Assessing coastal habitats with Juniperus sp. pl. in the Iberian Peninsula and on the Balearic Islands
2021
Coastal habitats with Juniperus sp. pl. represent the mature stage in the ecological succession of dune ecosystems. Maritime junipers (Juniperus macrocarpa), prickly junipers (J. navicularis) and c...
The spread of steppe and Iranian-related ancestry in the islands of the western Mediterranean
2020
Steppe-pastoralist-related ancestry reached Central Europe by at least 2500 bc, whereas Iranian farmer-related ancestry was present in Aegean Europe by at least 1900 bc. However, the spread of these ancestries into the western Mediterranean, where they have contributed to many populations that live today, remains poorly understood. Here, we generated genome-wide ancient-DNA data from the Balearic Islands, Sicily and Sardinia, increasing the number of individuals with reported data from 5 to 66. The oldest individual from the Balearic Islands (~2400 bc) carried ancestry from steppe pastoralists that probably derived from west-to-east migration from Iberia, although two later Balearic individ…
Descripción de un nuevo limácido de Menorca (Islas Baleares): Gigantomilax (Vitrinoides) benjaminus sp. n. (Gastropoda, Pulmonata)
2008
We describe a new endemic limacid slug, Gigantomilax (Vitrinoides) benjaminus n. sp. and we compare it with the nearest species, particularly with Gigantomilax (V.) majoricensis, another Balearic endemism. Characteristic features of this new species include its small size, translucid and smooth body, and totally grey dorsum with no bands or spots. The reproductive system shows a well developed vas deferens surrounded by the distal part of prostatic gland, a thin penial retractor muscle, swollen prostate and small distal genitalia. The recent redescription of Limax majoricensis by Wiktor et al. (2007) is discussed and we consider that these authors refer to G. benjaminus n. sp., and so we de…
El macro-modelat de la costa carbonàtica de Victòria (Austràlia): paral.lelismes i diferències amb les cales baleàriques
2019
Les cales són penetracions marines, preferentment a un litoral carbonatat de caràcter tabular, arran de la inundació eustàtica d’un antic curs fluvial en la morfogènesi de les quals, de més a més del paper de la fracturació distensiva i la carstificació, també hi participen els mecanismes de col·lapse i la dinàmica litoral així com les variacions glacio-eustàtiques del nivell marí, especialment durant el Quaternari. El present treball aborda la tipologia i característiques dels elements del macro-modelat de la costa rocosa de Victòria (sud d’Austràlia) i les compara amb els antecedents i el coneixement obtingut en l’estudi de les cales de la Mediterrància occidental, principalment les de le…

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…
Chromosome numbers in plant taxa endemic to the Balearic Islands
2005
Mitotic chromosome numbers are reported from 20 vascular plant taxa that are endemic to the Balearic Islands and poorly known cytogenetically. The chromosome numbers of Arenaria grandiflora L. ssp. glabrescens (Willk.) G. Lopez & Nieto Feliner (2n = 44), Dianthus rupicola Viv. ssp. bocchoriana L. Llorens & Gradaille (2n = 30), Solenopsis minuta (L.) C. Presl. ssp. balearica (E. Wimm.) Meikle (2n = 28), Romulea asumptionis Font Quer & Garcias Font (2n = 56), Scutellaria balearica Barcelo (2n = 22) and Galium balearicum Briq. (2n = 22) have been determined for the first time. A new chromosome number was found in two populations of Helictotrichon crassifolium (Font Quer) Holub (2n = c. 98) sug…
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. …
