My claim is that rather than a byproduct of colonization, wheat research served to remake Palestine as a biophysical region in need of improvement and colonization. I show how a shift in the plant sciences from research in taxonomy to plant breeding corresponded to an Keywords: agro-climatic shift on Palestine from an undesirable, arid region to a promising dryland agricultural Agro-climatology region. In this way, wheat research drew Palestine and the United States into a wider effort to transform Agro-ecology Colonization arid areas into agricultural drylands. Drawing on a previously unexplored episode of technical coopera- Palestine tion between researchers in the United States and Palestine, I argue that we must examine how wildness, United States native-ness, and agro-climatic suitability are scientifically constituted within and not apart from colonial Drylands conquest. In doing so, the paper calls for reconsideration within geography and political ecology of the place-making relationship between colonization and scientific practice. -
Testing Agricultural Impacts on Breeding Ground Food Resources As a Driver of Cuckoo Population Decline

I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other university. 1 2 Image: Charles Tyler “The first picture of you, The first picture of summer, Seeing the flowers scream their joy.” - The Lotus Eaters (1983) 3 4 Abstract The common cuckoo Cuculus canorus has undergone a striking divergence in population trend between UK habitats since the 1980s. The breeding population in Scotland – in largely semi-natural open habitat – shows significant increase whereas there has been a significant decline in England. Here breeding numbers have remained stable or increased in semi-natural habitats, while woodland and farmland populations have plummeted. As a brood parasitic bird with a long-distance annual migration, the cuckoo has a unique network of relationships to songbird „hosts‟, prey and habitat; and a disconnection between adult and nestling ecology due to lack of parental care. This thesis investigated the role of breeding ground land-use factors in driving cuckoo population decline. In the first chapter information was synthesised from the literature on potential threats and environmental impacts facing cuckoo populations, which also highlighted knowledge gaps and a basis for hypotheses in later chapters. -
Common-Scottish-Moths-Online
lea rn abo ut Scotlan d’s common moths Yellow Shell (Roy Leverton) Scotland has only 36 butterflies but around 1500 different moths. They can be found everywhere from sandy shores to the tops of Scotland’s highest mountains. Even a small urban garden can be visited by around 100 species. In fact, wherever there are plants there will be moths. Moths are fascinating and very easy to observe and study. This leaflet will help you identify some of the commonest and show you what you need to start “mothing ”. Moths have the same life-cycle as butterflies with four stages; 1. Egg (ovum) 2. Caterpillar (larva) 3. Pupa (chrysalis) 4. Adult (imago) They also both belong to the same order Lepidoptera derived from the Greek ‘ lepis’ = scale and ‘ pteron’ = wing, and have two pairs of wings. Moth Myths 1. All moths are dull, brown and less colourful than butterflies. This is simply not true. Several moths are very brightly coloured whilst others are cryptically marked and beautifully camouflaged. 2. All moths fly at night. Most species do but many only fly during the day, or fly both by day and night. 3. Only butterflies have clubbed antennae. Almost true, but the day-flying Burnet moths are the main exception to this rule possessing club-like antennae. 4. All moths eat clothe s. In Scotland only three or four of the c1500 species of moths do so and they prefer dirty clothes hidden away in the dark, and don’t like being disturbed or spring-cleaned! Macro or Micro? Moths are artificially divided into two groups; the macros (larger) and micros (smaller). -
Sites of Importance for Nature Conservation in Bridgend County
Sites of Importance for Nature Conservation in Bridgend County Borough Council SINC number:MG-1-M SINC name: Caerau West Grid reference: SS 846 938 Area (hectares): 62.09 Survey date: 06/09/2011 Surveyor name: Rebecca East Summary description A large dry acid grassland site with purple moor grass pasture in the more low lying areas. Species diversity increases in the wetter areas. The site also includes areas of dense bracken. Qualifying features Dry acid grassland Secondary features Purple moor grass and rush pasture Potential value/ unconfirmed features The site may be suitable for a range of invertebrate and bird species for feeding and possibly ground nesting. Smaller reptile species may be found here and amphibians may use the pools of standing water for breeding. Current condition and management (including problems and opportunities for biodiversity) Sheep, cattle and horses graze the area, fairly tightly in places which may limit the biodiversity value. Himalayan balsam is present in small parts of the site, particularly where past disturbance or tipping has taken place. The site may benefit from bracken control and limiting livestock numbers. Recommendations for future management: • Consider reducing grazing pressure on grassland • Removal of tipped material. • Control of invasive species. • Management of bracken. Additional information: A few areas of similar habitat beyond the SINC boundary could be surveyed in the furture with a view to designation.

Smuldersa, a Wageningen University & Research, Wageningen, The Netherlands b NIAB, Cambridge CB3 0LE, UK ARTICLE INFO ABSTRACT Keywords: A strict gluten-free diet is currently the only treatment for the 1–2% of the world population who suffer from Gluten coeliac disease (CD). However, due to the presence of wheat and wheat derivatives in many food products, Gliadin avoiding gluten consumption is difficult. Gluten-free products, made without wheat, barley or rye, typically T cell epitope require the inclusion of numerous additives, resulting in products that are often less healthy than gluten-based Coeliac disease equivalents. Here, we present and discuss two broad approaches to decrease wheat gluten immunogenicity for Plant breeding CD patients. The first approach is based on food processing strategies, which aim to remove gliadins or all gluten Food processing fi Mutation breeding from edible products. We nd that several of the candidate food processing techniques to produce low gluten- Genome editing immunogenic products from wheat already exist. The second approach focuses on wheat breeding strategies to remove immunogenic epitopes from the gluten proteins, while maintaining their food-processing properties. A combination of breeding strategies, including mutation breeding and possibly genome editing, will be necessary to produce coeliac-safe wheat. -
FSC Nettlecombe Court Nature Review 2014
FSC Nettlecombe Court Nature Review 2014 Compiled by: Sam Tuddenham Nettlecombe Court- Nature Review 2014 Introduction The purpose of this report is to review and share the number of different species that are present in the grounds of Nettlecombe Court. A significant proportion of this data has been generated by FSC course tutors and course attendees studying at Nettlecombe court on a variety of courses. Some of the data has been collected for the primary purpose of species monitoring for nationwide conservation charities e.g. The Big Butterfly Count and Bee Walk Survey Scheme. Other species have just been noted by members or staff when out in the grounds. These records are as accurate as possible however we accept that there may be species missing. Nettlecombe Court Nettlecombe Court Field Centre of the Field Studies Council sits just inside the eastern border of Exmoor national park, North-West of Taunton (Map 1). The house grid reference is 51o07’52.23”N, 32o05’8.65”W and this report only documents wildlife within the grounds of the house (see Map 2). The estate is around 60 hectares and there is a large variety of environment types: Dry semi- improved neutral grassland, bare ground, woodland (large, small, man –made and natural), bracken dominated hills, ornamental shrubs (lawns/ domestic gardens) and streams. These will all provide different habitats, enabling the rich diversity of wildlife found at Nettlecombe Court. Nettlecombe court has possessed a meteorological station for a number of years and so a summary of “MET” data has been included in this report. -
Carmarthenshire Moth & Butterfly Group
CARMARTHENSHIRE MOTH & BUTTERFLY GROUP NEWSLETTER ISSUE No.2 JUNE 2006 Editor: Jon Baker (County Moth Recorder for VC44 Carms) INTRODUCTION Welcome to the 2 nd newsletter of the VC44 Moth & Butterfly Group. I received a positive reaction to the 1 st one, so I have decided to continue this experiment, and expand on it. In this edition I have included a couple of articles, as well as looking at some of the recent records in more detail. June has been a notably hot month. Sitting here in sweltering heat at the start of July, I look back on what has been a cracking month for mothing. A good range of our native species has been recorded so far this year, but it has also been an exceptionally good month for migration. Although the south coast of England has fared much better than us, a few things have made it here. A summary of migrant moths can be found below. I’ve decided not to continue including full lists of micro moths recorded, as this is really not of widespread interest, and time and space can be better used elsewhere. If anyone does wish to discuss micros with me, feel free to ask anything. Similarly, as I do not actually receive records of Butterflies, I cannot really do a formal write up of those in these bulletins – although I will continue to mention any personal highlights of those of others that I am aware of. At the end of this edition are a couple of informal articles. One looking at the status of Mouse Moth in the county, the other an identification workshop on the tricky group of “white waves”. -

Our experimental evidence showed that there were no genotypes with effective resistance single- genes among the lines tested. Effective powdery mildew resistance from start to end of vegeta- tion season depended on the quantitative resistance level. The most resistant lines were evalu- ated with a score of 2 and area under the disease progress curve (AUDPC) values ranging between 1.0–5.4. The most susceptible genotypes from the collection nurseries had score 8–9 and AUDPC values ranging between 1350–2220. The correlations between maximal disease se- verity and AUDPC values were strong (r = 0.79–0.92). Genotypes with AUDPC values up to 10 represented 93 lines or 7% in the check trial nursery and 22 lines or 9% in the competitive trial nursery. Lines evaluated with a score 4–5 and AUDPC value 100–300 dominated in 2004. In the next year the dominant genotypes had resistance scores 3–4 and AUDPC value 50–200.
