“…For this reason it is recommended to conduct further studies by planting this species in mixed stands in order to obtain, additionally to the product of fast growing species, a higher quality product. Our results are in agreement with previous studies that reported UC seedling survival rate to be 19 % higher than OS (Dengler 1992;Mayer 1992;von Schmeling 1994).…”

“…Statistical differences among species and treatments and the interaction among factors are discussed in the text vigorous than those that were not protected. This coincides with autecology descriptions in previous studies that mentioned that this species has ''shade tolerant'' behavior (Dengler 1992;Mayer 1992;von Schmeling 1994). Since it is a slow-growing species, its wood is one of the most valuable on the market.…”

“…Previous plantations assays with S. torminalis indicate that it adapts well to sites with 500 mm rainfall per year and can tolerate up to two months of summer drought (Dengler 1992, Mayer 1992Montero et al 2003). In Patagonia, it can survive under 400 mm rainfall per year condition, but is not suited to drought because the apical bud dies (Godoy et al 2007).…”

“…In juvenile stages, it can survive several years under field conditions, but to grow in height it needs plentiful light conditions (Dengler 1992). Low levels of precipitation plus lighting restrictions may play a major role in the establishment of this species.…”

Evaluation of plantation and early development of five alternatives to ponderosa pine in silvopastoral systems in northwest Patagonia, Argentina

et al. 2016

Previous studies of afforestation in Patagonia indicate that 30-50 % tree cover produces positive effects on the pasture. This coverage level is achieved by applying pruning and strong thinning to reduce the volume of timber production per area unit. From an economic standpoint, in order to not reduce the income level of the system, it is necessary to find tree species that could replace ponderosa pine (Pinus ponderosa) and maximize income per volume unit of wood. We evaluated the feasibility of implementation of five broadleaved tree species (native and exotic) with higher intrinsic wood quality than ponderosa pine. We tested the influence of tree cover generated by a framework of silvopastoral plantation on the increase in survival, regrowth and absolute increase in height, and compared ecophysiological variables (net photosynthetic activity, stomatal conductance, intrinsic water use efficiency) of different species to the status of a traditional plantation without tree cover. Additionally values of air temperature and relative humidity were registered under both cover conditions. Preliminary results support the conclusion that three of these five species could be considered as alternatives to ponderosa pine species for establishing silvopastoral systems with higher timber value. Our Based on the results, the use of tree cover generated under the current plantations of P. ponderosa could increase the success of the establishment of these species.

“…He discusses this referring to a definition of forest by Dengler (1935) and argues that by branching in their upper parts these cacti may also develop kind of a canopy, although walking around in such ''forests'' I often got the impression that the sensation of being under a canopy is much more determined by Mimosaceae, Capparidaceae and Caesalpiniaceae trees mixing with the columnar cacti (see also Vareschi 1980;Fig. 1a,b).…”

Stem CAM in arborescent succulents

Stem CAM with a peripheral chlorenchyma in stem succulents growing up to arborescent sizes and life forms appears to be a unique evolution as it requires delayed and reduced bark formation and stem stomata. However, stem succulence as a convergent morphotype and with it the stem CAM physiotype evolved polyphyletically in many divergent taxa of the dicotyledonous angiosperms. Controlling water budgets is the main ecophysiological benefit of stem succulence and CAM, where the cooperation of a peripheral photosysnthetically active chlorenchyma and a central water storing hydrenchyma is co-ordinately regulated. Thus, a major factor important for performance of stem CAM succulents at the community level is water or drought. Although this implies fitness under osmotic stress, CAM performing stem succulents are not adapted to salinity and are salt stress avoiders where they occur in saline habitats. Notwithstanding the low overall productivity of CAM plants in general, stem CAM plants can show very high productivity under certain circumstances and may also respond to elevated environmental atmospheric CO 2 concentrations with increased growth.
