Agri‐environment schemes (AES) have been criticized for being inadequately monitored and for not delivering the expected benefits to nature. Consequently, the Welsh Government funded a comprehensive ...programme of monitoring of AES between 2009 and 2012. The AES assessment focused on Tir Gofal (which translates as “Land in Care”) but also included the Organic Farming Scheme, and monitoring focused on a range of taxa of conservation importance: arable plants, grassland fungi, bats (six species), butterflies (three species), birds (five species), water vole and brown hare.
Field surveys were carried out on matched farms and fields within and outside of AES. Response variables were spatial trends of abundance, occurrence and species richness, and were modelled against AES status. Existing data were also available for two bird species.
Few differences were observed between AES and non‐AES farms and fields. Those that were observed were for species that use arable habitats (which are uncommon in Wales): arable plants, yellowhammers and brown hares. The lack of differences in non‐arable habitats may reflect the smaller contrast between AES and non‐AES management in these habitats. It may also reflect the original condition of habitat entered into AES prescriptions, as most non‐arable prescriptions were defined by mandatory management of existing habitats, rather than optional habitat creation or restoration, which is the case for most arable prescriptions.
Despite the lack of differences observed, AES may help to maintain populations of species, making it more likely that they will persist in the landscape. There is evidence, from this monitoring programme and elsewhere, that AES can increase the populations of species, when well targeted and implemented.
Policy implications. Our results indicate that Welsh Agri‐environment schemes (AES) have been only partly successful in achieving their stated aim of “maintaining and enhancing species abundance”. They can be used to improve AES design and management, both in Wales and more widely, by identifying and promoting effective management interventions, and by identifying ineffective management interventions and seeking alternatives. Comprehensive monitoring of AES, combined with specific targets regarding expected outcomes, is essential to determine whether AES are providing value for money.
The Glastir Monitoring and Evaluation Programme (GMEP) ran from 2013 until 2016 and was probably the most comprehensive programme of ecological study ever undertaken at a national scale in Wales. The ...programme aimed to (1) set up an evaluation of the environmental effects of the Glastir agri-environment scheme and (2) quantify environmental status and trends across the wider countryside of Wales. The focus was on outcomes for climate change mitigation, biodiversity, soil and water quality, woodland expansion, and cultural landscapes. As such, GMEP included a large field-survey component, collecting data on a range of elements including vegetation, land cover and use, soils, freshwaters, birds, and insect pollinators from up to three-hundred 1 km survey squares throughout Wales. The field survey capitalised upon the UK Centre for Ecology & Hydrology (UKCEH) Countryside Survey of Great Britain, which has provided an extensive set of repeated, standardised ecological measurements since 1978. The design of both GMEP and the UKCEH Countryside Survey involved stratified-random sampling of squares from a 1 km grid, ensuring proportional representation from land classes with distinct climate, geology and physical geography. Data were collected from different land cover types and landscape features by trained professional surveyors, following standardised and published protocols. Thus, GMEP was designed so that surveys could be repeated at regular intervals to monitor the Welsh environment, including the impacts of agri-environment interventions. One such repeat survey is scheduled for 2021 under the Environment and Rural Affairs Monitoring & Modelling Programme (ERAMMP).

Certain ancient Near Eastern texts develop over time towards a reasonably stable state of transmission. However, the development towards a single ‘stabilised’ transmitted form that marks the ...biblical manuscripts between the second century B.C.E. and second century C.E. is often considered to permit the Hebrew bible a unique position in the ancient Near Eastern textual corpus. The degree to which the wider body of ancient Near Eastern texts actually support or undermine this position is the topic of this dissertation. The study begins by formulating a methodology for comparing the accuracy with which ancient texts of varying genres and languages were transmitted. Exemplars from the first millennium B.C.E. cuneiform evidence are selected for analysis on the basis of genre. Texts that are preserved in more than one ancient copy are compared to determine how much variation occurs between manuscripts of the same text. The study begins with representative texts from the Neo-Assyrian, Neo-Babylonian and Late Babylonian periods that range in date from the late eighth century B.C.E. to the third century B.C.E. The study then turns to the Torah scrolls from the Dead Sea area that range in date from the third century B.C.E. to the second century C.E. The accuracy with which the cuneiform texts were transmitted is then compared with the biblical evidence. The study finds that the most stable texts surveyed are those containing ritual instructions. The mechanisms that may have led to the exact transmission of the Torah in the late Second Temple period are discussed in the conclusion.
Movement disorders occur in some patients with cerebral toxoplasmosis with HIV-1 infection. Such movement disorders have not been described in patients with cerebral toxoplasmosis without HIV-1 ...infection. This report discusses their diagnostic features, aspects of management, and possible mechanisms underlying the pathogenesis of the movement disorders.
