Abstract Agricultural land covers approximately 40% of Earth’s surface and affects hydromorphological, biogeochemical ecological characteristics fluvial networks. In the northern temperate region, agriculture also strongly amount molecular composition dissolved organic matter (DOM), which constitutes main vector carbon transport from soils to networks sea is involved in a large variety processes. Here, we provide first evidence about wider occurrence agricultural impacts on concentration DOM...
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...
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...
Abstract. Dissolved organic matter (DOM) is an important factor in aquatic ecosystems, which involved a large variety of biogeochemical and ecological processes, recent literature suggests that it could be strongly affected by agriculture different climates. Based on novel monitoring techniques, we investigated the interaction climate effects DOM quantity quality. To examine this, took water samples over 2 years two paired intensive extensive farming catchments each Denmark (temperate...
The relationships between fish composition, connectivity and morphometry of 103 lagoons in nine freshwater ecoregions (FEOW) 2·83° S 37·64° were evaluated order to detect possible congruence the gradient species richness similarities assemblage composition. Most included study <2 km(2) , with a maximum 3975 surface area. Combined area all was 5411 . Number varied locally from one 76. A multiple regression revealed that latitude, attributes connectivity, sampling effort explained large amount...
Abstract. Climate and hydrology are relevant control factors determining the timing amount of nutrient losses from land to downstream aquatic systems, in particular phosphorus (P) agricultural lands. The main objective study was evaluate differences P export patterns performance alternative monitoring strategies streams under contrasting climate-driven flow regimes. We compared a set paired draining lowland micro-catchments temperate climate stable discharge conditions (Denmark) sub-tropical...
Physical-chemical and biologicaldiversity of streams are influenced by the land use in their watersheds. Plastics currently make up most important waste asset, representing an part transported accumulated material water courses. This work analyzes consumption plastics debris fish communities with two contrasting types use. We worked threestreams impacted urbanization threeby extensive ranching. The stomach intestinal contents 309 individuals 29 species were analyzed, a modified alkaline...
Nitrogen lost from agriculture has altered the geochemistry of biosphere, with pronounced impacts on aquatic ecosystems. We aim to elucidate patterns and driving factors behind N fluxes in lowland stream ecosystems differing about land-use climatic-hydrological conditions. The climate-hydrology areas represented humid cold temperate/stable discharge conditions, subtropical climate/flashy Three complementary monitoring sampling characteristics were selected, including a total 43 streams under...
Asymmetries in bilateral organisms attract a lot of curiosity given that they are conspicuous departures from the norm. They allow investigation integration at different levels biological organization. Here we study whether and how behavioral asymmetrical anatomical traits co-evolved work together. We ask if asymmetry is determined locally for each trait or whole individual level species bearing genitalia. Asymmetric genitalia evolved many species; however, most cases direction fixed....
