how far can the wind can carry a plant's seeds? New model      (via sciencedaily.com)     Original source 

Playing an essential foundational role in an ecosystem, plants contribute to the well-being of human health by helping create resources like food and medicine. Therefore, to better understand how plants can maintain resiliency in the face of challenges like climate change, researchers recently developed an innovative mathematical model that can provide fast and reliable predictions of how far wind can carry a plant's seeds.

How shifting climates may have shaped early elephants' trunks      (via sciencedaily.com)     Original source 

Researchers have provided new insights into how ancestral elephants developed their dextrous trunks.  A study of the evolution of longirostrine gomphotheres, an ancestor of the modern day elephant, suggests moving into open-land grazing helped develop their coiling and grasping trunks.

Slash-and-burn agriculture can increase forest biodiversity, researchers find      (via sciencedaily.com)     Original source 

The slash-and-burn agriculture practiced by many Indigenous societies across the world can actually have a positive impact on forests, according to a new study done in Belize. Researchers found that in areas of the rainforest in which Indigenous farmers using slash-and-burn techniques created intermediate-sized farm patches -- neither too small nor too large -- there were increases in forest plant diversity.

Researchers puncture 100-year-old theory of odd little 'water balloons'      (via sciencedaily.com)     Original source 

Quinoa and many other extremely resilient plants are covered with strange balloon-like 'bladders' that for 127 years were believed to be responsible for protecting them from drought and salt. Research results reveal this not to be the case. These so-called bladder cells serve a completely different though important function. The finding makes it likely that even more resilient quinoa plants will now be able to be bred, which could lead to the much wider cultivation of this sustainable crop worldwide.

Sophisticated swarming: Bacteria support each other across generations      (via sciencedaily.com)     Original source 

When bacteria build communities, they cooperate and share nutrients across generations. Researchers have been able to demonstrate this for the first time using a newly developed method. This innovative technique enables the tracking of gene expression during the development of bacterial communities over space and time.

Half of tested caviar products from Europe are illegal, and some aren't even caviar      (via sciencedaily.com)     Original source 

Wild caviar, a pricey delicacy made from sturgeon eggs, has been illegal for decades since poaching brought the fish to the brink of extinction. Today, legal, internationally tradeable caviar can only come from farmed sturgeon, and there are strict regulations in place to help protect the species. However, by conducting genetic and isotope analyses on caviar samples from Bulgaria, Romania, Serbia, and Ukraine -- nations bordering the remaining wild sturgeon populations -- a team of sturgeon experts found evidence that these regulations are actively being broken. Their results show that half of the commercial caviar products they sampled are illegal, and some don't even contain any trace of sturgeon.

Forget social distancing: House finches become more social when sick      (via sciencedaily.com)     Original source 

Social distancing when sick has become second nature to many of us in the past few years, but some sick animals appear to take a different approach. A new study of house finches uncovered a surprising result. Unlike other social animals who passively or actively isolate themselves when sick, this gregarious backyard bird species gravitates toward healthy flock mates when they are sick, even more so than healthy birds do.
