Abstract

We estimated the sensitivity of terrestrial ecosystem respiration to air temperature across 60 FLUXNET sites by minimizing the effect of seasonally confounding factors. Graf et al. now offer a theoretical perspective for an extension of our methodology. However, their critique does not change our main findings and, given the currently available observational techniques, may even impede a comparison across ecosystems.

Abstract

The involvement of the public in decision-making is established as a key feature of many planning policies. However, there is evidence from the literature of a prevailing gap between participation rhetoric on paper and participation at the operational level. We assess whether this is also the case with landscape policy and review landscape characterization and assessment initiatives in England, Norway, Slovakia and Malta, focusing on five dimensions of good practice: (i) scope of public participation, (ii) representativeness of those involved, (iii) timeliness of public involvement, (iv) extent to which participation is rendered comfortable and convenient for the public, and (v) eventual influence of public input on decisions. Reviewed reporting results indicate weaknesses in the implementation of public participation, with public involvement largely limited to consultation, with few efforts to ensure representativeness of participants, with predominantly late involvement of the public, and with limited influence of the public on outputs. Furthermore, few efforts appear to be made to facilitate participation for the public. Although the cases studied differ, none of them are fully satisfactory in relation to the European Landscape Convention's participatory targets. The reporting of public participation processes thus suggests that practices may fail to match the rhetoric.

Abstract

Fungal hyphae in soil, although crucial in the C-dynamics, are difficult to quantify. Here we present a simple method for fungal biomass assessment and possibility for up-scaling. Originally we used root nets to quantify fine roots in drought-stressed Picea abies stand as described by Lukac and Godbold (2010).Root nets (7 cm wide, mesh size 1 mm) were inserted vertically to 20 cm depth, twice during the course of one year. When root nets were extracted from the soil, large amounts of hyphae were growing on and through the nets in the control plot, whereas little or no hyphae were growing in nets from the drought-stressed plot.This observation led us to consider root nets as a promising tool to quantify hyphae as well. The inert net material together with its regular geometric pattern is well suited for obtaining fungal biomass estimates and provide a material for further molecular analysis of fungal species. We will describe a proposal how to scan the hyphae, calculate the biomass and upscale to the soil volume unit.
