Pinpointing Dream Settings Onto Place Cookies
Pinpointing Dream Settings Onto Place Cookies
The International Journal of Ecopsychology (IJE)
Dream reports are short pieces of text, where a dreamer summarizes the remembered experience of nightly dreams. Dream cartography addresses especially the spatial information contained in dream reports. In this context, the current formalization of space in GIScience such as points, lines, polygons, or labels, including place names or addresses, is not sufficient for mapping dream settings. In the best case, dream reports mention place names or streets. However, usually, the perception of space in dreams is designated in terms of whether this is familiar or not, inside or outside, safe or threatening. Moreover, basic comparisons between dream settings are …
Evaluating Benthic Macroinvertebrate Populations In Response To Scouring Events In The Trinity River, Ca, Liam Hay, Michael W. O'Neil, Chloe Pieper-Wasem
Evaluating Benthic Macroinvertebrate Populations In Response To Scouring Events In The Trinity River, Ca, Liam Hay, Michael W. O'Neil, Chloe Pieper-Wasem
Environmental Science & Management Senior Capstones
River systems across California have been impacted by appurtenant structures such as dams and diversions. These structures have had an adverse impact on Benthic invertebrate (BMI) communities by regulating river systems and changing the natural hydraulic pulses that follow seasonal precipitation. Benthic invertebrates are a critical food resource for salmonids and serve as an indicator of ecosystem health. Our study was interested in seeing the effects of scouring events on BMI in the Trinity River of Trinity County, C.A. Following a large precipitation event that occurred in the region in December 2022, an influx of water entered the river through …
Carnivore And Ungulate Occurrence In A Fire-Prone Region, Sara J. Moriarty-Graves
Carnivore And Ungulate Occurrence In A Fire-Prone Region, Sara J. Moriarty-Graves
Cal Poly Humboldt theses and projects
Increasing fire size and severity in the western United States causes changes to ecosystems, species’ habitat use, and interspecific interactions. Wide-ranging carnivore and ungulate mammalian species and their interactions may be influenced by an increase in fire activity in northern California. Depending on the fire characteristics, ungulates may benefit from burned habitat due to an increase in forage availability, while carnivore species may be differentially impacted, but ultimately driven by bottom-up processes from a shift in prey availability. I used a three-step approach to estimate the single-species occupancy of four large mammal species: mountain lion (Puma concolor), coyote …
Merging Art And Science: Lessons Learned From An 'Otterly' Different Case Study, Jess Barger
Merging Art And Science: Lessons Learned From An 'Otterly' Different Case Study, Jess Barger
Cal Poly Humboldt theses and projects
Environmental art projects use artistic interpretation to tell stories about the natural world, often with the hope that they will inspire awareness or behavioral change. In 2019, an art project to raise awareness about North American river otters (Lontra canadensis) was launched in Northern California, using over 100 river otter sculptures painted and decorated by local artists. Through a mixed-methods approach, I quantified the initial outcomes of the project, North Coast Otters, as well as the response to the project by the public on social media as a case study in environmental art and outreach. Participating artists’ interviews and …

Exploring Community Knowledge And Perceptions Of Flooding And Sea-Level Rise In King Salmon, California, Kristina Kunkel
Exploring Community Knowledge And Perceptions Of Flooding And Sea-Level Rise In King Salmon, California, Kristina Kunkel
Cal Poly Humboldt theses and projects
The coastal community of King Salmon, California could be at the highest risk of relative sea-level rise on the entire U.S. West Coast. In 2019, the community already experiences severe flooding at least annually and may be regularly inundated as early as 2050. Until this study, there had been no documented effort to reach out to the community to show them future sea-level rise projections, understand the context of life in King Salmon, and listen to their reactions and perceptions. This research utilized a mixed methods grounded theory approach integrating semi-structured interviews with King Salmon stakeholders, qualitative data analysis, public …
Low Income Housing Energy Efficiency Improvement Program For The Yurok Tribe Of Northern California, Keivan Branson
Low Income Housing Energy Efficiency Improvement Program For The Yurok Tribe Of Northern California, Keivan Branson
Cal Poly Humboldt theses and projects
Housing on the Yurok reservation in California is a major concern for the local Tribal Government. This report details a study of the energy situation for housing of the Yurok Tribe to provide a framework for implementing housing energy efficiency to benefit low-income members of the Tribal community residing in substandard housing. The report briefly details the history of the reservation as it pertains to the current housing situation, as well as the authors personal context of living for 16 years in the reservation town of Klamath, CA. The analysis draws on information obtained from mixed methods, including information collected …
Post-Fire Regeneration And Fuel Succession Patterns In Hesperocyparis Bakeri Forests, Bret Anthony Mcnamara
Post-Fire Regeneration And Fuel Succession Patterns In Hesperocyparis Bakeri Forests, Bret Anthony Mcnamara
Cal Poly Humboldt theses and projects
Climate change is predicted to cause widespread redistribution of suitable tree habitats, as well as increase the size and frequency of wildfires in the western United States during the forthcoming century. Rare serotinous conifers may have heightened sensitivity to the impacts of both fire regime and climate shifts for multiple reasons. First, the rapid spatial rearrangement of suitable habitat will disproportionately affect trees with constrained seed dispersal capabilities, and limited dispersal is a trait associated with some genera of serotinous trees. Second, a number of serotinous conifers depend on fire disturbances for regeneration, though with the expected increase in annual …
Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez
Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez
Cal Poly Humboldt theses and projects
The conservation and recovery of anadromous salmonids (Oncorhynchus sp.) depend on stream restoration and protection of freshwater habitats. In-stream large wood dictates channel morphology, increases retention of terrestrial inputs such as organic matter, nutrients and sediment, and enhances the quality of fish habitat. Historic land use/land cover changes have resulted in aquatic systems devoid of large wood. Restoration by placement of large wood jams is intended to restore physical and biological processes. An important question for scientists and restoration managers, in addition to the initial effectiveness of restoration, is the persistence and fate of large wood installations. In this …
Assessing Spatio-Temporal Patterns Of Forest Decline Across A Diverse Landscape In The Klamath Mountains Using A 28-Year Landsat Time-Series Analysis, Drew S. Bost
Cal Poly Humboldt theses and projects
Rates of tree mortality in California and the Pacific Northwest have greatly increased in recent years, driven largely by pest and pathogen outbreaks as well as the effects of hotter, warmer droughts. While there have been a multitude of regional-scale assessments of mortality and forest decline, landscape-level studies are necessary to better identify forests that are most vulnerable to decline and to anticipate future changes. This need is particularly notable in the remote and little-studied mountains of northwest California, which are renowned for their diverse, heterogeneous vegetation types. A recent observation of elevated levels of Shasta red fir (Abies …
Multiscale Habitat Suitability Modeling For Canary Rockfish (Sebastes Pinniger) Along The Northern California Coast, Portia N. Saucedo
Multiscale Habitat Suitability Modeling For Canary Rockfish (Sebastes Pinniger) Along The Northern California Coast, Portia N. Saucedo
Cal Poly Humboldt theses and projects
Detailed spatially-explicit data of the potential habitat of commercially important rockfish species are a critical component for the purposes of marine conservation, evaluation, and planning. Predictive habitat modeling techniques are widely used to identify suitable habitat in un-surveyed regions. This study elucidates the predicted distribution of canary rockfish (Sebastes pinniger) along the largely un-surveyed northern California coast using data from visual underwater surveys and predictive terrain complexity covariates. I used Maximum Entropy (MaxEnt) modelling software to identify regions of suitable habitat for S. pinniger greater than nine cm in total length at two spatial scales. The results of …
