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…
Archaeogenetics and Landscape Dynamics in Sicily during the Holocene: A Review
2021
The Mediterranean islands and their population history are of considerable importance to the interpretation of the population history of Europe as a whole. In this context, Sicily, because of its geographic position, represents a bridge between Africa, the Near East, and Europe that led to the stratification of settlements and admixture events. The genetic analysis of extant and ancient human samples has tried to reconstruct the population dynamics associated with the cultural and demographic changes that took place during the prehistory and history of Sicily. In turn, genetic, demographic and cultural changes need to be understood in the context of the environmental changes that took place…
The first colonization of Ibiza and Formentera (Balearic Islands, Spain): Some more islands out of the stream?
1995
Abstract The Balearic Islands, off the east coast of Spain, have provided a focus of interest in investigations of the earliest colonization of the Mediterranean islands, because of the relatively late date of their oldest sites. Mallorca was visited in the fifth millennium BC and inhabited by the third, and Menorca was colonized during the closing centuries of the third millennium; this therefore makes Ibiza and Formentera special cases of isolation, since they were evidently not occupied until about 2000 BC and moreover were essentially deserted between roughly the thirteenth and seventh centuries BC. The paper presents all the currently available data relevant to this question, particula…
Performances of GPM satellite precipitation over the two major Mediterranean islands
2018
Reliable and accurate precipitation measurement or estimation is crucial for disaster monitoring and water resource management. However, obtaining accurate high-resolution precipitation fields is still a challenging task for scientists and practitioners, especially in the poorer region of the world. Nowadays the scientific community expects significant improvements in precipitation monitoring by the continuous technological evolution of satellite-rainfall estimate systems which are able to produce data with global coverage and thus can provide low-cost information even in scarcely populated areas or places where for economic reasons ground measures are missing. The most recent satellite mis…
Optical Remote Sensing in Urban Environments
2016
International audience; Cities today face a variety of issues: attractiveness and economic development, living conditions and urban redevelopment, the quality of life of citizens and the environmental conditions of the urban system as a whole. These challenges reflect the situations in urban territories where the economic development and population growth required for stabilizing the urban system come into conflict with the promotion of esthetic urban improvements appropriate for social cohesion and ensuring the safety of users while guaranteeing a reduction of the environmental impact caused by urban spread [WGI 14, WEB 15, MAC 07, WIL 11]. The process of urbanization, which has significan…
Helianthemum scopulicolum (Cistaceae), a new species from Majorca (Balearic Islands, Spain)
1999
Rupicolous plants coming from a single Balearic locality are described as a new species, Helianthemum scopulicolum. The plant is diploid (2n=20) and belongs to Helianthemum subgenus Helianthemum sect. Helianthemum. On morphological grounds, Helianthemum scopulicolum is related to some members of the H. apenninum aggregate, notably H. apenninum s.l., H. asperum and H. violaceum. However, the new species can be distinguished on the basis of leaves green, shining, glabrescent on the adaxial surface, deciduous short bracts, glabrescent inner sepals lacking long setae and pink-purple flowers.
Euphorbia Nurae P. Fraga & Rosselló (Euphorbiaceae), a New Species from Minorca (Balearic Islands)
2011
Abstract FRAGA-ARGUIMBAU, P. & J. A. ROSSELLO (2011). Euphorbia nurae P. Fraga & Rossello (Euphorbiaceae), a new species from Minorca (Balearic Islands). Candollea 66: 181–190. In English, English and French abstracts. Euphorbia nurae P. Fraga & Rossello (Euphorbiaceae sect. Cymatospermum (Prokh.) Prokh.) is described as a new species from coastal sites of Minorca (Balearic Islands). Morphological features suggest that Euphorbia exigua L., Euphorbia dracunculoides Lam. and Euphorbia sulcata Loisel. are the most closely related taxa, but the new species can be easily discriminated by several morphological characters.
Metric discrimination and distribution of the species of Crocidura occuring in Tunisia
1992
A recent paper on the occurrence of the genus Crocidura in Tunisia reports a single specimen identified as C. suaveolens. Therefore a third species, besides C. russula and C. whitakeri would occur in the country. However, the presence of C. suaveolens in North-Africa is controversial and was recently ruled out from the other Maghrebi countries (Algieria and Morocco). During the period 1989-90, 71 specimens of shrews were collected from owls pellets or trapped at Tunisian 12 sites. This material was measured and studied both by classic morphometric and multivariate methods (Fuzzy test, Principal Coordinate Analysis and Generalized Procrustes Analysis), considering also reference samples (C. …
<strong>Nomenclatural types of <em>Hieracium</em> (Asteraceae) species described from the Balearic Islands (Spain) and several rela…
2021
A nomenclatural revision of the genus Hieracium in the Balearic Islands (Spain) is presented and the typification of five names: H. aragonense Scheele, H. balearicum Arvet‑Touvet, H. elisaeanum Arvet-Touvet ex Willkomm, H. majoricanum Arvet-Touvet and H. microscapum Arvet-Touvet, is discussed. The names are lectotypified using specimens preserved at COI, GRM, and P herbaria. Several comments for the names H. cataractarum Arvet-Touvet & Huter and H. praecox subsp. brachypus Freyn in Porta & Rigo are also provided.
