Panama Canal expansion rewrites history of world's most ecologically diverse bats      (via sciencedaily.com)     Original source 

In a new study, paleontologists describe the oldest-known leaf-nosed bat fossils, which were found along the banks of the Panama Canal. They're also the oldest bat fossils from Central America, preserved 20-million years ago when Panama and the rest of North America were separated from southern landmass by a seaway at least 120 miles wide.

Bat 'nightclubs' may be the key to solving the next pandemic      (via sciencedaily.com)     Original source 

Researchers are studying how bats can carry deadly viruses, but not develop symptoms. They found that what happens during swarming behavior -- like social gatherings for bats -- may hold the key to understanding their viral tolerance and translate to human health in fighting off diseases like Ebola and COVID-19.

The role of jellies as a food source in the Arctic winter      (via sciencedaily.com)     Original source 

The Arctic is changing rapidly due to climate change. It is not only affected by increasing surface temperatures, but also by warm water from the Atlantic, which is flowing in more and more -- changing the structures and functions of the ecosystem as it also leads to species from warmer regions, such as sea jellies (also known as jellyfish) arriving in the Arctic. Using DNA metabarcoding, researchers have now been able to demonstrate that these jellyfish serve as food for amphipods on Svalbard during the polar night and thus play a greater role in Arctic food webs than previously assumed.

Tawny owl's pale grey color linked to vital functions ensuring survival in extreme conditions      (via sciencedaily.com)     Original source 

A recent genetic discovery has revealed that the pale grey plumage of the tawny owl is linked to crucial functions that aid the bird's survival in cold environments. As global temperatures rise, dark brown plumage is likely to become more common in tawny owls living in colder areas.

Australia's most at-risk bird species share some common traits      (via sciencedaily.com)     Original source 

Australian birds that live on islands are among the species most at risk of extinction, a first-of-its-kind study has shown. Australia has over 750 native bird species. But many of them are facing an uncertain future.

Joro spiders well-poised to populate cities      (via sciencedaily.com)     Original source 

The Joro spider was first spotted stateside around 2013 and has since been spotted across Georgia and the Southeast. New research has found more clues as to why the spider has been so successful in its spread. The study found the invasive orb-weaving spider is surprisingly tolerant of the vibrations and noise common in urban landscapes. In this new study, researchers examined how Joro spiders can live next to busy roads, which are notably stressful environments for many animals.

3D printed nanocellulose upscaled for green architectural applications      (via sciencedaily.com)     Original source 

For the first time, a hydrogel material made of nanocellulose and algae has been tested as an alternative, greener architectural material. The study shows how the abundant sustainable material can be 3D printed into a wide array of architectural components, using much less energy than conventional construction methods.

Apex predators not a quick fix for restoring ecosystems      (via sciencedaily.com)     Original source 

An experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return -- at least, not for a very long time. The study challenges the commonly held belief that the reintroduction of wolves to Yellowstone National Park restored an ecosystem degraded by their absence.

Number of shark bites consistent with recent trends, with small spike in fatalities      (via sciencedaily.com)     Original source 

There was an increase in the number of unprovoked shark attacks worldwide and an uptick in fatalities in 2023 compared to the previous year. A scientific database of global shark attacks, confirmed 69 unprovoked bites in 2023. Although this is higher than the most recent five-year average of 63 attacks, the data remain consistent with long-term trends.
