A new Deroceras species from North_Western spain (Gastropoda: Pulmonata: Agriolimacidae) Naturalis
Winter, A.J. de.
Deroceras ercinae spec. nov. is described from the Cantabrian Mountains, Spain. The characters used to define the subgenera of Deroceras are discussed. It is demonstrated that the present subdivision of this genus into subgenera is not based on synapomorphic characters.

A review of the genus Artocella van Achterberg with description of a new species from Spain Naturalis
Shaw, M.R..
A new species of the genus Artocella van Achterberg is described from Spain. On the basis of its substantial sexual dimorphisim, the differences between the two previously known species of this Turanian-Mediterranean genus, which had each been described from specimens of only one (and differing) sex, are reassessed.

A standardized description of European Sminthuridae (Collembola, Symphypleona), 3: description of seven species of Sminthurus, including four new to science Naturalis
Nayrolles, Pierre.
The following three species are redescribed: Sminthurus viridis (Linnaeus, 1758), Sminthurus nigromaculatus Tullberg, 1871, and Sminthurus multipunctatus Schäffer, 1896. Four new species are described from France and Spain: Sminthurus bourgeoisi n. sp., Sminthurus bozoulensis n. sp., Sminthurus leucomelanus n.sp.,and Sminthurus hispanicus n. sp. The importance of the ontogeny of chaetotaxy is stressed. Indeed, not all species acquire the secondary chaetotaxy in the same instar, and for these characters the most informative instar is not the adult but the third juvenile instar. The study of such characters involves the clustering of similar characters. A short discussion is given about this issue (selection of characters and clustering criteria).

Adaptations to hard substrates in Pennsylvanian productides (Brachiopoda) from the Cantabrian mountains (North-West Spain) Naturalis
Martínez Chacón, M.L.; Winkler Prins, C.P..
The Pennsylvanian deposits with carbonate platforms and reef structures from the Cantabrian Mountains are briefly described. The main portion of this paper is dedicated to the discussion of the adaptations of the Productidina from these Pennsylvanian formations of the Cantabrian Mountains to their life on hard substrates, comparing them with similar forms found elsewhere, notably in the Mississippian of northwest Europe and the Permian of Texas. In the systematic part, an indeterminate Plicatiferini is described as well as a new genus, Bruntonoconcha, and the new species Limbifera bruntoni, Parmephrix candemuelensis and Bruntonoconcha celadensis.

Agricultural trade liberalisation in the Doha Round: impacts on Spain AgEcon
Philippidis, George.
Whilst there is a growing literature of computable general equilibrium (CGE) studies examining the impacts of the current Doha Proposals, estimates for the EU are highly aggregated (i.e., EU15). Employing a detailed baseline scenario and a plausible Doha outcome, we examine the long run costs for the European Union, in particular focusing on Spain. Moreover, we implement recent CAP reforms through explicitly modelling of CAP mechanisms to provide greater credibility in assessing the long run asymmetric budgetary and welfare impacts on EU member states. Our estimates forecast resource substitution effects between Spanish agro-food sectors and resource shifts from agro-food activities into manufacturing and services production. In Spain, the impacts of...

Asymetric Price Transmission in the Spanish Lamb Sector AgEcon
Ben Kaabia, Monia; Gil, Jose Maria.
This paper aims to investigate the non-linear adjustments of prices between farm and retail prices in the lamb sector in Spain. The methodology used is based on the multivariate approach to specify and estimate a three-regime Threshold Autoregressive Model. Results indicate that in the long-run price transmission is perfect and any supply or demand shocks are fully transmitted along the marketing chain. In the short-run, price adjustments between the farm and the retail levels are asymmetric and are representative of a demand-pull transmission mechanism. On the other hand, retailers benefit from any shock, whether positive or negative, that affects supply or demand conditions.

Biodynamic agriculture shows steady global growth Organic Eprints
Paull, John.
New figures released by Demeter-International reveal the steady global growth of biodynamic agriculture. Certified biodynamic hectares are up 2% (from 144,497 to 147,495 hectares), biodynamic processors are up 5% (from 456 to 478), and biodynamic distributors are up 3% (from 185 to 190). The number of countries with Demeter-International certified biodynamic activity increased from 48 to 52. Croatia and Peru enter the list with newly reported biodynamic farms, and Bulgaria and Ukraine enter the list with new biodynamic distributors. There is considerable volatility in the statistics, with most countries reporting changes in the statistics for 2012 compared to the previous year. The three leading countries, based on biodynamic hectares, are Germany (with...

[Biostratigraphy and paleoecology of the Neogene micromammalian faunas from the Calatayud-Teruel Basin (Spain) / Freudenthal, M. (editor)]: Insectivora from the upper Aragonian and the lower Vallesian of the Daroca-Villafeliche area in the Calatayud-Teruel Basin (Spain) Naturalis
Jong, F. de.
In this study the insectivores from the Upper Aragonian and the Lower Vallesian of the Daroca-Villafeliche area in the Calatayud-Teruel Basin (Spain) are described and compared with related insectivore species from other European localities. The paleoecological significance of the insectivores is evaluated. The species described are: Galerix exilis, Galerix socialis, Desmanella crusafonti, Miosorex grivensis, and Crusafontina endemica. An attempt is made to separate G. exilis from G. socialis on the basis of size and morphology.

Bivalves from the Triassic-Jurassic transition in northern Spain (Asturias and western Basque-Cantabrian Basin) Ameghiniana
Márquez-Aliaga,Ana; Damborenea,Susana; Gómez,Juan José; Goy,Antonio.
Bivalve mollusks from the Triassic-Jurassic transition collected in eight localities in Asturias and the western Basque-Cantabrian Basin (Palencia province) are systematically revised. Preservation is poor at all localities. The dominant Rhaetian bivalves are Isocyprina concentrica (Moore) and Bakevellia (Bakevelloides) praecursor (Quenstedt). These species, together with Isocyprina cf. ewaldi (Bornemann), Pteromya cf. crowcombeia (Moore), Pseudoplacunopsis alpina (Winkler), and Modiolus? sp. (cf. minimus J. Sowerby), with a specimen of Arcestidae (?), belong to an assemblage similar to that found in the Westbury and Lilstock formations (Penarth Group) in the late Rhaetian of southern England. The most abundant Hettangian species is Isocyprina...

Brachiopods from the Valdeteja Formation (Pennsylvanian; Cantabrian Mountains, NW Spain) Naturalis
Martínez Chacón, M.L.; Winkler Prins, C.P..
After a short introduction on the lower Pennsylvanian (Bashkirian to lowermost Moscovian)Valdeteja Formation in its stratigraphical context, an overview of its brachiopod faunas is presented and their palaeoecological and palaeogeographic importance discussed. Two new genera of the Strophalosiidina, showing adaptations to a reef environment, are described. The genus Ovetina (type species O. truyolsi gen. et sp. nov.) is an aulostegid with a well developed ventral flange. Miroproductus (type species M. posadai gen. et sp. nov.) is an early richthofenioid, probably derived from an aulostegid such as Institina MUIR-WOOD & COOPER, 1960.

CAP Reform and the Mediterranean EU-Member States AgEcon
Borresch, Rene; Kavallari, Aikaterini; Schmitz, P. Michael.
In the previous years the Mediterranean Member States of the EU came across the Reform of the CAP and especially last year faced the second wave of the Reform for three typical Mediterranean products, namely cotton, olive oil and tobacco. In this paper a partial equilibrium model is used to simulate the impacts of decoupling, as a key point of the decided CAP Reform. The second wave of the Reform appears to be of crucial importance for the southern EU countries and although the producer's income is reduced, there are positive welfare effects.

Considerations on most Rugosa and the Dividocorallia from de Groot’s (1963) collection Naturalis
Fedorowski, J..
Rugose corals reinvestigated herein constitute the main part of the collection described by de Groot (1963). The taxonomy proposed herein differs in several instances from that accepted originally by de Groot. Some changes, such as Petalaxis for Lithostrotionella and Calophyllum instead of Polycoelia, were already introduced in de Groot’s unpublished catalogue. Others were introduced in order to match the recent advances in rugose coral systematics. Most systematic changes were based on new microstructural, diagenetic and hystero-ontogenetic studies. These are described in detail for individual species and briefly discussed in the concluding considerations. Trabecular microstructure of septa and its diagenetic alteration was documented for most species....

Co-operation and economic relationship as determinants for competitiveness in the food sector: the Spanish wheat to bread chain AgEcon
de Magistris, Tiziana; Gracia, Azucena.
The objective of the paper is to investigate the impact of co-operation amongst stakeholders of the food chain on enterprise competitiveness. The analysis focuses on the Spanish wheat to bread chain. A theoretical model is developed which covers the main components that define competitiveness (profitability, turnover, market share, customer loyalty and product quality), quality supply chain relationship (trust, commitment and satisfaction) and the main factors explaining supply chain relationship (i.e. quality and frequency of the communication, personal bounds, etc.). The Spanish wheat to bread supply chain has been chosen to empirically test the model. This sector is very fragmented all along the chain, with a high number of wheat farmers, millers and...

Co-operative Bank System: The Spanish Case AgEcon
Navarro, Amparo Melian.
In practically all European countries, co-operative credit societies have evolved towards a system which is comparable to other financial groups. This paper explores the recent evolution of Spanish credit co-operatives and especially rural savings banks. The creation of "Group Caja Rural" in 1989, has meant the greatest commitment to the integration of Spanish credit co-operatives in the face of the challenges of economic globalisation and the great changes in the national and international financial system. The running of this Group is through a vertebrate structure, in co-ordination and representation aspects as well as in operative functions.

Correlates between morphology, diet and foraging mode in the Ladder Snake Rhinechis scalaris (Schinz, 1822) Naturalis
Pleguezuelos, J.M.; Fernández-Cardenete, J.R.; Honrubia, S.; Feriche, M.; Villafranca, C..
In many vertebrates, foraging mode (active versus sit-and-wait) is tied to some traits of their natural history such as morphology, type of prey, rate of food acquisition, and survival rate. We explore the correlates between some morphological traits of a Mediterranean colubrid and its feeding ecology and the predation risk, by comparing data on teeth number, tail damage, and diet. A large sample (n = 368) of the Ladder Snake, Rhinechis scalaris is used. The species feeds almost exclusively on endotherms, mainly mammals (nearly 95% of the diet in mass), which set R. scalaris among the most stenophagous snakes in the western Palaearctic. There is also a high percentage of motionless prey in the diet (up to 50% in prey mass), such as nestling birds, mammals...

Do defaults matter? Willingness to pay to avoid GM food vis-à-vis organic and conventional food in Denmark, Great Britain and Spain AgEcon
Costa-Font, Montserrat; Tranter, Richard B.; Gil, Jose Maria; Jones, Philip J.; Gylling, Morten.
The introduction and communication of new technologies in the food industries has given rise in the past to some scientific uncertainty that hampers informed choice. Here we draw upon the case of Genetically Modified (GM) technology and, in particular, on different types of GM food, to investigate consumers’ behavioural reactions to GM food as well as their willingness to pay for avoiding GM food in three EU countries, Denmark, GB and Spain in 2007. Our unique contribution lies in that our empirical analysis concerns two food products containing different characteristics. In particular, we compare consumers’ reactions to cornflakes (to represent a processed food) and tomatoes (to represent a 'fresh' food) juxtaposed with GM and conventionally produced...
