Forests are of major importance to human society, contributing several crucial ecosystem services. Biodiversity is suggested positively influence multiple services but evidence from natural systems at scales relevant management scarce. Here, across a scale 400,000 km2, we report that tree species richness in production forests shows positive hump-shaped relationships with These include biomass, soil carbon storage, berry and game potential. For example, biomass was approximately 50% greater...
Summary 1. Despite recent interest in linkages between above‐ and below‐ground communities their consequences for ecosystem processes, much remains unknown about responses to long‐term change. We synthesize multiple lines of evidence from a ‘natural experiment’ illustrate how retrogression (the decline process rates due absence major disturbance) drives vegetation change, thus above‐ground carbon (C) sequestration, consumer biota. 2. Our study system involves 30 islands Swedish boreal forest...
Effects of species number and identity on the breakdown rate leaf litter were estimated in a laboratory experiment using leaf‐eating insects, three Plecoptera, as detritivores. We found significant differences between different this process single‐species experiment, but not when animal biomass was accounted for. When combined effect strongly reduced rendered insignificant, whereas had effect. This shows that rates ecosystem processes may benefit from richness even all belong to same guild,...
Boreal forest ecosystems are important drivers of the global carbon (C) cycle by acting as both sinks and sources atmospheric CO 2 . While several factors have been proposed determining ability boreal to function C sinks, little is known about their relative importance. In this study, we applied structural equation modelling a previously published dataset involving 30 boreal-forested islands that vary greatly in historic fire regime, order explore simultaneous influence believed be...
1. Leaf litter breakdown rates were assessed in 23 boreal streams of varying size (first–seventh order) central and northern Sweden. 2. Shredders most abundant small streams, while shredder species richness showed a hump‐shaped relationship with stream order, fourth order streams. 3. In partial least‐squares regression analysis, year, water temperature, abundance those factors correlating strongly leaf rates. Shredder was more correlated than abundance, biomass no such correlation. 4. These...
We removed stream-living macroinvertebrate shredder species in the sequences which they are predicted to disappear, response two common types of anthropogenic disturbances: acidification and organic pollution, analysed effects on leaf breakdown rates. The experiment was performed field microcosms using three species. Species identity significantly affected rates, while richness per se non-significant. simulated sequential loss showed large with observed rates being higher than expected from...
Summary We assessed the influence of agricultural land use on aquatic–terrestrial linkages along streams arising from changes in emergence aquatic insects. expected that terrestrial predators would respond to a change abundance and/or size structure emerging insects by an increase or decrease population size. measured flux emergent and invertebrate birds 10 across forest‐to‐agriculture land‐use gradient. also performed stable isotope analyses (hydrogen, carbon nitrogen) predators. Small...
Abstract Migration is an important life-history event in a wide range of taxa, yet many migrations are influenced by anthropogenic change. Although migration dynamics extensively studied, the potential effects environmental contaminants on migratory physiology poorly understood. In this study we show that anxiolytic drug water can promote downward behaviour Atlantic salmon ( Salmo salar ) both laboratory setting and natural river tributary. Exposing smolt to dilute concentration GABA A...
Production and human consumption of pharmaceuticals result in contamination surface waters worldwide. Little is known about the long-term (i.e., over decades) fate aquatic systems. Here, we show that most prescribed anxiolytic Sweden (oxazepam) persists its therapeutic form for several decades after being deposited a large freshwater lake. By comparing sediment cores collected 1995 2013, demonstrate oxazepam inputs from early 1970s remained sediments until sampling despite situ degradation...
Summary Climate change is expected to not only raise water temperatures, but also cause brownification of aquatic ecosystems via increased inputs terrestrial dissolved organic matter. While efforts have been made understand how temperature and separately influence food webs, their interactive effects less investigated. Further, although climate on likely will propagate consumers changes in insect emergence, this has rarely studied. We investigated the effect a large‐scale outdoor pond...
Major point sources of per- and polyfluoroalkyl substances (PFASs) cause ubiquitous spread PFASs in the environment.
The occurrence of per- and polyfluoroalkyl substances (PFASs) in aquatic ecosystems is a global concern because their persistence, potential bioaccumulation, toxicity. In this study, we investigated PFAS-contaminated pond Sweden to assess the cross-boundary transfer PFASs from environment riparian zone via emergent insects. Aquatic terrestrial invertebrates, surface water, sediments, soils, plants were analyzed for 24 including branched isomers. Stable isotope analysis carbon nitrogen was...
Over the past half century, ecologists have tried to unravel factors that drive species richness patterns in ecological communities. One influential theory is island biogeography (IBT), which predicts or habitat area and isolation are drivers of richness. However, relatively few studies testing IBT considered invertebrate belowground communities, it unclear as whether predictions made by hold for these Other theories predict characteristics such vegetation diversity may be important To...
Litter decomposition is an important driver of terrestrial systems, and factors that determine rate for individual litter species have been widely studied. Fewer studies explored the regulate how mixing litters multiple affects nutrient dynamics, only a handful investigated litter‐mixing effects may differ among different habitats or ecosystems, they respond to environmental gradients. We used well‐established retrogressive chronosequence involving thirty lake islands in northern Sweden...
Abstract Although the importance of stream condition for leaf litter decomposition has been extensively studied, little is known about how processing rates change in response to altered riparian vegetation community composition. We investigated patterns plant input and across 20 boreal headwater streams that varied proportions deciduous coniferous trees. measured a suite in‐stream physical chemical characteristics, as well amount type inputs from vegetation, related these native (alder,...
Abstract We examine how levels of multiple ecosystem services (ESs) change with succession in forests different tree species composition. More specifically we ask age interacts environmental conditions to regulate ES delivery. Using the nationwide Swedish forest inventory, comprising boreal and temperate regions, investigated six provisioning, regulating, recreational, and/or cultural ESs changed (10–185 years) stands also tested whether number delivered (i.e. multifunctionality)...
Land use is known to alter the nature of land–water interactions, but potential effects widespread forest management on headwaters in boreal regions remain poorly understood. We evaluated importance catchment land use, cover, and local stream variables for macroinvertebrate community functional trait diversity 18 headwater streams. Variation metrics was often best explained by in-stream variables, primarily water chemistry (e.g. pH). However, variation was, turn, significantly associated...
Behavioral assays constitute important research tools when assessing how fish respond to environmental change. However, it is unclear behavioral modifications recorded in laboratory are expressed natural ecosystems, a limitation that makes difficult evaluate the predictive power of laboratory-based measurements. In this study, we hypothesized exposure benzodiazepine (i.e., oxazepam) increases boldness and activity as well field – is, results can be used predict results. Moreover, expected...
