LandTrendr smoothed spectral profiles enhance woody encroachment monitoring
(Elsevier, 2021)Secondary succession (SS) is one of the main consequences of the abandonment of agricultural and forestry practices in rural areas, causing -among other processes- woody encroachment on former pastures and croplands. In ... -
Les landes, torberes i mulleres de l'Alta Ribagorça
(Institut Botànic de Barcelona, 1983)S'estudien fitosociològicament les comunitats dominades per ciperacles i ericàcies que constitueixen les landes i aiguamolls de les rodalies de l'Hospital de Viella (Alta Ribagorça). Es descriuen per primera vegada dues ... -
Light as a source of information in ecosystems
(American Association for the Advancement of Science, 2017) -
Long-term effect of different tillage systems on the emergence and demography of Bromus diandrus in rainfed cereal fields
(European Weed Research Society, 2016)The adoption of no-tillage systems in semi-arid cereal fields in northern Europe has resulted in difficulties in controlling Bromus diandrus. However, in some fields, lower densities are observed in continuous long-term ... -
Management and site effects on carbon balances of European mountain meadows and rangelands
(Boreal Environment Research Publishing Board, 2015-11-20)We studied carbon balances and carbon stocks of mountain rangelands and meadows in a network of 8 eddy covariance sites and 14 sites with biomass data in Europe. Net ecosystem exchange of pastures and extensively managed ... -
Management of herbicide resistant corn poppy (Papaver rhoeas) under different tillage systems does not change the frequency of resistant plants
(Weed Science Society of America, 2018-07-05)Corn poppy (Papaver rhoeas L.) is the most widespread broadleaf weed species infesting winter cereals in Europe. Biotypes that are resistant to both 2,4-D and tribenuron-methyl, an acetolactate synthase (ALS)-inhibitor, ... -
Management Options for Multiple Herbicide–Resistant Corn Poppy (Papaver rhoeas) in Spain
(Weed Science Society of America, 2017)Corn poppy is the most widespread broadleaf weed infesting winter cereals in Europe. Biotypes that are resistant (R) to both 2,4-D and tribenuron-methyl have evolved in recent decades, thus complicating their chemical ... -
Mapping cynodon dactylon infesting cover crops with an automatic decision tree-OBIA procedure and UAV imagery for precision viticulture
(MDPI, 2019-12-21)The establishment and management of cover crops are common practices widely used in irrigated viticulture around the world, as they bring great benefits not only to protect and improve the soil, but also to control vine ... -
Maximizing the information obtained from chamber-based greenhouse gas exchange measurements in remote areas
(Elsevier, 2018)Measurements of greenhouse gas (GHG) fluxes, particularly methane (CH4) and nitrous oxide (N2O) in mountain ecosystems are scarce due to the complexity and unpredictable behavior of these gases, in addition to the remoteness ... -
May the inclusion of a legume crop change weed composition in cereal fields? Example of Sainfoin in Aragon (Spain)
(MDPI, 2019-03-14)Onobrychis viciifolia (Scop.) (sainfoin) is promoted in the Spanish Aragón region through the Agro-Environmental Schemes (AES) since 2007 with the aim of enhancing biodiversity. Also, in other countries, the interest in ... -
Mobile terrestrial laser scanner applications in precision fruticulture/ horticulture and tools to extract information from canopy point clouds
(Springer Science+Business Media, 2017-01-01)LiDAR sensors are widely used in many areas and, in recent years, that includes agricultural tasks. In this work, a self-developed mobile terrestrial laser scanner based on a 2D light detection and ranging (LiDAR) sensor ... -
Modeling emergence of sterile oat (Avena sterilis ssp. ludoviciana) under semiarid conditions
(Cambridge University Press, 2021)Winter wild oat [Avena sterilisssp. ludoviciana (Durieu) Gillet & Magne; referred to as A. sterilis here] is one of the major weed species of the Avena genus, given its high competitive ability to infest cereal crops ... -
Modeling moisture content in shrubs to predict fire risk in Catalonia (Spain)
(Elsevier, 2003)We measured the moisture content in small branches and leaves of Cistus monspeliensis in four Mediterranean locations of Catalonia (Spain), from 1998 to 2000. The moisture of the measured fraction is also known as live ... -
Modeling the emergence of North African Knapweed (Centaurea diluta), an increasingly troublesome weed in Spain
(Cambridge University Press, 2020)North African knapweed (Centaurea diluta Aiton) is an annual weed that is widespread in southern Spain and is of increasing concern in dryland cropping systems. Despite its expanding range in Spain, there is limited ... -
Modeling the emergence of three arable bedstraw (Galium) species
(Weed Science Society of America, 2010-03)Multiyear Field data from Spain were used to model seedling emergence for three bedstraw species (Galium) that can coexist in winter cereal fields. The relationships between cumulative emergence and both growing degree ... -
Modelling leaf development in Oxalis latifolia
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (Espanya), 2010)This study was carried to develop functions that could explain the growth of Oxalis latifolia, in both early stages and throughout the season, contributing to the improvement of its cultural control. Bulbs of the Cornwall ... -
Modelling the spatial distribution of aquatic insects (Order Hemiptera) potentially involved in the transmission of Mycobacterium ulcerans in Africa
(BMC, 2018-09-06)Background: Biting aquatic insects belonging to the order Hemiptera have been suggested as potential vectors of Mycobacterium ulcerans in endemic areas for Buruli ulcer (BU). If this is the case, these insects would be ... -
Multi-species mixtures - new perspectives on models and mechanisms
(European Grassland Federation, 2010)The delivery of essential ecosystem functions (primary productivity, maintenance of soil fertility, resistance to weed invasion etc.) may be compromised by global declines in biodiversity. There is still controversy about ... -
Multi-tree woody structure reconstruction from mobile terrestrial laser scanner point clouds based on a dual neighbourhood connectivity graph algorithm
(Elsevier, 2016)A process is presented for the vector reconstruction of fruit plantations based on the model developed by Verroust and Lazarus. To solve occlusion problems, the use of a dual graph of local and extended connectivity is ... -
