The Relationship

One of the main goals of monitoring cyanobacteria blooms in aquatic environments is to reveal the relationship between cyanobacterial abundance and environmental variables. Studies typically correlate data that were simultaneously sampled. However, samplings occur sparsely over time and may not reveal the short-term responses of cyanobacterial abundance to environmental changes. In this study, we tested the hypothesis that stronger cyanobacteria x environment relationships in monitoring are found when the temporal variability of sampling points is incorporated in the statistical analyses. To this end, we investigated relationships between cyanobacteria and seven environmental variables that were sampled twice yearly for three years across 11 reservoirs, and data from an intensive monitoring in one of these reservoirs. Poor correlations were obtained when correlating data simultaneously sampled. In fact, the 'highly recurrent' role of phosphorus in cyanobacteria blooms is not properly observed in all sampling periods. On the other hand, the strongest correlation values for the total phosphorus x cyanobacteria relationship were observed when we used the variation of sampling points. We have also shown that environment variables better explain cyanobacteria when a time lag is considered. We conclude that, in cyanobacteria monitoring, the best approach to reveal determinants of cyanobacteria blooms is to consider environmental variability.

Abstract Bernal, M., Stratoudakis, Y., Wood, S., Ibaibarriaga, L., Uriarte, A., Valdés, L., and Borchers, D. 2011. A revision of daily egg production estimation methods, with application to Atlanto-Iberian sardine. 2. Spatially and environmentally explicit estimates of egg production. – ICES Journal of Marine Science, 68: . A spatially and environmentally explicit egg production model is developed to accommodate a number of assumptions about the relationship between egg production and mortality and associated environmental variables. The general model was tested under different assumptions for Atlanto-Iberian sardine. It provides a flexible estimator of egg production, in which a range of assumptions and hypotheses can be tested in a structured manner within a well-defined statistical framework. Application of the model to Atlanto-Iberian sardine increased the precision of the egg production time-series, and allowed improvements to be made in understanding the spatio-temporal variability in egg production, as well as implications for ecology and stock assessment.

 Functional diversity is one of the crucial aspects of the functioning of ecosystems and the provision of ecosystem services. In this review paper, we analyze how biodiversity contributes to human well-being through the provision of goods and ecosystem services, and related aspects of ecological processes and their relationship with the functional diversity of ecosystems are presented. It aims to explain in a simple way, the concepts related to functional diversity, the importance of the functional groups and the role of functional traits of the species as a key element in the responses of organisms to environmental changes. Understanding the relationship between ecosystem processes, functional diversity of species and providing ecosystem services, allow better management of natural ecosystems and their biodiversity, enabling conservation and sustainable use of different types of services provided by ecosystems.

Effective leaders who have the capacity to solve complex, strategic business problems are a key differentiator in the new world of work. As external environmental changes converge with internal organisational shifts, the need for a strong bench of leaders becomes critical in driving profitable growth. This study explores the relationship between personality and the capacity to think strategically, an important component of managing the complexity of the emerging environment. Based on the California Psychological Inventory and Career Path Appreciation assessments of 256 managers and executives, the existence of relationships between a number of personality factors and the respondents’ future potential capability (FPC) were tested to identify which personality factors are predictors of the potential to think strategically. Anchored in Complexity Leadership Theory (CLT), this research builds on the leadership functions of CLT to provide new insight into the role of individual characteristics in the ability to think strategically. The consolidated findings identified Dominance, Flexibility, Achievement via Independence, Psychological Mindedness and Self-Acceptance as key constructs in the ability to think strategically. These outcomes sharpen the new leadership profile and enable the development of tools that can directly improve the organisation’s ability to identify, attract, select and develop leaders who are proficient in the emergent, complex context.

The continuous innovation and development of information technology and information infrastructure has driven the evolution of the supply form, and with the emergence of 5G, a mobile integrated communication system that includes communication access, interconnection, and connectivity of things, it has now evolved to a modern supply chain of the social organization collaborative type. This paper briefly describes the process of supply chain development, examines the role of communication technology in driving supply chain development, discusses the relationship between modern supply chain and social development and the support of 5G for modern supply chain, and illustrates the application of 5G in modern supply chain scenarios by reducing information time lag in market-side scenarios as an example.

This article explores both state-based regulation and self-regulation, shared narratives, and lessons to better understand the interaction of these two forms of regulation in the nonprofit space. “The Context” section outlines six preliminary research questions that inform the work. “The Framework” section then outlines the regulatory framework, focusing on various regulatory motivations, before “The Findings” section turns to country findings. In unpacking some of the major findings, we look first at state perspectives on the role of regulation before considering the sector’s perspective. Taking both on board enables us to configure the relationship spectrum between state and sector when it comes to regulation and to begin to identify, based on the 16 case studies undertaken, the most common triggers for regulatory change identified therein and to reframe them through the development of a series of five regulatory propositions and seven environmental variables to help understand how different forms of regulation are triggered and interact.

Studies have shown that environmental variables significantly affect variation in stock abundance of marine populations. The northern Gulf of California (NGC) is a highly productive region of interest due to its fish resources and diversity. Conservation of the marine species inhabiting the region is of public interest. Our study analysed the influence of physical environmental factors on several commercial marine species, using catch per unit effort (CPUE) as a proxy for abundance. Generalized additive models were used to test the significance of selected environmental variables on stock abundance. Deseasonalized cross-correlation analysis was used to examine time-lagged correlations between CPUE and abiotic variables to identify response timings. The results suggest that for most commercial species the sea surface temperature and the long-term climate Pacific Decadal Oscillation index are the predominant predictors for species abundance, followed by the Colorado River discharge. The Multivariate ENSO Index and the Pacific-North American pattern indices also showed specific effects on certain species. The NGC is a highly dynamic region, where species respond to environmental changes according to the characteristics of their life histories.

Moderating Role

The interpretation of managers of environmental changes helps in identifying the gaps between the environment and a firm’s capabilities. This in turn can support a firm’s ability to use dynamic capabilities in an effective way to reconfigure the firm’s resources into new operational capabilities that better match the environment and to exploit environmental opportunities. However, extant studies have ignored the moderating role of managers’ interpretation of environmental changes in the capabilities building paradigm. This study empirically examines the moderating role of environmental interpretation in the relationship between dynamic capabilities and improvement capabilities. To operationalise environmental interpretation to enable the development of a measurable model for this construct, which has yet to be developed, 209 large manufacturing firms were selected as a sample to study the relationship between environmental interpretation and firm’s capabilities. By applying the PLS-SEM technique, this study finds that environmental interpretation moderates the relationship between learning capability, integrating capability and coordinating capability and improvement capability.

The Relationship

In order to adapt to daily environmental changes, especially in relation to light availability, many organisms, such as plants, developed a vital mechanism that controls time-dependent biological events: the circadian clock. The circadian clock is responsible for predicting the changes that occur in the period of approximately 24 hours, preparing the plants for the following phases of the cycle. Some of these adaptations can influence the response of weeds to the herbicide application. Thus, the objectives of this review are to describe the physiological and genetic mechanisms of the circadian clock in plants, as well as to demonstrate the relationship of this phenomenon with the effectiveness of herbicides for weed control. Relationships are described between the circadian clock and the time of application of herbicides, leaf angle and herbicide interception, as well as photosynthetic activity in response to the circadian clock and herbicide efficiency. Further, it is discussed the role of phytochrome B (phyB) in the sensitivity of plants to glyphosate herbicide. The greater understanding of the circadian clock in plants is essential to achieve greater efficiency of herbicides and hence greater control of weeds and higher crop yields.

The Relationship

Phenolics are the most abundant plant metabolites and are believed to decompose slowly in soils compared to other soil organic matter (SOM). Thus, they have often been considered as a slow carbon (C) pool in soil dynamics models. Here, however, we review changes in our concept about the turnover rate of phenolics and quantification of different types of phenolics in soils. Also, we synthesize current research on the degradation of phenolics and their regulatory effects on decomposition. Environmental changes, such as elevated CO2, warming, nitrogen (N) deposition, and drought, could influence the production and form of phenolics, leading to a change in SOM dynamics, and thus we also review the fate of phenolics under environmental disturbances. Finally, we propose the use of phenolics as a tool to control rates of SOM decomposition to stabilize organic carbon in ecosystems. Further studies to clarify the role of phenolics in SOM dynamics should include improving quantification methods, elucidating the relationship between phenolics and soil microorganisms, and determining the interactive effects of combinations of environmental changes on the phenolics production and degradation and subsequent impact on SOM processing.

The Relationship

The sugarcane sector has been gaining more importance in both Brazilian and World economies, even though it has had a lack of agricultural investments and climate issues has generated questionings about the future of the sector. To analyse this trend, the present work was based on the following growth strategies: internal growth, horizontal integration, diversification, and vertical integration. The objective of the present research is to assess the relationship between these types of strategies and macro-environmental variables in order to determine any possible correlation. Bibliographic and documental survey on the behaviour of macro-environment variables was carried out. The Pearson’s correlation test was used to identify the relationship between these variables and growth strategies. It was possible to observe that each type of growth strategy is related to one specific type of variable, which is exclusive to each strategy, except in the case of diversification. That is, electric energy prices have a correlation with internal growth and the real growth rate is correlated with horizontal growth. None of these macro-environmental variables repeated in other growth strategies. The only exception was the diversification strategy, which was correlated with eight variables, with five of these being exclusive to this type of strategy.
