Floral biology of tropical alpine plants
Holzbachová, Lucie ; Sklenář, Petr (advisor) ; Ptáček, Jan (referee)
Tropical alpine environments are characterised by specific environmental conditions to which the local plants adapted through evolution. The specificity is especially in a strong diurnal climate with temperatures falling below zero at nights. At the same time, this environment lacks thermal seasonality, which allows growth and flowering throughout the year. While floral biology is relatively well described in temperate regions, it has only been studied sporadically in the tropics. This study summarises the knowledge of floral biology in tropical alpine environments with a focus on zoophily plants. The principal part of this work is dedicated to floral traits, focusing on flowering phenology, which is diversified for every species during the year. In this way, plants face competition, especially for their pollinators, which decrease in abundance with altitude. Although not all phenological strategies have been studied so far, we can find several main flowering schemes. This literature review points to unexplored research topics about floral biology of plant inhabiting tropical mountains that might provide a basis for future studies.
