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 …
Checklist Of Mosses Of Oregon, 2022, John Christy, David H. Wagner, David Kofranek
Checklist Of Mosses Of Oregon, 2022, John Christy, David H. Wagner, David Kofranek
Institute for Natural Resources Publications
This list is based on Christy et al. (1982) and supersedes any online versions posted prior to the date shown above. Additions to the flora since 1982 are marked by asterisks, with the earliest known verified sources noted in square brackets. Unless noted otherwise, nomenclature conforms to Flora of North America Volumes 27 and 28. Most family placements follow Goffinet et al. 2014. For convenience, synonyms used by Lawton (1971) and more recent works are provided in square brackets. In general, sources for nomenclatural changes can be found in the TROPICOS database. The checklist is followed by annotated lists of …
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 …
Relative Competitive Abilities, Intersexual Overyielding, And Population Sex Ratio Changes In A Bryophyte, Zachary Stanley
Relative Competitive Abilities, Intersexual Overyielding, And Population Sex Ratio Changes In A Bryophyte, Zachary Stanley
Theses and Dissertations--Biology
Unequal sex ratios are widespread in dioecious plants and understanding their cause is important to understanding fundamental aspects of their population dynamics, and yet what causes biased sex ratios in plants is still poorly understood. Competition experiments have been used in plants to predict the outcome of species interactions, but they have rarely been used to help explain sex ratio bias. This study used a response surface competition design to measure the relative competitive abilities of the sexes of the bryophyte Marchantia inflexa (a thallus liverwort of Marchantiaceae) to predict the outcome of competition before the onset of sexual reproductive …
