The assertion that plants at lower latitudes should be better defended against enemies has a long historical basis but is still controversial. In the current study,

Mutualistic relationships between different species are common in all ecosystems however double mutualisms, where two interacting species benefit each other for two different functions, e.g.

Heteroblastic species show an abrupt change in morphology at a fixed ontogenetic stage, and are relatively frequent in Mediterranean type ecosystems with regular fires. Using the

Plants take up and assimilate nitrogen (N) in the form of nitrate (NO3–) or ammonium (NH4+), or a combination of both. When oxygen availability is reduced

Herbivory-induced defensive responses in plants can be direct (e.g. secondary chemicals to suppress herbivory) or indirect (e.g. extrafloral nectar attracting ants). These different

Most bladderworts (genera Pinguicula, Genlisea, Utricularia, Lentibulariaceae) are pollinated by insects. Bird pollination is rare and has probably evolved independently three times in this family. In

Enantiostyly, a reproductive system characterized by heteromorphic flowers with either left or right style deflection, compels reciprocal pollen transfer between floral types. The potential outcrossing advantage
