| comparative study on the innervation of nerves with calcitonin gene-related peptide, substance p and neurokinin a immunoreactivity in the walls of the cerebral arteries of small bats (mammalia: microchiroptera). | the distribution and origin of nerves with calcitonin gene-related peptide, substance p or neurokinin a immunoreactivity in the walls of the cerebral arteries were investigated in three microchiropteran species. the supply of nerves immunoreactive for substance p and neurokinin a to the bat cerebral arteries is confined mostly to the vertebral and basilar arteries. the density of innervation of calcitonin gene-related peptide-immunoreactive nerves and that of nerves with substance p or neurokini ... | 1990 | 1699170 |
| social organization in the bat myotis adversus. | studies in which the australian bat myotis adversus was marked and recaptured showed that mature males tend to be solitary, are strongly attached to a particular site, and apparently defend home sites. harem formation concurrent with mating has been observed, and the bond between the mother and her young extends beyond extends beyond nursing. | 1970 | 5441022 |
| characteristics of echolocating bats' auditory stereocilia length, compared with other mammals. | the stereocilia of the organ of corti in 4 different echolocating bats, myotis adversus, murina leucogaster, nyctalus plancyi (nyctalus velutinus), and rhinolophus ferrumequinum were observed by using scanning electron microscopy (sem). stereocilia lengths were estimated for comparison with those of non-echolocating mammals. the specialized lengths of outer hair cells (ohc) stereocilia in echolocating bats were shorter than those of non-echolocating mammals. the specialized lengths of inner hair ... | 2007 | 17653670 |
| sensory ecology of predator-prey interactions: responses of the an2 interneuron in the field cricket, teleogryllus oceanicus to the echolocation calls of sympatric bats. | we observed the responses of the an2 interneuron in the pacific field cricket, teleogryllus oceanicus, a cell implicated in eliciting avoidance flight away from bats, to acoustic stimuli representing the echolocation calls of bats as well as field recordings of search and gleaning attack calls of six species of insectivorous sympatric bats (west australia, australia: tadarida australis, chalinolobus goudii, nyctophilus geoffroyi; queensland, australia: vespadelus pumilus, myotis adversus; kaua'i ... | 2005 | 15886992 |
| complete mitochondrial genome of a large-footed bat, myotis macrodactylus (vespertilionidae). | the complete mitochondrial genome was sequenced and characterized newly from a large-footed bat, myotis macrodactylus (vespertilionidae). the total length of the m. macrodactylus genome is 17,562 bp, with a base composition of 34.0% a, 29.9% t, 23.0% c and 13.0% g. a short sequence of catacg is repeated 60 times in d-loop region. amino acid of m. macrodactylus was 92.7% similar to that of m. formosus. nucleotide similarity was 86.6% in all the other gene regions except for d-loop with low 66.8% ... | 2015 | 24102594 |
| the pineal organ of bats: a comparative morphological and volumetric investigation. | bats are seasonal breeders and roost under a wide range of lighting conditions, from broad daylight to the total darkness of subterranean passageways and caves. some are true hibernators. these characteristics and the paucity of information on their pineal organ prompted this investigation, which is based upon the pineals of 191 specimens of 88 species and 12 families of bats. comparative morphological and volumetric observations have been made on serially sectioned brains of each species. data ... | 1986 | 3693069 |
| changes in the fine structure of the testicular leydig cells of the seasonally-breeding bat, myotis adversus. | leydig cells of the bat, myotis adversus, have been examined by electron microscopy throughout fourteen months. during the breeding season the leydig cells become hypertrophied and are characterised by prominent areas of agranular endoplasmic reticulum and numerous small, membrane-bound granules. microperoxisomes are also observed. during the period of testicular regression. leydig cell size and the number of membrane-bound granules are greatly reduced. lipid droplets and dense bodies are more n ... | 1980 | 7407876 |
