Four lichen species new to science discovered in Kenyan cloud forests

Four lichen species new to science discovered in Kenyan cloud forests
Some of the newly described lichen species from the Micarea genus may be unique to the biodiversity hotspot that is the Taita Hills in Kenya. The area may contain even more lichen species yet to be discovered.
Researchers from the University of Helsinki’s Finnish Museum of Natural History Luomus and the National Museums of Kenya have discovered four lichen species new to science in the rainforests of the Taita Hills in southeast Kenya.
Micarea pumila, M. stellaris, M. taitensis and M. versicolor are small lichens that grow on the bark of trees and on decaying wood. The species were described based on morphological features and DNA-characters. ....

New study reveals habitat that could increase jaguar numbers

E-Mail
Tucson, Ariz. (March 16, 2021) - This week, a new, peer-reviewed scientific study finds that there is far more potential jaguar habitat in the U.S. than was previously thought. Scientists identified an area of more than 20 million acres that could support jaguars in the U.S., 27 times the size of designated critical habitat.
The results, published in the journal
Oryx, are based on a review of 12 habitat models for jaguars within Arizona and New Mexico, conclusively identifying areas suitable for the recovery of these wild cats. Based on the expanded habitat area, the authors conclude that findings uncover new opportunities for jaguar conservation in North America that could address threats from habitat loss, climate change, and border infrastructure. ....

Protecting the ocean delivers a comprehensive solution for climate, fishing and biodiversity

London, UK (17 March 2021) A new study published in the prestigious peer-reviewed scientific journal
Nature today offers a combined solution to several of humanity s most pressing challenges. It is the most comprehensive assessment to date of where strict ocean protection can contribute to a more abundant supply of healthy seafood and provide a cheap, natural solution to address climate change in addition to protecting embattled species and habitats.
An international team of 26 authors identified
specific areas that, if protected, would safeguard over 80% of the habitats for endangered marine species, and increase fishing catches by more than eight million metric tons. The study is also the first to quantify the potential release of carbon dioxide into the ocean from trawling, a widespread fishing practice and finds that ....

Artificial Light Affects Plant Pollination Even During Daytime

Artificial Light Affects Plant Pollination Even During Daytime
Streetlights alter the number of flower visits by insects not just at night, but also during the daytime. Artificial light at night thus indirectly affects the entire plant-pollinator community, with unknown consequences for functioning of the ecosystem, as researchers from the University of Zurich and Agroscope have proven for the first time.

The use of artificial light at night around the world has increased enormously in recent years, causing adverse effects on the survival and reproduction of nocturnal organisms. Artificial light at night interferes with vital ecological processes such as the nighttime pollination of plants by nocturnal insects, which could have consequences for agricultural crop yields and reproduction of wild plants. ....

Washington, DC Algae colonizing dead coral are upending scientists ability to accurately assess the health of a coral reef community, according to new work from a team of marine science experts led by Carnegie s Manoela Romanó de Orte and Ken Caldeira. Their findings are published in
Limnology and Oceanography.
Corals are marine invertebrates that build tiny exoskeletons, which accumulate to form giant coral reefs. Widely appreciated for their beauty, these reefs are havens for biodiversity and crucial for the economies of many coastal communities. But they are endangered by ocean warming, seawater acidification, extreme storms, pollution, and overfishing. ....
