Abstract Enterprise Risk Management (ERM) is the discipline by which enterprises monitor, analyze, and control risks from across enterprise, with goal of identifying underlying correlations thus optimizing risk‐taking behavior in a portfolio context. This study analyzes valuation implications ERM Maturity. We use data industry leading Insurance Society Maturity Model over period 2006 to 2011, scores firms on five‐point maturity scale. Our results suggest that have reached mature levels are...
Soil microorganisms are an important indicator of soil fertility and health. However, our state knowledge about microbial activities, community compositions carbon use patterns under metal contaminations is still poor. This study aimed to evaluate the influences heavy metals (Cd Pb) on by investigating composition preferences. Metal pollution was approached both singly jointly with low (25 2500 mg kg−1) high (50 5000 concentrations Cd Pb, respectively, in artificially contaminated soil. In a...
Abstract The capacity for terrestrial ecosystems to sequester additional carbon (C) with rising CO 2 concentrations depends on soil nutrient availability 1,2 . Previous evidence suggested that mature forests growing phosphorus (P)-deprived soils had limited extra biomass under elevated (refs. 3–6 ), but uncertainty about ecosystem P cycling and its response represents a crucial bottleneck mechanistic prediction of the land C sink climate change 7 Here, by compiling first comprehensive budget...
This study integrates the constructs of organisational change strategies, market orientation, top management behaviour, leadership style, learning orientation and business perfor Mance. A survey was sent to 2,000 organisations within Australia, as defined by annual revenue. Data analysed using two‐stage least squares regression (2SLS). Findings indicate that both planned emergent strategies significantly influence orientation. Results also style impact on a Finally, results is positively...
Network and multivariate statistical analyses were performed to determine interactions between bacterial fungal community terminal restriction length polymorphisms as well soil properties in paired woodland pasture sites. Canonical correspondence analysis (CCA) revealed that shifts composition correlated with dissolved organic carbon, while changes moisture, nitrogen phosphorus. Weighted correlation network detected two distinct microbial modules per land use. Bacterial ribotypes did not...
Plants and microorganisms intensely compete for nitrogen (N) at many stages of the terrestrial N cycle. In particular, dissolved organic (DON) pool, competition low molecular weight (LMWDON) compounds such as amino acids peptides (and LMW matter; LMWDOM a whole) has received significant recent research interest. However, LMWDON contain both carbon (C), question that remains is whether soil are primarily taking up mainly C or contained therein. We investigated microbial uptake rates model...
Nitrogen is a key regulator of primary productivity in many terrestrial ecosystems. Historically, only inorganic N (NH4+ and NO3-) L-amino acids have been considered to be important the nutrition plants. However, amino are also present soil as small peptides D-enantiomeric form. We compared uptake assimilation free acid short homopeptide both L- forms. Sterile roots wheat (Triticum aestivum L.) plants were exposed solutions containing either 14C-labelled L-alanine, D-alanine, L-trialanine or...
Anthropogenic nitrogen inputs cause major negative environmental impacts, including emissions of the important greenhouse gas N
Summary Mycorrhizal fungi associated with boreal trees and ericaceous shrubs are central actors in organic matter (OM) accumulation through their belowground carbon allocation, potential capacity to mine for nitrogen (N) ability suppress saprotrophs. Yet, interactions between co‐occurring ectomycorrhizal (EMF), ericoid mycorrhizal (ERI), saprotrophs poorly understood. We used a long‐term (19 yr) plant functional group manipulation experiment removals of tree roots, mosses analysed the...
Estuaries in rainfall poor regions are highly susceptible to climatic and hydrological changes. The Coorong, a Ramsar-listed estuarine-coastal lagoon at the end of Murray-Darling Basin (Australia), has experienced declining ecological health over recent decades. Twenty years environmental data were analysed assess patterns drivers water quality Large areas Coorong now persistently hyper-saline (salinity >80 psu) hypereutrophic (total nitrogen, TN > 4 mg L-1, total phosphorus, TP 0.2...
