Co-existence of Methanogenesis and Sulfate Reduction with Common Substrates in Sulfate-Rich Estuarine Sediments

open access: yesFrontiers in Microbiology, 2017
The competition between sulfate reducing bacteria and methanogens over common substrates has been proposed as a critical control for methane production.

Corrosion Performance of Prepainted Galvanized Steel After 8‐Year Outdoor Exposure Upon the Distance to the Seashore in Temperate Environment

open access: yesMaterials and Corrosion, EarlyView.
The corrosion performance of line‐produced prepainted galvanized steel products was investigated upon the distance to the seashore in temperate environment over 8‐year exposure. The rate of underpaint corrosion from cut‐edge was estimated and depended on the agressiveness of the site and the angle of exposure.

Short-term changes in the plankton of a highly homogeneous Basin of the Straits of Magellan (Paso Ancho) during spring 1994

open access: yesScientia Marina, 1999
Changes in nutrients, chlorophyll and zooplankton were followed for 11 d in a basin of the Straits of Magellan (Paso Ancho), characterized by a homogeneous water column during a spring event defined by a drastic change in wind stress and direction ...

Ecosystem size reverses the effect of the spatial coupling between autotrophic and heterotrophic ecosystems

open access: yesOikos, EarlyView.
The flow of non‐living resources between autotrophic and heterotrophic ecosystems can impact their ecosystem function. However, ecosystem size is similarly known to influence ecological properties and it is uncertain how the size of coupled ecosystems mediates the effect of resource flows.

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

open access: yesOikos, EarlyView.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

open access: yesOikos, EarlyView.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina
