Karyotypes and chromosomal data are presented for eight bat species representing two families (Rhinolophidae and Vespertilionidae) from Hainan Island, China. The species investigated were Rhinolophus lepidus (2n = 62, FN = 60), R. pusillus (2n = 62, FN = 60), R. affinis (2n = 62, FN = 60), R. sinicus (2n = 36, FN = 60), Myotis horsfieldi (2n = 44, FN = 52), Pipistrellus abramus (2n = 26, FN = 4...

eventeen specimens of the rare Yucatan vesper mouse, Otonyctomys hatti, are now known from Belize, Guatemala, and the Mexican states of Campeche, Quintana Roo, and Yucatan. We herein report a second specimen of O.hatti, from Belize, extending the known geographic range of the species 95 km te the southeast in the country. This is the first location at which O. hatti has been taken sympatrically...

Juliomys is a small rodent from the family Cricetidae which inhabits the Atlantic forest and forests from Argentina to eastern Brazil. The three species recognized so far have different karyotypes. In this paper, we describe a new karyotype with 2n = 32, FN = 48 found in Juliomys specimens from a high-altitude area in the Atlantic forest of southern Brazil. The karyotype was analyzed after G- a...

constitution was undertaken. L1210/Mes. has a tetraploid modal chromosome number, the chromosomes of which resemble, although in increased quantity, those of the original LI210 lymphoma of the mouse. However, a new marker chromosome, a long, biarmed dicentric, appeared in 8.6% of the L1210/Mes. cells examined. L1210/Mes. is capable of back-transfer in BDP! mice, where a gradual shift in stemlin...

In this study, the morphology, anatomy, pollen morphology, leaf and seed micromorphology and karyology of the Turkish endangered endemic Physoptychis haussknechtii were investigated in detail for the fi rst time. The species was studied in terms of detailed morphology. Basal leaves are narrowly spatulate and cauline leaves are linear to oblanceolate; both leaves are covered with fl attened stal...
