The purpose of this investigation was to assess the day-to-day and week-to-week reliability of body fat (BF%) measurements using three different methods [air displacement plethysmography (Bod Pod), bioelectrical impedance analysis (Fitbit Aria®), and . . .

Phyllaplysia taylori, a sea hare found in eelgrass beds along the Pacific coast, is an integral part of eelgrass ecosystems. Temperatures and salinities in San Francisco Bay are highly variable and expected to shift with continued climate change. Phyl . . .

The alphaproteobacterium Sinorhizobium meliloti colonizes the roots of host plants, such as Medicago species, and induces the formation of nodules, where it fixes molecular nitrogen in exchange for carbon compounds. A previous suppressor analysis had . . .

Pelagic ecosystem links are typically studied separately with predator response often invoked from climate change, while intermediary alteration in nutrients and plankton production are inferred as the root cause. More specifically, we explored how Pa . . .

Sea urchins (Echinoidea) comprise a group exhibiting enormous diversity in shape and size. At the lowest end of the size scale is Echinocyamus, a poorly known genus of highly miniaturized relatives of the sand dollars sometimes called “sea peas.” Ther . . .

A northern California strain of Pseudo-nitzschia australis was examined using nonaxenic, batch cultures to examine the effects of more acidic conditions (reduced pH due to increased pCO2) on the growth, photosynthesis, and domoic acid production of th . . .

The Astronieae represent one of the earliest diverging clades of the pantropical family Melastomataceae and are endemic to the rainforests of southeast Asia and the Pacific islands. They comprise about 150 species of trees and shrubs in four currently . . .

This research takes an innovative approach to modeling distribution of a marine predator explicitly in the temporal domain. Harbor porpoise (Phocoena phocoena) are a small cetacean seen in San Francisco Bay year round. Porpoise presence at the entranc . . .

There is an atypical distribution of the non-native crab Carcinus maenas, rarely found at high elevations in the intertidal zone elsewhere but mainly located in high elevation habitats in San Francisco Bay. Perceived threat from subtidal predators at . . .

A two-part study was carried out examining population genetics and fusion behavior of an invasive colonial ascidian, Didemnum vexillum. A barcoding mitochondrial gene, COI, was used in previous studies at global and regional levels to assess the nativ . . .
