Within the Mediterranean level of Alberes chain, 186 samples were taken in different formations from grassland to forest, with presence-absence sampling bird and plant species, estimation relative cover 7 vegetation layers, plus rock itself. After multidimensional ordination (Correspondence Analysis) birds x stations matrix, multiple correlation first factor F1 C.A. 8 values, a model results which, (1) proves that F. is expression progressive evolution structure, (2) shows there logarithmic...
Abstract Aim To test whether bird assemblages are shifting upwards in their elevational distribution synchrony with current climate warming and/or habitat changes. Location A gradient of elevation the Italian Alps (Alta Valsessera, Piedmont). Methods We used data from two recent atlas surveys performed on a 1 × km grid at an 11‐year interval (1992–94 and 2003–05). modelled avifaunal composition, using sample‐based approach, effort to detect evidence for upward shift zonation. Changes species...
We used measurements of museum skins to assess morphological differences between the 22 currently recognized species wheatear and identify correlations features, behavioural traits degrees sympatry species. Ground‐dwelling steppe‐like habitats have long tarsi, claws short tails; some are migratory pointed wings non‐emarginated primaries ( O. isabellina oenanthe ), while others sedentary more rounded slotted bottae , heuglini pileata ).

Abstract Burning has traditionally been used in the southern French Alps to maintain open lands for grazing. In context of land use abandonment, prescribed burning may be only realistic practical tool available oppose encroachment by woody plants numerous mountainous landscapes. Although recently developed as a modern wildfire prevention and management pastoral grasslands, this practice is now becoming widespread, which raises issue its impact on fauna general, endangered species particular....
Habitat expansion is a commonly recognized feature of the insular syndrome. It has been explained either by restricted dispersal, intraspecific spillover resulting from density inflation, benign and predictable climate, or ecological release that results species impoverishment. The latter hypothesis frequently invoked to explain shifts and/or broadenings elevational ranges on islands. In this paper, we compared distribution 85 terrestrial breeding bird Mediterranean island (Corsica) with...
Annual land-fast ice, particularly an unconsolidated layer or “platelet ice-like” (PLI), was sampled in spring 1995 to study the spatial and short-term variations of ice-associated diatoms. Under-ice water, a lead small polynyas were also sampled. Along 7 km seaward transect geographical gradient evident, with some rare diatom species present only offshore PLI, whereas others (mainly pennate diatoms) ubiquitous. The dense microphytic PLI community as well phytoplankton diatom-dominated, but,...
Abstract Aim To identify the ecological factors (related to vegetation, altitude, climate, or geomorphology) that could explain main gradients of avifaunal richness and composition in arid environments Central Iran. Location The study was carried out two nearby semi‐arid protected areas Ispahan province: Kolah‐Ghazi National Park ( c. 50,000 ha; 1540–2535 m a.s.l.) Mouteh Wildlife Refuge 220,000 1493–2900 a.s.l.). Annual average precipitation temperature range from 155–205 mm 15–19.5 °C,...
A four year study of the impact fire on different types Mediterranean vegetation has been carried out in Eastern part Pyrenean range (Département des Pyrénées-Orientales, France). Following fire, a number transient plant species colonize open ground, while original regenerates from stumps, rhizomes or buried seeds. This results an increase richness at this stage. The time necessary for bird communities to reach their pre-fire composition and population levels differs Cork-oak Holm-oak...
Abstract Post‐disturbance survival is a key factor in the onset of secondary successions. Here we analyse capture‐recapture data from two before/after disturbance studies to estimate effect fire on local bird survival. Analyses six species at Mediterranean shrubland sites were combined using meta‐analysis approach. Two warblers, Sylvia undata and S. melanocephala , studied one site altered by prescribed burning, five passerines ( Luscinia megarhynchos Turdus merula Parus major P. caeruleus )...
Herps, especially amphibians, are particularly susceptible to climate change, as temperature tightly controls many parameters of their biological cycle-above all, phenology. The timing herps' activity or migration period-in particular the dates first appearance in spring and breeding-and shift earlier response warming since last quarter 20th century has often been described up now a nearly monotonic trend towards phenological events. In this study, we used citizen science data...
In the Mediterranean basin, Greater Flamingos Phoenicopterus roseus constitute a metapopulation with natal and breeding dispersal among colonies. However, rate of exchange between European North African colonies remains poorly known. this paper, we document wintering flamingos in Algeria provide first post-fledging data for born Algeria. At Algeria, most ringed birds (99.4% 835 birds) originated from north-western (397 individuals France, 369 Spain, 57 Sardinia seven continental Italy), but...
A simple biochemical approach for demonstrating the presence of symbionts in deep‐sea bivalves and discriminating between thiotrophic methylotrophic symbioses is described. Correspondence analysis (CA) free amino compound composition nine bivalve species living hydrothermal vents cold seeps successfully discriminates symbiotic from nonsymbiotic ones, sulfur‐oxidizing symbiont symbionts. CA was also used to infer metabolism Bathymodiolus azoricus , B. boomerang two new Mytilid Vesicomyid...
We examined the relationship between Corsican nuthatch Sitta whiteheadi , a passerine endemic to island of Corsica and pine Pinus nigra laricio forest, its virtually exclusive habitat, currently restricted inland mountains. The prefers older stands with tall, large trees, avoids younger stands, both in breeding wintering seasons. This preference is explained by greater availability seeds from trees. Territorial adults are almost completely sedentary, trait that influenced seed hoarding...
