“…Capybara (Hydrochoerus hydrochaeris): the capybara is the largest living rodent, with adults weighing 49 -50 kg (range 35 -65) [29]. This large mammal has long been reported to inhabit the grasslands of Marajó Island [10] [30] [31].…”

Large- and Medium-Sized Land Mammals of Northeast Marajó Island, Lower Amazon, Brazil

Marajó, located in the lower Amazon, Brazil, is one of the largest river islands in the world. Most of the island is subject to tidal or seasonal flooding. Despite its historical, cultural and geographical importance, Marajó Island remains relatively less investigated in terms of mammal diversity, ecology and community structure than the rest of the Amazon. This scenario has motivated the presentation of this list of land mammals of eastern Marajó Island. Two field surveys were conducted in the course of 7-11 December 2012 and 17-25 October 2013 in Jaranduba, Dunas and Ribanceira Farms, northeast portions of Marajó Island. A total of 23 large and medium-sized land mammal species were recorded in the study area. These farms host a representative mammal community of northeastern Marajó, an area lacking previous faunal studies. Human pressure over centuries has deeply modified the environment in Marajó. Therefore, striking evidence of a long human-populated past in this island is in accordance to many other sites throughout the Amazon plain. The result of a land mammal survey in northeastern Marajó is a clear evidence of past and present human interference in the island. Even though Marajó Island has exalted mammal diversity, it will be much higher if long-term studies are effectively implemented. KeywordsMammals, Checklist, Lower Amazon, Marajó Island S.

“…Additionally, in endemic areas for BSF in the state of São Paulo, population densities of capybaras have reached numbers up to 40 times higher than those recorded in natural environments such as the Amazon and Pantanal [ 18 ]. In this region, the constant availability of water resources ( S1 Fig ), is essential for establishment of capybara populations, since this is a semiaquatic vertebrate species that depends on water source for thermic regulation, reproduction (capybaras mate only in water), and predator protection [ 19 ]. On the other hand, the increase of capybara populations in these areas should depend primarily on availability of food sources, as typically known for rodents such as capybaras [ 19 ].…”

Sugar cane is well known as one of the most appreciated food by capybaras, and the economic impact of capybara on damage to sugarcane crops is a reality in the state of São Paulo [ 20 ].…”

Satellite Hyperspectral Imagery to Support Tick-Borne Infectious Diseases Surveillance

2015

This study proposed the use of satellite hyperspectral imagery to support tick-borne infectious diseases surveillance based on monitoring the variation in amplifier hosts food sources. To verify this strategy, we used the data of the human rickettsiosis occurrences in southeastern Brazil, region in which the emergence of this disease is associated with the rising capybara population. Spatio-temporal analysis based on Monte Carlo simulations was used to identify risk areas of human rickettsiosis and hyperspectral moderate-resolution imagery was used to identify the increment and expansion of sugarcane crops, main food source of capybaras. In general, a pixel abundance associated with increment of sugarcane crops was detected in risk areas of human rickettsiosis. Thus, the hypothesis that there is a spatio-temporal relationship between the occurrence of human rickettsiosis and the sugarcane crops increment was verified. Therefore, due to the difficulty of monitoring locally the distribution of infectious agents, vectors and animal host’s, satellite hyperspectral imagery can be used as a complementary tool for the surveillance of tick-borne infectious diseases and potentially of other vector-borne diseases.

“…Según Moreira et al (2013) los carpinchos actuales, género Hydrochoerus Brisson, 1762, están representados por dos especies con distintas distribuciones geográfi cas, H. isthmius Goodman, 1912y H. hydrochaeris Linnaeus, 1766. La primera especie mencionada está distribuida hacia el oeste de los Andes, en Panamá, Colombia y Venezuela (Moreira et al, 2013) mientras que la segunda, de mayor tamaño corporal, habita hacia el este en Venezuela, Colombia, Ecuador, Perú y Bolivia, también habita en Guyana, Surinam, Guayana Francesa, Brasil, Paraguay, Uruguay y noreste de Argentina extendiéndose hacia el sur en la Provincia de Buenos Aires (Mones & Ojasti, 1986;Moreira et al, 2013).…”

-BODY MASS ESTIMATION OF A QUATERNARY SPECIMEN OF THE EXTINCT CAPYBARANEOCHOERUS THROUGH CRANIODENTAL MEASUREMENTS. An estimated body mass of a specimen of Neochoerus Hay cf. N. aesopi (Leidy) (Mammalia, Rodentia, Hydrochoeridae) from the Quaternary of Uruguay was made based on craniodental measurements. Regression equations used to estimate the mass of other fossil rodents were applied. A value reference was also calculated by scaling of a specimen of the extant Hydrochoerus hydrochaeris (Linnaeus). In this study it is estimated that this extinct rodent may have reached a three times bigger mass than an extant capybara.Key words: Neochoerus, capybara, rodent, body mass, regression.RESUMO -Com base em medidas crânio-dentárias foi realizada uma estimativa da massa corporal de um espécime de Neochoerus Hay cf. N. aesopi (Leidy) (Mammalia, Rodentia, Hydrochoeridae) do Quaternário do Uruguai. Foram aplicadas equações de regressão que têm sido empregadas para a estimativa de massa de outros roedores fósseis. Além disso, foi calculado um valor de referência pelo escalonamento de um espécime atual de Hydrochoerus hydrochaeris (Linnaeus). No presente estudo se estima que este roedor extinto possa ter alcançado uma massa corporal três vezes maior do que a da capivara atual.
