• Chromosomal variation and perinatal mortality in San Diego zoo Soemmerring's gazelles

      Steiner, Cynthia C.; Charter, Suellen J.; Goddard, Natalie; Davis, Heidi; Brandt, Margot; Houck, Marlys L.; Ryder, Oliver A. (2015)
      …For the past 35 years, the San Diego Zoo Global (SDZG) captive population of Soemmerring's gazelles has revealed complex karyotypes resulting from chromosomal translocations with diploid numbers ranging from 34 to 39... Low levels of genetic distance and nucleotide diversity among individuals, in addition to high relatedness values, suggested that outbreeding is less of a concern than inbreeding for maintaining a sustainable captive population….
    • Pretreatment of Addra gazelle (Nanger dama ruficollis) spermatozoa with cholesterol-loaded cyclodextrins improves cryosurvival

      Wojtusik, Jessye; Pennington, Parker M.; Songsasen, Nucharin; Padilla, Luis R.; Citino, Scott B.; Pukazhenthi, Budhan S. (2016)
      ...Our aim was to characterize Addra gazelle (Nanger dama ruficollis) ejaculate traits and to assess the effects of cholesterol-loaded cyclodextrin (CLC) on sperm cryosurvival. Fresh ejaculates were treated with CLC (0, 0.5, 1.5, 3.0, and 6.0 mg/ml) prior to cryopreservation.... Reported advances will facilitate establishment of a frozen repository and support the genetic management of this critically endangered north African desert antelope.
