The individual filtering rates of the cladocerans in Créteil Lake were measured daytime with 14 C‐labeled Chlorella during a seasonal survey. This mesotrophic, shallow, polymictic lake is characterized by small algae (<25 µ m) and (<1.3 mm). Multiple regression models established for each genus all cladocerans. Body length alone explained from 44 to 57% total variance Daphnia spp., Ceriodaphnia Diaphanosoma brachyurum . An additional 23–34% was attributable temperature. inclusion Chl...
In this research, a model for the estimation of antioxidant content in cherry fruits from multispectral imagery acquired drones was developed, based on machine learning methods. For two consecutive cultivation years, trees were sampled different dates and then analysed their fruits’ radical scavenging activity (DPPH) Folin–Ciocalteu (FCR) reducing capacity. Multispectral images unmanned aerial vehicles same with fruit sampling. Soil samples collected throughout study fields at end season....
Mosquito-borne diseases' impact on human health is among the most prominent of all communicable diseases. With limited pool tools to contrast these diseases, public focus remains preventing mosquito-human contacts. Applying a hierarchical spatio-temporal Bayesian model West Nile virus (WNV) surveillance data from Greece, we aimed investigate climatic and environmental factors Culex mosquitoes' population. Our analysis confirmed as major drivers WNV-transmitting-Culex mosquitoes population...
Climate can affect the geographic and seasonal patterns of vector-borne disease incidence such as West Nile Virus (WNV) infections. We explore association between climatic factors occurrence fever (WNF) or neuro-invasive (WNND) in humans Northern Greece over years 2010-2014. Time series a period 30 (1979-2008) data air temperature, relative humidity, soil volumetric water content, wind speed, precipitation representing average climate were obtained utilising ECMWF's (European Centre for...
This research is an outcome of the R&D activities Ecodevelopment S.A. (steadily supported by Hellenic Agricultural Organization—Demeter) towards offering precision farming services to rice growers. Within this framework, a new methodology for topdressing nitrogen prediction was developed based on machine learning. Nitrogen key element in culture and its rational management can increase productivity, reduce costs, prevent environmental impacts. A multi-source, multi-temporal, multi-scale...
Human and animal vector-borne diseases, particularly mosquito-borne are emerging or re-emerging worldwide. Six Aedes invasive mosquito (AIM) species were introduced to Europe since the 1970s: aegypti, Ae. albopictus, japonicus, koreicus, atropalpus triseriatus. Here, we report results of AIMSurv2020, first pan-European surveillance effort for AIMs. Implemented by 42 volunteer teams from 24 countries. And presented in form a dataset named "AIMSurv Invasive Mosquito harmonized Europe. AIM-COST...
To gain insight into the strain(s) causing human cases of West Nile virus (WNV) infection in Greece 2012, mosquitoes were collected and tested for probable WNV infection. lineage 2 sequences obtained from two 14 Culex spp. pools Xanthi Prefecture, especially municipality with highest incidence Greece. As previous years, strain contains H249P substitution NS3 protein. It seems that this specific is fully established causes large-scale outbreaks. Thus, prevention control measures have to be...
West Nile virus (WNV) emerged in central Macedonia, northern Greece, 2010. The aim of the study was to test Culex mosquitoes for genetic detection WNV and other flaviviruses, check whether correlated with occurrence human cases. During 2013, 25 780 spp. were collected from grouped into 295 pools, according collection site date, tested presence flavivirus RNA. Thirteen (4.4%) pools flavivirus-positive. lineage 2 detected nine (3.1%) insect-specific flaviviruses (ISFV) four (1.4%). Three ISFV...
Surface-water body maps are imperative for effective mosquito larvae control. This study aims to select a method the automatic and regular mapping of surface-water bodies in rice fields wetlands using Sentinel-1 synthetic aperture radar data. Four methods were adapted developed automated application: Otsu valley-emphasis algorithm, classification based on textural feature entropy, K-means unsupervised classification, Haralick's dissimilarity fuzzy-rules classification. The results assessed...
IntroductionDuring summer 2010, 262 human cases including 35 deaths from West Nile virus (WNV) infection were reported Central Macedonia, Greece. Evidence mosquitoes, birds and blood donors demonstrated that the epidemic was caused by WNV lineage 2, which until recently considered of low virulence. We conducted a household seroprevalence study to estimate spread in population during epidemic, ascertain relationship clinical disease, identify risk factors for infection. MethodsWe used...
Annual entomological surveillance programs aiming to monitor mosquito populations and record presence absence of species have been performed in Greece. We report, this study, new records expansion Aedes albopictus the islands Lesvos (region North Aegean), Crete Crete), regional units Rodopi East Macedonia-Thrace. Furthermore, Culex tritaeniorhynchus was recorded for first time Arta Epirus) northwestern
The objective of this study was to develop a methodology for mapping olive plantations on sub-tree scale. For purpose, multispectral imagery an almost 60-ha plantation in Greece acquired with Unmanned Aerial Vehicle. Objects smaller than the tree crown were produced image segmentation. Three features indicated as optimum discriminating trees from other objects plantation, rule-based classification algorithm. After limited manual corrections, final output validated by overall accuracy 93%....
We investigated the prevalence and genetic diversity of Wolbachia pipientis strains in Aedes albopictus populations Greece. Using a combination PCR Sanger sequencing techniques, we genotyped 105 mosquitoes collected across eight different administrative regions 2021. found high both male (90%) female (97%) mosquitoes. Among infected samples, 84% had double infections with wAlbA wAlbB strains, while 16% only wAlbB. Our comparison Multi-Locus Sequence Typing (MLST) profile, employing...
Summary In 2010, a West Nile virus (WNV) epidemic was reported in Central Macedonia, Northern Greece, with 197 neuroinvasive disease (WNND) cases humans. The following 3 years, WNV spreads to new areas of Greece and human reoccurred during the transmission periods. After initial outbreak, surveillance system using juvenile backyard chickens established Macedonia (after 2011 outbreak) Eastern Macedonia‐Thrace 2012 outbreak). Sera were screened for presence antibodies against cELISA serum...
The aim of this study is to develop an integrated approach soil quality and fertility assessment in high-yielding rice agro-ecosystems threatened due overexploitation resources by intensive agriculture. proposed implemented considering representative pilot fields allocated throughout a area based on the assumption that soils similar general properties present nutritional status common long-term management practices. analysis includes (a) object-based image for land zonation, (b) hot-spot...
SUMMARY 1. Based on data for 14 C‐primary production and biomass changes in a small shallow lake (Créteil Lake, France), overall phytoplankton losses were calculated through an annual cycle (November 1985‐October 1986). The summer period 1986 is compared with two other periods 1985 1980, these years corresponding to extreme levels of algal biomass. 2. Independent from the trophic state lake, populations dominated by small‐sized species (<20 μm); their high growth rate (maximal May June:...
The determination of time for grape harvest is probably the most important decision wine making producers, because grapes are not climacteric fruits and if they harvested before fully ripe their quality compromised. This sugar content, aroma color compounds increase only non-climacteric fruits. current practice determining berry ripeness includes measurements samples total soluble solids (TSS) pH, but this procedure consuming laborious. On other hand, with development unmanned aerial...
