Tippy Rock Bay low intertidal with <i>Boltenia villosa</i> (Stimpson, 1864) and <i>Metandrocarpa taylori</i>.</p> <p>This species is usually found as an epibiont growing over solitary ascidians or various algal species. The small zooids up to 3 mm in height are connected by stolons; colonies may be quite large and composed of hundreds of zooids. Rarely some of the zooids in a colony may be completely embedded in a common transparent tunic, though in each zooid the siphons open independently at the tunic surface. Zooids are yellowish-green with four rows of stigmata. Reproduction is both sexual with the embryos incubated in a special pouch in the atrial area, or asexual by stolonic budding. A detailed morphological description is given by Ritter (1893), Huntsman (1912b), and Van Name (1945). This is a common native species from southern Alaska to southern California on both natural and artificial surfaces (Huntsman 1912b; Van Name 1945; Abbott & Newberry 1980; O’Clair & O’Clair 1998; Lamb & Hanby 2005).</p>Published as part of <i>Lambert, Gretchen, 2019, The Ascidiacea collected during the 2017 British Columbia Hakai MarineGEO BioBlitz, pp. 401-436 in Zootaxa 4657 (3)</i> on page 421, DOI: 10.11646/zootaxa.4657.3.1, <a href="http://zenodo.org/record/3371886">http://zenodo.org/record/3371886</a>
Styela truncata Ritter 1901
No full textStyela truncata Ritter, 1901 Figure 11F IHAK 31 BHAK 1695, 1696 UF 2519, 2520. Triquet Island Macro site, Scuba, 8 m. Very small; on Pugettia richii. With D. listerianum. IHAK 37 BHAK 1706 UF 2523. Crazy Town surge channel, Scuba, 5 m. Covered with P. annectens; small but with many brooded uncleaved embryos; on kelp holdfast, wave–exposed. IHAK 44 BHAK 1716 UF 2529. Rattenbury Pinnacle, Scuba, 21 m. No larvae. ZHAK 35 BHAK 3254 UF 2572. Sasquatch Commode tidepool. Small, 7 mm long, but with large brood of embryos. This small species may be difficult to distinguish from S. gibbsii without dissection, though the body is almost always somewhat twisted as in Fig. 11F and never attains a length of over 3–4 cm. Often (though not always) the anterior end is more slender, with the posterior half more bulbous. There are several anatomical differences from S. gibbsii. There is always only one longitudinal vessel between each of the four pharyngeal folds (vs. four to six for S. gibbsii). There are two elongate gonads per side as in S. gibbsii, but in S. truncata the anterior tips of the ovaries curve posteriorly (Abbott & Newberry 1980), resulting in internal oocyte release and fertilization. It is a brooder and brooded embryos can almost always be found in the atrial cavity during the summer breeding season. A detailed morphological description is given by Ritter (1901), Van Name (1945) and Lambert & Sanamyan (2001).

Ep. #095 - Gretchen Bakke
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Ofcymene and Ofdominic share their thoughts on The Handmaid’s Tale and then (17:20) we are delighted to welcome to the podcast, Gretchen Bakke, anthropologist and author of the celebrated The Grid: The Fraying Wires between Americans and our Energy Future (Bloomsbury, 2016). We begin with this week’s announcement of the termination of the Clean Power Plan and the politics of “baseload energy” today. From there, we cover why electricity is a commodity like no other, how electricity is actually like polyamorous love, the challenges of writing for a wider public, and the infrastructural revolution that we are experiencing (but not always aware of). Gretchen explains how the future of electrical infrastructure has come into focus only very recently and discusses how subtraction (from the grid) may become a key resource in the future. We talk about the unreliable state of the U.S. grid and how it prompted the military to pioneer the use of microgrids. We ask whether we can trust utilities to work with us on creating a more distributed and decarbonized electrical infrastructure. And Gretchen suggests that the utility model may already be dead. We wrap up with the place of conservation in the transition, how hyperlocal production could reduce our electricity consumption 40% with no immediate change in lifestyle, and why government (and not markets or philanthropy) needs to drive the transition

The "Texas Women : A Celebration of History" exhibit : second-wave feminism, historical memory, and the birth of a "Texas women's history industry"
No full texttextTouring the state in the early 1980s, the “Texas Women: A Celebration of History” exhibit was the first attempt to create a comprehensive, public Texas women’s history narrative. Surprisingly, the exhibit was organized not by academics or museum professionals, but rather by the Texas Foundation for Women’s Resources—a nascent second-wave feminist non-profit organization composed of up-and-coming political activists such as Ann Richards, Sarah Weddington, Jane Hickie, and Martha Smiley. Through an analysis of the exhibit, as well as archival research and oral histories with many of the participants, this thesis explores the reasons that a feminist organization with finite resources would choose to focus on the production of women’s history as a tool of feminist activism. The “Texas Women” exhibit was a uniquely effective way for the members of the Texas Foundation for Women’s Resources to express their feminist values in a culturally palatable way and to create embodied moments of feminist consciousness for their audience. Furthermore, it paved the way for the organization’s future successful feminist projects, fed the production of Texas women’s history initiatives around the state, and served as a springboard that helped launch Ann Richards’ successful political career.Women's and Gender Studie

Euherdmania claviformis
No full textEuherdmania claviformis (Ritter, 1903) Figure 9 E–F IHAK 60 BHAK 3243, 1738 UF 2549. Rattenbury Pinnacle, Scuba, 17–20 m. RHAK 6 BHAK 0995. Low rocky intertidal. Tubes 6 cm long. Clumps of long thin colorless zooids usually almost completely encrusted and embedded with grey sand, each zooid separate except at the common base formed from tightly interwoven branching basal stolons. Sometimes the anterior individual tubes are clear of sand (Fig. 9F). The thorax is comprised of 12 rows of very short stigmata. The esophageal region is very extended, with the ridged stomach (about six or seven plications) near the posterior end, followed by the testes and the heart. Ritter (1903) described this species in great detail, so impressed by its difference from all other known colonial ascidians that he established a new family and genus for it. While Ritter himself had to change the family and genus names due to their being preoccupied (Ritter 1904), this single genus family is still recognized as unusual, and contains only a few species. A detailed morphological description is also given by Van Name (1945); Trason (1957) described the larva and early post–settlement development. The present study extends the distribution from California (Abbott & Newberry 1980; Abbott et al. 2007) northward to Washington (unpublished observations) and British Columbia (present study).Published as part of Lambert, Gretchen, 2019, The Ascidiacea collected during the 2017 British Columbia Hakai MarineGEO BioBlitz, pp. 401-436 in Zootaxa 4657 (3) on page 416, DOI: 10.11646/zootaxa.4657.3.1, http://zenodo.org/record/337188
