Climate changes are occurring rapidly at both regional and global scales. Farmers are faced with the challenge of developing new agricultural practices to help them to cope with unpredictable changes in environmental, ...

Temperature and oxygen are recognised as the main drivers of altitudinal limits of species distributions. However, the two factors are linked, and both decrease with altitude, why their effects are difficult to disentangle. This ...

Freshwater biodiversity is under threat across the globe1, with climate change being a significant contributor2,3. One impact of climate change is the rapid shrinking of glaciers4 , resulting in a reduction in glacial ...

Existe evidencia científica que sugiere que las variaciones de un gradiente ecológico moldean algunas características propias de cada organismo como su comportamiento o morfometría. En este estudio, analizamos el efecto ...

We review and analyze the recent development and future challenges facing entomology as a science in Ecuador, a country with limited fi nancial and human resources and numerous environmental problems. Taxonomic studies of ...

The stress-gradient hypothesis (SGH) postulates an increase in the frequency of positive species interactions at increasing amounts of stress. While theSGHhas been extensively tested in plant–plant interactions along ...

Under the ongoing climate change, understanding the mechanisms structuring the spatial distribution of aquatic species in glacial stream networks is of critical importance to predict the response of aquatic biodiversity ...

Los insectos plaga son una de las principales causas de pérdidas en cultivos y en almacenes a nivel mundial. En los Andes tropicales, el complejo de polillas de la papa (CPP) (Lepidoptera: Gelechiidae) está conformado por ...

The downstream pattern in benthic macroinvertebrate assemblages along glacier-fed streams is a result of decreasing glacial influence on environmental conditions. However, meltwater run-off shows temporal variation, reflected ...

A major challenge of ecological research is to assess the functional consequences of species richness loss over time and space in global biodiversity hotspots, where extinctions are happening at an unprecedented rate. To ...
