Abstract Global concern about human impact on biological diversity has triggered an intense research agenda drivers and consequences of biodiversity change in parallel with international policy seeking to conserve associated ecosystem functions. Quantifying the trends is far from trivial, however, as recently documented by meta‐analyses, which report little if any net local species richness through time. Here, we summarise several limitations a metric show that expectation directional under...
Abstract Nutrient pollution and reduced grazing each can stimulate algal blooms as shown by numerous experiments. But because experiments rarely incorporate natural variation in environmental factors biodiversity, conditions determining the relative strength of bottom–up top–down forcing remain unresolved. We factorially added nutrients at 15 sites across range marine foundation species eelgrass ( Zostera marina ) to quantify how control interact with gradients biodiversity forcing....
In the Baltic Sea, increased dominance of ephemeral and bloom-forming algae is presently attributed to nutrient loads. Simultaneously, coastal predatory fish are in strong decline. Using field data from nine areas covering a 700-km coastline, we examined whether formation macroalgal blooms could be linked composition community. We then tested predator or availability explain patterns two small-scale experiments, by comparing joint effects on algal net production enrichment with agricultural...
Abstract Ljunggren, L., Sandström, A., Bergström, U., Mattila, J., Lappalainen, Johansson, G., Sundblad, Casini, M., Kaljuste, O., and Eriksson, B. K. 2010. Recruitment failure of coastal predatory fish in the Baltic Sea coincident with an offshore ecosystem regime shift. – ICES Journal Marine Science, 67: 1587–1595. The dominant southwestern Sea, perch pike, have decreased markedly abundance during past decade. An investigation into their recruitment at 135 sites showed that both species...
Summary Seagrass and seaweed habitats constitute hotspots for diversity ecosystem services in coastal ecosystems. These are subject to anthropogenic pressures, of which eutrophication is one major stressor. Eutrophication favours fast‐growing ephemeral algae over perennial macroalgae seagrasses, causing habitat degradation. However, changes top‐down control, caused by, example, overfishing, may also have negative impacts on such by decreasing grazer control algae. Meanwhile, systematic...
Habitat-forming species sustain biodiversity and ecosystem functioning in harsh environments through the amelioration of physical stress. Nonetheless, their role shaping patterns distribution under future climate scenarios is generally overlooked. Focusing on coastal systems, we assess how habitat-forming can influence ability stress-sensitive to exhibit plastic responses, adapt novel environmental conditions, or track suitable climates. Here, argue that habitat-former populations could be...
Trophic cascades occur in many ecosystems, but the factors regulating them are still elusive. We suggest that an overlooked factor is trophic interactions (TIs) often scale-dependent and possibly interact across spatial scales. To explore role of scale for cascades, particularly occurrence cross-scale (CSIs), we collected analysed food-web data from 139 stations 32 bays Baltic Sea. found evidence a four-level cascade linking TIs two scales: at bay scale, piscivores (perch pike) controlled...
Climatic warming is a primary driver of change in ecosystems worldwide. Here, we synthesize responses species richness and evenness from 187 experimental studies quantitative meta‐analysis. We asked 1) whether effects on diversity were detectable consistent across terrestrial, freshwater marine ecosystems, 2) if correlated with intensity, duration, unit size temperature manipulations, 3) these interacted ecosystem types. Using multilevel mixed linear models model averaging, also tested the...
Abstract Regime shifts in ecosystem structure and processes are typically studied from a temporal perspective. Yet, theory predicts that large ecosystems with environmental gradients, should start locally gradually spread through space. Here we empirically document spatially propagating shift the trophic of aquatic ecosystem, dominance predatory fish (perch, pike) to small prey fish, three-spined stickleback. Fish surveys 486 shallow bays along 1200 km western Baltic Sea coast during...
Abstract Under rapid environmental change, opportunistic species may exhibit dramatic increases in response to the altered conditions, and can turn have large impacts on ecosystem. One such is three-spined stickleback (Gasterosteus aculeatus), which has shown substantial several aquatic systems recent decades. Here, we review population development of Baltic Sea, a brackish water ecosystem subject change. Current evidence points predatory release being central driver observed some areas,...
We examined long‐term changes in the macroalgal vegetation at Stora Bornö Island inner Gullmar Fjord on Swedish Skagerrak coast. This was made possible by access to a 1941 diving investigation. The same sites were reinvestigated 1998. Community composition and depth distributions of species compared analyzed with focus functional groups (size, thallus shape, life‐history traits). discovered significant decrease extension dramatic decline richness lower littoral (below 16 m depth) 57 years...
Shallow soft-sediment systems are mostly dominated by species that, strongly affecting sediment dynamics, modify their local environment. Such ecosystem engineering can have either sediment-stabilizing or sediment-destabilizing effects on tidal flats. They interplay with abiotic forcing conditions (wind, tide, nutrient inputs) in driving the community structure and generating spatial heterogeneity, determining composition of different communities associated species, thereby channelling...
Ecosystem engineers can strongly modify habitat structure and resource availability across space. In theory, this should alter the spatial distributions of trophically interacting species. article, we empirically investigated importance spatially extended modification by reef-building bivalves in explaining distribution four avian predators their benthic prey Wadden Sea—one world's largest intertidal soft-sediment ecosystems. We applied Structural Equation Modeling to identify important...
Increasing evidence shows that spatial interactions between sedentary organisms can structure communities and promote landscape complexity in many ecosystems. Here we tested the hypothesis reef-forming mussels (Mytilus edulis L.), a dominant intertidal ecosystem engineer Wadden Sea, abundances of burrowing bivalve Cerastoderma edule L. (cockle) neighboring habitats at relatively long distances coastward from mussel beds. Field surveys within around three beds showed peak cockle densities...
Abstract Latitudinal gradients in species interactions are widely cited as potential causes or consequences of global patterns biodiversity. However, mechanistic studies documenting changes across broad geographic ranges limited. We surveyed predation intensity on common prey (live amphipods and gastropods) communities eelgrass ( Zostera marina ) at 48 sites its Northern Hemisphere range, encompassing over 37° latitude four continental coastlines. Predation declined with all coasts but more...
Distribution of Earth’s biomes is structured by the match between climate and plant traits, which in turn shape associated communities ecosystem processes services. However, that climate–trait can be disrupted historical events, with lasting impacts. As environment changes faster than at any time human history, critical questions are whether how organismal traits ecosystems adjust to altered conditions. We quantified relative importance current environmental forcing versus evolutionary...
