Here are the notes that I have… I had to leave part way through the talk. Also please excuse any misspellings of names.
Bats and White Nose Syndrome
Diana Northrup – Microbioilogist
Debbie Buecher – Bat Biologist
Kenneth Ingram – Photographer
- Hibernation vs. Migration
Hibernation – Family Vespertilionidae
Migration – Family Phyllostomidae & Family Molossidae
Uses 20-30% of bat fat reserves
Bats find cold, humid sites
Cold slows metabolism and High Humidity reduces moisture loss
Can drop the temperature of hibernaculum 1-2 *C of ambient temperatures
– Heart Rate slows
– Respiration slows
– Suppression of Immune System occurs (this is where WNS attacks)
– Bats slowly live off fat reserves
– Risk of human disturbance
– an unplanned arousal can burn up to 15 days of hibernation fat reserves!
- White Nose Syndrome
Bat hibernacula 2*C-14*C
Cold damp caves provide year-round reservoirs (even when bats aren’t there, WNS can last)
- Clinical findings of WNS
White fuzzy noses
Depleted fat reserves
- WNS Findings
Fungus invades cells, causing loss of dermal integrity which reduces physical functions
- Why are some bats vulnerable?
Hibernation bat clusters promote transmission
Hibernation offers limited resources
- Huachuca Mountains of Southern AZ
Finding conditions perfect for WNS
- New Mexico WNS Search
1. Assess key caves for appropriate conditions
2. Test soils
3. Obtain bat microbiota
4. Test cultures
Currently NO WNS in New Mexico
- Actinobacteria – may be protecting bats
Researchers are testing whether actinobacteria can kill WNS
Actinobacteria IS present on our bats
WNS is causing 6 million pounds of insects (3000 tons) per year to NOT be eaten by bats.
Humans shed 10,000 skin cells per minute… ew.
Please add or correct any of my notes in the comments. Thanks !
