On the imperfections of experimental-psychological research

Mass experiment in the field of psychological research has already won the right to exist, and even the question of choosing a method is gradually losing its former urgency, despite the emergence of a number of new methods. True, there can be no talk of a single method, or at least the coordination and unification of the methods proposed and still practiced; it is even possible that there will be no need for this, due to local conditions, such as: the peculiarities of the task, the properties of human material, the fitness of the laboratory, and finally, due to personal preference for one particular technique; but one thing will remain constant and common for all conditions and research schools the need to carry out experiments, firstly, by completely reliable personnel, and secondly, with the most correct and scientifically pure formulation of experiments.</jats:p

Large carabid beetle declines in a United Kingdom monitoring network increases evidence for a widespread loss in insect biodiversity

1. Carabid beetles are important functional components of many terrestrial ecosystems. Here, we describe the first long-term, wide-scale and quantitative assessment of temporal changes in UK carabid communities, to inform nationwide management aimed at their conservation. 2. Multivariate and mixed models were used to assess temporal trends over a 15-year period,across eleven sites in the UK Environmental Change Network. Sites covered pasture, field margins, chalk downland, woodland and hedgerows in the lowlands, moorland and pasture in the uplands, and grassland, heaths and bogs in montane locations. 3. We found substantial overall declines in carabid biodiversity. Three-quarters of the species studied declined, half of which were estimated to be undergoing population reductions of >30%, when averaged over 10-year periods. Declines of this magnitude are recognized to be of conservation concern. They are comparable to those reported for butterflies and moths and increase the evidence base showing that insects are undergoing serious and widespread biodiversity losses. 4. Overall trends masked differences between regions and habitats. Carabid population declines (10-year trend, averaged across species) were estimated to be 52% in montane sites,31% in northern moorland sites and 28% in western pasture sites (with at least 80% of species declining in each case). Conversely, populations in our southern downland site had 10-year increases of 48% on average. Overall, biodiversity was maintained in upland pasture, and populations were mostly stable in woodland and hedgerow sites. 5. Synthesis and applications. Our results highlight the need to assess trends for carabids, and probably other widespread and ubiquitous taxa, across regions and habitats to fully understand losses in biodiversity. Land management should be underpinned by a consideration of how wide-scale environmental drivers interact with habitat structure. The stability of population trends in woodlands and hedgerows of species that are declining elsewhere puts these habitats at the fore-front of integrated landscape management aimed at preserving their ecosystem services
