NEW RESEARCH SHOWS THAT REMOVING the horns of black rhinos to make them less attractive to poachers is reducing their territory sizes and making them less sociable with each other.
The study, published in the journal PNAS, found that de-horned South African rhinos have home ranges that are 45 percent smaller than those of intact animals, and that they were 37 percent less likely to engage in social interactions.
"The big, dominant bulls that used to have very large territories that overlapped with a lot of females may now have much less territory and much less reproductive success," says Vanessa Duthé, who led the work at Switzerland's University of Neuchâtel.

Jump Around - Bagheera Kiplingi - The acrobatic spider with a predilection for veggie food
Spiders eat flies, right? everyone knows that the 45,000 or so spiders in the world are all obligate carnivores, more or less – eating other animals, mainly invertebrates. Nature, however, loves an exception, and one particular spider missed out on that ecological memo. It goes by the wonderful scientific name of Bagheera kiplingi, and its claim to fame is that its diet is – at least mostly – vegetarian.
Female of the Species - Zebras - A strong sisterhood is key to staying safe
Zebras are masters of confusion. Their collective noun is ‘a dazzle’, which is fitting since their bodies and behaviour have been surprising scientists for centuries.
See It, Save It? - Wildlife tourism can be a powerful ally in protecting nature - but it can also harm it. We weigh up the pros and cons.
The sums of wildlife travel aren’t as simple as more tourists equals happier nature. How much did my visit really contribute to the conservation of Lady Liuwa and her habitat – and was that outweighed by carbon emissions from my flights? Did my presence disturb the animals’ natural behaviour more than it reduced the threat of poaching or benefited local communities?The question of whether wildlife travel is, on balance, good for wildlife is a complex one – and there’s no simple answer.
