Pollinators’ 10 favourite Nordic plants

“In this context, we've examined which plants wild bees and hoverflies prefer in semi-natural meadows and roadsides in Trondheim. It was clear from our recordings that pollinators have different preferences,” says Line Johansen.

Frog ‘saunas’ help endangered frogs survive the devastating impacts of a deadly fungal disease

The research team found artificial 'hotspot' shelters built from readily available materials, such as bricks and PVC greenhouses, can allow frogs to quickly 'bake off' infections with the chytrid fungus. When frogs shifted to hotspot shelters, chytrid infections were reduced significantly.

Starlings found to expend 25% less energy in follower position compared to flying solo

A multidisciplinary, multi-institutional team of researchers in the U.S. has found that starlings that fly in a follower position expend 25% less energy than when they fly solo. […] They also found that the birds that were the most naturally energy-efficient tended to adopt the leader role more readily and easily.

Biologists discover caterpillars are able to sense electrostatic fields generated by predators

[The researchers tested specimens of cinnabar moth, the scarce vapourer moth and the European peacock butterfly] for the ability to sense and react to an artificially generated electrostatic field that matched the output of that generated by a wasp. [All] three species responded very clearly to an electrostatic charge—some flailed their bodies, others coiled in a defensive posture.

Kimalaiset rakentavat legopalikoilla tiedettä ja tunnistavat tiimityön arvon

”Tulokset viittaavat siihen, että kimalaisilla on kyky tunnistaa ja reagoida kumppaninsa läsnäoloon ja liikkeisiin, mikä on hämmästyttävä osoitus niiden sosiaalisesta älykkyydestä”, tutkimusta johtanut eläinekologian dosentti Olli Loukola kertoo.

Researchers determine large numbers of wild mountain goats are killed every year by avalanches

The research team found that death by avalanche was common for the goats—in one region, it was responsible for 65% of deaths. They found that overall, approximately 8% of all wild mountain goat deaths in Alaska were due to avalanches—a percentage they describe as significant.
