Résumé : Carex cespitosa L. (Cyperaceae) has been traditionally regarded as widespread in Europe, being reported from most countries. However, its distribution is currently overestimated due to the ambiguous use of the name C. cespitosa, together with frequent taxonomic confusion, mainly with the closely related C. elata All. and C. nigra (L.) Reichard. We present a critical revision of the distribution of C. cespitosa in Europe W of the former USSR, based on herbarium material and literature. We confirm the presence of the species in 19 European countries, while its occurrence is considered as doubtful in another five countries. Data pertinent to the ecology and conservation status of the species in the different countries are also provided. It is considered threatened or nearly so in at least eight countries. Hybrids with C. acuta L., C. elata and C. nigra are morphologically characterized and discussed. Although chorological revisions of the European flora are commonly considered of relatively minor scientific relevance, the situation detected by our survey of C. cespitosa reveals the importance of, and need for, these basic works for the accurate knowledge of many species, especially for subsequent works on conservation biology and biogeography.

A contribution to the knowledge of bryophytes from Sierra de Gredos (central Spain) including a reevaluation of their national conservation status / Modesto Luceño in Cryptogamie, Bryologie, 38 (3) (07/2017)

Public Citation [article]  inCryptogamie, Bryologie > 38 (3) (07/2017) . - 281-302 Titre : A contribution to the knowledge of bryophytes from Sierra de Gredos (central Spain) including a reevaluation of their national conservation status Type de document : Imprimé Auteurs : Modesto Luceño ; Carlos Cerejon ; Samuel Guerra-Cardenas ; José Ignacio Márquez-Corrro ; Victor Pineda-Labella ; Santiago Martín-Bravo (1980-) ; Marta Infante Sánchez ; Jesús Muñoz Année de publication : 2017 Article en page(s) : 281-302 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Bryophytes Résumé : Despite the significant increase of bryological studies in Spain during the last decades, some regions remain poorly studied. This is the case of Sierra de Gredos mountain range, in the Iberian Central System, which we visited in several collecting expeditions, with focus in the insufficiently explored high mountain areas. As a result, we highlight 28 taxa either by their importance in bryological conservation or because those populations are the first evidence of the taxa in the Iberian Central System. It is remarkable the presence of Kiaeria falcata, never collected previously in the Iberian Peninsula although reported in error based on K. starkei specimens, and Polytrichastrum sexangulare, known so far in the Iberian Peninsula only from the Pyrenees. Likewise, we highlight the new populations of Andreaea nivalis, Anthoceros caucasicus, Kiaeria blyttii, Meesia triquetra, and Polytrichum longisetum. The first one is reported fertile for the first time in Spain. In addition, we found 13 species listed in different threat categories whose number of populations and/or Area of Occupancy (AOO) is inconsistent with the category to that they have been assigned in Spain. Thus, four endangered species proved to be relatively common in the Central System; consequently, we propose to withdraw these species from the list of threatened bryophytes in Spain. This study highlights the urgent need to deepen into the taxonomic and chorological research of Spanish bryological biodiversity to set a solid basis on which an adequate and efficient conservation management may be performed. Finally, taxonomic and ecological comments are indicated for some species.
