New paper on the hindlimb membrane musculature of bats

Virtual dissections in ventral view of the calcar-depressor muscle complex of one hindlimb of (a) Myotis californicus, (b) Molossus molossus, and (c) Artibeus jamaicensis.

Ph.D. student Katie Stanchak just published a new paper describing  the variation in the membrane and limb musculature associated with the calcar – a neomorphic skeletal structure found in the hind limbs of most bats. By combining diffusible iodine-based contrast enhanced computed tomography (diceCT) and standard histological techniques, Katie found that the arrangement of the calcar musculature varies among bat species that have different flight ecologies. These results suggest that the calcar may have a functional role in flight maneuverability, an idea that Katie will be testing in later stages of her Dissertation.
