Ocean acidification (OA) is predicted to have widespread implications for marine organisms, yet the capacity for species to acclimate or adapt over this century remains unknown. Recent transgenerational studies have shown that for some marine species, exposure of adults to OA can facilitate positive carryover effects to their larval and juvenile offspring(More)
Elevations in atmospheric carbon dioxide (CO2) are anticipated to acidify oceans because of fundamental changes in ocean chemistry created by CO2 absorption from the atmosphere. Over the next century, these elevated concentrations of atmospheric CO2 are expected to result in a reduction of the surface ocean waters from 8.1 to 7.7 units as well as a(More)
Predicting the impact of warming and acidifying on oceans on the early development life history stages of invertebrates although difficult, is essential in order to anticipate the severity and consequences of future climate change. This review summarises the current literature and meta-analyses on the early life-history stages of invertebrates including(More)
We present new optical and near-infrared imaging for a sample of 98 spectroscopically-selected galaxy groups at 0.25 < z < 0.55, most of which have velocity dispersions σ < 500 km/s. We use psf-matched aperture photometry to measure accurate colours for group members and the surrounding field population. The sample is statistically complete above a stellar(More)
We investigated how color preferences vary according to season and whether those changes could be explained by the ecological valence theory (EVT). To do so, we assessed the same participants' preferences for the same colors during fall, winter, spring, and summer in the northeastern United States, where there are large seasonal changes in environmental(More)
Ocean acidification is predicted to have severe consequences for calcifying marine organisms especially molluscs. Recent studies, however, have found that molluscs in marine environments with naturally elevated or fluctuating CO2 or with an active, high metabolic rate lifestyle may have a capacity to acclimate and be resilient to exposures of elevated(More)
The vacuum system of System C has been modified in order to obtain a lower base pressure and to reduce wall outgassing by the plasma. A 400-liter/sec VacIon pump was installed in place of the oil diffusion pump. All of the large O-ring seals were replaced by copper gaskets and Conflat flanges, and the remaining O-rings were replaced by Viton O-rings. A(More)
A. BEAM-PLASMA DISCHARGES 1. THE KITZELTRON From our beam-plasma discharge experiments we have discovered the following important characteristics: (i) Nearly 100 per cent ionization. When we fire a 10-kv, 10-amp electron beam into a hydrogen atmosphere 2 X 10-5 torr (-6 X 1011 mol/cc) a plasma density of approximately 1013/cc is created. This indicates that(More)
The plasma density of the electron-cyclotron resonance discharge (ECRD) has been measured with an 8-mm Fabry-Perot microwave interferometer. The ECRD experiment has been described in Quarterly Progress Report No. 73 (pages 81-85) and Quarterly Progress Report No. 75 (pages 120-121). The discharge is driven by a 2. 4-Gc, 1. 2-kw magnetron, powered by an(More)
