Actividad ígnea y tectónica en la cordillera Central durante el Meso-Cenozoico

Boletín Geológico, 1969
Durante el Meso-Cenozóico la actividad ígnea y tectónica en la cordillera Central, se desarrolla en dos etapas con caracteres distintivos. La Primera etapa, de edad Jura-Triásico, está asociada al solevantamiento de la cordillera y se manifiesta en ...

Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

The Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Neoproterozoic ultramafic and mafic magmatism in the Eastern Cordillera of the central peruvian Andes: the Tapo Massif [PDF]

, 2010
A highly dismembered assemblage of ultramafic and mafic rocks is exposed in the Eastern Cordillera of the Central Peruvian Andes, extending along a discontinuous NW-SE belt over some 250 km between 12° and 9° S of latitude.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

A glacial geochronology of Cordillera Pariacaca, central Peru

Quaternary Science Reviews
Glacial dynamics in the Outer Tropics reflects a complex interplay of variations in precipitation and temperature driven by large scale ocean-atmospheric dynamics. Cosmogenic dating of moraines, palaeoglacier reconstruction and comparison to climate proxies adds to our understanding of palaeoglacier dynamics in relation to these forcings and can help ...

Modeling climate adaptive habitat connectivity for conservation planning in Colombia

Ecography, EarlyView.
To remain effective under global change, conservation decisions must anticipate shifting climates, species responses to climate change and the dispersal pathways needed to track suitable climate. Yet most assessments of ecological connectivity do not consider how the landscape will change, or, if they do, they only consider a single future time point ...

Modeling the impacts of grazing management on livestock behavior and performance: A case study in the Peruvian Andes

Grassland Research, EarlyView.
Our modeling study shows that livestock management strongly influences grazing behavior and animal performance in the Peruvian Andes. Furthermore, adjusting stocking rates and improving animal distribution can enhance forage intake and body condition while increasing forage biomass.

Bauhinia naniflora: a new species of section Amaria (Cercidoideae: Leguminosae) from Colombia

Nordic Journal of Botany, EarlyView.
Bauhinia, the most species‐rich genus of Cercidoideae (Leguminosae), is pantropically distributed and includes four sections in the Americas. During an ongoing taxonomic revision of American Cercidoideae, a new species of Bauhinia sect. Amaria ser. Decandrae currently endemic to Colombia was identified and is here described as Bauhinia naniflorasp nov.
