Riparian ecosystems harbour unique biodiversity because of their close interconnections with adjacent aquatic ecosystems. Yet, how aquatic ecosystems influence terrestrial biodiversity over different spatial scales is poorly understood, particularly in the tropics. We conducted field campaigns to collect 235 terrestrial invertebrate assemblages alo...
Permanent ponds are valuable freshwater systems and biodiversity hotspots. They provide diverse ecosystem services (ES), including water quality improvement and supply, food provisioning and biodiversity support. Aquatic subsidies provide a high nutritional quality, energy density and nutrient concentration. Among those, emerging insects are rich i...
Animal stoichiometry affects fundamental processes ranging from organismal physiology to global element cycles. However, it is unknown whether animal stoichiometry follows predictable scaling relationships with body mass and whether adaptation to life on land or water constrains patterns of elemental allocation. To test both interspecific and intra...
The influence of aquatic resource‐inputs on terrestrial communities is poorly understood, particularly in the tropics. We used stable isotope analysis of carbon and nitrogen to trace aquatic prey use and quantify the impact on trophic structure in 240 riparian arthropod communities in tropical and temperate forests. Riparian predators consumed more...
Aim: Emerging aquatic insects link aquatic and terrestrial ecosystems across the Earth. Their diversity, abundance and functional importance means their emergence is an important phenological event. Nevertheless, aquatic insect emergence is understudied at a global scale compared to other phenological events, despite changing phenology being one of...
Freshwaters are among the most vulnerable ecosystems to climate warming, with projected temperature increases over the coming decades leading to significant losses of aquatic biodiversity. Experimental studies that directly warm entire natural ecosystems in the tropics are needed, for understanding the disturbances on aquaticcommunities. Therefore,...
Permanent ponds are valuable freshwater systems and biodiversity hotspots. They provide diverse ecosystem services (ES), including water quality improvement and supply, food provisioning and biodiversity support. This is despite being under significant pressure from multiple anthropogenic stressors and the impacts of ongoing global change. However,...
Permanent ponds represent important habitats for aquatic biodiversity and provide vital
ecosystem services as key elements for blue landscape connectivity. Although mostly
neglected in management programmes, protection schemes and biodiversity studies in
general, ponds constitute habitats with high α- and spatial β-diversity, providing unique
habit...
Ponds, whilst being mostly neglected in management and protection plans, can constitute habitats with high α- and β-diversity, including many rare and endemic species. In heterogeneous landscapes, ponds can also contribute to habitat connectivity and enhance γ-diversity whilst delivering many ecosystem services. Semi-aquatic insects are one of the...
Whilst being small and shallow, permanent ponds provide valuable habitats for a multitude
of organisms as well as provide habitats for animals like aquatic insects and others,
including many rare species. These ponds, which were often neglected in limnological
studies, were the core of our joint project, the 3rd freshwater project - EUROPONDS in or...
Within the EUROPONDS project we looked into the contribution of aquatic invertebrates to terrestrial ecosystems, which are globally declining, in various countries all over Europe. Our study encompassed a restored quarry in Alpedrete, Madrid, Spain, a landscape destined for livestock activities. We hypothesized that the emergence during autumn and...
Insect abundance and diversity are declining worldwide. Although recent research found freshwater insect populations to be increasing in some regions, there is a critical lack of data from tropical and subtropical regions. Here, we examine a 20-year monitoring dataset of freshwater insects from a subtropical floodplain comprising a diverse suite of...
Aquatic ecosystems are tightly linked to terrestrial ecosystems by exchanges of resources, which influence species interactions, community dynamics and functioning in both ecosystem types. However, our understanding of how this coupling responds to climate warming is restricted to temperate, boreal and arctic regions, with limited knowledge from tr...
Long-term monitoring of host-parasite interactions is important for understanding the consequences of infection on host fitness and population dynamics. In an eight-year survey of the loggerhead sea turtle ( Caretta caretta ) population nesting in Cabo Verde, we determined the spatiotemporal variation of Ozobranchus margoi , a sanguivorous leech be...
