Published Human impact on wildlife even in protected areas
(via sciencedaily.com) Original source The largest long-term standardized camera-trap survey to date finds that human activity impacts tropical mammals living in protected areas and sheds light on how different species are affected based on their habitat needs and anthropogenic stressors.
Published Are viruses keeping sea lice at bay in wild salmon?
(via sciencedaily.com) Original source More than 30 previously unknown RNA viruses in sea lice have been identified. Sea lice are parasitic copepods (small crustaceans) found in many fresh and saltwater habitats, and have been implicated in the decline of wild salmon populations. The research sheds greater light on the types of viruses being carried by sea lice, and how the viruses and host are interacting.
Published Traditional methods cannot give us the insights we need to understand changing ecosystems
(via sciencedaily.com) Original source If we want to face up to the challenges posed by climate change and other global environmental changes, we need to bring complexity science into the mix with ecology and biodiversity conservation.
Published Global analysis on pollinators in cities: Wild bees and butterflies are at particular risk
(via sciencedaily.com) Original source Butterflies are being hit hardest by urban growth. Shrinking habitats and food availability are causing their populations to decline. The same applies to many wild bees that fly early in spring. According to a new study, pollination has not yet been impacted by this because honeybees, for example, can compensate for the reduction of urban pollinators. The study is the first comprehensive analysis of the subject and includes data from 133 studies. The results underline the importance of nature conservation measures in urban areas.
Published Glass sponge genome furnishes insights into evolution of biomineralization
(via sciencedaily.com) Original source The genome of a glass sponge species suggests that silica skeletons evolved independently in several groups of sponges.
Published Conservation policies risk damaging global biodiversity, researchers argue
(via sciencedaily.com) Original source Rewilding, organic farming and the 'nature friendly farming' measures included in some government conservation policies risk worsening the global biodiversity crisis by reducing how much food is produced in a region, driving up food imports and increasing environmental damage overseas.
Published 'Shoebox' satellites help scientists understand trees and global warming
(via sciencedaily.com) Original source As scientists try to understand the effect of climate on trees, advances in imaging technology are helping them see both the whole forest and every individual tree. High-resolution images taken by cubesats, small, shoebox-sized devices launched into low Earth orbit, are helping environmental scientists make more precise measurements about trees' response to a warming climate.
Published Caribbean seagrasses provide services worth $255B annually, including vast carbon storage, study shows
(via sciencedaily.com) Original source Caribbean seagrasses provide about $255 billion in services to society annually, including $88.3 billion in carbon storage, according to a new study. The study has put a dollar value on the many services -- from storm protection to fish habitat to carbon storage -- provided by seagrasses across the Caribbean, which holds up to half the world's seagrass meadows by surface area and contains about one-third of the carbon stored in seagrasses worldwide.
Published Climate change could lead to 'widespread chaos' for insect communities
(via sciencedaily.com) Original source New research explores how a warming world could impact ecosystems and derail the development of new species.
Published New research reveals the impact of different species and their traits on human wellbeing
(via sciencedaily.com) Original source New research has revealed that well-functioning ecosystems are crucial to human health and wellbeing, with human-biodiversity interactions delivering wellbeing gains equating to substantial healthcare cost-savings, when scaled-up across populations.
Published Supersized fruit eater database on climate change frontline
(via sciencedaily.com) Original source To conserve precious and fragile biodiversity hotspots, a crucial step is knowing how the fruit eaters are doing. To assist in that, scientists and students have supersized a database to keep track of such animals and birds.
Published AI reveals hidden traits about our planet's flora to help save species
(via sciencedaily.com) Original source Machine learning can help extract important information from the huge numbers of plant specimens stored in herbaria, say scientists.
Published Cryo conservation: A cool solution to saving species from extinction
(via sciencedaily.com) Original source In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.
Published From cross to self-pollination
(via sciencedaily.com) Original source Biologists provide evidence for an alternative genetic mechanism that can lead to plants becoming self-pollinators.
Published Fossil study sheds light on famous spirals found in nature
(via sciencedaily.com) Original source A 3D model of a 407-million-year-old plant fossil has overturned thinking on the evolution of leaves. The research has also led to fresh insights about spectacular patterns found in plants.
Published How will a warming world impact the Earth's ability to offset our carbon emissions?
(via sciencedaily.com) Original source New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.
Published Scientists discover urea in atmosphere revealing profound consequences for climate
(via sciencedaily.com) Original source Areas of the ocean that are rich in marine life are having a bigger impact on our ecosystems and the climate than previously thought, new research suggests.
Published MethaneMapper is poised to solve the problem of underreported methane emissions
(via sciencedaily.com) Original source MethaneMapper is an artificial intelligence-powered hyperspectral imaging tool that researchers have developed to detect real-time methane emissions and trace them to their sources. The tool works by processing hyperspectral data gathered during overhead, airborne scans of the target area.
Published Lost giants: New study reveals the abundance decline of African megafauna
(via sciencedaily.com) Original source A groundbreaking new paper focuses on the size and abundance of living and fossil African large mammals, shedding light on the ecological dynamics behind the decline of these iconic creatures. The findings challenge previous assumptions about the causes of megafaunal extinctions in Africa and provide new insights into the restructuring of ecosystems over millions of years.
Published Team finds reliable predictor of plant species persistence, coexistence
(via sciencedaily.com) Original source Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.
