“…(1) as a function of the availability of photosynthetically active radiation (GJ ha −1 year −1 ), the proportion of radiation that was absorbed (a fraction), and light-use efficiency (Mg biomass per GJ of absorbed radiation). Equation (1) has been used previously to examine the interactions in mixed-species stands in relation to nutrients [16], water [17][18][19][20], and light [21,22]. Many processes can influence diversity-productivity relationships in forests (Table 1).…”

Through complementarity interactions, mixedspecies forests can be more productive than monocultures, and this effect can increase with tree-species richness. However, this is not always the case. This review examines the processes and stand structural attributes that can influence diversity-productivity relationships (DPRs); how they influence resource availability, resource uptake, and resource-use efficiency; and also describes some important differences between tree-diversity versus grassland-diversity experiments. The size of the complementarity effects caused by these processes and stand structures varies along spatial and temporal gradients in resource availability and climate. These spatial and temporal dynamics have now been examined in many studies, and the general patterns are summarized using a simple framework; complementarity is predicted to increase as the availability of resource BX^declines (or climatic condition X becomes harsher) if the species interactions improve the availability, uptake, or use efficiency of resource X (or interactions improve climatic condition X). Importantly, this framework differs from the stress-gradient hypothesis to account for a wider range of inter-specific plant interactions (not only facilitation) by considering contrasting methods used to quantify species interactions while accounting for stand structure. In addition, complementarity (as opposed to facilitation) for a given species combination can increase as growing conditions improve in forests, contrary to predictions of the stressgradient hypothesis with regards to facilitation. This review indicates that while the effects of tree-species diversity on growth and other forest functions are now receiving a lot of attention, far less is known about the effects of structural diversity on growth or forest functioning. Direct measurements of the processes, as opposed to focusing mainly on growth responses, could greatly contribute to our understanding of structural diversity effects.

“…Recent studies suggest positive mixture effects on many ecosystem functions such as lower tree mortality, enhanced biomass productivity coupled with higher resource-use efficiency (including nutrients, water and light) by trees, higher decomposition rates and better nutrient retention [10][11][12][13][14][15][16]. In general, it is assumed that these responses of ecosystem processes are due to changes in species or functional-group diversity that might result from a combination of two different mechanisms [17].…”

“…This was mostly due to increased productivity of the nitrogen-fixing species in the mixed stands. The negative side of this higher productivity might be that it could be accompanied with higher water consumption making those plantations more susceptible to drought if water resources get depleted earlier or more extensively [14,22,24,25]. Nevertheless, in a study from Panama, trees planted in mixtures were able to maintain higher transpiration rates during the dry season [26] due to complementary soil water use between different species [27].…”

Tropical tree plantations usually consist of a single exotic fast growing species, but recent research describes positive effects on ecosystem functions from mixed tropical tree plantations. In this review, we present the current knowledge of drought resistance of tropical mixed species plantations and summarize preliminary evidence from a tree biodiversity experiment in Panama. Converting mono-specific stands into mixed ones may improve stand stability and might reduce increasing abiotic and biotic disturbances due to climate change. However, little is known about the extent to which tropical tree species or tropical tree communities can resist increasing disturbances in the short term, e.g., water limitations due to increasing dry season intensity or length, or about their resilience after such disturbances and their capacity to adapt to changing conditions in the long term. Studies relating drought resistance and resilience to community diversity are missing. Further, we highlight the urgent need for a multifactorial manipulative throughfall reduction experiment in tropical environments. The outcome of such studies would greatly assist the forestry sector in tropical regions to maintain highly productive and ecologically sound forest plantations in a changing climate.

“…Hellriegel (1883) and Maximow (1923) are considered to be among the fi rst who carried out calculations on the relationship between increase in dry matter and water requirement. By dividing the biomass productivity, expressed as organic dry matter, with the water lost by transpiration or whole evapotranspiration, wateruse effi ciency of productivity (WUE P ) or long term WUE (WUE L ) is obtained (de Wit, 1958;Lindroth et al, 1994;Cienciala and Lindroth, 1995;Linderson et al, 2007;Forrester et al, 2010). Sometimes the reciprocal transpiration, evapotranspiration or assimilation ratio is used describing the water use per unit of growth (Jones and Mansfi eld, 1972;Masle et al, 1992).…”

FISCHER, M., TRNKA, M., KUČERA, J., FAJMAN, M., ŽALUD Z.: Biomass productivity and water use relation in short rotation poplar coppice (Populus nigra x P. maximowiczii) in the conditions of Czech MoravianHighlands. Acta univ. agric. et silvic. Mendel. Brun., 2011, LIX, No. 6, pp. 141-152 The plantations of short rotation coppice (SRC) usually based on poplar or willow species are promising source of biomass for energy use. To contribute to decision-making process where to establish the plantations we evaluated the water consumption and its relation to biomass yields of poplar hybrid clone J-105 (Populus nigra x P. maximowiczii) in representative conditions for Czech-Moravian Highlands. Water availability is usually considered as one of the main constraints of profi table SRC culture and therefore we focused on analyzing of the linkage between the aboveground biomass increments and the total stand actual evapotranspiration (ET a ) and on water use effi ciency of production (WUE P ). During the seasons 2008 and 2009 the total stand ET a measured by Bowen ratio energy balance system constructed above poplar canopy and the stem diameter increments of randomly chosen sample trees were examined. The stem diameters were subsequently converted to total aboveground biomass (AB) by allometric equation obtained by destructive analysis at the beginning of 2010. The biomass volume and its increment of particular trees were subsequently converted to the whole canopy growth and correlated with the ET a values. Our results revealed that there was a statistically signifi cant relation between water lost and biomass growth with coeffi cients of determination r 2 0.96 and 0.51 in 2008 and 2009 respectively. By using multiple linear regression analysis additionally accounting for eff ect of precipitation events and thermal time (sums of eff ective temperatures above +5 °C) the AB growth was explained from 98 and 87% in 2008 and 2009, respectively. Therefore for further analysis the multiple linear regression model was applied. The dynamic of seasonal WUE P (expressed as gram of AB dry matter per thousand grams of water) reached up to 6.2 and 6.8 g kg −1 with means 3.13 and 3.54 g kg −1 in both executed years respectively. These values are situated in higher range comparing to the other broadleaved tree species of temperate climate zone and suggest that economically profi table plantation (defi ned by yield at least in the range of 10-12 Mg ha −1 year −1 of dry matter content) will consume more than 450-500 mm per growing season and thus will demand a locality with higher and adequately temporally distributed amount of precipitation especially in rain fed areas such as the discussed Czech-Moravian Highlands.short rotation coppice, biomass increment, water consumption, water use effi ciencyThe term short rotation coppice (SRC) is generally used for any high-yielding woody species managed in a coppice system usually grown especially for energy use on arable land. Typically, these crops are harvested on a 3-7 years long ro...
