“…Several studies have reported that other mesofauna, Mesostigmata and Collembola, respond to both food availability (Bardgett et al 1993;Cole et al 2008) and soil compaction (Koehler 1999;Larsen et al 2004;Cole et al 2008). Across the two soils (Allophanic and Brown) Mesostigmata and Collembola did not show a consistent response to management, which may reflect their shorter life cycles than Oribatida (Cole et al 2008) and their ability to respond faster to changes in environmental conditions.…”

“…2, Table 5). Oribatid mites (a large proportion of the mesofauna community) are particularly sensitive to changes in the soil physical environment caused by stock treading (loss of habitat) and earthworm burrowing (disturbance) as they have hard exoskeletons and long life cycles (Maraun et al 2001;Cole et al 2008). In both soils (Allophanic and Brown), more smaller oribatid mites (i.e.…”

“…Soil-inhabiting earthworms are capable of burrowing and increasing habitable pores (Lee & Foster 1991), benefiting the ecosystem by services influencing water and air movement through the soil. However, mesofauna with body widths of 0.1Á2 mm, such as detritivorous oribatid mites, may be negatively influenced by compaction (Cole et al 2008).…”

Earthworm abundance increased and Oribatida abundance decreased on a Brown soil with increasing inputs of phosphorus (P) fertiliser and sheep stocking rates. To determine if the same response to increasing management intensity is found in Allophanic soil, samples were collected from a long-term sheep-grazed trial with two contrasting management regimes, low and high intensity. As pastures on the Allophanic soil became more productive and were grazed with more sheep, there was a tendency for earthworm abundance to increase and oribatid abundance to decrease. Both these trends were consistent with those on the Brown soil, supporting the potential of earthworms and Oribatida as biological indicators. Oribatid mites, which produce nutrient rich faecal pellets, were positively correlated with porosity. The higher earthworm abundances in more intensive sheep grazed pastures may have a positive influence on ecosystem services such as air and water movement, and organic matter incorporation.

“…That is, dominant species should use the most available forms of soil N and subordinate species less available forms (McKane et al 2002). Different functional groups follow different N use strategies to meet their N demands (Kahmen et al 2006), and different responses by different functional groups in a community may buffer changes in community-level resource acquisition and net primary productivity (Cole et al 2008;Rich et al 2008).…”

Due to their particular physiology and life history traits, bryophytes are critical in regulating biogeochemical cycles and functions in alpine ecosystem. Hence, it is crucial to investigate their nutrient utilization strategies in comparison with vascular plants and understand their responses to the variation of growing season caused by climate change. Firstly, this study testified whether or not bryophytes can absorb nitrogen (N) directly from soil through spiking three chemical forms of 15N stable isotope tracer.Secondly, with stronger ability of carbohydrates assimilation and photosynthesis, it is supposed that N utilization efficiency of vascular plants is significantly higher than that of bryophytes. However, the recovery of soil N by bryophytes can still compete with vascular plants due to their greater phytomass. Thirdly, resource acquisition may be varied from the change of growing season, during which N pulse can be manipulated with 15N tracer addition at different time. Both of bryophytes and vascular plants contain more N in a longer growing season, and prefer inorganic over organic N. Bryophytes assimilate more NH4+ than NO3-and amino acid, which can be indicated from the greater shoot excess 15N of bryophytes. However, vascular plants prefer to absorb NO3-for their developed root systems and vascular tissue. Concerning the uptake of three forms N by bryophytes, there is significant difference between two manipulated lengths of growing season. Furthermore, the capacity of bryophytes to tolerate N-pollution may be lower than currently appreciated, which indicates the effect of climate change on asynchronous variation of soil N pools with plant requirements.

“…Soil nitrogen (N) availability has significant influences on plant growth, and limits net primary productivity (Cole et al, 2008). Nitrogen available for crops, however, has to release from soil organic matter via microbial decomposition process, thus the recommendation for nitrogen fertilizer application rate in cropping system used the content of soil organic matter as the criterion for rough estimate.…”

A laboratory aerobic incubation experiment was conducted to assess the influence of plant residue, soil moisture content, and soil types on mineralization of organic N. The experimental design was a 2 x 3 x 5 factorial arrangement in a Randomized Complete Block design (RCBD) with three replications. The three factors were (1) two levels of plant residue (0 and 4 ton/rai of grinded cassava shoot), (2) three levels of soil moisture (PWP, ½ AWCA, and FC), and (3) Five upland soil series of the Western region of Thailand, consisting of three main soil textures (fine, medium, and coarse texture). Nitrogen mineralized from native and added organic matter was examined at specific time intervals for 1 year. The data was fitted to a logistic mathematical model describing the relation between mineral N versus moisture content (θ), level of plant residue (PR), and time (t). The model was verified by predicting the amount of mineral N released under a given condition and the result was compared to the observed value under the same condition. Application of the model for field condition where soil moisture fluctuates was performed by differentiating the original model to obtain the relation between rate of mineral N production versus N (t), which was the implicit function of θ, PR, and t. Stepwise calculation of the cumulative mineral N with time was developed to predict the amount of N mineralized through time. The results revealed that addition of 4 ton/rai plant residue drastically increased mineral N by 3.6 folds. The effect of soil moisture content and mineralization of organic N confirmed the significance of water on microbial activities. A satisfactory result was obtained from the mathematical model verification. The b and R 2 values were close to 1.0 and the t-test were non-significant. A rather high value of Root Mean Squared Error (RMSE) was obtained contributing to the cycles of microbial population fluctuation. Application of the model to the condition of fluctuating soil water content was performed and compared to the observation value at a given level of plant residue application and soil water content.
