Published Research questions value of sagebrush control in conserving sage grouse
(via sciencedaily.com) Original source Sagebrush reduction strategies, including mowing and herbicide application, are often employed to enhance habitat for the greater sage grouse and other sagebrush-dependent species.
Published How coral reefs can survive climate change
(via sciencedaily.com) Original source Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.
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 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 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 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 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 Coral disease tripled in the last 25 years. Three-quarters will likely be diseased by next century
(via sciencedaily.com) Original source Research suggests warming temperatures will see nearly 80 per cent of coral in reefs diseased in the next 80 years.
Published Viruses hidden in coral symbiont's genetic material are a potential threat to reefs
(via sciencedaily.com) Original source Microscopic algae that corals need for survival harbor a common and possibly disease-causing virus in their genetic material.
Published Whales not to be counted on as 'climate savers'
(via sciencedaily.com) Original source Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The team found the amount potentially sequestered by the whales was too minimal to make significant impact on the trajectory of climate change.
Published The other side of the story: How evolution impacts the environment
(via sciencedaily.com) Original source Researchers show that an evolutionary change in the length of lizards' legs can have a significant impact on vegetation growth and spider populations on small islands in the Bahamas. This is one of the first times, the researchers say, that such dramatic evolution-to-environment effects have been documented in a natural setting.
Published Forest protection and carbon dioxide stored in biomass
(via sciencedaily.com) Original source A study has found that worldwide protected forests have an additional 9.65 billion metric tons of carbon stored in their above-ground biomass compared to ecologically similar unprotected areas.
Published Forest birds with short, round wings more sensitive to habitat fragmentation
(via sciencedaily.com) Original source Tropical forest birds, which tend to have wings that are short and round relative to their body length and shape, are more sensitive to habitat fragmentation than the long-, slender-winged species common in temperate forests.
Published Study identifies boat strikes as a growing cause of manatee deaths in Belize
(via sciencedaily.com) Original source The endangered Antillean manatee faces a growing threat from boat strikes in Belize, according to a new study that raises concerns about the survival of what had been considered a relatively healthy population. Belize hosts a population of around 1,000 manatees. With the growth of tourism in recent decades, however, Belize has seen a substantial increase in boat traffic, making boat strikes an increasingly important cause of manatee deaths and injuries.
Published Mitigating climate change through restoration of coastal ecosystems
(via sciencedaily.com) Original source Researchers are proposing a novel pathway through which coastal ecosystem restoration can permanently capture carbon dioxide from the atmosphere. Seagrass and mangroves -- known as blue carbon ecosystems -- naturally capture carbon through photosynthesis, which converts carbon dioxide into living tissue.
Published Global macrogenetic map of marine habitat-forming species
(via sciencedaily.com) Original source Species known as marine habitat-forming species -- gorgonians, corals, algae, seaweeds, marine phanerogams, etc.-- are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide biomass and complexity to the seabeds. But these key species in marine ecosystems are currently threatened by climate change and other perturbations derived from human activity. Now, a study warns that even in the marine protected areas (MPAs) the genetic diversity of structural species is not protected, although it is essential for the response and adaptation of populations to changes that alter the natural environment.
Published Prescribed burns encourage foul-smelling invaders
(via sciencedaily.com) Original source Though prescribed burns reduce wildfire threats and even improve habitat for some animals, new research shows these fires also spread stinknet, an aptly named weed currently invading superblooms across the Southwestern U.S.
Published Corals mark friendly algae for ingestion -- revealing possible conservation target
(via sciencedaily.com) Original source Biologists reveals how coral cells tag friendly algae before ingesting them, initiating a mutually beneficial relationship. This information could guide next-level coral conservation efforts.
Published Wildfire spread risk increases where trees, shrubs replace grasses
(via sciencedaily.com) Original source A new study found that as woody plants like shrubs and trees replace herbaceous plants like grasses, spot fires can occur farther away from the original fire perimeter.
