PHILIPPI, Tom; Florida International University: The average shrimp versus the average plant: addressing spatial and temporal unpredictability with ephemeral pool crustaceans Our theoretical understanding of the selective pressure of temporal environmental unpredictability is built upon the reproductive output of the average individual each year. Similarly, analyses of spatial (microsite) variation mostly assume average years. These […]

TSUKIMURA, B.; LINDER, C.J.; NELSON, W.K.; California State University, Fresno; California State University, Fresno; California State University, Fresno: Ovarian Development Inhibition by Methyl Farnesoate in the Tadpole Shrimp, Triops longicaudatus Methyl farnesoate (MF), a crustacean hormone, is an analog of Juvenile Hormone III (JHIII), a juvenilizing hormone in insects. This studied examined whether MF, which […]

RIPLEY, B. J.*; BOHONAK, A. J.; SIMOVICH, M. A. ; Univ. San Diego; San Diego State Univ.; Univ. San Diego: Magnitude of environmental variation and mechanisms of hatching in ephemeral pool crustaceans Crustacean species persist in ephemeral wetlands because they “weather” the dry phases as resistant cysts. Cyst hatching is risky in these environments because […]

SIMOVICH, Marie, A.; University of San Diego: Introduction to the evolutionary challenges facing ephemeral wetland fauna. Ephemeral wetlands present their inhabitants with intriguing evolutionary challenges. Their often unpredictable, bi-phasic nature requires that organisms have unique life history adaptations in order to survive. The organisms must be able to reproduce quickly during the short aquatic phase, […]

SPEARS, T.; Florida State University: Comparisons of population genetic structure for three large branchiopods co-occurring in ephemeral pools in the Lake Munson Sandhills Region of the Apalachicola National Forest. The Lake Munson Sandhills Region of the Apalachicola National Forest south of Tallahassee, Florida is characterized by numerous ephemeral pools, many of which contain so-called “large” […]

ROTH, Terri L.; Center for Conservation and Research of Endangered Wildlife, Cincinnati Zoo & Botanical Garden: The Role of Science in Breeding the Critically Endangered Sumatran Rhinoceros (Dicerorhinus sumatrensis) The Sumatran rhinoceros is one of the most difficult mammals to breed in captivity. With a population of just three animals in the U.S. and virtually […]

ASA, Cheryl; Saint Louis Zoo: Recovery of Endangered Mexican Gray Wolves (Canis lupus baileyi) and Island Foxes (Urocyon littoralis) Captive breeding can be a critical component of recovery for endangered species. The Mexican wolf, extinct in the wild, became the focus of a binational zoo-based recovery plan and has been reintroduced into part of its […]

BERCOVITCH, Fred B; TOBEY, Jennifer R; Center for Reproduction of Endangered Species, Zoological Society of San Diego; Center for Reproduction of Endangered Species, Zoological Society of San Diego: Maternal Effort and Sex Differences in Koala Joey Development Maternal effort includes time, energy, and resources devoted to producing and rearing offspring. Sex biased maternal effort is […]

HILDEBRANDT, TB; HERMES, R; GOERITZ, F; Institute for Zoo Biology and Wildlife Research, Berlin: Development of assisted reproducion technologies for endangered species Assisted reproductive technologies (ART), such as artificial insemination, embryo transfer, ovum pickup, in vitro fertilization, intracytoplasmatic sperm injection and gamete or embryo cryopreservation, are widely applied techniques used in human reproductive medicine and […]
