Multiple pathway succession in coastal Tsuga heterophylla, Thuja plicata and Abies amabilis forests on northeastern Vancouver Island, British Columbia
(NRC Research Press, 2014)
Artículo / Artikulua,
Sustainable forest practices are often designed to mimic natural disturbance and successional processes, yet succession is poorly understood in many ecosystems. On northeastern Vancouver Island, the ‘disturbance hypothesis’ ...
Determining suitable selection cutting intensities based on long term observations on above-ground forest carbon, growth, and stand structure in Changbai Mountain, Northeast China
(Taylor & Francis, 2014)
Artículo / Artikulua,
We studied the effects of different cutting intensities (0%, 5-10%, 15%, and 20% basal area removal) on stand growth, structure, and net carbon storage in spruce-fir (Picea asperata Mast.-Abies fabri Mast. Craib) and ...
Soil organic matter: a sustainability indicator for wildfire control and bioenergy production in the urban/forest interface.
(The Soil Science Society of America, Inc., 2014)
Artículo / Artikulua,
Many rural communities in British Columbia (western Canada) are increasingly at risk from wildfire as temperatures rise and droughts become more frequent. In addition, these communities are also faced with rising fuel ...
Significant increase in ecosystem C can be achieved with sustainable forest management in subtropical plantation forests
(Public Library of Science, 2014)
Artículo / Artikulua,
Subtropical planted forests are rapidly expanding. They are traditionally managed for intensive, short-term goals that often lead to long-term yield decline and reduced carbon sequestration capacity. Here we show how it ...
Nodule carbohydrate catabolism is enhanced in the Medicago truncatula A17-Sinorhizobium medicae WSM419 symbiosis
(Frontiers Media, 2014)
Artículo / Artikulua,
The symbiotic association between Medicago truncatula and Sinorhizobium meliloti is a well-established model system in the legume–Rhizobium community. Despite its wide use, the symbiotic efficiency of this model has been ...
Drought stress provokes the down-regulation of methionine and ethylene biosynthesis pathways in Medicago truncatula roots and nodules
(Wiley, 2014)
Artículo / Artikulua,
Symbiotic nitrogen fixation is one of the first physiological
processes inhibited in legume plants under water-deficit conditions.
Despite the progress made in the last decades, the
molecular mechanisms behind this ...
Vidrios romanos de Bracara Augusta (Portugal): análisis arqueométrico
(Universidad Nacional de Educación a Distancia (UNED), 2014)
info:eu-repo/semantics/article,
En este trabajo se han estudiado vidrios romanos de Bracara Augusta, actualmente Braga (Portugal), a través de su composición química, analizando los constituyentes mayoritarios, minoritarios y traza mediante espectrometría ...
Nodule performance within a changing environmental context
(Elsevier, 2014)
info:eu-repo/semantics/article,
Global climate models predict that future environmental conditions will see alterations in temperature, water availability and CO2 concentration ([CO2]) in the atmosphere. Climate change will reinforce the need to develop ...
A proteomic approach reveals new actors of nodule response to drought in split-root grown pea plants
(Wiley, 2014)
info:eu-repo/semantics/article,
Drought is considered the more harmful abiotic stress resulting in crops yield loss. Legumes in symbiosis with rhizobia are able to fix atmospheric nitrogen. Biological nitrogen fixation (SNF) is a very sensitive process ...
Split‐root systems applied to the study of the legume‐rhizobial symbiosis: what have we learned?
(Wiley, 2014)
info:eu-repo/semantics/article,
Split-root system (SRS) approaches allow the differential treatment of separate and independent root systems, while sharing a common aerial part. As such, SRS is a useful tool for the discrimination of systemic (shoot ...
