Published Urban ponds require attention to ensure biodiversity
(via sciencedaily.com) New research suggests aquatic plants can be utilized as a tool to enhance the co-existence between aquatic invertebrates and their fish predators in urban ponds.
Published Sea stars able to consume kelp-eating urchins fast enough to protect kelp forests, research shows
(via sciencedaily.com) Researchers have provided the first experimental evidence that a species of endangered sea star protects kelp forests along North America's Pacific Coast by preying on substantial numbers of kelp-eating urchins.
Published As sea ice declines in the Arctic, bowhead whales are adjusting their migration patterns
(via sciencedaily.com) As sea ice declines in the Arctic, bowhead whales are staying north of the Bering Strait more frequently, a shift that could affect the long-term health of the bowhead population and impact the Indigenous communities that rely on the whales, a new study shows.
Published Meteorite crater discovered in French winery
(via sciencedaily.com) Countless meteorites have struck Earth in the past and shaped the history of our planet. It is assumed, for example, that meteorites brought with them a large part of its water. The extinction of the dinosaurs might also have been triggered by the impact of a very large meteorite. It turns out that the marketing 'gag' of the 'Domaine du Météore' winery is acutally a real impact crater. Meteorite craters which are still visible today are rare because most traces of the celestial bodies have long since disappeared again.
Published Researchers put plant protein mechanism into bacteria to help move forward 50 years of effort
(via sciencedaily.com) Researchers have added components of plant chloroplasts to bacteria. This feat, 50 years in the making, allows them to analyze the proteins in greater detail in order to improve Rubisco, and eventually photosynthesis.
Published Climate 'spiral' threatens land carbon stores
(via sciencedaily.com) The world's forests are losing their ability to absorb carbon due to increasingly 'unstable' conditions caused by humans, a landmark study has found.
Published New research reveals 12 ways aquaculture can benefit the environment
(via sciencedaily.com) Aquaculture, or the farming of aquatic plants and animals, contributes to biodiversity and habitat loss in freshwater and marine ecosystems globally, but when used wisely, it can also be part of the solution, new research shows.
Published Sheep can benefit urban lawn landscapes and people
(via sciencedaily.com) About 25 woolly sheep who seasonally -- for the past two years -- leave barns to nibble on lawns at various central campus locations, are doing much more than mowing, fertilizing and improving the ecosystem. The sheep also are improving people's mental health.
Published Detecting the impact of drought on plants with user-friendly and inexpensive techniques
(via sciencedaily.com) Climate change is aggravating the impact of droughts -- one of the factors that only affect plant physiology -- on all plant ecosystems worldwide. Although new tools have been developed to detect and assess drought stress in plants -- transcriptomic or metabolomic technologies, etc. -- they are still difficult to apply in natural ecosystems, especially in remote areas and developing countries.
Published Researchers map mosquito cells that may help the insects choose tastiest humans
(via sciencedaily.com) In a bid to understand why mosquitoes may be more attracted to one human than another, researchers say they have mapped specialized receptors on the insects' nerve cells that are able to fine-tune their ability to detect particularly 'welcoming' odors in human skin.
Published Noble false widow spider found preying on pygmy shrew
(via sciencedaily.com) Scientists have published the first record of a noble false widow spider feeding on a pygmy shrew, a species of tiny mammal protected in Ireland. The pygmy shrew -- a protected mammal -- was captured on spider's web on a bedroom window, then paralyzed and hoisted to its doom by the invasive spider.
Published Geckos know their own odor
(via sciencedaily.com) Geckos can use their tongue to differentiate their own odor from that of other members of their species, as researchers have shown in a new experimental study. The findings show that geckos are able to communicate socially, meaning that they are more intelligent than was previously assumed.
Published Food quality matters for southern resident killer whales
(via sciencedaily.com) Not all Chinook salmon are created equal, and this has a major impact on the energetics for southern resident killer whales. A recent study quantified the lipid content in Fraser River Chinook salmon -- the southern resident's preferred meal -- and found that spring-run Chinook salmon, the earliest to arrive to the Salish Sea are lipid-rich and energy dense; a critical factor for the killer whales who prey on them. Fraser River Chinook salmon that come later in the season have lower energy density.
Published Canine distemper now threatens big cats in Nepal
(via sciencedaily.com) Original source Researchers have confirmed the first cases of canine distemper virus (CDV), which can cause fatal neurological disease, in tigers and leopards in Nepal.
Published Amazon mammals threatened by climate change
(via sciencedaily.com) Most land-based mammals in the Brazilian Amazon are threatened by climate change and the savannization of the region.
Published How the fastest fish hunts its prey
(via sciencedaily.com) Scientists have designed a novel electronic tag package incorporating high-tech sensors and a video camera in order to document a detailed view of exactly how sailfish behave and hunt once they are on their own and out of view of the surface.
Published Kangaroo fecal microbes could reduce methane from cows
(via sciencedaily.com) Baby kangaroo feces might help provide an unlikely solution to the environmental problem of cow-produced methane. A microbial culture developed from the kangaroo feces inhibited methane production in a cow stomach simulator. After researchers added the baby kangaroo culture and a known methane inhibitor to the simulated stomach, it produced acetic acid instead of methane. Unlike methane, which cattle discard as flatulence, acetic acid has benefits for cows as it aids muscle growth.
Published Rats trade initial rewards for long-term learning opportunities
(via sciencedaily.com) Scientists have provided evidence for the cognitive control of learning in rats, showing they can estimate the long-term value of learning and adapt their decision-making strategy to take advantage of learning opportunities.
Published Scientists find world's oldest European hedgehog
(via sciencedaily.com) The world's oldest scientifically-confirmed European hedgehog has been found in Denmark by a citizen science project involving hundreds of volunteers. The hedgehog lived for 16 years, 7 years longer than the previous record holder.
Published Oldest spinosaur brains revealed
(via sciencedaily.com) Researchers have reconstructed the brains and inner ears of two British spinosaurs, helping uncover how these large predatory dinosaurs interacted with their environment.
