Published Earth's earliest forest revealed in Somerset fossils
(via sciencedaily.com) Original source The oldest fossilized forest known on Earth -- dating from 390 million years ago -- has been found in the high sandstone cliffs along the Devon and Somerset coast of South West England.
Published Eight new deep-sea species of marine sponges discovered
(via sciencedaily.com) Original source Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.
Published Microbes impact coral bleaching susceptibility
(via sciencedaily.com) Original source A new study provides insights into the role of microbes and their interaction as drivers of interspecific differences in coral thermal bleaching.
Published Invasive plant time bombs: A hidden ecological threat
(via sciencedaily.com) Original source Invasive plants can stay dormant for decades or even centuries before rapidly expanding and wreaking ecological havoc, finds a new study.
Published New deep-sea worm discovered at methane seep off Costa Rica
(via sciencedaily.com) Original source Marine biologists have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica.
Published Fossil named 'Attenborough's strange bird' was the first in its kind without teeth
(via sciencedaily.com) Original source A new fossil, named 'Attenborough's strange bird' after naturalist and documentarian Sir David Attenborough, is the first of its kind to evolve a toothless beak. It's from a branch of the bird family tree that went extinct in the mass extinction 66 million years ago, and this strange bird is another puzzle piece that helps explain why some birds -- and their fellow dinosaurs -- went extinct, and others survived to today.
Published Scientists ID burned bodies using technique used for extracting DNA from woolly mammoths, Neanderthals
(via sciencedaily.com) Original source A technique originally devised to extract DNA from woolly mammoths and other ancient archaeological specimens can be used to potentially identify badly burned human remains, according to research.
Published How climate change risks increase at a national scale as the level of global warming increases
(via sciencedaily.com) Original source Researchers have quantified how climate change risks to human and natural systems increase at a national scale as the level of global warming increases. A collection of eight studies -- all focusing on Brazil, China, Egypt, Ethiopia, Ghana and India -- shows that the risks of drought, flooding, declines in crop yields, and loss of biodiversity and natural capital greatly increase for each additional degree of global warming. The overarching picture for the accrual of climate risk across these countries as global warming increases from 1.5 C to 4 C above pre-industrial levels is presented.
Published Slimming down a colossal fossil whale
(via sciencedaily.com) Original source A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.
Published Uncertainty in measuring biodiversity change could hinder progress towards global targets for nature
(via sciencedaily.com) Original source More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022. The GBF focuses on understanding why biodiversity is declining and what actions are needed to reverse this trend. However, according to researchers, implementing the plan is challenging because information about biodiversity changes is not evenly available everywhere, and is uncertain in many places.
Published Bottlenecks and beehives: How an invasive bee colony defied genetic expectations
(via sciencedaily.com) Original source An invasive Asian honeybee colony in northern Australia has defied expectations, displaying emergent genetic variation in a short period of time. While bad news for biosecurity agencies, it could be a sign that species under pressure from climate change can be resilient.
Published Older African elephants will be most severely affected by the changing climate
(via sciencedaily.com) Original source Older elephants in East Africa will be most severely impacted by climate change, threatening the long-term survival of this vulnerable African mammal, according to a new study.
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 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 High resolution techniques reveal clues in 3.5 billion-year-old biomass
(via sciencedaily.com) Original source To learn about the first organisms on our planet, researchers have to analyze the rocks of the early Earth. These can only be found in a few places on the surface of the Earth. The Pilbara Craton in Western Australia is one of these rare sites: there are rocks there that are around 3.5 billion years old containing traces of the microorganisms that lived at that time. A research team has now found new clues about the formation and composition of this ancient biomass, providing insights into the earliest ecosystems on Earth.
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 Panama Canal expansion rewrites history of world's most ecologically diverse bats
(via sciencedaily.com) Original source In a new study, paleontologists describe the oldest-known leaf-nosed bat fossils, which were found along the banks of the Panama Canal. They're also the oldest bat fossils from Central America, preserved 20-million years ago when Panama and the rest of North America were separated from southern landmass by a seaway at least 120 miles wide.
