Muzzle White Syndrome (WNS) discovered in Canada
Tuesday 23 March 2010Muzzle White syndrome (WNS) Geolocation; functional map.
Thursday 4 March 2010The distribution map of observing cases of White Nose Syndrome is operational again. Thank you to those who have enriched their observations. You can continue to add points by paying particular attention to the accuracy of the coordinates that you enter (using the proposed tool to help you if you do not have precise coordinates) and comments. Attention to “copier-coller” when adding comments, thank you to prefer the direct hit in the input window.
see you soon!

WNS and wing damage
Thursday 4 March 2010
According to Reichard & Kunz (2009).
In an article recently published in Acta Chiropterologica, J.D. Reichard and T.H. Kunz have studied the evolution of wing damage (from mid-May to mid-August 2008) on 2 colonies Myotis lucifigus in the area affected by WNS (states of Massachusetts and New Hampshire, USA).For this, the authors developed an index of wing damage (Wing Damage Index, WDI) divided into 4 categories, allant the 0 (no damage) to 3 (major damage). The details of this classification can be found in the article that you can get by clicking here. The authors assume that individuals affected by WNS present WDI higher than unaffected individuals, and this could have a direct impact on their survival. A effet, Furthermore the function of flight, the wings are important in terms of thermoregulation, gas exchange, hydraulic equilibrium, etc.. and the authors believe that severe damage on the wings (WDI>2) can affect these functions and ultimately affect their hunting success.
In view of the data and assumptions presented in this article, It would be interesting to inspect the membranes (plagiopatagium et uropatagium) and note the index of wing damage (WDI) taken in more than its usual measuring the weight and length of the forearm, the latter two measures used to calculate body mass index (BMI : Body Mass Index = poids (one gr.)/length of AB (mm)). This applies to any capture, regardless of the period.

Tribute to Professor Otto von Helversen
Tuesday 2 March 2010A year already Otto von Helversen left us ! In the last issue of Acta Chiropterologica, Christian Voigt et al. (2009) He is honored. You will find here the article in question (in English).
