Cleaning system, batch sorting and traceability between field-industry in the mechanical harvesting of table olives.
(2023)The table olive sector, there is no cleaning and fruit sorting by quality in the field of the harvested olive batches, nor is there an exhaustive recording of traceability. As a result, the batches are stored and shipped ... -
Comparison of Errors Produced by ABA and ITC Methods for the Estimation of Forest Inventory Attributes at Stand and Tree Level in Pinus radiata Plantations in Chile
(MDPI, 2023)Airborne laser scanning (ALS) technology is fully implemented in forest resource assessment processes, providing highly accurate and spatially continuous results throughout the area of interest, thus reducing inventory ... -
Competition modulates the response of growth to climate in pure and mixed Abies pinsapo subsp. maroccana forests in northern Morocco
(Elsevier, 2020)The effects of changes in structure and composition on the dynamics and responses of secondary forests to climate change are understudied. Secondary forests of Abies pinsapo var. maroccana are often a mosaic of patches of ... -
Contrasting Response to Drought and Climate of Planted and Natural Pinus pinaster Aiton Forests in Southern Spain
(MDPI, 2019)Extreme drought events and increasing aridity are leading to forest decline and tree mortality, particularly in populations near the limits of the species distribution. Therefore, a better understanding of the growth ... -
Cumulative Drought Stress Leads to a Loss of Growth Resilience and Explains Higher Mortality in Planted than in Naturally Regenerated Pinus pinaster Stands
(MDPI, 2018)The assessment of the long-term impacts of drought on tree growth decline using tree-ring analyses may be used to test if plantations are more vulnerable to warming after successive droughts, leading to a “cumulative ... -
Current and potential distribution areas for Nothofagus alessandrii, an endangered tree species from central Chile
(Pontificia Universidad Católica de Chile, 2012)Nothofagus alessandrii ("ruil") is an endangered species native to the Maule Coastal Forest of central Chile. Previous studies have demonstrated that the current distribution of this species and rates of deforestation ... -

Deficiencias minerales en plantas de una savia de dos especies frondosas mediterráneas (Quercus suber L. y Ceratonia siliqua L.)
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2003) -
Deficiencias nutritivas en plantas de una savia de tres especies del género Pinus sp. en cultivo hidropónico.
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2001)El objeto del presente trabajo es el estudio de los efectos de las deficiencias de nitrógeno, fósforo, potasio y hierro en tres especies de pinos mediterráneos: Pinus pinaster Ait., Pinus pinea L. y Pinus halepensis Mill. ... -
Deforestation and Biomass Production in Miombo Forest in Huambo (Angola): A Balance between Local and Global Needs
(MDPI, 2021)Miombo is one of the most widely distributed ecosystems in Angola, with a great social and environmental value. Thus, the rural population uses the biomass as fuel and miombo provides important ecosystem services, such as ... -
Deriving predictive relationships of carotenoid content at the canopy level in a conifer forest using hyperspectral imagery and model simulation
(IEEE, 2014)Recent studies have demonstrated that the R570/R515 index is highly sensitive to carotenoid (Cx + c) content in conifer forest canopies and is scarcely influenced by structural effects. However, validated methods for the ... -
Diagrama de manejo de densidad y su aplicación a raleo en bosques de segundo crecimiento de Drimys winteri en el sur de Chile
(Universidad Austral de Chile, 2011)Stand density management (DMD) diagrams are graphical models of uniform stands at different ages that reflect the relationship among size, density, competition, site occupancy and self thinning. DMDs allow planning of ... -
Differences in the Response to Acute Drought and Phytophthora cinnamomi Rands Infection in Quercus ilex L. Seedlings
(MDPI, 2018)The sustainability of “dehesas” is threatened by the Holm oak decline. It is thought that the effects of root rot on plant physiology vary depending on external stress factors. Plant growth and biomass allocation are ... -
Discriminación de bosques de Araucaria araucana en el Parque Nacional Conguillío, centro-sur de Chile, mediante datos Landsat TM
(Universidad Austral de Chile, 2011)Araucaria forests (Araucaria araucana) have a tremendous ecological relevance; however, the information concerning their spatial distribution is still insufficient. They have only been classified according to small management ... -

(UCOPress, 2018)Un Marteloscopio es una herramienta didáctica para el entrenamiento selvícola (ejercicios virtuales de selección de árboles). La disponibilidad de los datos del rodal forestal en un dispositivo móvil (tablet) en combinación ... -
Distribution and Factors Influencing Organic Carbon Stock in Mountain Soils in Babia Góra National Park, Poland
(MDPI, 2019)The objective of this study was to determine the soil organic carbon stock (T-SOC stock) in different mountain soils in the Babia Góra National Park (BNP). Environmental factors, such as the topography, parent material, ... -
Divergent abiotic spectral pathways unravel pathogen stress signals across species
