/loci?

An insect with a reddish-brown abdomen that ends in pinchers, large translucent wings with gold elytra, and a reddish brown head. It is standing at the end of a leaf.

Good morning! This is your periodic reminder that earwigs have wings.

Wow! The complex genomic and epigenetic variation that builds the tasty diversity of Brassica oleracea (the single species that forms broccoli, cauliflower, kale, cabbage, Brussels sprouts)

Stoneflies change colour in response to deforestation, suggesting humans can alter evolution – new research A new study shows that rapid loss of forests has prompted a colour change in stoneflies, caused by a genetic mutation. This means human change to the environment can drive evolution.

I had the opportunity to contribute to a study on mimicry! Shout out to Jon Waters & Graham McCulloch for inviting me to join the team!
