Bryophytes At Cave Entrances Across A Range Of Anthropogenic Disturbance, Morghan Mccool
Bryophytes At Cave Entrances Across A Range Of Anthropogenic Disturbance, Morghan Mccool
2023 Midwest Ecology & Evolution Conference
Cave entrances are critical ecosystems in their role as ecotones between the interior cave environment and the surrounding external environment. Bryophytes serve as ecosystem engineers of cave entrance microhabitats. This study piloted a method to quantify anthropogenic disturbance unique to cave entrances and characterize the bryophyte assemblages at caves in urban and other natural areas. Bryophytes and environmental variables were sampled from cave entrances; bryophytes were identified, alpha and beta diversity values were computed. So far, 144 species of bryophytes, 36 of which were state records, have been identified across 6 sites. By improving knowledge of bryophyte communities, park managers …
Discovery Of Epiphytic Lichens In Connecticut Suggests Novel Introduction And Reintroduction Via Horticultural Practices, Henry A. Frye, Zachary Muscavitch, Bernard Goffinet
Discovery Of Epiphytic Lichens In Connecticut Suggests Novel Introduction And Reintroduction Via Horticultural Practices, Henry A. Frye, Zachary Muscavitch, Bernard Goffinet
EEB Articles
The discovery of Teloschistes chrysophthalmus in Connecticut more than one hundred years since its last known occurrence is argued to result from human introduction. The species only occurred on the horticultural tree, Gleditsia triacanthos var. inermis, planted on the University of Connecticut campus. Gleditsia triacanthos is not indigenous to northeastern North America, but is widespread in the central United States. Other epiphytic macrolichens also recorded on this phorophyte include Punctelia bolliana and Parmotrema austrosinense, both widespread in the central United States, and new to Connecticut and New England, respectively. This is likely the first reported case of combined …
Spatio-Temporal Dynamics Of Fungal Communities And Their Effects On Plants, Kel Cook
Spatio-Temporal Dynamics Of Fungal Communities And Their Effects On Plants, Kel Cook
Biology ETDs
Fungi perform several critical functions in the environment. Spatiotemporal distributions of fungal communities will mediate when and where these functions happen and how they vary across the landscape. I first explored tropical tree canopy fungal community variation at small spatial scales and documented near total turnover of fungi across sub-meter distances and among adjacent substrates. The second chapter analyzed fungal turnover over the course of three years, where community stability was driven primarily by abundant fungi. In the third chapter, I tested effects of the environment, including host plant and habitat, on canopy fungal communities and found only small effects, …
Impacts Of Rock Climbing On Lichen And Bryophyte Cliff Communities In The Arid West, Giovanna M. Bishop
Impacts Of Rock Climbing On Lichen And Bryophyte Cliff Communities In The Arid West, Giovanna M. Bishop
2020 Symposium Posters
Lichens and bryophytes make up the majority of the diversity and cover in cliff systems around the world. Recently, with the rapid rise of rock climbing, there are concerns rock climbers are negatively impacting cliff communities. My study will compare climbed and unclimbed granite cliffs to better understand the impacts of rock climbing on lichen and bryophyte diversity and cover in eastern Washington. The objectives of this study are to assess the impacts of rock climbing on lichen and bryophyte cliff community diversity and cover and improve route development and cliff management practices for lichens and bryophytes. This study will …
