Testing A Thermodynamic Approach To Collective Animal Behavior In Laboratory Fish Schools, Julia A. Giannini, James G. Puckett

Physics and Astronomy Faculty Publications

Collective behaviors displayed by groups of social animals are observed frequently in nature. Understanding and predicting the behavior of complex biological systems is dependent on developing effective descriptions and models. While collective animal systems are characteristically nonequilibrium, we can employ concepts from equilibrium statistical mechanics to motivate the measurement of material-like properties in laboratory animal aggregates. Here, we present results from a new set of experiments that utilize high speed footage of two-dimensional schooling events, particle tracking, and projected static and dynamic light fields to observe and control the behavior of negatively phototaxic fish schools (Hemigrammus bleheri). First, …

Aging Horses By Their Teeth, Karl Hoopes, Patricia Evans, Nancy Jack

All Current Publications

This publication tells how to pinpoint a horses age, within a fairly narrow range, by examining its teeth. Being able to pinpoint age can be of use to owners of unregistered horses or horses whose age is unknown for any reason. Many health and nutrition management decisions are directly related to age and dental wear, making it even more important for all horse owners to have a general understanding of how a horse’s mouth changes with age. From a historical perspective, up until recently when organized associations started keeping birth dates on registered horses, most horse professionals took great pride …

Saturday Night Live Club Lamb Sale, Tyler P. Wilkerson

Agricultural Education and Communication

“Competition is said to be the backbone of the stock show industry,” (Davis, 1998). A statement spoken in a 1998 thesis paper on the junior livestock industry still holds water in today’s world. Youth livestock exhibition, especially in California, continues to grow in the number of youth participants and the number of livestock entries at shows (Switzer, 2019).

It is the responsibility of livestock breeders to breed, raise, and sell their livestock to maximize the opportunity for youth to acquire livestock to show. In his research, Wendt discusses the capabilities of purchasing livestock through online platforms. He speaks to the …

Mixed Consequences Of Divorce On Reproductive Success Of Songbirds Nesting In Agricultural Hayfields, Kylee Dimaggio, Noah G. Perlut, Allan Strong

Environmental Studies Faculty Publications

Agricultural management, particularly haying, can cause synchronous nest failure of ground-nesting songbirds. As a consequence, these birds may subsequently renest and choose a new social mate (divorce). This study (1) quantified within-year and between-year divorce rates of grassland songbirds, and (2) determined if divorce rates differed after haying or predation-caused nest failure, and if so, whether divorce influenced reproductive success. From 2002 to 2017, we monitored 121 Bobolink (Dolichonyx oryzivorus) pairs and 436 Savannah Sparrow (Passerculus sandwichensis) pairs in an agricultural region of Vermont, USA. Within-year and between-year divorce rates were 0–84.9% for Bobolinks and 17–69.1% …

Heavy Winter Patch Grazing As An Alternative To Prescribed Burning On The Northern Great Plains, Jameson R. Brennan, Patricia Johnson, Ken Olson, Jennifer Lutze

SDSU Beef Day 2020 Summary Publication

Among management systems intended to increase heterogeneity on the landscape, patch burn grazing (PBG) is by far the most prominent and researched method. Though prescribed burning is seen as a healthy disturbance in grassland ecosystems, many landowners in the Northern Great Plains have an aversion to fire. This is due to safety and liability concerns as well as concerns over forage losses and limitations of labor, equipment, and insurance to successfully carry out prescribed burns. Therefore, there is a critical need to evaluate alternative, non-fire management strategies that will encourage rangeland heterogeneity. A study was conducted in 2017-2018 at the …

Differences In Relative Abundance Of Gnrh-I And Gnrh-Ii In Granulosa Cells Of Bovine Antral Follicles At Specific Stages Of Follicular Development, Jerica J. J. Rich, Emmalee J. Northrop, Kaitlin M. Epperson, Saulo Menegatti Zoca, Stephanie D. Perkins, Russell F. Daly, Robert A. Cushman, George A. Perry

SDSU Beef Day 2020 Summary Publication

Increased estradiol is the primary signal to initiate standing estrus, and cows that exhibit estrus prior to fixed-time artificial insemination have greater pregnancy rates than cows that do not. Therefore, understanding what factors may be present at the ovary that may regulate estradiol production is critical. A previous study reported that bovine follicles with greater follicular fluid concentrations of estradiol had decreased expression of GnRH-I and GnRH-II in granulosa cells (GC). The objective of this study was to characterize relative abundance of GnRH-I and -II mRNA within GC of follicles at specific stages of development. Beef cows were synchronized, and …
