Abstract Shallow lakes, the most abundant lake type in world, are very sensitive to climatic changes. The structure and functioning of shallow lakes greatly impacted by submerged plants, these may be affected climate warming various, contrasting, ways. Following a space‐for‐time substitution approach, we aimed analyse role aquatic (submerged free‐floating) plants under warm climates. We introduced artificial free‐floating plant beds five comparable located temperate zone (Denmark, 55–57 °N)...
Summary 1. Structural complexity may stabilise predator–prey interactions and affect the outcome of trophic cascades by providing prey refuges. In deep lakes, vulnerable zooplankton move vertically to avoid fish predation. contrast, submerged plants often provide a diel refuge against predation for large‐bodied in shallow temperate with consequences whole ecosystem. 2. To test extent which macrophytes serve as refuges subtropical we introduced artificial plant beds into littoral area five...
Summary 1. Fish play a key role in the functioning of temperate shallow lakes by affecting nutrient exchange among habitats as well lake trophic structure and dynamics. These processes are, turn, strongly influenced abundance submerged macrophytes, because piscivorous fish are often abundant at high macrophyte density. Whether this applies to warmer climates is virtually unknown. 2. To compare community dynamics plant beds between subtropical we conducted experiments with artificial...
Abstract. Plastics have been found in several compartments Antarctica. However, there is currently no evidence of their presence on Antarctic glaciers. Our pilot study investigated plastic occurrence two ice surfaces (one area around Uruguay Lake and another one Ionosferico Lake) that constitute part the ablation zone Collins Glacier (King George Island, Antarctica). results showed expanded polystyrene (EPS) was ubiquitous, ranging from 0.17 to 0.33 items m−2, whereas polyester only surface...
Global change drivers including eutrophication, hydrological disturbance, climate change, chemical pollution, overexploitation, invasive species, and land-use are affecting the function structure of freshwater ecosystems. South American ecosystems especially threatened by combination rising human pressures on natural resources (i.e., water use, intensive agriculture, mining, deforestation, afforestation) lack adequate legislation economic for environmental protection restoration. We assess...
Abstract The role of multitrophic diversity in sustaining multiple functions simultaneously (multifunctionality) is still poorly understood natural communities, especially highly diverse aquatic ecosystems. Existing studies have focused on the effect single trophic group ecosystem function and individual functions, neglecting fact that groups are needed to maintain multifunctionality. Here, using a 16‐year database from tropical shallow lakes, we combined species richness nine into unique...
Human land-use change is a major threat to natural ecosystems worldwide. Nonetheless, the effects of human land-uses on structure plant and animal assemblages their functional characteristics need be better understood. Furthermore, pathways by which land uses affect ecosystem functions, such as biomass production, still clarified. We compiled unique dataset fish, arthropod macrophyte from 61 stream in two Neotropical biomes: Amazonian rainforest Uruguayan grasslands. then tested how cover...
Summary 1. Small cladocerans, copepod nauplii and rotifers often dominate the zooplankton community in tropical subtropical lakes. This is probably because of high predation pressure by small omnivorous–planktivorous fish, but experimental evidence scarce. 2. study used two approaches to test effect fish species Jenynsia multidentata , which frequently abundant (sub)tropical eutrophic lakes South America, on size distribution zooplankton. In Lake Blanca (Uruguay), lacks any piscivores, we...
In arid and semiarid regions, extreme temperature events the frequency duration of drought will increase toward 2050, leading to increased salinisation inland waters, aggravated by catchment erosion human activities (e.g., crop irrigation). With salinisation, a decline in biodiversity is expected, with potential negative effects on food web structure ecosystem dynamics. Our objective was assess changes community 24 lakes along wide salinity gradient (i.e., subsaline hypersaline) region...
