Application of a Split-Window Algorithm to Estimate Land Surface Temperature from NOAA-AVHRR Data
2006
Estimaciones de temperatura de la superficie terrestre, en días parciales a completamente despejados, fueron realizadas a partir de los datos proporcionados por el sensor Advanced Very High Resolution Radiometer (AVHRR), a bordo de la serie de satélites de la National Oceanic and Atmospheric Administration (NOAA) por aplicación de un algoritmo basado en el método de Split-Window. El algoritmo utilizado supone correcciones por emisividad y contenido de vapor de agua atmosférico, y fue validado con mediciones de temperatura de la superficie terrestre realizadas en terreno. Para esto, un data logger LI-1000 se instaló en la Estación Agrometeorológica dependiente del Instituto de Investigacione…
Importance of millipedes (Diplopoda) in the autumn-winter diet of Scolopax rusticola
2019
Authors examined the autumn-winter diet of the woodcock Scolopax rusticola from 407 gizzard samples originating from Crimea and Italy, resulting in a high number of millipedes (Diplopoda) in all the samples; this prey item was particularly important in terms of weight percentage. The authors consider that calcium, highly present in millipedes, should be an important source for the woodcocks’ metabolism during the autumn-winter seasons.
First report on the helminthfauna of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula
2016
Summary Information about the prevalence of helminth parasites of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula is almost non-existent and there is no reliable data reported from Spain. Fourteen A. flavicollis from the Erro River valley (Navarre, Spain) were examined for endoparasites, between February 2001 and July 2002. Thirteen specimens (92.9 %) of the total sample were parasitized by at least one of the following six helminth species: one trematode (Corrigia vitta), one cestode (Taenia parva larvae) and four nematodes (Trichuris muris, Calodium hepaticum, Heligmosomoides polygyrus and Syphacia stroma). This is the first report about the helminthfauna of A. fla…
Genetic variability at αs2-casein gene in Girgentana dairy goat breed
2014
Casein genes are highly polymorphic and the high degree of variability has qualitative and quantitative effects on milk composition thereby affecting chemical, physical and technological properties of goat milk. The aim of this work was to evaluate the genetic polymorphisms of the αs2-casein (CSN1S2) gene in the endangered Girgentana dairy goat breed in order to assess the genotypes distribution, as it is known genotype influences technological and nutritional milk properties. The study was performed on 207 sample of Girgentana goat breed, analysed with different PCR protocols. The most frequent alleles was A (0.722), followed by F (0.225), C (0.051) and E (0.002) while B, D and 0 alleles w…
The Use of Stable Isotope Ratio Analysis to Trace European Sea Bass (D. labrax) Originating from Different Farming Systems
2020
This study aimed to determine whether isotopic ratio mass spectrometry (IRMS) can discriminate farmed European sea bass according to different farming systems and geographic origins. Dicentrarchus labrax of commercial size from three different rearing systems (concrete tank inland, sea cages, and extensive methods in valleys or salt works) were collected at the trading period (autumn&ndash
