TL;DR: Investigating phosphorus availability and associated processes in the rhizosphere of perennial ryegrass and radiata pine confirmed that microbial and enzyme activities played an important role in the mineralization of soil organic P, particularly under radita pine.
Abstract: A short-term glasshouse experiment was carried out with two grassland soils to investigate phosphorus (P) availability and associated processes in the rhizosphere of perennial ryegrass (Lolium perenne L.) and radiata pine (Pinus radiata D. Don.) using a thin slicing technique. Results showed that readily extracted forms of soil inorganic P were depleted by both ryegrass and radiata pine, although depletion zones extended further adjacent to radiata pine (5 mm) compared with ryegrass (3 mm). Accumulation of bicarbonate extractable organic P occurred in rhizosphere soil under both ryegrass and radiata pine, which was related to increased levels of microbial biomass. Enhanced depletion of sodium hydroxide extractable organic P apparent in the rhizosphere of radiata pine compared with ryegrass was related to the presence of greater concentrations of water-soluble organic C, microbial biomass and higher alkaline phosphatase and phosphodiesterase enzyme activities. These results confirmed that microbial and enzyme activities played an important role in the mineralization of soil organic P, particularly under radita pine.

TL;DR: In this article, a balanced experiment based on 20 field plots located in a 21 km 2 Scots pine forest in southeast Norway covering age classes from newly regenerated to old forest, leaf area index (LAI) was determined in field by a LAI-2000 instrument and hemispheric photography.

TL;DR: This long-intervalled flowering and fruiting phenology which dominates these lowland dipterocarp forests may have partly contributed to the lowered animal biomass frequently alluded to when these forests are compared with neotropical forests.
Abstract: The general flowering of lowland dipterocarp forests of South-east Asia is a unique phenomenon that occurs intermittently, sometimes many years apart, and may be widespread throughout the region or sporadic. During a general flowering a very large number of tree families, including the well-known Dipterocarpaceae, flower and fruit exceptionally heavily. The huge pulse of flowering is echoed by an apparent explosion in the number of pollinators, and this is further augmented by migration of pollinators from the forest fringes. The huge demand for pollinators seems to be solved among several dipterocarps through utilization of tiny, fast breeding, floral-feeding insects such as thrips and hoppers. Competition for pollinators is further reduced through development of sequential flowering among several groups of trees that share similar pollinators. The resulting massive general fruiting seems to contribute to a heightened level of faunal activity and numbers. This long-intervalled flowering and fruiting phenology which dominates these lowland dipterocarp forests may have partly contributed to the lowered animal biomass frequently alluded to when these forests are compared with neotropical forests.

TL;DR: In this article, the state-of-the-art desertification assessments on both the national and local levels are presented along with suggestions for possible solutions to these problems and two major problems facing the assessment of degradation, the uncertainty of baseline assessments and indictor systems and the misuse of remotely sensed data sources.
