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 . . .

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 . . .

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 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 . . .

Nitrogen is an essential nutrient that is inaccessible to many organisms in its abundant atmospheric form. Rhizobia, a group of bacteria capable of fixing molecular dinitrogen into more useful forms, symbiotically colonize the root nodules of legumino . . .

Introduced species often disrupt established food webs, but some native predators can come to rely on introduced prey. Understanding the net effects of the non-natives on imperiled predators is crucial for planning conservation measures. The invasive . . .

The family Tritoniidae (Nudibranchia, Cladobranchia, Dendronotidae) is a cryptic group of nudibranchs known to feed on a variety of octocorals (Mcdonald and Nybakken, 1999). The family has a muddled evolutionary history and previously has had limited . . .

Selective feeding by copepods has important ecological implications such as food web length, nutrient limitation, and control of algal blooms. Traditional methods for investigating copepod feeding in natural waters (e.g. stable isotope and fatty acid . . .

Salmonella, consisting of more than 2000 serovars, is the second most common cause of foodborne illness in the US that can survival intracellularly and lead to gastrointestinal illness. Phosphorothioation (PT) is a post-replicative modification that r . . .

The geographical history of the Gulf of Guinea Islands has played a significant role in shaping the diversity and distributional patterns of the Hemidactylus geckos in the African- Atlantic clade. This study elucidates the phylogenetic relationships b . . .
