AMHERST, Mass – A new study of songbird dehydration and survival risk during heat waves in the United States desert Southwest suggests that some birds are at risk of lethal dehydration and mass die-offs when water is scarce, and the risk is expected to increase as climate change advances.  

A University of Wyoming researcher is part of an international team that has discovered how more than 700 species of fish have evolved in East Africa’s Lake Victoria region over the past 150,000 years.

Building the wall that Donald Trump has ordered on January 25th, as one of his first actions as US president, will put on risk more than 50 animal species that share the ecosystem along the border between the United States and Mexico, scientists from various countries have warned.
 
Since 2006, 1,100 kilometers of barriers covering more than 30 per cent of the border between the countries have been built. The newest executive order commands the “immediate construction of a physical wall”, stating that ‘wall’ means “a physical barrier, continuous and impassable”.

Humans aren’t the only species that resort to a little subterfuge

While a dominant male fish from northern Mexico mates with a female, a small fella bides his time in the offing. Suddenly, the little guy darts in ahead of Mr. Big and plants his seeds on freshly laid eggs.

York University biologist and bee expert, Professor Amro Zayed, continues to produce and publish original research of global importance. This time, he has contributed a news and views article in Nature (November 2016) that puts into context the work of an Australian researcher who discovered how natural selection allows an invader bee population to overcome the genetic odds stacked against it. The study, led by Professor Rosalyn Gloag of the University of Sydney, New South Wales, examined the invasion of Asian honeybees over an eight-year time frame.

LED street lighting can be tailored to reduce its impacts on the environment, according to new research by the University of Exeter.

The UK-based study found predatory spiders and beetles were drawn to grassland patches lit by LED lighting at night, but the number of species affected was markedly reduced when the lights were dimmed by 50% and switched off between midnight and 4am.

A report published in the journal Biological Conservation finds that recent increases in human pressure and forest loss are causing the degradation of over 100 Natural World Heritage Sites (NWHS) globally.

China leads the world in greenhouse gas emissions. Its biggest cities are shrouded in smog. And the country’s population is 1.4 billion people and growing. At least to the rest of the world, China isn’t known as a leader in environmental mindfulness.

Forest-dwelling bird species are disappearing from some of South Africa's indigenous forests, with forest birds in the Eastern Cape being the most affected.

A group of scientists is recommending giving the world’s nature reserves a makeover to defend not only flora and fauna, but people, too.

Scientists in this week’s Proceedings of the National Academy of Sciences argue that the world’s protected areas such as nature reserves, traditionally havens for endangered animals and plants, can be made better if they ratchet up benefits that directly help people. The world’s nature reserves not only defend nature for nature’s sake, but also can curb erosion, prevent sandstorms, retain water and prevent flooding and sequester carbon. The authors include more of a place for people – judiciously.
