Megalodon was no cold-blooded killer      (via sciencedaily.com)     Original source 

How the megalodon, a shark that went extinct 3.6 million years ago, stayed warm was a matter of speculation among scientists. Using an analysis of tooth fossils from the megalodon and other sharks of the same period, a study suggests the animal was able to maintain a body temperature well above the temperature of the water in which it lived. The finding could help explain why the megalodon went extinct during the Pliocene Epoch.

Extinct warbler's genome sequenced from museum specimens      (via sciencedaily.com)     Original source 

The Bachman's warbler, a songbird that was last seen in North America nearly 40 years ago, was a distinct species and not a hybrid of its two living sister species, according a new study in which the full genomes of seven museum specimens of the bird were sequenced.

New study reveals global reservoirs are becoming emptier      (via sciencedaily.com)     Original source 

Over the past two decades, global reservoirs have become increasingly empty despite an overall increase in total storage capacity due to the construction of new reservoirs. Researchers used a new approach with satellite data to estimate the storage variations of 7,245 global reservoirs from 1999 to 2018.

Are viruses keeping sea lice at bay in wild salmon?      (via sciencedaily.com)     Original source 

More than 30 previously unknown RNA viruses in sea lice have been identified. Sea lice are parasitic copepods (small crustaceans) found in many fresh and saltwater habitats, and have been implicated in the decline of wild salmon populations. The research sheds greater light on the types of viruses being carried by sea lice, and how the viruses and host are interacting.

Do hummingbirds drink alcohol? More often than you think      (via sciencedaily.com)     Original source 

Animals that eat fruit or sip nectar often ingest alcohol because naturally occurring yeasts turning sugar into ethanol. But how do animals feel about that? A new study details an experiment to determine whether hummingbirds are turned off by alcohol in sugar water. At 1% by volume, no. At 2% by volume, they consume much less. The implication is that hummingbirds have adjusted to small amounts of alcohol likely present in flowers and backyard feeders.

Sinking seamount offers clues to slow motion earthquakes      (via sciencedaily.com)     Original source 

The first ever 3D seismic imaging of a subducting seamount shows a previously unknown sediment trail in Earth's crust off the coast of New Zealand. Scientists think the sediment patches help release tectonic pressure gradually in slow slip earthquakes instead of violent tremors. The findings will help researchers search for similar patterns at other subduction zones like Cascadia in the U.S. Pacific Northwest.

Global analysis on pollinators in cities: Wild bees and butterflies are at particular risk      (via sciencedaily.com)     Original source 

Butterflies are being hit hardest by urban growth. Shrinking habitats and food availability are causing their populations to decline. The same applies to many wild bees that fly early in spring. According to a new study, pollination has not yet been impacted by this because honeybees, for example, can compensate for the reduction of urban pollinators. The study is the first comprehensive analysis of the subject and includes data from 133 studies. The results underline the importance of nature conservation measures in urban areas.

Monarchs' white spots aid migration      (via sciencedaily.com)     Original source 

If you've ever wondered how the monarch butterfly got its spots, University of Georgia researchers may have just found the answer. The new study suggests that the butterflies with more white spots are more successful at reaching their long-distance wintering destination. Although it's not yet clear how the spots aid the species' migration, it's possible that the spots change airflow patterns around their wings.

Engineers 'strike gold' with innovation that recovers heavy metals from biosolids      (via sciencedaily.com)     Original source 

Engineers have developed a cost-effective and environmentally friendly way to remove heavy metals, including copper and zinc, from biosolids. The team's work advances other methods for heavy-metal removal by recycling the acidic liquid waste that is produced during the recovery phase, instead of throwing it away.
