Yellowstone National Park thermal features regularly discharge various heavy metals and metalloids. These metals are taken up by microorganisms that often form mats in thermal springs. These microbial mats also serve as food sources for invertebrate assemblages. To examine how heavy metals move through insect food webs associated with hot springs, two sites were selected for this study. Dragon-Beowulf Hot Springs, acid-sulfate chloride springs, have a pH of 2.9, water temperatures above 70 oC, and populations of thermophilic bacterial, archaeal, and algal mats. Rabbit Creek Hot Springs, alkaline springs, have a pH of up to 9, some water temperatures …

Problems And Suggestions Of Building Scientific Decision-Making And Advisory Mechanism Of National Parks—Governance-Based Perspective, Yu Wei, Duowei Cheng, Yi Wang
Bulletin of Chinese Academy of Sciences (Chinese Version)
National parks are multi-factor, multi-functional and multi-dimensional complexes, which makes them difficult to follow the traditional administration and management modes, and need to explore the construction of a modernized governance system. An important step in enhancing the effectiveness of governance is to establish a reasonable, and efficient scientific decision-making and consultation mechanism. China has made remarkable progress in scientific decision-making and consultation in national parks. However, there are still some problems with the national parks’ decision-making process and effectiveness due to vague definition of authority and responsibility, dependence on departmentalized management paths, and inadequate upward and downward transmission of information …

Development Of The Quantitative Modelling Observation Protocol (Qmop) For Undergraduate Biology Courses: Validity Evidence For Score Interpretation And Uses, Lyrica Lucas, Anum Khushal, Robert Mayes, Brian Couch, Joseph Dauer
School of Natural Resources: Faculty Publications
Educational reform priorities such as emphasis on quantitative modelling (QM) have positioned undergraduate biology instructors as designers of QM experiences to engage students in authentic science practices that support the development of datadriven and evidence-based reasoning. Yet, little is known about how biology instructors adapt to the pedagogical movement towards incorporating QM opportunities for students in the courses they teach. This study presents the development of the Quantitative Modelling Observation Protocol (QMOP), a classroom observation instrument designed to support the need to characterise various approaches that instructors use to implement QM instruction in undergraduate biology. QMOP provides information about the …

Conservation is increasingly focused on preventing losses in species’ populations before they occur. Tracking changes in demographic parameters that can impact a population’s resilience in response to drivers of global change can support early conservation efforts. We assessed trends in population productivity (late summer juveniles per 100 females) relative to drivers of global change in 40 pronghorn (Antilocapra americana) herds across sagebrush (Artemisia spp.) steppe in Wyoming. Pronghorn are an iconic rangeland species that have been exposed to increasing levels of anthropogenic, climatic, and land-use change. Using data collected across the state of Wyoming, we (1) assessed …

Long Term Sustainable Use Of Demersal Gillnet And Demersal Longline In Western Australia’S Temperate Shark Fisheries - Fisheries Research Report 340, Matias Braccini, Jack Parker, Daniela Waltrick, Maddison Watt, Nick Blay, Clinton Syers
Fisheries Research Reports
The Temperate Demersal Gillnet and Demersal Longline Fisheries (TDGDLF) are one of the main commercial shark fisheries in Australia. Most fishers in the TDGDLF use demersal gillnets to target sharks with scalefish taken in smaller amounts. Demersal longlines are also permitted but are not widely used. Demersal gillnets are size selective, but they do not necessarily discriminate among species, catching target and non-target species.
The Western Australian Fishing Industry Council (WAFIC) received funding as part of the Australian Government’s Our Marine Parks Grants Program to undertake research on the TDGDLF. This project was administered under the direction of a steering …

To assess the susceptibility of elk (Cervus canadensis) and mule deer (Odocoileus hemionus) to SARS-CoV-2, we performed experimental infections in both species. Elk did not shed infectious virus but mounted low-level serologic responses. Mule deer shed and transmitted virus and mounted pronounced serologic responses and thus could play a role in SARS-CoV-2 epidemiology.

Parallels Of Quantum Superposition In Ecological Models: From Counterintuitive Patterns To Eco-Evolutionary Interpretations Of Cryptic Species, David G. Angeler, Hannah B. Fried-Petersen
School of Natural Resources: Faculty Publications
Background Superposition, i.e. the ability of a particle (electron, photon) to occur in different states or positions simultaneously, is a hallmark in the subatomic world of quantum mechanics. Although counterintuitive at first sight, the quantum world has potential to inform macro-systems of people and nature. Using time series and spatial analysis of bird, phytoplankton and benthic invertebrate communities, this paper shows that superposition can occur analogously in redundancy analysis (RDA) frequently used by ecologists.
Results We show that within individual ecosystems single species can be associated simultaneously with different orthogonal axes in RDA models, which suggests that they operate in …

Factors Affecting Walleye And Sauger Recruitment In Lewis And Clark Lake, South Dakota, 2001–2022, William J. Radigan, Phil Chvala, Christopher Longhenry, Mark A. Pegg
School of Natural Resources: Faculty Publications
Abundance of adult walleye (Sander vitreus) and sauger (Sander canadensis), two important sport fishes, decreased significantly during 2001–2022 in Lewis and Clark Lake, a border water between Nebraska and South Dakota, despite walleye fingerling stocking and stable age-0 abundance of both species. We sought to identify factors that drove variation in age-0 abundance from 2001 to 2022 using an information theoretic approach. Age-0 walleye catch per unit effort (CPUE) was correlated to mean monthly outflow, mean annual precipitation, and mean April gauge height in a delta. Age-0 sauger CPUE was correlated to adult conspecific CPUE, mean …

A Coupled Model Of Population, Poaching, And Economic Dynamics To Assess Rhino Conservation Through Legal Trade, Henry Doyle, Kylie Champagne, Ditto Rajpal, Grace Seebeck, David J. Gerberry
Spora: A Journal of Biomathematics
Rhinoceros populations in Africa are in peril largely due to the high value of their horns and the poaching that ensues. The strategy of legalizing the international trade of rhino horn is receiving increased support among both the people and government officials in Africa. Many in the international conservation community remain opposed to the idea. The legalization strategy is straightforward in theory: legalizing the trade of rhino horn will introduce a large quantity of horn to the market, the increased supply will lead to lower prices for rhino horn, and lower prices will reduce the overall poaching pressure these animals …

If You Build It, Will They Come? Assessing Habitat Quality For Marsh Birds At Created Marshes In Southeastern Louisiana, Katherine Aylett Lipford
LSU Master's Theses
Wetland loss occurs at an alarming pace globally, with extremely high rates along the northern Gulf of Mexico. Louisiana loses a football field of wetland every 100 minutes: that is 77,000 m2 of wetland bird habitat lost daily. In Louisiana, marsh creation projects combat wetland loss, and while wildlife habitat is often used as a justification for restoration, wildlife receives little to no consideration during and after construction. Habitat characteristics such as site-specific hydrology, vegetation composition, and habitat structure affect the abundance of wetland birds and understanding these features is crucial to creating habitat that will benefit birds. My …

Fish Assemblage Structure In Great Lakes Coastal Wetlands Over Ten Years, Matthew S. Silverhart
Masters Theses
Coastal wetlands in the Laurentian Great Lakes are important habitats for many fish species. The geographic scale of the watershed and the diversity of land uses in the region result in substantial environmental variation among coastal wetlands. During 2011-2020, annual surveys were conducted as part of the Great Lakes Coastal Wetland Monitoring Program (GLCWMP) to better understand the status and trends of coastal wetlands. Fish sampling consisted of fyke netting in monodominant vegetation zones. During this time, 1225 unique monodominant plant zones in coastal wetlands were sampled, resulting in 584,125 fishes captured that consisted of 113 different species. Yellow Perch …
