Certification is a market-based incentive
• Recognise that certification is not suitable for all fisheries

We use autonomous gas measurements to examine the metabolic balance (photosynthesis
minus respiration) of coastal Antarctic waters during the spring/summer growth season. Our observations
capture the development of a massive phytoplankton bloom and reveal striking variability in pCO₂ and
biological oxygen saturation (ΔO₂/Ar) resulting from large shifts in community metabolism...

In the context of the restriction of production, French agriculture modifies its activities by developing multifunctionality. This concept translates the fact that, beyond the saleable production of agricultural and food processing products, the agricultural activity fulfills other functions: economic, social, environmental. Multifunctionality of agriculture is implemented in a number of...

The inaccessibility of open ocean habitat and the cryptic nature of small
animals are fundamental problems when assessing the distribution of
oceanic-stage sea turtles and other marine animals sharing similar life-history
traits. Most methods that estimate patterns of abundance cannot be
applied in situations that are extremely data limited. Here,...

Multiple analytical techniques were used to evaluate the impact of multiple parasite species on
the mortality of threatened juvenile coho salmon (Oncorhynchus kisutch) from the West Fork Smith
River, Oregon, USA. We also proposed a novel parsimonious mathematical representation of
macroparasite distribution, congestion rate, which i) is easier to use...
