  • CRISPR is coming to agriculture — with big implications for food, farmers, consumers and nature

    Gene editing offers dramatic advances in speed, scope and scale of genetic improvement. It also offers an opportunity for more nuanced GMO governance. Very few technologies truly merit the epithet “game changer” — but a new genetic engineering tool known as CRISPR-Cas9 is one of them. Since we first developed the ability to alter the genetic material inside a plant or animal in ...

  • For lively fish in the water Oil-free generation of oxygen at fish farm - Case Study

    For 30 years, trout have been cultivated at the Winkelmann farm in Wietzendorf (Lower Saxony), southeast of the city of Soltau. What started out as a hobby ultimately became a business. Since then, the main goal has been the preparation of fish eggs, caviar (roe). The female trout are brought up in concrete semi-circulating basins and slaughtered after 26 to 29 months as salmon trout. The annual ...

  • Fishing for a Solution

    As writer Rowan Jacobsen explores in our recent feature “Has Meat Met Its Match?,” animal agriculture’s hefty environmental footprint is creating interest in exploring ways to meet humans’ growing appetite for animal protein that extend beyond beef, chicken and pork. In some places, that ...

  • Effects of the herbicide imazapyr on juvenile Oregon spotted frogs

    Conflict between native amphibians and aquatic weed management in the Pacific Northwest is rarely recognized because most native stillwater‐breeding amphibian species move upland during summer, when herbicide application to control weeds in aquatic habitats typically occurs. However, aquatic weed management may pose a risk for aquatic species present in wetlands through the summer, such as the ...

  • Intellectual property and Freedom To Operate in the flax breeding world: Canada in the global context

    Through one-on-one in-depth interviews of Canadian public sector flax breeders, this study explores issues around Intellectual Property (IP) and Freedom To Operate (FTP) in flax breeding from a Canadian perspective. The results are supported by a scan of flax breeding efforts worldwide, an in-depth patent analysis (using Patent Lens and the US Patent and Trademark Office (USPTO) databases) and a ...

  • A spatially and temporally explicit risk assessment for salmon from a prey base exposed to agricultural insecticides

    This risk assessment applied a framework for determining probable co‐occurrence of juvenile spring Chinook salmon (Oncorhynchus tshawytscha) with agricultural pesticides in the Willamette Basin, Oregon (Teply et al. this issue) to characterize risk to the threatened population. The assessment accounted for spatial and temporal distribution of 6 acetylcholinesterase‐inhibiting insecticides in ...

  • A spatially and temporally explicit model for determining the exposure of juvenile salmon to agricultural pesticides in freshwater

    In this paper, we present a novel approach for determining the probable co‐occurrence of juvenile salmon or steelhead with agricultural pesticides and apply it to spring Chinook (Oncorhynchus tshawytscha) salmon in the Willamette Basin, Oregon. We adapted a published exposure analysis framework by explicitly considering fish migration among habitat units and assuming that habitat use is ...

  • Freshwater ecosystems

    Freshwater ecosystems in Europe are rich in biodiversity and provide essential ecosystem services to humans Europe's freshwater ecosystems range from rivers, flood plains, lakes and ponds, marshes and peatlands, to man-made water bodies such as canals and reservoirs (EC, 2007a; EC, 2007b). They encompass a broad variety of wetlands. These different systems also interact with groundwater. ...

  • Outcrossing in early-stage spring wheat breeder seed development

    Outcrossing (OC) during the initial stages of spring wheat (Triticum aestivum L.) breeder seed development ('head-rowing') may lead to off-types appearing in later generations of pedigreed seed. The objective of this research project was to measure OC in a simulated short (1.3 m) breeder row nursery of spring wheat. Rows of four cultivars known to differ in OC potential were grown at up to 12 ...

  • Spanish Fish Farmer chooses LIT

    Spanish fish farmer chooses LIT-UV Isidro de la Cal is a Spanish group of companies that are active in the fish industry. The company controls the entire process of farming, capturing, processing and finally selling the end product to the stores where consumers buy the various fish products. The fish that is processed by Isidro de la Cal comes from various national, mainly Galician, and ...

  • Genetic diversity and relationships among 177 public sunflower inbred lines assessed by trap markers

    This study investigated the genetic diversity and relationships among the 177 public sunflower (Helianthus annuus L.) inbred lines developed and released by USDA-ARS from the 1970s to 2005 using the target region amplification polymorphism (TRAP) marker technique. Twelve primer combinations generated a total of 230 polymorphic markers that could discriminate each of these lines, suggesting that ...

  • Population Genetic Structure of Astyanax scabripinnis (Teleostei, Characidae) from an Urban Stream

    Despite the great anthropogenic interference on urban streams, information is still scarce about the genetic variability and structure of native fish populations inhabiting such streams. In the present study, random amplified polymorphic DNA (RAPD) markers were used to analyze genetic variability and structure of populations assigned to the Neotropical fish species Astyanax scabripinnis from an ...

  • Sustainable agriculture and sustainability of Indian agriculture in the context of globalisation

    There is a growing realisation of the importance of sustainable agriculture across the globe. This awareness has become the main focus of global debate as a result of degradation of natural resources and environment. There is a growing demand for eco-friendly agricultural commodities in the international market. Here an attempt is made to examine the context and meaning of the term ...
