Moths are more efficient pollinators than bees, shows new research
[The] researchers found that 83% of insect visits to bramble flowers were made during the day. While the moths made fewer visits during the shorter summer nights, notching up only 15% of the visits, they were able to pollinate the flowers more quickly.

Study shows bird feeding helps small birds fight infection
When the birds were exposed to a simulated infection, all the birds had essentially the same temperature during a fever. Instead of conserving energy to survive the winter, the birds without access to extra food were forced to use more energy in order to raise their body temperature high enough to battle infection.

Tutkimus | Valosaaste vaikuttaa haitallisesti perhosten talvehtimiseen
Valosaaste saa yksilöt läpikäymään muodonvaihdoksen aikuiseksi perhoseksi liian myöhään syksyllä sen sijaan, että ne kehittyisivät talvenkestäviksi koteloiksi. […] Tutkimuksen mukaan kaupunki- ja maaseutupopulaatioiden perhoset reagoivat valosaasteeseen samalla tavalla.
