Honeybee Populations — Responsible for 90% of All Commercial Pollination — Continue to Disappear, Will Impact Humans
By Julia Rauchfuss – “Best known for prompting shrieks and swatting of air, bees rarely receive proper recognition for their contributions to humankind. But now that they are disappearing by the thousands, it will be up to humans to ensure their survival.
Over the past five years, about 30 percent of the yearly captive honeybee population has died every winter, according to CNN, and about 10 percent of bees simply vanish. While recent reports suggest that this may not cause significant damage to the U.S. agriculture industry due to better farming technologies, preservation of the species still deserves immediate attention.
Humans have always shared a close partnership with honeybees but if care is not taken soon human ignorance could twist this simple, symbiotic relationship into a form of parasitism. Bees are far more beneficial to humans than they are dangerous.
Honeybees are pollinators, and play a crucial role in the production of seeds, which are contained in the fruits, vegetables and grains that line grocery store shelves.
Though some crops such as wheat are pollinated by the wind, honeybees are responsible for the 90 percent of all commercial pollination, according to an article in Applied Microbiology and Biotechnology.
According to researchers, the shrinking honeybee population is the result of colony collapse disorder, the sudden and unexplained disappearance of all the worker bees in a hive. Agricultural insecticides are a prime suspect, as beekeeper accounts suggest certain insecticides negatively affect bees, according to an article in Issues in Science and Technology. However, the Environmental Protection Agency requires more scientific data to take products off the market.
The phenomenon also puts another population at risk.” Read more.

‘Fish Dying in Rivers’: Drought Declared in the South East of England, Water Restrictions Expected Within Weeks
By Matthew Holehouse – “Some reservoirs, rivers and groundwater aquifers in the South East well below normal levels after two dry winters.
The state of drought in the region was declared after the Environment Department (Defra) convened a summit of water companies, farmers and wildlife groups today to discuss potential water shortages in England.
Following the summit, Thames Water warned that there was a high chance of water restrictions such as hosepipe bans this summer, unless there was significant rainfall or customers used less water.
Some rivers and groundwater levels are lower than during the drought of 1976.
The RSPB is warning that if the drought situation continues, it could spell potential disaster for wildlife.
Birds, mammals and bugs could be struggling to survive into the summer if the rain doesn’t fall in the next few weeks as valuable wetlands dry up.
Charlie Kitchin, RSPB Site Manager for the area said: ‘The breeding season of 2011 was not good at all for this nature reserve. Winter flooding is essential to attract the large numbers of wild swans and other wildfowl that the washes are renowned for and this winter has been the quietest for many years, for example our wigeon numbers are down from 20,000 to 3,000.'” Read more.
Take an ‘egg timer’ into the shower say water companies – “Residents are being sent waterproof ‘egg timers’ so they don’t linger in the shower, in attempt to preserve dwindling waters stocks by reducing consumption. Caroline Spelman, the Environment Secretary, was forced to declare drought in the most populated area of Britain after two dry winters in a row left reservoirs dangerously low and fish dying in rivers. The Anglia region was already in drought, meaning more than half of the population of the UK faces hosepipe bans in a matter of weeks. There could even be restrictions in London – part of the South East region – where thousands of litres more water will be needed because of the Olympics.” Read more.
‘A Bleak Picture of the State of the World’s Oceans’: Animal Diseases, Parasites Increasingly Plague Sea Mammals
“VANCOUVER – When dead sea mammals started washing ashore on Canada’s west coast in greater numbers, marine biologist Andrew Trites was distressed to find that domestic animal diseases were killing them.
Around the world seals, otters and other species are increasingly infected by parasites and other diseases long common in goats, cows, cats and dogs, marine mammal experts told a major science conference.
The diseases also increasingly threaten people who use the oceans for recreation, work or a source of seafood, scientists told reporters at the annual meeting of the American Association for the Advancement of Science, held this year in this Western Canadian city.
The symposium ‘Swimming in Sick Seas’ was one of many sessions at this year’s AAAS that drew a bleak picture of the state of the world’s oceans, which are increasingly acidic, warming in some areas and being inundated with melting ice or other climate change effects.
‘There are dramatic shifts in the ocean ecosystem,’ said Jason Hall-Spencer of Britain’s University of Plymouth, citing his research in Italy, Baha California and Papua New Guinea that is ‘all showing the same thing’ …” Read more.
Necropsy Finds Large Number of Parasites ‘Channeling Into the Brain’ of Dolphin That Died in Ocean City – “Preliminary results of a necropsy performed on the dolphin found dead in a bayside Ocean City lagoon on Sunday (Feb. 12) show ‘a heavy load of parasites channeling into the brain,’ according to Bob Schoelkopf, the director of the Marine Mammal Stranding Center in Brigantine. Similar parasites were found in a dolphin found dead on a Delaware Bay beach in Lower Township on Sunday and in a dolphin that died shortly after stranding in Stafford Township off Barnegat Bay on Monday (Feb. 13), Schoelkopf said. All three animals were common dolphins, a species that typically travels in groups at least 20 miles off the coast of New Jersey.” Read more.
Radiation Ruled Out As Cause of Alaska Seal Deaths, For Now
Here’s an update on this story …
By Yereth Rosen – “ANCHORAGE, Alaska (Reuters) – Preliminary tests appear to rule out radiation from Japan’s tsunami-wrecked Fukushima nuclear power plant as the cause of mysterious deaths and illness that struck scores of Alaska seals last year, federal officials said on Friday.
Preliminary tests of tissue samples from animals that fell victim to the lesion-causing disease found that radiation levels were normal and within ‘the typical background range for Alaska,’ The National Oceanic and Atmospheric Administration said in a statement.
More than 60 dead and 75 sickened seals, most of them ringed seals, were found on the northern and western coasts of Alaska last summer and fall. Some walruses were also afflicted by the disease, with a smaller number found dead.
The affected animals have bleeding lesions on their flippers and other body parts, patchy loss of hair, labored breathing and lethargy, according to NOAA, which in December declared the problem an ‘unusual mortality event.’
The findings that appear to clear the Fukushima plant of blame are only preliminary, Juneau-based NOAA spokeswoman Julie Speegle said, and more analysis will be conducted. Tests on healthy animals also found normal levels of radiation.
‘Part of the reason it doesn’t rule it out is we need to do more in-depth tests for Cesium 137 and Cesium 134,’ Speegle said.” Read more.
‘A Scene Out Of An Alfred Hitchcock Movie’: Dead Birds Cause Mess On I-95 In Laurel, Maryland
“LAUREL, Md. (CBSDC) — A scene out of an Alfred Hitchcock movie played out in real life along Interstate 95 in Maryland on Wednesday.
About a hundred dead birds were scattered across a stretch of the highway in Laurel near exit 33, likely victims of an impact with a vehicle.
‘[European] Starlings are birds the fly around in pretty good size flocks,’ said David Hellmeyer of the Maryland Department of Natural Resources told All-News 99.1 WNEW.
Hellmeyer said it’s pretty uncommon, but not unheard of for that species to be struck by vehicles.
The mess caused heavy congestion just before the afternoon rush got underway around 3 p.m. Some drivers says the delays spanned miles.
State highway officials were able to respond and clean up the mess fairly quickly.
The birds have been collected for testing to confirm the trauma was the cause of death.” Source – CBSDC.
New Zealand: Up To 800 Birds Found Dead at Wetlands in Eastern Suburbs of Christchurch, Avian Botulism Suspected
“Up to 800 birds have been found dead at wetlands in Christchurch’s eastern suburbs and the oxidation ponds.
The Christchurch City Council said yesterday that during the past few weeks dead birds have been found on the banks of the oxidation ponds in Bromley.
Dead birds have also been found in the Bexley area and the Travis Wetland.
Council ornithologist Andrew Crossland said between 600 and 800 dead birds had been found.
‘The earthquakes in Christchurch have caused a lot of changes to water quality but also to effluent levels at the oxidation ponds,’ he said.
‘It’s got nothing to do with anything physical such as liquefaction but more to do with the fluctuating water levels and changes like that.’
Investigations were underway but the initial diagnosis was avian botulism, a paralysing disease caused by a toxin which thrives in shallow, warm water.” Source – The Press.
Peru: Over 200 Dolphins Found Dead Along 106 Kilometer Stretch of Lambayeque Beaches
By Manuel Vigo – “This week more than 200 dolphins were found dead along a 106-kilometer stretch at the beaches of Lambayeque.
Authorities have not yet been able to determine the cause of the deaths.
According to El Comercio, Edward Barriga, head of Peru’s Ocean Institute (Imarpe) in Lambayeque, ordered samples be sent to Lima, for further analysis.
‘Soon we will announce the root causes,’ Barriga said.
Barriga said he had also found considerable quantities of dead anchovies on the beaches between the district of San jose and Palo Parado, in Morrope.
Jorge Torres Cabrejos, head of the Lambayeque’s Association of Maritime Growers, said the dolphins might have eaten the dead anchovies, who had died from decomposing plankton, caused by heavy pollution.
According to El Comercio, Torres denied that local fisherman were to blame for the dolphins’ deaths.
Last month Imarpe investigated the death of several dolphins and sea lions in the beaches of Piura.
Local media said the deaths could have been the result of oil spills in the area.” Source – Peru This Week.
Massachusetts: Cape Cod Dolphin Beachings Rise to 129 with 92 Deaths, More Expected in Largest Mass Stranding in MA’s Recorded History
Here’s an update on this story, with no end in sight …
By Miguel Llanos – “More strandings are expected after 129 dolphins beached themselves on Cape Cod in the last three weeks, with 92 dying in ‘the single largest stranding’ of dolphins in the Northeast since at least 1999, the International Fund for Animal Welfare reported Monday.
On Sunday, four dolphins were stranded along Cape Cod’s hook-shaped peninsula and were quickly helped back to sea. The Massachusetts peninsula sees many dolphin strandings each year, but the 129 since Jan. 12 is typically about what rescuers see over an entire year, based on records that go back to 1999, IFAW marine mammal rescue manager Katie Moore told msnbc.com.
‘This event started on the 12th and is still continuing,’ she added at a press conference on Monday, noting that rescuers from IFAW and other stranding networks were deployed in ‘anticipation of more dolphins coming in.’
The National Oceanic and Atmospheric Administration, which manages the rescue response, echoed the concern.
For common dolphins, the species that has been stranding in Cape Cod, ‘this is the largest, most protracted stranding event in recent decades,’ Teri Rowles, who coordinates NOAA’s Marine Mammal Health and Stranding Response Program, told msnbc.com.
Most of the dolphins have appeared to be in good health, adding to the mystery of why so many have come ashore. Common dolphins are known to strand in groups due to their tight social structure, but given the large numbers this year, other factors such as weather and tides are being investigated.” Read more.
South Dakota: Game Agency Investigates Mysterious Deaths of 100 Pigeons in Downtown Rapid City
RAPID CITY, S.D. (AP) – The South Dakota Game, Fish & Parks Department is investigating about 100 suspicious deaths in downtown Rapid City – and the victims are all pigeons.
John Kanta, regional wildlife manager for the department, tells the Associated Press that dozens of bird corpses have been recovered since Thursday afternoon. The deaths are mysterious enough that samples have been flown to a lab in Madison, Wis., in hopes of determining the cause.
Kanta says the birds could have been sickened by mold or bacteria, but officials suspect they were poisoned.
Kanta says officials are ‘worried about the incidental loss we might see with other animals’ – specifically peregrine falcons.” Read more.
Virginia: More Than 1,000 Fish Found Dead in Henrico County, ‘Everything is Wiped Out’
“HENRICO, VA (WWBT) – State authorities are looking into why more than a thousand fish turned up dead in Henrico County. It happened in the Winchester Green subdivision, in the far west end.
It is quite the unpleasant sight, a fish kill, neighbors first discovered earlier in the week. Authorities came out to take a look, and they say more than 1,000 fish died here earlier in the week.
It’s a mystery, and it’s not pretty: all these dead fish, scattered over two ponds in an otherwise picturesque community.
Sandra register has lived here 22 years and she’s never seen anything like it.
‘We’ve never had everything die. I mean, everything is wiped out in here,’ she said.
The floating and decaying remains were first discovered Monday; including that of a large beaver, though it’s unclear if that’s related. All week, Sandra and others have been speculating as to what might have happened.
‘That someone had put something in the water,’ Sandra said.
Officials with the Department of Environmental Quality won’t confirm that. In fact, there’s little they can say for sure.
What’s clear is that it’s so upsetting to the children and adults who take great pride in what they used to be able to see, right outside their windows.
‘It’s important to me. I sit at my kitchen table and drink my coffee and watch the deer and occasionally get a glimpse of the fox running by. It’s very important to me,’ Sandra stated.
Whatever happened here to cause this, isn’t quite clear. But the DEQ continues to investigate. They say there is no risk to the public.
Neighbors say the water has yet to be tested, but there doesn’t appear to be any evidence of a chemical spill or illegal dumping.” Source – Fox19.
California: Moss Landing Residents ‘Alarmed by the Sheer Number’ of Bird Deaths on Local Beach, ‘Something in the Water’ Killed Them
By Rachel Ramirez – “Moss Landing, Calif. -Sea shells and crabs are usually found along the shore, but in Moss Landing people say a different animal is stinking up the beach.
‘Last week, [There was] clear beach, clear skies, beautiful weather. Now what do I see? There are carcasses on the beach. Why?’ said Michael Kasclica, who lives in Watsonville and walks frequently at Moss Landing Harbor beach.
At the edge of Sandholdt Road in Moss Landing is a graveyard for a variety of rotting birds.
‘It’s despicable and it is definitely unusual,’ said Kasclica.
People walking along the beach said they found a half dozen birds on both sides of the beach and are alarmed by the sheer number and variety of dead birds.
Both the California Department of Fish and Game and the SPCA Wildlife Center came to check out the dead birds. The departments don’t know what killed them and called the scene out of the ordinary.
‘The concern is the amount of birds and the location where they’re at. It’s hard for them to wash a shore this high up,’ said Warden Sarah Weimer of the California Department of Fish and Game.
‘There are a lot of them. A necropsy will show if there are any gun wounds or any human infliction of injury. But otherwise, it looks like something else is going on,’ said Jessica Shipman, the interim SPCA Wildlife Center supervisor.
SPCA interim Wildlife supervisor said it seems something in the water killed the birds.
‘The fish eat the toxic algae and the birds eat the contaminated fish. Their bodies can’t handle that,’ said Shipman.
Most of the dozen birds were taken to biologists at the Department of Fish and Game in Monterey to be tested. The Department of Fish and Game said test results will show the cause of death. Experts do not suspect any human foul play.” Source – Central Coast NEWS.
Australia: ‘Black Water Event’ Kills Hundreds of Fish in Melbourne Reservoir Wetlands
“A popular wetland in Melbourne’s north has been hit by a ‘black water’ event that has killed hundreds of fish.
A POPULAR wetland in Melbourne’s north has been hit by a ‘black water’ event that has killed hundreds of fish.
Local residents described the water just north of Edwardes Lake in Reservoir as jet black and smelling rotten.
The black water in the Edgars Creek wetlands has again highlighted problems with the health of Melbourne’s waterways, which have been plagued by stormwater runoff and sewage spills after heavy rain.
The Environment Protection Agency says it is still investigating the cause of the black water. Spokeswoman Tanya O’Shea said officers initially observed 30 dead carp – an invasive pest – the largest being 45 centimetres long.
Darebin Council city design and environment director Daniel Freer said 200 to 300 carp had perished in the black water, along with a few smaller fish, likely to be perch.
The EPA says it has instructed the council to clean the dead fish from the wetlands, which have now been partly drained and will be flushed with fresh water.
Black water events – when oxygen is dissolved from the water – are usually caused by dry, hot weather or an abundance of organic matter like leaves being built up or swept into a waterway after rain. Last summer a black water event hit the Murray River, killing hundreds of Murray cod.
But local conservationists are concerned sewage run-off may have played a role in the black water event. Luisa Macmillan, manager of the Merri Creek Management Committee, said there have been previous overflows of sewage into Edgars Creek, and it was an imperative the event be investigated.” Source – Optus Zoo.
