Published Twenty-year study confirms California forests are healthier when burned -- or thinned
(via sciencedaily.com) Original source A 20-year experiment in the Sierra Nevada confirms that different forest management techniques -- prescribed burning, restoration thinning or a combination of both -- are effective at reducing the risk of catastrophic wildfire in California. These treatments also improve forest health, making trees more resilient to stressors like drought and bark beetles, and they do not negatively impact plant or wildlife biodiversity within individual tree stands, the research found.
Published The configuration of green spaces in cities determines the characteristics of their birds
(via sciencedaily.com) Original source An international study has analyzed the distribution of 115 species of birds in spring and 72 that spend the winter in different cities. The study provides information on how to design urban areas that favor biodiversity and public wellbeing.
Published Underwater architects: The 'burrowing effect' of foraminifera on marine environments
(via sciencedaily.com) Original source Impact of single-cell organisms on sediment oxygen levels and bacterial diversity measured for the first time.
Published Have researchers found the missing link that explains the mysterious phenomenon known as fairy circles?
(via sciencedaily.com) Original source Fairy circles, a nearly hexagonal pattern of bare-soil circular gaps in grasslands, initially observed in Namibia and later in other parts of the world, have fascinated and baffled scientists for years. New research suggests that all theories to date have overlooked the coupling between two robust mechanisms essential for understanding ecosystem response: phenotypic plasticity at the level of a single plant, and spatial self-organization in vegetation patterns at the level of a plant population.
Published Suburban backyard home to more than 1,000 species
(via sciencedaily.com) Original source A challenge among three housemates to identify species around their inner-Brisbane home has resulted in an academic research paper, showcasing the rich biodiversity in urban landscapes.
Published Coral reefs in peril from record-breaking ocean heat
(via sciencedaily.com) Original source Record breaking marine heatwaves will cause devastating mass coral bleaching worldwide in the next few years, according to a coral reef scientist.
Published Urbanization increases seasonal differences in plant-pollinator networks
(via sciencedaily.com) Original source Increasing urbanization worldwide is a growing threat to biodiversity. At the same time, flowering plants are often more diverse in cities than in the countryside. This is due to flowering plants and agricultural crops, which are increasingly being grown in cities. A recent study shows that the interactions between plants and pollinators, which are important for agricultural production, are surprisingly dynamic. For example, the plant and bee species involved in pollination vary greatly between the seasons.
Published Researchers develop grassroots framework for managing environmental commons
(via sciencedaily.com) Original source A team of sustainability scientists recently announced that they have developed a community-based framework, founded on extensive local and traditional knowledge, to help assess and respond to the kinds of ecological threats that are widely dispersed across a varied landscape and whose solutions are not immediately obvious. The framework, which was developed to address watershed issues in Honduras's Lake Yojoa, is widely applicable to a broad range of threats facing ecological commons wherever they may occur around the world.
Published Feathered friends can become unlikely helpers for tropical coral reefs facing climate change threat
(via sciencedaily.com) Original source Tropical coral reefs are among our most spectacular ecosystems, yet a rapidly warming planet threatens the future survival of many reefs. However, there may be hope for some tropical reefs in the form of feathered friends. A new study has found that the presence of seabirds on islands adjacent to tropical coral reefs can boost coral growth rates on those reefs by more than double.
Published Greenhouse gases in oceans are altered by climate change impact on microbes
(via sciencedaily.com) Original source The ocean is a global life-support system, and climate change causes such as ocean warming, acidification, deoxygenation, and nitrogen-deposition alter the delicate microbial population in oceans. The marine microbial community plays an important role in the production of greenhouse gases like nitrous oxide and methane. Scientists have explored the climate change impact on marine microbes. Their research helps raise awareness about climate change severity and the importance of ocean resources.
Published Top 10 climate science insights unveiled
(via sciencedaily.com) Original source A new report equips policymakers with the latest and most pivotal climate science research from the previous 18 months, synthesized to help inform negotiations at COP28 and policy implementation through 2024 and beyond.
Published In hotter regions, mammals seek forests, avoid human habitats
(via sciencedaily.com) Original source As the climate warms, preserving forest cover will be increasingly important for wildlife conservation, finds a study of North American mammals.
Published Deep sea sensor reveals that corals produce reactive oxygen species
(via sciencedaily.com) Original source A new sensor on the submersible Alvin discovered reactive oxygen species for the first time in deep-sea corals, broadening our understanding of fundamental coral physiology.
Published Crocodile family tree mapped: New light shed on croc evolution
(via sciencedaily.com) Original source Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.
Published Decoding flavonoid metabolism: A closer look at plant-based diets
(via sciencedaily.com) Original source An international team of researchers has elucidated the process by which the major flavonoids naringenin, apigenin, and genistein are metabolized in the body. These findings are fundamental in elucidating the correlation between the metabolism of flavonoids in the body and their potential health benefits.
Published Public gardens contribute to invasives problem
(via sciencedaily.com) Original source Some nonnative plants cultivated in public gardens or arboretums are escaping to become invasive in wild forests.
Published Botany must feature more prominently on the school curriculum to promote awareness of climate change, study warns
(via sciencedaily.com) Original source Children must be taught more about the importance of plants if education about climate change and sustainability is to be effective, experts have warned.
Published Snake skulls show how species adapt to prey
(via sciencedaily.com) Original source By studying the skull shapes of dipsadine snakes, researchers have found how these species of snakes in Central and South America have evolved and adapted to meet the demands of their habitats and food sources.
Published 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.
Published 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.
