Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

open access: yesOikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Impact of operational parameters on turbidity generation in cutter suction dredging: Insights from a numerical model and sensitivity analysis

open access: yesApplied Ocean Research
The cutter suction dredger (CSD) is one of the main vessels utilized in the dredging industry. The dynamic actions related to its rotating cutter head are the main trigger for sediment release and turbidity generation by this vessel.

Contrasting effects of temperature across trophic levels in geothermally warmed soil food webs

open access: yesOikos, EarlyView.
Global warming is altering the structure and dynamics of ecological communities, with significant consequences for soil food webs. Rising temperatures are expected to accelerate metabolic rates in organisms, potentially altering species interactions, and the structure and energetics of food webs.

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

open access: yesPeople and Nature, EarlyView.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Structural and functional biological assessment of aggregate dredging intensity on the Belgian part of the North Sea [PDF]

open access: yes, 2014
Marine aggregate dredging in the Belgian part of the North Sea (BPNS) is restricted to four dedicated concession zones. Within these zones, there are areas under different dredging pressure, but with the advantage that these are situated within a similar
