Common octopus settled in human-altered Mediterranean coastal waters: from individual home range to population dynamics

A spatially explicit capture-recapture (SCR) model was applied to estimate simultaneously population parameters and individual activity (i.e. home range size) of O. vulgaris, based on experimental mark-recapture data in a human-altered Mediterranean coastal area. Seventy-two octopuses were captured, tagged with subcutaneous PIT-tags and released. Nineteen tagged individuals were...

Parent-offspring conflict over reproductive timing: ecological dynamics far away and at other times may explain spawning variability in Pacific herring

Timing of reproduction may be of crucial importance for fitness, particularly in environments that vary seasonally in food availability or predation risk. However, for animals with spatially separated feeding and breeding habitats, optimal reproductive timing may differ between parents and their offspring, leading to parent-offspring conflict. We assume that offspring have...

New insights into behavioural ecology of European seabass off the West Coast of France: implications at local and population scales

From 2010 to 2012, 246 data storage tags were deployed on European seabass in the Iroise Natural Marine Park, a marine protected area (MPA) off west Brittany, France. A return rate of 14.6% associated with long time series of data provided new information on fish ecology (e.g. maximum experienced depth greater than 225 m, temperature range 6.80–21.87°C). Depth and temperature...

Preparing for the future: integrating spatial ecology into ecosystem-based management

Marine resource management is shifting from optimizing single species yield to redefining sustainable fisheries within the context of managing ocean use and ecosystem health. In this introductory article to the theme set, “Plugging spatial ecology into ecosystem-based management (EBM)” we conduct an informal horizon scan with leaders in EBM research to identify three rapidly...

Obstinate nature

Resolving ecological patterns is challenging but fascinating as it generates new ways of looking at nature. I recapitulate here four independent scientific ideas that I developed throughout my career and that have contributed to a better understanding of the functioning of marine ecosystems. The optimal environmental window relating wind intensity and fish recruitment, the...

Taking stock of fisheries science through oral history: voices from NOAA’s Fishery Science Centers

The application of historical perspectives and the documentation of long-term change in and views about the ocean is increasingly sought to frame and contextualize current issues facing marine science and policy. One of the important methods for informing such an historical perspective is through the use of oral histories, long used by social scientists for insight into local...

Climate sensitivities and uncertainties in food-web pathways supporting larval bluefin tuna in subtropical oligotrophic oceans

Compared with high-latitude seas, the ecological implications of climate change for top consumers in subtropical regions are poorly understood. One critical area of knowledge deficiency is the nature of food-web connections to larvae during their vulnerable time in the plankton. Bluefin tuna (BFT) are highly migratory temperate species whose early life stages are spent in ultra...

Adapting the dynamic energy budget (DEB) approach to include non-continuous growth (moulting) and provide better predictions of biological performance in crustaceans

Dynamic energy budget (DEB) theory offers a comprehensive framework for understanding the overall physiological performance (growth, development, respiration, reproduction, etc.) of an organism over the course of its life cycle. We present here a simplified DEB model for the swimming crab Liocarcinus depurator. To the best of our knowledge, this is the first to be presented for...

Adaptation strategies of coastal fishing communities as species shift poleward

In this period of environmental change, understanding how resource users respond to such changes is critical for effective resource management and adaptation planning. Extensive work has focused on natural resource responses to environmental changes, but less has examined the response of resource users to such changes. We used an interdisciplinary approach to analyse changes in...

Chronobiology and the design of marine biology experiments

Marine habitats are shaped by several geophysical cycles ranging from a few hours (tidal and solar cycles) to a year (seasons). These cycles have favoured the selection of endogenous biological clocks. Such a clock is a molecular time-keeping mechanism that consists of a set of core clock genes whose expression oscillates. The clocks produce biological rhythms and influence...

Comparison of marine and terrestrial ecosystems: suggestions of an evolutionary perspective influenced by environmental variation

The transition of plants and animals from sea to land required adaptation to a very different physical and chemical environment. In this paper, we focus on the consequences of the differences between the magnitude of the variability of ocean and atmospheric dynamics, with the ocean environment (in particular temperature and currents) being two to three orders of magnitude less...

Measuring fisheries performance using the “Goldilocks plot”

Most reporting of stock status accumulated at a national or regional level gives statistics on what proportion of the stocks are below some abundance threshold or above some fishing mortality rate threshold. This approach does not convey useful information on the performance of the fisheries management system in maximizing long-term sustainable yield, which is the primary...

Clarifying mandates for marine ecosystem-based management

Mandates to execute ecosystem-based management exist but are not implemented sufficiently enough to reap the benefits of a growing blue economy.

Continuous learning, teamwork, and lessons for young scientists

This paper describes my research on fish population dynamics, which has aimed to improve the information available for management and conservation. Through numerous collaborations, my research program addressed three main objectives. (1) Increase the understanding of spatial and temporal variation in productivity of fish populations. (2) Quantify uncertainties and risks in...

Breaking the myths (or how to have a successful career in science)

The article is a recollection of the ups and downs of my career as a research scientist. It does not chronicle my career in the standard way; there is no timeline of events and only a few details of the type of research that I have devoted my life to. I feel the take-home messages are relevant no matter what type of science you do. The narrative jumps around between periods of my...

A review of the influence of marine habitat classification schemes on mapping studies: inherent assumptions, influence on end products, and suggestions for future developments

The production of marine habitat maps typically relies on the use of habitat classification schemes (HCSs). The choice of which HCS to use for a mapping study is often related to familiarity, established practice, and national desires. Despite a superficial similarity, HCSs differ greatly across six key properties, namely, purpose, environmental and ecological scope, spatial...

Inclusion of ecosystem information in US fish stock assessments suggests progress toward ecosystem-based fisheries management

The appetite for ecosystem-based fisheries management (EBFM) approaches has grown, but the perception persists that implementation is slow. Here, we synthesize progress toward implementing EBFM in the United States through one potential avenue: expanding fish stock assessments to include ecosystem considerations and interactions between species, fleets, and sectors. We reviewed...

Sustainable use of Baltic Sea resources

The BONUS symposium “Science delivery for sustainable use of the Baltic Sea living resources” held in Tallinn, Estonia, in October 2017 was an opportunity for the presentation and discussion of 107 papers that examined the state and dynamics of living resources of the Baltic Sea, and associated management challenges. The symposium included a half-day stakeholder panel discussion...

Shifting boundaries of water, ice, flora, fauna, people, and institutions in the Arctic and Subarctic

An international Open Science Meeting entitled Moving in, out, and across the Subarctic and Arctic marine ecosystems: shifting boundaries of water, ice, flora, fauna, people, and institutions, took place 11–15 June 2017 in Tromsø, Norway. Organized by the Ecosystem Studies of Subarctic and Arctic Seas programme and cosponsored by the International Council for the Exploration of...

Identification of the farm of origin of Atlantic salmon smolt escapees in a freshwater Scottish loch using single-nucleotide polymorphic markers

In this article, we present the first use of genetic assignment to determine the origins of farmed Atlantic salmon (Salmo salar L.) escaping directly into freshwater. Juvenile fish (n = 220) sampled from rotary screw traps operating on tributaries of Loch Shin in Scotland had characteristics suggesting they were of farm origin (scale losses, fin damage, and vaccination marks). To...

A new approach for estimating stock status from length frequency data

This study presents a new method (LBB) for the analysis of length frequency data from commercial catches. LBB works for species that grow throughout their lives, such as most commercially-important fish and invertebrates, and requires no input in addition to length frequency data. It estimates asymptotic length, length at first capture, relative natural mortality, and relative...

Harmful algal blooms and climate change: exploring future distribution changes

Harmful algae can cause death in fish, shellfish, marine mammals, and humans, via their toxins or from effects associated with their sheer quantity. There are many species, which cause a variety of problems around north-west Europe, and the frequency and distribution of algal blooms have altered in the recent past. Species distribution modelling was used to understand how harmful...
