Peninsular Spain

Las invasiones biológicas se consideran en la actualidad como uno de los principales factores que condicionan la pérdida de biodiversidad en el planeta. En las últimas décadas, se ha incrementado el número de especies exóticas/invasoras detectadas en España. Este es el caso del picudo negro (Scyphophorus acupunctatus), un coleóptero (familia Curculionidae) originario de América, especializado en el consumo de plantas de las familias Agavaceae y Dracaenaceae. Detectado por primera vez en España en 2007, en Barcelona, ha sufrido una amplia expansión por todo el arco Mediterráneo. A partir de la recopilación de citas obtenidas de diferentes bases de datos, así como de otras obtenidas por los autores, se presenta una actualización de la distribución de esta especie para la España peninsular, discutiendo su potencial invasor. Biological invasions are considered one of the main factors conditioning the loss of biodiversity on the planet. During the last decades an increase in the number of exotic/invasive species has been detected in Spain. This is the case of the agave weevil (Scyphophorus acupunctatus), an American coleoptera (Curculionidae family) specialized in plants of the families Agavaceae and Dracaenaceae. It was detected for the first time in Spain in Barcelona in 2007. Since then it has suffered a wide expansion throughout the Iberian Mediterranean arc. From the compilation of citations obtained from different databases, as well as others obtained by the authors, an update of the distribution of this species is presented for peninsular Spain. We also discussed its invasive potential.

Preservation Conditions

Biological invasions are increasingly common worldwide due to continuous transformations that environments have been undergoing. Thus, this study aimed to catalog the exotic invasive species that occur on different environments at the Agricultural Sciences Campus from the Federal University of the São Francisco Valley, Petrolina-PE and to measure the distribution of the species diversity in the evaluated environments. The study area was initially divided into six environments. By walking around (active search) through these environments, all exotic invasive species were collected and herborized. Overall, 29 species were sampled, distributed into 16 genera and 12 families. From all catalogued species, 18 were herbs, four trees, four climbing plants and three were bushes. Regarding their origin, 13 were from African continent, one from Europe, two from Asia, two from India, one from Madagascar and four from Central America. Some species still have natural occurrence at more than one continent. The ruderal environments showed greater similarity to each other, with a percentage of exotic invasive species in common, equal or greater than 75%. This study suggests that modified (degraded) environments are enabler of biological invasions.
