Project Update 3/2015

We continue to monitor and photograph hibernating bats under UV in New Jersey. Our overall numbers have declined and we suspect cold, wet springs. All the hibernating bats have Pd in varying amount...

Pre & post WNS pictures

First pix is of a pre-WNS MYLU. Second picture is of a post-WNS MYLU (wing has circled biopsy sites). Pre-WNS FL is a greenish grey and post-WNS is a teal blue that covers wing and tail. Post WNS

Pix of our bat colony 2 seasons ago

I've attached a few pix of Big Brown bats. We just had this colony form 2 seasons ago and it has held steady at about 50 bats. I have banded new bats each year (red 2 years ago and gold last year...

UV only sees active WNS lesions/fungal colonies. Once the bat arouses and leaves hibernation, it's immune system destroys the fungus so there is nothing left to see except skin damage.

Can we use ultraviolet light to identify bats that have survived white nose syndrome?

Jemmy- UV only really identifies fungus when fungus is active. When bat is warm and has exited hibernation, the bats immune system is actively destroying the fungus and the UV fluorescence diminishes. You cannot see the fungus normally on a bat in the field but you can see scars left by the fungal colonies. Thanks for your interest

UV can only see active fungus colonies. There is a progression of fluorscent change (healthy bat wings have a fluorscent signature) as colony developed (dark dots which expand into visible lesions) which then begin to be fluorscent under UV.

UV identifies the fungus regardless of survival. If bat survives first exposure (seen as fluorescent lesions) it will most probably have additional lesions next hibernation cycle. Only banding allows monitoring of long term survival.

No. UV only sees active Pd colonies. Unless subject bat has active Pd, you will only see normal fluorescence - which is usually blue. If subject bat had previous Pd and sustained wing damage, then you could possibly see scars from that. Differenting Pd scars from normal trauma scars can be tricky and can be done with practice but never will be 100% documentable.
