Rare ant species rediscovered in North Carolina trees      (via sciencedaily.com)     Original source 

There's a species of ant that is so rare, only a handful of records exist from across the entire eastern United States. North Carolina State University researcher Michelle Kirchner not only found these ants in the Triangle region of North Carolina, she is the first to document an entire colony for scientists, taxonomists and ant-thusiasts everywhere. It is the first time males of the species have been collected or photographed.

Broadband buzz: Periodical cicadas' chorus measured with fiber optic cables      (via sciencedaily.com)     Original source 

Through an emerging technology called distributed fiber optic sensing, cables bringing high-speed internet to American households can be used to detect temperature changes, vibrations, and even sound. And periodical cicadas -- the insects that emerge by the billions every 13 or 17 years and make a racket with their mating calls -- are loud enough to be detected. A new study shows how fiber optic sensing could open new pathways for charting populations of these famously ephemeral bugs.

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.

Small marine creatures swimming in plastic chemicals not reproducing      (via sciencedaily.com)     Original source 

Plastic waste in the water might be stopping -- or interrupting -- some shrimp-like creatures from reproducing. In a unique study, the ability of 'shrimp like' creatures to reproduce successfully was found to be compromised by chemicals found in everyday plastics.

The venom preceded the stinger: Genomic studies shed light on the origins of bee venom      (via sciencedaily.com)     Original source 

Bees, wasps and ants belong to the Hymenoptera order and inject a whole cocktail of venomous ingredients when they sting. Despite their tremendous ecological and economic importance, little was previously known about the origins of their venom. Through extensive genomic studies, a team of researchers has now discovered that typical venomous components were already present in the earliest ancestors of Hymenoptera and must therefore have evolved before the stingers of bees and other insects. What's more, and contrary to previous assumptions, the gene for the venom melittin is found solely in bees.

Fish ecologist's research indicates need to conserve iconic migratory snook in Mexico      (via sciencedaily.com)     Original source 

Biologists investigated the snook’s almost 400-mile migration up into the rainforest habitat of the Usumacinta River. They have found that the snook, which connect aquatic food webs and support fisheries, spawn and start their lives in coastal nursery habitats before moving into river habitats that offer an array of food resources.

Pioneering research method reveals bluefin tuna's fate      (via sciencedaily.com)     Original source 

The Mediterranean spawning grounds of Bluefin tuna -- the largest tuna and one of the most powerful fish in the sea -- are under threat, due to rising sea temperatures. A pioneering research method to decode bluefin 'otoliths' (a stony tissue found in their ear) has determined the threshold sea temperature at which bluefin thrive to be 28 degrees Celsius.

The Fens of eastern England once held vast woodlands      (via sciencedaily.com)     Original source 

The Fens of eastern England, a low-lying, extremely flat landscape dominated by agricultural fields, was once a vast woodland filled with huge yew trees, according to new research. Scientists have studied hundreds of tree trunks, dug up by Fenland farmers while ploughing their fields. The team found that most of the ancient wood came from yew trees that populated the area between four and five thousand years ago.

How do temperature extremes influence the distribution of species?      (via sciencedaily.com)     Original source 

As the planet gets hotter, animal and plant species around the world will be faced with new, potentially unpredictable living conditions, which could alter ecosystems in unprecedented ways. A new study investigates the importance of temperature in determining where animal species are currently found to better understand how a warming climate might impact where they might live in the future.

First comprehensive look at effects of 2020-2021 California megafires on terrestrial wildlife habitat      (via sciencedaily.com)     Original source 

In 2020 and 2021, California experienced fire activity unlike anything recorded in the modern record. When the smoke cleared, the amount of burned forest totaled ten times more than the annual average going back to the late 1800s. We know that wildlife in western forests evolved with changing habitat and disturbances like wildfire. Each species responds differently, some benefiting from openings, others losing critical habitat. What we don't know is how increasing fire severity at large scales is impacting their habitat and survival, because many species are not adapted to these types of 'megafires.'
