The declining salmon and whale numbers raise a critical question: Is the southern resident killer whale population solely reliant on the abundance of salmon? And, if so, since when?
These coordinated movements of a flock of starlings follow no plan or leader. Scientists used to think the animals must communicate via ESP to create these fast-moving blobs.
African wild dogs are used to evading hyenas and lions. Genetic research suggests they are using the same strengths to get around human development as well.
The researchers found tooth shape varied, depending on the types of food a carnivore regularly bites into – in much the same way we choose a kitchen knife depending on what we’re cutting up.
Looking a bit like enlarged woodlice, ancient trilobites crawled along the seabed and had an exoskeleton made of calcite — nature’s version of a suit of armour.
Past research has shown honeybees can add, subtract and even understand ‘zero’. But according to new findings, they can’t tell four flowers from five in natural settings.
Wildlife can smell and hear a fire coming, and have developed novel ways to evade it. But they must watch out for cunning predators rushing in for a feed.
