Abstract
This note reports data on occurrence of the echimyid Kannabateomys amblyonyx in Minas Gerais State, southeastern Brazil. Data were obtained from consult to 26 museums, bibliography search and field sampling. We found nine municipalities with species records, eight within the Atlantic Forest biome and one in the transitional area between the Atlantic Forest and Cerrado. Habitats occupied comprised bamboo groves in Montane Stational Semidecidual Forest, Submontane Stational Semidecidual Forest and bamboo patches located in middle of open area, originally covered by Submontane Stational Semidecidual Forest. Potential impacts detected were deforestation, fires, hunting and the presence of livestock and domestic dogs. Key words: bamboo rat, Atlantic Forest, threats, records.
Highlights
Kannabateomys amblyonyx is a large echimyid rodent, distributed from southeastern Brazil to southeastern Paraguay and northern Argentina
We identified nine municipalities with K. amblyonyx records in Minas Gerais State, eight of them in Atlantic Forest domains and one in a transitional area between Atlantic Forest and Cerrado biomes, according to IBGE (2009) (Figure 1)
On 19 November 2010 an individual was photographed by FAS in an area which belongs to Barra do Braúna Power Plant (21o23’39”S, 42o31’01”W; 167m a.s.l.), municipality of Laranjal, Atlantic Forest (IBGE, 2009)
Summary
Kannabateomys amblyonyx is a large echimyid rodent, distributed from southeastern Brazil to southeastern Paraguay and northern Argentina. It inhabits coastal Atlantic Forest, inland rainforests and wet gallery forests, mainly in waterside bamboo groves (Emmons and Feer, 1997). It has nocturnal and arboreal habits, lives in small family groups and defends a territory through vocalization. Consistent information is lacking on the localities and habitats of occurrence of this species, which distribution in Minas Gerais State is poorly known. Aiming to contribute to the knowledge on the distribution and conservation of K. amblyonyx, we present new occurrence sites and summarize the available data on the species distribution, potential threats and habitat occupancy in Minas Gerais
