Population dynamics of the rat Microryzomys minutus (Rodentia: Muridae) in the Venezuelan Andes.
The population dynamics of the small forest rice rat Microryzomys minutus, a murid rodent that occurs in the high altitudes of the northern and central Andes, was studied in disturbed and primary environments in a cloud forest of the Venezuelan Andes (Juan Pablo Peñaloza National Park, 8 degrees 11'N, 71 degrees 49'W). We collected 121 animals (66 female female and 55 male male) between 1995 an...

متن کاملNew dinosaur (Theropoda, stem-Averostra) from the earliest Jurassic of the La Quinta formation, Venezuelan Andes
Dinosaur skeletal remains are almost unknown from northern South America. One of the few exceptions comes from a small outcrop in the northernmost extension of the Andes, along the western border of Venezuela, where strata of the La Quinta Formation have yielded the ornithischian Laquintasaura venezuelae and other dinosaur remains. Here, we report isolated bones (ischium and tibia) of a small n...
متن کاملHolocene hydrologic balance of tropical South America from oxygen isotopes of lake sediment opal, Venezuelan Andes
Precipitation in the South American Andes is derived from Atlantic Ocean evaporation which is modified by passage over lowland South America. The isotopic composition of Andean precipitation reflects evaporation conditions over the Atlantic Ocean, moisture recycling during advection across the South American lowlands and uplift to the Andes. Records of the oxygen isotope composition of precipit...
متن کاملPalynological signal of the Younger Dryas in the tropical Venezuelan Andes
The occurrence, or not, of the Younger Dryas cold reversal in the tropical Andes remains a controversial topic. This study reports a clear signal for this event in the Venezuelan Andes, employing high-resolution palynological analysis of a well-dated sediment core from Laguna de Los Anteojos, situated around 3900 m elevation, within grass páramo vegetation. The lake is surrounded by some Polyle...
