COMING LATER THIS YEAR: Most people are familiar with hummingbirds and the balletic ways in which they feed on flowers. But did you know that these kinds of relationships first evolved at least 50 million years ago? And that nowadays at least 64 families of birds include species that act as pollinators, for tens of thousands of different plants? N...

Marinas contribute to the degradation of coastal ecosystems, constitute non-indigenous species (NIS) hotspots and function as steppingstones in invasion processes. These often enclose highly modified water bodies that promote the concentration of pollutants and propagules, favoring NIS abundance. In these habitats, floating structures are often the...
