Fisheries can have a large impact on marine ecosystems, because the effects of removing predatory fish may cascade down food web. The implications these cascading processes system functioning and resilience remain source intense scientific debate. By using field data covering 30-year period, we show for Baltic Sea that underlying mechanisms trophic cascades produced shift in ecosystem after collapse top predator cod. We identified an ecological threshold, corresponding to planktivore...

The sizes of individual organisms, rather than their taxonomy, are used to inform management and conservation in some aquatic ecosystems. European Science Foundation Research Network, SIZEMIC, facilitates integration such approaches with the more taxonomic terrestrial ecology. During its 4-year tenure, Network is bringing together researchers from disciplines including theorists, empiricists, government employees, practitioners, via a series meetings, working groups research visits....
Cultural ecosystem services (CES) reflect peoples’ physical and cognitive interactions with nature are increasingly recognised for providing non-material benefits to human societies. Whereas coasts, seas, oceans sustain a great proportion of the population, CES provided by these ecosystems have remained largely unexplored. Therefore, our aims were (1) analyse state research on marine coastal CES, (2) identify knowledge gaps, (3) pinpoint priorities way forward. To accomplish objectives, we...
Abstract Modern approaches to Ecosystem-Based Management and sustainable use of marine resources must account for the myriad pressures (interspecies, human environmental) affecting ecosystems. The network feeding interactions between co-existing species populations (food webs) are an important aspect all ecosystems biodiversity. Here we describe discuss a process evaluate selection operational food-web indicators in evaluating ecosystem status. This brought together experts ecology, resource...
A primary goal of macroecology is to identify principles that apply across varied ecosystems and taxonomic groups. Here we show the allometric relationship observed between maximum abundance body size for terrestrial plants can be extended predict population densities marine phytoplankton. These results imply producers similarly constrained in systems by rates energy supply as dictated a common scaling law. They also highlight existence general mechanisms linking individual metabolism...
Abstract Improving the health of coastal and open sea marine ecosystems represents a substantial challenge for sustainable resource management, since it requires balancing human benefits impacts on ocean. This is often exacerbated by incomplete knowledge lack tools that measure ocean ecosystem in way allows consistent monitoring progress towards predefined management targets. The such limits capabilities to enact enforce effective governance. We introduce Baltic Health Index (BHI) as...
The evaluation of the time–series data set primary production, chlorophyll a (1985–1996) and toxic phytoplankton species abundance measurements (1986–1996) in Gullmar Fjord as part Swedish Monitoring Program, revealed importance considering climatic environmental forces among factors that may be responsible for observed fluctuations. results suggested occurrence blooms Skagerrak related to changes phase North Atlantic Oscillation (NAO). Dinophysis were NAO, temperature salinity fluctuations...
Using long-term data on two kangaroo rats in the Chihuahuan Desert of North America, we fitted logistic models including exogenous effects seasonal rainfall patterns. Our aim was to test intraspecific interactions and explaining predicting numerical fluctuations these rats. We found that fit both sets quite well; Dipodomys merriami showed lower maximum per capita growth rates than ordii, cases were nonlinear. Summer appears be most important effect for rodent populations; this variable able...
Quantifying the impact of lower trophic level species abundance on higher predators (and vice versa) is critical for understanding marine ecosystem dynamics and implementing ecosystem-based management. Trophic models generally predict a tight coupling between prey fish predators, such that results in predators. This assumes predator feeding rates to some degree are limited by availability. Despite being key component predator-prey interactions multi-species fisheries management, relatively...
To investigate forcing factors on a coastal plankton food web, primary production was measured every 2 weeks for 28 years. On decadal scale, the North Atlantic Oscillation (NAO) correlated positively to (r = 0.44, P 0.021) and winter surface nitrate 0.60, 0.0014) phosphate 0.66, 0.0003; r 0.0014). This suggests that climate through increased wind vertical mixing leads higher entrainment of nutrients which stimulate yearly production. The highest occurred in summer (1105 ± 16 mg C m−2 day−1)...
In 1976 the North Pacific climate shifted, resulting in an average increase of water temperature. Gulf Alaska shift was followed (i.e. early 1980s) by a gradual but dramatic abundance groundfish species that typically prey on pre-recruitment stages walleye pollock. present study we used previously parameterized model to investigate effect these and biological changes recruitment dynamics pollock Alaska. Simulations covered 1970–2000 time frame emphasized medium-to-long temporal scale about...
A growing concern is arising to recognize that ecosystem services (ES) production often requires the integration of non-natural capital with natural in a process known as co-production. Several studies explore co-production different terrestrial ecosystems, such agriculture or water delivery, but less attention has been paid marine ecosystems. Coastal activities aquaculture, shellfish harvesting, and small-scale fishing deliver important benefits for seafood provision, are also inextricably...
The oceans are by far the largest carbon sink and estimated to have absorbed roughly 40 percent of anthropogenic dioxide emissions since beginning industrial era. climate services performed can be described as an interaction between a physical biological pump. Whereas role pump is well established, full scale provided has only recently been understood. This made up different marine species, from microbes mammals. Many these species managed under international law sea subject concept Maximum...

Mean trophic level (MTL) of landings and primary production required (PPR) by fisheries are increasingly used in the assessment sustainability fisheries. However, their present form, MTL PPR prone to misinterpretation. We show that it is important account for actual catch data, define an appropriate historical spatial domain, carefully consider effects management, based on results from a case study Swedish during past century.
