Calcareous nannoplankton response to the latest Cenomanian Oceanic Anoxic Event 2 perturbation

Morphometric analyses were performed on Biscutum constans, Zeugrhabdotus erectus, Discorhabdus rotatorius and Watznaueria barnesiae specimens from five sections spanning the Cenomanian-Turonian boundary interval including Oceanic Anoxic Event (OAE) 2 (~ 94 Ma). Show More Summary

Elevated temperature has adverse effects on GABA-mediated avoidance behaviour to sediment acidification in a wide-ranging marine bivalve

Sediment acidification is known to influence the burrowing behaviour of juvenile marine bivalves. Unlike the alteration of behaviour by ocean acidification (OA) observed in many marine organisms, this burrowing response to present-day...Show More Summary

Achieving accurate spectrophotometric pH measurements using unpurified meta-cresol purple

For best accuracy, spectrophotometric characterizations of seawater pH are obtained using a purified pH-sensitive dye—usually meta-cresol purple (mCP) for typical ranges of seawater pH. In recognition of practical limitations, though, a straightforward method is here proposed to improve measurements made using unpurified mCP. Show More Summary

Lower Nehalem Watershed Council Speaker Series: Ocean Acidification, 11 May 2017

Date & Location: 11 May 2017, Pine Grove Community House (225 Laneda Ave, Manzanita) Ocean acidification is a global challenge to the sustainability of marine ecosystems. It is a major water quality issue linked to the reduction of shell material in our coastal waters and the mortality of shell forming marine life worldwide. Oregon has emerged […]

Large-scale seaweed cultivation diverges water and sediment microbial communities in the coast of Nan’ao Island, South China Sea

Seaweed cultivation not only provides economy benefits, but also remediates the environment contaminated by mariculture of animals (e.g., fish, shrimps). However, the response of microbial communities to seaweed cultivation is poorly understood. Show More Summary

Effects of elevated CO? on speckled sanddab (Citharichthys stigmaeus) behaviour

The direct and indirect effects of ocean acidification (OA) are a growing concern, particularly in areas already experiencing elevated levels of oceanic CO?. Studies with marine fishes suggest that elevated CO? levels may affect behavior by interfering with an important brain neurotransmitter. Show More Summary

What goes into rescuing, rehabilitating and releasing wild African penguins? Last year, aviculturist Monika Rohrer traveled to SANCCOB saves seabirds in South Africa to help care for 150 rescued penguin chicks!  For your #WorldPenguinDay viewing pleasure, here’s her story! 

Ocean Signs at the #MarchForScience

One of the beauties of the various marches for science around the world was scientists and science lovers really letting their inner science-punner out. Signs ran from the serious to the silly, but all carried a message of love for the oceans. I’m trying to collect as many as I can – so, please, post […]

Inorganic carbon physiology underpins macroalgal responses to elevated CO2

Beneficial effects of CO2 on photosynthetic organisms will be a key driver of ecosystem change under ocean acidification. Predicting the responses of macroalgal species to ocean acidification is complex, but we demonstrate that the response of assemblages to elevated CO2 are correlated with inorganic carbon physiology.

Sea creature dissolves fast in warm, acidic ocean

Marine animals that live in warm as well as acidic oceans are dissolving quickly under conditions at the Northern California coast, says a study from the University of California, Davis. This applies especially to the bryozoans. Scientists published their study in the journal Proceedings of the Royal Society B: Biological Sciences. Researchers from the UC […]

Effect of pH on temperature controlled degradation of reactive oxygen species, heat shock protein expression, and mucosal immunity in the sea cucumber Isostichopus badionotus

This study evaluated the effect of pH on the activity of antioxidant and immune enzymes in the sea cucumber Isostichopus badionotus exposed to different temperatures. The organisms (530 ±110 g) were exposed to 16, 20, 24, 28, 30, 34 and 36°C for 6 h to evaluate thermal limits at two water pH values (treatment = […]

Effects of elevated nutrients and CO2 emission scenarios on three coral reef macroalgae

Coral reef macroalgae are expected to thrive in the future under conditions that are deleterious to the health of reef-building corals. Here we examined how macroalgae would be affected by exposure to future CO2 emission scenarios (pCO2 and temperature), enriched nutrients and combinations of both. Show More Summary

The effects of elevated temperature and dissolved ?CO2 on a marine foundation species

Understanding how climate change and other environmental stressors will affect species is a fundamental concern of modern ecology. Indeed, numerous studies have documented how climate stressors affect species distributions and population persistence. Show More Summary

Impacts of CO2-induced ocean acidification on predator detection ability and developementof temperate fish

Ocean acidification, caused by elevated levels of atmospheric carbon dioxide (CO2), is recognized as a serious threat to marine ecosystems. Until now, most studies have focused on marine calcifying organisms, due to dependence on calcium carbonate, which is likely to become limited under future acidification scenarios. Less attention has been given to fish, but recent […]
