What Do You Know About New York Whales?
July 15, 2016 11:48 AM - Judy Molland, Care2
In case you thought wildlife in New York was pretty much limited to the squirrels and pigeons of Central Park, Howard Rosenbaum has news for you.
“In less distance out to sea than the average New Yorker’s commute home, there is likely a whale singing at this very moment,” says Rosenbaum, director of the Ocean Giants program at the New York Aquarium in Coney Island, Brooklyn.
7 Species Of Whales Spotted In New York Waters
Humpback whales (seen above) are regularly seen in the waters off the Big Apple, while fin whales inhabit the waters around the eastern tip of Long Island. Five other species, the critically endangered North Atlantic right whale and minke and sperm whales, as well as sei whales and the blue whale, the largest animal that has ever lived (seen below) have also been seen or heard in New York waters.
Why Are There Frogs With Extra Limbs and Missing Eyes in Australia?
July 15, 2016 10:32 AM - Jessica Ramos, Care2
There’s something strange happening in Queensland, Australia: the frog populations are dropping like flies and frog deformities are on the rise. One frog doctor (yes, that’s a legitimate thing) blames insecticides, particularly neonicotinoids. The problem is that no one from the academic community or government is taking these issues seriously.
Deborah Pergolotti runs the Cairns Frog Safe project — Australia’s only hospital that serves frog patients — and she’s witnessing disturbing trends. Pergolotti told the Guardian there has been a 95% decline in the Cairns frog population over the last 17 years. Coincidentally, neonicotinoids were first introduced in Australia in 1996 — just three years prior to the decline that Pergolotti cites.
At this point, Pergolotti can only speculate because no one has been looking into the toxicology. “If somebody would get around to doing the toxicology for it, then maybe we might get some proof, but nobody’s interested in the toxicology,” she tells the Guardian.
Black bear links real objects to computer images
July 14, 2016 10:43 AM - Springer via EurekAlert!
American black bears may be able to recognize things they know in real life, such as pieces of food or humans, when looking at a photograph of the same thing. This is one of the findings of a study led by Zoe Johnson-Ulrich and Jennifer Vonk of Oakland University in the US, which involved a black bear called Migwan and a computer screen. The findings are published in Springer's journal Animal Cognition.
The study forms part of a broader research project into the welfare of bears in captivity. It aims to find out how the animals themselves rate the environment in which they are held, and the facilities, food and features provided to them. The goal is to assess this by presenting bears with photographs of objects. To do so, the research team first had to assess whether bears are in fact able to recognize 2-D images of objects and people familiar to them when these are presented to them on a touch screen.
Rising sea levels will change the ecology of the Everglades
July 14, 2016 09:19 AM - CHRISTOPHER JOYCE, NPR
The Florida Everglades is a swampy wilderness the size of Delaware. In some places along the road in southern Florida, it looks like tall saw grass to the horizon, a prairie punctuated with a few twisted cypress trees. The sky is the palest blue.
But beneath the surface a different story is unfolding. Because of climate change and sea level rise, the ocean is starting to seep into the swampland. If the invasion grows worse, it could drastically change the Everglades, and a way of life for millions of residents in South Florida.
A Growing Crisis: Insects are Disappearing — And Fast
July 13, 2016 04:13 PM - Nithin Coca , Triple Pundit
We all know about the huge declines in bee and monarch butterfly populations. Now, it turns out that in some areas nearly all insects are at risk of extinction. And if we don’t solve this problem soon, the repercussions could be huge.
Insects are an important part of the global ecosystem. They not only provide important pollination services, but they also occupy an important place on the bottom of the food chain for many animals. Fewer insects means less food, leading to plant and animal population declines.
“The growing threat to [insects], which play an important role in food security, provides another compelling example of how connected people are to our environment, and how deeply entwined our fate is with that of the natural world,” said Achim Steiner, the executive director of the United Nations Environment Program, in a press statement.
Genetically improving sorghum for production of biofuel
July 13, 2016 03:15 PM - Genetics Society of America via EurekAlert!
The bioenergy crop sorghum holds great promise as a raw material for making environmentally friendly fuels and chemicals that offer alternatives to petroleum-based products. Sorghum can potentially yield more energy per area of land than other crops while requiring much less input in terms of fertilizer or chemicals. New research examines how genetic improvement of specific sorghum traits, with an eye toward sustainability, could help maximize the usefulness of sorghum as a bioenergy crop.
The work was conducted by researchers from the University of Florida in Gainesville, Washington State University in Pullman, the USDA-ARS in Lincoln, Nebraska, and the University of Missouri, Columbia. They highlight disease resistance, flooding tolerance and cell wall composition as key targets for genetically improving sorghum for sustainable production of renewable fuels and chemicals.
Alaska's shorebirds exposed to mercury
July 13, 2016 10:07 AM - Central Ornithology Publication Office via EurekAlert!
Shorebirds breeding in Alaska are being exposed to mercury at levels that could put their populations at risk, according to new research from The Condor: Ornithological Applications.
Thanks to atmospheric circulation and other factors, the mercury that we deposit into the environment tends to accumulate in the Arctic. Mercury exposure can reduce birds' reproductive success and sometimes even be lethal. Shorebirds may be particularly vulnerable because they forage in aquatic environments where mercury is converted into methylmercury, its most dangerous form. Marie Perkins of the Biodiversity Research Institute (BRI) and her colleagues investigated the level of mercury in Alaska's shorebirds and found that some birds breeding near Barrow, at the state's northern end, have mercury concentrations upwards of two micrograms per gram of blood.
Monkeys in Brazil have used stone tools for hundreds of years at least
July 11, 2016 01:10 PM - University of Oxford
New archaeological evidence suggests that Brazilian capuchins have been using stone tools to crack open cashew nuts for at least 700 years, and the new research paper asks whether human behaviour was influenced through watching the monkeys.
Researchers say, to date, they have found the earliest archaeological examples of monkey tool use outside of Africa. In their paper, published in Current Biology, they suggest it raises questions about the origins and spread of tool use in New World monkeys and, controversially perhaps, prompts us to look at whether early human behaviour was influenced by their observations of monkeys using stones as tools. The research was led by Dr Michael Haslam of the University of Oxford, who in previous papers presents archaeological evidence showing that wild macaques in coastal Thailand used stone tools for decades at least to open shellfish and nuts.
Horrible algae bloom in Florida blamed on the government
July 10, 2016 09:12 AM - Greg Allen/NPR
About a hundred miles north of Miami on the Atlantic Coast, the town of Stuart is a picturesque waterfront community — with homes, restaurants and parks overlooking the St. Lucie Estuary. But in many areas now, when you approach the water, the first thing you notice is the smell.
"There's no way to describe it," says John Skinner, a boat salesman in Stuart.
But he still tries. "I would say hundreds of dead animals that have been baking in the sun for weeks."
After decades of clean up attempts, world's lakes still suffer from phosphorus pollution
July 8, 2016 10:52 AM - University of Southern Denmark via EurekAlert!
Leading scientists warn: Phosphorus pollution is a major concern. We need to speed up recovery treatments of lakes - or accept poor freshwater quality. In a series of studies published in a special issue of the journal Water Research, leading scientists assess how to control phosphorus pollution in lakes.
- In 40 % of Europe's lakes the water quality does not meet the demands of EUs Water Framework Directive, mainly due to phosphorus pollution. That is a huge problem for biodiversity and society and we need to put an effort into developing effective approaches to restore these lakes, says Associate Professor Kasper Reitzel, Department of Biology, University of Southern Denmark.
Together with colleagues Sara Egemose and Henning S. Jensen, Reitzel is co-author of several contributions in a special issue of the journal Water Research. Kasper Reitzel is also co-editor. They are experts in lake restoration and are associated with the Villum Kann Rasmussen Centre of Excellence, Centre for Lake Restoration, (CLEAR).
