Improving Water Management Education across the Latin America and Caribbean Region
Education can help secure inclusive and resilient development around water resources. However, it is difficult to provide the latest science to those managing water resources (both now and in the future). Collectively, we hypothesize that dissemination and promotion of scientific knowledge using students as central...

Validation of Satellite Estimates (Tropical Rainfall Measuring Mission, TRMM) for Rainfall Variability over the Pacific Slope and Coast of Ecuador
A dense rain-gauge network within continental Ecuador was used to evaluate the quality of various products of rainfall data over the Pacific slope and coast of Ecuador (EPSC). A cokriging interpolation method is applied to the rain-gauge data yielding a gridded product at 5-km resolution covering the period...

Use of the surf zone of sandy beaches by croaker’s larvae (Cynoscion spp.), Province of Guayas, Ecuador
The surf zone of sandy beaches exhibits high faunal diversity and can be a nursery habitat for fish and crustacean. Croakers (Cynoscion spp.) are commercially and ecologically important euryhaline fishes whose larvae are found in the surf zone of sandy beaches; however, little is known about their biology. In this project

Analysing the effects of water quality on the occurrence of freshwater macroinvertebrate taxa among tropical river basins from different continents
Macroinvertebrates are globally used in environmental monitoring and assessment. However, due to environmental and biological evolution, local adaptations of species might occur. This can contribute to uncertainties in the extrapolation of family-specific ecological models developed from...

Generalized Linear Models to Identify Key Hydromorphological and Chemical Variables Determining the Occurrence of Macroinvertebrates in the Guayas River Basin (Ecuador)
The biotic integrity of the Guayas River basin in Ecuador is at environmental risk due to extensive anthropogenic activities. We investigated the potential impacts of hydromorphological and chemical variables on biotic integrity using macroinvertebrate-based bioassessments. The bioassessment methods utilized included...

Spatio-temporal variability of the surf-zone fauna of two Ecuadorian sandy beaches
Temperate and subtropical sandy beach surf zones present diverse and abundant fauna that are important in local food webs. However, dynamics of these fauna have been poorly studied in tropical areas. The aims of the present study were to describe the small swimming surf-zone fauna (~1–5 mm in length) of two Ecuadorian sandy beaches...
