Living on the edge: assessing the extinction risk of critically endangered Bonelli’s eagle in Italy
2012
Background: The population of Bonelli’s eagle (Aquila fasciata) has declined drastically throughout its European range due to habitat degradation and unnatural elevated mortality. There are less than 1500 breeding pairs accounted for in Europe, and the species is currently catalogued as Critically Endangered in Italy, where the 22 territories of Sicily, represent nearly 95% of the entire Italian population. However, despite national and European conservation concerns, the species currently lacks a specific conservation plan, and no previous attempts to estimate the risk of extinction have been made. Methodology/Principal Findings: We incorporated the most updated demographic information ava…
Nest Site Selection by Kentish Plover Suggests a Trade-Off between Nest-Crypsis and Predator Detection Strategies
2014
Predation is one of the main causes of adult mortality and breeding failure for ground-nesting birds. Micro-habitat structure around nests plays a critical role in minimizing predation risk. Plovers nest in sites with little vegetation cover to maximize the incubating adult visibility, but many studies suggest a trade-off between nest-crypsis and predator detection strategies. However, this trade-off has not been explored in detail because methods used so far do not allow estimating the visibility with regards to critical factors such as slope or plant permeability to vision. Here, we tested the hypothesis that Kentish plovers select exposed sites according to a predator detection strategy,…
Solving Man-Induced Large-Scale Conservation Problems: The Spanish Imperial Eagle and Power Lines
2011
[Background] Man-induced mortality of birds caused by electrocution with poorly-designed pylons and power lines has been reported to be an important mortality factor that could become a major cause of population decline of one of the world rarest raptors, the Spanish imperial eagle (Aquila adalberti). Consequently it has resulted in an increasing awareness of this problem amongst land managers and the public at large, as well as increased research into the distribution of electrocution events and likely mitigation measures.
Biomonitoring exposure assessment to contemporary pesticides in a school children population of Spain
2013
The exposure to pesticides amongst school-aged children (6-11 years old) was assessed in this study. One hundred twenty-five volunteer children were selected from two public schools located in an agricultural and in an urban area of Valencia Region, Spain. Twenty pesticide metabolites were analyzed in children's urine as biomarkers of exposure to organophosphate (OP) insecticides, synthetic pyrethroid insecticides, and herbicides. These data were combined with a survey to evaluate the main predictors of pesticide exposure in the children's population. A total of 15 metabolites were present in the urine samples with detection frequencies (DF) ranging from 5% to 86%. The most frequently detec…
Changes in the Effect of Heat on Mortality in the Last 20 Years in Nine European Cities. Results from the PHASE Project
2015
The European project PHASE aims to evaluate patterns of change in the temperature–mortality relationship and in the number of deaths attributable to heat in nine European cities in two periods, before and after summer 2003 (1996–2002 and 2004–2010). We performed age-specific Poisson regression models separately in the two periods, controlling for seasonality, air pollution and time trends. Distributed lag non-linear models were used to estimate the Relative Risks of daily mortality for increases in mean temperature from the 75th to 99th percentile of the summer distribution for each city. In the recent period, a reduction in the mortality risk associated to heat was observed only in Athens,…
Urban green and grey space in relation to respiratory health in children
2017
We assessed the effect of three different indices of urban built environment on allergic and respiratory conditions.This study involved 2472 children participating in the ongoing INMA birth cohort located in two bio-geographic regions (Euro-Siberian and Mediterranean) in Spain. Residential surrounding built environment was characterised as 1) residential surrounding greenness based on satellite-derived normalised difference vegetation index (NDVI), 2) residential proximity to green spaces and 3) residential surrounding greyness based on urban land use patterns. Information on wheezing, bronchitis, asthma and allergic rhinitis up to age 4 years was obtained from parent-completed questionnair…
Protective role of the Mediterranean diet on several cardiovascular risk factors: Evidence from Sicily, southern Italy
2014
Background and aims: Epidemiological studies conducted in European countries demonstrated that the adoption of a Mediterranean diet protect against clustered risk factors but those evaluating such benefits specifically in southern Italy are scarce. Thus, the aim of this study was to assess the association between the adherence to the Mediterranean diet and cardiovascular risk factors obesity, diabetes, and hypertension. Methods and results: A cross-sectional population-based survey including 3090 subjects was conducted in Sicily, southern Italy. Food intake was evaluated through a validated food frequency questionnaire and adherence to the dietary pattern was assessed using the MedDietScore…
Human Biomonitoring of food contaminants in Spanish children: Design, sampling and lessons learned
2017
Abstract Human Biomonitoring (HBM) studies are highly useful for evaluating population exposure to environmental contaminants and are being carried out in increasing numbers all over the world. The use of HBM in the field of food safety, in a risk assessment context, presents a growing interest as more health-based guidance values (HBGV) in biological matrices are derived, and can be used in a complementary way to the external exposure approaches such as total diet studies or surveillance programmes. The aims of the present work are: i) to describe the methodological framework of the BIOVAL study, a cross-sectional HBM program carried out by the Health Department of the Regional Government …
Sunscreen Products as Emerging Pollutants to Coastal Waters
2013
A growing awareness of the risks associated with skin exposure to ultraviolet (UV) radiation over the past decades has led to increased use of sunscreen cosmetic products leading the introduction of new chemical compounds in the marine environment. Although coastal tourism and recreation are the largest and most rapidly growing activities in the world, the evaluation of sunscreen as source of chemicals to the coastal marine system has not been addressed. Concentrations of chemical UV filters included in the formulation of sunscreens, such as benzophehone 3 (BZ-3), 4-methylbenzylidene camphor (4-MBC), TiO2 and ZnO, are detected in nearshore waters with variable concentrations along the day a…
Geoscience Teaching and Student Interest in Secondary Schools-Preliminary Results from an Interest Research in Greece, Spain and Italy.
2013
The results of a topic-interest study on geosciences among 14- to 17-year-old school students are reported. The research was organized in the framework of the European project Geoschools to investigate the interest of students in the context of teaching strategies for geosciences in secondary schools. A questionnaire was designed as the main data-collection tool, based on the results of a comparison on geosciences curricula among the five European countries (Austria, Greece, Portugal, Italy, and Spain) which are the partners in the GEOschools project. The present study focuses on results from Greece and Spain but also includes preliminary results from Italy, for comparison purposes. Questio…
