Pre- And Post-Partum Observations Of Signature Whistle Characteristics Of The Bottlenose Dolphin (Tursiops Truncatus), Robert Dutchen
Theses and Dissertations
This study analyzes whistle usage in an Atlantic bottlenose dolphin during birth. Findings show the mother produces two predominant whistle contours. Congruities between the whistles were compared and showed that the type 1 contour bears structural similarity to the first component of the type 2 contour, indicating combinatorial whistle construction.
Influence Of Group Change On Scent Marking In A Wild Population Of Verreaux’S Sifaka (Propithecus Verreauxi), Julia C. Dickerson
Influence Of Group Change On Scent Marking In A Wild Population Of Verreaux’S Sifaka (Propithecus Verreauxi), Julia C. Dickerson
Theses and Dissertations
This study analyzed scent marking rates of wild Verreaux’s sifaka during dispersals to investigate the impact of group changes on olfactory communication. Our results indicate that scent marking is affected by changes in group structure, but other methods of communication likely play a larger role in mediating group membership changes.
Effects Of Tropical Cyclones On Incubation And Hatch Frequency Of Marine Turtles In Broward County, Fl: An Exploratory Look For Potential Cues Of Environmentally Cued Hatching (Ech), Alexis Peterson
All HCAS Student Capstones, Theses, and Dissertations
Due to climate change and warming sea surface temperatures (SST), the intensity and frequency of tropical cyclones in the North Atlantic are continuing to increase. Tropical cyclones have many direct and indirect effects on coastal and marine species, such as sea turtles. Sea turtles are extremely vulnerable to climate change, due to having life history, physiology, and behavioral traits that are heavily influenced by environmental factors (Fuentes and Porter 2013). This study examined whether tropical cyclones serve as a triggering event for environmentally cued hatching (ECH) in loggerhead (Caretta caretta) and green (Chelonia mydas) turtle nests …

Effects Of Artificial Enrichment For Captive Western Lowland Gorilla (Gorilla Gorilla Gorilla) Activity Budgets, Angela Perretti, Rebecca Chancellor
Anthropology & Sociology Student Work
The benefits of enrichment and proper husbandry protocols and their applicability in wildlife research have been important topics of zoological research. Examining activity budgets of various species throughout zoological facilities reap biological, educational and conservation benefits. We collected data on the behavioral responses of five western lowland gorillas (Gorilla gorilla gorilla) (1 adult male, 2 adult females, 2 infants/juveniles) to a novel climbing structure in the outdoor enclosure at the Philadelphia Zoo. Over a period of 53 nonconsecutive months, we conducted 30-minute focals with 2-minute scan samples on the gorillas (488 total observation hours). We recorded frequency of behaviors for …

Lesson Plan: Habitat Fragmentation And Species Survival, Center For Urban Resilience
Module 06: Urban Biodiversity
The last two lessons explored how specific events impact biodiversity. This lesson adds to the concept that biodiversity is impacted by events. One such event is a change in land use. Habitat loss and fragmentation in urban settings impacts the survival of many species. Through this sequence of activities, students will find that the more connected and closer the habitat patches, the more likely the population is to survive. After exploring the online simulation, students will consider best practices for designing green space in their own urban area so that species are able to immigrate between the patches and increase …

Body States Of Asian Elephants Within And Around Protected Areas In The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Caitlyn Thai
Theses and Dissertations
Researchers are becoming increasingly aware that studying a species’ landscape of fear or, more broadly, their emotional states, can better inform cognitive questions about how animals navigate their environments. Vigilance behaviors are one way to determine how certain species perceive and respond to risky situations. Due to rapid environmental change, large animals such as elephants are experiencing risky encounters with humans more often than ever before. This study aims to investigate Asian elephants’ expressions of body states and how they might regulate their behavior based on perceived environmental risk or change. Specifically, we investigated the behavioral responses of Asian elephants …

281— Insect Soundscapes In Western New York, Sarah Metz, Mackenzie Bancroft, Dana Moukaled
GREAT Day Posters
Recent assessments of insect populations suggest significant declines in abundance and diversity across the globe. These assessments have not included western New York, so it is important to gain an understanding of the insect diversity and abundance in our local habitats, particularly grasslands. One noninvasive way to sample insect populations is to record the acoustic signals used by these animals. Male insects of several taxa advertise for mates in the late summer by producing species-specific vocalizations at potential breeding sites. We are using acoustic recordings to examine three local sites for their use by singing insects. Acoustic recordings collected during …

085— Success Of Batesian Mimicry In The Ant-Mimicking Spider Myrmarachne Formicaria, Niaomi Vanalstine, Julia Ophals
GREAT Day Posters
Myrmarachne formicaria (Salticidae) is an ant-mimicking spider which arrived in North America fairly recently, first noted in Ohio in 2001. It is important to understand how M. formicaria will impact other species as it spreads throughout North America. The goal of this study was to assess the success of Batesian mimicry used by the ant-mimicking spider in avoiding predation when in a staged encounter with another salticid spider. Myrmarachne formicaria mimic ants in the movement of their forelegs to resemble ant antennae, as well as bob their abdomen. The predator spiders were placed in a small petri dish with either …

Too Little Ph: How Freshwater Acidification Impacts The Abundance Of Macrophytes Consumed By Rusty Crayfish, Lauren Tucker, Paul Moore Dr., Jay Jones Mr.
Too Little Ph: How Freshwater Acidification Impacts The Abundance Of Macrophytes Consumed By Rusty Crayfish, Lauren Tucker, Paul Moore Dr., Jay Jones Mr.
Honors Projects
Anthropogenic activities such as the burning of fossil fuels result in increased atmospheric carbon dioxide (CO2) concentration. High levels of atmospheric CO2 cause chemical shifts in the carbon cycle. Changes in the carbon cycle due to increased CO2 levels lead to ocean and freshwater acidification. Freshwater acidification is problematic for species that synthesize their own shells as well as species that use olfaction for decision-making. Rusty crayfish (Faxonius rusticus) were subject to simulated freshwater acidification and fed two types of macrophyte, Chara (Chara braunii) and Myriopyllum (Myriophyllum sibiricum). A series …

Module 01: Introduction to Urban Ecology
This lesson was designed to complement instruction about the different categories of elements that make up an ecosystem: biotic, abiotic and man-made. Students will first categorize the things they pass on their way to and from school. Next, students will visit the field study site for the first time to familiarize themselves with the site, to understand that “nature” exists everywhere, and to experience the idea that humans—and their activities—are embedded in the environment and ecosystems.
