L'Home part de la biosfera i objecte d'estudi de l'Ecologia
Durant 1'anv 1970 hom ha parlat i ha escrit molt, a tot el món, de protecció de la natura, de pol·lució, de 'l'explosió demogràfica' i també d'ecologia. Han estat organitzades reunions d'estudi i de pressió a tots els ...
Long-term recovery patterns and limited spillover of large predatory fish in a Mediterranean MPA
Based on 19 y of visual census data from the Medes Islands MPA (NW Mediterranean), this study analyzes the carrying capacity (K) and population recovery time of six species of fish strongly affected by harvesting pressure ...
Insights into Persistence Mechanisms of a Zoonotic Virus in Bat Colonies Using a Multispecies Metapopulation Model.
Rabies is a worldwide zoonosis resulting from Lyssavirus infection. In Europe, Eptesicus serotinus is the most frequently reported bat species infected with Lyssavirus, and thus considered to be the reservoir of European ...
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 ...
Bridges Between Soil Restoration, Land Management and Community Involvement in the Great Green Wall of Mauritania: A Preliminary Study
In the Sahel, land ownership is significantly influenced by the complexity of hierarchical, ethnic, and tribal aspects as well as communal, religious, and state rights. This complicates the development of large-scale ...
Gautieria trabutii (Gasteromycetes), nueva cita para la Peninsula Iberica
Se describe y comenta un raro e interesante hongo hipogeo, Gautieria trabutii (Chat.) Pat. (Gasteromycetes), recolectado por primera vez en la Península Ibérica.
Remote Sensing for Precision Agriculture: Sentinel-2 Improved Features and Applications
The use of satellites to monitor crops and support their management is gathering increasing attention. The improved temporal, spatial, and spectral resolution of the European Space Agency (ESA) launched Sentinel-2 A + B ...
Antimitotic and hormone effects on green diplohaploid plant production through anther culture on Mediterranean japonica rice
Rice double haploid (DH) plants are produced mainly through anther culture. In order to improve the anther culture protocol, microspores of two japonica rice genotypes (NRVC980385 and H28) were subjected to three growth ...
The Response of Arundo donax L. (C3) and Panicum virgatum (C4) to different stresses
In this work, two perennial rhizomatous grasses (Arundo donax L. (giant reed; C3) and Panicum virgatum L. (switchgrass; C4)) considered as promising energy crops have been subjected to four different types of stress in two ...
Habitat-based biodiversity responses to macroclimate and edaphic factors in European fen ecosystems
Understanding large-scale drivers of biodiversity in palustrine wetlands is challenging due to the combined effects of macroclimate and local edaphic conditions. In boreal and temperate fen ecosystems, the influence of ...
The Andean Biotic Index (ABI): revised tolerance to pollution values for macroinvertebrate families and index performance evaluation.
Score-based biotic indices are widely used to evaluate the water quality of streams and rivers. Few adaptations of these indices have been done for South America because there is a lack of knowledge on mac-roinvertebrate ...
La restauración ecológica aplicada a la minería a cielo abierto en Cataluña
En la minería a cielo abierto, la revegetación es el objetivo principal de las tareas de restauración ecológica y puede evaluarse desde diferentes enfoques. El aspecto paisajístico ha sido hasta la fecha el más ampliamente ...
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 ...
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 ...
Estudio ecológico de las comunidades nitrófilas mediolitorales
Algunas comunidades de la costa catalana están dominadas por especies nitrófilas del orden Ulvales. El estudio de su composición específica, su producción y su estructura espacial (en base a la diversidad y a coeficientes ...
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 ...
Leaders-cheaters in male group cooperation: differences in nonverbal communication and genetic factors
Here we report on the results of an experimental study investigating "who?" emerges as a leader in the context of male group cooperation and "how?" they do that. The study was designed based on the iterated Public Goods ...

Comparative Salt-Stress Responses in Salt-Tolerant (Vikinga)and Salt-Sensitive (Regalona) Quinoa Varieties. Physiological, Anatomical and Biochemical Perspectives
Soil salinization is an important stress factor that limits plant growth and yield. Increased salinization is projected to affect more than 50% of all arable land by 2050. In addition, the growing demand for food, together ...
