The IUCN/SSC Canid Specialist Group / Canid Species Accounts. The fauna and flora of South America are remarkable for their endemism. The canids of South America are no exception. There are 10 canid species found here, of which 9 are endemic. The 10th species, the gray fox, occurs mainly in North and Central America, extending its range only into northern South America.. The majority of canids found in South America are commonly referred to as "foxes". However, to distinguish the endemic South American Pseudalopex spp. (formerly Dusicyon) and Cerdocyon thous, we refer to these by their Spanish name "zorro". The zorros are found in every habitat on the continent, from the coastal deserts (Sechuran zorro), to the open savanna (grey zorro, culpeo, Azaras zorros). While elsewhere (Asia, Africa) canids invariably shun the rain forest, one species of South American zorro is found in the rain forests (small-eared zorro) and another (the crab-eating zorro) inhabits coastal and lowland forests.

This study examines a genome-wide dataset of 678 Short Tandem Repeat loci characterized in 444 individuals representing 29 Native American populations as well as the Tundra Netsi and Yakut populations from Siberia. Using these data, the study tests four current hypotheses regarding the hierarchical distribution of neutral genetic variation in native South American populations: (1) the western region of South America harbors more variation than the eastern region of South America, (2) Central American and western South American populations cluster exclusively, (3) populations speaking the Chibchan-Paezan and Equatorial-Tucanoan language stock emerge as a group within an otherwise South American clade, (4) Chibchan-Paezan populations in Central America emerge together at the tips of the Chibchan-Paezan cluster. This study finds that hierarchical models with the best fit place Central American populations, and populations speaking the Chibchan-Paezan language stock, at a basal position or separated ...

This selective review of the Quaternary paleoclimate of the South American summer monsoon (SASM) domain presents viewpoints regarding a range of key issues in the field, many of which are unresolved and some of which are controversial. (1) El Niño-Southern Oscillation variability, while the most important global-scale mode of interannual climate variation, is insufficient to explain most of the variation of tropical South American climate observed in both the instrumental and the paleoclimate records. (2) Significant climate variation in tropical South America occurs on seasonal to orbital (i.e. multi-millennial) time scales as a result of sea-surface temperature (SST) variation and ocean-atmosphere interactions of the tropical Atlantic. (3) Decadal-scale climate variability, linked with this tropical Atlantic variability, has been a persistent characteristic of climate in tropical South America for at least the past half millennium, and likely, far beyond. (4) Centennial-to-millennial climate ...
Historically, most T. cruzi DTUs have had broadly distinct, but often overlapping, geographic and ecologic distributions (2). TcV and TcVI are largely confined to domestic transmission cycles and are sympatric with severe chronic and congenital human disease in southern South America (2). Increased sampling indicates that the geographic ranges of TcV and TcVI are more extensive than previously suggested. Putative domestic hybrid strains were identified recently as far north as Colombia (5); it is unclear whether these are bona fide TcV and TcVI isolates (suggesting long-range introduction) or progeny of a novel, independent, and local recombination event(s). Elucidation of the molecular epidemiology of TcV and TcVI has been complicated by limited sample collections and difficulties distinguishing these genotypes from their parental DTUs (6) and each other (7). We undertook high-resolution nuclear and mitochondrial genotyping of hybrid clones from Colombia to resolve their putative status as ...
In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South America, Central America, the Caribbean islands, and southern North America. In Mexico, the Yucatán Peninsula and southern lowlands, and most of the east and west coastlines, including the southern tip of the Baja California Peninsula are Neotropical. In the United States southern Florida and the coastal portion of the Rio Grande Valley in South Texas may be considered Neotropical. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct from the Nearctic realm (which includes most of North America) because of the long separation of the two continents. The formation of the Isthmus of Panama joined the two continents two to three million years ago, ...
Origins of agriculture - The Americas: Indigenous peoples in the Americas created a variety of agricultural systems that were suited to a wide range of environments, from southern Canada to southern South America and from high elevations in the Andes to the lowlands of the Amazon River. Agriculture arose independently in at least three regions: South America, Mesoamerica, and eastern North America. Although the Americas had several indigenous animal species that were domesticated, none were of an appropriate size or temperament for use as draft animals; as a result, the plow and other technology reliant on heavy traction were unknown. Swidden production, also known as slash-and-burn
Abstract:. Ultraviolet radiation (UVR) plays a key role in several biological functions, including human health. Skin exposure to UVR is the main factor in vitamin D photoconversion. There is also evidence relating low levels of vitamin D with certain internal cancers, mainly colon, breast and prostate, as well as other diseases. Several epidemiological studies have shown an inverse relationship between the above-mentioned diseases and latitude, in accordance with the ultraviolet radiation latitudinal gradient. The aim of this study is to determine whether UV irradiance levels in the southern South America are sufficient to produce suitable levels of vitamin D year around. For this purpose, vitamin D photoconversion weighted-irradiance was analyzed between S.S. de Jujuy (24.17°S, 65.02°W) and Ushuaia (54° 50′S, 68° 18′W). In addition to irradiance, skin type and area of body exposed to sunlight are critical factors in vitamin D epidemiology. Due to a broad ethnic variability, it was ...

In biogeography, the Neotropic or Neotropical realm is one of the eight terrestrial realms. This realm includes South and Central America, and in North America the southern Mexican lowlands, the Caribbean islands, southern Florida, and the coastal portion of the Río Grande Valley in South Texas because these regions share a large number of plant and animal groups.. The realm also includes temperate southern South America. In contrast, the Neotropical Floristic Kingdom excludes southernmost South America, which instead is placed in the Antarctic kingdom.. The Neotropic is delimited by similarities in fauna or flora. Its fauna and flora are distinct from the Nearctic (which includes most of North America) because of the long separation of the two continents. The formation of the Isthmus of Panama joined the two continents two to three million years ago, precipitating the Great American Interchange, an important biogeographical event.. The Neotropic includes more tropical rainforest (tropical and ...

We assessed the influence of the marine diazotrophic cyanobacterium Trichodesmium on the bio-optical properties of western tropical South Pacific (WTSP) waters (18-22 degrees S, 160 degrees E-160 degrees W) during the February-March 2015 OUTPACE cruise. We performed measurements of backscattering and absorption coefficients, irradiance, and radiance in the euphotic zone with a Satlantic MicroPro free-fall profiler and took Underwater Vision Profiler 5 (UPV5) pictures for counting the largest Trichodesmium spp. colonies. Pigment concentrations were determined by fluorimetry and high-performance liquid chromatography and picoplankton abundance by flow cytometry. Trichome concentration was estimated from pigment algorithms and validated by surface visual counts. The abundance of large colonies counted by the UVP5 (maximum 7093 colonies m(-3)) was well correlated to the trichome concentrations (maximum 2093 trichomes L-1) with an aggregation factor of 600. In the Melanesian archipelago, a maximum of ...

As with most World Books for Rifts, the South America outing does its best to distill the rich heritage and culture of a region into a series of types of power armor and breeds of mutants, to which it then adds a whole lot of nonsense about bug monsters and dinosaurs. It doesnt quite count as cultural appropriation when there is a vampire gaucho fighting a mechanical t-rex ...

During the last 7 Ma, South Americas terrestrial predator guild has changed from one composed almost entirely of nonplacental mammals (metatherians), birds, and reptiles to one dominated by immigrant placental carnivorans (with a few small marsupial and avian predators like didelphine opossums and seriemas). It was originally thought that the native South American predator guild, including sparassodonts, carnivorous opossums like Thylophorops and Hyperdidelphys, armadillos such as Macroeuphractus, terror birds, and teratorns, as well as early-arriving immigrant Cyonasua-group procyonids, were driven to extinction during the GABI by competitive exclusion from immigrating placental carnivorans, and that this turnover was abrupt.[94][95] However, the turnover of South Americas predator guild was more complex, with competition only playing a limited role. In the case of sparassodonts and carnivorans, which has been the most heavily studied, little evidence shows that sparassodonts even encountered ...
... , Phylogeography and Mollecular Markers. Marc J. Bechard1, Jose H. Sarasola2 and Andreas J. Helbig3 (Oral). Comparison of Morphometric Measurements of male and female Spot-winged Falconets sexed using PCR Amplification Methods. The Spot-winged Falconet (Spiziapteryx circumcinctus) is a little-known Neotropical falconid endemic to southern South America. Few data exist on the morphology of the species. Only a handful of specimens have been obtained to take morphometric measurements and the degree to which sexual dimorphism has developed in the species is largely unknown. Information on the latter would perhaps enable the sexing of individuals in the hand. In an effort to provide such data, we captured 25 falconets using bal-chatri traps with various mouse and bird lures in La Pampa, Argentina between 1998-2001. We measured body mass, wingspan, wing chord, tail length, total body length, culmen length, tarsus length and width, and hallux length, and obtained blood samples using standard ...

This chunky shorebird has a rather anonymous look in winter plumage, but is unmistakable in spring, when it wears robin-red on its chest. It nests in the far north, mostly well above the Arctic Circle (the first known nest was discovered during Admiral Pearys expedition to the North Pole in 1909); its winter range includes shorelines around the world, south to Australia and southern South America. Where it is common, the Red Knot may roost in very densely packed flocks, standing shoulder to shoulder on the sand.
Cortaderia selloana, commonly known as pampas grass,[1] is a flowering plant native to southern South America, including the Pampas region after which it is named. There are around 25 species in the genus Cortaderia.. It is a tall grass, growing in dense tussocks that can reach a height of 3 m (10 ft). The leaves are long and slender, 1-2 m (3 ft 3 in-6 ft 7 in) long, and 1 cm broad, with very sharp edges. The leaves are usually bluish-green, but can be silvery grey. The flowers are produced in a dense white panicle 20-40 cm (8-16 in) long on a 2-3 m (6 ft 7 in-9 ft 10 in) tall stem.. ...

The Central/South American population is growing rapidly in the U.S., but little is known about the health status. The purpose of this study was 1) to estimate the prevalence of MS and its individual components, 2) compare risk factors among Hispanic sub-groups, and 3) examine how metabolic syndrome (MS) prevalence estimates have changed from 1993–1994 to 2008–2009 in a sample of Central/South Americans living in the D.C. area. In this cross-sectional, medical record extraction survey, data from 1993–1994 were compared with data from 2008–2009 on 1,042 male and female adults collected by questionnaire. 28% of our subjects had MS. The most prevalent MS components were low HDL (43.2% men; 50.7% women), elevated triglycerides (37%), and high BMI ≥ 25 kg/m,super,2,/super, (75.6%). Among Central/South Americans, Salvadorans had the highest prevalence of MS (30.7%). MS prevalence was significantly greater for the 2008–2009 subjects (27.9%) compared with 1993–1994 ...

As well as the appearance of Phorusrhacids in Europe in the Middle Eocene, their subsequent disappearance from Europe requires an explanation. Tertiary African ecosystems are not well understood, but those of South America are, and the Phorusrhacids appear to have been the top predators in many South American ecosystems for much of the period. However South America lacked predatory Mammals during this time, the other predators with which Phorusrhacids shared the continent being Marsupials. Placental Mammal predators (Carnivora and later Homo sapiens) reached South America during the Great American Biotic Interchange, which also allowed the Phorusrhacids to briefly colonise North America, an event that was shortly followed by the extinction of both the Phorusrhacids and large Marsupial predators in the Americas (large Marsupial predators also became extinct in Australia shortly after the arrival of Placental predators, in this case Homo sapiens and Canis lupus). In Europe the Phorusrhacids would ...
Bogota, Colombia Colombian President Alvaro Uribe has the swine flu and officials have advised other South American leaders who met with him at a summit of the infection, authorities said Sunday.. The 57-year-old Uribe began feeling symptoms Friday, the same day as a meeting of South American presidents in Bariloche, Argentina, and he was confirmed to have swine flu after returning home, Social Protection Minister Diego Palacio said.. "This isnt something that has us scared," Palacio said at a news conference. Uribe, a key U.S. ally in Latin America, is not considered a high-risk patient and will continue working from his computer, officials said.. Public health director Gilberto Alvarez said in a telephone interview that there was no need to put the president in isolation and that his condition would be monitored for three days to a week.. Palacio said Colombias foreign ministry was informing governments whose leaders may have come in contact with Uribe.. No governments immediately reported ...

Maize (Zea mays ssp. mays), a crop of great importance worldwide, is characterised by its great adaptability and its extraordinary variability both at the molecular and the phenotypic level. Behind these remarkable features lies a complex evolutionary history. The main aim of this research is to contribute to a better understanding of it by answering questions about the origin, phylogenetic relationships, and initial dispersion of maize, using South America as a case study. To achieve this aim, archaeological specimens and primitive landraces were genotyped at 20 microsatellite loci. Sequences of Adh2-UM, a locus informative of the routes of initial dispersion of maize in South America, were also obtained. The data gathered were analysed using tree-building and network methods, and a Bayesian model-based clustering approach to infer population structure. Our results are consistent with a model of initial dispersion by which after its introduction, maize spread along the Andes and through eastern ...
VS is prevalent in northern South America, throughout Central America, and at one site in the United States: Ossabaw Island, Georgia. However, outbreaks of VS have been reported in the western United States, northern Mexico, and temperate regions of South America. The disease can cause blisters on an animals mouth, teats or hooves. Clinical outbreaks of VS in livestock can result in significant economic impact on producers and extensive regulatory responses by governmental agencies, including trade restrictions, market closures, and quarantines. Such measures are needed because of the clinical similarities between VS and foot-and-mouth disease and other foreign vesicular diseases in livestock species. ...
