Published Invasive spotted lanternfly may not damage hardwood trees as previously thought
(via sciencedaily.com) Original source In 2012, when the spotted lanternfly (Lycorma delicatula) arrived in the U.S. from its home in China, scientists, land managers, and growers were understandably concerned that the sap-feeding insect would damage native and commercial trees. New long-term research has discovered that hardwood trees, such as maple, willow and birch, may be less vulnerable than initially thought.
Published Evolutionary imbalance explains global plant invasions
(via sciencedaily.com) Original source Plant species from certain geographic regions are more successful in spreading outside their native ranges than others -- but why? Ecologists provide answers by exploring how the ecological and evolutionary histories of plants can influence their relationships with humans and their success as invaders.
Published Can this forest survive? Predicting forest death or recovery after drought
(via sciencedaily.com) Original source New work could help forest managers predict which forests are most at risk from drought and which will survive.
Published Want to fight climate change? Don't poach gorillas (or elephants, hornbills, toucans, etc.)
(via sciencedaily.com) Original source A new article found that overhunting of gorillas, elephants, and other large fruit-eating seed-dispersers make tropical forests less able to store or sequester carbon.
Published Saving species from extinction -- high-quality kakapo population sequencing provides breakthrough in understanding key conservation genetics
(via sciencedaily.com) Original source High-quality sequencing of nearly the entire kakapo population is helping New Zealand to manage the health of this critically endangered species.
Published Soils forming on the branches of trees are an overlooked forest habitat
(via sciencedaily.com) A study on 'canopy soils' on old trees in Costa Rica shows they are important habitats and carbon stores that cannot easily be replaced.
Published Deforestation limits nesting habitat for cavity-nesting birds
(via sciencedaily.com) A new study of cavity-nesting birds in Ecuador shows the influence of deforestation on their habitat and reproductive success. Nest boxes could help.
Published Tree mortality in the Black Forest on the rise -- climate change a key driver
(via sciencedaily.com) Original source Climate impacts such as dry, hot summers reduce the growth and increase the mortality of trees in the Black Forest because they negatively influence the climatic water balance, i.e., the difference between precipitation and potential evapotranspiration. That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.
Published Biodiversity protects against invasions of non-native tree species
(via sciencedaily.com) Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.
Published Fire, disease threatening sanctuary plants for Australian wildlife
(via sciencedaily.com) Original source New research has revealed Australia's iconic grasstrees -- known as 'yaccas' -- play a critical role in protecting wildlife from deadly weather extremes, thereby ensuring their survival. But the grasses themselves are under threat due to back burning, clearing and disease.
Published Hundreds of Andean bird species at risk due to deforestation: New research shows how to protect them
(via sciencedaily.com) Original source Birds native to the tropical Andes are threatened by increasing agricultural development in the region. A new study combines a meta-analysis of papers on birds across the Andes with five years of fieldwork in Peru, revealing that open farmlands result in up to a 60% decline in the number of species in an area. The study documents how specific species are affected and provides tailored guidance for conservationists trying to protect them.
Published The modern sea spider had started to diversify by the Jurassic, study finds
(via sciencedaily.com) Original source An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind.
Published City-dwelling wildlife demonstrate 'urban trait syndrome'
(via sciencedaily.com) City life favors species that are adaptable and not too fussy about what they eat, among other characteristics. A worldwide consortium of scientists calls the resulting collection of traits an 'Urban Trait Syndrome.'
Published Managing domestic and wildcats is likely to remain fraught, new research warns
(via sciencedaily.com) Original source Current efforts to protect and restore native biodiversity is being threatened by difficulties in identifying wild and domestic cats, and categorization is likely to remain fraught for the foreseeable future, experts have warned.
Published Study reveals successful strategies for removing invasive caimans from Florida Everglades
(via sciencedaily.com) A new study reveals how a succession of strategies can take control of an invasive species population.
Published Tropical trees use social distancing to maintain biodiversity
(via sciencedaily.com) Original source Tropical forests can harbor hundreds of species of trees in one square mile. Researchers reveal key factors in the spatial distribution of adult trees.
Published Scientists dig into wildfire predictions, long-term impacts
(via sciencedaily.com) Original source Wildfires are an ancient force shaping the environment, but they have grown in frequency, range and intensity in response to a changing climate. Scientists are working on several fronts to better understand and predict these events and what they mean for the carbon cycle and biodiversity.
Published Sea level rise shifts habitat for endangered Florida Keys species
(via sciencedaily.com) Original source A newly published study describes the response to sea level rise by the silver rice rat, an endangered species only found in the Florida Keys.
Published Nuisance vegetation removal in Senegalese waterways reduces the overall prevalence of parasitic infections and increases local food production
(via sciencedaily.com) Original source It's an elegant solution: Remove the habitat of a parasite-carrying aquatic snail and reduce the level of infection in the local community; all while generating more feed and compost for local farmers.
Published When cheating pays -- survival strategy of insect uncovered
(via sciencedaily.com) Original source Researchers have revealed the unique 'cheating' strategy a New Zealand insect has developed to avoid being eaten -- mimicking a highly toxic species.
