A novel approach to analysing the regimes of temporary streams in relation to their controls on the composition and structure of aquatic biota
Temporary streams are those water courses that undergo the recurrent cessation of flow or the complete drying of their channel. The structure and composition of biological communities in temporary stream reaches are strongly ...
El elemento fitogeografico eurosiberiano en las sierras litorales catalanas
La Biogeografia, lo mismo que la Biocenolcgía, debe estudiar conjuntos de organismos de extraordinaria complejidad. En realidad, cada especie y cada entidad taxonómica inferior (subspecie, variedad) se comporta de modo ...
Descripción de una especie nueva de Melanips Walker (Hymenoptera: Figitidae), primer registro del género para la región neotropicaL
A new species of Melanips Walker (Hymenoptera: Figitidae) from Mexico, Melanips lomeyva sp. nov. is described. This species represents the first record of the genus Melanips from Mexico and to the Neotropical region. ...
Active ecological restoration of cold-water corals: techniques, challenges, costs and future directions
Cold-water coral (CWC) habitats dwell on continental shelves, slopes, seamounts, and ridge systems around the world's oceans from 50 to 4000 m depth, providing heterogeneous habitats which support a myriad of associated ...
La qualitat de les aigües del riu Muga: Dades físiques, químiques, i biològiques
El riu Muga és estretament identificat amb l'Alt Empordà. Neix en el seu punt més extrem de ponent, el travessa en tota la seva extensió i mor quan se li acaba el país a la badia de Roses. Juga un paper cabdal en el ...
A Cadaver Based Comparison of Two Elastic Tension Proximal Interphalangeal Joint (PIPJ) Extension Orthoses with Focus on Force Generation and Pressure Distribution
Proximal interphalangeal joint flexion contracture is a frequent condition in hand therapy. Clinicians most frequently apply orthosis management for conservative treatment. Orthoses should apply forces for long periods of ...

Long-term monitoring of temperate macroalgal assemblages inside and outside a No take marine reserve
Macroalgal communities have an essential role in the shallow benthic habitats of temperate seas, where changes in their composition can resonate through entire coastal ecosystems. As all major ecosystems on Earth, algal ...
A novel aspect of essential oils: Coating seeds with thyme essential oil induces drought resistance in wheat
Coating seeds with biostimulants is among the promising approaches in crop production to increase crop tolerance to drought stress. In this study, we evaluated the potential of coating durum wheat seeds of the cultivar ...
Evidence that the Montseny mountains are still a good climatic refugium for the southernmost silver fir forest on the Iberian Peninsula
Many European temperate tree species reach their southern distribution limits in the Mediterranean region, and ongoing climate change will further restrict their climatic niche in this area. In this study, we investigated ...
Low Dynamics, High Longevity and Persistence of Sessile Structural Species Dwelling on Mediterranean Coralligenous Outcrops
There is still limited understanding of the processes underlying benthic species dynamics in marine coastal habitats, which are of disproportionate importance in terms of productivity and biodiversity. The life-history ...
Benthos of Spanish lakes and reservoirs
A summary of the results from the study of benthos of lakes and reservoirs in Spain is provided, with a list of the species found to date. Spanish natural lakes are smaller than European lakes; the largest is Lake Sanabria, ...
Sobre la variabilitat de Pedicularis pyrenaica i la presència de Pedicularis mixta (Orobanchaceae) als Pirineus orientals
We present some remarks on the morphological characterization and the distribution areas of <i>Pedicularis pyrenaica</i> and <i>P. mixta</i>, both endemic to the Pyrenean and Cantabrian ranges. It should be noted that an ...
Mas sobre el Genero Dianthus L. (Caryophyllaceae)
Nos referiremos en primer lugar a D. multiaffinis Pau (Bol. Soc. Esp. Hist. Nat. 21:142. 1921). Descrito de la Sierra de Espadan, pocos han sido los autores posteriores que han tenido en cuenta este nombre. Únicamente, O. ...
El mostratge fitocenològic a Catalunya
irregular. With reference to the 10 km UTM network, the number of relevés per cell ranges between 0 and 527, with a mean of 36, the most exhaustively prospected areas lying in the Pyrenean range. On the other hand, 44 cells ...

Finite mixture model: decompose a surface into "n" subadjacent gaussian bells. A Mathematica 7 script
The script works with Mathematica (version 7 or latest) however Laplacian filter and the finite mixture can be easily implement with any other mathematical software.
Plasticity in secondary sexual characteristics in male freshwater blennies (Salaria fluviatilis)
Alternative reproductive tactics (ARTs) driven by environmental factors are common among fish. However, the flexibility of fish to adopt distinct tactics in response to the characteristics of their environment has received ...
Vertical patterns of metabolism in three contrasting stratified lakes
Recent advances in open water measurements suggest significant temporal and spatial variability of gross primary production (GPP), net ecosystem production (NEP), and respiration (R) with implications for understanding ...
