![]() Forensic pathology examination of the data strongly suggests that traumatic injury is the major cause of bat mortality at wind farms and, at best, barotrauma is a minor etiology. When cases with concurrent traumatic injury were excluded, this yielded a small fraction (6%, 5 of 81) of WF bats with lesions possibly consistent with barotrauma etiology. BC bats had only 1 case (2%, 1 of 42), but this was attributed to concurrent cranial fractures, whereas WF bats had a 20% (16 of 81) incidence. Bite wounds: 'There is extensive damage to soft tissue in the area and there are asymmetrical, bleeding wounds.' caused by creature attacks like crawlers and husks. The authors then examined for ruptured tympana, a sensitive marker of barotrauma in humans. The most common negative afflictions characters suffer from in Barotrauma are: Internal Damage (which can appear in different forms such as lacerations, blunt force trauma, gunshot wounds, bite wounds, organ damage, etc. In summary, 73% (190 of 262) of WF bats had lesions consistent with traumatic injury. Bite Wounds - Inflicted by many Creatures. WF bats had additional features of traumatic injury, including diaphragmatic hernia, subcutaneous hemorrhage, and bone marrow emboli. The skin is pierced and there are deep, bleeding wounds. WF bats had an increased incidence in fracture cases and specific bone fractures and had more external lacerations than BC bats. These resistances change depending on the limb of the creature, as well as the creature itself. During ascent, gas expansion can affect the lungs and gastrointestinal (GI) tract during descent, gas compression can affect ears, sinuses, air spaces in tooth fillings, and space contained by the diving face mask. Every creature in Barotrauma has specific resistances to damage. The authors next compared wind farm (WF) bats to building collision (BC) bats collected near downtown Chicago buildings. Barotrauma is tissue injury caused by a pressure-related change in body compartment gas volume in air-containing areas. These common tissue artifacts mimicked the diagnostic criteria of pulmonary barotrauma therefore, lung tissues from salvaged bats should not be used for barotrauma diagnosis. Postmortem time, environmental temperature, and freezing of carcasses all affected the development of vascular congestion, hemorrhage, and edema. Most tongue lacerations, puncture wounds, and buccal bites heal well without. They first examined the utility of lungs from salvaged bat carcasses for histopathologic diagnosis of barotrauma and studied laboratory mice as a model system. Trauma to the mandible may cause injury to the tongue or buccal mucosa. The authors evaluated competing hypotheses of barotrauma and traumatic injury to determine the cause. Migrating bats have increased mortality near moving turbine blades at wind farms.
