Published Preventing the destruction of Eucalyptus forest plantations: Naturally occurring pathogenic fungi to control the Eucalyptus snout beetle
(via sciencedaily.com) Original source Scientists have found naturally occurring pathogenic fungi infecting the Eucalyptus snout beetle in Eucalyptus forest plantations, and characterized them to develop a bio-pesticide for controlling the beetle.
Published Some mosquitoes like it hot
(via sciencedaily.com) Original source Certain populations of mosquitoes are more heat tolerant and better equipped to survive heat waves than others, according to new research.
Published Microbial awakening restructures high-latitude food webs as permafrost thaws
(via sciencedaily.com) Original source Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.
Published Western Cascades landscapes in Oregon historically burned more often than previously thought
(via sciencedaily.com) Original source Forests on the west slope of Oregon's Cascade Range experienced fire much more often between 1500 and 1895 than had been previously thought.
Published New reptile on the block: A new iguana species discovered in China
(via sciencedaily.com) Original source Researchers have identified a new iguana species, Wang's garden lizard (Calotes wangi), in southern China and northern Vietnam. This species, part of the Calotes versicolor complex, was discovered through extensive surveys conducted from 2009 to 2022. Measuring less than 9 cm with an orange tongue, it inhabits subtropical and tropical forests, thriving in various landscapes including urban areas.
Published How technology and economics can help save endangered species
(via sciencedaily.com) Original source A lot has changed in the world since the Endangered Species Act (ESA) was enacted 50 years ago in December 1973. Experts are now discuss how the ESA has evolved and what its future might hold.
Published How national policies affect forests in border regions
(via sciencedaily.com) Original source How do national policies impact deforestation? Researchers have looked into this question at the global scale and have found that, contrary to common assumptions, national strategies have a significant -- and visible -- influence on efforts to protect forest heritage.
Published Tree plantations can get better with age -- but original habitats are best
(via sciencedaily.com) Original source Older tree plantations can be more attractive to animals who are looking for a new home than younger plantations, according to a new study. In the tropics, older plantations also welcome a greater variety of different plants and animals -- though sadly, Christmas tree plantations do not become more biodiverse over time.
Published Same and different: A new species of pit viper from Myanmar
(via sciencedaily.com) Original source Asian pit vipers of the genus Trimeresurus are notoriously difficult to tell apart and continue puzzling researchers to this day. Some species groups have similar-looking species (different species that look alike), while others exhibit extreme variation within a single species (same species that look different). Scientists have now discovered a new species of pit viper from Myanmar that is both similar and different from its adjacent sister species.
Published New larks revealed in Africa
(via sciencedaily.com) Original source Researchers have studied the relationships between five closely related species of larks that occur in Africa south of the Sahara. Two of these have not been observed for decades, so the researchers analyzed DNA from museum specimens, some of which were over 100 years old.
Published Global inventory of sound production brings us one step closer to understanding aquatic ecosystems
(via sciencedaily.com) Original source Our understanding of which aquatic species produce sounds just took a big step forward. Scientists have created an inventory of species confirmed or expected to produce sound underwater.
Published Hotter weather caused by climate change could mean more mosquitoesv
(via sciencedaily.com) Original source Research along James River in Richmond suggests that climate change could shorten window for predators to prey on larvae.
Published Trees in wetter regions more sensitive to drought
(via sciencedaily.com) Original source This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it's likely been spoiled for generations.
Published How forests smell -- a risk for the climate?
(via sciencedaily.com) Original source Plants emit odors for a variety of reasons, such as to communicate with each other, to deter herbivores or to respond to changing environmental conditions. An interdisciplinary team of researchers carried out a study to investigate how biodiversity influences the emission of these substances. For the first time, they were able to show that species-rich forests emit less of these gases into the atmosphere than monocultures. It was previously assumed that species-rich forests release more emissions. The Leipzig team has now been able to disprove this assumption experimentally.
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 Nature and animal emojis don't accurately represent natural biodiversity
(via sciencedaily.com) Original source The current emoji library doesn't accurately represent the 'tree of life' and the breadth of biodiversity seen in nature according to a new analysis. A team of conservation biologists categorized emojis related to nature and animals and mapped them onto the phylogenetic tree of life. They found that animals are well represented by the current emoji catalog, whereas plants, fungi, and microorganisms are poorly represented. Within the animal kingdom, vertebrates were over-represented while arthropods were underrepresented with respect to their actual biodiversity.
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 New insights into Zebra mussel attachment fibers offer potential solutions to combat invasive species, develop sustainable materials
(via sciencedaily.com) Original source A recent study has revealed that an unlikely event, occurring over 12 million years ago played an important role in shaping one of Canada's most damaging invasive species. Zebra and quagga mussels, belonging to the Dreissenid family, are widespread freshwater invasive species throughout North America that present a significant danger to native ecosystems by competing for resources. Using a fibrous anchor called a byssus, Dreissenid mussels contribute to biofouling on surfaces and obstruct intake structures in power stations and water treatment plants.
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 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.
