Are insecticides more toxic than we think?
August 6, 2015 12:15 PM -
Insecticides that are sprayed in orchards and fields across North America may be more toxic to spiders than scientists previously believed. A McGill research team reached this conclusion after looking at changes in the behaviour of individual Bronze Jumping Spiders both before and after exposure to Phosmet, a widely used broad spectrum insecticide. It is a finding with far-reaching implications for agricultural production and ecosystem health.
Horses and humans share facial expressions
August 6, 2015 09:08 AM - University of Sussex
Horses share some surprisingly similar facial expressions to humans and chimps, according to new University of Sussex research. Mammal communication researchers have shown that, like humans, horses use muscles underlying various facial features - including their nostrils, lips and eyes - to alter their facial expressions in a variety of social situations.
Can habitat protection save our disappearing bats?
August 5, 2015 01:26 PM - Cléa Desjardins, Concordia University
In summertime, bats are a common feature in the night sky, swooping around backyards to gobble up mosquitos. Bats also help with crops: they act as a natural pesticide by feeding on harmful insects. But these winged mammals are now under threat. As agricultural intensification expands across the world, the conversion of their natural habitats has caused a dramatic decline in population.
4 million years at Africa's salad bar
August 5, 2015 09:18 AM - University of Utah
As grasses grew more common in Africa, most major mammal groups tried grazing on them at times during the past 4 million years, but some of the animals went extinct or switched back to browsing on trees and shrubs, according to a study led by the University of Utah.
Ending Wildlife Crime Becomes Top Priority
August 4, 2015 04:50 PM - Jessica Ramos, Care2
The past few weeks have been filled with headlines of crimes against our wildlife from the heartbreaking loss of Cecil the Lion to five more elephant deaths. But justice for our wildlife is on the horizon. The United Nations recently recognized that wildlife crime matters, and it’s on a similar level as human, arms and drug trafficking.
Antarctic life is more diverse than previously thought
August 4, 2015 09:06 AM - British Antarctic Survey
The team of scientists, led by Monash University, along with colleagues from the British Antarctic Survey, University of Waikato in New Zealand, and Australian National University, looked at how recent investigations have revealed the continent and surrounding ocean is rich in species. They are also very highly diversified into a variety of distinct ecological regions that differ greatly from each other.
Trophy hunting is not the main reason for declining population of lions in Africa
August 3, 2015 07:02 AM - Lochran Traill & Norman Owen-Smith, The Ecologist
Africa has half as many lions as 20 years ago - but don't blame trophy hunting
The killing of Zimbabwe's Cecil the Lion has put a welcome spotlight on the alarming decline of Africa's lions, write Lochran Traill & Norman Owen-Smith. But to save the species, we should not obsess about trophy hunting, but tackle much more serious problems - like snaring and habitat fragmentation.
UN adopts resolution to attack wildlife crime
August 2, 2015 08:14 AM -
Faced with an unprecedented surge in wildlife crime, the UN this week adopted a historic resolution committing all countries to ramp up their collective efforts to end the global poaching crisis and tackle the vast illegal wildlife trade. Initiated by Gabon and Germany and co-sponsored by 84 other nations, the UN General Assembly resolution, Tackling the Illicit Trafficking in Wildlife, is the result of three years of diplomatic efforts and is the first time that every nation has acknowledged the seriousness of wildlife crime and the urgent need to join forces to combat it.
How bees naturally vaccinate their babies

When it comes to vaccinating their babies, bees don't have a choice -- they naturally immunize their offspring against specific diseases found in their environments. And now for the first time, scientists have discovered how they do it.
New study exposes negative effects of climate change on Antarctic fish
July 31, 2015 09:14 AM - Oxford University Press
Scientists at University of California Davis and San Francisco State University have discovered that the combination of elevated levels of carbon dioxide and an increase in ocean water temperature has a significant impact on survival and development of the Antarctic dragonfish (Gymnodraco acuticeps). The research article was published today in the journal Conservation Physiology.
