The redpoll finch saga: How two bird species just became one

[The] hoary redpoll finch, a small, plump bird commonly found in the Arctic, will be reclassified as the same species as the common redpoll finch, a smaller bird found in similar habitats. This announcement came as a direct result of a CU Boulder-led study which found that, despite their different looks, very few genetic differences exist between the two types of birds.

Luonnontieteellisten museoiden digitoidut näytteet vahvistivat ikivanhan tutkimushypoteesin | Helsingin yliopisto

Klassinen hypoteesi esittää, että suojaväritykseen luottavat saaliseläimet ovat ulkoasultaan vaihtelevampia kuin varoitussignaaleihin luottavat saaliseläimet. […] Tutkijat löysivät hypoteesille vahvistuksen käyttämällä luonnontieteellisten museoiden digitaalisia kokoelmia ja mittaamalla tuhansista kuvista perhoslajien sisäistä värien ja kuvioiden muuntelua.

COVID-19 virus is evolving rapidly in white-tailed deer, new research finds

The combined findings suggest that the white-tailed deer species is a reservoir for SARS-CoV-2 that enables continuing mutation, and that the virus's circulation in deer could lead to its spread to other wildlife and livestock.

Hookworms successfully prevent type 2 diabetes in human trial

“The JCU trial provides sufficient proof of concept that infection with live hookworms is safe and appears to have some sort of beneficial effects on people’s metabolic health, which will hopefully be confirmed by future clinical trials designed to confirm efficacy and explore how hookworms influence metabolism[.]”

Seasonal specialization in butterflies determines responses to a changing climate

"The small white butterfly is better than the green-veined white butterfly at reproducing over the summer but has poorer winter survival. It appears to be a 'summer specialist' and the green-veined white butterfly a 'winter specialist.'"
