Atmospheric dust gives plants nutrients through their leaves, study finds

By integrating field observations with dust-deposition estimates and soil nutrient data from different regions, investigators found that during dust events, daily nutrient inputs via foliar uptake can match or exceed soil-derived inputs.

Tiny African fish caught climbing to the top of a 50-foot waterfall

For over half a century, people in Central Africa have told tales of the fish seen climbing waterfalls, but these claims have never been officially confirmed. Now, these fish have finally been caught on camera, studied more closely, and described in a study published in Scientific Reports.

Parasites defy biodiversity rules, thriving far from the equator

Parasite infections in [tropical regions] often lead to higher mortality, which makes it harder for parasites to persist. In cooler temperate waters, hosts can tolerate infections better, giving parasites a chance to survive, reproduce and complete their complex lifecycles.

Massive insect body size 300 million years ago may not have been due to high atmospheric oxygen

[The study] found that the space occupied by tracheoles in the flight muscle is typically only 1% or less in most species[.] This suggests that the flight muscles of insects are not constrained by atmospheric oxygen levels as they could easily add tracheoles in the muscle, since they take up so little space.

Highly and casually active citizen scientists contribute equally valuable data

The tendency for people to observe in a particular type of area results in lopsided (biased) data that scientists have to account for when conducting their analyses. […] This study shows that the bias toward natural areas perpetuated by super-users is partly balanced by those of casual users.

Camera captures first video of a red fox attacking a wolf pup

The footage clearly shows the fox sniffing around the den cavity, then venturing inside and dragging a live pup back out. The young wolf manages to escape back into the den, but the fox enters a second time and captures it. The sounds of its distress are clearly audible.

The Black Death's counterintuitive effect: As human numbers fell, so did plant diversity

[Farmlands] were typically separated by woods, rough grazing lands and uncultivated plots, often enclosed by hedgerows or trees. [This patchy landscape resulted in high biodiversity.] The Black Death disrupted this by reducing human disturbance.
