When mammoths roamed Vancouver Island      (via sciencedaily.com)     Original source 

Mammoths, the massive pre-historic ice age cousins of the modern-day elephant, have always been understood to have inhabited parts of British Columbia, but the question of when has always been a bit woolly. Now, a new study has given scientists the clearest picture yet when the giant mammals roamed Vancouver Island.

Fishing is causing frightened fish to flee when they should flirt      (via sciencedaily.com)     Original source 

Populations of squaretail grouper face an uncertain future as new research shows fishing that targets their spawning sites is causing males to be repeatedly scared away from their territories during their short mating meet-ups. By fleeing for safety, individuals are losing valuable time to catch the eye and court female fish.

Social rank may determine if animals live fast, die young      (via sciencedaily.com)     Original source 

Social rank may determine whether animals prioritize immediate fitness over long-term health, according to a study. Researchers studied macaques on a Thai island and found that the animals' unusual habit of washing their food is in fact based on social rank. Dominant monkeys quickly brush their food on their fur before eating it, along with mouthfuls of tooth-degrading sand, while lower-ranked monkeys obsessively wash their food in the surf. Citing the disposable soma hypothesis, the researchers suggest that high-ranking macaques are looking to quickly consume energy to mate and fend off challengers. But food-washing monkeys may be preserving their long-term health to produce more offspring over time. The findings could shed light on how the wear observed in the fossilized teeth of early humans relates to social structure.

Elephants on the move: Mapping connections across African landscapes      (via sciencedaily.com)     Original source 

Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.

The race to discover biodiversity: 11 new marine species and a new platform for rapid species description      (via sciencedaily.com)     Original source 

A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.

When it comes to DNA replication, humans and baker's yeast are more alike than different      (via sciencedaily.com)     Original source 

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the first time a molecular complex -- called CTF18-RFC in humans and Ctf18-RFC in yeast -- that loads a 'clamp' onto DNA to keep parts of the replication machinery from falling off the DNA strand.

Half a billion-year-old spiny slug reveals the origins of mollusks      (via sciencedaily.com)     Original source 

Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).
