Using a social‐ecological macrosystems framework to understand how human activities alter ecological synchrony

People and Nature, EarlyView.
Abstract Different aspects of ecological systems, biotic or abiotic, often fluctuate in coordinated patterns over space and time. Such high concordance between ecological processes is often referred to as ecological synchrony. Human activities, including and beyond climate change, have the potential to alter ecological synchrony by disrupting or ...

The paradox of mosquito net fishing: Complex socio‐ecological trade‐offs in southwestern Madagascar

People and Nature, EarlyView.
Abstract Small‐scale fisheries are vital for the livelihoods, nutrition and well‐being of millions of people in coastal regions. In many parts of the Global South, rising poverty, limited alternatives and declining resources have driven the spread of mosquito net fishing (MNF), a non‐selective practice using repurposed health‐distributed nets.

Ecosystem Functioning Under the Influence of Bottom-Trawling Disturbance: An Experimental Approach and Field Observations From a Continental Slope Area in the West Iberian Margin

Frontiers in Marine Science, 2020
Understanding the effects of bottom-trawling induced changes in benthic community structure, diversity and ecosystem functioning across different benthic-size components is imperative to determine the future sustainability of bottom-trawling fisheries in

A review of the FATIMA Yellow Sea field campaign research

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The FATIMA marine fog project took place over the Sable Island region of eastern Canada (summer 2022) and the Yellow Sea of the Republic of Korea (ROK, summer 2023). Its goals are to improve marine fog monitoring and forecasting. Instrumented multiple research vessels, aircraft, tethered balloon and autonomous systems, ocean observation sites, and ...

Assessing the overlap between fishing and chondrichthyans exposes high‐risk areas for bycatch of threatened species

Ecosphere
Chondrichthyans (sharks, rays, skates, and chimaeras) make up one of the oldest and most ecologically diverse vertebrate groups, yet they face severe threats from fishing, necessitating improved management strategies. To effectively manage these species,

Atmospheric CO2 emissions and ocean acidification from bottom-trawling

Frontiers in Marine Science
Trawling the seafloor can disturb carbon that took millennia to accumulate, but the fate of that carbon and its impact on climate and ecosystems remains unknown.

Trawling in the Mediterranean: An Exploration of Empirical Relations Connecting Fishing Gears, Otterboards and Propulsive Characteristics of Fishing Vessels

Frontiers in Marine Science, 2019
Fishing pressure is often expressed in terms of a vessels physical attributes, like tonnage and engine power, while a common definition of fishing capacity identifies vessel size as a convenient proxy for the size of the gear used.
