Most butterflies sport colourful, eye-catching wings. But some species flit about using mostly transparent wings. Researchers have now uncovered the tricks that one of these — the glasswing butterfly (Greta oto) — uses to hide in plain sight.
Researchers viewed the wings of these Central American butterflies under the microscope. There they spied sparse, spindly scales overlaying a see-through wing membrane. That membrane also has antireflective properties. It’s that combo that makes these insects so stealthy.
Do humans really need other species? Yes! millions of organisms are needed to keep ecosystems in balance and ensure everyone can survive. Most importantly, #research shows other species make us happy! Research shows that people are healthier and more content when they are around other species of plants and animals. They need to experience the sights, sounds, smells, feel and taste of other organisms for mental and physical health. This drive is called “biophilia,” meaning love of living things. #Boycott4Wildlife
The definition of refugee or displaced person is someone fleeing a life-threatening crisis. The emerging refugees of this century are fleeing unliveable environmental conditions brought about by climate change and other complex interrelated factors including conflict, disease and famine. Humans and non-human beings alike are becoming climate change refugees. The choices are stark and clear – move and live or stay where you are and perish.
With only 74 individuals left, the remarkable and beautiful Javan Rhino is on the brink of extinction and can be found on one of the most densely populated islands in the world – Java. Boycotting palm oil is how you can help them. Sunarto, Universitas Indonesia The Javan rhino was once found throughout many partsContinue reading “How do we protect the rapidly disappearing Javan Rhino?”
From Roman classics to British tabloids, humans have long celebrated the curious and remarkable ability of birds to imitate the sounds of humans and other animals. A recent surge of research is revealing how and why birds use vocal mimicry to further their own interests, as we discuss in Biological Reviews. Anastasia Dalziell, Cornell UniversityContinue reading “The mimics among us — birds pirate songs for personal profit”
Knowing that chimpanzees and orangutans have personalities, feel emotions and are “almost human” comes as no surprise to most people. However, linking the term “midlife crisis” to chimpanzees and orangutans seems to be somewhat shocking and controversial as we’ve seen from the flurry of interest produced by a paper published this week. Carla Litchfield, UniversityContinue reading “Do chimpanzees and orangutans really have midlife crises?”
Bonobos, sometimes called the “forgotten ape” due to their recent discovery and small numbers, titillate the democrat’s imagination. Before the 1970s, certain primatologists thought bonobos were strange chimpanzees because females govern in this primate society. Frans de Waal, the primatologist and popular writer, has done much to explain the fascinating lives of these “peace-loving apes”Continue reading “Bonobos can inspire us to make our democracies more peaceful”
Penny Orbell, The Conversation Most of us have experienced the overwhelming urge to yawn in response to another person yawning – but we’re not the only species to do this. Research published in PeerJ today shows bonobos – our closest evolutionary cousins – also experience “yawn contagion”, and, as in humans, the effect is influencedContinue reading “Contagious yawns show social ties in humans and bonobos”
Lowland tapir populations in the Atlantic Forest in South America are at risk of almost complete disappearance, scientists have estimated. Weighing up to 250 kg, the animal can adapt to most habitats in South America—but its populations continue to decline across its range. Today, its survival is seriously threatened: it can be found in justContinue reading “In the Atlantic Forest, the lowland tapir is at risk of extinction”
Tree kangaroos are so unusual that when Europeans first encountered them in Australia in 1872, they were sceptical. Who would believe a kangaroo could climb a tree? The Goodfellow’s tree kangaroo is a threatened species found in forests in the Central Cordillera mountain ranges of Papua New Guinea, from sea level to high in theContinue reading “Meet Chimbu, the blue-eyed, bear-eared tree kangaroo”
Carla Litchfield, University of South Australia Wild bonobos, like all Great Apes, spend long childhoods with their mothers, learning the skills they need to function as socially and emotionally stable members of their community. But orphaned bonobos at sanctuaries don’t have that kind of upbringing. Can they still learn the skills they need to getContinue reading “For primates, having a mother helps them learn social skills”
Did you know that Black #leopards only differ from other leopards by the colour of their coat, a genetic variation that’s #recessive also known as melanism? One of their threats is #palmoil #deforestation. Help their survival #Boycottpalmoil #Boycott4Wildlife in the supermarket
Sunanda Creagh, The Conversation Wild parrots name their chicks by teaching them an individual sound to identify them, researchers have found. Humans and dolphins create unique sounds by which individuals are identified and there was some evidence to suggest captive parrots created ‘contact calls’ – special calls used to identify family and friends. But untilContinue reading “What’s my name? How wild parrots identify their young”
Our world holds a whole host of glorious natural spectacles, from great starling murmurations to the ethereal display of coral reef spawning. But to me, none is more thrilling than catching a glimpse of a majestic macaw. Screeching their way through the Amazon rainforest, leaving scattered fruit, broken branches, and a considerable quantity of parrotContinue reading “Rainbow Cliffs: Why Parrots in the Amazon Eat Clay”
As humans, we live in a colourful world, but differences in visual systems means that not all animals see the world in the same way. Unlike other aspects of an object such as size or mass, colour is not an inherent property of an object but a result of the sensory system of the viewer.Continue reading “Inside the colourful world of animal vision”
Every living organism has a way of communicating. We may not be able to understand each other’s language. But its there and communication get passed from one organism to another. How do forests speak to us? If you have ever been into the woods and feel different ways nature talks to us. From the windContinue reading “Every Living Organism Has a Way of Communicating”
