The role of ecotoxicology for monitoring ecosystem health

The proposed EC Water Framework Directive (WFD)incorporates some new concepts in the field of water protection. Most of these concepts rely on the use of applied ecology of water systems. The expected improvement of environmental management is very new in this context. The new WFD will allow the checking of the eco-epidemiological results of several human impacts on aquatic ecosystems, such as toxic pollution and habitat modification. This paper intends to show some consequences of the WFD in the field of ecotoxicology.

Some statistical aspects of the long-term gill net monitoring programme for pike Esox lucius in Windermere (English Lake District)

For more than 55 years, data have been collected on the population of pike Esox lucius in Windermere, first by the Freshwater Biological Association (FBA) and, since 1989, by the Institute of Freshwater Ecology (IFE) of the NERC Centre for Ecology and Hydrology. The aim of this article is to explore some methodological and statistical issues associated with the precision of pike gill net catches and catch-per-unit-effort (CPUE) data, further to those examined by Bagenal (1972) and especially in the light of the current deployment within the Windermere long-term sampling programme. Specifically, consideration is given to the precision of catch estimates from gill netting, including the effects of sampling different locations, the effectiveness of sampling for distinguishing between years, and the effects of changing fishing effort.

The EC Water Framework Directive and monitoring lakes in the Republic of Ireland

The authors of the article explore and discuss the effects of implementing the EC Water Framework Directive (WFD) in the Republic of Ireland. They also summarise some of the findings from a survey of 31 lakes sampled regularly between March 1996 and December 1997. The lakes were sampled regularly for a range of physico-chemical and biotic variables that probably would be important for monitoring programmes implemented under the WFD. The authors discuss problems of monitoring lake types with varying seasonal patterns.

A decade of monitoring and management of freshwater algae, in particular Cyanobacteria, in England and Wales

Although the toxicity of cyanobacteria has been known for many years, cyanobacteria-related problems in the UK were generally limited in frequency. However, this all changed and became of national concern following the exceptional environmental conditions in the autumn of 1989, when widespread cyanobacterial blooms and scums developed in fresh waters. This paper summarises the Environment Agency's monitoring programme for freshwater algae since 1991 and describes the actions the Environment Agency has taken as a result of the monitoring data.

High-resolution automatic water quality monitoring systems applied to catchment and reservoir monitoring

Automatic recording instruments provide the ideal means of recording the responses of rivers, lakes and reservoirs to short-term changes in the weather. As part of the project ‘Using Automatic Monitoring and Dynamic Modelling for the Active Management of Lakes and Reservoirs', a family of three automatic monitoring stations were designed by engineers at the Centre for Ecology and Hydrology in Windermere to monitor such responses. In this article, the authors describe this instrument network in some detail and present case studies that illustrate the value of high resolution automatic monitoring in both catchment and reservoir applications.

New challenges in lake and river monitoring

Freshwater ecosystems are highly dynamic and change on time-scales that range from a few hours to several months. The development of models that simulate these processes is often hampered by the lack of sufficient data to parameterize the processes and validate the models. In this article, I review some of the challenges posed by this lack of information and suggest ways in which they can be met by using automatic monitoring systems. One of these studies is the project tempQsim (EVK1-CT2002-00112) funded by the European Commission. In this project, detailed field and model analyses have been performed at eight catchment study sites in south and south-east Europe. A number of perceptual models for the study sites have been established, and results are being used to improve selected catchment models and provide a more adequate description of pollution dynamics. Results from the extensive field studies and model tests are now being used to derive recommendations for more tailored monitoring concepts in highly dynamic, but ‘data scarce’ environments, such as are frequently found in Mediterranean river basins. The author includes implications of the EU Water Framework Directive on monitoring methods.

Plan de marketing de una PYME : Abereen Klinikak

Ante el reciente aumento del dinamismo y la globalización en los mercados, los análisis, estrategias y planes de acción están adquiriendo una mayor importancia para todas las empresas. En una economía cambiante, anticiparse a los cambios y estar preparados para nuevas realidades es un objetivo prioritario de las empresas. El plan de marketing es un medio más para conseguir anticiparse a las nuevas características de los mercados. Cada empresa tiene características diferentes, por lo que es necesario que el plan se adapte a la organización y no al revés. Por ejemplo, en las grandes empresas se ha mostrado como un arma comercial determinante, pero en las PYMES puede convertirse incluso en un sustitutivo de la planificación estratégica. En éste trabajo se realizará un plan de marketing en la práctica para “Abereen Klinikak”, una PYME del sector veterinario, aplicando el método analítico sintético. Se realizará un análisis previo del mercado y un diagnóstico de la situación de la empresa, se marcarán los objetivos, estrategias y acciones a seguir, y se implantará un plan de control y seguimiento de ellos. Todo ello desde una forma estructurada y sistematizada, con el fin de seguir la mejor estrategia comercial posible para la empresa. Abstract Due to the recent increase of dynamism and market globalization, analyzes, strategies and action plans are becoming increasingly important for all businesses. In a changing economy, to anticipate changes and be prepared for new realities is a priority for companies. The marketing plan is another way of being able to anticipate the new market characteristics. Each company has different characteristics, so it is necessary that the marketing plan suits the organization and not vice versa. For example, in large companies it has been shown as a key commercial weapon, but for SMEs it could even become a substitute for strategic planning. In this project a marketing plan for "Abereen Klinikak", an enterprise which belongs to the SME sector, will be implemented. The marketing plan will be put into practice using the synthetic analytical method. To do so, preliminary market analysis and an assessment of the company’s situation will be done. Furthermore, goals, strategies and action steps will be scored, and a control and monitoring plan will be implemented. The plan will be put into practice in a structured and systematic way, in order to follow the best business strategy for the company.
