No Ape Left Behind: Orangutan Conservation Education Project, Danna Boshak Jan 2021

No Ape Left Behind: Orangutan Conservation Education Project, Danna Boshak

All Graduate Projects

Orangutans are critically endangered and if action is not taken, their extinction is imminent. Zoological institutions worldwide serve as an educational means to engage the broader public in conservation awareness and action behaviors. The Association of Zoos and Aquariums (AZA) created the Saving Animals From Extinction (SAFE) initiative to provide zoos with a platform to expand conservation efforts beyond their institutions. In collaboration with the Orangutan SAFE (OSAFE) education committee, the No Ape Left Behind: Orangutan Conservation Education Project develops educational activity resources that provide information about orangutan behavior and ecology as well as action items that individuals can take …


Wildlife Trade And Covid-19: Towards A Criminology Of Anthropogenic Pathogen Spillover, Piers Beirne Phd Dec 2020

Wildlife Trade And Covid-19: Towards A Criminology Of Anthropogenic Pathogen Spillover, Piers Beirne Phd

Department of Criminology

The general remit of this paper is the role of wildlife trade in pathogen spillover. Its underlying assumption is that, so far from being the exclusive domain of the life sciences, the study of pathogen spillover will be greatly enhanced by multi-perspectival approaches, including One Health and those employed here, namely, non-speciesist green criminology and critical animal studies. The paper moves from discussions of zoonosis, anthroponosis and wildlife trade to the emergence of COVID-19 in Wuhan, China. The paper recommends the abolition of all wildlife trade and the reclamation of wildlife habitat and broaches discussion of the extension of legal …


Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven Jun 2020

Vertebrates On The Brink As Indicators Of Biological Annihilation And The Sixth Mass Extinction, Gerardo Ceballos, Paul R. Ehrlich, Peter H. Raven

Harold W. Manter Laboratory of Parasitology: Library Materials

The ongoing sixth mass species extinction is the result of the destruction of component populations leading to eventual extirpation of entire species. Populations and species extinctions have severe implications for society through the degradation of ecosystem services. Here we assess the extinction crisis from a different perspective. We examine 29,400 species of terrestrial vertebrates, and determine which are on the brink of extinction because they have fewer than 1,000 individuals. There are 515 species on the brink (1.7% of the evaluated vertebrates). Around 94% of the populations of 77 mammal and bird species on the brink have been lost in …


Strategies To Improve Forage Utilization By Sheep Offered Forage Mixtures, Valens Niyigena Dec 2019

Strategies To Improve Forage Utilization By Sheep Offered Forage Mixtures, Valens Niyigena

Graduate Theses and Dissertations

In the first experiment, alfalfa and novel endophyte-infected tall fescue (NE+) forages were harvested after a killing frost, then mixed to formulate 4 different treatments; alfalfa alone, 67% alfalfa +33% fescue, 33% alfalfa + 67% fescue, or 100% fescue. After 3 months of storage as silage, Dorper ewe lambs (n = 20; mean BW = 34.7 ± 6.65 kg) were fed silage for ad libitum consumption, using 5 animals per treatment. Increasing the proportion of NE+ tall fescue improved (P < 0.05) silage total acids and lactic acid concentrations and decreased silage ammonia concentration. Digestible dry matter and organic matter intake and nitrogen utilization parameters decreased with increasing inclusion of NE+ in diet. In the second experiment, 16 Dorper ewe lambs (41.8 ± 4.61 kg BW) were assigned to 4 different treatments; alfalfa silage alone (0 g/kg; CONT) or alfalfa silage mixed with chopped sericea lespedeza (SL) hay to provide 90 (LOW), 180 (MED), or 270 g/kg SL (HIGH) on a dry matter basis in a randomized complete block design experiment with 2 period to provide 4 observations per treatment for each experimental period. Increasing the proportion of sericea lespedeza in the diet decreased dry matter and organic matter digestibility but did not affect feed intake. Fecal nitrogen (g/kg N intake) increased linearly (P < 0.01) while urinary N (g/ day and g/ kg of N intake) tended to decreased linearly and quadratically (P ≤ 0.1) with increasing the proportion of SL in diet. In the third experiments, 16 gestating Dorper ewe lambs (49.1 ± 4.61 kg BW) were allocated to 4 treatments; alfalfa silage alone (0% g/kg; CONT) or alfalfa silage mixed with lablab purpureus(LP) hay to provide 90 (LOW), 180 (MED), or 270 g/kg LP (HIGH) on a dry matter (DM) basis, in a randomized complete block design experiment with a total 8 replication per treatment. Supplementation of LP in diet increased quadratically (P ≤ 0.04) forage dry matter, organic matter intake, digestible dry matter and digestible organic matter intake (P < 0.05). Nitrogen apparently absorbed and urinary N both decreased linearly (P < 0.01) with adding more LP hay in diet. Harvesting and mixing alfalfa and fescue after a killing frost improved silage fermentation characteristics and supplementation of tannins from SL and polyphenol from LP altered N excretion.

Key words: lablab, sericea lespedeza, alfalfa silage, nitrogen, sheep.

A Delicate Balance: The Effects Of Habitat Type On Frog Communities: A Three-Pronged Study Examining The Effects Of Differing Habitat Characteristics On Anuran Diversity At El Centro De Investigación Sumak Kawsay In Situ, Ecuador, Zane Libke

Independent Study Project (ISP) Collection

We conducted 60 hours of visual encounter surveys and 3 hours of calling surveys on 6 different habitat types near Sumak Kawsay in situ Reserva (SKIS) near Mera, Pastaza, Ecuador. We defined habitat types defined by two variables: type of forest and proximity to water. The aim of the study was to determine what effect each variable has on anuran community composition. We compared the effectiveness of the two survey methods as well. High anuran community dissimilarity was found between each habitat type surveyed, indicating that both forest type and proximity to water are important factors that shape species richness …


Activity, Distribution, And Density Of Brown Rats (Rattus Norvegicus) On Misali Island, Pemba Island, Tanzania, Raegan Hasselbring Oct 2019

Activity, Distribution, And Density Of Brown Rats (Rattus Norvegicus) On Misali Island, Pemba Island, Tanzania, Raegan Hasselbring

Independent Study Project (ISP) Collection

This project investigated the activity, distribution, and density of brown rats (R. norvegicus) on Misali Island, Pemba. These factors were studied through field observations conducted over a 21-day observation period. Brown rats were highest in density around areas of human activity, attracted to the detritus, an ample food source. Although highest in density in these areas, a greater total population of brown rats was distributed in the coastal forest due to its proportion of area on the overall island. In the forest, the rats were most active along the coastal sections for unknown and unexplored reasons – possibly due to …


From Traps To Snapshots: Examining The Ecology Of Feral Predators And Native Small Mammals In Southeastern Australia Through Case Studies Of Two Faunal Sampling Methods, Katherine Karson Oct 2019

From Traps To Snapshots: Examining The Ecology Of Feral Predators And Native Small Mammals In Southeastern Australia Through Case Studies Of Two Faunal Sampling Methods, Katherine Karson

Independent Study Project (ISP) Collection

The red fox (Vulpes vulpes) and feral cat (Felis catus) are introduced mesopredators that significantly threaten native small mammal species in Australia. For decades, environmental managers have attempted to mitigate the effects of these introduced species. However, ecosystems are highly complex, making it difficult to assess the impacts of feral predators on communities of native fauna independent of other disturbances such as fire regime and habitat fragmentation. Cost-effective ecological monitoring programs are imperative for evaluating threats to native species and informing environmental decisions. New technology has become increasingly present in wildlife monitoring, and camera trapping has provided an alternative to …

Automated Bioacoustics: Methods In Ecology And Conservation And Their Potential For Animal Welfare Monitoring, Michael P. Mcloughlin, Rebecca Stewart, Alan G. Mcelligott Jun 2019

Automated Bioacoustics: Methods In Ecology And Conservation And Their Potential For Animal Welfare Monitoring, Michael P. Mcloughlin, Rebecca Stewart, Alan G. Mcelligott

Conservation Biology and Animal Welfare Collection

Vocalizations carry emotional, physiological and individual information. This suggests that they may serve as potentially useful indicators for inferring animal welfare. At the same time, automated methods for analysing and classifying sound have developed rapidly, particularly in the fields of ecology, conservation and sound scene classification. These methods are already used to automatically classify animal vocalizations, for example, in identifying animal species and estimating numbers of individuals. Despite this potential, they have not yet found widespread application in animal welfare monitoring. In this review, we first discuss current trends in sound analysis for ecology, conservation and sound classification. Following this, …


A Fishy Problem: Effects Of Atlantic Salmon Farming In The Pacific Ocean, Madeleine A. Griffith May 2019

A Fishy Problem: Effects Of Atlantic Salmon Farming In The Pacific Ocean, Madeleine A. Griffith

Student Theses 2015-Present

In this report, I explore the historical, climatological, economic, and ethical issues created by the contemporary industrial salmon farming practices off Pacific coast of the United States and Canada. Chapter 1 utilizes a variety of sources from Stephen Hume’s A Stain upon the Sea to Miller’s Living in the Environment, to examine the integral part salmon plays in both freshwater and marine ecosystems, the ecosystem services salmon contribute in wild and farmed settings, and the trends in salmon consumption around the world. Chapter 2 examines the historically relevant role salmon held among indigenous societies and how that role has changed …


Assessing The Impacts Of Gold Mining Deforestation On The Giant Otter (Pteronura Brasiliensis) In Madre De Dios, Peru, Erica Carcelen May 2019

Assessing The Impacts Of Gold Mining Deforestation On The Giant Otter (Pteronura Brasiliensis) In Madre De Dios, Peru, Erica Carcelen

Sustainability and Social Justice

Gold mining activity is highly prevalent in the Madre de Dios region, Peru. This activity poses large environmental impacts including deforestation, sedimentation of rivers, and pollution from mercury used during extraction. Mining activity is a major threat to the endangered giant otter as it destroys its preferred riverine habitat. Moreover, mercury used during gold extraction bio-accumulates in fish, which constitutes the entirety of their diet. In order to conserve the giant otter, it is necessary to identify conservation priority areas. In a reactive conservation planning approach, the objective of this work was to prioritize areas suitable as giant otter habitat …

Primates Of The Padangtegal Monkey Forest: Aggressive, Submissive And Affiliative: Interactions Between The Balinese Long-Tailed Macaques And Tourists, Marleigh Jenkins-Morse

Independent Study Project (ISP) Collection

Bali is one of Indonesia’s seventeen thousand islands and it has become a major tourist destination for visitors from all over the world. One of the most sought after attractions are the various monkey forests on the island, and one of the most renowned is the Padangtegal Monkey Forest in Ubud. As someone who studies Biological Anthropology, I am fascinated by primates both human and non-human. Within the Ubud Monkey Forest these two species come into contact on a daily basis.

Ethnoprimatology is a growing study, and it refers to the “interconnections between human and nonhuman primates” (McCarthy et al. …


Snowshoe Hares (Lepus Americanus) Alter Feeding Behavior In Response To Coyote (Canis Latrans) And Moose (Alces Alces) Cues At Diverse Vegetation Densities, Zachary K. Lankist Apr 2019

Snowshoe Hares (Lepus Americanus) Alter Feeding Behavior In Response To Coyote (Canis Latrans) And Moose (Alces Alces) Cues At Diverse Vegetation Densities, Zachary K. Lankist

Student Scholarship

Prey interpret predator cues as a warning and use them to assess the danger of a given area. Multiple prey species avoid chemical cues from predators at feeding sites because the risk of death outweighs the benefit of food. However, we lack information regarding avoidance of chemical cues from competitors as well as how foraging behavior changes alongside vegetative cover. To test if chemical cues and veget~tive cover alter prey vigilance, number of visits, and time spent at feeding sites, I observed snowshoe hares (Lepus americanus) in plots containing coyote (Canis latrans; predator) and moose (Alces alces; competitor) urine across …


Impacts Of Anthropogenic Waste On Tasmanian Pacific Gull (Larus Pacificus) Diet, Anne Bartlett Apr 2019

Impacts Of Anthropogenic Waste On Tasmanian Pacific Gull (Larus Pacificus) Diet, Anne Bartlett

Independent Study Project (ISP) Collection

Plastic pollution is one of the foremost environmental issues that the world is currently experiencing. The effects of plastic pollution are great and range from leaching of hazardous chemicals into the environment to ingestion of plastic waste by wildlife, including seabirds. Due to the high rates of plastic consumption by seabirds, many recent studies have been performed to determine the biological impacts of plastic consumption on various seabird species. The Pacific Gull (Larus pacificus) is the world’s largest sea gull and the only gull endemic to Australia, yet very limited information exists on this species. This study examines the impacts …


Effect Of Locality Recognition On Aggressive Behavior In The Red Swamp Crayfish, Procambarus Clarkii, Brett K. Muramoto, Tyler Farley Mar 2019

Effect Of Locality Recognition On Aggressive Behavior In The Red Swamp Crayfish, Procambarus Clarkii, Brett K. Muramoto, Tyler Farley

Seaver College Research And Scholarly Achievement Symposium

Climate change affects habitat globally, facilitating the expansion and rapid proliferation of invasive species which damage the newly invaded ecosystem. Intraspecific aggression among an invasive species is an important focus in ecological studies because it can contribute to their overall success as invaders. The crayfish species, Procambarus clarkii, inhabits freshwater streams in the Santa Monica Mountains (Los Angeles, CA) as an aggressive invasive predator. These invasive crayfish are well known for their highly aggressive interactions with conspecifics. It has been shown that body size, temperature, sex, and level of hunger influence their levels of aggression. However, there is a …


On The Brink Of Extinction: The Fate Of The Pacific Northwest's Southern Resident Killer Whales, Sabrina Wilk Jan 2019

On The Brink Of Extinction: The Fate Of The Pacific Northwest's Southern Resident Killer Whales, Sabrina Wilk

Pomona Senior Theses

The killer whales that roam the northeastern Pacific Ocean have been the objects of studies since the 1970s, making them the most well-studied population of orcas in the world. Three distinct ecotypes of killer whales (Orcinus orca), known as residents, transients, and offshores, share these waters. The ecotypes are morphologically and behaviorally distinct to the extent that some scientists consider them separate species, with residents eating salmon, transients specializing on marine mammals, and offshores preferring Pacific sleeper sharks and Pacific halibut. Resident populations have endeared themselves to the region's locals with their striking black and white markings and …


A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead Jan 2019

A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead

Antioch University Dissertations & Theses

Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive …


Integrating Multiple Genetic Detection Methods To Estimate Population Density Of Social And Territorial Carnivores, Sean M. Murphy, Ben C. Augustine, Jennifer R. Adams, Lisette P. Waits, John J. Cox Oct 2018

Integrating Multiple Genetic Detection Methods To Estimate Population Density Of Social And Territorial Carnivores, Sean M. Murphy, Ben C. Augustine, Jennifer R. Adams, Lisette P. Waits, John J. Cox

Forestry and Natural Resources Faculty Publications

Spatial capture–recapture models can produce unbiased estimates of population density, but sparse detection data often plague studies of social and territorial carnivores. Integrating multiple types of detection data can improve estimation of the spatial scale parameter (σ), activity center locations, and density. Noninvasive genetic sampling is effective for detecting carnivores, but social structure and territoriality could cause differential detectability among population cohorts for different detection methods. Using three observation models, we evaluated the integration of genetic detection data from noninvasive hair and scat sampling of the social and territorial coyote (Canis latrans). Although precision of estimated density was …


Bubble Stream Production By Belugas (Delphinapterus Leucas), Megan Slack Aug 2018

Bubble Stream Production By Belugas (Delphinapterus Leucas), Megan Slack

Theses

Bubble stream production in belugas has been poorly characterized and its function is not well understood. I examined behavioral states when producing bubble streams (“bubbling”), and when bubbling calls, to determine whether bubbling was significantly associated with a particular call category or behavioral state. Using 19 hours of video and audio recordings collected over a two-day period, I quantified bubble streams of a 4-month old calf and an unrelated adult female housed together. Based on the overall activity budgets and pool of vocalizations for both animals, I calculated the expected counts of bubble streams with and without vocalizations, assuming that …


Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms May 2018

Winter Bat Activity In A Landscape Without Traditional Hibernacula, Amy M. Hammesfahr, Rene E. Ohms

United States National Park Service: Publications

Abstract

Prior to 2014, bat research at Devils Tower National Monument (DETO) focused on bats present during the summer months. Biologists at DETO assumed local bats were strictly summer residents due to the presumed lack of typical habitat features associated with bat hibernation, such as caves and mines. This lack of traditional hibernacula features at DETO discouraged staff and research cooperators from studying winter bat populations. Despite the earlier assumption that bats were unlikely to hibernate on the monument, DETO documented significant winter bat activity through passive winter acoustic monitoring. This study is the first study at DETO that documents …


Towards Quantifying Relevant Land Cover Change: A Case Study In The Central Flyway Of The Monarch Butterfly, Hanna Lenee Ford May 2018

Towards Quantifying Relevant Land Cover Change: A Case Study In The Central Flyway Of The Monarch Butterfly, Hanna Lenee Ford

Graduate Theses and Dissertations

Over the past 20 years notable decreases in monarch butterfly populations have led researchers to begin evaluating the landscape for changes and seeking out opportunities for enacting conservation programs to better support their survival. The monarch butterfly has recently come under consideration for listing under the Endangered Species Act which has created a need for a more informed view of the landscape through which the migrate and breed, the central United States. In this research three spatially-explicit models are explored using the most applicable datasets currently available to address pressing policy and land manager decisions regarding monarch butterfly and pollinator …


Furs: Functionality, Fashion, And Franchise, Jenna Q. Detweiler Apr 2018

Furs: Functionality, Fashion, And Franchise, Jenna Q. Detweiler

Environment and Sustainability Honors Papers

Animal furs have been used in various manners through human history. Early humans cut crude shawls for warmth, and with the development of tools such as needles, closer-fitting clothing such as fur pants became possible. As time went on, products such as wool and cotton were used for clothing and, with fur alternatives, furs were reserved for the ultra-wealthy in some cultures. The image of fur as a luxury item has remained ever since, but simultaneously fur has become more accessible to the general public. Meanwhile, animal rights movements have successfully dampened interest in fur in some countries and communities. …


A Study Of The Urban Red Fox (Vulpes Vulpes) Population In Baton Rouge, Louisiana Using Social Media, Ahsennur Soysal Nov 2017

A Study Of The Urban Red Fox (Vulpes Vulpes) Population In Baton Rouge, Louisiana Using Social Media, Ahsennur Soysal

LSU Master's Theses

Foxes are timid yet resourceful animals that are integrated into many urban environments. Because they are elusive, collecting information about the number of urban foxes, their diet and spatial distribution, their interactions with the ecological community in their urban habitat, as well as residents’ response to them, is difficult. Involving stakeholders to participate in the data collection on wildlife via citizen science on social media is one way to overcome this complication, while simultaneously engaging residents in the ecology happening around them. Therefore, we used social media as the platform to engage the public to document and map the foxes …


How Useful Is Gsv As An Environmental Observation Tool? An Analysis Of The Evidence So Far., Katherine Nesse, Leah Airt Oct 2017

How Useful Is Gsv As An Environmental Observation Tool? An Analysis Of The Evidence So Far., Katherine Nesse, Leah Airt

SPU Works

Researchers in many disciplines have turned to Google Street View to replace pedestrian- or carbased in-person observation of streetscapes. It is most prevalent within the research literature on the relationship between neighborhood environments and public health but has been used as diverse as disaster recovery, ecology and wildlife habitat, and urban design. Evaluations of the tool have found that the results of GSV-based observation are similar to the results from in-person observation although the similarity depends on the type of characteristic being observed. Larger, permanent and discrete features showed more consistency between the two methods and smaller, transient and judgmental …


Rehabilitation Of An Injured Golden Eagle (Aquila Chrysaetos): A Case Study, Fida Muhammad Khan, Fakhar-I- Abbas, Abu Ul Hassan Faiz Sep 2017

Rehabilitation Of An Injured Golden Eagle (Aquila Chrysaetos): A Case Study, Fida Muhammad Khan, Fakhar-I- Abbas, Abu Ul Hassan Faiz

Journal of Bioresource Management

Habitat destruction and anthropogenic activities cause wild birds to migrate towards urban areas in search of food and sometimes nesting in high-roof buildings, where they are caught by local people using different techniques and are further used for hunting or recreational purposes. An injured Golden Eagle (Aquila chrysaetos) was found entangled in bushes near the vicinity of Balkasar Research Complex, Chakwal, Pakistan. After complete physical examination, a wound on the right wing and closed leg fracture was diagnosed. The successful treatment was done by anti-parasitic and anti-bacterial drugs with careful monitoring. Splint was adjusted after aligning the fractured …


Acoustic Signatures Of Habitat Types In The Miombo Woodlands Of Western Tanzania, Sheryl Vanessa Amorocho, Dante Francomano, Kristen M. Bellisario, Ben Gottesman, Bryan C. Pijanowski Aug 2017

Acoustic Signatures Of Habitat Types In The Miombo Woodlands Of Western Tanzania, Sheryl Vanessa Amorocho, Dante Francomano, Kristen M. Bellisario, Ben Gottesman, Bryan C. Pijanowski

The Summer Undergraduate Research Fellowship (SURF) Symposium

The Miombo Woodlands of Tanzania comprise several habitat types that are home to a great number of flora and fauna. Understanding their responses to increasing human disturbance is important for conservation, especially in places where people depend so directly on their local ecosystem services to survive. Soundscapes are a powerful approach to study complex biomes undergoing change. The sounds emitted by soniferous fauna characterize the acoustic profile of the landscapes they inhabit such that habitats with the highest acoustic abundance are considered as the most diverse and possibly more ecologically resilient. However, acoustic variability within similar habitat types may pose …


Elucidating The Effects Of Thiamethoxam Neonicotinoid On Honey Bee Learning Using The Proboscis Extension Response, David J. Shepherd May 2017

Elucidating The Effects Of Thiamethoxam Neonicotinoid On Honey Bee Learning Using The Proboscis Extension Response, David J. Shepherd

Undergraduate Honors Theses

In this study, the effects of the neonicotinoid pesticide, thiamethoxam, are examined through the Proboscis Extension Response (PER) in honey bees (Apis mellifera). PER is a form of classical conditioning applied to honey bees through scent and reward association which quantifies learning rates. Results between groups treated with thiamethoxam did not differ significantly from untreated control groups. Potential reasons for these results are discussed. The method and experimental apparatus for testing the PER assay are also discussed.


Distribution, Diversity, And Den Locations Of Canidae And Hyaenidae Species Across Habitat Type At Enashiva Nature Refuge, Grace Bullington Jan 2017

Distribution, Diversity, And Den Locations Of Canidae And Hyaenidae Species Across Habitat Type At Enashiva Nature Refuge, Grace Bullington

Independent Study Project (ISP) Collection

Due to the importance of top-trophic level predators have on their environment including regulating prey species and influencing ecosystem biodiversity, it is important to monitor top-trophic level predators to understand how they shape their ecosystem. While top-trophic level predators can benefit the ecosystem, they can also cause problems for surrounding human settlements like predation on livestock. Species in the Canidae and Hyaenidae families occupy the top-trophic level and can influence their ecosystem and cause human-wildlife conflict.

This study looked at the distribution, diversity, and den locations of Canidae and Hyaenidae species at Enashiva Nature Refuge over the course of 21 …
