Identificación de los Indicadores de seguimiento de las acciones de conservación. Acción A1 “Diagnosis, Análisis territorial e Identificación de Indicadores"

Las acciones de conservación de LIFE FLUVIAL precisan de una evaluación periódica de sus repercusiones sobre el hábitat 91E0* y el hábitat 9230 (los dos hábitats objetivo del proyecto). Cada socio en sus territorios debe llevar a cabo un seguimiento con motivo de la acción D1 que permita evaluar la efectividad de las actuaciones de restauración (acciones C) y realizar una toma de decisiones de acuerdo a los resultados de dicho monitoreo, que pueda incluir cambios en las actuaciones previstas o la ejecución de nuevas medidas. En consecuencia, en el presente documento se establecen los indicadores de seguimiento a emplear en la acción D1 de LIFE FLUVIAL, así como la metodología para su aplicación. Los objetivos del seguimiento son: A. Vigilar la evolución del proceso de restauración B. Controlar los cambios que se produzcan C. Detectar y corregir la aparición de efectos indeseables D. Favorecer los procesos que se entiendan beneficiosos para recuperar la naturalidad y biodiversidad del lugar. En todo caso, hay que tener en cuenta que la duración del proyecto se queda corta para poder abarcar todo el proceso de recuperación de la cubierta vegetal propiciado por las acciones de conservación, de modo que, probablemente, los resultados del seguimiento relativos a algunos parámetros no presentarán valores especialmente significativos, debiendo interpretarse entonces como tendencias de la evolución de los hábitats objetivo en los enclaves de actuación.info:eu-repo/semantics/publishedVersio

Habitat specificity of a threatened and endemic cliff-dwelling halophyte

Research ArticleCoastal areas and other saline environments are major contributors to regional and global biodiversity patterns. In these environments, rapidly changing gradients require highly specialized plants like halophytes. In European coastal cliff-tops, rocky and sandy seashores, and saltmarshes, typical halophytes from the genus Limonium are commonly found. Among them, the aneuploid tetraploid (2n ¼ 4x ¼ 35, 36, 37) Limonium multiflorum, endemic to the west coast of Portugal, is an interesting case study for investigating the ecology and conservation of a halophyte agamospermic species. Although it is listed in the IUCN red list of threatened species, information on its population size or rarity, as well as its ecology, in some respects is still unknown. Field surveys in the largest known population were performed (Raso cape, Portugal) in order to determine habitat requirements and conservation status. A total of 88 quadrats were monitored, 43 of which contained at least one L. multiflorum individual. For each sampled quadrat, four abiotic and four biotic variables as well as two spatially derived variables were recorded. Principal component analysis and cluster analysis showed narrow habitat specificity for this species which appeared to be intolerant to competition with invasive alien plants. We conclude that in situ conservation in a local ‘hotspot’ of this rare and vulnerable species emerges as a priority in order to ensure that biodiversity is not los

Twenty years of coordination technologies: State-of-the-art and perspectives

Since complexity of inter- and intra-systems interactions is steadily increasing in modern application scenarios (e.g., the IoT), coordination technologies are required to take a crucial step towards maturity. In this paper we look back at the history of the COORDINATION conference in order to shed light on the current status of the coordination technologies there proposed throughout the years, in an attempt to understand success stories, limitations, and possibly reveal the gap between actual technologies, theoretical models, and novel application needs

The Complex of Sphingomonas elodea ATCC 31461 Glucose-1-Phosphate Uridylyltransferase with Glucose-1-Phosphate Reveals a Novel Quaternary Structure, Unique among Nucleoside Diphosphate-Sugar Pyrophosphorylase Members▿ †

Gellan gum is a widely used commercial material, available in many different forms. Its economic importance has led to studies into the biosynthesis of exopolysaccharide gellan gum, which is industrially prepared in high yields using Sphingomonas elodea ATCC 31461. Glucose-1-phosphate uridylyltransferase mediates the reversible conversion of glucose-1-phosphate and UTP into UDP-glucose and pyrophosphate, which is a key step in the biosynthetic pathway of gellan gums. Here we present the X-ray crystal structure of the glucose-1-phosphate uridylyltransferase from S. elodea. The S. elodea enzyme shares strong monomeric similarity with glucose-1-phosphate thymidylyltransferase, several structures of which are known, although the quaternary structures of the active enzymes are rather different. A detailed comparison between S. elodea glucose-1-phosphate uridylyltransferase and available thymidylyltransferases is described and shows remarkable structural similarities, despite the low sequence identities between the two divergent groups of proteins
