Little is known about tropical bats and the damage that collects on their wing membranes over time. Likewise, it is not known whether species or gender differ in the number of scars and tears on wings. This study analyzed the wing damage of three nectar-feeding bats and found that while overall wing damage was not significantly different between gender and species, specific areas of the wing membrane were statistically different. Females generally had higher rates of wing damage to the dactylopatagium major than males (two-way ANOVA, F = 4.21, p = 0.04). Another significant difference involved pregnancy; pregnant females had a higher average number of scars on the plagiopatagium than non-pregnant females (two-way ANOVA, F = 4.21, p = 0.05). As a result of this study, it has become apparent that further research is needed to understand why and how these significant differences occur.


Esta investigación analizó los daños del ala de tres especies de murciélagos que se alimentan de polen y néctar y encontró que los daños del ala en general no fueron significativamente diferentes entre género y especie, pero las áreas específicas de la membrana del ala eran estadísticamente diferentes.
