We need every tool at our disposal to stop feral cats and foxes from decimating Australia’s incredible wildlife after fires. Artificial refuges show promise.
New research suggests the gut bacteria of red and grey squirrels differ significantly, potentially explaining the decline of the native red and the success of its grey counterpart.
Antechinuses are tiny marsupials famous for their intense sex lives. Now, researchers have documented another unusual behaviour – the cannibalism of their own species.
Researchers have made a fascinating observation: a polar bear used a diving hunting technique, never before reported, to capture large moulting snow geese.
From dark dragonflies becoming paler to plants flowering earlier, some species are slowly evolving with the climate. Evolutionary biologists explain why few will evolve fast enough.
New research looks at how different species have managed to cross geographic barriers throughout history and whether their individual traits played a crucial role in these journeys.
