Hidden chemical pathway could keep phosphorus from fueling lake algal blooms

Why do some lakes remain plagued by harmful algal blooms even after phosphorus pollution has been reduced? Part of the answer lies beneath the surface. A new Concordia study has uncovered a previously overlooked chemical process that can help trap phosphorus in lake sediments, preventing it from returning to the water, where it can fuel excessive plant and algal growth.

Life on the East Asian Flyway - Part 4: The Arctic

After flying thousands of kilometres from faraway Bangladesh and New Zealand via the Yellow Sea, the shorebirds of the East Asian Flyway complete their northward migration. They touch down in the Arctic Russia and Alaska to breed. In May and June, birds such as the endangered spoon-billed sandpiper and red knot fill the air of the Russian tundras with their mating calls and display flights. But why travel so far to raise the next generation? Presenter Ann Jones also discovers why Russian and British conservationists are taking eggs from the nests of the spoon-billed sandpiper, the most endangered shorebirds in the world, in a last ditch effort to save the species from extinction.Finally, with the mating season finished and a new generation ready to migrate for the first time, we follow the incredible non-stop flight of nine days by the bar-tailed godwit, as it migrates south from Alaska all the way to New Zealand. The record-breaking species is helped by somehow being able to sense the weather patterns across the entire Pacific Ocean.The series is a co-production from the BBC World Service and Australian ABC Radio National. The sound recordings from Russia and Alaska were provided by the Macaulay Library of Natural Sounds at the Cornell Lab of Ornithology.(Photo: Spoon-billed sandpiper chick in Chukotka, NE Russia.

Life on the East Asian Flyway

One of the great wonders of the natural world is in deep trouble.Millions of shorebirds fly from Australia and Southeast Asia to the Arctic every year. They follow the planet’s most gruelling migratory route – the East Asian Australasian Flyway. Join Ann Jones as she watches wading birds such as curlews, godwits and sandpipers prepare for their epic journey. They fatten up on clams to the point of obesity, to fuel the flight. They grow bigger hearts and flight muscles. Just before departure, they shrink their digestive organs to become the most efficient flying machines for their first 7 day non-stop flight. The birds’ lives are full of danger and the most serious threats are man-made. The flyway is in peril with many species plummeting towards extinction. As you’ll hear, it’s enough to make a grown man cry.The series is a co-production from the BBC World Service and Australian ABC Radio National.Image: Waders readying to migrate north at Roebuck Bay, Western Australia, Copyright: Ann Jones

The Neglected Sense

We may fear going blind, deaf or dumb, but few of us worry about losing our olfactory senses. And yet more than 200,000 people in the UK are anosmic - they cannot smell.Kathy Clugston is anosmic and gives a first hand account of the condition.She sets out on a personal mission to discover why she cannot smell. She has never before researched the extent to which smell guides and shapes our lives, how we smell and what parts of the brain are affected. For example, is her 'terrible memory' connected to the condition? Referred to by the experts as the forgotten or neglected sense, we reveal the seriousness of not being able to smell. Anosmia can be caused by a virus or a head injury, allergies, polyps, or a brain tumour, but for many, including Kathy, it is something that is missing from birth. Sanguine as she is, Kathy knows she is vulnerable - “I’ve left the gas on, fallen asleep with a pot on the stove”. She adds, "As I got older I began to realise how much I miss out on. People say "Oh, you can't smell B.O.! Lucky you!" but then it dawns on them that I can't smell freshly brewed coffee, newly cut grass, a baby's head, my partner's hair, a rose. I can't catch a whiff of something and be instantly transported back to my grandma's kitchen or an exotic holiday. It's as if life has a missing layer."(Photo: A nose)
