| resource partitioning by insectivorous bats in jamaica. | in this investigation, we use variation in wing morphology, echolocation behaviour, patterns of habitat use and molecular diet analysis to demonstrate that six species of sympatric insectivorous bats in jamaica show significant differences that could explain resource partitioning among the species. high-intensity echolocating species that used shorter, broadband signals and had shorter, broader wings (pteronotus macleayii, pteronotus quadridens, mormoops blainvillii) foraged most in edge habitat ... | 2014 | 25187923 |
| evolutionary adaptations of cochlear function in jamaican mormoopid bats. | mormoopid bat species have their echolocation system adapted to different hunting strategies. to study the corresponding mechanical properties of their inner ear, we measured distortion-product otoacoustic emissions to assess cochlear sensitivity and tuning. mormoops blainvillii, pteronotus macleayii and p. quadridens use frequency-modulated echolocation signals, sometimes preceded by a short narrowband signal component. their distortion-product otoacoustic emission-threshold curves are most sen ... | 1999 | 10573863 |
