Monitoring is vital to conservation, enabling conservation scientists to detect population declines, identify threats and measure the effectiveness of interventions. However, not all threatened taxa are monitored, monitoring quality is variable, and the various components of monitoring are likely to differ in their rates of improvement over time. We assessed the presence of monitoring and monitoring quality, using a range of metrics, for all Australia’s threatened bird taxa from 1990 to 2020 (four assessments spanning 30 years). We used our assessments to understand decadal trends in the number of taxa monitored; monitoring quality; and the groups that conduct monitoring. The …

Maine Policy Review
Coastal ecosystems are facing increasing threats from human activities and environmental changes. Climate change, in particular, presents challenges for policymaking as it is causing significant changes to the oceans and coastlines, with social, economic, and environmental impacts on coastal communities. However, there is often a lack of data at the appropriate scales to address these concerns. Online tools that support the collection of citizen science and community science data can provide stakeholders and policymakers with a wealth of information and data on ocean-related topics, such as water quality, marine biodiversity, and ocean health. Citizen science platforms, like Anecdata.org, can facilitate …

Community Science Online: Building Capacity For Native Bee Monitoring, Lauren Vilen, Lisa Mason, Sarah Viders, Jill Zarestky
Journal of Human Sciences and Extension
Native bees are crucial for sustainable productivity in natural, agricultural, and urban ecosystems, but they are losing natural habitat spaces. Extension can facilitate community science programs to collect ecological data on native bee populations and support pollinator conservation. Native Bee Watch, an in-person community science program, transitioned to a hybrid format where volunteers received online training and support for conducting field-based data collection. This article presents the volunteers’ perceptions of the program training, support, and bee monitoring based on surveys and data analytics collected from technology tools. Study results indicate redesign successes and challenges and provide insight on how to …
Tidal Flooding In The Mid-Atlantic Region Of The Us: Water Quality Effects In The Lower Chesapeake Bay, Alfonso Macias Tapia
Tidal Flooding In The Mid-Atlantic Region Of The Us: Water Quality Effects In The Lower Chesapeake Bay, Alfonso Macias Tapia
OES Theses and Dissertations
Many coastal areas around the globe suffer from nutrient pollution and its environmental, social, and economic consequences. Nutrient inputs can come from point (e.g., the end of a pipe) and nonpoint sources, from which the former are better constrained as sampling need only be conducted at a discharge point. Given the temporal and spatially extensive nature of tidal flooding events, they can represent another type of nonpoint source of nutrients to adjacent water bodies heretofore, unexamined and quantified. Most studies examining impacts of tidal flooding have focused on threats to resources on land, such as urban infrastructure and human health …

USDA Wildlife Services: Staff Publications
Rose-ringed parakeets (Psittacula krameri; parakeets) are among the most invasive bird species worldwide. In their introduced range, populations of this species have caused negative effects on native species, natural environments, economies, and human safety. Lethal population management has been complicated by the intelligence of the birds, as they quickly alter behavior to avoid risks. Further, lethal control programs have been halted due to public opposition, as parakeets are considered to be charismatic by animal welfare advocates. The contraceptive DiazaCon has been demonstrated to effectively reduce fertility in captive parakeets. In field applications, any chemical control agents (e.g., toxicants or contraceptives) …

It Turned Into A Bioblitz: Urban Data Collection For Building Scientific Literacy And Environmental Connection, Kelly O'Donnell, Lisa Brundage
Publications and Research
In 2013, Macaulay Honors College redesigned its required science curriculum to focus on scientific literacy skills rather than content. Central to this shift was inclusion of a data collection event, a BioBlitz, to provide students with the basis for their own semester-long research projects. Students are teamed with naturalists in an urban green space to find as many species as they can in 24 h and to contribute to a global biodiversity database via the app iNaturalist. We have learned two important lessons: (1) developing an interdisciplinary curriculum with a high degree of experiential learning is more successful when both …

Taking Action: Turning Evolutionary Theory Into Preventive Policies, Orsolya Molnár, Marina Knickel, Christine Marizzi
MANTER: Journal of Parasite Biodiversity
The emerging infectious disease (EID) crisis has been challenging global health security for decades, dealing substantial damage to all socioeconomic landscapes. Control measures have failed to prevent or even mitigate damages from an accelerating wave of EIDs, leading to the emergence and devastation caused by the COVID-19 pandemic. In the wake of the pandemic, we must critically review our public health policies and approaches. Current health security measures are based on the evolutionary theorem of host-parasite coevolution, which falsely deems EIDs as rare and unpredictable. The DAMA protocol (Document, Assess, Monitor, Act) is nested in a novel evolutionary framework that …

Documenting Bombus Nevadensis In Minnesota, With Some Notes On Discerning It From B. Auricomus (Hymenoptera: Apidae), Zachary M. Portman, Chan Dolan
The Great Lakes Entomologist
In the face of well-documented declines in multiple bumblebee species, it is important to accurately identify species and properly delineate species ranges. Here, we document the range of Bombus auricomus (Robertson) and B. nevadensis Cresson in Minnesota, with particular reference to the unexpected discovery of B. nevadensis in St. Paul. We clarify the relative ranges of these two species and provide additional information on how to reliably identify them in Minnesota using color patterns and morphology, including differences in male genitalia. Our results support the consensus that B. auricomus and B. nevadensis are distinct species. Community science records were integral …

Coastal populations and hazards are escalating simultaneously, leading to an increased importance of coastal ocean observations. Many well-established observational techniques are expensive, require complex technical training, and offer little to no public engagement. Smartfin, an oceanographic sensor–equipped surfboard fin and citizen science program, was designed to alleviate these issues. Smartfins are typically used by surfers and paddlers in surf zone and nearshore regions where they can help fill gaps between other observational assets. Smartfin user groups can provide data-rich time-series in confined regions. Smartfin comprises temperature, motion, and wet/dry sensing, GPS location, and cellular data transmission capabilities for the near-real-time …

With acid rain among its direct consequences, air pollution has been documented to threaten manmade infrastructures, human health, and natural ecosystems. The COVID-19 pandemic restricted today’s source of air pollutants, as it compelled various countries worldwide to limit socio-economic activities and transportation to mitigate the transmission of SARS-CoV-2. However, local research on air pollution has tended to concentrate on the Philippines’ capital Metro Manila alone and the earlier stages of the COVID-19 pandemic in terms of location and time. Through citizen science, this study determined the pH levels of rainwater during the COVID-19 pandemic in areas within Central Luzon, Metro …

Surveys And Population Estimates Of A Distinctive Subpopulation Of Sandhill Cranes In The Fraser River Lowlands Of British Columbia, Myles M. Lamont
Proceedings of the North American Crane Workshop
A poorly understood subpopulation of sandhill cranes (Grus canadensis) breeds at scattered locations in the lower Fraser River Valley on the south coast of British Columbia. The area also harbors the northernmost population of overwintering sandhill cranes anywhere in its range. While sporadic monitoring has been carried out since the mid-1960s, no formal survey efforts have been attempted for the entire Fraser River lowland subpopulation. During 2014-2019 we collected groundbased survey data on presence and occupation of territories within the study area; this effort was supported by citizen science contributions. On 20 June 2019, we flew a fixed-width, …

Understanding Students’ Global Interdependence In Science Instruction, Walter S. Smith
Journal of Global Education and Research
Multiple American educational organizations such as the National Education Association, Association for Supervision and Curriculum Development, and the Council of Chief State School Officers have advocated for globalizing the K-12 curriculum. The National Science Teaching Association (NSTA) in a position statement on international education and the Next Generation Science Standards have produced goals and standards for internationalizing the science curriculum by addressing topics such as climate change, environment, and disease that cross borders. In contrast to those pronouncements on the curriculum, this article views global science education through an instructional lens that focuses on a students’ global interdependence in science …

IGC Proceedings (1997-2023)
For several decades, interventions geared towards the development of drylands have been the catalysts of much change in a rapidly evolving world, and learning how to build sustainable trajectories that take into account both cultural and contextual variations is becoming of increasingly great import. As local problems become intertwined, and given the difficulty of large-scale collective action, understanding these dynamics requires cognizance of all levels of knowledge governance systems and their interactions. So far as rangelands are concerned, the lack of easily accessible documentation encompassing all knowledge to date is a major impediment to their sustainable development. With this in …

In migratory birds, among- and within-species heterogeneity in response to climate change may be attributed to differences in migration distance and environmental cues that affect timing of arrival at breeding grounds. We used eBird observations and a within-species comparative approach to examine whether migration distance (with latitude as a proxy) and weather predictors can explain spring arrival dates at the breeding site in a raptor species with a widespread distribution and diverse migration strategies, the American Kestrel Falco sparverius. We found an interactive effect between latitude and spring minimum temperatures on arrival dates, whereby at lower latitudes (short-distance migrants) …

Master's Projects and Capstones
The Asia Pacific’s biodiversity is under threat. One significant step that can improve conservation is gathering data on what species exist in different areas over time, which can provide insight into ecosystem health. This is especially important in biodiversity hotspots, where high levels of endemism and anthropogenic risk overlap. Though it is one of the few places in the Pacific not classified as a biodiversity hotspot, Taiwan has an unusually high saturation in terms of biodiversity data points. Investigating the motives of biodiversity monitoring volunteerism is already a topic of growing scholarly interest, but relatively few studies have focused on …

Extensive, severe wildfires, and wildfire-induced smoke occurred across the western and central United States since August 2020. Wildfires resulting in the loss of habitats and emission of particulate matter and volatile organic compounds pose serious threatens to wildlife and human populations, especially for avian species, the respiratory system of which are sensitive to air pollutions. At the same time, the extreme weather (e.g., snowstorms) in late summer may also impact bird migration by cutting off their food supply and promoting their migration before they were physiologically ready. In this study, we investigated the environmental drivers of massive bird die-offs by …

The accuracy and precision of satellite sea surface temperature (SST) products in nearshore coastal waters are not well known, owing to a lack of in-situ data available for validation. It has been suggested that recreational watersports enthusiasts, who immerse themselves in nearshore coastal waters, be used as a platform to improve sampling and fill this gap. One tool that has been used worldwide by surfers is the Smartfin, which contains a temperature sensor integrated into a surfboard fin. If tools such as the Smartfin are to be considered for satellite validation work, they must be carefully evaluated against state-of-the-art techniques …

Atlantic tarpon (Megalops atlanticus, hereafter tarpon) are facing a multitude of stressors and are considered Vulnerable by the IUCN; however, significant gaps remain in our understanding of tarpon space use and movement. From 2018 to 2019, citizen scientists facilitated tagging of 23 tarpon with SPOT tags to examine space use and movement across the northern Gulf of Mexico. Movement-based kernel densities were used to estimate simplified biased random bridge-based utilization distributions and a joint move persistence model was used to estimate a behavioral index for each fish. Tarpon showed consistent east–west movement from the Alabama/Florida border to Louisiana, and utilization …

Urbanization and its associated processes affect wildlife in a variety of ways. Understanding how this increasing land use type affects biological communities is important for conservation efforts. Hummingbirds (family Trochilidae) are one taxon that has showed positive responses to varying intensities of urban development. We surveyed for Buff-bellied Hummingbird ( Amazilia yucatanensis), a species on its northern range-limits, in urban woodlands, residential, natural, and revegetated habitats. We examined how urbanization is affecting Buff-bellied Hummingbird populations in South Texas with point- count surveys and GIS analysis. We found that Buff-bellied Hummingbirds had greater relative abundances in urban settings when compared with …

Nearshore coastal waters are among the most dynamic regions on the planet and difficult to sample from conventional oceanographic platforms. It has been suggested that environmental sampling of the nearshore could be improved by mobilising vast numbers of citizens who partake in marine recreational sports, like surfing. In this paper, we compared two approaches for measuring sea surface temperature (SST), an Essential Climate Variable, when surfing. One technique involved attaching a commercially-available miniature temperature logger (Onset UTBI-001 TidbiT v2) to the leash of the surfboard (tether connecting surfer and surfboard) and the second, attaching a surfboard fin (Smartfin) that contained …

Ecological theory predicts that specialist insect herbivores are more likely to locate and colonize host plants growing in relatively sparse or pure stands compared to host plants growing amongst diverse non-host vegetation. We tested the hypothesis that increasing the apparency and accessibility of milkweed (Asclepias spp.) host plants in small polyculture gardens would boost their colonization by the monarch butterfly (Danaus plexippus), an iconic native species of conservation concern. We established replicated gardens containing the identical mix of milkweeds, flowering nectar sources, and non-host ornamental grasses but arranged in three different spatial configurations that were monitored for …

Accurate observations of the Earth system are required to understand how our planet is changing and to help manage its resources. The aquatic environment—including lakes, rivers, wetlands, estuaries, coastal and open oceans—is a fundamental component of the Earth system controlling key physical, biological, and chemical processes that allow life to flourish. Yet, this environment is critically undersampled in both time and space. New and cost-effective sampling solutions are urgently needed. Here, we highlight the potential to improve aquatic sampling by tapping into recreation. We draw attention to the vast number of participants that engage in aquatic recreational activities and argue, …
Differential Vulnerability To Window Collision Mortality Among Migratory Songbird Species, Olivia M. Colling
Differential Vulnerability To Window Collision Mortality Among Migratory Songbird Species, Olivia M. Colling
Electronic Thesis and Dissertation Repository
Millions of birds die annually in North America by colliding with windows. I investigated differential vulnerability to window collision among migratory songbird species using long-term citizen science datasets from two bird banding stations and the fatal light awareness program. I used negative binomial regressions to model species-specific catch ratios, a mixed-effects negative binomial regression to model trophic guild-specific catch ratios and mixed-effects logistic regressions to model the odds of catching different age classes. Species-specific vulnerability varied significantly. Blue-headed Vireos, Yellow-rumped Warblers and Ruby-crowned Kinglets were least vulnerable, while Ovenbirds, Common Yellowthroats, Fox Sparrows and Bay-breasted Warblers were most vulnerable. Foraging …

We used a coupled biological-physical connectivity model as a guide to plant two distinct hatchery-spawned strains of the eastern oyster, Crassostrea virginica, in the Lafayette River, Virginia during the summer of 2013 at two locations corresponding to virtual spawning locations within the connectivity model. We utilized single nucleotide polymorphism markers to test the model predictions by genotyping oysters recruited after planting two hatchery-spawned strains and examining interannual recruitment variability for two successive years. Two spat were identified …
