Technological Accessibility For Wildlife Telemetry Research, Andrew Danielson

The Journal of Purdue Undergraduate Research

Over the course of two years, I conducted original research into improving accessibility for researchers in the field of wildlife telemetry. Wildlife telemetry is a technique used by biologists to track wildlife in the field, which requires the biologist to attach a small radio transmitter to an animal, usually using a specially designed collar, harness, or another means. These transmitters are battery powered and will emit or transmit a regularly timed radio signal that can be received by radio receivers carried by the researchers. Two issues faced by wildlife telemetry researchers are the cost of wildlife telemetry equipment and the …

Study Of The Brain Anatomy Of Three Extinct Marsupials: Thylacinus Cynocephalus, Thylacoleo Carnifex, And Silvabestius Johnnilandi, Francisco Garcia

Honors Program Theses and Research Projects

Marsupials are pouched mammals that today are mainly found in Australasia and South America. Marsupials have proven to be quite intriguing to evolutionary biologists who note how some marsupials resemble placentals in anatomy due to convergent evolution, with both marsupials and placentals filling similar niches in their respective environments. As of today, studies interested in marsupial brain evolution have published descriptions of cranial endocasts for several species of marsupials, with the number of descriptions seeing a massive boost over the last 20 years with the arrival of CT imaging technology. However, no comprehensive study of brain evolution in marsupials has …

Understanding Bigeye Scad (Selar Crumenophthalmus) In Southeast Florida: Age-Growth, Reproduction, And Diet, Mariah France

All HCAS Student Capstones, Theses, and Dissertations

In southeastern Florida, the bigeye scad (Selar crumenophthalmus) is highly regarded as a baitfish for targeting billfish and other large sportfishes, often commanding market prices as live bait exceeding $180 per dozen. Despite its economic significance, there is limited knowledge regarding the species within the Atlantic Ocean, especially the population that occurs in Florida. Bigeye scad were collected monthly from local bait shops in Pompano Beach, Miami, and Islamorada to assess age-growth, reproductive behaviors, and dietary habits. Specimens from May to August had the highest values for length-weight relationships and gonadsomatic index, indicative of a spawning season during …

Analyzing Head Morphology Trends With Increasing Population Density In A Jamaican Lizard Species, Lillian Durand

2024 Fall Honors Capstone Projects - Archive

Anolis lizards are model organisms for studying natural selection and evolutionary processes. One trait that is hypothesized to be advantageous for males is head size, as larger heads lead to stronger bite forces and increased likelihood in outcompeting other males for mates. To better understand how linked head size and intraspecific competition are, the head morphology of male A. lineatopus was analyzed among Jamaican populations with varying levels of population density. Population densities were determined using standardized plot surveys and mark resight models. Head dimensions and body condition for individual lizards were measured at each site. My study found that …

First Breeding Confirmation For Red-Breasted Nuthatch (Sitta Canadensis) Along The Big Bend Reach Of The Platte River, Jacob C. Cooper, Cody Mcgregor, Letitia M. Reichart, Janet Steele

Nebraska Bird Review

The Red-breasted Nuthatch (Sitta canadensis) is a highly nomadic species of North American nuthatch prone to large movements across the entire continent (Ghalambor and Martin 2020). This behavior has resulted in both a lack of geographic variation across the continent and propensity to colonize isolated patches of suitable habitat (Ghalambor and Martin 2020). In the Bessey District of the Nebraska National Forest (NNF), Red-breasted Nuthatches were one of the first coniferous-forest bird species to colonize and begin breeding in the isolated planted stands of pine (Zimmer 1913, Bray 1994). Despite the increasing number of records for the species …

Nebraska Bird Review

The 2024 NOU Fall Field Days were held in McCook on September 20–22, with approximately fifty-one people in attendance. The programs were held at McCook Community College Student Union. A special thanks to Boni Edwards and Jan Johnson for planning the meeting.

Field trips were led by Bill Flack—Medicine Creek Reservoir and Cambridge Park, Robin Harding—Red Willow Reservoir and Culbertson Trail, Joel Jorgenson—Swanson Reservoir and Hitchcock County, and T.J. Walker—Rock Creek Recreation Area and Dundy County. Counties included were Chase, Dundy, Frontier, Furnas, Hayes, Hitchcock, Lincoln, Perkins, and Red Willow.

Fall Field Report, August–November 2024, W. Ross Silcock

Nebraska Bird Review

First off, I should reiterate that records are only mentioned in this Introduction and in the text when they add to or fine-tune data included in BONO (Birds of Nebraska – Online (outdoornebraska.gov). It was my expectation that as the number of birders and in particular those reporting to eBird continue to increase, gaps in the database will be filled and my job will become simpler. However, this expectation is yet to be realized, likely due to increasing movements and activity among birds that appears to be due to increasing severity of weather events, such as heat, cold, and drought, …

Lateral Dispersal Of Adult Trichoptera: Flight Distance And Traveling Pattern, Peilin Tan

All Theses

Trichoptera species (caddisfly) are usually used as bio-indictors for surface water quality due to their sensitivity to environmental changes, and if assessing water quality with light-trapped adults, knowing their travelling patterns will improve the accuracy of such assessments. To investigate how far a caddisfly will migrate from their emerging stream, three streams in South Carolina with different widths (Wildcat Creek 1.2 m, Brasstown Creek 11.2 m and Chattooga River 26.95 m) were selected for this study with light traps placed at three distances (0 m, 50 m, 100 m) from the streams. How long and when? Both species richness and …

How Many Tiny Snails? Circumscription Of Three Species Of Pyrgulopsis (Mollusca: Gastropoda: Hydrobiidae)In Nevada Mountain Springs, Trenton Meadows

Theses and Dissertations

The springsnail genus Pyrgulopsis is one of the most diverse groups of freshwater gastropods in North America (Hershler, 2014), with many species displaying high levels of endemism (Hurt, 2003). This study attempts to circumscribe three putative species of springsnails: Pyrgulopsis serrata, Pyrgulopsis marcida, and a newly identified clade, referred to as Lineage C, from the Ruby Lake National Wildlife Refuge, Nevada, USA and nearby springs. Using an integrative taxonomic approach, we combined morphological, anatomical, and molecular data to examine species boundaries and evolutionary relationships.

Many lines of evidence were considered to determine species boundaries. Phylogenetic analysis of the mitochondrial …

Spatial Ecology Of American Bison On Vermejo Park Ranch, New Mexico, Kate Ann Asmus

School of Natural Resources: Dissertations, Theses, and Student Research

American bison (Bison bison) are a keystone species that impact grassland productivity, plant diversity, and landscape heterogeneity. We used GPS telemetry and a replicate herbivore grazing experiment on Vermejo Park Ranch in northeastern New Mexico to advance understanding of bison spatial ecology and grazing dynamics. First, we evaluated the potentially disparate influences of forage productivity and site fidelity on the size and selection of home ranges of bison. Home range size was strongly negatively influenced by forage productivity. However, home range selection was influenced more strongly by site fidelity than spatial variation in forage, as bison selected home …
