Using field data from a semi-arid forest site in Israel, numerical simulations indicated that the 18O full equilibrium depth varied at this site between 4 cm (January) and 8 cm (November), being sensitive mostly to temperature and soil water content.
On the other hand, increasing photosynthesis by irrigating part of the root system of ponderosa pines in a semi-arid forest resulted in a significant increase in the respiration of the rhizosphere (Irvine et al., 2005).
Although Indicator indicator is still commonly seen throughout the savannah and semi-arid forests of sub-Saharan Africa, it is rarely called upon for help anymore, since manufactured sugar has largely supplanted wild honey as a dietary staple.
High variability in soil-moisture conditions is typical for semi-arid forest-steppe ecosystems where precipitation varies greatly over time.
Arid/semi-arid forests exhibited the smallest, while tropical montane cloud forest displayed the largest ME deviations.
Lowered stand density reduces competition for water in these semi-arid forests, where productivity is usually limited by summer drought.
Arid and semi-arid forests and woodlands (hereafter called «dryland forests»), in spite of their ecological and social importance, have received little attention in land change studies.
Sclerophyllous shrublands and ravines (associated with semi-arid forests) are rated higher than savannahs of "espinales" and shrublands with succulent plants (associated with semi-arid grassland with shrubs).
