Ecologists have identified significant ecological risks associated with the release of hybrid groupers into Hong Kong's coastal waters, a practice often linked to religious 'mercy release' rituals. Their study highlights how the Tiger Grouper-Giant Grouper hybrid (TGGG), also known as the Sabah grouper, disrupts local marine ecosystems by exploiting unique ecological niches and potentially becoming a dominant predator. This research, the first to use advanced DNA metabarcoding to analyze the diet of this hybrid species, underscores the urgent need for public education and conservation measures to mitigate unintended ecological impacts.View the full article

Researchers, citizen scientists and their 'truffle dogs' -- have discovered two new species of truffle. Tuber canirevelatum, meaning the 'dog-found' truffle, was named in honor of truffle dogs and Monza, the dog who discovered it with her trainer Lois Martin. The other, Tuber cumberlandense, was named for the Cumberland Plateau where it was found by Margaret Townsend and her truffle dog, Luca.View the full article

A mussel bed in Northern California is as healthy and biodiverse as it was about 80 years ago, when two young students surveyed it shortly before one was sent to fight in World War II. Resampling the site reveals a thriving mussel bed community that also shows the mark of climate change.View the full article

Northern pike are moving through salt water to invade freshwater habitats in Southcentral Alaska, according to a new study. It's the first known documentation that northern pike are traveling through estuaries, where fresh water from rivers mixes with the ocean, to colonize new territory in North America.View the full article

Route of entry for Semliki Forest virus into the brain revealed
NewsBot posted a topic in NISIC News
Semliki Forest virus was originally isolated from mosquitoes in the Semliki Forest, Uganda, hence the name. Upon systemic infection from mosquito bites, Semliki Forest virus causes mild blood viremia before finding its way to the central nervous system where it can cause neurotoxicity. In a recent study, researchers show that the Semliki Forest virus enters the central nervous system by first entering the cerebrospinal fluid and then binding to a specific cell type before penetrating deeper into the brain. This finding could potentially be used to develop the Semliki Forest virus as an agent for treating brain cancer.View the full article -
The invasive emerald ash borer, according to the U.S. Department of Agriculture, was first found in the United States in southeast Michigan in 2002. In the decades since, the wood-boring beetle has spread east and west across the U.S. and Canada, killing tens of millions of ash trees, causing one of the costliest forest insect invasions to date. More than 90% of all ash infested by the insect native to Asia eventually die, threatening to make the tree species functionally extinct in North America. In response, researchers are working to identify and develop ash trees genetically able to withstand the beetles' onslaught and strategize how to restore ash to forests.View the full article

A research team has carried out the most comprehensive assessment to date of how logging and conversion to oil palm plantations affect tropical forest ecosystems. The results demonstrate that logging and conversion have significantly different and cumulative environmental impacts.View the full article

Scorching climate drove lampreys apart during cretaceous period
NewsBot posted a topic in NISIC News
A new study finds that one of the hottest periods in Earth's history may have driven lampreys apart -- genetically speaking. The work could have implications for how aquatic species respond to our current changing climate.View the full article -
Biologists have revealed genetics behind the alternating sexes of walnut trees. The research reveals a mechanism that has been stable in walnuts and their ancestors going back 40 million years -- and which has some parallels to sex determination in humans and other animals.View the full article

A new species of black, slender moray eel has chosen the road less traveled, thriving in dim and muddy river mouths, unlike most of its marine relatives. It is found across the Central Indo-Pacific, including within the cave of the Puerto Princesa Subterranean River. This new moray eel is named after the underworld god Hades for its distinctive habitat, unique behaviors, and most notably, its deep, dark coloration.View the full article

Researchers have named six new tree species based on comparisons made among collections of dried plant specimens from across the Neotropics. Of these six, three of the new species have only been found in Panama: Matisia petaquillae, Matisia changuinolana and Matisia aquilarum. The new species from Colombia identified in the same report are Matisia genesiana, Matisia mutatana and Matisia rufula.View the full article

California's native wildflowers are being smothered by layers of dead, invasive grasses. A new study shows that simply raking these layers can boost biodiversity and reduce fire danger.View the full article

After several years of service under harsh weather conditions, the rotor blades of offshore wind parks are subjected to degradation and surface erosion, releasing sizeable quantities of particle emissions into the environment. A team of researchers has now investigated the effects of these particle on blue mussels -- a species also being considered for the multi-use of wind parks for aquaculture.View the full article

Economists looked at test scores and school attendance for Chicago-area kids before and after a bug infestation wiped out the city's ash trees. Education outcomes for low-income students went down, highlighting how the impacts of ecosystem degradation are disproportionately felt by disadvantaged communities.View the full article

New research shows that many wildlife species in the U.S., like the endangered giant kangaroo rat, will face much more frequent and severe droughts in the future. By 2050-2080, year-long droughts could happen almost five times as often, and three-year droughts almost seven times as often compared to past decades. These changes will require animals to adapt significantly. Scientists have identified areas with high biodiversity and high risk that can help managers focus attention for conservation efforts. The southwestern U.S. is a critical area where many species will be more affected by increased droughts.View the full article

A new analysis reveals that overfishing has caused populations of chondrichthyan fishes -- sharks, rays, and chimaeras -- to decline by more than 50 per cent since 1970. To determine the consequences, a team of researchers developed an aquatic Red List Index (RLI) which shows that the risk of extinction for chondrichthyan has increased by 19 per cent. The study also highlights that the overfishing of the largest species in nearshore and pelagic habitats could eliminate up to 22 per cent of ecological functions. Chondrichthyans are an ancient and ecologically diverse group of over 1,199 fishes that are increasingly threatened by human activities. Overexploitation by target fisheries and incidental capture (bycatch), compounded by habitat degradation, climate change and pollution, has resulted in over one-third of chondrichthyans facing extinction.View the full article

Scientists have today announced the discovery of a species of lipstick vine completely new to science, from the depths of the Philippine rainforest. The team of botanists made the discovery during an expedition to the remote Barangay Balbalasang rainforest on the island of Luzon in 2022. This almost impenetrable wilderness takes days to reach and has to be hacked through by a machete. The team stayed with the Banao Tribe, an indigenous community who protect their local forest.View the full article
