The present study the environmental problems of invasive alien species, and shows from a legal perspective, the foundation provided by the Constitution of the Republic, and the main international agreements, to understand the state of the legislation of Uruguay in relation to these species, considering that they alter the ecological balance and cau...
The decline of amphibians is a current concern, with the presence of invasive alien species (IAS) being one of the main threats to biodiversity. In Uruguay, one of the IAS that affects native biodiversity is the invasive exotic anuran Aquarana catesbeiana (bullfrog), invading more than 60 ponds in three locations. The present work proposes the analy...
Dubiaranea magatama Cajade, Hagopián & Rodrigues n. sp. is described from Uruguay, and southern Brazil based on males and females from several types of native forests, and a potential distribution for this species is modeled. The predicted model for this species indicates a Pampean province and southern Atlantic Forest biome distribution. Three var...
La rana toro –Aquarana catesbeiana– fue introducida voluntariamente en Uruguay en 1986 con fines de cría para consumo humano. Su producción en cautiverio no fue viable económicamente y el abandono de la producción promovió la liberación accidental o deliberada de diversos ejemplares. Estos organismos llegaron a ambientes naturales y seminaturales,...
Background
Experts use knowledge to infer the distribution of species based on fuzzy logical assumptions about the relationship between species and the environment. Thus, expert knowledge is amenable to fuzzy logic modelling, which give to propositions a continuous truth value between 0 and 1. In species distribution modelling, fuzzy logic may also...
‘Rewilding’ is a nature conservation strategy gaining prominence worldwide. Established in the Northern Hemisphere, rewilding initiatives have increasingly been proposed in Argentina, but their relative merits, feasibility of implementation and accountability have lacked adequate analysis and discussion. Recently, 125
scientists and practitioners w...
The conservation of biodiversity in urban environ- ments has acquired importance in recent years. The fauna and flora in these environments are es- sential to contribute to their environmental qua- lity. In particular, birds are good bioindicators of the quality of the urban environment. This study was carried out within the framework of the Bio- g...
En los últimos años se han desarrollado en Argentina distintas intervenciones relacionadas con el rewilding (o re-asilvestramiento), abarcando una variedad de especies (e.g., grandes carnívoros, ungulados, psitácidos) y ecorregiones (e.g., Chaco Húmedo y Seco, Estepa Patagónica). El reasilvestramiento es definido como una estrategia aplicada en el...
Hantaviruses are the causative agents of hantavirus pulmonary syndrome (HPS) in the Americas. In Central and South America, 28 hantavirus lineages were associated with different Sigmodontinae rodents. Of these, Lechiguanas hantavirus was initially described as a lineage associated with HPS cases in the central region of Argentina. Initial studies o...
Riparian systems are highly threatened by alterations in its hydrological regimen and biological invasions. To guide its conservation is important to understand the relationships established between biological invasions and abiotic conditions affected by the hydrological regimen. We analyze the relationship between the distribution pattern of soil...
The sexual species of the Dilatata complex (Paspalum dasypleurum, P. flavescens, P. plurinerve, P. vacarianum, and P. urvillei) are closely related phylogenetically and show allopatric distributions, except P. urvillei. These species show microhabitat similarities and differences in germination traits. We integrated species distribution models (SDM...

The genus Mastophora Holmberg, 1876 is represented by 50 species that are distributed mainly in America and the Antilles. Males are much smaller than females and are not described in more than half of the known species of the genus. The high specificity of their diet (moths) and the technique which females use to capture their prey have been record...
Native to the southeastern United States, the honey locust (Gleditsia triacanthos) is an invasive tree in several South American countries. Since eradication of invasive species is often costly, prevention is a better strategy. The relationship between invasive species and their habitats can be analyzed using species distribution models to produce...
Metapopulation theory considers that the populations of many species are fragmented into patches connected by the migration of individuals through an interterritorial matrix. We applied fuzzy set theory and environmental favorability (F) functions to reveal the metapopulational structure of the 222 butterfly species in the Iberian Peninsula. We use...
Praying mantises (Order Mantodea) are charismatic insects thanks to their diverse and peculiar appearance and
surprising behaviors. However, studies on this order are scarce, particularly in the Southern Neotropical Region. Here we
present the first catalogue of praying mantises from Uruguay. We revised Mantodea specimens deposited at Colección...
Ecoregions and areas of endemism are central concepts in biogeography. Based on collection records and the Endemic Analyses implemented with NDM/VNDM method we analyzed fish areas of endemism in the junction of three freshwater ecoregions related to the Rio de la Plata estuary (Lower Parana, Lower Uruguay, Laguna dos Patos) in Southern Neotropical...
In previous studies, Uruguay has been considered a biogeographical crossroads. Paso Centurión and Sierra de Ríos in eastern Uruguay were recently entered into the National System of Protected Areas. The landscape is characterized by a mosaic of different ecosystems located in one of the dendrofloristic hotspots proposed for the country. The spiders...
Control and eradication of invasive species are costly measures with little chance of success. The Strategic Plan for Biological Diversity (2011-2020) as part of the “Aichi goals” proposed identifying exotic species with invasive potential and establishing measures to manage their introduction routes and avoid their establishment. To achieve these...
Latica galeanoi, the sole species in a new genus within Gnaphosidae, is described from Uruguay and Argentina based on morphological, molecular and biogeographic data. The genus is sister to the rest of the Herpyllinae subfamily. The delimitation of this new genus is supported by various plesiomorphic and synapomorphic characters, which represents h...
La coloración atípica en los anfibios es un fenómeno raro que a veces ocurre en la naturaleza. Se encontró un espécimen de tono azul brillante de Phiyllomedusa ihereingii durante una sesión de encuestas en Maldonado, Uruguay. Esta coloración responde a una mutación genética que altera la producción de pigmentos amarillos y que podría estar indicand...
The maned wolf, the largest canid in South America, was originally distributed in areas with open natural vegetation in the Cerrado biome, Chaco and Pampas regions. The dynamics of its distribution are, however, in flux, with populations declining at the southern limit of its distribution, and areas of apparent range expansion in Brazil. Although t...

They are zoonotic viruses which...
In the current South American epidemiological framework, describing the biogeographic interactions between vectors and diseases is a priority. In order to prevent and fight against outbreaks, it is necessary to understand the factors affecting both the vectors and the dengue virus. The geographic range occupied by Aedes mosquitoes (A. aegypti and A...
The purple pampas grass is an endemic species of the Andes with invasive stages in Australia, New Zealand, South Africa and western North America. Species Distribution Models are a common tool to predict the potential distribution of species. In the case of invasive species it is unclear if their potential distributions in new invaded areas depend...
EL aguará guazú, o lobo de crin (Chrysocyon brachyurus), es el mayor cánido de América del Sur. Históricamente la especie se hallaba en seis países: Argentina, Bolivia, Brasil, Paraguay, Perú y Uruguay. Hoy, en cambio, está catalogada como casi amenazada por la Unión Internacional para la Conservación de la Naturaleza, porque está sufriendo una cla...
The maned wolf is the largest canid in South America, and is currently classified as a near threatened species. Though once widely distributed in open habitats throughout the continent, the species’ current distribution is significantly reduced, especially in the southern part of its range. Species distribution models are useful tools that can reve...
Historically there has been taxonomic confusion among some Lygophis and Erythrolamprus species (previously belonging to the genus Liophis) due to their high similarity in color and general body form, in addition to a lack of understanding of their natural history and distribution. Lygophis anomalus is a common snake thought to be widely distributed...

Harvestmen are a good taxon for biogeographic studies due to their low vagility and their dependence on environmental conditions which make most of them live in humid and shaded habitats. Current knowledge of the geographical distribution of Uruguayan opiliofauna suggests that no evident zoogeographic areas are present, mainly because of the appare...
Un atlas de distribución es un documento cartográfico que recoge la distribución espacial de las especies de un taxón en un determinado territorio como resultado de un muestreo exhaustivo. La confección de los atlas constituye un fin en sí mismo, por su contribución a la corología de las especies y, a la vez, representan el punto de partida para la...
We analysed the main geographical trends of terrestrial mammal species richness (SR) in Argentina, assessing how broad-scale environmental variation (defined by climatic and topographic variables) and the spatial form of the country (defined by spatial filters based on spatial eigenvector mapping (SEVM)) influence the kinds and the numbers of mamma...
After being fed by their parents, Greater Flamingo chicks store food in their crops, which
protrude outwards. We allocated the crop profiles of chicks to four categories to assess the
relationship between body mass and crop profile variation, and so determine whether crop
size can be used as an accurate index of the amount of food ingested, and to...
