An earlier software application of ours, TetraploidMap for Windows, enabled linkage analysis and quantitative trait locus interval mapping to be carried out in an experimental cross autotetraploid species, using both dominant markers such as amplified fragment length polymorphisms codominant simple sequence repeats. The size was limited 800 markers, conducted each parent separately due the difficulties obtaining a reliable consensus map 2 parents. Modern genotyping technologies now give rise...
Aphids are abundant in natural and managed vegetation, supporting a diverse community of organisms causing damage to agricultural crops. Due changing climate, periods drought anticipated increase, the potential consequences this for aphid-plant interactions unclear.Using meta-analysis synthesis approach, we aimed advance understanding how increased incidence will affect ecologically economically important insect group characterize any underlying mechanisms. We used qualitative quantitative...
Abstract Conserving genetic diversity in animal populations is important for sustaining their ability to respond environmental change. However, the “between-population” component of (biocomplexity) threatened many exploited populations, particularly marine fish, where harvest management regions may be larger than spatial extent genetically distinct subpopulations. Using single-nucleotide polymorphism data, we delineated geographic limits three population units Atlantic cod (Gadus morhua)...
Emamectin benzoate is used as an in-feed treatment for the control of sea lice parasites in all main farmed Atlantic salmon (Salmo salar) facilities worldwide (Norway, Chile, Scotland and Canada). Investigations into its effect on non-target benthic fauna resulting from excretion fish uneaten feed have been limited. This paper presents findings a study that intended to assess impact emamectin using new low detection method benzoate. Eight farms Shetland Isles, were surveyed, with sediment...
The changing climate is altering timing of key fruit ripening processes and increasing the occurrence defects. To improve our understanding genetic control raspberry development an enhanced linkage map was developed used to examine phenotypic data.In this study we for cvs. Glen Moy x Latham reference mapping population using genotyping by sequencing (GbS). Alignment a newly sequenced draft genome red raspberry, cultivar (cv.) Moy, identified 8019 single nucleotide polymorphisms (SNPs). After...
Abstract Potato Cyst Nematodes (PCN) are a globally important and economically extremely damaging potato pest. Chemical control has limited impact cannot clear field of PCN, but genetic resistance in potatoes is an effective part natural management PCN. There two closely related species PCN; Globodera rostochiensis against which the H1 gene from S. tuberosum ssp. andigena (CPC 1673) proven Europe for several decades, G. pallida varieties with also commercially available. However, resistant...
All animals and plants are, to some extent, susceptible disease caused by varying combinations of parasites, viruses bacteria. In this paper, we present a mathematical model interactions between host, two parasitoids pathogen which shows that the presence an infection can preserve promote diversity in such multi-species systems. Initially, use system ordinary differential equations investigate species parasitoids, host infection. We show all four is necessary for as whole persist,...
SUMMARY A range of wheat cultivars, including elite older cultivars and some preferred by organic growers, were trialled under high low nitrogen (N) conventional conditions to determine whether that yield highly have the same relative conditions. cultivar mixtures was also assessed see these gave advantages or superiority in either farming system. The trials grown with without full fungicide programmes, which largely controlled disease. Amongst Alchemy showed superior as did Pegassos, but...
Abstract Understanding soil systems is critical because they form the structural and nutritional foundation for plants thus every terrestrial habitat agricultural system. In this paper, we encourage increased use of mathematical models to drive forward understanding interactions in ecological systems. We discuss several distinctive features ecosystems empirical studies them. explore some perceptions that have previously deterred more extensive ecology advances already been made using...
Aphid populations frequently include phenotypes that are resistant to parasitism by hymenopterous parasitoid wasps, which is often attributed the presence of 'protective' facultative endosymbionts residing in aphid tissues, particularly Hamiltonella defensa. In field conditions, under pressure, observed coexistence aphids with and without protective symbionts cannot be explained their difference fitness alone. Using cereal Rhopalosiphum padi as a model, we propose an alternative mechanism...
The risk of between‐field spread disease is typically omitted from crop warning systems, as it difficult to know the number and location inoculum sources thus predict abundance arriving at healthy crops. This study explores utility a simple approach predicting spread, based on estimated probability that will survive transportation process. Using potato late blight case study, effect solar radiation viability detached Phytophthora infestans sporangia was assessed. A model estimate spore...
Background and aim: Soil structure is an important indicator of the quality soil, but detecting early signs soil degradation from difficult. Developing precise instruments able to diagnose quickly therefore critical improve management practices. Here, objective develop instrument analysing roughness surfaces resulting fracture cores, test instrument’s ability detect changes in cause by crop type tillage. We have designed constructed a 3D laser profilometer suitable for standard cores. The...
ABSTRACT Winter dormancy is a key process in the phenology of temperate perennials. The changing climate severely impacting its course leading to economic losses agriculture. A better understanding underlying mechanisms, as well genetic basis different responses, are necessary for development climate-resilient cultivars. This study aims provide an insight into winter red raspberry ( Rubus idaeus L). We report transcriptomic profiles during two cultivars with contrasting responses. cultivar...

Cereals are some of the most agriculturally important crops grown worldwide. Cereal aphids small sap-feeding insects that infest cereals and vector devastating cereal pathogens, principally yellow dwarf viruses, with severe infection reducing yields by 20-80%. Currently, farmers advised to apply insecticide if a single aphid is found within crop. However, this an oversimplification biology ecology vector-virus system: Each species can transmit range virus variable efficiency, intra-species...
Abstract Key message Shoot cultures from a population of British ash trees ( Fraxinus excelsior L.) were assessed for their ability to form roots in vitro and grow nursery conditions. Most the plants survived whether they had formed or not, but this was affected by systemic contaminant. This information will be valuable work aimed at overcoming die-back disease. Context Ash disease is killing Europe’s trees, with much breeding experimental underway help overcome it, including this. Aims...
