Phenology Of The Invasive Balsam Woolly Adelgid, Adelges Piceae (Ratz.) (Hemiptera: Adelgidae), On Subalpine Fir In Northern Utah, Elizabeth L. Rideout Dec 2023

Phenology Of The Invasive Balsam Woolly Adelgid, Adelges Piceae (Ratz.) (Hemiptera: Adelgidae), On Subalpine Fir In Northern Utah, Elizabeth L. Rideout

All Graduate Theses and Dissertations, Fall 2023 to Present

Balsam woolly adelgid (BWA) is an invasive true fir pest in North America. Native to Europe, BWA was first discovered in Utah attacking subalpine fir in 2017. Recent BWA-caused subalpine fir mortality in northern Utah has prompted the need for baseline biological research to support pest management. Small-bodied and blending easily with its environment, BWA is a challenging pest to detect and study. Phenology, or the timing and characteristics of life stages through the year, of BWA varies depending on elevation and climate and is unstudied in Utah. This research focuses on defining aspects of BWA’s phenology, including the number …

The global COVID-19 pandemic has presented humanity with difficult and unforeseeable hurdles. Among these challenges is understanding how climate-related aspects impact the survival of the SARS-CoV-2 virus. This study aimed to investigate the relationship between environmental factors, such as temperature, humidity, and rainfall, and the spread of COVID-19 cases in different regions. A time-and-place-based ecological study design was adopted, integrating geographic information systems and statistical techniques. Statistical testing revealed a significant association between humidity (p-value = 0.000; r = -0.777) and rainfall (p-value = 0.001; r = -0.561) with COVID-19 instances. However, no statistically significant relationship was found between temperature …


Tapping Into Natural History Collections To Assess Latitudinal Gradients Of Parasite Diversity, Sebastian Botero-Cañola, Scott Lyell Gardner Jan 2023

Tapping Into Natural History Collections To Assess Latitudinal Gradients Of Parasite Diversity, Sebastian Botero-Cañola, Scott Lyell Gardner

Scott L. Gardner Publications

Parasites are key components of the biosphere not only due to their huge diversity, but also because they exert important influences on ecological processes. Nevertheless, we lack an understanding of the biogeographical patterns of parasite diversity. Here, we tap into the potential of biodiversity collections for understanding parasite biogeography. We assess species richness of supracommunities of helminth parasites infecting mammal assemblages in the Nearctic, and describe its relation to latitude, climate, host diversity, and land area. We compiled data from parasitology collections and assessed parasite diversity in Nearctic ecoregions for the entire parasite supracommunity of mammals in each ecoregion, as …
