Published Extinctions could result as fish change foraging behavior in response to rising temperatures
(via sciencedaily.com) Original source Fish species respond to temperature increases by going after more readily available prey. Models suggest this behavior could lead to more extinctions.
Published Birds and bee lessons as Pacific field trips also solve 'Michener's mystery'
(via sciencedaily.com) Original source Eight new Pacific bee species and new insights into Fijian bird behaviour on Viti Levu Island have been described in new scientific studies. The research highlights the potential for species discovery, ecological and conservation knowledge and cultural engagement from Asia-Pacific research collaborations.
Published Side effects of wide scale forestation could reduce carbon removal benefits by up to a third
(via sciencedaily.com) Original source The side effects of large-scale forestation initiatives could reduce the CO2 removal benefits by up to a third, a pioneering study has found.
Published Mice surprise: Researchers discover new native species
(via sciencedaily.com) Original source Australia can lay claim to two new species of native rodent thanks to a new study. The aptly named delicate mouse was previously thought to be a single species spanning a massive stretch of the country from the Pilbara in Western Australia, across parts of the Northern Territory and through Queensland down to the New South Wales border. We now know there are three distinct species.
Published Modeling tree masting
(via sciencedaily.com) Original source The effects of a phenomenon called tree masting on ecosystems and food webs can be better understood thanks to new theoretical models validated by real world observations.
Published Increasingly similar or different? Centuries-long analysis suggests biodiversity is differentiating and homogenizing to a comparable extent
(via sciencedaily.com) Original source The tendency of communities and the species within them to become more similar or more distinct across landscapes -- biotic homogenization and differentiation -- are approximately balanced, according to a new study. This analysis is the first of its kind to provide a comprehensive assessment of how local and regional biodiversity changes combine across landscapes over centuries.
Published New evidence shows UK solar parks can provide for bees and butterflies
(via sciencedaily.com) Original source A new study shows that UK solar parks, if managed correctly, can provide vital resources to help stem the decline in the nation's bees and butterflies. The new research provides peer-reviewed field data of insect pollinators at solar parks in the UK, covering 15 sites.
Published Converting rainforest to plantation impacts food webs and biodiversity
(via sciencedaily.com) Original source Every day, new areas of rainforests are converted into plantations, drastically changing tropical biodiversity and the way the ecosystem functions. Yet, the current understanding of the consequences is fragmentary: previous studies tended to examine either biodiversity or the ecosystem. An international research team brings these threads together in this study. They analyzed organisms ranging from microscopic mites and earthworms in the soil, to beetles and birds in tree canopies, comparing tropical rainforest with rubber and oil palm plantations in Sumatra, Indonesia.
Published 'The future is fungal': New research finds that fungi that live in healthy plants are sensitive to climate change
(via sciencedaily.com) Original source Findings more than a decade in the making reveal a rich diversity of beneficial fungi living in boreal forest trees, with implications for the health of forests.
Published Gulf corals still suffering more than a decade after Deepwater Horizon oil spill, scientists report
(via sciencedaily.com) Original source Deep-water corals in the Gulf of Mexico are still struggling to recover from the devastating Deepwater Horizon oil spill in 2010, scientists report at the Ocean Science Meeting in New Orleans. Comparing images of more than 300 corals over 13 years -- the longest time series of deep-sea corals to date -- reveals that in some areas, coral health continues to decline to this day.
Published Nature's checkup: Surveying biodiversity with environmental DNA sequencing
(via sciencedaily.com) Original source A thousand kilometers south of Tokyo, far into the largest ocean on Earth, lies a chain of small, volcanic islands -- the Ogasawara Islands. Nature has been able to develop on its own terms here, far from both humans and the warm Kuroshio current, which acts like a shuttle, moving marine species from Taiwan, over the Ryukyu Islands, and up the Pacific coast of mainland Japan. With upwards of 70 % of trees and many animal species being endemic to the archipelago, the islands have been dubbed 'the Galapagos of the East', as they are valuable as both a biodiversity hotspot and a cradle of scientific discovery.
Published Scientists may have cracked the 'aging process' in species
(via sciencedaily.com) Original source Research shows the relationship between a species' age and its risk of going extinct could be accurately predicted by an ecological model called the 'neutral theory of biodiversity.'
Published First-ever report of nesting of incredibly rare and endangered giant turtle
(via sciencedaily.com) Original source Knowledge from local communities has resulted in the first-ever nesting evidence and discovery of a breeding population of an incredibly rare turtle in India.
Published Genetic insights and conservation challenges of Nara's sacred deer
(via sciencedaily.com) Original source In Nara, Japan, the revered sika deer faces a dilemma as their escalating population damages local farmlands. A new study has revealed a complex situation: while the sanctuary's deer upholds a distinct genetic identity, the surrounding areas display a blend of genetic lineages. This exposes a pressing predicament: whether to cull the 'pest' deer around sanctuary or risk losing a sacred genetic legacy.
Published Online digital data and AI for monitoring biodiversity
(via sciencedaily.com) Original source Researchers propose a framework for integrating online digital data into biodiversity monitoring.
Published Searching for clues in the history book of the ocean
(via sciencedaily.com) Original source New research has shown that the tropical subsurface ocean gained oxygen during the Paleocene-Eocene Thermal Maximum (commonly referred to as PETM). During this short-lived interval of time in Earth s history that occurred 56 million years ago the average temperatures rose by up to six degrees within a few thousand years.
Published How is deforested land in Africa used?
(via sciencedaily.com) Original source Africa's forested areas -- an estimated 14 % of the global forest area -- are continuing to decline at an increasing rate -- mostly because of human activities to convert forest land for economic purposes. As natural forests are important CO2 and biodiversity reservoirs, this development has a significant impact on climate change and effects the integrity of nature.
Published Reforestation programs could threaten vast area of tropical grasslands
(via sciencedaily.com) Original source New research reveals the scale of inappropriate reforestation projects across Africa. A new study reveals that an area the size of France is threatened by forest restoration initiatives, such as the AFR100 initiative (African Forest Landscape Restoration Initiative), due to inappropriate restoration in the form of tree-planting.
Published Scientists are unravelling the secrets of red and grey squirrel competition
(via sciencedaily.com) Original source Researchers have identified significant differences between the diversity of gut bacteria in grey squirrels compared to red squirrels which could hold the key to further understanding the ability of grey squirrels to outcompete red squirrels in the UK.
Published Climate change drove the emergence of West Nile virus in Europe
(via sciencedaily.com) Original source Researchers demonstrate the contribution of climate change to the spatial expansion of West Nile virus in Europe, a virus that constitutes a new public health threat in the continent. Their findings highlight a notable increase in the area ecologically suitable for the virus circulation since the beginning of last century and an increase in the human population at risk of exposure, due in part to climate change.
