Published Archaeologists report earliest evidence for plant farming in east Africa (via sciencedaily.com) Original source
A trove of ancient plant remains excavated in Kenya helps explain the history of plant farming in equatorial eastern Africa, a region long thought to be important for early farming but where scant evidence from actual physical crops has been previously uncovered.
Published First local extinction in the US due to sea level rise, study suggests (via sciencedaily.com) Original source
The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published How a plant app helps identify the consequences of climate change (via sciencedaily.com) Original source
A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published Ancient large kangaroo moved mainly on four legs, according to new research (via sciencedaily.com) Original source
A type of extinct kangaroo that lived during the Pleistocene around two and a half million to ten thousand years ago, known as the 'giant wallaby', was a poor hopper, a study has found.
Published Study projects major changes in North Atlantic and Arctic marine ecosystems due to climate change (via sciencedaily.com) Original source
New research predicts significant shifts in marine fish communities in the North Atlantic and Arctic Oceans as a result of climate warming.
Published Near chromosome-level genome of the Mojave poppy bee (via sciencedaily.com) Original source
Scientists have developed a near chromosome-level genome for the Mojave poppy bee, a specialist pollinator of conservation concern.
Published Study illuminates cues algae use to 'listen' to their environment (via sciencedaily.com) Original source
New research shows how a small group of single-celled algae are able to use chemical cues to communicate stress information. Understanding this ability, once thought unique to plants, helps illuminate the complex evolutionary history of plants and algae.
Published The evidence is mounting: humans were responsible for the extinction of large mammals (via sciencedaily.com) Original source
Human hunting, not climate change, played a decisive role in the extinction of large mammals over the last 50,000 years. This conclusion comes from researchers who reviewed over 300 scientific articles from many different fields of research.
Published Choose where to plant energy crops wisely to minimise loss of biodiversity (via sciencedaily.com) Original source
In the fight to protect biodiversity and limit climate change, the world will reap what it sows.
Published This desert moss has the potential to grow on Mars (via sciencedaily.com) Original source
The desert moss Syntrichia caninervis is a promising candidate for Mars colonization thanks to its extreme ability to tolerate harsh conditions lethal to most life forms. The moss is well known for its ability to tolerate drought conditions, but researchers now report that it can also survive freezing temperatures as low as 196 C, high levels of gamma radiation, and simulated Martian conditions involving these three stressors combined. In all cases, prior dehydration seemed to help the plants cope.
Published Projected loss of brown macroalgae and seagrasses with global environmental change (via sciencedaily.com) Original source
Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.
Published Groundbreaking discovery: Zinc can make crop yields more climate-resilient (via sciencedaily.com) Original source
Climate change, drought, increased temperature and other stressors challenge agricultural sustainability. Researchers have now made an unexpected discovery: zinc plays a pivotal role in the plant response to abiotic stress. This groundbreaking discovery not only sheds light on the intricate mechanisms of plant growth but also holds promise for revolutionizing crop resilience, especially in legume-based agriculture.
Published Last surviving woolly mammoths were inbred but not doomed to extinction (via sciencedaily.com) Original source
The last population of woolly mammoths was isolated on Wrangel Island off the coast of Siberia 10,000 years ago, when sea levels rose and cut the mountainous island off from the mainland. A new genomic analysis reveals that the isolated mammoths, who lived on the island for the subsequent 6,000 years, originated from at most 8 individuals but grew to 200--300 individuals within 20 generations. The researchers report that the Wrangel Island mammoths' genomes showed signs of inbreeding and low genetic diversity but not to the extent that it can explain their ultimate (and mysterious) extinction.
Published New tool enables faster, more cost-effective genome editing of traits to improve agriculture sustainability (via sciencedaily.com) Original source
New research had the goal of reducing the time and cost it takes to bring an improved crop to the marketplace to improve agriculture sustainability.
Published Rewriting the armadillo family tree: A new species, plus a name change for the state mammal of Texas (via sciencedaily.com) Original source
The nine-banded armadillo, which ranges all the way from Argentina to Nebraska, is actually four separate species. One of the species, the Guianan long-nosed armadillo, is new to science. Meanwhile, the species that has migrated from Mexico to the United States (and is the official small mammal of Texas) is now called the Mexican long-nosed armadillo.
Published Frog 'saunas' a lifeline for endangered frog populations (via sciencedaily.com) Original source
New biologist-designed shelters will help endangered frogs survive the devastating impacts of a deadly fungal disease by regulating their body temperature to fight off infections.
Published Removal of excess chloride ions by plants when subjected to salt stress (via sciencedaily.com) Original source
Researchers have discovered a salt adaptation mechanism in plants that facilitates chloride removal from the roots and enhancing salinity tolerance. A research team has uncovered a novel mechanism of plant adaptation to salt stress involving the NaCl-induced translocation of a specific chloride channel protein, AtCLCf.
Published Boosting biodiversity without hurting local economies (via sciencedaily.com) Original source
Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.
Published Wild chimpanzees seek out medicinal plants to treat illness and injuries (via sciencedaily.com) Original source
Chimpanzees appear to consume plants with medicinal properties to treat their ailments, according to a new study.
Published Climate models underestimate carbon cycling through plants (via sciencedaily.com) Original source
The carbon stored globally by plants is shorter-lived and more vulnerable to climate change than previously thought, according to a new study.
