Published A rise in sea urchins and related damage to kelp forests impacts Oregon's gray whales and their food
(via sciencedaily.com) Original source A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.
Published Can coal mines be tapped for rare earth elements?
(via sciencedaily.com) Original source A team of geologists analyzed 3,500 samples taken in and around coal mines in Utah and Colorado. Their findings open the possibility that these mines could see a secondary resource stream in the form of rare earth metals used in renewable energy and numerous other high-tech applications.
Published 'Vigorous melting' at Antarctica's Thwaites 'Doomsday' Glacier
(via sciencedaily.com) Original source Glaciologists show evidence of warm ocean water intruding kilometers beneath grounded ice at Thwaites Glacier in West Antarctica. The findings suggest that existing climate models are underestimating the impact of ocean and ice interactions in future sea level rise projections.
Published Meerkat chit-chat
(via sciencedaily.com) Original source Researchers unravel the vocal interactions of meerkat groups and show they use two different types of interactions to stay in touch.
Published Evolutionary history of extinct duck revealed
(via sciencedaily.com) Original source The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the Brazilian merganser.
Published Unraveling the drought dilemma: Can reservoirs be a carbon source?
(via sciencedaily.com) Original source A team delves into the spatiotemporal patterns of water volume and total organic carbon concentration of agricultural reservoirs.
Published Extreme complexity in formation of rare earth mineral vital for tech industry
(via sciencedaily.com) Original source Researchers have unveiled that myriad, intricate factors influence the genesis and chemistry of bastnasite and rare earth carbonates, which are critically needed for today's tech industry and its hardware outputs. Their work unveils a newly acquired depth of understanding that had previously been unexplored in this field. In combination, the findings mark a significant advancement and promise to reshape our understanding of rare earth mineral formation.
Published Cloudy waters causes African fish to develop bigger eyes
(via sciencedaily.com) Original source Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study.
Published Subduction zone splay faults compound hazards of great earthquakes
(via sciencedaily.com) Original source Groundbreaking research has provided new insight into the tectonic plate shifts that create some of the Earth's largest earthquakes and tsunamis.
Published After hundreds of years, study confirms Bermuda now home to cownose rays
(via sciencedaily.com) Original source Using citizen science, photographs, on-water observations and the combination of morphological and genetic data, researchers have provided evidence that the Atlantic cownose ray has recently made a new home in Bermuda. Results show that after hundreds of years of natural history records, this is a novel migration of Atlantic cownose rays to Bermuda.
Published Ukraine war caused migrating eagles to deviate from their usual flight plan, study finds
(via sciencedaily.com) Original source When migrating through Ukraine in 2022, Greater Spotted Eagles were exposed to multiple conflict events that altered their migratory course, according to a new study.
Published Scientists develop new geochemical 'fingerprint' to trace contaminants in fertilizer
(via sciencedaily.com) Original source An international team of scientists has revealed high levels of toxic metals in global phosphate fertilizers using a isotopic variants of the element strontium as a tracer to uncover metals in soil, groundwater and possibly the food chain.
Published Scale matters in determining vulnerability of freshwater fish to climate changes
(via sciencedaily.com) Original source A team explored the influence the spatial extent of research -- the geographical coverage of data collected -- has on evaluating the sensitivity of different fish species to climate change.
Published Differing values of nature can still lead to joined up goals for sustainability
(via sciencedaily.com) Original source Recognizing and respecting the different ways nature is valued can enable better environmental decision-making, according to new research.
Published Can we revolutionize the chemical industry and create a circular economy? Yes, with the help of catalysts
(via sciencedaily.com) Original source A new commentary paper puts forth a transformative solution to the unsustainable reliance on fossil resources by the chemical industry: catalysis to leverage sustainable waste resources, ushering the industry from a linear to a circular economy.
Published Study reveals consumers value animal welfare more than environmental sustainability when buying meat and dairy products
(via sciencedaily.com) Original source The treatment of animals rates higher than green issues when consumers choose meat and dairy products. That's according to a new study, which suggests that while consumers consider sustainability important, other factors such as taste, quality, and animal welfare take precedence in their purchasing decisions.
Published Eurasian jays can use 'mental time travel' like humans, study finds
(via sciencedaily.com) Original source Eurasian jays can remember incidental details of past events, which is characteristic of episodic memory in humans, according to a new study.
Published Two decades of studies suggest health benefits associated with plant-based diets
(via sciencedaily.com) Original source Vegetarian and vegan diets are generally associated with better status on various medical factors linked to cardiovascular health and cancer risk, as well as lower risk of cardiovascular diseases, cancer, and death, according to a new review of 49 previously published papers.
Published Summers warm up faster than winters, fossil shells from Antwerp show
(via sciencedaily.com) Original source In a warmer climate, summers warm much faster than winters, according to research into fossil shells. With this knowledge we can better map the consequences of current global warming in the North Sea area.
Published Analyzing androgynous characteristics in an emperor penguin courtship call
(via sciencedaily.com) Original source In the emperor penguin courtship call, male vocalizations are composed of long, slow bursts with lower frequency tones than the female version. But calls of SeaWorld San Diego male penguin E-79 defied this binary. Also unusual was this penguin's male companion, E-81. The pair 'kept company' and sometimes exhibited ritual courtship displays. Researchers studied the courtship calls of E-79 and E-81, recording the birds in their below-freezing enclosure and refining the usual technique for analyzing the bursts.
