Skuë` (from the bribri, mouse) was born as an urgency to preserve our small mammals, mice and shrews, highly threatened by lack of information and false popular beliefs. Of the 107 species of non-flying terrestrial mammals of Costa Rica, half correspond to small mammals, and in these we find most of our endemic mammals with 23 species (82%). Even so, these species are subject to discredit on the part of society in general, often because of the introduced species, associating them with endless discomforts to health and human economy. However, in this group of small organisms we find large servers of our ecosystems, providing high-importance services such as seed dispersal, pollination, biological controllers of some insect populations, and they are also the basis of the food chain of many mammals. size. Conservation efforts are usually directed towards larger species, since many may be more attractive to the general population and, in presenting large areas of home, they protect other smaller species, despite this benefit. Small species are relegated to a secondary role and go unnoticed by the population. Skuë` aims to generate truthful information, with scientific methods, that help to better understand and give it the place that our endemic fauna deserves. Through ecological studies of high grade and information about the state of health of these populations it is desired to inform and educate the Costa Rican population about these issues, to make known our own unique fauna in the world, and that society adopts it. as such, getting rid of bad prejudices and false beliefs about these species.
