Habitat loss and human-caused mortality have led to an approximate 50% reduction of the distribution of the jaguar (Panthera onca). The large contraction in the jaguar’s occurrence points to a need to understand its population size and habitat preferences to apply to the species’ conservation. Typically, jaguar densities are estimated with capture–...
Aim
Land‐use change and overexploitation are major threats to biodiversity, and climate change will exert additional pressure in the 21st century. Although there are strong interactions between these threats, our understanding of the synergistic and compensatory effects on threatened species' range geography remains limited. Our aim was to disentan...
The gray brocket deer, Mazama gouazoubiraG. Fischer, 1814, occurs in South America and presents an extensive degree of morphological and genetic variability. Previous phylogenetic research showed that the genus Mazama is polyphyletic and imposed the designation of a different genus-group name for M. gouazoubira. We aimed to review and clarify the t...
The distribution of the jaguar has decreased by approximately 50% with its conservation highly dependent upon its persistence and mobility in anthropogenic landscapes. Consequently, understanding the effects of land use on jaguar populations and their connectivity is a necessary precursor for effective conservation of the species. We simultaneously...
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropica...
[Introducción]: El sistema de Áreas Protegidas del Paraguay fue creado por la Ley 352 en 1994 para poner orden el sistema del país. Desde 1954 se crearon un total de 102 áreas protegidas. La categoría con mayor cantidad es la “Reserva Natural” que cuadruplica a los Parques Nacionales y Monumentos Naturales. La medición del éxito del SINASIP fue pre...
This work presents the main biodiversity hotspots existing in the Paraguayan Chaco and is an update of the results obtained in the first Ecoregional Assessment of the Great American Chaco. These are the results of a series of workshops that included scientific and technical discussions carried out by local experts in zoology, botany, forestry, soil...
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across...

Redlist for threatened species of mammals of Paraguay. Chapter related to Carnivora species.
Redlist species of threatened mammals of Paraguay: Cetartiodactyla and Perissodactyla, ungulates.
Se evaluaron 179 especies, teniendo al tapiti Sylvilagus brasiliensis y al Dasypus septemcinctus como especies no evaluadas NE (ver capítulo Xenarthra). Entre las especies evaluadas, se resalta que 29 especies fueron catalogadas como Datos Insuficientes o DD, esto significa que la información disponible sobre estas especies en nuestro país es tan e...
We analyzed the distribution patterns of primates and their conservation status Alouatta caraya, Aotus azarae, Mico melanurus, Sapajus cay, and Callicebus pallescens in Paraguay. We employed a maximum likelihood estimator to understand species distributions based upon observational records. Threats and the presence of species in protected areas wer...
ABSTRACT The development of protected areas in Paraguay shows presents some basic conceptual problems. The defnition about what is a “Managed Resources Reserve” (RMM) is very confuse and contradictory in some in the established legal framework. This paper identifes the most important issues related to problems impeding progress to the suitable impl...
El pecarí del Chaco conocido localmente en Para-guay como tagua (Catagonus wagneri) es una es-pecie en peligro de extinción endémica del Chaco Americano, cuya situación se mantiene en dete-rioro como consecuencia de la pérdida y transfor-mación de su hábitat y de la caza excesiva en toda su área de distribución. Este trabajo presenta los resultados...
RESUMEN El Sur de Paraguay es una región cuyas características eco-regionales son confusas debido a su carácter ecotonal. Esta región corresponde a la transición del Bosque Pa-rananense que se proyecta desde el este y el Chaco Húmedo, que cubre los terrenos alu-viales bajos del Oeste. Su cobertura corres-ponde a sabanas herbáceas, principalmente de...
Abstract
The Chacoan peccary (Catagonus wagneri), or Tagua, an endemic species living in the Chaco ecoregion, is endangered by highly increasing deforestation rates across the region, particularly
in the last decade. This situation highlights the need to better understand the current distribution of the species, as well as how environmental conditi...
This classification is the same as that of the Brazilian official list of threatened fauna (Duarte et al. 2012).
This species is listed Vulnerable under A3cde because a population reduction of 30% is suspected for the
next three generations (15 years), and there is no perspective of cessation of the impacts that are
causing this reduction. This sus...
Understanding the fine-scale geographic distribution of a species has applications in biogeography, ecology, evolution and conservation. Species distribution models (SDM) have been widely used to predict geographic and climatic ranges of species. Geoffroy's cat Leopardus geoffroyi is a small felid of least concern that occupies a wide variety of ha...
The Gran Chaco is an ecoregion covering 1.5 million km 2 of Argentina, Bolivia and Paraguay and is considered one of the last "wilderness" areas in the Neotropics. Currently, the Paraguayan Gran Chaco is undergoing significant changes in land use consisting of deforestation for the creation of livestock pasture. This widespread deforestation and ha...
We document for the first time that Sciurus ignitus, a medium-sized agouti-patterned squirrel with white venter, occurs in Paraguay, being found in the northern Chaco-Pantanal region of the country, where the borders of Paraguay, Bolivia, and Brazil come together. Sciurus urucumus, the only species of squirrel previously known with certainty to ran...
Resumen
El Guaraní ha sido catalogado durante el largo periodo de la colonización sudamericana como la “lengua general”, tanto en las posesiones españolas como en las portuguesas a lo largo de un extenso territorio. Esto se refleja en la historia taxonómica de la mastozoofauna paraguaya, aún hoy día a través del uso cotidiano
de nombres comunes y u...
The Near Threatened maned wolf Chrysocyon brachyurus is a South American endemic canid occurring mainly in grassland-dominated regions. We compiled and mapped recent and historical data to compare the species’ present and historical distributions and propose hypotheses for range shifts. There has been recent range expansion in eastern Brazil associ...

I am working with biogeography of southern Paraguay and the info about Paraguay river evolution is relevant for my work. So, if someone could help me, I will be very gratefull! Specially, I have not any info about the Center and South Paraguay river evolution. Brazilian Pantanal and Formosa, Argentina, have information I already get, but nothing about paraguayan sections of actual river course.
Thanks
It is known the closely relationship between grasslands and herbivores community. But, I need some info about herbivory affects in grasslands, i.example, What happens when a specific herbivory community (as Forbs-eaters) is replaced by other (as grass-eaters). My question is regardins possibly changes of cervids and others forbs-eaters that have been repalced by cows and horses (more fiber eaters) in grasslands savannas.
Thanks!
