Ocean sprawl is the proliferation of human-made structures on the seafloor. These structures include everything from seawalls to discarded garden statues. Many of the structures that lead to ocean sprawl … Continue readingWhat is ocean sprawl?
Foundation species, or ecosystem engineers, are organisms that physically modify the environment in ways that benefit other species and enhance diversity. For instance, reef-building corals and canopy-forming kelps form structurally … Continue readingWhat are foundation species?
Synanthropes often share several characteristics: They are typically generalists –their diet varies according to what’s available. They are often opportunistic, “r-selected” species (short lifespan with high reproduction rate – think … Continue readingWhat makes an urban synanthrope?
