Rhetoric Of The Invisible (Or, How Bisexual People Demand To Be Seen), Olivia Wood

Publications and Research

While the term in its modern usage existed earlier, the word “bisexual” consolidated its meaning as a sexual identity during the 1970s. In the following decades, the term became the source of much consternation in the gay and lesbian communities, in part due to the pressures of political lesbianism and the stigmas of the AIDS epidemic. The first bisexual-specific organizations in the US and the UK formed in the early 1990s, yet bi people continue to struggle for visibility, representation, and acceptance, even within the LGBTQ+ community.

Drivers Of 20th Century Sea-Level Change In Southern New Zealand Determined From Proxy And Instrumental Records, Ed Garrett, W. Roland Gehrels, Bruce W. Hayward, Rewi Newnham, Maria J. Gehrels, Craig J. Morey, Sönke Dangendorf

CCPO Publications

In this paper we present new proxy-based sea-level reconstructions for southern New Zealand spanning the last millennium. These palaeo sea-level records usefully complement sparse Southern Hemisphere proxy and tide-gauge sea-level datasets and, in combination with instrumental observations, can test hypotheses about the drivers of 20th century global sea-level change, including land-based ice melt and regional sterodynamics. We develop sea-level transfer functions from regional datasets of salt-marsh foraminifera to establish a new proxy-based sea-level record at Mokomoko Inlet, at the southern tip of the South Island, and to improve the previously published sea-level reconstruction at Pounawea, located about 110 km to …

Assessment Of Temperature Optimum Signatures Of Corals At Both Latitudinal Extremes Of The Red Sea, Guilhem Banc-Prandi, Nicolas R. Evensen, Daniel J. Barshis, Gabriela Perna, Youssouf Moussa Omar, Maoz Fine

Biological Sciences Faculty Publications

Rising ocean temperatures are pushing reef-building corals beyond their temperature optima (T_opt), resulting in reduced physiological performances and increased risk of bleaching. Identifying refugia with thermally resistant corals and understanding their thermal adaptation strategy is therefore urgent to guide conservation actions. The Gulf of Aqaba (GoA, northern Red Sea) is considered a climate refuge, hosting corals that may originate from populations selected for thermal resistance in the warmer waters of the Gulf of Tadjoura (GoT, entrance to the Red Sea and 2000 km south of the GoA). To better understand the thermal adaptation strategy of GoA corals, …
