This article presents an overview of glaciation studies in the northern tropical Andes (Venezuela, Colombia and Ecuador) mostly based on glacial geochronological data. The oldest dated evidences of glaciations are recorded in the Colombian Andes at the Bo... see more

The last deglaciation is an interval of marked changes in the climate system. The records of glaciation of tropical mountains offer unique opportunities to assess the timing of changes and the sensitivity of tropical climates to global and regional atmosp... see more

The tropical Andes of Peru and Bolivia are important for preserving geomorphic evidence of multiple glaciations, allowing for refinements of chronology to aid in understanding climate dynamics at a key location between hemispheres. This review focuses on ... see more

A reconstruction of the continental climate of southern South America, based on physiognomic analyses of fifteen taphofloras, coming mainly from Chile and Argentina, is presented here. Based on the climate estimates and the phytogeographical composition o... see more

The aim of this study is to constrain the timing of the deglaciation process since the Last Local Glacial Maximum in HualcaHualca volcano and Patapampa Altiplano, located in the Andean Central Volcanic Zone. Nine 36Cl cosmogenic surface exposure dating of... see more

We report the presence of the bobcat (Lynx rufus) in the northeastern of the state of Hidalgo, in the municipality of San Felipe Orizatlán, at 156 meters of altitude. One individual male of L. rufus was run over in a dirty road and donated by local people... see more

La deforestación es una de las mayores amenazas para la vida del hombre, ya que los bosques ayudan a mantener el equilibrio ecológico y la biodiversidad, es por ello que muchos científicos hoy día se han dado a la tarea de tratar de dar solución a este pr... see more

Microalgae are photosynthetic microorganisms that contain carbohydrates can be converted into glucose through a hydrolysis process so that they can be used as raw materials for bioethanol production. Navicula sp. strain TAD is a type of marine m... see more

Climbers influence the diversity and composition of forest ecosystem immensely. We have investigated the floristic composition of climbing plants in tropical forests of Similipal Biosphere Reserve (SBR), Odisha, India. A total of 120 climber plant species... see more
