Cold-water coral reefs and sponge grounds are deep-sea biological hotspots, equivalent to shallow-water tropical coral reefs. In tropical ecosystems, biodiversity and productivity are maintained through efficient recycling pathways, such as the sponge loop. In this pathway, encrusting sponges recycle dissolved organic matter (DOM) into particulate...
Article
Full-text available
Aquatic ecosystems are affected by multiple environmental stressors across spatial and temporal scales. Yet the nature of stressor interactions and stressor-response relationships is still poorly understood. This hampers the selection of appropriate restoration measures. Hence, there is a need to understand how ecosystems respond to multiple stress...

Community classification enables us to simplify, communicate, track and assess complex distribution patterns. Yet, the distribution of organisms may not coincide with predefined geographical and environmental boundaries, and therefore, biology itself should be leading the classification. In this study, we showed how to arrive at such a biology-base...
Article
Water bodies in densely populated lowland areas are commonly affected by pollution from agricultural activities and wastewater treatment plant (WWTP) discharges, yet the selection of appropriate water quality assessment methods for these water bodies is under debate. Therefore, we aimed to 1) compare the ability of structural and functional metrics...
Article
Freshwater ecosystems have been degraded by multiple stressors. To mitigate the effects of multiple stressors on freshwater ecosystems, we must assess the current ecological condition of these systems, diagnose the cause of the environmental impact, and predict how they will respond to future changes in anthropogenic pressures. Most biomonitoring p...
Article
Past research has examined how anthropogenic stressors affect both structural and functional attributes of stream ecosystems. Nevertheless, biomonitoring programs rely mostly on structural metrics for surface-water quality and status assessments, and few studies have examined the extent to which functional metrics can strengthen these structure-bas...

• Aquatic macrophytes can have a significant impact on their associated community of epiphytic algae and bacteria through the provisioning of structural habitat complexity through different growth forms, the exudation of nutrients and the release of allelochemicals. In turn, this effect on epiphytic biofilm biomass and nutrient content has a potent...
Article
Full-text available
The process of macroinvertebrate drift in freshwater lowland streams is characterized by dislodgement, drift distance and subsequent return to the bottom. Refuges are important to all drift phases, since they may help larvae to avoid dislodgement and to escape from drift, even more so if the refuge structure is complex and heterogeneous. The aim of...
