DNA Barcoding to Monitor Marine Mammal Genetic Diversity

Dec. 30, 2013 — Marine mammals are flagship and charismatic species, very attractive for the general public. Nowadays, they are also considered as highly relevant sentinel of the marine realm. Their presence and their welfare in an area is thought to indicate the health of the place, whereas their disappearance, their displacement, or a decrease in their abundance or health could reflect negative environmental changes, whether of anthropogenic origin or not.

Monitoring marine mammal biodiversity is often difficult to perform. If some species can be easily observed, others are more difficult to detect, because for instance, of their scarcity or their discrete behavior. One of the solution suggested by scientists is based on the organization of stranding networks, listing and recording marine mammal strandings, which represent a cost-effective means to follow the marine mammal biodiversity.

Meet the Enemy of Killer Fungus that Turns Ants into Zombies

This article was originally published at The Conversation. The publication contributed the article to LiveScience's Expert Voices: Op-Ed & Insights.

One of most famous fungi in the world is the “zombie ant fungus”. It takes over the mind of an ant, causing it to climb up a branch and cling to the underside of a leaf before mummification. Once locked in place, the mushroom-like fruiting body of the cordyceps sprouts from the ant and eventually releases its spores.

This ant-killing fungus goes by the scientific name Ophiocordyceps unilateralis and its modus operandi has made it something of a celebrity – inspiring an episode of the X files, the video game The Last of Us and even a Pokémon character.

Naked Mole Rat Named 'Vertebrate of the Year'

Famed as the world's longest-living rodent, the wrinkly faced naked mole rat has won Science Magazine's Vertebrate of the Year award, confirming that the contest is based on more than just looks. 

The naked mole rat, a subterranean rodent native to East Africa, can live up to 30 years, roughly nine times longer than mice of the same size. With two yellow buck teeth protruding from a pale, hairless body, the mammal may not be an eye pleaser, but it has an alluring longevity-related adaptation that has gripped researchers in recent years: It seems to be immune to cancer.

Woman badly injured by 'panicked stag' in Highlands

A woman has been badly injured by a stag while on holiday in the Highlands.

Local man Jim Hunter said it happened as he and a group of people walked to his home after a night out at a pub. He said the red deer had panicked.

The incident happened at Lochailort, near Fort William in Lochaber.
