40 Years of Breeding Bird Community Dynamics in a Primeval Temperate Forest (Białowieża National Park, Poland)

2015

We documented the composition and structure of the breeding bird assemblage in the primeval temperate forest of the Bialowieza National Park (BNP), during 2010-2014, and used 40 years of data to assess patterns of its diver- sity. We applied an improved version of the mapping technique (a combined mapping method) for forest birds in seven plots located in three old-growth forest types: ash-alder riverine, oak-hornbeam, and mixed coniferous. The composi- tion of the breeding avifauna and species richness remained basically unchanged. Jointly 67 (79% of 40-year total) breeding species were recorded in 2010-2014. Overall 49 (57%) of all species bred in the study plots in more than 35 years, th…

Ocean-scale connectivity and life cycle reconstruction in a deep-sea fish

2014

Author's version of an article in the journal: Canadian Journal of Fisheries and Aquatic Sciences. Also available from the publisher at: http://dx.doi.org/10.1139/cjfas-2013-0343 As human exploration and harvesting moves to the high seas, ecological understanding of the deep sea has become a priority, especially in those commercially exploited species whose life cycle, habitat use, and demographic structure remain poorly understood. Here we combine otolith trace element and stable isotope analyses with microsatellite data to investigate population structure and connectivity in the migratory deep-sea black scabbardfish (Aphanopus carbo), sampled along a latitudinal gradient spanning much of …

Simplification, not “tropicalization”, of temperate marine ecosystems under ocean warming and acidification

2021

Ocean warming is altering the biogeographical distribution of marine organisms. In the tropics, rising sea surface temperatures are restructuring coral reef communities with sensitive species being lost. At the biogeographical divide between temperate and tropical communities, warming is causing macroalgal forest loss and the spread of tropical corals, fishes and other species, termed “tropicalization”. A lack of field research into the combined effects of warming and ocean acidification means there is a gap in our ability to understand and plan for changes in coastal ecosystems. Here, we focus on the tropicalization trajectory of temperate marine ecosystems becoming coral-dominated systems…

Adaptations and Predispositions of Different Middle European Arthropod Taxa (Collembola, Araneae, Chilopoda, Diplopoda) to Flooding and Drought Condi…

2012

Simple Summary This review summarizes adaptations and predispositions of different arthropod taxa (springtails, web spiders, millipedes and centipedes) to flood and drought conditions. The main focus sis directed to arthropod species, which are living in Middle European floodplain forests and wetlands, because of the fast change of flood and drought conditions in these habitats. Furthermore the effects of the predicted regional climate change like increasing aperiodic summer flooding and decreasing winter and spring floods are also discussed. Abstract Floodplain forests and wetlands are amongst the most diverse and species rich habitats on earth. Arthropods are a key group for the high dive…

Factors influencing the distribution, abundance and nest-site selection of an endangered Egyptian vulture (Neophron percnopterus) population in Sicily

2003

Egyptian vulture (Neophrom percnopterus) breeds in Sicily and, in 22 years of monitoring, has shown a decline followed by a slight recovery. We used Generalised Linear Models to predict: (1) the distribution range, (2) the habitat selection within the range, (3) the quality (i.e., occupation rate, breeding success) of breeding sites. Some 60% of Sicily proved to be unsuitable, being either too densely forested and without cliffs for nesting, or too densely populated, along with intensive agriculture. The models converged, indicating that the pairs select a precise upland habitat where low cliffs, distant from urban areas, are surrounded by arboreal crops and Mediterranean vegetation. The va…

Typologies d'habitat et territoires, quelles représentations en 2016? Des signes pour l'émergence d'une nouvelle offre?

2017

National audience; Le XXe Siècle a été le théâtre d’importantes mutations en matière de développement urbain. A la ville pédestre, millénaire, aura succédé sur un temps très court la ville étendue à ses faubourgs desservis par les transports en commun, puis la ville périurbaine, diffuse, parfois lointaine et zonée fonctionnellement, autorisée particulièrement par la démocratisation de l’automobile (Mumford, 1964 ; Wiel, 1999). Ville et mobilité faisant système, les révolutions récentes de l’offre de mobilité ont bouleversé les formes du développement urbain, consacrant notamment la dépendance automobile (Dupuy, 1999).

Iron Age Landscape and Rural Habitat in the Edetan Territory, Iberia (4th–3rd centuries BC)

2009

This article focuses on the rural organisation and the settlement pattern of the Iberian Iron Age city of Edeta. Ongoing research into its macro-spatial organisation has revealed the existence of different functions and internal features within the settlements and their relation to a wider and more integrated space: the territory. Based on excavation and survey data, we present new questions and analytical categories in order to approach issues related to territory formation and the emergence of socio-economic complexity in the Iron Age societies of ancient eastern Iberia.

The rural dwelling of the Second Iron Age

2013

This book, resulting from a national investigation conducted by Inrap, is an analytical presentation of the rhythms of the emergence and abandonment of rural settlements during the Second Iron Age in the northern half of France. Depending on the region studied, between the 5th century BC and the 1st century AD, rural settlements were established, and have now been studied through preventative archaeological operations covering large surfaces. These studied updated our knowledge of the Gallic countryside, integrating paleobotanical, zooarchaeological and climatic data. Through systematic studies and presentations, this book offers a useful glimpse into this period, linking archaeology and hi…

Biodiversity of wood-decay fungi in Italy

2011

Abstract Current knowledge about Italian wood-decay fungi (Basidiomycota and Ascomycota) is surveyed: 1582 taxa belonging to Ascomycota (341) and Basidiomycota (1241) have been reported, including 23 species new to science of Basidiomycota described from Italy within the last five years. Evaluating diversity of wood-decay fungi can provide a more accurate estimation of species richness for fungi which are an important functional component of ecosystems. Aphyllophoroid and Ascomycota species play an important role in habitat conservation and management. Sardinia, Sicily, the Alps and the Apennines are “hot spots” for wood-decay Basidiomycota in Italy.
