Coupling two radar backscattering models to assess soil roughness and surface water content at farm scale
2013
Remote sensing techniques are useful for agro-hydrological monitoring at the farm scale because the availability of spatially and temporally distributed data improves agricultural models for irrigation and crop yield optimization under water scarcity conditions. This research focuses on the surface water content retrieval using active microwave data. Two semi-empirical models were chosen as these showed the best performances in simulating cross and co-polarized backscatter. Thus, these models were coupled to obtain reliable assessments of both soil water content and soil roughness. The use of the coupled model enables one to avoid using roughness measured in situ. Remote sensing images and …
Gender Representation of Athletes in Finnish and Swedish Tabloids : A quantitative and qualitative content analysis of Athens 2004 and Turin 2006 Oly…
2016
AbstractThe study examines quantitatively and qualitatively gender representation in Finnish and Swedish tabloids’ sports coverage during Athens 2004 summer and Turin 2006 winter Olympics. Several media studies argue that sports journalism marginalises women’s sports and sexualises female athletes. The results of this study show that male athletes received more coverage than female athletes in every tabloid, but when the number of domestic participants and their level of success were considered, neither country’s tabloids quantitatively marginalised women’s sports. Qualitative analysis found that research stereotypes showing trivialisation and sexualisation of female athletes were incorrect…
Long-term dynamics of Collembola in a pine forest ecosystemProceedings of the Xth international Colloquium on Apterygota, České Budějovice 2000: Apte…
2002
Summary Biomonitoring data on soil Collembola collected over a six year period (1992-1997) in Scots pine ( Pinus sylvestris L.) forest in the Northern Vidzeme Biosphere Reserve, northern Latvia, are analysed. Monitoring was conducted in three plots: young (30-40 years), middle-aged (50—70 years), and old (150—200 years) pine stands. Sampling was performed once a year, in late August or early September, according to a systematic sampling scheme. One hundred soil cores (5 cm 2 × 10 cm) were taken within each plot every year, Collembola were extracted from the cores by using a modified high gradient extractor. During the monitoring period, there was a tendency of climate warming between 1992 a…
Distribution of aquatic Oligochaeta in the Finnish Lake District
1980
SUMMARY. The distribution of oligochaetes was examined at sampling stations grouped into three types: (1), in eutrophic and dystrophic areas or in areas polluted by pulp-mill wastewaters; (2), slightly eutrophic stations; (3), ‘clean’ stations unaffected by sewage or other inputs. Limnodrilus hoffmeisteri and Potamothrix hammoniensis were practically the only species in group 1, and the same species accounted for two thirds of the total numbers in group 2, although Peloscolex ferox and some other species also occurred. At the cleanest stations the dominating species were P. ferox, Psammoryctides barbatus, Stylodrilus heringianus and Tubifex tubifex. A factor analysis showed that L. hoffmeis…
Draft Genome Sequences of Vibrio renopiscarius Strains CECT 8603T and CECT 8604, Two Marine Gammaproteobacteria Isolated from Cultured Gilthead Sea B…
2015
ABSTRACT Vibrio renopiscarius DCR 1-4-2 T (CECT 8603 T ) and DCR 1-4-12 (CECT 8604) were isolated from healthy gilthead sea bream ( Sparus aurata ) from Mediterranean fish farms (Castellón, Spain). Their draft genome sequences (30 and 44 contigs, respectively) have 4.3 Mbp and a G+C content of 45.2 mol% and contain almost 3,700 protein-encoding genes.
Growth and biomass partitioning of Arbutus unedo, Laurus nobilis, Phillyrea angustifolia and Rhamnus alaternus seedlings under water deficit
2013
Water scarcity in the Mediterranean areas is very common and the selection of drought tolerant species is a priority for landscaping purposes in the Mediterranean areas. The objective of this study was to evaluate the effect of water deficit on growth and biomass partitioning of Arbutus unedo, Laurus nobilis, Phillyrea angustifolia and Rhamnus alaternus. Seventy-two seedlings per species were grown in the greenhouse in 4-liter pots and three water regimes were imposed starting on 6 April and until 9 June, 2010. One-third of the plants was well irrigated to maintain soil water content in the 25-35% range (CTR); a second group of plants was deficit-irrigated to maintain soil water content in …
Global warming affect Collembola community: A long-term study
2006
Summary Long-term (1992–2002) effects of climate changes on soil Collembola in Scots pine Pinus sylvestris forests in North Vidzeme Biosphere Reserve (northern Latvia) are investigated. The study was carried out in three forest stands of different age, young (30–40 years), middle aged (50–70 years), and old (150–200 years). One hundred soil samples were collected within each sampling site once a year in autumn over a period of 11 years. In total, 66 species of Collembola were found. Species richness varied between 47 and 56 and density of Collembola from 7300 to 8300 ind m−2. A statistically significant increase in the sums of positive air temperatures (⩾4 °C) was recorded during the period…
High dietary inclusion level of fresh herring impairs growth of rainbow trout, Oncorhynchus mykiss
1998
Abstract One-year old rainbow trout (initially 350–670 g) were fed for 15 weeks diets containing various amounts of water (23–67%). This was achieved by replacing fish meal with Baltic herring. The growth of rainbow trout, whether measured as wet weight, protein or energy, was impaired when 50–55% dietary water was fed. The fish compensated for increasing dietary water content by consuming more diet so that the dry matter intake of the diets with 23 and 67% water were equal. Partitioning of growth into protein and lipid as well as protein and energy retention efficiencies were unaffected by dietary water. It is suggested that there is a metabolic cost of consuming more food when compensatin…
The diet of spotted cuscus (Spilocuscus maculatus) in natural and captivity habitat
2010
Saragih EW, Sadsoeitoeboen MJ, Pattiselanno F. 2010. The diet of spotted cuscus (Spilocuscus maculatus) in natural andcaptivity habitat. Nusantara Bioscience 2: 78-83. The ex-situ conservation of cuscus (Spilocuscus maculatus) under captivatingcondition is an alternative solution to protect cuscus from extinction. Diets became the main factor in order to support the domesticationprocess. Particular studies on habitat and diet of cuscus have been carried out however there is still limited information on the nutritionaspects of cuscus food. This study aimed to determine the diet type, palatability and nutrient in both natural habitat and captivatingcondition. The results indicated that there …
A new calibration of the effective scattering albedo and soil roughness parameters in the SMOS SM retrieval algorithm
2017
Abstract This study focuses on the calibration of the effective vegetation scattering albedo (ω) and surface soil roughness parameters (H R , and N Rp , p = H,V) in the Soil Moisture (SM) retrieval from L-band passive microwave observations using the L-band Microwave Emission of the Biosphere (L-MEB) model. In the current Soil Moisture and Ocean Salinity (SMOS) Level 2 (L2), v620, and Level 3 (L3), v300, SM retrieval algorithms, low vegetated areas are parameterized by ω = 0 and H R = 0.1, whereas values of ω = 0.06 − 0.08 and H R = 0.3 are used for forests. Several parameterizations of the vegetation and soil roughness parameters (ω, H R and N Rp , p = H,V) were tested in this study, tre…
