    Gu Xiong : The River

    No full text
    Gu Xiong’s installation “The River” is described by O’Brian as a meditation on migrancy and displacement. The author situates the work within the life of the artist, who left China because of political oppression, and the history of the Canadian West, which has marginalized its Chinese inhabitants. Short poetic texts by Gu Xiong in which he identifies with spawning salmon are included. Biographical notes. 19 bibl. ref

Habitat. Streamlet, about 0.3–0.5 m in depth, with many small stones at the bottom. Remarks. Plap with serrated ventral extensions was also found in a small number of torrenticolid mites, such as T. dentifera Wiles, 1991 (Gu et al. 2020b), T. dentipalpis Jin, 1997 (Jin 1997), T. alargada Goldschmidt, 2007 (Goldschmidt 2007) and T. turkestanica (Sokolow, 1926) (Pešić & Smit 2009). However, the aforementioned torrenticolid mites only have a regular (rod-shaped or rectangular) ventral extension on P-2. T. multiserrater Gu & Guo sp. nov., can be distinguished from other members of the genus by P-2 with a jagged serrated extension on ventrum, which like a flower cluster or coral, and one ventral seta at the base of ventral extension; P-3 with an obvious serrated terminal-margin, one serrated ventral extension, and three dorsal setae and one ventral seta (Figs. 1C, 3C). Etymology. The specific name, multiserrater, is a combination from the Latin words: “ multi- ” and “ serrated ”, referring to this species having multiple serrated extensions, forming a jagged serrated extension on ventrum (Figs. 1C, 3C); used as a noun in apposition. Distribution.
