Measuring electrical conductivity in microorganisms, approaching understanding of microbial ecosystems      (via sciencedaily.com)     Original source 

Researchers have developed an innovative methodology for measuring the electrical conductivity of microbial communities. This methodology holds promise for the development of batteries and electrochemical sensors using microorganisms and may serve as a pivotal tool in elucidating the role of electricity within microbial ecosystems.

Genetic research revealed several new fern species in tropical America      (via sciencedaily.com)     Original source 

Researchers have clarified the evolutionary history of a previously poorly known group of ferns from the tropical rainforests of America using DNA methods. The study discovered many new fern species, 18 of which have now been given official names and species descriptions.

The Golgi organelle's ribbon structure is not exclusive to vertebrates, contrary to previous consensus      (via sciencedaily.com)     Original source 

Researchers report that the Golgi ribbon, an organelle structure previously thought to be exclusive to vertebrates, is also present in animal taxa, including mollusks, earthworms, and sea urchins. The function of the Golgi ribbon is still enigmatic, but its presence in diverse animal lineages indicates that its function is not vertebrate specific, as previously thought. The team also showed Golgi ribbons form at a specific timepoint during embryogenesis, which suggests that they might play a role in cell differentiation.

Bottlenecks and beehives: How an invasive bee colony defied genetic expectations      (via sciencedaily.com)     Original source 

An invasive Asian honeybee colony in northern Australia has defied expectations, displaying emergent genetic variation in a short period of time. While bad news for biosecurity agencies, it could be a sign that species under pressure from climate change can be resilient.

The veil varies more than the threat: Predator selection on variability in camouflage and warning signals      (via sciencedaily.com)     Original source 

Researchers leveraged open-access digital collections to validate an age-old hypothesis in evolutionary ecology. The classic hypothesis proposes that predators select for a great variety of camouflage and a limited variety of warning signals, but the idea has never been tested on natural prey.

Butterflies mimic each other's flight behavior to avoid predators      (via sciencedaily.com)     Original source 

Researchers have shown that inedible species of butterfly that mimic each others' color patterns have also evolved similar flight behaviors to warn predators and avoid being eaten.

Scientists assemble a richer picture of the plight and resilience of the foothill yellow-legged frog      (via sciencedaily.com)     Original source 

Up to only a few inches in length, with a lemon-hued belly, the foothill yellow-legged frog may seem unassuming. But its range once stretched from central Oregon to Baja California. In 2023, it was listed under the federal Endangered Species Act. Its rapidly decreasing range is due in part to a fungal pathogen called Batrachochytrium dendrobatidis, or Bd, that has devastated amphibians around the world.

Reforestation schemes are not enough to recover the carbon created by harvesting wood      (via sciencedaily.com)     Original source 

Forests have a critical role to play in capturing and storing carbon from the Earth's atmosphere -- but some models exaggerate their carbon removal potential by almost three-fold, according to a leading professor of forest economics.

Birds and bee lessons as Pacific field trips also solve 'Michener's mystery'      (via sciencedaily.com)     Original source 

Eight new Pacific bee species and new insights into Fijian bird behaviour on Viti Levu Island have been described in new scientific studies. The research highlights the potential for species discovery, ecological and conservation knowledge and cultural engagement from Asia-Pacific research collaborations.

Streams connected to groundwater show improved detoxification and microbial diversity      (via sciencedaily.com)     Original source 

Streams with ample connections to shallow groundwater flow-paths have greater microbial diversity and are more effective at preventing toxic forms of metals -- often products of upstream mining -- from entering and being transported downstream.

Snakes do it faster, better: How a group of scaly, legless lizards hit the evolutionary jackpot      (via sciencedaily.com)     Original source 

More than 100 million years ago, the ancestors of the first snakes were small lizards that lived alongside other small, nondescript lizards in the shadow of the dinosaurs.
