Doñana's Retuerta horse

The Retuerta horse is mainly located in the Doñana National Park, specifically in the Doñana Biological Reserve, and in the Guadiamar Reserve. It counts with an approximate population of 300 horses. This specimen was used in the past by the people of Doñana as a work animal and as a means of transport, but, nowadays, this animal lives in the wild. In 2003, the population was sampled and its genetic profile and genetic distances facing other breeds were established. The genetic distance tree showed that the Retuerta horses formed a group genetically isolated from the eleven tested breeds. In addition, it was found that 31 of the specimens with biochemical markers were carriers of an allele of the esterase, the "m" allele, which was never previously described in other breeds. Furthermore, it was found in the Retuerta horses in a large proportion another allele of the esterase gene, the "L" allele, which found in a few horses around the world. informacion[at]ebd.csic.es: Calderón & Vega-Pla (2020) El caballo de las Retuertas de Doñana.

A risk assessment in Spain reveals that 30 invasive plant species are available for sale

A risk assessment in Spain reveals that 30 invasive plant species are available for sale

Horticulture is one of the main pathways of deliberate introduction of non-native plants, some of which might become invasive. Of the 914 commercial ornamental outdoor plant species sold in Spain, 700 (77%) are non-native (archaeophytes excluded) marketed species. These species were classified into six different lists based on their invasion status in Spain and elsewhere, their climatic suitability in Spain, and their potential environmental and socioeconomic impacts. Sufficient information for 270 species was available. A Priority List of eight regulated invasive species that were still available on the market is provided. Additionally an Attention List with 68 non-regulated invasive and potentially invasive species that might cause various impacts was established. To prioritise the species within the Attention List, the risk of invasion of these species was further assessed by using an adaptation of the Australian WRA protocol and the level of societal interest estimated from values of the Google Trends tool. Three other lists were proposed: A Green List of seven species with probably no potential to become invasive, a Watch List with 27 potentially invasive species with few potential impacts, and an Uncertainty List with 161 species of known status but with insufficient information to include them in any of the previous lists. For 430 (61%) of the marketed non-native plant species no sufficient information was available, which were compiled into a Data Deficient List. These findings of prohibited species for sale highlight the need for stronger enforcement of the regulations on invasive plant species in Spain. In addition, our results highlight the need for additional information on potential impacts and climate suitability of horticultural plants being sold in Spain, as insufficient information could be found to assess the invasion risk for a majority of species. informacion[at]ebd.csic.es: Bayon & Vilà (2019) Horizon scanning to identify invasion risk of ornamental plants marketed in Spain.
