Cost and benefits for the segregation of GM and non-GM compound feed AgEcon
Gryson, N.; Eeckhout, M.; Neijens, T..
Measures are being developed and implemented enabling the co-existence of conventional, genetically modified (GM) and organic cropping systems. In order to segregate GM from conventional crops in the entire supply chain, a food or feed company has to reorganise its production. This may involve for dedication of the production line to non-GM, or production can be organised on the same plant, using spatial or temporal segregation. In practice, only the latter method is used in the feed industry, as no investments in new machinery are necessary in the case. The segregation and identity preservation of GM and non-GM crops has to be well organised. An important tools used to proof the identity of the imported raw materials is the batch or product declaration...

Cost of GMO-related co-existence and traceability systems in food production in Germany AgEcon
Menrad, Klaus; Gabriel, Andreas; Zapilko, Marina.
In contrast to the increasing use of GM plants in world-wide agriculture, the acceptance of GM food is still low in the European Union (EU). In order to ensure freedom of choice for consumers and users of GM and non-GM products, GM food and feed products have to be labeled in case a tolerance threshold of 0.9 % is exceeded for EU authorized GMOs. This paper aims to quantify the cost of traceability and co-existence systems for GM food from the seed to the food level for sugar, wheat starch and rapeseed oil for human consumption in Germany respecting the 0.9 % threshold for labelling of GM food. The cost calculation for traceability and co-existence measures follows the principle of aggregating all incurred cost on the different levels of the value chain...

Diet of two syntopic species of Crenuchidae (Ostariophysi: Characiformes) in an Amazonian rocky stream Biota Neotropica
Fernandes,Suzanne; Leitão,Rafael Pereira; Dary,Eurizângela Pereira; Guerreiro,Ana Isabel Camacho; Zuanon,Jansen; Bührnheim,Cristina Motta.
Abstract This study assessed the diet of two poorly known syntopic fish species of the family Crenuchidae, Characidium aff. declivirostre and Leptocharacidium omospilus, in a Presidente Figueiredo´ rocky stream, Amazonas, Brazil. The stomach contents were analyzed and their Frequency of Occurrence (FO %) and Relative Volume (Vol %) were combined in a Feeding Index (IAi). We examined 20 individuals of C. aff. declivirostre and 23 of L. omospilus. The Morisita-Horn Index was used to estimate the overlap between the diets of these species. Immature insects were the most valuable items consumed by both fish species. The diet of C. aff. declivirostre was mainly composed of larvae and pupae of Chironomidae, while L. omospilus predominantly consumed larvae of...

Governing the Co-existence of GM Crops: Ex-Ante Regulation and Ex-Post Liability under Uncertainty and Irreversibility AgEcon
Beckmann, Volker; Soregaroli, Claudio; Wesseler, Justus.
The future institutional environment for the co-existence of genetically modified (GM) crops, conventional crops and organic crops in Europe combines measures of ex-ante regulation and ex-post liability rules. Against this background we ask the following two questions: How does ex-ante regulation and ex-post liability under irreversibility and uncertainty affect the adoption of GM crops? What are the implications for regional agglomeration of GM and non-GM crops? Ex-ante regulations and ex-post liabilities for using GM crops will induce additional costs. These costs are modelled in a classical way. The model is advanced by including irreversibility and uncertainty and taking into account transaction costs of negotiating possible solutions with neighbouring...

On the Coexistence of Spot and Contract Markets: a Delivery Requirement Explanation AgEcon
Hendrikse, George W.J..
A model is presented in which spot and contract market exchange co-exist. A contract consists of a delivery requirement between an upstream and a downstream party. Contract formation determines to a certain extent the probability distribution of the spot market price. This contract formation externality entails the removal of high reservation price buyers and various sellers from the spot market. The first effect decreases the expected spot market price when the number of contracts is small, whereas the decrease in the number of sellers and additional residual contract demand increase the expected spot market price beyond a certain number of contracts. It implies an endogenous upper bound on the number of contracts. Contract prices are positively related...

Pharmaceutical and Industrial Traits in Genetically Modified Crops: Co-existence with Conventional Agriculture AgEcon
Moschini, GianCarlo.
This paper discusses the implications of using genetically modified crops to biomanufacture pharmaceuticals and industrial compounds from the perspective of their co-existence with conventional agriculture. Such plant-made pharmaceuticals and plant-made industrial products rely on exciting scientific and technological breakthroughs and promise new opportunities for the agricultural sector, but they also entail novel risks. The management of the externalities and of the possible unintended economic effects that arise in this context is critical and poses difficult questions for regulators.

The epiphytic orchids Ionopsis utricularioides and Psygmorchis pusilla associate with different Ceratobasidium lineages at Valle del Cauca, Colombia Acta Botanica
Valadares,Rafael Borges da Silva; Otero,Joel Tupac; Pereira,Marlon Corrêa; Cardoso,Elke Jurandy Bran Nogueira.
In Orchidaceae, association with symbiotic fungi is required for seed germination and seedling development, thereby being the main energy source during the first steps of germination. Colombia is one of the countries with the greatest biodiversity of orchids, with an estimated 3,200 species, but few studies on orchid mycorrhiza have been conducted. In our study, we isolated and sequenced the internal transcribed spacer rDNA region of fungi from two co-occurring Colombian epiphytic orchids, I. utricularioides and P. pusilla, both belonging to the subtribe Oncidiinae. All sequences were recognized as belonging to the genus Ceratobasidium, known to be a common orchid mycorrhizal fungus in both tropical and temperate orchids. One sequence was 100% similar to...
