Gold mining (GM) is a major source of metals and metalloids in rivers, causing severe environmental pollution and increasing the exposure risks to the residents of surrounding areas. Mining in Ecuadorian Amazonia has ...

The aim of this paper is to analyze energy pathways for a fossil fuel rich developing country towards an energy transition considering national and international oil availability using Ecuador as a reference. An integrated ...

Aim: To investigate the geographic patterns and ecological correlates in the geo-graphic distribution of the most common tree dispersal modes in Amazonia (endozoo-chory, synzoochory, anemochory and hydrochory). We examined ...

Wastewater treatment has become a momentous field today. Membrane ultrafiltration processes are booming due to their versatility of use. However, there are limited studies related to the technology of automatic data ...

Stingless bees are effective pollinators of native tropical flora. Their environmental service maintains flow of pollen through pollination, increase reproductive success and influence genetic structure in plants. The ...

Oleanolic acid is a pentacyclic triterpenoid found in numerous plant species and is a precursor to several bioactive triterpenoids with commercial potential. However, oleanolic acid accumulates at low levels in plants, and ...

The mortiño (Vaccinium oribundum) is characterized by its high content of polyphenols and anthocyanins, as well as high antioxidant activity. This research analyzed the effect of drying (convection drying and lyophilization) ...

Globally, pesticides are toxic substances with wide applications. However, the widespread use of pesticides has received increasing attention from regulatory agencies due to their various acute and chronic effects on ...

Repeated evolution can provide insight into the mechanisms that facilitate adaptation to novel or changing environments. Here we study adaptation to altitude in two tropical butterflies, Heliconius erato and H. melpomene, ...

We propose a new computational proof for the division algorithm that, usingvector algebra, generalizes the remainder theorem to divisions for polynomials of any degreeover a generic integral domain. Then, we extend this ...
