Silver Clusters of Five Atoms as Highly Selective Antitumoral Agents Through Irreversible Oxidation of Thiols

Vanesa Porto, David Buceta, Blanca Domínguez, Carmen Carneiro, more

Advanced Functional Materials > 32 > 29 > n/a - n/a

Low atomicity clusters present properties dependent on the size, due to the quantum confinement, with well‐defined electronic structures and high stability. Here it is shown that Ag₅ clusters catalyze the complete oxidation of sulfur to S⁺⁶. Ag₅ catalytic activity increases with different oxidant species in the order O₂ ≪ H₂O₂ < OH•. Selective oxidation of thiols on the cysteine residues of glutathione...

The concurrent assessment of agronomic, ecological and environmental variables enables better choice of agroecological service crop termination management

David Navarro‐Miró, José M. Blanco‐Moreno, Corrado Ciaccia, Elena Testani, more

Journal of Applied Ecology > 59 > 4 > 1026 - 1037

Although organic farming was originally promoted as an alternative farming system to address agronomic, environmental and ecological issues, its conventionalisation has led to an intensification and specialisation of production. In the light of this, several studies have questioned the environmental benefits of organic farming as well as its agronomic viability. Thus, there is a need to improve...

Reduced crop sowing density improves performance of rare arable weed species more effectively than reduced fertilisation

Roser Rotchés‐Ribalta, José M. Blanco‐Moreno, Francesc Xavier Sans

Weed Research > 60 > 4 > 269 - 277

Characteristic arable weed species of dryland cereal fields have undergone significant declines, due to agricultural intensification, to the point that some of them are considered rare. Crop edges host higher abundances of arable weed species, therefore they may act as a refuge for the conservation of these rare arable species. Using mesocosms, we experimentally tested how conditions at field edges...

Agroecological service crops managed with roller crimper reduce weed density and weed species richness in organic vegetable systems across Europe

David Navarro-Miró, José M. Blanco-Moreno, Corrado Ciaccia, Lourdes Chamorro, more

Agronomy for Sustainable Development > 2019 > 39 > 6 > 1-13

Agroecological service crops are introduced into the vegetable crop rotation to provide agroecosystem services, and are a key strategy for weed management in organic systems. Organic farmers across Europe usually terminate these crops before cultivation of the subsequent cash crop, using them as green manure. Recently, the in-line tillage-roller crimper has attracted interest across Europe. It allows...

Patterns of flower visitor abundance and fruit set in a highly intensified cereal cropping system in a Mediterranean landscape

Marian Mendoza-García, José M. Blanco-Moreno, Lourdes Chamorro, Laura José-María, more

Agriculture, Ecosystems & Environment > 2018 > 254 > C > 255-263

In intensive agricultural landscapes, decreased pollinator numbers have often been attributed to the loss of natural habitats. However, several studies show that certain mass flowering crops, such as oilseed rape (OSR), can alter the pattern of pollinator abundance at a field and landscape level. These studies have focused mainly on bees; information about the effect of OSR crops on other taxa is...

A 2-set-up Routley-Meyer Semantics for the 4-valued Relevant Logic E4

Gemma Robles, Sandra M. López, José M. Blanco, Marcos M. Recio, more

Bulletin of the Section of Logic > 2016 > 45 > 2

The logic BN4 can be considered as the 4-valued logic of the relevant conditional and the logic E4, as the 4-valued logic of (relevant) entailment. The aim of this paper is to endow E4 with a 2-set-up Routley-Meyer semantics. It is proved that E4 is strongly sound and complete w.r.t. this semantics.

Relational semantics for the 4-valued relevant logics BN4 and E4

Gemma Robles, José M. Blanco, Sandra M. López, Jesús R. Paradela, more

Logic and Logical Philosophy > 2016 > 25 > 2 > 173-201

The logic BN4 was defined by R.T. Brady in 1982. It can be considered as the 4-valued logic of the relevant conditional. E4 is a variant of BN4 that can be considered as the 4-valued logic of (relevant) entailment. The aim of this paper is to define reduced general Routley-Meyer semantics for BN4 and E4. It is proved that BN4 and E4 are strongly sound and complete w.r.t. their respective semantics.

Herbivores, saprovores and natural enemies respond differently to within-field plant characteristics of wheat fields

Berta Caballero-López, José M. Blanco-Moreno, Juli Pujade-Villar, Daniel Ventura, more

Journal of Insect Conservation > 2016 > 20 > 3 > 467-476

Understanding ecosystem functioning in a farmland context by considering the variety of ecological strategies employed by arthropods is a core challenge in ecology and conservation science. We adopted a functional approach in an assessment of the relationship between three functional plant groups (grasses, broad-leaves and legumes) and the arthropod community in winter wheat fields in a Mediterranean...

Herbicide impact on the growth and reproduction of characteristic and rare arable weeds of winter cereal fields

Roser Rotchés-Ribalta, Céline Boutin, José M. Blanco-Moreno, David Carpenter, more

Ecotoxicology > 2015 > 24 > 5 > 991-1003

The decline of arable species characteristic of winter cereal fields has often been attributed to different factors related to agricultural intensification but most importantly to herbicide use. Herbicide phytotoxicity is most frequently assessed using short-term endpoints, primarily aboveground biomass. However, short-term sensitivity is usually not sufficient to detect actual effects because plants...

Long-term feasibility of reduced tillage in organic farming

Laura Armengot, Alfred Berner, José M. Blanco-Moreno, Paul Mäder, more

Agronomy for Sustainable Development > 2015 > 35 > 1 > 339-346

Agricultural practices such as soil tillage emit greenhouse gases such as CO₂ and N₂O. As a consequence, reducing the tillage could both reduce greenhouse emissions and improve soil quality. In Europe about 25 % of arable land is managed under reduced tillage and no tillage, mainly using herbicides to get rid of weeds. Therefore, a major drawback for organic farmers is that the lack of herbicide and...

Reduced seed predation after invasion supports enemy release in a broad biogeographical survey

Eva Castells, Maria Morante, José M. Blanco-Moreno, F. Xavier Sans, more

Oecologia > 2013 > 173 > 4 > 1397-1409

The Enemy Release (ER) hypothesis predicts an increase in the plant invasive capacity after being released from their associated herbivores or pathogens in their area of origin. Despite the large number of studies on biological invasions addressing this hypothesis, tests evaluating changes in herbivory on native and introduced populations and their effects on plant reproductive potential at a biogeographical...

Shrub–tree interactions and environmental changes drive treeline dynamics in the Subarctic

Oriol Grau, Josep M. Ninot, José M. Blanco‐Moreno, Richard S. P. van Logtestijn, more

Oikos > 121 > 10 > 1680 - 1690

Treelines have drawn persistent research interest as they can respond markedly to climate. However, the mechanisms that determine tree seedling recruitment and the response of the forest‐tundra ecotone to environmental changes remain poorly understood. We hypothesise that treeline tree seedling performance depends on the interplay between climatic and soil nutritional changes and facilitative and...

Weeds, aphids, and specialist parasitoids and predators benefit differently from organic and conventional cropping of winter cereals

Berta Caballero-López, José M. Blanco-Moreno, Nicolás Pérez-Hidalgo, José M. Michelena-Saval, more

Journal of Pest Science > 2012 > 85 > 1 > 81-88

The aphid–natural enemy interaction in winter wheat fields constitutes a complex system that has been frequently studied because of its implication for biological control. However, not all of the aphids living in cereal fields are crop pests, as there are also aphids living on weeds that may serve as alternative hosts or prey for aphid parasitoids or predators. In this context, a concomitant survey...

Factors affecting plant species richness in field boundaries in the Mediterranean region

Montserrat Bassa, Lourdes Chamorro, Laura José-María, José M. Blanco-Moreno, more

Biodiversity and Conservation > 2012 > 21 > 4 > 1101-1114

Field boundaries are expected to support the maintenance of biodiversity in agroecosystems, since they provide the habitat for a range of plant species. However, plant diversity in field boundaries has decreased substantially in recent decades. This pattern is generally linked with the intensification of agricultural land use at field and landscape level. Therefore, we aimed to test the effect of...

How does agricultural intensification modulate changes in plant community composition?

Laura José-María, José M. Blanco-Moreno, Laura Armengot, F. Xavier Sans

Agriculture, Ecosystems and Environment > 2011 > 145 > 1 > 77-84

Agricultural intensification, at local and landscape scales, has caused a decrease in plant diversity and changes in species composition in cereal fields. To better understand the role of landscape complexity and farming systems in shaping plant assemblages, it is of interest to focus on functional traits rather than on floristic composition, which may help to highlight trends in vegetation patterns...

Landscape and land-use effects on weed flora in Mediterranean cereal fields

Laura Armengot, Laura José-María, José M. Blanco-Moreno, Albert Romero-Puente, more

Agriculture, Ecosystems and Environment > 2011 > 142 > 3-4 > 311-317

Land-use intensity and landscape complexity could potentially affect weed flora of agroecosystems, by means of changes in species richness and composition. However, previous results indicate diverging patterns. This paper evaluates the relative importance of both factors on weed species richness and weed community composition within cereal fields in Catalonia (NE Spain). The percentage of arable land...

A novel index of land use intensity for organic and conventional farming of Mediterranean cereal fields

Laura Armengot, Laura José-María, José M. Blanco-Moreno, Montserrat Bassa, more

Agronomy for Sustainable Development > 2011 > 31 > 4 > 699-707

The conservation of biodiversity in agro-ecosystems is closely related to land use. Intensive land use is considered to be a major cause of biodiversity loss. Most studies addressing the effect of land use intensity on biodiversity have compared organic and conventional systems. However, little is known about the heterogeneity of the management intensity within each farming system. We hypothesise...
