Dolphins In Ny? Researchers Turn To Boat Tours For Sightings, Aaron K. Tremper

Capstones

---

Before 2009, coastal bottlenose dolphins were a rare sight north of New Jersey. According to local researchers, large pods of bottlenose dolphins made their way that spring/summer along Long Island. While dolphin population data by state and federal wildlife regulators are spotty, studies by local scientists suggest more dolphins have been flocking to New York since 2009. Many researchers are turning to whale-watching ventures to learn more about what dolphins are up to in the Big Apple.

Investigating The Influence Of Available Drinking Water On Wildlife In Utah's West Desert, Danielle K. Finlayson

Theses and Dissertations

---

The availability of water is a limiting resource for many wildlife species in arid and semi- arid environments. Free water is essential for critical life stages for numerous species, including migration, reproduction, survival, and habitat selection. Riparian areas in the desert occur relatively infrequently, but support a disproportionally large percentage of plant and wildlife species found in arid environments. Our study covered two aspects of water use in the west desert of Utah. The first was assessing the impacts of nonnative ungulates (specifically feral horses and cattle) on natural springs, and how they influenced water quality, vegetation, and wildlife diversity …

Mr449: Allagash Wilderness Waterway Visitor Survey 2019, John J. Daigle, Ashley Cooper

Miscellaneous Reports

---

Quality in outdoor recreation can be defined as the degree to which recreation opportunities provide the experiences for which they are designed and managed. Key to protecting the backcountry experiences is an understanding of the different types of visitors to the Allagash Wilderness Waterway, each one with different needs and expectations, and the different levels of importance they place on recreation opportunities and conditions. In this report, visitor management implications and suggested further research focus on the diversity of use of the Allagash Wilderness Waterway in order to maximize the quality of the visitor experiences while protecting the unique natural …

Effects Of Patch Size, Fragmentation, And Invasive Species On Plant And Lepidoptera Communities In Southern Texas, James A. Stilley, Christopher A. Gabler

Biology Faculty Publications and Presentations

---

Simple Summary

Human land use has removed habitats, separated habitats into small and disconnected fragments, and introduced foreign species, which all harm wildlife. South Texas is highly diverse and home to many endangered species, but human disturbance threatens its wildlife. In south Texas, we poorly understand how different aspects of human land use influence wildlife diversity and abundance. We studied this by surveying plants and butterflies in 24 habitat fragments in south Texas that differed in size, shape, type, and land use history. Human disturbance was extensive, and foreign and weedy species were dominant in most habitats. Habitat types had …

Nebraska Wildlife Club, Jacob Spooner

Honors Expanded Learning Clubs

---

The goal of this club was for students to expand their knowledge on wildlife that exists both in and outside of Nebraska and for them to get a better idea the types of wildlife they might be able to find within the state. In addition, an objective of this club was to spark curiosity so that the kids might try to further explore aspects of wildlife on their own.

Main Achievements, Challenges, And Recommendations Of Biodiversity Conservation In China, Fuwen Wei, Xiaoge Ping, Yibo Hu, Yonggang Nie, Yan Zeng, Guangping Huang

Bulletin of Chinese Academy of Sciences (Chinese Version)

---

After nearly 30 years of development, China has basically realized the comprehensive conservation of biodiversity. Biodiversity conservation has been upgraded to a national strategy and incorporated into the top-level design, with laws and regulations gradually being improved and major scientific breakthroughs continuously being achieved. Through the implementation of major biodiversity conservation and ecological restoration projects, establishment of protected area system, and delineation of ecological red line, important ecosystems and endangered species have been effectively protected, and social participation and public awareness have been significantly improved. In addition, by signing a number of biodiversity-related international conventions and agreements and proposing the …

Artificial Nightlight Alters The Predator–Prey Dynamics Of An Apex Carnivore, Jesse R. Barber

Biology Faculty Publications and Presentations

---

Artificial nightlight is increasingly recognized as an important environmental disturbance that influences the habitats and fitness of numerous species. However, its effects on wide‐ranging vertebrates and their interactions remain unclear. Light pollution has the potential to amplify land‐use change, and as such, answering the question of how this sensory stimulant affects behavior and habitat use of species valued for their ecological roles and economic impacts is critical for conservation and land‐use planning. Here, we combined satellite‐derived estimates of light pollution, with GPS‐data from cougars Puma concolor (n = 56), mule deer Odocoileus hemionus (n = 263) and locations of cougar‐killed …

Evidence On The Effectiveness Of Small Unmanned Aircraft Systems (Suas) As A Survey Tool For North American Terrestrial, Vertebrate Animals: A Systematic Map Protocol, Jared A. Elmore, Michael F. Curran, Kristine O. Evans, Sathishkumar Samiappan, Meilun Zhou, Morgan B. Pfeiffer, Bradley F. Blackwell, Raymond B. Iglay

USDA Wildlife Services: Staff Publications

---

Background: Small unmanned aircraft systems (sUAS) are replacing or supplementing manned aircraft and groundbased surveys in many animal monitoring situations due to better coverage at finer spatial and temporal resolutions, access, cost, bias, impacts, safety, efficiency, and logistical benefits. Various sUAS models and sensors are available with varying features and usefulness depending on survey goals. However, justification for selection of sUAS and sensors are not typically offered in published literature and existing reviews do not adequately cover past and current sUAS applications for animal monitoring nor their associated sUAS model and sensor technologies, taxonomic and geographic scope, flight conditions and …

Noninvasive Genetic Sampling With A Bayesian Spatial Capture-Recapture Analysis To Estimate Abundance Of Roosevelt Elk (Cervus Canadensis Roosevelti), Makenzie Henk

Cal Poly Humboldt theses and projects

---

Determining abundance of Roosevelt elk (Cervus canadensis roosevelti) in central Humboldt County, California has presented a unique challenge to wildlife managers due to the dense forest habitat and the animals’ elusive behavior. As the elk population has increased, so has human-wildlife conflict, and wildlife agencies need efficient and repeatable methods for determining abundance to inform management decisions. Traditional monitoring methods such as helicopter surveys are ineffective due to low sighting probability and strong behavioral responses to the aircraft. They also often lead to biased sex ratios when the distribution of males and females varies across the landscape. Non-invasive …

Wildlife Forage Recovery Following Boreal Wildfire, Alexis Jorgensen, Jennifer Baltzer

Theses and Dissertations (Comprehensive)

---

Climate change is altering the boreal wildfire regime through increases in the extent and severity of burning and reductions in fire return intervals. These changes can alter the regeneration trajectory of canopy species and ground vegetation, with implications for wildlife habitat. There is some uncertainty about the timelines of when different animal species will use burned areas as their preferred forage taxa recover following fire, and how such recovery is mediated by environmental factors. Here, we aim to address these knowledge gaps through the following questions: 1) What are the main forage types consumed by boreal wildlife and how much …
