Shopping for Clothes, Caveman Style

New findings in Spain show that early man seems to have hunted cave lions for their pelts. And why not? Lion and leopard was still fashionable back then. These were considered some of the largest lions that may have ever lived. So their pelts were large allowing early man to do a lot with them.

The abstract:

Pleistocene skinning and exploitation of carnivore furs have been previously inferred from archaeological evidence. Nevertheless, the evidence of skinning and fur processing tends to be weak and the interpretations are not strongly sustained by the archaeological record. In the present paper, we analyze unique evidence of patterned anthropic modification and skeletal representation of fossil remains of cave lion (Panthera spelaea) from the Lower Gallery of La Garma (Cantabria, Spain). This site is one of the few that provides Pleistocene examples of lion exploitation by humans. Our archaeozoological study suggests that lion-specialized pelt exploitation and use might have been related to ritual activities during the Middle Magdalenian period (ca. 14800 cal BC). Moreover, the specimens also represent the southernmost European and the latest evidence of cave lion exploitation in Iberia. Therefore, the study seeks to provide alternative explanations for lion extinction in Eurasia and argues for a role of hunting as a factor to take into account.

White Nose Washington

Earlier this year White Nose was discovered for the first time in the Pacific North-west. This is disheartening news.

White Nose Syndrome
Generalized spatiotemporal spread of Pseudogymnoascus destructans across North America since the initial detection of white-nose syndrome (WNS) in New York in 2006. Map from http://msphere.asm.org.

The question begs: what can we do more to prevent this spread? Obviously we can stop visiting caves. But are there steps we can take before we reach that conclusion? What do you think?

From the article:

On 11 March 2016, a moribund little brown bat (Myotis lucifugus) was found in King County, WA (United States), and submitted to a local wildlife rehabilitation center. The animal presented with dried and contracted areas of crusted skin on the wings and died 2 days later. Swab samples of the wings were positive for P. destructans by real-time PCR (8), and the bat was confirmed to have WNS in accordance with defined histopathologic criteria (9). An isolate of P. destructanswas obtained by culturing a portion of wing skin on Sabouraud dextrose agar containing chloramphenicol and gentamicin at 13°C.

In eastern North America, P. destructans appears to be spreading clonally, with all isolates exhibiting no genetic diversity at the markers examined (10). However, isolates of the fungus from Europe display significant genetic variation (11). To determine whether the isolate of P. destructans from Washington matched the clonal lineage from eastern North America, we conducted whole-genome sequencing using the Ion Torrent Personal Genome Machine (PGM) on the Washington isolate (NWHC#27099-001), as well as on three additional isolates of P. destructans from eastern North America. These isolates originated from M. lucifugus bats collected in Albany County, NY, in 2008 (NWHC#20631-008) and in Iowa County, WI, in 2016 (NWHC#26994-002) and a tri-colored bat (Perimyotis subflavus) in Jackson County, AL, in 2015 (NWHC#44797-145).
