Within mono-specific meadows of clonal plants, genotypic diversity may functionally replace species diversity. Little is known about the variability in performance and plasticity of different genotypes towards anthropogenically induced stressors. In this field experiment we compared light-limitation stress responses and recovery of different eelgra...

In species-poor communities, genetic diversity potentially plays an important role for ecosystem functioning, though this is still largely unexplored in marine and estuarine ecosystems. We studied how genetic diversity (sensu genotypic diversity and/or allelic richness) affects ecosystem functioning in marine habitat-forming plant communities. Firs...

The enemy release hypothesis predicts that nonindigenous species (NIS) are released from natural enemies (e.g. grazers etc.) in their new environment, thus facilitating invasion. Sargassum muticum is a conspicuous and successful invasive brown alga and several studies have investigated whether native herbivores feed less on S. muticum relative to n...

Predicting climate change‐mediated environmental effects on organisms is difficult because their direction and strength may depend on multiple ecological factors that vary in nature. This is because the effects of environmental factors often interact. One potentially important factor modifying organisms' thermal performance is their resource level....

Eutrophication is a strong driver that modifies coastal areas globally and measures to reduce nutrient input are implemented in many areas. As nutrient concentrations in coastal waters can vary drastically with time and space, quantifying the impacts of the actions taken to reduce eutrophication can be logistically challenging. In this study, we as...

Fucus vesiculosus (here Fucus) is a key species on rocky shores of the Baltic Sea, providing habitat for a diverse invertebrate community. While the invertebrate species within Fucus belts and their general distribution in the Baltic Sea are well known, much less is known about variation in invertebrate abundances and in community composition on di...

The immune system is costly to maintain and use because it requires a lot of energy. This can make parasite resistance dependent on host nutritional state. The dependence of immune function on host condition can have broad ecological (e.g., disease dynamics) and evolutionary (e.g., expression of trade‐offs related to parasite resistance) consequenc...

The non-indigenous tanaidacean crustacean Sinelobus vanhaareni Bamber, 2014 was first found in northern Europe in 2006 and has since spread to the northern Baltic Sea. Here, we surveyed the distribution of the species in different habitats in southwestern Finland, focusing on vegetated macroalgal and seagrass habitats (i.e., Fucus vesiculosus beds...

Understanding the ecological interactions that enhance the resilience of threatened ecosystems is essential in assuring their conservation and restoration. Top‐down trophic interactions can increase resilience to bottom‐up nutrient enrichment, however, as many seagrass ecosystems are threatened by both eutrophication and trophic modifications, unde...

Background Host immune function can contribute to numerous ecological/evolutionary processes. Ecoimmunological studies, however, typically use one/few phenotypic immune assays and thus do not consider the complexity of the immune system. Therefore, “omics” resources that allow quantifying immune activity across multiple pathways are needed for ecoi...

Effects of climate change on natural ecosystems can be mediated by ecological processes, but also by rapid evolutionary adaptations and/or non‐heritable trait changes in organisms. So far, most studies testing the importance of inter‐ versus intraspecific changes for how communities and their functioning responds to climate change are either short‐...

Abstract The growing threat of global climate change has led to a profusion of studies examining the effects of warming on biota. Despite the potential importance of natural variability such as diurnal temperature fluctuations, most experimental studies on warming are conducted under stable temperatures. Here, we investigated whether the responses...

Fucus radicans is an endemic habitat-forming brown macroalga in the Baltic Sea that commonly complements its sexual reproduction with asexual reproduction. Asexual reproduction in F. radicans takes place through formation of adventitious branches (hereafter fragments), but the exact mechanisms behind it remain unknown. We assessed experimentally th...

Ecosystems face multiple anthropogenic threats globally, and the effects of these environmental stressors range from individual‐level organismal responses to altered system functioning. Understanding the combined effects of stressors on process rates mediated by individuals in ecosystems would greatly improve our ability to predict organismal multi...

Multiple anthropogenic changes, such as climate change and chemical pollution, threaten the persistence of natural populations. Yet, their potential additive and interactive effects on organismal performance and fitness are poorly understood, thus limiting our ability to predict the effects of the global change. We conducted a laboratory experiment...

Climate change intensifies the frequency and intensity of rainfall events, which increases the discharge of freshwater and nutrients to coastal areas. This may lower salinity and increase nutrient availability and, thus, affect estuarine eelgrass populations. We studied the interactive effect of increasing NH4+ levels and low salinity on estuarine...

The macrofaunal colonization of isolated habitats is affected by many factors, ranging from distance to the nearest source population to the dispersal mechanism of the species. We investigated the initial epifaunal colonization at two sites, one situated in the Northern Gulf of Mexico and the other in the Northern Baltic Sea. At each site, artifici...

Research on plant biodiversity and ecosystem functioning has mainly focused on terrestrial ecosystems, and our understanding of how plant species diversity and interactions affect processes in marine ecosystems is still limited. To investigate if plant species richness and composition influence plant productivity in brackish water angiosperm commun...
