Behavioral And Physiological Effects Of Heavy Metals On Fish: A Review And Preliminary Results, Diana V. Morales
Theses and Dissertations
Pollution, specifically heavy metal pollution, in various bodies of water has been a significant issue for decades. Research has been conducted on heavy metals and their effects on the environment, larger fish species, and humans since the 1970s (Skidmore, 1964; Adeniyi et al., 2007; Adeosun et al., 2015; Bawuro et al., 2018). It is known that zinc is a neurotoxin in some species and causes harm to the environment. It is also known that it causes harm to people if it is ingested or if they are exposed to it for long periods of time (Mahurpawar, 2015; Mizuno and Kawahara, …

Addition Of Inexpensive Lights To Aquatic Turtle Traps Improves Trapping Efficiency In Early Spring, Jenna B. Myers, Michael J. Bender, Maggie M. Woodall*, Jennifer L. Mook
Georgia Journal of Science
Aquatic turtles are essential contributors to many freshwater ecosystems, but they face a myriad of threats, necessitating periodic monitoring of population status. Increasing turtle trapping efficiency has the potential to improve conservation efforts, particularly when population sizes are low or sampling conditions are suboptimal. In an effort to improve trapping efficiency, we added LED lights to turtle traps in an attempt to attract kinosternid turtles. Our investigation into the effectiveness of LED lights as an attractant was based on evidence suggesting that these turtles may forage using both visual and olfactory cues. Lights significantly increased captures of kinosternid turtles during …

Journal of Bioresource Management
Euphorbia guyoniana (Boiss and Reut) is a plant of Euphorbiaceae family common throughout the northern Sahara and pre-desert regions. In traditional medicine, they are used in the treatment of various infections. Euphorbiaceae contain various chemical compounds families such as alkaloids, which give them a toxic effect. The toxic effects of seeds decoctions on mortality and development of 3rd instar larvae of Drosophila melanogaster are studied. A treatment by ingestion shows a good larvicidal activity of this extract. It was shown that the chemical compounds contained in the extract, act on the fly development cycle as most of pupae do not …

Unmanned aerial vehicles (UAVs) have become a popular wildlife survey tool. Most research has focused on detecting wildlife using UAVs with less known about behavioral responses. We compared the behavioral responses of breeding blue-winged teal (Spatula discors) (n = 151) and northern shovelers (Spatula clypeata) (n = 46) on wetlands flown over with a rotary DJI Matrice 200 quadcopter and control wetlands without flights. Using a GoPro camera affixed to a spotting scope, we conducted focal individual surveys and recorded duck behaviors for 30 minutes before, during, and 30 minutes after UAV flights to determine if …

Using Occupancy Modeling For Protocol Development And Habitat Assessment Of Necturus Maculosus In A Large Nagivational River, Alyssa Rachelle Jones
Theses, Dissertations and Capstones
Determining the survey effort required to reliably detect population change can be challenging for cryptic, elusive species. The secretive nature of amphibians makes it difficult to monitor population status and gather information about their natural history, including habitat use, which is essential for amphibian monitoring programs. The goals of this study were to examine if detection probabilities were affected by bait (i.e., light and food), breeding activity, and environmental covariates in a population of fully aquatic salamanders, Necturus maculosus. I evaluated the effectiveness of three bait treatments (light bait, food bait, combined light and food bait) and an unbaited …

Responses Of Arthropods To Fire And How Pollinators And Pollination Services Are Affected By Fire Severity, Blyssalyn V. Bieber
Electronic Theses and Dissertations
Fires impact ecosystems globally and due to climate change, there are shifts in fire regimes that impact ecological communities which provide essential ecosystem services. Focusing on arthropods, fire can influence this ubiquitous animal group in various way. We performed a comprehensive meta-analysis evaluating how fires impact differing arthropod functional groups. We found that overall, fire negatively effects community level responses for most functional groups with herbivores as the only exception showing some positive effects of fire. We also studied mixed-severity fires that burned >20 years ago and compared floral visitor communities across fire severities. We implemented a pollinator exclusion experiment …

Translocation Of Timber Rattlesnakes At Two West Virginia State Forests, Elizabeth Morgan Johnson
Theses, Dissertations and Capstones
In wildlife management, translocation is defined as the purposeful movement of an individual(s) from one place to another with a wildlife management goal. Translocation has become a common tool for mitigating negative human-wildlife interactions. We conducted a translocation study on timber rattlesnakes (Crotalus horridus) in response to numerous human-rattlesnake encounters with the goal of developing a translocation protocol that would allow natural resources personnel to mitigate negative encounters between the public and rattlesnakes and reduce impacts to local timber rattlesnake populations. In this study, we scaled translocation distance to site-specific home range characteristics to assess whether translocation outcomes …

Twenty-Year Status Of The Eastern Migratory Whooping Crane Reintroduction, Hillary L. Thompson, Nicole M. Gordon, Darby P. Bolt, Jadine R. Lee, Eva K. Szyszkoski
Proceedings of the North American Crane Workshop
Since the 10-year status update in 2011, the first parent-reared whooping cranes (Grus americana) were released in the Eastern Migratory Population, the ultralight program (UL) ended, and cranes were released at new sites in eastern Wisconsin. During 2011-2020, 117 captive-reared whooping cranes were released; 75 costume-reared (35 in UL and 40 in the Direct Autumn Release program) and 42 parent-reared. There were no significant differences in 1- or 3-year survival rates based on rearing technique or release site. The population size remained at about 100 cranes during 2010-2018 but then decreased during 2018-2020 due to a reduced number …

Drivers Of Annual Fledging In The Mississippi Sandhill Crane Population 1991–2018, Henry W. Woolley, Scott G. Hereford, Jerome J. Howard
Proceedings of the North American Crane Workshop
We studied trends in nesting, number of chicks fledged annually, and their environmental and biotic drivers in the wild population of Mississippi sandhill cranes (Grus canadensis pulla) on Mississippi Sandhill Crane National Wildlife Refuge during 1991-2018. Population size, number of nests, and number of chicks fledged annually increased slowly but significantly over the course of the study. Increases in population size were related to both number of wild-reared chicks fledged annually and number of captive-reared chicks released each year, but wild-reared chicks had significantly higher survivorship than captive-reared chicks. Hurricanes transiently raised mortality rates but only Hurricane Katrina …

Black Fly Survey Of A Whooping Crane Reintroduction Area In Eastern Wisconsin, Richard P. Urbanek, Peter H. Adler
Proceedings of the North American Crane Workshop
Nest desertion due to harassment by black flies (Simulium annulus and S. johannseni) during incubation has been a major factor inhibiting success of the reintroduced Eastern Migratory Population of whooping cranes (Grus americana). To avoid this problem, which was prevalent in the core reintroduction area in central Wisconsin, the Whooping Crane Eastern Partnership changed the primary reintroduction area to eastern Wisconsin in 2011. However, a 2010 assessment of black flies in that area had concentrated predominantly on the southern portion of the new area. In 2017-2018, we collected the first samples of black flies in …

Effects Of Release Techniques On Parent-Reared Whooping Cranes In The Eastern Migratory Population, Hillary L. Thompson, M. Susanna Glass, Marianne M. Wellington, Kim H. Boardman, Glenn H. Olsen
Proceedings of the North American Crane Workshop
Reintroduction of an Eastern Migratory Population (EMP) of whooping cranes (Grus americana) in the United States by release of captive-reared individuals began in 2001. As of 2020, the EMP has approximately 21 breeding pairs and has had limited recruitment of wild-hatched individuals, thus captive-reared juveniles continue to be released into breeding areas in Wisconsin to maintain the population. We investigated the effects of release techniques on survival, behavior, site fidelity, and conspecific associations of 42 captive-parent-reared whooping cranes released during 2013-2019 into the EMP. Individuals were monitored intensively post-release, then as a part of a long-term monitoring program, …

Vigilance Of Nesting Whooping Cranes In Juneau County, Wisconsin, Nicole M. Gordon, Darby P. Bolt, Hillary L. Thompson
Proceedings of the North American Crane Workshop
Vigilance plays an important role in the detection of possible threats and reducing the risk of predation, including during the incubation period. We examined the visual vigilance of incubating whooping cranes (Grus americana) in Juneau County, Wisconsin, during the 2019 nesting season. We deployed 9 trail cameras and tagged crane presence and behavior in 32,801 photos which were used in our analysis. We assessed individual nest and environmental variables and their effects on vigilant behavior of incubating cranes using linear mixed-models. Vigilant behavior was defined by a posture in which the crane’s head was up, neck was erect, …

Whooping Crane Stay Length In Relation To Stopover Site Characteristics, Andrew J. Caven, Aaron T. Pearse, David A. Brandt, Mary J. Harner, Greg D. Wright, David M. Baasch, Emma M. Brinley Buckley, Kristine L. Metzger, Matthew R. Rabbe, Anne E. Lacy
Proceedings of the North American Crane Workshop
Whooping crane (Grus americana) migratory stopovers can vary in length from hours to more than a month. Stopover sites provide food resources and safety essential for the completion of migration. Factors such as weather, climate, demographics of migrating groups, and physiological condition of migrants influence migratory movements of cranes (Gruidae) to varying degrees. However, little research has examined the relationship between habitat characteristics and stopover stay length in cranes. Site quality may relate to stay length with longer stays that allow individuals to improve body condition, or with shorter stays because of increased foraging efficiency. We examined this …

Snakes have been a traditionally under-represented organism in urban ecology, but they face similar, if not greater challenges in the face of growing urban sprawl. Eastern diamondback rattlesnakes (Crotalus adamanteus, EDBs) are under consideration for listing under the Endangered Species Act due to population declines resulting from historical human persecution and habitat loss. This study used radio-telemetry data from a long-term monitoring project of adult EDBs on a developed sea island in South Carolina, USA. I reclassified a National Land Cover Dataset to reflect relative mortality risk for snakes attempting to move through the landscape. High-risk cover types …
