Thing 1 And Thing 2 Are In A New Zoo: Changes In Behavior Of Amur Tigers Following Introduction To John Ball Zoo, Caitlin Gerke, Faith Hensley

Student Scholars Day Posters

Animals alter their behavior in response to changes in their environment such as alterations to their enclosure, social group, or husbandry routine. In 2018, two related, young adult Amur tigers (Panthera tigris altaica) were transferred to the John Ball Zoo (JBZ). The male siblings were given access to a spacious, wooded outdoor enclosure (area = 920 m²). We used Zoomonitor in 2018 and 2019 to conduct focal-animal sampling of the two males. We recorded state behaviors in 30 sec intervals of scan sampling, and all occurrences of event behaviors, both during 30 min sampling sessions. Our study objective …

Parasitism Of Female Neotibicen Linnei (Hemiptera: Cicadidae) By Larvae Of The Sarcophagid Fly Emblemasoma Erro In Wisconsin, Allen M. Young

The Great Lakes Entomologist

Herein it is reported an unusual case of parasitism of a female Neotibicen linnei (Smith and Grossbeck) by the sarcophagid Emblemasoma erro (Aldrich) in western Wisconsin. Sarcophagids typically attack male cicadas, locating them by the latter’s acoustical behavior.

Some members of the dipteran family Sarcophagidae are parasitic on male cicadas (e.g. Soper et. al. 1976, Lakes-Harlan et. al. 2000, Faris et. al. 2008, Stucky 2015). Parasitoids such as Emblemasoma species are attracted to larviposit on male cicadas by responding to the latter’s acoustical signals (Tron et. al. 2016). Sarcophagids, therefore, are generally not attracted to mute female cicadas. In this …

Granulosa Cell Proliferation Is Inhibited By Pge2 In The Primate Ovulatory Follicle, Patric S. Lundberg, Gil J. Moskowitz, Carmel Bellacose, Esra Demirel, Heidi A. Trau, Diane M. Duffy

Computer Science Faculty Publications

Prostaglandin E2 (PGE2) is a key paracrine mediator of ovulation. Few specific PGE2-regulated gene products have been identified, so we hypothesized that PGE2 may regulate the expression and/or activity of a network of proteins to promote ovulation. To test this concept, Ingenuity Pathway Analysis (IPA) was used to predict PGE2-regulated functionalities in the primate ovulatory follicle. Cynomolgus macaques underwent ovarian stimulation. Follicular granulosa cells were obtained before (0 h) or 36 h after an ovulatory dose of human chorionic gonadotropin (hCG), with ovulation anticipated 37-40 h after hCG. Granulosa cells were obtained from additional monkeys 36 h after treatment with …
