Herbario UNEX, Universidad de Extremadura
The herbarium of University of Extremadura (UNEX Herbarium) is formed by 36451 specimens of vascular plants whose main origin is the autonomous region of Extremadura (Spain) and Portugal, although it also contains a smaller number of specimens from different places, including the rest of peninsular Spain, the Baleares Islands, the Macaronesian region (Canary Islands, Madeira and Azores), northwest of Africa (Morocco) and Brazil.
Established in 1986, the specimens that the herbarium of vascular plants collection of University of Extremadura (UNEX Herbarium) incorporates is the result of the work of collections and identifications by different researchers, associated with the Botany Area (Department of Plant Biology, Ecology and Earth Sciences) of the University of Extremadura. Chief amongst these individuals include; Professor Juan Antonio Devesa, founder and director of the herbarium until 2004, and Dr. Trinidad Ruiz, curator and current director of the UNEX Herbarium. Significant contributions have also been made by Professor Ana Ortega, Dr. Rafael Tormo, Dr. Josefa López, and Dr. Tomás Rodríguez. Other researchers who contributed to the growth of the UNEX Herbarium includes, Mª Carmen Viera, Jacinto Pedro Carrasco, Adolfo Muñoz, Inmaculada Montero, and Francisco Mª Vázquez. In addition, the disinterested work developed throughout time by a lot of students of the University of Extremadura, especially, Mª Luisa Navarro Pérez and Dr. Francisco Javier Valtueña.
The development of different research projects has made it possible to improve the quality of the herbarium. Among them, the numerous compilations carried out by differents members of the Botany Area in order to elaborate the first flora of the Extremadura region (Devesa 1995) or the synthesis of different taxonomic families or genera for Flora Ibérica http://www.floraiberica.org/). Additionally, 4.5% of the material comes from the purchase of part of the herbarium of Dr. J.V.C. Malato-Beliz. Limited and unpredictable funding has always pose challenge for ensuring sustained growth of the collection facility since its establishment.
98% of the total records are georeferenced. It is an active collection in continuous growth. Its data can be accessed through the GBIF data portal at http://data.gbif.org/datasets/resource/255 and http://www.eweb.unex.es/eweb/botanica/herbario/.
This paper describes the specimen associated data set of the UNEX Herbarium, with an objective to disseminate the data contained in a data set with potential users, and promote the multiple uses of the data.
Kingdoms covered include Plantae.
Includes members from the following taxa:
Acanthaceae, Aceraceae, Adiantaceae.
Specimens deposited in the UNEX Herbarium have been collected mainly from Iberian Peninsula (Spain and Portugal) northwest of Africa (Morocco) and Brazil. As indicated in Figure 4, maximum number of specimens included in the dataset are collected from Spain (31490) followed by Portugal (3488), Brazil (722) and Morocco (111) respectively. With regards to collections from Spanish provinces, Badajoz contributes 16910 specimens, followed by Cáceres (6855 specimens) and Cádiz (1012 specimens). Other sampling areas include Almería (711 specimens), Jaén (495 specimens), Málaga (411 specimens), Gerona (388 specimens), Huesca (371 specimens), León (308 specimens), Oviedo (293 specimens), Granada (290 specimens), Huelva (260 specimens) and Lérida (249 specimens). The specimens better represented in the database correspond to elements of the Mediterranean forest and/or scrubland. These specimens are developed under a seasonal climate of mild winters and hot and dry summers, with abundant rainfall in autumn and spring. Frequent in this climate are forest fires, to which the vegetation is adapted. Specimens from Brazil (except one specimen collected in the state of Santa Catarina), are collected in the state of Río Grande do Sul. This state has a humid subtropical climate and a hydrography classified into three major regions: Uruguay River Basin, Guaiba River, and Litoral.
