The influence of multiple stressors on the spatial distribution of corals

open access: yesPeople and Nature, EarlyView.
Abstract Coral reef ecosystems are widely threatened by global change, yet the cumulative impacts of multiple interacting stressors remain difficult to quantify over space and time. We evaluate how long‐term artisanal fishing effort, blast fishing, human population density and marine protected areas (MPAs) interact with biophysical and seascape ...

Community‐based marine restoration to generate social licence and ecological knowledge for upscaling oyster reef restoration

open access: yesPeople and Nature, EarlyView.
Abstract Community‐led restoration operates at the intersection of ecological feasibility and social acceptability. In the marine realm, restoration is challenging due to gaps in ecological knowledge on how and where to restore lost ecosystems and limited public engagement that provides social licence for restoration.

Measuring Complexity in an Aquatic Ecosystem

open access: yes, 2013
We apply formal measures of emergence, self-organization, homeostasis, autopoiesis and complexity to an aquatic ecosystem; in particular to the physiochemical component of an Arctic lake. These measures are based on information theory.

Testing the impact of diagenesis on the delta O-18 and delta C-13 of benthic foraminiferal calcite from a sediment burial depth transect in the equatorial Pacific [PDF]

open access: yes, 2013
Stable oxygen and carbon isotope (δ18O and δ13C) values measured in foraminiferal calcite are one of the primary tools used in paleoceanography. Diagenetic recrystallisation of foraminiferal calcite can act to reset primary isotopic values but its ...

Impacts of a Century‐Old Urban Dam on Water Quality and Habitat Composition, Flint River, Flint, MI

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Dams significantly influence river ecosystems worldwide, fragmenting habitats, altering sediment transport, and reducing biodiversity. Urban rivers are especially vulnerable, where dams compound stressors such as channelization, pollution, and degraded riparian zones. In response, dam removals are a growing restoration tool globally.

Effects of beach remourishment on the benthic macrofauna and the fishes of the nearshore zone at Sebastian Inlet State Recreation Area [PDF]

open access: yes, 1987
Approximately 100,000 cubic yards of sand was transported to the ocean beach to renourish the eroded beach front during the period December 1985 through May 1986.

In situ benthic fluxes from an intermittently active mud volcano at the Costa Rica convergent margin [PDF]

open access: yes, 2005
Along the erosive convergent margin off Costa Rica a large number of mound-shaped structures exist built by mud diapirism or mud volcanism. One of these, Mound 12, an intermittently active mud volcano, currently emits large amounts of aqueous dissolved ...

Making Waves: The Effects of Whitewater Parks on Fish Passage in Colorado

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Instream structures have fragmented riverine habitats throughout much of the world, including the Western USA. Whitewater parks (WWPs) are relatively new instream structures designed to create hydraulic waves for recreational boating and surfing by constricting flows into a steep chute or drop.
