Published Ticks prove resilient to extreme temperatures
(via sciencedaily.com) Original source A recent study shows blacklegged ticks (Ixodes scapularis) are actually really good at surviving extreme cold and heat in nature. Previous lab research suggests that even short periods of especially warm or cold conditions should easily kill ticks, but the a new analysis reveals this is only the case for larval ticks in the environment.
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 flash droughts expected to increase in a warming climate
(via sciencedaily.com) Original source Researchers have published new findings on how our warming climate will affect the frequency of flash droughts and the risk to croplands globally.
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 New method predicts extreme events more accurately
(via sciencedaily.com) Original source A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.
Published Simultaneous atmospheric and marine observations directly beneath a violent, Category 5 typhoon in the North-West Pacific
(via sciencedaily.com) Original source Scientists have successfully conducted a simultaneous marine and atmospheric measurements at multiple locations directly beneath a violent, Category 5, which is the strongest class, typhoon in the North-West Pacific, before it reached land.
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 Modular builds may help construction industry weather a perfect storm
(via sciencedaily.com) Original source Engineers have calculated the potential cost savings for builders who opt for modular construction techniques to avoid lengthy and expensive holdups caused by poor weather.
Published How a drought affects trees depends on what's been holding them back
(via sciencedaily.com) Original source Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.
Published Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world
(via sciencedaily.com) Original source Researchers found that the Hunga-Tonga eruption was associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based communications. Their findings also suggest that a long-held atmospheric model should be revised.
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.
Published In years after El Niño, global economy loses trillions
(via sciencedaily.com) Original source Researchers report that the financial toll of the climate pattern known as El Niño can persist for several years and cost trillions in lost income worldwide. The study, which is among the first to evaluate the long-term costs of El Niño, found that the 1982 and 1997 events led to $4.1 trillion and $5.7 trillion in lost income in the five years following them. With El Niño projected to return this year, the researchers project that global economic losses for the 21st century will amount to $84 trillion as climate change potentially amplifies the events' frequency and strength.
Published Climate change to push species over abrupt tipping points
(via sciencedaily.com) Original source Climate change is likely to abruptly push species over tipping points as their geographic ranges reach unforeseen temperatures, finds a new study.
Published Study finds carrying pollen heats up bumble bees, raises new climate change questions
(via sciencedaily.com) Original source A new study finds carrying pollen is a workout that significantly increases the body temperature of bumble bees. This new understanding of active bumble bee body temperatures raises questions about how these species will be impacted by a warmer world due to climate change.
Published Extremely hot days are warming twice as fast as average summer days in North-West Europe
(via sciencedaily.com) Original source New study analyzed data on near-surface air temperatures recorded for North-West Europe over the past 60 years. The findings show that the maximum temperature of the hottest days is increasing at twice the rate of the maximum temperature of average summer days. The results highlight the need for urgent action by policy makers to adapt essential infrastructure to the impacts of climate change.
Published We now know exactly what happens in nature when we fell forests
(via sciencedaily.com) Original source Deforestation is the biggest threat to the planet's ecosystems, and new research has now mapped out exactly what happens when agriculture replaces forestry.
