The Husbandry and Captive Propagation of Forest Cobras,Naja melanoleuca

The maintenance and propagation of the Black mamba Dendroaspis polylepis at the Manyeleti Reptile Centre, Eastern Transvaal

“…Failure to achieve intromission is due usually to the 9's reluctance or refusal to lift her tail. Intromission in the Mexican milk snake Lamproptdtis triungulum sinuloue can also only occur when the 9 voluntarily opens the cloaca1 orifice (Gillingham et ul., 1977) and similar behaviour has been observed in courting Forest cobras Naja mdanoleuca (Haagner & Carpenter, 1988;Haagner, 1990).…”

NOTES ON THE CAPTIVE BREEDING OF THE BLACK SPITTING COBRA, NAJA NIGRICOLLIS WOODI (SERPENTES: ELAPIDAE)

“…The female was initially coiled around the clutch upon discovery but moved into the cover of a hide box when the cage was approached. No apparent guarding behaviour (Somma, 1988) was observed as in other elapids such as Naja me/ano/euca (Haagner, 1990) and Aspide/aps scutatus intermedius (Haagner and Morgan, 1992).…”

Pivotal temperature is not for everyone: Evidence for temperature‐dependent sex determination in three gecko species

“…The data on GSD are derived from the review (Augstenová et al, 2021) supplemented by Mezzasalma et al (2021), Pensabene et al (2023), and Pinto et al (2022). Temperature‐dependent sex determination (TSD) is well‐supported in Eublepharis macularius (Bull, 1987; Viets et al, 1993), Hemitheconyx caudicinctus (Anderson & Oldham, 1988; Viets et al, 1993), Tarentola mauritanica (Marques et al, 2023; Nettmann & Rykena, 1985), Tarentola boettgeri (Nettmann & Rykena, 1985), and Phelsuma grandis (Viets et al, 1994), newly in Pachydactylus tigrinus, Pristurus carteri , and Chondrodactylus laevigatus (this study). TSD was suspected in the genus Rhacodactylus (Seipp & Henkel, 2000), in Tarentola delalandii, T. gomerensis, T. angustimentalis, T. annularis (Nettmann & Rykena, 1985), Phelsuma dubia, Phelsuma guimbeaui, Phelsuma lineata, Phelsuma abbotti (Tytle, unpublished data in Viets et al, 1994), and Gekko japonicus (Tokunaga, 1985 but see Yoshida & Itoh, 1974).…”
