Carbon use efficiency variability from MODIS data
2017
[EN] Carbon use efficiency (CUE) describes how efficiently plants incorporate the carbon fixed during photosynthesis into biomass gain and can be calculated as the ratio between net primary production (NPP) and gross primary production (GPP). In this work, annual CUE has been obtained from annual GPP and NPP MODIS products for the peninsular Spain study area throughout eight years. CUE is spatially and temporally analyzed in terms of the vegetation type and annual precipitation and annual average air temperature. Results show that dense vegetation areas with moderate to high levels of precipitation present lower CUE values, whereas more arid areas present the highest CUE values. However, th…
La estrategia empresarial para la gestión de emisiones de gases efecto invernadero
2022
Esta tesis doctoral plantea en primer lugar analizar la calidad y nivel de divulgación de información sobre la acción climática en las empresas colombianas mediante una análisis regional y sectorial. Para desarrollar este propósito este trabajo se centra en el Objetivo de Desarrollo Sostenible 13 (ODS 13) el cual llama a tomar medidas urgentes para luchar contra el cambio climático y sus impactos. Este estudio se enfoca principalmente en la meta 13.2 la cual establece la incorporación de medidas relacionadas con políticas, estrategias y planes de cambio climático. Este objetivo incluye información relacionada con las estrategias de adaptación al cambio climático (información cualitativa), y…
CHANGE IN VOLUME AND MORPHOLOGY IN CULTURES OF OLEISPIRA ANTARCTICA AS A FUNCTION OF TEMPERATURE AND SUBSTRATES USED
2015
Bacterial population under nutritional and physic stress react in order to adequate cell metabolism and physiology to stressful conditions. One of the most frequently observed behaviours in the stress-starvation response of gram-negative bacteria is the size reduction and cell morphology conversion from rod to resistant shape-form. In such framework, we report here on morphology (cell volume and cell shape) variations in psychrophilic strain Oleispira antarctica RB 8T under different growth temperature and different hydrocarbons mixtures sources. Six different hydrocarbons mixtures (car commercial diesel, commercial crude oil engine; 2 different bilge waters, military jet fuel and crude oil…
Análisis bibliométrico y sistémico de la relación entre la gestión y el carbono
2022
[EN] This paper aims to present a bibliometric and systemic analysis of the Bibliographic Portfolio (BP) jointly examining the literature related to topics like “Greenhouse gas,” mainly carbon, and “Management,” as published in databases data such as Web of Science and Scopus in the field of economic and social sciences. The Knowledge and Constructivist Development Process methodology —Proknow-C— was used to establish the final portfolio and through the VosViewer program were mapped the various groups or relationships between the studied literature. The paper presents the theoretical and methodological aspects focusing on the areas and countries of study and highlighting the most relevant a…
Intrinsic bioremediation potential of a chronically polluted marine coastal area.
2015
A microbiological survey of the Priolo Bay (eastern coast of Sicily, Ionian Sea), a chronically polluted marine coastal area, was carried out in order to discern its intrinsic bioremediation potential. Microbiological analysis, 16S rDNA-based DGGE fingerprinting and PLFAs analysis were performed on seawater and sediment samples from six stations on two transects. Higher diversity and variability among stations was detected by DGGE in sediment than in water samples although seawater revealed higher diversity of culturable hydrocarbon-degrading bacteria. The most polluted sediment hosted higher total bacterial diversity and higher abundance and diversity of culturable HC degraders. Alkane- an…
