Scale dependence of species–area relationships is widespread but generally weak in Palaearctic grasslands
2021
Questions: Species–area relationships (SARs) are fundamental for understanding biodiversity patterns and are generally well described by a power law with a constant exponent z. However, z-values sometimes vary across spatial scales. We asked whether there is a general scale dependence of z-values at fine spatial grains and which potential drivers influence it. Location: Palaearctic biogeographic realm. Methods: We used 6,696 nested-plot series of vascular plants, bryophytes and lichens from the GrassPlot database with two or more grain sizes, ranging from 0.0001 m² to 1,024 m² and covering diverse open habitats. The plots were recorded with two widespread sampling approaches (rooted presenc…
Fine‐grain beta diversity of Palaearctic grassland vegetation
2021
QUESTIONS: Which environmental factors influence fine-grain beta diversity of vegetation and do they vary among taxonomic groups? LOCATION: Palaearctic biogeographic realm. METHODS: We extracted 4,654 nested-plot series with at least four different grain sizes between 0.0001 m² and 1,024 m² from the GrassPlot database, covering a wide range of different grassland and other open habitat types. We derived extensive environmental and structural information for these series. For each series and four taxonomic groups (vascular plants, bryophytes, lichens, all), we calculated the slope parameter (z-value) of the power law species–area relationship (SAR), as a beta diversity measure. We tested whe…
Plant functional and taxonomic diversity in European grasslands along climatic gradients
2021
Aim European grassland communities are highly diverse, but patterns and drivers of their continental-scale diversity remain elusive. This study analyses taxonomic and functional richness in European grasslands along continental-scale temperature and precipitation gradients. Location Europe. Methods We quantified functional and taxonomic richness of 55,748 vegetation plots. Six plant traits, related to resource acquisition and conservation, were analysed to describe plant community functional composition. Using a null-model approach we derived functional richness effect sizes that indicate higher or lower diversity than expected given the taxonomic richness. We assessed the variation in abso…
Mesopolysaccharides: The extracellular surface layer of visceral organs
2020
The mesothelium is a dynamic and specialized tissue layer that covers the somatic cavities (pleural, peritoneal, and pericardial) as well as the surface of the visceral organs such as the lung, heart, liver, bowel and tunica vaginalis testis. The potential therapeutic manipulation of visceral organs has been complicated by the carbohydrate surface layer—here, called the mesopolysaccharide (MPS)—that coats the outer layer of the mesothelium. The traditional understanding of MPS structure has relied upon fixation techniques known to degrade carbohydrates. The recent development of carbohydrate-preserving fixation for high resolution imaging techniques has provided an opportunity to re-examine…
Les dynamiques du périurbain dijonnais entre 1990 et 1999
2009
Un étalement urbain accompagne désormais la croissance des villes, notamment les plus grandes. Principalement expliqué par un desserrement résidentiel, il est aussi la résultante des dynamiques de centralisation de l’emploi et de spécialisation des zones d’activité à l’intérieur des aires urbaines. L’exemple dijonnais met bien en lumière ce double mouvement qui affecte les communes de sa périphérie et contribue à accroître les mobilités. Urban sprawl arises from the growth of cities, especially of the biggest cities. This urban sprawl is accounted for mainly by residential clearing. It results also from the dynamics of centralization of employment and from specialization of activity zones i…
Akustische Masken auf dem Theater/ Maschere acustiche in teatro: Text - Sprache - Performanz/ Testo - Lingua - Performance
2019
I molteplici interessi scientifici e professionali - teatrologici, storici, linguistici, derivanti dall'attuale prassi attoriale e registica - che sono alla base di questi saggi offrono un quadro sfaccettato e complesso delle riflessioni sul discorso della comunicazione teatrale nei due paesi, le cui peculiarita, piu che le somiglianze, spiccando nel confronto, gettano una luce incrociata particolarmente interessante. Il filo rosso che si intreccia alla trama di questi contributi e senz'altro il complesso rapporto che lega la parola del testo teatrale con quella che si realizza sulla scena, ovverosia cio che in realta si puo definire lo specifico dell'evento teatrale in se, il quale si real…
Vidzemes Lielais Zviedru Kadastrs kā saimniecības vēstures avots
1942
Kadastrs - sistematizēti kādu zemes vai ūdens nogabalu vai citu objektu dati; ar nodokļiem apliekamo zemju saraksts un novērtējums pilsētās un laukos. Zemes kadastru sāka ar zemes uzmērīšanu un vērtēšanu, vienlaikus veicot muižu redukciju, atsavinot lielāko daļu muižas zemju, kuras nodeva Zviedrijas valsts pārziņā. Tas bija labi izstrādāts kadastrs, un to izmantoja no 1691. līdz 1911. gadam, t. i., 220 gadus. Tas pasaulē ir samērā mazpazīstams, un tagadējās Latvijas un Igaunijas teritorijā tam bija tikai lokāla nozīme. Muižu redukcija .17. gs. 2. pusē, pieaugot absolūtisma tendencēm Eiropā, Zviedrijas karalis Kārlis XI (Karl XI) centās nostiprināt varu visā valstī. Viens no pasākumiem bija …

Routine Use of Budesonide/Formoterol Fixed Dose Combination in Elderly Asthmatic Patients: Practical Considerations
2017
Asthma has been demonstrated to be as common in the elderly as in younger age groups. Although no specific recommendations exist to manage the disease differently in older individuals, functional features and clinical presentations may be affected by age per se, and by age-related conditions, such as comorbidities and polypharmacy. In this review article, we aimed to explore the efficacy and safety in elderly asthmatic patients of one of the most currently used inhaled treatments for asthma, that is, the fixed-dose combination of budesonide/formoterol. We attempted to address some practical questions that are relevant to the daily practice of clinicians. We focused on the efficacy and real-…
