Flowering plant species and their nectar‐feeding vertebrates exemplify some of the most remarkable biotic interactions in the Neotropics. In the Brazilian Atlantic Forest, several species of birds (especially hummingbirds), bats, and non‐flying mammals, as well as one lizard feed on nectar, often act as pollinators and contribute to seed output of flowering plants. We present a dataset containing information on flowering plant...

Mountaintop removal coal mining is the predominant form of surface mining in the Appalachian Region of the United States and leads to elevated levels of chemical constituents in streams draining mined watersheds. This data set contains measurements of water chemistry in the mountaintop mined landscape of Central Appalachia. These data were collected to determine the accumulation and transport of mercury (Hg) and selenium (Se)...

Aim Species interaction networks are known to vary in structure over large spatial scales. We investigated the hypothesis that environmental factors affect interaction network structure by influencing the functional diversity of ecological communities. Notably, we expect more functionally diverse communities to form interaction networks with a higher degree of niche partitioning. Location: Americas. Time period: Current. Major...

Morphological, ultrastructural, and cytochemical characteristics of the red alga Plocamium cartilagineum from Antarctica have been studied and compared with those of the same species from the Mediterranean Sea. Distinct regions with possibly different functions were recognisable in the bushy thallus of Plocamium cartilagineum. Chloroplasts were concentrated in the outermost cell layer, while in the other cortex cells abundant...
