Pervasive Iron Limitation At Subsurface Chlorophyll Maxima Of The California Current, Shane L. Hogle, Christopher L. Dupont, Brian M. Hopkinson, Andrew L. King, Kristen N. Buck, Kelly L. Roe, Rhona K. Stuart, Andrew E. Allen, Elizabeth L. Mann, Zackary I. Johnson, Katherine A. Barbeau

Kristen N. Buck

Subsurface chlorophyll maximum layers (SCMLs) are nearly ubiquitous in stratified water columns and exist at horizontal scales ranging from the submesoscale to the extent of oligotrophic gyres. These layers of heightened chlorophyll and/or phytoplankton concentrations are generally thought to be a consequence of a balance between light energy from above and a limiting nutrient flux from below, typically nitrate (NO3). Here we present multiple lines of evidence demonstrating that iron (Fe) limits or with light colimits phytoplankton communities in SCMLs along a primary productivity gradient from coastal to oligotrophic offshore waters in the southern California Current ecosystem. SCML ...


Monitoring Desert Ungulates Via Fecal Dna-Based Capture Recapture, Stephen S. Pfeiler May 2019

Monitoring Desert Ungulates Via Fecal Dna-Based Capture Recapture, Stephen S. Pfeiler

All Graduate Theses and Dissertations

Estimates of population abundance and survival are critical for effective wildlife management. Obtaining estimates of these kind using traditional wildlife monitoring techniques (i.e. ground and aerial surveys) has proven to be difficult, especially for species that are wide ranging and exist in small, patchily distributed populations.

My objective was to implement fecal DNA-based capture-recapture surveys to estimate abundance and survival of two different ungulate populations that inhabit the deserts of southeastern California. I also compared fecal DNA-based capture-recapture techniques to traditional methods by evaluating the costs and precision associated with both methods. Using artificial water sources as focal sampling ...


Decades Of Native Bee Biodiversity Surveys At Pinnacles National Park Highlight The Importance Of Monitoring Natural Areas Over Time, Joan M. Meiners, Terry L. Griswold, Olivia Messinger Carril Apr 2019

Decades Of Native Bee Biodiversity Surveys At Pinnacles National Park Highlight The Importance Of Monitoring Natural Areas Over Time, Joan M. Meiners, Terry L. Griswold, Olivia Messinger Carril

Terry Griswold

Thousands of species of bees are in global decline, yet research addressing the ecology and status of these wild pollinators lags far behind work being done to address similar impacts on the managed honey bee. This knowledge gap is especially glaring in natural areas, despite knowledge that protected habitats harbor and export diverse bee communities into nearby croplands where their pollination services have been valued at over $3 billion per year. Surrounded by ranches and farmlands, Pinnacles National Park in the Inner South Coast Range of California contains intact Mediterranean chaparral shrubland. This habitat type is among the most valuable ...


Metrics For Understanding Large-Scale Controls Of Multivariate Temperature And Precipitation Variability, John P. O'Brien, Travis A. O'Brien, Christina M. Patricola, S.-Y. Simon Wang Apr 2019

Metrics For Understanding Large-Scale Controls Of Multivariate Temperature And Precipitation Variability, John P. O'Brien, Travis A. O'Brien, Christina M. Patricola, S.-Y. Simon Wang

Plants, Soils, and Climate Faculty Publications

Two or more spatio-temporally co-located meteorological/climatological extremes (co-occurring extremes) place far greater stress on human and ecological systems than any single extreme could. This was observed during the California drought of 2011–2015 where multiple years of negative precipitation anomalies occurred simultaneously with positive temperature anomalies resulting in California’s worst drought on observational record. The large-scale drivers which modulate the occurrence of extremes in two or more variables remains largely unexplored. Using California wintertime (November–April) temperature and precipitation as a case study, we apply a novel, nonparametric conditional probability distribution method that allows for evaluation of complex ...


The Impacts Of Episodic Floods, Droughts, Turbidites On Organic Carbon Burial Over The Past 2,000 Years In The Santa Barbara Basin, California, Caitlyn Sarno Apr 2019

The Impacts Of Episodic Floods, Droughts, Turbidites On Organic Carbon Burial Over The Past 2,000 Years In The Santa Barbara Basin, California, Caitlyn Sarno

Theses and Dissertations

Over the past several millennia, Southern California has experienced episodic climate that have influenced the magnitude and composition of terrestrial and marine material that ultimately reaches ocean sediments. Here, we analyze elemental concentrations, stable isotopes, and n-alkane lipids as tracers of terrestrial and marine sources in drought, turbidite, and flood horizons from a well-dated sediment core in the Santa Barbara Basin (SBB) that spans the last 2,000 years. Stable isotopes (δ13C and δ15N), indicate that more terrestrial organic carbon (OC) input occurred during floods relative to non-event periods, while bulk C/N ratios remained relatively constant (~10). Long chain ...


2016 - California Land Use And Management - A Resource Management Strategy Of The California Water Plan Mar 2019

2016 - California Land Use And Management - A Resource Management Strategy Of The California Water Plan

Miscellaneous Documents and Reports

Land use planning and management cuts across many resource management strategies. More efficient and effective land use is linked to several resource management strategies including watershed, water use efficiency, groundwater quality, flood management, parks and recreation, climate change adaptive management and agricultural lands stewardship. Directly development away from agricultural lands permits multi-objective management of these lands for agricultural preservation, floodplain management, water quality, habitat conservation, and sustainable development. In addition, planning for more compact and sustainable communities, both urban and rural, will assist in reducing reliance on the state-s water supply, and result in more efficient use of California’s ...


Mass Stranding Of Marine Birds Caused By A Surfactant-Producing Red Tide., David A. Jessup, Melissa A. Miller, John P. Ryan, Hannah M Nevins, Heather A. Kerkering, Abdou Mekebri, David B. Crane, Tyler A. Johnson, Raphael M. Kudela Feb 2019

Mass Stranding Of Marine Birds Caused By A Surfactant-Producing Red Tide., David A. Jessup, Melissa A. Miller, John P. Ryan, Hannah M Nevins, Heather A. Kerkering, Abdou Mekebri, David B. Crane, Tyler A. Johnson, Raphael M. Kudela

Tyler Johnson

In November-December 2007 a widespread seabird mortality event occurred in Monterey Bay, California, USA, coincident with a massive red tide caused by the dinoflagellate Akashiwo sanguinea. Affected birds had a slimy yellow-green material on their feathers, which were saturated with water, and they were severely hypothermic. We determined that foam containing surfactant-like proteins, derived from organic matter of the red tide, coated their feathers and neutralized natural water repellency and insulation. No evidence of exposure to petroleum or other oils or biotoxins were found. This is the first documented case of its kind, but previous similar events may have gone ...

Miscellaneous Documents and Reports

The water available for irrigation and domestic supply was the chief factor in the development of southern California, which then had a population of more than 1,000,000 people. The many mountain streams of California afforded abundant hydroelectric power, the utilization of which in manufacturing enterprises and in transportation had been made possible by the progress of electric-power transmission during the previous decade.

Information concerning the quantity of water carried by the streams had been and would continue to be an important factor in the development of these resources, for the fundamental importance of stream-flow data was so thoroughly ...
