Status Of The Blackstripe (Fundulus Notatus) And Blackspotted (F. Olivaceus) Topminnows In The Ozark Uplands Of Central Missouri, 2020 The Ohio State University
Status Of The Blackstripe (Fundulus Notatus) And Blackspotted (F. Olivaceus) Topminnows In The Ozark Uplands Of Central Missouri, Nathaniel Steffensmeier, Naznin Sultana Remex, Robert Hrabik, David D. Duvernell
Southeastern Fishes Council Proceedings
The topminnow species Fundulus notatus and F. olivaceus have broadly overlapping geographic distributions that extend throughout much of the central and southern United States. In the northern portion of their respective ranges, in Missouri, the regional distributions of the two species coincide largely with recognized ecoregions. In the unglaciated southern half of Missouri, F. olivaceus is distributed throughout Ozark upland habitats while F. notatus is abundant in marginal large river and prairie habitats along the Ozark borders. An exception to this partitioning is the historical report of abundant F. notatus in the Bourbeuse and upper Meramec River drainages within the ...

A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, 2020 The University of San Francisco
A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle
Master's Projects and Capstones
Wildfires in the mixed conifer forests of California’s Sierra Nevada have been a common and natural disturbance for thousands of years, historically occurring every 3 to 30 years. The flora and fauna of the mixed conifer forest have evolved to depend on low to moderate severity wildfires for reproduction, foraging, and habitat. However, the Sierra Nevada has experienced dramatic environmental changes over the past ~150 years as a result of three main factors: wildfire suppression, climate change, and habitat loss. Because of the threat wildfires pose to human lives, property and timber harvest, they have been suppressed to an ...

Influences Of Anti-Bd Bacteria On Amphibians And Their Microbiomes, 2020 University of South Dakota
Influences Of Anti-Bd Bacteria On Amphibians And Their Microbiomes, Emme L. Schmidt
The fungal pathogen Batrochochytrium dendrobatidis (Bd) has been threatening amphibian populations across the globe. Recent work has discovered that bacteria isolated from certain populations of amphibians protect hosts from this pathogen. This project focuses on the anti-fungal mechanisms of Serratia marcescens, a species of bacteria isolated from a Costa Rican frog that dramatically inhibited Bd in culture. Wild-type and recombinant S. marcescens was introduced to the microbiomes of a live amphibian host, Acris blanchardi (Blanchard’s Cricket Frog) and then challenged with Bd to examine the protective effects of this bacteria. The experiment includes recombinant S. marcescens with the genetic ...
When Water Isn't Wet: The Evolution Of Water Right Mitigation In Washington State, 2020 Seattle University School of Law
When Water Isn't Wet: The Evolution Of Water Right Mitigation In Washington State, Rachael Osborn, Michael Mayer
Seattle Journal of Technology, Environmental & Innovation Law
What is water right mitigation?
The allocation of surface and ground water resources for out of stream uses via the western water rights doctrine of prior appropriation comes with serious environmental consequences – depletion of streamflow and aquifers. Over-appropriation by water rights has led to deleterious impacts on natural resources, including salmon survival, water quality, and public uses of state waterways.
Because of the over-appropriated condition of Washington’s rivers and aquifers, the issuance of new water rights has until recently required water-for-water or in-kind mitigation, with the goal to directly compensate for deleterious impacts. Historically, the Water Resources Program of ...
Another New Species Of Euscorpius Thorell, 1876 From The Caves Of Croatia And Bosnia-Herzegovina (Scorpiones: Euscorpiidae), With Notes On Biogeography And Cave Ecology, Gioele Tropea, Roman Ozimec
Another new, subtroglophile scorpion species is described from Croatia, Euscorpius biokovensis sp. n. It is morphologically and ecologically similar to E. feti Tropea, 2013 but can be distinguished from the latter by a lower number of trichobothria (Pv = 8–9, with mostly 8, and usually et = 6) and pectinal teeth (usually Dp = 7 in males and 6 in females). The new species also has a more northern distribution although in some areas the two species overlap. E. biokovensis sp. n. has been found in more than 20 caves in Croatia, which makes it the most common Euscorpius species found in ...
A Contribution To The Macrofungi Of Cloudland Canyon State Park, 2020 University of Tennessee at Chattanooga
A Contribution To The Macrofungi Of Cloudland Canyon State Park, Peyden Valentine
I conducted a survey of the macroscopic fungi within Cloudland Canyon State Park, Dade County, GA that consisted of twenty-three forays from May through December of 2019, and one foray in March 2020. The results of my survey add baseline data to our knowledge of the mushrooms present within the park, allow for the future construction of an All Taxa Biodiversity Index, and allow comparisons to other surveys of fungal diversity in similar areas of the Cumberland Plateau: the Tennessee River Gorge Trust (Starrett 2005), and the Lula Lake Land Trust (De Guzman 2000). My survey resulted in an overall ...

Investigating The Effects Of Temperature On Lesser Celandine, Regina Bellian
The Downtown Review
This paper explores invasive species Ficaria verna (Lesser celandine) and the effects of temperature on its growth. Trials were completed with two treatments, 13OC cold temperature and 20OC ambient temperature. Germinated bulbils of Lesser celandine were planted on February 15, 2017 and placed in their respective growing chambers. The plants were watered weekly and monitored for growth until harvest on March 29, 2017. Upon harvest, the plants’ height, largest leaf diameter and biomass were measured after extraction from soil and the removal of the leftover soil debris. Average height was found to be 11.66cm for the cold treatment and ...

A Basic Ddradseq Two‐Enzyme Protocol Performs Well With Herbarium And Silica‐Dried Tissues Across Four Genera, Ingrid E. Jordon-Thaden, James B. Beck, Catherine A. Rushworth, Michael D. Windham, Nicolas Diaz, Jason T. Cantley, Christopher T. Martine, Carl J. Rothfels
Faculty Journal Articles
The ability to sequence genome‐scale data from herbarium specimens would allow for the economical development of data sets with broad taxonomic and geographic sampling that would otherwise not be possible. Here, we evaluate the utility of a basic double‐digest restriction site–associated DNA sequencing (ddRADseq) protocol using DNAs from four genera extracted from both silica‐dried and herbarium tissue.
DNAs from Draba, Boechera, Solidago, and Ilex were processed with a ddRADseq protocol. The effects of DNA degradation, taxon, and specimen age were assessed.
Although taxon, preservation method, and specimen age affected data recovery, large phylogenetically ...
194— Plant Diversity & Allergies, 2020 SUNY Geneseo
194— Plant Diversity & Allergies, Catherine Kilada
The impact of industrialization and its resulting decline in biodiversity may be a contributing factor to the rapidly increasing prevalence of allergies across the United States. This decline in biodiversity reduces the contact between people and various tree species, causing an increase in the number of individuals who experience moderate to severe allergies. I predict there may be a correlation between myriad allergies and geographic location within New York State. Using an online survey distributed to the Geneseo Student Body, I will determine if there are certain areas of New York State that have higher reports of certain allergy types ...
135— Coral-Sponge Interactions On Rocky Point Reef, San Salvador, Bahamas, 2020 SUNY Geneseo
135— Coral-Sponge Interactions On Rocky Point Reef, San Salvador, Bahamas, Michael Harvey, Anna Meichenbaum, Brooke Stickles
We surveyed the intensity of competition for reef space between sponges and corals at the Rocky Point patch reef adjacent to San Salvador Island, The Bahamas. Our working hypothesis was that, because of a dearth of predators, fast growing, chemically unprotected sponges more likely to be involved in competitive interactions. Results indicate that competition for reef space was widespread, but contrary to our hypothesis no sponge or coral species was disproportionately more involved in these interactions. These results contradict previous studies on Rocky Point reef and in our discussion we propose an explanation for this discrepancy.

Broad Host Range Of Sars-Cov-2 Predicted By Comparative And Structural Analysis Of Ace2 In Vertebrates, Joana Damas, Elinor K. Karlsson, Harris A. Lewin
University of Massachusetts Medical School Faculty Publications
The novel coronavirus SARS-CoV-2 is the cause of Coronavirus Disease-2019 (COVID-19). The main receptor of SARS-CoV-2, angiotensin I converting enzyme 2 (ACE2), is now undergoing extensive scrutiny to understand the routes of transmission and sensitivity in different species. Here, we utilized a unique dataset of 410 vertebrates, including 252 mammals, to study cross-species conservation of ACE2 and its likelihood to function as a SARS-CoV-2 receptor. We designed a five-category ranking score based on the conservation properties of 25 amino acids important for the binding between receptor and virus, classifying all species from very high to very low. Only mammals fell ...
Environmental Dna Metabarcoding Detects Mammal Use Of Stock Tanks And Natural Springs On The Prescott National Forest, 2020 Montana State University - Billings
Environmental Dna Metabarcoding Detects Mammal Use Of Stock Tanks And Natural Springs On The Prescott National Forest, K. A. Smith, Berenice Carreras Mendiolea, C. E. Benson, F. B. Anaya
Discovery Day - Prescott
Recent research has shown the viability of environmental DNA (eDNA) analysis as a tool for identifying species presence in aquatic ecosystems. However, there is limited research indicating the feasibility of eDNA as a survey tool in water sources such as springs and stock tanks. Because of the scarcity of water in the high desert landscape of Arizona, natural springs and stock tanks are an important water resource. In this study, we examined whether 16S rRNA metabarcoding could detect mammal eDNA in springs and stock tanks in the Prescott National Forest. During summer 2019, we collected and analyzed water samples at ...

Scorpion Predation In Cuba: New Cases And A Review, Tomás M. Rodríguez-Cabrera,, Rolando Teruel, Ernesto Morell Savall
The ecology of Cuban scorpions is very insufficiently studied and the scarce existing information on their natural enemies is dispersed in the literature. However, scorpions in general are well known to play an important role both as predators and prey in natural ecosystems. Herein we present new instances of predation on different species of scorpions in Cuba, and a review on the topic
Grackles, 2020 USDA APHIS Wildlife Services
Grackles, Michael J. Bodenchuk, David L. Bergman
Wildlife Damage Management Technical Series
Numbering in the tens of millions of birds, grackle populations in North America can cause a variety of conflicts with people. Grackles eat agricultural crops and livestock feed, damage property, spread pathogens, and collide with aircraft. Their large roosts can be a nuisance in urban and suburban areas. A combination of dispersal techniques, exclusion, and lethal removal may help to reduce grackle damage.
Grackles adapt easily to human-dominated environments, and exploit human food and other features of human landscapes. Thus, an integrated damage management approach to grackle damage focuses on reducing and eliminating the damage, rather than simply controlling grackle ...
