Productivity Measurements

Bacterioplankton productivity measurements based on [methyl-3H]-thymidine (TdR) or L-[3,4,5-3H]leucine (L-leu) incorporation typically depend on cold trichloroacetic acid (TCA) precipitation to separate 3H uptake from incorporation. An additional rinse with cold 80% ethanol (EtOH) removed an average of 22 (L-leu) and 32% (TdR) of 3H "incorporated" by San Francisco Bay samples and decreased the between-duplicate difference by a factor of 3.5. Similar results were obtained with samples from Tomales Bay, Calif., and Palmer Station, Antarctica. Varying amounts of cold TCA insoluble radiolabel from six other substrates were removed by the EtOH rinse. Regression analysis showed relationships between the effect of the EtOH rinse and a group of environmental variables and derived parameters. The percentage of 3H removed was generally independent of filter type; however, there were often large differences in the amount of 3H retained by Millipore versus Nuclepore or Poretics filters. The results strongly suggest that an EtOH rinse or other organic extraction should be included in protocols to determine incorporation of radiolabeled substrates into macromolecules. Furthermore, sequestering low molecular weight substrates in some sort of lipid-bound pool may represent a general storage mechanism employed by bacterioplankton. Key words: bacterioplankton, production, San Francisco Bay, filtration, incorporation.

Drag Queens

Researchers and practitioners have much to learn from drag queens, specifically Latinx queens, as they leverage everyday queerness and brownness in ways that contribute to pedagogy locally and globally, individually and collectively. Drawing on previous work examining the digital queer gestures of drag queen educators (Lizárraga & Cortez, 2019), this essay explores how non-dominant people that exist and fluctuate in the in-between of boundaries of gender, race, sexuality, the physical, and the virtual provide pedagogical overtures for imagining and organizing for new possible futures that are equitable and just. Further animated by Donna Haraway’s (2006) influential feminist post-humanist work, we interrogate how Latinx drag queens as cyborgs use digital technologies to enhance their craft and engage in powerful pedagogical moves. This essay draws from robust analyses of the digital presence of and interviews with two Latinx drag queens in the San Francisco Bay Area, as well as the online presence of a Xicanx doggie drag queen named RuPawl. Our participants actively drew on their liminality to provoke and mobilize communities around socio-political issues. In this regard, we see them engaging in transformative public cyborg jotería pedagogies that are made visible and historicized in the digital and physical world.
