Cartografía diacrónica: estabilidad y cambios en la vegetación de Rasos de Peguera (Prepirineos Orientales), 1956-2014. Actas XI Coloquio de Botánica pirenaicocantábrica
We analyse here the changes occurring in the vegetation of Rasos de Peguera Massif (2,057 m a.s.l., Eastern Pyrenees) in the period 1956-2014, by means of diachronic cartography. Our study includes a protected area (the ...
Physiological effects of the induction of resistance by compost or Trichoderma asperellum strain T34 against Botrytis cinerea in tomato
Certain types of compost used as growth media can induce resistance to foliar pathogens in above-ground parts of a plant. The induction of resistance can sometimes be associated with growth impairment and yield reduction. ...

Leaf Size modulation by cytokinins in sesame plants
Phytohormones play important roles in controlling leaf size and in the modulation of various stress responses, including drought. In this study, hormone profiling analyses by ultra high-performance liquid chromatography ...
The importance of intraespeciphic variation in the taxonomy of marine nematodes: The case of Terschellingia longispiculata Wieser & Hopper 1967 (Nematoda, Linhomoeidae)
In the presentstudy, the priority of taxonomic characters of cephalic region of Terschellingialongispiculata over those of the tail and reproductive system is discussed.Four morphological varieties of the species are ...
Phanacis urospermi (Kieffer, 1901) (Hymenoptera, Cynipidae)- an interestin reord from Malta
The only Cynipidae so far recorded from Malta is Diplolepis eglanteriae (Hartig, 1840) which induces smooth pea-like galls on Rosa sempervirens L. (Mifsud, 2016). Recently, one of us (MZ) reared a species of Cynipidae from ...
Enhanced Botrytis cinerea resistance of Arabidopsis plants grown in compost may be explained by increased expression of defense-related genes, as revealed by microarray analysis
Composts are the products obtained after the aerobic degradation of different types of organic matter waste and can be used as substrates or substrate/soil amendments for plant cultivation. There is a small but increasing ...
Interaction of Both Positive and Negative Daily-Life Experiences with FKBP5 Haplotype on Psychosis Risk.
Background: There is limited research on the interaction of both positive and negative daily-life environments with stress-related genetic variants on psychotic experiences (PEs) and negative affect (NA) across the extended ...
Streamflow reduction induces early parental care in Salaria fluviatilis (Asso, 1801) males.
This study investigated the effect of hydrological stress (streamflow reduction) on the reproductive and nesting behaviour of freshwater blenny (Salaria fluviatilis) males in a Mediterranean-type stream in NE Spain (a ...
Algunos datos sobre las comunidades vegetales de la Fageda de Jorda (Olot)
A pocos kilómetros al este de Olot, entre la Costa de Pujou y el Puig de Sant Jordi de Sa Cot, el llano está cubierto en gran parte por hayedos frondosos. Ellos han merecido al paraje el nombre de Fageda de Jordá, al cual ...
A trait-based approach reveals the feeding selectivity of a small endangered Mediterranean fish
Functional traits are growing in popularity in modern ecology, but feeding studies remain primarily rooted in a taxonomic-based perspective. However, consumers do not have any reason to select their prey using a taxonomic ...
Aplicació de la cibernètica a l'estudi de sistemes biològics al nivell de l'ecosistema

Agronomical and analytical trait data assessed in a set of quinoa genotypes growing in the UAE under different irrigation salinity conditions
The importance of quinoa has been emphasized considerably in the recent decades, as a highly nutritional crop seed that is tolerant to salinity and amenable to arid agronomical conditions. The focus of this paper is to ...
A mediterranean japonica rice (Oryza sativa) cultivar improvement through anther culture.
Certified seed producers systematically select and propagate registered varieties year after year in order to maintain their uniformity and the original registered cultivar traits. However, natural mutations, spontaneous ...
Fungal biodiversity mediates the effects of drying on freshwater ecosystem functioning
Investigating the influence of biodiversity on ecosystem functioning over environmental gradients is needed to anticipate ecosystem responses to global change. However, our understanding of the functional role of freshwater ...

Improving water quality does not guarantee fish health: Effects of ammonia pollution on the behaviour of wild-caught pre-exposed fish.
Ammonia is a pollutant frequently found in aquatic ecosystems. In fish, ammonia can cause physical damage, alter its behaviour, and even cause death. Exposure to ammonia also increases fish physiological stress, which can ...
