Sectoral policies as drivers of forest management and ecosystems services: A case study in Bavaria, Germany
2023
European countries have national sectoral polices to regulate and promote the provision of a wide range of forest ecosystems services (FES). However, potential incoherencies among these policies can negatively affect the efficient provision of FES. In this work, we evaluated the coherence among three national policies from Germany and their ability to effectively provide FES in the future: the Forest Strategy 2020 (FS), the National Strategy on Biological Diversity (BDS), and the German National Policy Strategy on Bioeconomy (BES). Using forest inventory data from the Federal State of Bavaria, we simulated a range of forest management options under three climate trajectories for 100 years i…
Urban forest soils harbour distinct and more diverse communities of bacteria and fungi compared to less disturbed forest soils.
2022
Anthropogenic changes to land use drive concomitant changes in biodiversity, including that of the soil microbiota. However, it is not clear how increasing intensity of human disturbance is reflected in the soil microbial communities. To address this issue, we used amplicon sequencing to quantify the microbiota (bacteria and fungi) in the soil of forests (n=312) experiencing four different land uses, national parks (set aside for nature conservation), managed (for forestry purposes), suburban (on the border of an urban area) and urban (fully within a town or city), which broadly represent a gradient of anthropogenic disturbance. Alpha diversity of bacteria and fungi increased with increasin…
Scientific Opinion addressing the state of the science on risk assessment of plant protection products for in‐soil organisms
2017
Abstract Following a request from EFSA, the Panel on Plant Protection Products and their Residues developed an opinion on the science behind the risk assessment of plant protection products for in‐soil organisms. The current risk assessment scheme is reviewed, taking into account new regulatory frameworks and scientific developments. Proposals are made for specific protection goals for in‐soil organisms being key drivers for relevant ecosystem services in agricultural landscapes such as nutrient cycling, soil structure, pest control and biodiversity. Considering the time‐scales and biological processes related to the dispersal of the majority of in‐soil organisms compared to terrestrial non…
Isolation and characterization of microsatellite markers in the liver fluke (Fasciola hepatica)
2004
PRIMER NOTE; International audience; Six microsatellite markers were isolated from Fasciola hepatica, a re-emerging parasite that causes important veterinary and public health problems. In a sample of 52 liver flukes from a region of hyperendemicity (Bolivian Altiplano), five microsatellite were polymorphic. Our results showed that liver flukes present important genetic variability, suggesting a preferential outcrossing reproduction mode for this hermaphroditic parasite.
Biogeographic patterns of base-rich fen vegetation across Europe
2014
International audience; Questions: What is the distribution of base-rich fen vegetation and the specia- list species along European biogeographic regions? How do the gradients in spe- cies composition correlate to geography and climate at continental scale? What are the implications of such patterns for the classification of these habitats?Location: Fifteen countries of Central, Western and Northern Europe.Methods: We compiled a vegetation plot database of base-rich fens and related communities including vascular plants and bryophytes. The initial data set with 6943 plots was filtered according to the presence of specialists using discriminant analysis. We used DCA to analyse the correlatio…

Aportaciones al conocimiento de los mosquitos (Diptera, Culicidae) de alta montaña presentes en la Península Ibérica
2009
Several larval samplings of mosquitoes (Diptera, Culicidae) in different mountainous regions of the peninsular Spain were carried out. A total of 2796 specimens belonging to 18 species were collected, nevertheless the 72.5 % of these finds includes only three of them (Cx. hortensis hortensis, Cx. pipiens and Cs. longiareolata). The adaptation capacity to a varied typology of water bodies together with the marked multivoltinism that characterizes their biotic cycles are postulated as two of the principal reasons that explain their abundances. The altitudinal distribution as well as some information about the bioecology of all the species captured are also exposed.
Palermo habitat multi-specie. Per un'integrazione fra uomo, natura e animali nella città neocosmopolita
2021
Le città sono per molti versi habitat cosmopoliti perché ospitano una grande varietà umana, animale e vegetale. Così come in natura la biodiversità è più ricca laddove maggiore è l’eterogeneità ambientale, anche nei contesti antropizzati si verifica lo stesso fenomeno (Mainardi, 2016). Parchi, edifici, campanili, insenature offrono una pluralità di habitat e spazi per altre specie che coesistono con l’uomo da sempre e si sovrappongono agli spazi di vita degli esseri umani, dando vita a dinamiche di convivenza (non sempre pacifica) multi-specifiche. L’attuale situazione pandemica ha generato le condizioni per cui la nostra specie ha potuto osservare nuovamente le altre che la circondano, ani…
I musei naturalistici come presidi ambientali e culturali. L'Orto botanico di Palermo
2013
La funzione degli Orti botanici, fondamentalmente, si esplica nella conservazione, nella ricerca scientifica, nelle attività espositive ed educative. I punti di forza dell’azione sociale di questi tipi di musei deriva sia dalla capacità di produrre e diffondere la conoscenza scientifica, sia dalla ricchezza patrimoniale posseduta. Una serie di emergenze planetarie e le prospettive incerte per l’ambiente, le società, le economie di tutte le nazioni del mondo configurano lo scenario d’oggi. Questa situazione richiede la costruzione collettiva di nuove forme di sentire, pensare e agire nella ricerca di soluzione ai problemi contemporanei. Si tratta quindi, per i musei scientifici, di intrapren…
Checklist of the Mammal Collection Preserved at the University of Palermo under the Framework of the National Biodiversity Future Center
2023
The latest reorganization of the Vertebrate collections preserved at the “Pietro Doderlein” Museum of Zoology of the University of Palermo (Italy) has made it possible to draw up a check-list of the Mammal taxa present in the stuffed (M), fluid-preserved (ML) and anatomical (AN) collections. The intervention was planned under the National Biodiversity Future Center (NBFC) agenda, focused on the enhancement of Italian natural history museums. The growing interest in museum collections strongly demands databases available to the academic and policy world. In this paper, we record 679 specimens belonging to 157 specific taxa arranged in 58 families and 16 orders. Most of the species (75.1%) co…
