The breeding habits of the bushveld gerbil Tatera leucogaster were examined in relation to rainfall and diet. Breeding is seasonal and associated with regular summer rainfall. The duration of the breeding season is variable, which is indicative of a temporally dynamic reproductive strategy. Litter size is large, and the punctuated iteroparity of T. leucogaster is associated with a xeric environment. The reproductive tactics of T. leucogaster are discussed in relation to other gerbils and rodents exhibiting similar reproductive strategies. Tatera leucogaster is a selective feeder on transient but seasonally available insects and seeds, but feeds on herbage when preferred foods are unavailable.Die voortplantingsgewoontes van die bosveldnagmuis Tatera leucogaster is ondersoek met betrekking tot reenval en dieet. Seisoenale voortplanting is geassosieer met gereelde somerreenval. Die duur van die paartyd is onbestendig, wat 'n tyd-dinamiese reproduktiewe strategie aandui. Die werpsel is groot, en die gepunktueerde, herhaaldelike voortplanting van T. leucogaster is geassosieer met 'n dorre omgewing. Die reproduktiewe taktiek van T. leucogaster word bespreek met betrekking tot ander nagmuise en knaagdiere met 'n soortgelyke voortplantingsstrategie. T. leucogaster voed selektief op insekte en saad wat tydelik in 'n bepaalde seisoen beskikbaar is, maar eet groen gewasse wanneer hulle voorkeurvoedsel onbeskikbaar is.

Nongeographic and geographic variation have been analyzed in the genus Brachyphylla , which belongs to the Antillean endemic subfamily Phyllonycterinae of the family Phyllostomatidae. Males were found to be generally larger than females; therefore, the sexes were analyzed separately for geographic variation. External measurements except length of forearm were found to display a high degree of individual variation. They were not used in subsequent analyses. Of cranial measurements, greatest length of skull and condylobasal length showed the least individual variation, whereas palatal length, postorbital breadth (in samples from west of the Mona Passage only), and rostral width at canines showed relatively high coefficients of variation. Variation in color was found not to follow any geographic pattern.Two species -Brachyphylla cavernanim and B. nana -were recognized in the genus. B. cavernanim occurs on Puerto Rico, the Virgin Islands, and the Lesser Antilles as far south as St. Vincent. Three subspecies are recognized. Populations of large bats occur on St. Croix in the Virgin Islands and the Lesser Antilles as far south as St. Vincent. The smallest individuals occur only on the island of Barbados. Populations of bats of intermediate size, described herein as a new subspecies, occur on Puerto Rico and most of the Virgin Islands. Brachyphylla nana is a monotypic species occurring on Cuba, Isle of Pines, Grand Cayman, Middle Caicos, and Hispaniola and as a sub-Recent fossil on Jamaica.
