A new substrate for sampling deep river macroinvertebrates

We compared macroinvertebrate communities colonising multiplate samplers constructed from perspex or tempered hardboard (wood) with an alternative artificial substrate constructed from folded coconut fibre matting (coir) enclosed in nylon netting. Substrates were incubated for 62 days over January to March 2007 at six sites over 240 km along the Waikato River. The three substrates supported similar numbers of invertebrate taxa (27 - 29 taxa), but coir samples contained 71% of total invertebrate numbers from all substrates combined, compared with <17% for each type of multiplate sampler. Coir faunas were heavily dominated by the hydrobiid snail Potamopyrgus (84 % of numbers), and this taxon along with the amphipod Paracalliope comprised 58 - 66 % of invertebrates on both types of multiplate samplers. Analysis of a Bray-Curtis matrix suggested statistically significant differences in percent community composition between coir samplers and each type of multiplate sampler over the late summer study period. Densities per cm3 of Oligochaeta, Mollusca, and "other worms" (Platyhelminthes, Rhabdocoela, Nemertea and Hirudinea combined) were significantly higher in coir samples than one or both of the multiplate samplers. Results suggest coir samplers may provide a useful supplement to multiplate samplers for deep river invertebrate studies by collecting a different range of taxa, including those favouring cover and characteristic of depositional environments

Delivering job search services in rural labour markets: the role of ICT

This paper reports original research on job seekers in two contrasting rural areas in Scotland: one a remote rural area; the other semi-rural with strong metropolitan connectivity. It seeks to answer two key questions. Firstly, what are the potential benefits and barriers associated with the delivery of services for rural job seekers through the use of Information and Communications Technology (ICT)-based systems? And following from this, what is the nature and extent of the 'digital divide' affecting unemployed job seekers and what policies are required to address this problem? Rural labour markets in the United Kingdom, like those across Europe, have recently experienced a period of continuous and rapid change. The decline of primary sector industries has been accompanied by increases in service employment, especially in tourism. However, in the UK, as elsewhere, this economic transition has not been without its difficulties. Whilst social exclusion is less prevalent in rural areas than in many cities, instances f poverty remain. Unemployment, and particularly long-term unemployment, has been cited as an important factor explaining the continuing problem of social exclusion in many rural areas. Recent research has suggested that an important barrier to work faced by unemployed people in rural areas relates to the absence of locally-based job search and advice services. The Employment Service (the main public agency in the UK dealing with job seekers) has argued thagiven the remote and sparsely populated nature of many rural labour markets, ICT-based job search and advice services (e.g. delivered through telephone helplines and the Internet) may offer the most efficient and cost-effective policy solution in many areas. However, the viability of this policy is dependent on the level of ICT awareness and access among job seekers. Interviews were conducted with over 400 job seekers in the two areas. The Caithness and Sutherland area in northern Scotland is among the most remote and least densely populated in Europe, with unemployment rates well above the national average. West Lothian, in contrast, is situated near to Scotland's economic centre and is a major centre of manufacturing activity with unemployment below the national average. The interviws examined the level of ICT skills possessed, attitudes towards and access to ICT, and additionally collected information on a range of personal skills and attitudes. Evidence of relatively low levels of ICT awareness and access was found in both communities Although those residing in the more remote study area were also more likely to have Internet access, a significant minority did not even have access to a telephone at home. The paper concludes that, if ICT is to prove to be the waforward in delivering services for job seekers in rural areas, community-based access and support facilities must be provided, along with appropriate training for job seekers in basic and higher level ICT skills.
