Animals are back at Gorongosa National Park after civil war, but the savanna community doesn’t look quite look like how it used to

Animals are back at Gorongosa National Park after civil war, but the savanna community doesn't look quite look like how it used toWhen civil war broke out in Mozambique more than 40 years ago, it largely spelled doom for animals in Gorongosa National Park, a 1,500-square-mile reserve on the floor of the southern end of the Great African Rift Valley, in the heart of the country. As the decades-long fighting spilled over into the reserve, many of the creatures became casualties of the conflict. Throughout the war and even for some time after, food insecurity drove people to kill the animals to feed themselves. The hunting and poaching were hardest on the large mammals. "More than 90% of the large mammals in the park were wiped out," said UC Santa Barbara ecologist Kaitlyn Gaynor, a postdocto...

Magnets and Magnetic Fields

Magnets and Magnetic Fields Magnets are highly misunderstood, and often interpreted as magic. But they're not magic! It's just science. Let's learn about what magnets are and what produces magnetism so that we can sound super smart at dinner parties, yes?

The secret behind male ornaments

The secret behind male ornaments

The secret behind male ornamentsThe tail feathers of the peacock, the enormous horn of male rhinoceros beetles, the protruding antlers of some deer: In nature, there are countless examples of features which at first sight may only have disadvantages for their owners. After all, it is more difficult to hide from a predator when one is wearing a colourful plumage, and large antlers do not make escaping in the forest any easier. As a rule, it is the male that has such characteristics. The evolution of male ornaments has therefore been fascinating to biologists since ever. Already Charles Darwin wondered of how such exaggerated, energy-consuming and in principle harmful structures could have been created by natural selection. Using the example of the swordtail fish (Xiphophorus hellerii), he e...
