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...
Abstract The invasive Asian golden mussel Limnoperna fortunei is continuously expanding through South America, altering aquatic ecosystem structure and functioning. While several native fish species predate on this mussel, these interactions, their consequences for the food web, have not been studied in depth. We combine a survey of assemblage trophic using gut contents stable isotope analysis with an situ exclusion experiment order to: (a) determine main predating L. ; (b) estimate...
Abstract The flow of individuals among communities and their interactions with local environmental filters are increasingly recognised as determinants biodiversity patterns in riverine ecosystems. Both incoming dispersers conditions expected to systematically change along connectivity gradients from headwaters downstream communities. However, the interplay between isolation‐centrality structure function has seldom been considered. Here, we represented dendritic Negro River basin riverscape...
The Neotropics represent a hotspot for freshwater biodiversity with vast number of fish species scarce ecological knowledge. This holds true the Uruguay River, where assemblages and their diets remain unexplored. Fish were surveyed in 14 sites along river main course, from headwaters to mouth (approximately 1800 km), aim identify trophic roles fishes describe structure these assemblages, following standardized sampling campaigns laboratory procedures. One hundred (2309 gut contents) analysed...
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...
Abstract Unravelling the effect of climate variability on species biology has been one main goals ecological studies. Environmental factors such as river discharge and temperature have being proposed triggers reproductive cycle in fish. In temperate climates, fish reproduction is affected mainly by temperature, while influenced flood pulses large tropical rivers. We evaluated influence Iheringichthys labrosus’ . studied following variables: gonadosomatic index (GSI), hepatosomatic (HSI)...
The ecosystem effects of Limnoperna fortunei have been studied nationally in recent years. However, the interactions that this invader establishes with native benthic fauna not determined detail. objective study was to collect information on between golden mussel and macroinvertebrates Uruguay River, through (a) bibliographic survey, (b) photographic record obtained field (c) analysis data from an experiment colonization carried out previously rocky shores river. reported bibliography mainly...
Human land-use is changing Earth’s surface, causing a decline in biodiversity and altering ecosystem functioning. However, most of the empirical evidence impacts Neotropics comes from studies investigating isolated types, pathways by which intensified land-uses affect functioning are largely unknown. Using database 61 streams spanning two hyperdiverse Neotropical regions, we demonstrate that intensive human (agriculture, urbanization, pasture, afforestation) strongly stream We showed...
Abstract Genidens barbus is a vulnerable marine migrant catfish with low fecundity, complex life cycle (i.e. mouth breeding), and the target of industrial artisanal fisheries several countries. This species regularly migrates from to freshwater environments south‐western Atlantic. The aim this work was delve deeper into migration ecology G. , characterizing both its timing potential environmental drivers. Furthermore, aspects population structure reproduction migrants in lower Uruguay River...
Biodiversity loss is a global concern, and agriculture one of the economic sectors responsible for this impact. The assessment ecosystems under influence livestock production essential knowing their integrity ability to provide ecosystem services. aim investigation was evaluate application LEAP/FAO guidelines quantitative biodiversity in sector at local scale (farm level) group six study cases Uruguay. A set 20 indicators used, including seven key thematic issues: habitat protection, change,...
This work provides new length-weight information for seven species of freshwater fishes. The analyzed specimens were collected monthly during a year (April 2018–March 2019) in coastal lagoon system and its associated streams southern Uruguay. During each sampling campaign, fishes captured using gillnets the electrofishing streams. study reports maximum size four first relationship report Gymnogeophagus terrapurpura. Length-weight estimates their confidence intervals are provided all species.
