1. Morphofunctional characteristics of working mules in mountain areas of the Colombian Central Andes
ABSTRACT. The application of morphofunctional measurements allows the selection of suitable animals to perform working activities and ensure that animal maximum capacities are not exceeded. Mules are commonly used by small farmers for agricultural work in mountain areas where the access is extremely difficult. We aimed to estimate the functionality indexes o

2. Geochronological systematics of the Huayna Potosí, Zongo and Taquesi plutons, Cordillera Real of Bolivia, by the K/Ar, Rb/Sr and U/Pb methods
Abstract The Huayna Potosi, Zongo and Taquesi are Triassic plutons located at the core of the Real Cordillera of Bolivia. In this paper, several Rb-Sr and K-Ar ages obtained in the past at the São Paulo Geochronology Laboratory, yet unpublished, will be presented, along with newer U-Pb Sensitive High-Resolution Ion Microprobe (SHRIMP) determinations made in

3. Areas of endemism of hummingbirds (Aves: Apodiformes: Trochilidae) in the Andean and Neotropical regions
ABSTRACT Using track analysis and cladistic biogeography, we identified areas of endemism of hummingbirds in the Andean and Neotropical regions. Our results point out that the current areas of endemism of hummingbirds occur in the Andes, Guiana Shield, the Lesser Antilles, western Central and North America and the Chiapas Highlands. The cladistic biogeograph

4. Palm species richness, latitudinal gradients, sampling effort, and deforestation in the Amazon region
ABSTRACT Palms are most diverse in warm and humid regions near the equator. Though palms remain relatively well conserved, they are under increasing pressure from deforestation. Here, we analyze patterns of palm species richness relative to latitudinal gradient, sampling effort, and deforestation in the Amazon, and compare patterns of richness and floristic

5. ANUROS DEL NORTE DE LOS ANDES: PATRONES DE RIQUEZA DE ESPECIES Y ESTADO DE CONSERVACIÓN
ABSTRACT Knowledge of Andean anurans is constantly increasing; for this reason, it needs an update. We reviewed scientific literature and museum records to determine the species richness of anurans in the northern Andes and their conservation status based on the IUCN categories. The northern Andes harbor 740 species of anurans, belonging to 13 families and 6

6. Efeitos de mudanças eustáticas e tectônicas na reversão do sistema de drenagem do Rio Amazonas transcontinental
RESUMO: O desenvolvimento do Sistema de drenagem do Rio Amazonas envolveu eventos geológicos nos Andes; arcos de Vaupés, Purus e Gurupá; bacias sedimentares da região, assim como mudanças do nível do mar. A origem e a idade deste rio têm sido discutidas por décadas, e muitas ideias têm sido propostas, incluindo aquelas relacionadas a ele ter se orig

8. The genus Bostryx in central western Argentina: anatomical and distributional description of four of its southernmost species (Gastropoda, Bulimulidae)
ABSTRACT The genus Bostryx Troschel, 1847 is endemic to South America, extending from Ecuador to Chile and Argentina. The southernmost Argentinian species of the genus that inhabit San Luis, San Juan and Mendoza provinces, specially the pre-Andes, Andes and Sierras Pampeanas mountain ranges, were examined. This is the first time the anatomy of Bostryx pastor

9. A molecular contribution to the controversial taxonomical status of some freshwater snails (Caenogastropoda: Rissooidea, Cochliopidae) from the Central Andes desert to Patagonia
For over 40 years malacologists have been discussing the taxonomical status of Heleobia species, an enigmatic genus from Cochliopidae family (Caenogastropoda: Rissooidea). As with other rissooidean families, the considerable character convergence and the paucity of anatomical synapomorphies has proved to be a problem in resolving cochliopid phylogenetic rela

10. Review of Thompsoniella Guimarães with description of a new species from Colombia (Diptera, Calliphoridae, Mesembrinellinae)
Review of Thompsoniella Guimarães with description of a new species from Colombia (Diptera, Calliphoridae, Mesembrinellinae). The Mesembrinellinae (Diptera, Calliphoridae) are exclusively Neotropical with nine genera comprising 36 recognized species, including the genus Thompsoniella Guimarães with a single species, T. anomala Guimarães. We describe a new

11. Una especie nueva de rana arbórea del género Hyloscirtus (Amphibia: Anura: Hylidae) de la Cordillera del Cóndor
Ecuadorian frogs of genus Hyloscirtus comprises 16 described species, of which eleven belong to the H. larinopygion group. They are restricted to the flanks of the Andes, both east and west. An assessment of the herpetofauna in the southern part of Cordillera del Condor (montane forests on sandstone plateaus) province of Zamora Chinchipe, Ecuador, led to the

12. Comunidad y desarrollo en los Andes Peruanos: una crítica etnográfica al programa de modernidad/colonialidad
In the last decades the deconstruction of development, also known as 'postdevelopmentalism', has grown in popularity within social sciences. In Latin America, the theoretical program called Modernity/Coloniality/Decoloniality (MCD) aims at decolonizing the modern thought by re-writing global history from the perspective of local histories.
