Reindeer lichens reproduce sexually far more than scientists thought

Science
Jan. 29 (UPI) -- Like most lichen, reindeer lichen can reproduce both sexually and asexually, by sending out spores or simply cloning themselves. Previously, researchers assumed reindeer lichen, Cladonia stellaris, was primarily a clonal species, and would therefore feature relatively low levels of genetic diversity. Advertisement But according to a new genomic survey, published Friday in the American Journal of Botany, the reindeer lichen that blanket the forest floors of northern Canada have been doing a lot more gene-mixing than scientists thought. In other words, reindeer lichen have been having plenty of sex. Lichen are composite organisms featuring fungi and algae. Algae provide energy via photosynthesis, while the fungi secure nutrients from organic matter in rocks, soil and bark....

Technology
Reindeer, who fall prey to wolverines, wolves and lynx, are being fitted with sensors to protect them.It makes it easier for herders to track the animals across the remote Lapland forests where they roam.Sensors around the necks of the female reindeer are linked to the herders' smartphones, allowing them to rescue hurt animals more quickly and identify the cause of death for those killed.Next year the team behind the system also plan to track the predators.Up to 10% of reindeer are lost each year to traffic accidents or by falling prey to bears, wolves and wolverines.The worst predator for reindeer are lynx and there is a plan to attempt to track them in 2018 to identify when they are in close proximity to herds.The reindeer sensors were attached to a selection of animals at the bi-annual ...
