Published Choose where to plant energy crops wisely to minimise loss of biodiversity (via sciencedaily.com) Original source
In the fight to protect biodiversity and limit climate change, the world will reap what it sows.
Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread (via sciencedaily.com) Original source
Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published Ecologists reconstruct the history of biodiversity in the Indo-Australian archipelago and its rise as a hotspot (via sciencedaily.com) Original source
The Coral Triangle, also known as the Indo-Australian Archipelago, is renowned for having the greatest marine biodiversity on our planet. Despite its importance, the detailed evolutionary history of this biodiversity hotspot has remained largely a mystery. An international research team has now shed light on this history, reconstructing how biodiversity in the region has developed over the past 40 million years.
Published Climate change to shift tropical rains northward (via sciencedaily.com) Original source
Atmospheric scientists predict that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator. The northward rain shift would be spurred by carbon emissions that influence the formation of the intertropical convergence zones that are essentially atmospheric engines that drive about a third of the world's precipitation.
Published Projected loss of brown macroalgae and seagrasses with global environmental change (via sciencedaily.com) Original source
Researchers predict that climate change will drive a substantial redistribution of brown seaweeds and seagrasses at the global scale. The projected changes are alarming due to the fundamental role seaweeds and seagrasses in coastal ecosystems and provide evidence of the pervasive impacts of climate change on marine life.
Published Ammonites' fate sealed by meteor strike that wiped out dinosaurs (via sciencedaily.com) Original source
Ammonites were not in decline before their extinction, scientists have found.
Published Invasive ants spread by hitchhiking on everyday vehicles (via sciencedaily.com) Original source
Ants might spread to new locations by stowing away on everyday vehicles. Previously, this was thought to occur mostly on agricultural equipment.
Published Why the harsh Snowball Earth kick-started our earliest multicellular ancestors (via sciencedaily.com) Original source
Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions -- especially ocean viscosity and resource deprivation -- during the global glaciation period known as Snowball Earth could have driven eukaryotes to turn multicellular.
Published Ocean's loss of oxygen caused massive Jurassic extinction: Could it happen again? (via sciencedaily.com) Original source
Researchers have found a chemical clue in Italian limestone that explains a mass extinction of marine life in the Early Jurassic period, 183 million years ago. Volcanic activity pumped out CO2, warming oceans and lowering their oxygen levels. The findings may foretell the impact climate change and oxygen depletion might have on today's oceans.
Published Plankton researchers urge their colleagues to mix it up (via sciencedaily.com) Original source
A new article encourages researchers to focus their attention on mixoplankton, providing a set of methodologies to help expand our understanding of this critically important component of the marine ecosystem.
Published Frog 'saunas' a lifeline for endangered frog populations (via sciencedaily.com) Original source
New biologist-designed shelters will help endangered frogs survive the devastating impacts of a deadly fungal disease by regulating their body temperature to fight off infections.
Published Non-stop flight: 4,200 km transatlantic flight of the Painted Lady butterfly mapped (via sciencedaily.com) Original source
In October 2013 a researcher made a surprising discovery of Painted Lady Butterflies on the Atlantic beaches of French Guiana -- a species not typically found in South America. This unusual sighting prompted an international study to investigate the origin of these butterflies.
Published Fuel treatments reduce future wildfire severity (via sciencedaily.com) Original source
There is a common belief that prescribed burning, thinning trees, and clearing underbrush reduce risks of the severity of future fires. But is that true? A new project analyzing 40 studies where wildfire burned into different vegetation treatments, spanning 11 western states. Researchers found overwhelming evidence that in seasonally dry mixed conifer forests in the western U.S., reducing surface and ladder fuels and tree density through thinning, coupled with prescribed burning or pile burning, could reduce future wildfire severity by more than 60% relative to untreated areas.
Published New tomato, potato family tree shows that fruit color and size evolved together (via sciencedaily.com) Original source
A new family tree of the plant genus Solanum helps explain the striking diversity of their fruit color and size. This genus includes tomatoes, potatoes, eggplants, and other economically important plants.
Published Boosting biodiversity without hurting local economies (via sciencedaily.com) Original source
Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.
Published Wild chimpanzees seek out medicinal plants to treat illness and injuries (via sciencedaily.com) Original source
Chimpanzees appear to consume plants with medicinal properties to treat their ailments, according to a new study.
Published Newly discovered dinosaur boasts big, blade-like horns (via sciencedaily.com) Original source
A new dinosaur has been identified and named. The dinosaur's name, Lokiceratops rangiformis, translates roughly to 'Loki's horned face that looks like a caribou.'
Published Climate models underestimate carbon cycling through plants (via sciencedaily.com) Original source
The carbon stored globally by plants is shorter-lived and more vulnerable to climate change than previously thought, according to a new study.
Published Hurricane changed 'rules of the game' in monkey society (via sciencedaily.com) Original source
A devastating hurricane transformed a monkey society by changing the pros and cons of interacting with others, new research shows.
Published Non-native plants and animals expanding ranges 100 times faster than native species (via sciencedaily.com) Original source
An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.
