Enhanced benthic biodiversity and primary productivity with reduced turbidity in a coastal receiving environment

open access: yesLimnology and Oceanography, EarlyView.
Abstract Sediment loading from land and turbidity in coastal waters has increased because of human activities in coastal catchments and through climate‐related increases in storm intensity and frequency. Here, we investigated changes in coastal seafloor biodiversity and ecosystem function across a suspended sediment concentration gradient in a New ...

Phosphoproteomes of Strongylocentrotus purpuratus shell and tooth matrix: identification of a major acidic sea urchin tooth phosphoprotein, phosphodontin

open access: yesProteome Science, 2010
Background Sea urchin is a major model organism for developmental biology and biomineralization research. However, identification of proteins involved in larval skeleton formation and mineralization processes in the embryo and adult, and the molecular ...

Ascidians increase in abundance on tropicalized reefs and may enhance benthic nitrous oxide production

open access: yesLimnology and Oceanography, EarlyView.
Abstract Nitrous oxide (N2O) is an ozone‐depleting greenhouse gas that has a global warming potential nearly 300 times greater than carbon dioxide. Although the oceans contribute about 21% of atmospheric global N2O emissions, we know relatively little about N2O dynamics in nearshore systems. Here, we document the fourfold increase in the abundance of a

Refuge trifecta: intertidal gastropods use pits to escape heat, wave action and predation

open access: yesOikos, EarlyView.
Refuges play a critical role in ecology and evolution. In hard intertidal shores, small pits attract benthic invertebrates such as gastropods, however, there exists little mechanistic understanding of the processes driving the active usage of these microhabitat features. We conducted a series of laboratory experiments to assess whether the marine snail
