Analysis Of The Variables Affecting Plant Species Richness In Deserts, Eli R. Kallison, Ellen Thompson, Maddison Keen, Rusty Newman
Analysis Of The Variables Affecting Plant Species Richness In Deserts, Eli R. Kallison, Ellen Thompson, Maddison Keen, Rusty Newman
IdeaFest: Interdisciplinary Journal of Creative Works and Research from Cal Poly Humboldt
There are many hypotheses that attempt to explain patterns of species diversity in different environments. Deserts are a great place to study changes in species richness because they are relatively nutrient bare and exhibit low precipitation. This barebones environment means that slight shifts in climate and geography may lead to clear changes in species richness. We investigate how temperature, precipitation, water and light availability, latitude, elevation and other variables affect plant species richness in 20 deserts.

Habitat Assessment Of Suitable Areas For Three Rare Plant Species (Layia Carnosa, Erysimum Menziesii, And Gilia Millefoliata) In The Barr Parcel On Friends Of The Dunes Property, Sophia Grubb, Almond Dodge, Jeremy Cashen
Habitat Assessment Of Suitable Areas For Three Rare Plant Species (Layia Carnosa, Erysimum Menziesii, And Gilia Millefoliata) In The Barr Parcel On Friends Of The Dunes Property, Sophia Grubb, Almond Dodge, Jeremy Cashen
Environmental Science & Management Senior Capstones
Native rare plants are an important component of ecosystems. It is critical to preserve these species because it facilitates growth of native plants. Ecological restoration provides the necessary conditions to encourage native plant growth. Gilia millefoliata, Erysimum menziesii, and Layia carnosa are three rare plants found on the Friends of the Dunes property in Arcata, CA. In this assessment, we surveyed these three rare plants and came up with a management plan for the Barr Parcel on the Friends of the Dunes property. Friends of the Dunes recently acquired the Barr Parcel and are waiting for restoration permits …
Exploring The Origins Of Secondary Growth – Two Lower Devonian (Emsian) Euphyllophytes From Gaspé, Canada, And Their Implications For The Evolution Of Secondary Growth, Kelly C. Pfeiler
Cal Poly Humboldt theses and projects
Secondary growth from a vascular cambium has a deep fossil record among euphyllophytes, with the earliest occurrence dated to 407 Ma. To date, Armoricaphyton and Franhueberia represent the only instances of secondary growth formally documented in the Early Devonian. Secondary growth diversified rapidly and was present in all major euphyllophyte lineages by the Middle Devonian. Here, I describe two new Early Devonian euphyllophytes exhibiting secondary growth, from the Emsian (c. 400-395 Ma) Battery Point Formation (Québec, Canada): Gmujij tetraxylopteroides gen. et sp. nov. and Perplexa praestigians gen et sp. nov. Both these plants possess mesarch actinosteles with Psilophyton-type …
The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler
The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler
Cal Poly Humboldt theses and projects
Early successional wetland habitat is being lost in temperate regions worldwide as a result of changes in disturbance regimes that allow for the establishment and dominance of woody species. In particular, this phenomenon is pronounced in fens, which harbor high numbers of rare herbaceous species that require early successional habitat. I investigated the relationship between woody vegetation encroachment and herbaceous species diversity within a Northern California coastal fen that has been undergoing encroachment by woody vegetation for ca. 80 years by recording species richness and cover data from 338 permanent plots throughout the fen. I also investigated the effect of …
