Characterization of Circulating Androgens, Cortisol and Estrogens During Normal, Abnormal and False Pregnancy in Bottlenose Dolphins (Tursiops truncatus) Under Managed Care

Autor: K. J. Steinman, G. A. Montano, T. R. Robeck

Publikováno v: Frontiers in Marine Science, Vol 8 (2021)

The few hormone studies on bottlenose dolphin (Tursiops truncatus) pregnancy with different reproductive outcomes, e.g., normal birth, stillbirth and abortion, have mostly focused on progestagens or relaxin. However, recent analysis of androgens, glu

Topographic Variations in Mobilization of Blubber in Relation to Changes in Body Mass in Short-Finned Pilot Whales (Globicephala macrorhynchus)

Autor: S R Noren, L Schwarz, T R Robeck

Publikováno v: Physiological and Biochemical Zoology. 94:228-240

Fat-level measurements used to indicate individual body condition and fitness are useful only when taken at a region along the body where fat responds to variations in caloric intake. Investigations to identify appropriate species-specific regions ar

The Value of Ex Situ Cetacean Populations in Understanding Reproductive Physiology and Developing Assisted Reproductive Technology for Ex Situ and In Situ Species Management and Conservation Efforts

Autor: J. K. O’Brien, T. R. Robeck

Publikováno v: O’Brien, J. K.; & Robeck, T. R.(2010). The Value of Ex Situ Cetacean Populations in Understanding Reproductive Physiology and Developing Assisted Reproductive Technology for Ex Situ and In Situ Species Management and Conservation Efforts. International Journal of Comparative Psychology, 23(3). Retrieved from: http://www.escholarship.org/uc/item/1n15q19h

Wild cetacean populations have uncertain futures in the face of shifting climate conditions and the continued encroachment of their unique ecosystem by human activities. Core conservation efforts focus on habitat protection and understanding the natu

Reproductive physiology and development of artificial insemination technology in killer whales (Orcinus orca)

Autor: T R, Robeck, K J, Steinman, S, Gearhart, T R, Reidarson, J F, McBain, S L, Monfort

Publikováno v: Biology of reproduction. 71(2)

Research was conducted to define the basic reproductive physiology of killer whales (Orcinus orca) and to use this knowledge to facilitate the development of artificial insemination procedures. The specific objectives were 1) to determine the excreto

Effect of cryopreservation methods and precryopreservation storage on bottlenose dolphin (Tursiops truncatus) spermatozoa

Autor: T R, Robeck, J K, O'Brien

Publikováno v: Biology of reproduction. 70(5)

Research was conducted to develop an effective method for cryopreserving bottlenose dolphin (Tursiops truncatus) semen processed immediately after collection or after 24-h liquid storage. In each of two experiments, four ejaculates were collected fro

Ultrasonographic evaluation of the effects of exogenous gonadotropins on follicular recruitment and ovulation induction in the Atlantic bottlenose dolphin (Tursiops truncatus)

Autor: T R, Robeck, J F, McBain, S, Mathey, D C, Kraemer

Publikováno v: Journal of zoo and wildlife medicine : official publication of the American Association of Zoo Veterinarians. 29(1)

Transabdominal ultrasonography and serum steroid concentrations were used to evaluate the effects of exogenous gonadotropin administration on ovarian activity of two anestrous bottlenose dolphins (Tursiops truncatus). The gonadotropin used for follic
