Comments Off on New study finds glyphosate in kids’ cereals and snack bars

Bad news for anyone who likes to eat cereal, or granola bars, or anything that contains oats at all: a recent study by the Environmental Working Group (EWG) tested 45 conventional oat products for the presence of glyphosate, and researchers found it in 43 of them.  And, of these 43 oat products, 31 had amounts of glyphosate that were far above the EWG’s Health Benchmark of safe ingestion amounts. The poisonous chemical may sound familiar since it’s the active ingredient in Roundup, the herbicide whose health risks Monsanto intentionally concealed from the public. Related: Court orders Monsanto to pay $289 million in cancer trial The World Health Organization has issued warnings about glyphosate in the past, stating as far back as 2015 that glyphosate is “probably carcinogenic to humans.” And yet, the majority of oat products tested for the study had glyphosate levels that exceeded 160 ppb, the maximum amount considered acceptable by the EWG. In fact, one popular brand of oats contained 1300 ppb. While organic oats did much better, 30 percent of samples using organic oats still tested positive for glyphosate, possibly due to Roundup drift from farms in the area or cross-contamination.

No one wants to eat a weed killer for breakfast, and no one should have to do so,” commented Ken Cook, President of the EWG.  Calling for action on our part, he added, “it’s up to consumers to call on companies to rid their products of glyphosate.” + Environmental Working Group Via Treehugger

Comments Off on Canada moves to ban bee-killing pesticides

Environmentalists scored a victory in Canada on Wednesday, securing restrictions on two pesticides that have been posing threats to bees and aquatic insects. The Canadian government’s Pest Management Regulatory Agency (PMRA), branched under the division ‘Health Canada,’ has agreed to impose constraints on the crop chemicals, slowly phasing out their use over the next three to five years. Thiamethoxam, produced by Syngenta AG, and Bayer AG’s clothianidin are common farming applicants to protect crops such as corn, soybeans and canola from damage caused by insects. Thiamethoxam and clothianidin fall under a category of pesticides known as neonicotinoids, or neonics. Reports examining the link between honey bees and neonics in North America have been emerging over the past years in an attempt to explain declining bee populations. A recent review also found bodies of water contaminated with these pesticides can harm aquatic insects. Food chains within the environments are being affected by the infected insects, which are food sources for fish and birds . Related: EU approves complete ban on bee-killing insecticides “I’m thankful we’re going to see a phase-out,” said Jim Coneybeare, president of the Ontario Beekeepers Association . “I’d like it to happen sooner.” According to the association, the overwhelming use of neonics has been disastrous for bee colonies in Ontario. The survival of bee habitats is already precarious; only a little more than half were able to survive the most recent winter season alone. Farmers, on the other hand, are given few alternatives to sustain consumer demands and not have their stocks fall to pestilence. Barry Senft, CEO of Grain Farmers of Ontario, said neonics are an “important tool” in farming. Many farmers, and some beekeepers, also worry that the regulation will prompt the use of even harsher chemicals , because the development of successful eco-friendly alternatives has been slow. Related: Beekeepers file a complaint against Bayer after glyphosate was discovered in honey A third compound, imidacloprid, also produced by Bayer, will come under scrutiny in Canada by the end of the year. The EU banned the outdoor use of neonics in April, and the pesticides are undergoing scientific review in the U.S. before proposed action opens to public commentary next spring. Ultimately, the pesticide ban in Canada will face a 90-day consultation period, and the verdict will not be finalized until late 2019. Via Reuters Image via Aleksandar Cocek

About 90% of world’s largest king penguin colony has mysteriously disappeared

Comments Off on About 90% of world’s largest king penguin colony has mysteriously disappeared

Recent satellite images and a new study show that only 200,000 of the two million king penguins who lived on the French island of Île aux Cochons in 1982 still remain. The drastic disappearance of these penguins is a puzzling occurrence that scientists are still trying to piece together, but they are looking at climate change as the likely culprit. The remote Île aux Cochons lies halfway between the tip of Africa and Antarctica and is home to the largest colony of king penguins in the world. Henri Weimerskirch, ecologist at the Centre for Biological Studies in Chize, France , first witnessed this colony in the early 1980s and plans to return to the island in early 2019 after three decades of satellite images revealed the population collapse. “It is completely unexpected, and particularly significant since this colony represented nearly one third of the king penguins in the world,” Weimerskirch said. Related: The world’s largest wildlife sanctuary proposed for Antarctica The IUCN Red List of Threatened Species is still listing the conservation effort for these creatures under the “least concern” status despite the recent decline in numbers. As for what happened to hundreds of thousands of mated pairs of king penguins, there are several possibilities that Weimerskirch and his colleagues are juggling. The most likely causes are climate change and resulting El Niño weather events, competition for food and avian cholera. Scientists have not been able to examine the penguins for indications leading to a singular cause, but chances are that the factors are intermingled and aggravated by each other. Competition, which can be worsened by climate change, leads to a lack of food, resulting in struggles that are “amplified and can trigger an unprecedented rapid and drastic drop in numbers,” according to Weimerskirch. Another possible factor in the penguins’ decline could be an incident similar to the El Niño event that decimated the Emperor penguin population in Terre Adélie by 50 percent in the late 1970s. Meanwhile, avian cholera has impacted birds on nearby islands, and could be the problem on Île aux Cochons. The news is particularly daunting for the king penguins, because they only lay one egg at a time when nesting. The penguins carry the egg around on their feet, and the mates take turns every few weeks protecting and incubating the chick until it is hatched. This process takes over two months. Because the penguins do not nest year-round, and with food becoming scarcer and scarcer, a rapid rebound in population does not seem likely. + Antarctic Science Via The Guardian,   IUCN and Cool Antarctica Image via Liam Quinn

Arctic shipping routes could threaten "unicorns of the sea"

Comments Off on Arctic shipping routes could threaten "unicorns of the sea"

Narwhals, or the “unicorns of the sea,” could be at risk from additional Arctic shipping routes as polar ice continues to recede. A peer-reviewed study published in Proceedings of the National Academy of Sciences suggests as many as seven marine mammal species may face new threats and uncertain consequences from increased ship traffic. The Arctic Ocean is home to hundreds of animals, like narwhals, polar bears and whales. However, as the polar ice caps retreat, more shipping companies are taking advantage of open waters to reduce travel time. To determine how the increase of ships could affect marine mammals , the research team from University of Alaska Fairbanks and University of Washington studied wildlife during the fall shipping season. The group looked at 80 different subpopulations among the seven species to determine if they were directly exposed to the ships and how much these ships could affect the wellbeing of the marine life. Related: The melting Arctic is already changing the ocean’s circulation During the study period, over half of the subpopulations were impacted by ships, with narwhals inheriting the highest amount of risk. In addition to an increased risk of injury or death from collisions,  toothed whales also face communication challenges because of their audio sensitivity. Like dolphins, the ocean unicorn “talks” with a language of buzzing, clicking and calling. While narwhals could have the most to lose, polar bears and seals have the least risk because of the time they spend on land. But researchers note their populations also come with high long-term uncertainty, and the team concluded more data is required to determine how shipping affects their livelihood. The news wasn’t entirely bad for wildlife populations. The scientists noted through additional data collection, shipping companies could plan for environmentally-sustainable transportation options. “Regions with geographic bottlenecks, such as the Bering Strait and eastern Canadian Arctic, were characterized by two to three times higher vulnerability than more remote regions,” the researchers wrote in their study abstract. “These pinch points are obligatory pathways for both vessels and migratory [ocean mammals], and so represent potentially high conflict areas but also opportunities for conservation-informed planning .” Arctic planning groups are aware of the wildlife threats and are working out plans to balance shipping with environmental concerns. The Arctic Council instituted regulations on transport companies in January 2017, with the goal of making shipping safer for both crews and marine mammals. + Proceedings of the National Academy of Sciences Via Earther

Scientists discover new gibbon species inside tomb of Chinese emperor’s grandmother

Comments Off on Scientists discover new gibbon species inside tomb of Chinese emperor’s grandmother

In a new study published in the journal Science , scientists detail the identification of a new species of gibbon, one that had gone extinct at some point over the past two millennia. The remains of Junzi imperialis were first discovered in 2004, when archaeologists at Shaanxi Provincial Institute of Archaeology in Xi’an discovered a mausoleum nearby the tomb of Qin Shi Huang, China ‘s first emperor, which is famously guarded by thousands of terracotta soldiers. In addition to the partial skull of the gibbon, the mausoleum contained bones from numerous animals, such as panthers, lynxes, black bears and cranes. The gibbon likely would have belonged to the emperor’s grandmother, Lady Xia. “Having gibbons as pets appears to have been common among Chinese royals during ancient times,” study co-author Alejandra Ortiz told NPR . Years after the gibbon skull was uncovered, London -based archaeologist Samuel Turvey took an interest in its unusual characteristics. The remains were discovered “a huge distance from any of China’s surviving gibbon populations,” hundreds of miles south of the tomb, Turvey told NPR , “which immediately suggested that this specimen could be something extremely interesting.” Research suggests that through deforestation, humans were the likely cause of the gibbon’s extinction. Because of the gibbon’s dependence on the tree canopy ecosystem, it is very vulnerable to the destruction of its forest habitat. Related: Reforestation in China heralds the return of rare animals The discovery of a new, but extinct, ape species brings mixed emotions. “We feel that the discovery of Junzi imperialis is extremely important because it helps us to fill gaps in the understanding of gibbon diversity,” Ortiz said. However, the “discovery is sad, because it reinforces the idea that humans represent a major threat for the survival of species of gibbons and other apes, and our findings suggest that we have been a threat for quite a while.” + Science Via NPR Images via Benjamin Radzun and Eric Kilby

Giant manta ray nursery discovered in Gulf of Mexico

Comments Off on Giant manta ray nursery discovered in Gulf of Mexico

Researchers have identified the first recognized giant manta ray nursery in the Flower Garden Banks National Marine Sanctuary in the Gulf of Mexico , about 70 miles offshore from Galveston, Texas . Graduate student and executive director of  Manta Trust Josh Stewart first made this discovery while studying adult mantas in the area for the first time. “I was there trying to get a genetic sample from a full grown manta, and that’s when I saw it. It was a juvenile male manta, which is a very rare,” Stewart told NPR . After expressing his excitement to local researchers, he was informed that young manta sightings were quite common there. He said, “And that’s when I knew that this was a really special, unique place.” The local researchers at the National Oceanic Atmospheric Administration had misidentified the young manta rays as another species, neglecting to recognize the importance of this place until the arrival of an outside perspective. Typically, adult manta rays live in deep tropical and subtropical waters, making the study of these majestic sea creatures quite difficult. Young manta rays are almost never seen with adults. Related: Microplastic pollution poses particular threat to filter-feeding rays, sharks and whales “The juvenile life stage for oceanic mantas has been a bit of a black box for us, since we’re so rarely able to observe them,” Stewart explained. “We don’t know much about their movements, their feeding behavior and how that compares to the adults. Now we have a pool of juveniles that we can study.” The recognition of the nursery will ensure that these young mantas, now an endangered species in the U.S., are protected while also providing a road map for the protection of juvenile habitats around the world. “This research backs up the need for protection of other critical habitat, especially since manta rays have recently been designated as threatened species,” study co-author Michelle Johnston told the Herald Sun . “Threatened species need a safe space to grow up and thrive and live.” + Scripps Institution of Oceanography Via NPR and  The Herald Sun Images via G.P.

West Antarctica’s bedrock is rising, providing some protection to melting ice

Comments Off on West Antarctica’s bedrock is rising, providing some protection to melting ice

It seems that most news concerning Antarctica’s ice sheets is bad news, with two of the world’s fastest melting glaciers shrinking away in the continent’s western region. Fortunately, this same region is also home to an unusual geological feature that may provide some relief to the effects of climate change. In a new study published in the journal Science , researchers examined how the Earth’s surface seems to expand when heavy objects, such as glaciers , are no longer present and pushing down on the ground. According to data gathered from GPS sensors, the land beneath the Amundsen Sea Embayment in western Antarctica is rising at a rate of about two inches per year, one of the fastest rising rates ever recorded. As is often the case, the discovery of western Antarctica’s rising bedrock was made somewhat by chance. “[Study co-author] Terry Wilson and colleagues were extremely wise and lucky,” study co-author Valentina Barletta told Earther . “They had the really, really good idea [to place those sensors] with very few indication[s] that there might have been something special.” The researchers concluded that the land beneath the Amundsen Sea Embayment springs back because of a relatively fluid mantle beneath the surface, which is more capable of responding to changes above. Related: Scientists uncover giant canyons under the ice in Antarctica “This study shows this region of Antarctica has a very short memory,” Antarctica researcher Matt King told Earther, likening the local geological phenomenon to memory foam. Understanding the impact that rebounding land can have enables researchers to more accurately assess ice loss, the measurement of which has been incomplete due to a lack of knowledge about rising rock. The study also provides some hope to those who live in coastal areas, which may benefit from the potential slowing of melting ice by its rising higher than the warmer water .

Comments Off on Animals are becoming nocturnal to avoid humans

Researchers have learned that dozens of species of animals have reacted to increased contact with human beings by shifting their internal clocks to become more nocturnal. “It suggests that animals might be playing it safe around people,” study leader Kaitlyn Gaynor told Phys.org . “We may think that we leave no trace when we’re just hiking in the woods , but our mere presence can have lasting consequences.” In a new study published in the journal Science , Gaynor and her team analyzed data from 76 previous studies on 62 different animal species spread out over six continents and concluded that even relatively low-impact activities can affect animal behavior. Animals featured in this study, many of whom were mammals, include coyotes in California, wild boars in Poland, lions in Tanzania, tigers in Nepal, and otters in Brazil . To determine the effect of human behavior on sleeping patterns, researchers determined how long animals were active at night when affected by different kinds of human activities, such as hunting, hiking , and farming. The team concluded that human presence correlated with a 20 percent increase on average of nocturnal activity among the animals studied. Related: Dutch town helps out rare bat species by installing “bat-friendly” streetlights This research is among the first to explore and quantify how human behavior impacts animal activity and sleep patterns on a broad scale.  “No one else has compiled all this information and analyzed it in such a … robust way,” researcher Ana Benitez Lopez, who reviewed the study, told Phys.org. The study is a reminder that simply being in a wild space can fundamentally change it. “It’s a little bit scary,” ecologist Marlee Tucker, who did not participate in the study, told Phys.org. “Even if people think that we’re not deliberately trying to impact animals, we probably are without knowing it.” While some animals will struggle with adapting to night life, the shift may also provide benefits to animals who hope to share space with humans without ever dealing with them. Armed with new knowledge, I will nonetheless continue to hike and camp , because it helps me sleep. Via Phys.org Images via Depositphotos

Comments Off on New study shows some LED lights can harm wildlife

Researchers have concluded that certain types of LED lights can be harmful toward a wide variety of wildlife, calling attention to the potential hazards of the rapid expansion of LED light usage. Though LEDs made up only 9 percent of the global market in 2011, that number is expected to rise to 69 percent by 2020. In a study published in the Journal of Experimental Zoology Part A: Ecological and Integrative Physiology , researchers concluded that blue and white LED lighting is the most harmful to wildlife , particularly animals such as sea turtles and insects, while green, amber and yellow are more favorable. As the urbanization of our planet continues, it is essential that policymakers and scientists understand the potential outcomes of altering a space so drastically from its natural state. “Outdoor environments are changing rapidly and in ways that can impact wildlife species,” study leader author Travis Longcore told Phys.org . The researchers incorporated existing ecological data into the study as the team examined the impacts of different kinds of LED lights on animals such as insects, sea turtles, salmon and Newell’s shearwater seabird. Related: New research links LED streetlights to increased risk of cancer LED lights seem to adversely affect species in different ways. Loggerhead sea turtle hatchlings can be lured inland by artificial light rather than into the ocean , while migrating juvenile salmon’s attraction to light may leave them vulnerable to predators. To better inform the public regarding the risks of LED, the study includes the first publicly available database that documents how about 24 different kinds of light can impact wildlife. “If we don’t provide advice and information to decision-makers, they will go with the cheapest lighting or lighting that serves only one interest and does not balance other interests,” Longcore said. “We provide a method to assess the probable consequences of new light sources to keep up with the changing technology and wildlife concerns.” + Journal of Experimental Zoology Via Phys.org Images via Depositphotos (1, 2)

Some of the oldest and largest baobab trees are dying

Comments Off on Some of the oldest and largest baobab trees are dying

A new survey of baobab trees throughout southern Africa has shown that most of the two dozen largest and oldest trees in the region have died in the past decade or are currently very ill. While human-caused physical damage to individual trees may explain specific die-offs, researchers believe that climate change, which is occurring faster in southern Africa than many places on Earth, may be the most significant factor in the trees’ poor health. “Such a disastrous decline is very unexpected,” chemist and survey organizer Adrian Patrut told NPR . “It’s a strange feeling, because these are trees which may live for 2,000 years or more, and we see that they’re dying one after another during our lifetime. It’s statistically very unlikely.” The iconic baobab are culturally important for many communities. A common myth explains the baobab’s unique shape as a result of gods punishing the tree for its vanity in its extraordinary size, with the baobab being uprooted and flipped upside down with its “roots” facing upwards. Baobabs can be cultivated for their nutritious leaves and fruit and may prove to be a source of economic development . The trees are also ecologically significant, providing habitat and food for a wide variety of mammals, birds, insects and reptiles. Related: Can this tree provide financial security for 10 million people in Africa? Because of their unique shape and growth patterns that distort their tree rings, accurate dating of a baobab is difficult. Despite some questioning of Patrut’s methods, researchers nonetheless recognize that baobab die-offs is an unsettling trend that deserves more study. As southern Africa likely faces intense temperature increases and drought , the urgency to understand and better protect the baobabs is clear. “The decline and death of so many large baobabs in recent years is so tragic,” ecologist David Baum told NPR . “It is heartbreaking that any should die — but even worse that we might be seeing the beginning of the end of all the giant baobabs on the planet.” Via NPR Images via Depositphotos (1, 2)
