Abstract Carpobrotus edulis , a highly invasive plant species repeatedly introduced along the Atlantic coast of South America, poses significant threat to ecological integrity coastal dune ecosystems in Uruguay. This study used 15 years iNaturalist records assess magnitude invasion, focusing on its distribution, abundance, and reproductive phenology. Through analysis georeferenced dated data, we determined that has spread extensively, covering 10-km-wide area occupying approximately 220 km...
Abstract Body size is a key trait in ecology due to its influence on metabolism and many other life‐history traits that affect population community responses environmental variation as well ecosystem properties. The spectrum represents the relationship between abundance (or biomass) body size, independent of species identity. Size parameters, such slope or intercept, have been applied extensively indicators ecological status across multiple types. GLOSSAQUA dataset includes data from mainly...
A new species of Austrolebias is described based on individuals from the middle and upper río Negro (río Uruguay basin) Yaguarón (Patos-Merín system). The can be differentiated all other genus by unique presence in males uniform bluish gray pigmentation flanks (without vertical bands) unpaired fins. also distinguished combination characters associated with a reduction squamation abdominal, preopercular, opercular regions. presents some morphological characteristics similar to A. gymnoventris...
Body size may be more important than species identity in determining interactions and community structure. However, co-occurrence of organisms has commonly been analysed from a taxonomic perspective the body is rarely taken into account. On six sampling occasions, we patterns killifish co-occurrences nestedness (tendency for less rich communities to subsamples richest), checkerboard structure segregation), modularity groups co-occur frequently random expectation) pond metacommunity located...
Based on National Collections records, this article presents the first report of eight freshwater fish species for Uruguay in middle and lower River basin, extending their current distribution: Cyanocharax alegretensis Malabarba Weitzman, 2003; Leporinus lacustris Amaral Campos, 1945; Microglanis aff. eurystoma Mahler, 1998; Tatia boemia Koch Reis, 1996; Lepthoplosternum pectorale (Boulenger, 1895); Crenicichla missioneira Lucena Kullander, 1992; C. minuano Apistogramma borellii Regan, 1906....
ABSTRACT We describe a new species of substrate-brooding Gymnogeophagus , based on coloration characters. The can be distinguished from the remaining in genus by unique pigmentation dorsal fin which consists light blue, diagonal stripes over red background spiny section and combination round, elliptic, elongated bright blue spots soft section. It further all other following characters: discontinuous band above upper lateral line humeral area, roundish to orange anal fin, conspicuous...
Temporary ponds of Uruguay and the invertebrates that inhabit them represent relatively unexplored ecosystems, without clear references in relation to diversity levels they host. In present work we report presence 216 species morphospecies a total estimate richness between 263 373 species, for 18 temporary Castillos Lagoon Basin, department Rocha, Uruguay. This high would allow maintaining stability ecosystem functioning services it provides, such as drinking water, attenuation hydrological...
In this article the authors present first report of four characiform fish species for Uruguay, extending their current distribution to middle and lower Uruguay River basin: Astyanax saguazu Casciotta, Almirón Azpelicueta, 2003; Hypobrycon poi Almirón, Azpelicueta Cione, 2001; Leporinus amae Gody, 1980; Cyphocharax saladensis (Meinken, 1933). These were previously recorded from either upper River, Patos-Merín lagoon system or Paraná River. Color pattern in life A. H. are described time.
Esta investigación describe la comunidad de aves que habita en los palmares Butiá (Butia odorata), Rocha, Uruguay, un ecosistema singular destacado valor paisajístico, ecológico y cultural. Durante el período estudio, entre octubre 2018 mayo 2023, se utilizaron diferentes técnicas muestreo como puntos conteo, transectos colocación cámaras trampa, con fin recabar información sobre las especies habitan este ambiente. Estas metodologías permitieron identificar 86 aves, clasificadas 19 órdenes...
