UCSBlooms: Tracking the phenology of UCSB campus plants and using citizen science on a university campus

(2020)

Phenology is becoming more important to study with human impacts on the environment including urbanization and climate change. The UCSBlooms project is a year-long blooms tracking project that began March 11, 2019 and concluded on March 17, 2020. This project uses the University of California Santa Barbara (UCSB) citizen scientists and the citizen science program iNaturalist to track the phenology of six species of plants found on the UCSB campus. Citizen scientists are much more likely to participate in organized events rather than an open-ended project. Citizen scientists are also more likely to observe species in flower than species that are not in bloom. Non-native species have less variation in phenostages at a single date than native species. The environmental cues used to determine movement through a species’ phenology differs between families. There are many factors that affect the phenology of campus plants including urban heat islands, phylogeny, and native status. This report is the undergraduate senior thesis of the author in fulfillment for the UCSB Biological Sciences Senior Honors Program.

North Campus Open Space Restoration Project Annual Monitoring Report: Year 2 (2019)

(2020)

Born out of a vision shared by the local community, students, faculty, researchers and state and federal agencies, the North Campus Open Space (NCOS) restoration project is recreating more than 40 acres of estuarine and palustrine wetlands that historically comprised the upper portion of Devereux Slough that was filled in the mid-1960s to create the Ocean Meadows golf course. Led by the UC Santa Barbara Cheadle Center for Biodiversity and Ecological Restoration (CCBER) in collaboration with other UCSB departments, faculty, student and local community groups, contractors and government agencies, the project is also restoring more than 60 acres of upland habitats that include native grassland, coastal sage scrub, riparian, oak chaparral woodland, vernal pools and patches of annual wildflowers in clay and sandy soils. In addition to wetland and upland habitat restoration, the goals of the NCOS project include flood reduction, support for threatened and endangered species, public access and the provision of educational opportunities. Ancillary benefits of the project include carbon sequestration, preservation of local genotypes, and protection of adjacent ecological values and infrastructure through a design that integrates sea level rise considerations.

Currently in its third year of implementation, the main planting phase of the project is approximately 90% complete, and the focus is now turning towards maintenance, continued monitoring, new research projects, and supplemental planting to add diversity, including special status species such as the Ventura marsh milk-vetch (Astragalus pycnostachys var. lanosissimus). This report describes the methods and results of monitoring for the first two years of the project, from vegetation and wildlife to wetland geomorphology, hydrology and water quality, carbon sequestration studies, community use and a detailed record of restoration efforts by type of worker, task and site location. This work documents the progress of the project and supports longer-term research and monitoring programs. Results from the second year of monitoring show substantial progress towards the project’s restoration goals, with many being met or exceeded.

Aquatic Invertebrates of the Devereux Slough - 2018

(2020)

In 2018, the hardscape construction of NCOS (North Campus Open Space), a restored wetland on the Northern border of COPR (Coal Oil Point Reserve), was completed, thus approximately doubling the overall size of the wetland and offering the rather unique opportunity of being able to compare the two side-by-side.  Basic water quality and aquatic invertebrate monitoring of both sites were undertaken to better understand the dynamics of how a newly constructed wetland developed into an established wetland.

The surprising result of this first year of monitoring is that COPR and NCOS were more or less equivalent in species richness and abundance, with the Shannon-Wiener Index giving a slight nod to NCOS for more diversity and Evenness in the data.

Four taxa are the most significant contributors to the total taxa observed – Copepods, Ostracods, Cladocera, and Corixidae.  Additionally, we found Chironomids, Ceratopogonidae, Ephydridae, and Nematodes in significant abundance.

Sampling protocols were evaluated indicating that sampling in algae gives more than an order-of-magnitude greater abundance and diversity than in sampling in open water and that the Filtered Beaker method gives more precise species density information than the Sweep-Net method; when sampling at shallower depths where the Sweep-Net is not fully submerged.

Additionally, the effect on other aquatic invertebrates of the use of VectoBac for mosquito abatement was looked at – indicating a minimum, if any, affect.

Insect Collection Databasing using Symbiota

(2019)

This guide was developed at UC Santa Barbara as a general guide for how to database invertebrate zoology specimens using a Symbiota natural history collection specimen database (http://symbiota.org). The UCSB Invertebrate Zoology Collection is a small collection with taxonomic strengths in Hymenoptera and Diptera. Originally used as a teaching collection for a general entomology course taught from 1961 to 1993, this collection's diversity (9,000 insects in 21 orders and 246 families) makes it a valuable historical record of insects in endangered coastal California habitats. This report was developed as part of the Institute of Museum Library Services Grant (award #MA-30-16-0387-16) to curate and digitize the Adrian Wenner Historic Insect Collection at University of California, Santa Barbara.

The general workflow in this guide starts with images and labels of images taken and uploaded to the Symbiota database. Specimen information is transcribed directly from the images. How to create specimen image reports are also available through the Cheadle Center for Biodiversity and Ecological Restoration online eScholarship publication venue for open access publications and reports (https://escholarship.org/uc/ccber).

BugFlipper: A freeware plug-in for human assisted image processing in the GIMP

(2019)

Bugflipper is an open source plugin for the GNU Image Manipulation Program (GIMP) that performs a series of standard image correction tasks that are common when digitizing natural history collection specimens. These tasks include rotating images, color and contrast correction, reduction in overall file size, cropping, and renaming the image with a barcode number as the filename.

BugFlipper automates many of the processes based on preset values, but the program also includes a human assisted step that allows custom processing of non-standard images, quality control, and image renaming during the process. A comprehensive instruction manual for BugFlipper is included here, with troubleshooting tips and advice for modifying the plugin code to simplify a variety of human-assisted image-processing problems.

Local grassland restoration affects insect communities

(2019)

It is hypothesised that ecological restoration in grasslands can induce an alternative stable state shift in vegetation. The change in vegetation influences insect community assemblages and allows for greater functional redundancy in pollination and refuge for native insect species. 2. Insect community assemblages at eight coastal California grassland sites were evaluated. Half of these sites had undergone restoration through active revegetation of native grassland flora and half were non-restored. Insects were collected from Lupinus bicolor (Fabaceae) within 2 × 2-m2 plots in spring 2017. Lupinus bicolor is a common native species that is used in California restoration projects, and home and state landscaping projects. 3. Ordination demonstrated that insect community assemblages were different between restored and non-restored sites. These differences were seen in insect functional groups as well as taxa-specific differences and were found to be driven by environmental characteristics such as non-native forb cover. 4. Functional redundancy of herbivores decreased at restored sites, while pollinators became more redundant compared with non-restored sites. The assemblages of the common species found at restoration sites contained more native insects than those found at non-restored sites, including species such as Bombus vosnesenskii. 5. Local grassland restoration has the potential to induce an alternative stable state change and affect insect community assemblages. Additionally, it was found that grassland restoration can be a potential conservation tool to provide refugia for bumblebees (Bombus), but additional studies are required to fully understand its broader applicability.
