Bouldering in south-central Madagascar: A new 'rock-climbing' gecko species of the genus Paroedura      (via sciencedaily.com)     Original source 

A new Paroedura gecko species was reported at two small forest sites, Anja Reserve and Tsaranoro Valley forest, in the south-central plateau of Madagascar. Thanks to the recently collected samples, it was described and named after its preferred habitat, the boulders surrounded by the last remaining forests at these sites. Its conservation status was evaluated as Critically Endangered given its tiny distributional range.

Mummified feces reveals pre-Columbian cultures of the Caribbean consumed a diversity of plants      (via sciencedaily.com)     Original source 

DNA analysis of mummified feces reveals two pre-Columbian Caribbean cultures ate a wide variety of plants, like maize, sweet potato, and peanuts -- and tobacco and cotton traces were detected too, according to a new study.

Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats      (via sciencedaily.com)     Original source 

Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.

Killing remains a threat to Bornean orangutans      (via sciencedaily.com)     Original source 

New research has found despite considerable conservation efforts, the illegal killing of critically endangered orangutans on Borneo may be an ongoing threat to the species.

Paleoclimatologists use ancient sediment to explore future climate in Africa      (via sciencedaily.com)     Original source 

With global warming apparently here to stay, a team of paleoclimatologists are studying an ancient source to determine future rainfall and drought patterns: fossilized plants that lived on Earth millions of years ago.

Plate tectonic surprise: Geologist unexpectedly finds remnants of a lost mega-plate      (via sciencedaily.com)     Original source 

Geologists have reconstructed a massive and previously unknown tectonic plate that was once one-quarter the size of the Pacific Ocean. The team had predicted its existence over 10 years ago based on fragments of old tectonic plates found deep in the Earth’s mantle. To the lead researchers surprise, she found that oceanic remnants on northern Borneo must have belonged to the long-suspected plate, which scientists have named Pontus. She has now reconstructed the entire plate in its full glory.

Ancient Maya reservoirs offer lessons for today's water crises      (via sciencedaily.com)     Original source 

Ancient Maya reservoirs, which used aquatic plants to filter and clean the water, 'can serve as archetypes for natural, sustainable water systems to address future water needs.' The Maya built and maintained reservoirs that were in use for more than 1,000 years. These reservoirs provided potable water for thousands to tens of thousands of people in cities during the annual, five-month dry season and in periods of prolonged drought.

Ginger pigment molecules found in fossil frogs      (via sciencedaily.com) 

Palaeontologists discover molecular evidence of phaeomelanin, the pigment that produces ginger coloration. Phaeomelanin is now toxic to animals – this discovery may be first step in understand its evolution.

Oldest fossil human footprints in North America confirmed      (via sciencedaily.com)     Original source 

New research reaffirms that human footprints found in White Sands National Park, NM, date to the Last Glacial Maximum, placing humans in North America thousands of years earlier than once thought.  In September 2021, scientists announced that ancient human footprints discovered in White Sands National Park were between 21,000 and 23,000 years old. This discovery pushed the known date of human presence in North America back by thousands of years and implied that early inhabitants and megafauna co-existed for several millennia before the terminal Pleistocene extinction event. In a follow-up study, researchers used two new independent approaches to date the footprints, both of which resulted in the same age range as the original estimate.

Fear of humans pervades the South African savanna      (via sciencedaily.com)     Original source 

Mammals living in South Africa's Greater Kruger National Park, home to one of the world's largest remaining lion populations, are far more afraid of hearing human voices than lion vocalizations or hunting sounds such as dogs barking or gunshots.

Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought      (via sciencedaily.com)     Original source 

For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.

Meadow Spittlebug's record-breaking diet also makes it top disease carrier for plants      (via sciencedaily.com)     Original source 

New research fueled in part by citizen scientists reveals that the meadow spittlebug—known for the foamy, spit-like urine released by its nymphs—can feed on at least 1,300 species of host plants, more than twice the number of any other insect.
