Nearly 6,000 years ago, our ancestors climbed arid rocky outcrops in what is now the Nigerian Sahara and carved spectacularly intricate, larger-than-life renditions of giraffes into the exposed sandstone. The remarkably detailed Dabous giraffe rock art petroglyphs are among many ancient petroglyphs featuring giraffes across Africa – a testament to early humans’ fascination with these unique creatures. We are still captivated by giraffes today, but many of these animals are at risk, largely due to habitat loss and illegal hunting. Some are critically endangered. To understand how giraffes are faring across Africa, conservation ecologists like me are studying how they interact with their habitats across vast geographic scales. We use space-age technology and advanced statistical approaches that our ancient ancestors could have scarcely imagined to understand how giraffes can better coexist with people. Giraffes are featured...

When the COVID-19 pandemic first emerged, many wildlife disease researchers like me were not too surprised. Some were intrigued it hadn’t happened sooner; after all, it is our job to observe, describe and study pandemic dynamics in animals. Amphibians, for example, have been undergoing a global panzootic – the animal version of a pandemic – for decades. In the late 1990s, researchers identified the amphibian chytrid fungus, which causes the often-lethal disease chytridiomycosis, as the probable culprit behind frog and salamander declines and extinctions from Australia to Central America and elsewhere that began 10, 20 or even 30 years before. Scientists have found this pathogen on every continent that amphibians inhabit, and the extensive global amphibian trade has likely spread highly lethal strains around the world. The amphibian chytrid fungus is widespread in some geographic regions, and, like the virus that causes COVID-19, it can mutate rapidly and take n...
