Organismic Interactions and Plant Water Relations

  • Rainer Lösch
  • Dirk Gansert
Part of the Progress in Botany book series (BOTANY, volume 63)


Plants normally function as physiological units that respond to ambient conditions regulating their water relations, mostly independent of other organisms that co-occur in the same habitat. However, water consumption from the soil and vapor transpiration into the atmosphere can influence local pedospheric and atmospheric conditions in a rather specific manner. Feedback can occur in this way, from a plant community as part of the biotic component of an ecosystem, to the abiotic parameters of the habitat. Competition for soil water reserves results from these interactions, and the canopy microclimate that influences transpiration rates can deviate drastically from the conditions that would control latent heat exchange of a solitary plant under the temperature and humidity conditions of the mixed layer of the atmosphere. Moreover, quite often plant water relations are influenced directly by other organisms that interact with a plant individual in mutualistic, parasitic or symbiotic ways. Other plant individuals, fungi and microorganisms as well as animals are such interacting partners.
