Some Observations of Morphology and Behavior of a Hyperbenthic Misophrioid Copepod
Full text linkThe locomotion, feeding, excretion, and oviposition of a member of the copepod family Misophriidae were observed based on a live specimen collected from a sandy bottom at a depth of 52 m off Nagannu Island, Okinawa, Japan. This species is related to Arcticomisophria Martínez Arbizu and Seifried, 1996 in the armature of leg 1, but the fifth leg is much more reduced. The combination of morphological characters strongly suggests that it represents an undescribed genus. The maxillipeds played a major role in attaching to the bottom and in crawling, while the antennae and mandibular palps were involved in slow swimming along the bottom. It fed on small-sized cultured phytoplankters, and excreted numerous fecal pellets. The female carried 4-5 eggs of 0.09 mm diameter that were loosely attached to the urosome. Nearly complete nuclear 18S and 28S rRNA gene sequences and a partial mitochondrial cytochrome c oxidase subunit 1 (CO1) gene sequence were obtained and are made available for future phylogenetic and systematic work
Cognitive Dissonance in the Self-Identifying Processes of Multiracial People
Full text linkThis essay discusses the effects of internalized racism on multiracial people, specifically those who claim a mix of white and non-white. The paper first establishes the opposing representations of whiteness and racialized groups as well as the historic and modern disenfranchisement of racialized people in Canada. I argue that cognitive dissonance, the unpleasant mental state that occurs in people when conflicting thoughts and feelings are present, is triggered by belonging to different racial groups when structural hegemony and socialized whiteness require race to remain immutable. The cognitive dissonance propagates internalized racism as the mixed-race person attempts to rid themselves of these conflicting feelings. The paper draws on Edward Said’s Orientalism and Franz Fanon’s concept of the inferiority complex. While also acknowledging that nonmixed racialized groups are impacted by internalized racism due to the disenfranchisement and marginalization of their groups as a whole, Said and Fanon’s theories are applied to half-white mixed-race people in this essay to further analyze the form that internalized racism takes and how it impacts the way in which they identify
Featured Artist
Full text linkIranian born-Oakland based artist, Sara Emsaki, works primarily in painting, re-appropriating images that target gender roles and their subsequent power dynamics. Her work is aesthetically influenced by Islamic geometry and Persian miniature painting. She is a recipient of the 2015 Wendy Sussman award in painting and the Eisner Prize for the highest achievement in the creative arts. Emsaki gained a BFA in 2016 from the University of California, Berkeley, with an honors distinction
The Evolution of the Thermal Niche Across Locally Adapted Populations of the Copepod Tigriopus californicus
Full text linkLocal adaptation to different thermal environments is often expected to result in trade-offs in other measures of performance, thermal or otherwise. Populations of the copepod Tigriopus californicus found along the Pacific coast of North America have previously been shown to display patterns consistent with local adaptation and thermal trade-offs. Much of the work on this species has focused on performance at high and moderate temperatures with the lower thermal performance explored to a lesser degree. In this study, measures of both high and low thermal performance are examined for a set of eight T. californicus populations spanning a range from Central Baja California, Mexico to the State of Washington, USA. High temperature survival decreases with increasing latitude while chill coma recovery improves with increasing latitude. Comparisons of these measures among populations along with previous results suggest that there is a shift in the thermal niche in this species rather than other forms of trade-offs such as specialist/generalist trade-offs
