Vertebrate Scavenger Diversity And Ecosystem Services Along An Elevational Gradient In Central Nepal, Aishwarya Bhattacharjee

Dissertations, Theses, and Capstone Projects

A growing number of studies recognize the ecological significance of vertebrate scavengers, and several species belonging to this diverse, functional guild are of high conservation importance around the globe. Studies on taxonomic and functional components of biodiversity often use elevation gradients to comprehensively examine patterns and drivers across multiple spatial scales. Yet, there are relatively few elevational studies on large vertebrates or multi-taxa guilds, and the related variation of their ecosystem services. In particular, scavenger research has largely focused on local-scale studies or regional/global comparisons of local-scale investigations. Moreover, these studies primarily consider taxonomic community characteristics and the patterns of …

To investigate how UAS technologies could be safely and effectively applied to identify hazardous wildlife species to aviation operations as well as potential wildlife hazard attractants within the airport jurisdiction.

Plumage Characteristics Of The Long-Eared Owl (Asio Otus) In The Visible And Ultraviolet Spectra Of Light, Emily Griffith

All NMU Master's Theses

The study of plumage is a foundational aspect of ornithology, and the features of even a single feather can provide valuable information on an individual’s health, sex, or age. Recent discoveries on the abilities of birds to see in the ultraviolet (UV) spectrum has led to study of the UV-reactive characteristics of bird plumage and the biological significance of such plumage. Long-eared owls (Asio otus) possess a demonstrative capability to see UV light, and their plumage contains deposits of UV-sensitive pigments that fluoresce bright red when exposed to UV light. Little is understood about the origin and function of these …

Effects Of Early Corticosterone Treatment On Vocal Babbling In Wild Green-Rumped Parrotlets (Forpus Passerinus), Celia Rose Mclean

Theses and Dissertations

The stress axis of the endocrine system allows for animals to respond to environmental stressors in contextually appropriate ways. Elevated levels of the stress hormone corticosterone (CORT) in male songbirds can result in compromised song learning ability. Parrots form a sister group to songbirds, but it is unknown whether CORT affects vocal development in parrots. The goal of this study was to assess the effects of CORT supplements in green-rumped parrotlets (Forpus passerinus), a free-ranging parrot species in Venezuela. Bouts of vocal babbling were extracted from nest box videos and analyzed. CORT supplementation resulted in differences in babbling …

Habitat Use And Morphology Of Birds In "Intact" Amazonia Under Changing Climate, Vitek Jirinec

LSU Doctoral Dissertations

Neotropical forests contain the core of global avian diversity. Of these, the Amazon rainforest is the largest, but ~20% has already been lost to deforestation, inspiring research into the effects of clearing and fragmentation on forest birds. These studies have consistently shown that insectivorous birds that forage on or near the ground are the most sensitive species to forest disturbance. As a preamble to our study, we synthesized bird capture data collected over 40 years within continuous forest far from human disturbance. Remarkably, we found that terrestrial and near-ground insectivores have shown substantial abundance declines even within primary forest. The …

Remembering Elaine Bachel 1946-2021, Ruthie Stearns

Nebraska Bird Review

Elaine Bachel was born June 6, 1946, in Itasca County, Minnesota, and passed away May 22, 2021, in Lincoln. She lived in Minnesota until she was ten, and it was there that she developed her love of the outdoors, especially birds. When her father passed away, Elaine, her sister and her mother moved to Omaha to live with her grandmother. She graduated from Omaha South High School and then attended college in Omaha, graduating as a registered nurse in 1968. She worked for many years for Lincoln ENT physician Dr. Charles Barton. It was in working for him and traveling …

Incorrectly Aged, Identified And Classified: Revisiting Nebraska’S 1968 ‘Barnacle Goose’ Record, Joel G. Jorgensen, Stephen J. Brenner, W. Ross Silcock

Nebraska Bird Review

On 2 November 1968 in northeastern Otoe County, Nebraska, Milton Muncie harvested a bird (herein referred to as the 1968 specimen), subsequently identified as an immature Barnacle Goose (Branta leucopsis), from a flock of about 40 Cackling Geese (Branta hutchinsii; Cortelyou 1969). The occurrence was reported not only as the first record of a Barnacle Goose for Nebraska, but also the first record for the North American Interior and West (Cortelyou 1969). Cortelyou’s (1969) brief article also included a photograph of the mounted specimen. At the time and when subsequently reviewed by various authors, the identity of the 1968 specimen …

Paul Austin Johnsgard: Memories Of An Exceptional Naturalist, Allison E. Johnson, Charles R. Brown

Nebraska Bird Review

On May 28, 2021 the world lost one of its most dogged advocates, and we lost an amazing teacher, naturalist, and friend. Paul has told you in his own words in the previous pages where he was from, where he was educated, about the immense number of scholarly articles and books he published, and about his beautiful art that brought the wild to all of us (https://digitalcommons.unl.edu/zeabook/30/), but we wanted to share the person we knew Paul to be, and to relive some of our memories of him. While Paul’s body of work will continue to impact the ornithological and …

Spring Field Report, March - May 2021, W. Ross Silcock

Nebraska Bird Review

A total of 163 observers contributed to this report. This spring several observers were quite active statewide, resulting in interesting discoveries among waterfowl hybrids, subspecies distributions, breeding and spatial range expansions, and more than usual early and late dates and high counts, not to mention a couple of extreme rarities. Speaking of BONO, readers will note a new section under “Species Accounts” that deals with hybrids reported in Nebraska. A surprising 47 are listed, 26 of these waterfowl. If you like waterfowl hybrids, read on! This report deals with 14 such hybrids, four newly documented for the state. Several non-waterfowl …

Inter- And Intracontinental Migration By The Eastern Kingbird (Tyrannus Tyrannus), Daniel H. Kim, Lucas J. Redmond, James R. Fox, Michael T. Murphy

Biology Faculty Publications and Presentations

We recovered 12 archival geolocators deployed on Eastern Kingbirds (Tyrannus tyrannus) breeding in New York (NY; n¼3, 2 with 2 years of data), Nebraska (NE; n¼6, 1 with 2 years of data), and Oregon (OR; n¼3) to describe migratory routes, timing and rates of migration, nonbreeding season distributions, and migratory connectedness. NY fall migrants migrated along the Atlantic coast to Florida, flew either nonstop across the Gulf of Mexico (GoM; 2 of 3 birds) or stopped once along the way (Cuba and Cayman Islands in different years) to land in Yucatan/Central America. Fall birds from NE and OR arrived at …

Ecology Of Estuarine Birds: Differences In Desensitization Of Year-Round And Transient Species, Sarah Thomas

Honors Theses

Huntington Beach State Park in Murrells Inlet, SC, USA is considered a “hotspot” for birds, according to the eBird database (eBird, 2020). The park is also visited by approximately 300,000 people, annually (Hobdy, 2019). The causeway at the park is an area of high human and wildlife activity. Here, the differences in desensitization, or lack thereof, of year-round and transient bird species to the stimuli of vehicles and humans were determined. Multiple surveys of the birds at Huntington Beach State Park were conducted from 22nd September, 2019 to 13th June, 2020. Desensitization was quantified by use of a range finder …

The Intersection Of Past And Present, Hannah Welzbacker

Graduate Student Portfolios, Professional Papers, and Capstone Projects

Science often faces a crossroad between the past and present. Ever changing technology allows us to make new discoveries while at the same time, elements from past cultures need preserving. The three stories in this portfolio all highlight the intersection of past and present and how they can coexist. The first story focuses on a technological breakthrough that allows local researchers to better understand nocturnal migrations using acoustic monitoring. The second story explains the controversial Mayan Train project moving through South America and the implications for the economy, environment and culture. The final piece captures how members of the Blackfeet …
