A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin D. Purdy Jan 2025

A Flora Of Coyote Ridge And Flat, Inyo County, California, Martin D. Purdy

Aliso: A Journal of Systematic and Floristic Botany

California’s Sierra Nevada contains a disproportionate share of the state’s plant diversity and is one of the most floristically diverse regions of its size in the United States. The high Sierra Nevada, in particular, has been identified as an important center of species richness and endemism within the State. Anthropogenic climate warming is expected to disproportionately affect mountain ecosystems, and models have predicted habitat contraction and extirpation for many alpine plant taxa. A specimen-based inventory of the vascular plants and bryophytes of Coyote Ridge and Flat was conducted to establish baseline data for one such sensitive alpine and subalpine area. …


Bryophyte Ecosystem Services: How Bryophytes Impact Ecosystem Processes And Their Use In Urban Systems, Keila Spangler Jun 2021

Bryophyte Ecosystem Services: How Bryophytes Impact Ecosystem Processes And Their Use In Urban Systems, Keila Spangler

University Honors Theses

Bryophytes, which include mosses, liverworts, and hornworts, are non-vascular plants that provide crucial ecosystem services in natural and urban systems. In natural systems, these services include carbon, water, and nutrient cycling and maintenance of community level biodiversity. In urban systems, bryophytes can be used as green roof substrate, as bioindicators to monitor pollution and air quality, for horticulture uses, and in medicine. Although bryophytes possess some qualities, such as reproduction by spores, that may give them an advantage compared to vascular plants as the climate warms, their response to climate change remains understudied. This paper will review the literature on …


Impacts Of Rock Climbing On Lichen And Bryophyte Cliff Communities In The Arid West, Giovanna M. Bishop Jan 2020

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 Jan 2019

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 …
