Microryzomys ( Catalan; Valencian )

provided by wikipedia CA

Microryzomys és un gènere de rosegadors de la família dels cricètids. Les espècies d'aquest grup són oriündes de Sud-amèrica. Tenen el pelatge suau i de color marró. Assoleixen una llargada de cap a gropa de 6–10 cm i una cua de 9–13 cm. Els seus hàbitats naturals són els boscos i herbassars humits situats a altituds d'entre 2.000 i 4.000 msnm. El nom genèric Microryzomys significa 'ratolí d'arrossar petit' en llatí.

Kleinstreisratten ( German )

provided by wikipedia DE

Die Kleinstreisratten (Microryzomys) sind eine in Südamerika lebende Nagetiergattung aus der Gruppe der Neuweltmäuse. Sie umfassen zwei Arten.

Kleinstreisratten sind sehr kleine Vertreter der Neuweltmäuse. Sie erreichen eine Kopfrumpflänge von 6 bis 10 Zentimeter, wozu noch ein 9 bis 13 Zentimeter langer Schwanz kommt. Ihr weiches Fell ist bräunlich gefärbt, die Unterseite ist heller, meist gräulich.

Diese Tieren leben in den Andenregionen von Kolumbien bis Bolivien und Peru. Sie leben in feuchten Wäldern und Grasländern in 2000 bis 4000 Metern Höhe. Sie sind vorwiegend Bodenbewohner und legen Trampelpfade im Gras oder Moos an.

Es gibt zwei Arten:

  • Microryzomys altissimus ist in Kolumbien, Ecuador und Peru beheimatet. Sie kommt bis in 4000 Meter Höhe und ist durch einen kürzeren Schwanz charakterisiert.
  • Microryzomys minutus ist von Venezuela bis Bolivien verbreitet. Sie hat einen längeren Schwanz und dürfte im stärkeren Ausmaß in Wäldern vorkommen und auf Bäumen leben.

Keine der beiden Arten ist laut IUCN gefährdet.

Microryzomys

provided by wikipedia EN

Microryzomys is a genus of rodent in the tribe Oryzomyini of family Cricetidae. It is closely related to Oreoryzomys, Oligoryzomys, and Neacomys.[1] It contains two species, both restricted to the Andes: M. altissimus and M. minutus.[2]

Characteristics

Microryzomys species are small members of the rodent tribe Oryzomyini, weighing in the region of 10 to 15 g (0.35 to 0.53 oz), and characterised by their long soft fur and tail longer than their head-and-body-length. They have small hind feet with six fleshy pads on the under surface, and with the fifth toe nearly as long as the middle three. The four pairs of mammae are arranged in the typical fashion for members of the tribe.[3] At one time, this genus was considered to be a subgenus of Oryzomys, but Carleton and Musser (1989) raised it to full generic status on the basis of various anatomic details of skull and dentition and on certain morphological traits.[4]

Distribution

Microryzomys is found in high mountainous areas of western South America. The range of the genus extends from the Caribbean coastal ranges and the Cordillera de Mérida of Venezuela, through the Cordillera Occidental, Cordillera Central and Cordillera Oriental of Colombia, to the Andes ranges of Ecuador, Peru and Bolivia. This is also the range of M. minutus, because M. altissimus occurs only in the higher parts of this range and is limited to Colombia, Ecuador and Peru. M. minutus mostly occurs in moist forest habitats at altitudes between 1,500 and 3,500 m (4,900 and 11,500 ft), while M. altissimus inhabits moist subalpine forests and páramo grassland, at altitudes between 2,500 and 4,000 m (8,200 and 13,100 ft).[4]

Microryzomys[1] är ett släkte av däggdjur. Microryzomys ingår i familjen hamsterartade gnagare.[1]

Taxonomi

Kladogram enligt Catalogue of Life[1] och Wilson & Reeder (2005)[2]:

Microryzomys

Microryzomys altissimus



Microryzomys minutus



Beskrivning

Dessa gnagare påminner om små risråttor. De når en kroppslängd (huvud och bål) av 6 till 10 cm och en svanslängd av 9 till 13 cm. Den mjuka pälsen är på ryggen brunaktig och på buken oftast gråaktig. Microryzomys skiljer sig även i detaljer av skallens och tändernas konstruktion från närbesläktade gnagare.[3]

Arterna lever i Sydamerika i Anderna från Venezuela till Bolivia. De hittas vanligen mellan 2000 och 4000 meter över havet. Habitatet utgörs av fuktiga och torra skogar samt av bergsängar. Individerna klättrar i växtligheten eller letar på marken efter föda. Honor kan föda tre till åtta ungar per kull.[3]

IUCN listar båda arter som livskraftiga (LC).[4]
