- Defining the importance of landscape metrics for large branchiopod biodiversity and conservation: the case of the Iberian Peninsula and Balearic IslandsPublication . Sala, Jordi; Gascon, Stephanie; Cunillera-Montcusi, David; Alonso, Miguel; Amat, Francisco; Cancela Da Fonseca, Luís; Cristo, M.; Florencio, Margarita; Garcia-de-Lomas, Juan; Machado, Margarida; Rosa Miracle, Maria; Miro, Alexandre; Luis Perez-Bote, Jose; Lluis Pretus, Joan; Prunier, Florent; Ripoll, Javier; Rueda, Juan; Sahuquillo, Maria; Serrano, Laura; Ventura, Marc; Verdiell-Cubedo, David; Boix, DaniThe deficiency in the distributional data of invertebrate taxa is one of the major impediments acting on the bias towards the low awareness of its conservation status. The present study sets a basic framework to understand the large branchiopods distribution in the Iberian Peninsula and Balearic Islands. Since the extensive surveys performed in the late 1980s, no more studies existed updating the information for the whole studied area. The present study fills the gap, gathering together all available information on large branchiopods distribution since 1995, and analysing the effect of human population density and several landscape characteristics on their distribution, taking into consideration different spatial scales (100 m, 1 km and 10 km). In overall, 28 large branchiopod taxa (17 anostracans, 7 notostracans and 4 spinicaudatans) are known to occur in the area. Approximately 30% of the sites hosted multiple species, with a maximum of 6 species. Significant positive co-occurring species pairs were found clustered together, forming 4 different associations of large branchiopod species. In general, species clustered in the same group showed similar responses to analysed landscape characteristics, usually showing a better fit at higher spatial scales.
- Distinctive genetic signatures of two fairy shrimp species with overlapping ranges in Iberian temporary pondsPublication . Lopes Da Cunha, Regina; Sala, Jordi; Machado, Margarida; Boix, Dani; Madeira, Celine; Madeira, Pedro M.; Cristo, Margarida; Cancela Da Fonseca, Luís; Castilho, RitaTemporary lentic water bodies host biotic assemblages adapted to the transient nature of these freshwater habitats. Fairy shrimps (Crustacea, Branchiopoda, Anostraca) are one of the most important biological components of these unique environments and have a fossil record dating back to the Middle Jurassic (>150 million years). Some anostracan species show a geographically restricted distribution, whereas others are widely dispersed. We aimed to investigate the relationship between different geographic extents and patterns of genetic structure in species of Anostraca. Following this objective, we selected two species with contrasting ranges but overlapping geographic distributions and similar life-history traits in the study area. We analysed additional information that, from an ecological (e.g. egg-bank, niche breadth, and pond connectivity) and evolutionary (e.g. crown-group age of each species) perspective, may explain the obtained phylogeographic patterns. Between 2005 and 2018, we sampled two species of fairy shrimps (309 specimens of Branchipus cortesi and 264 specimens of Tanymastix stagnalis) from 53 temporary ponds of Portugal. We added five other locations from Spain and France to include other European locations for T. stagnalis. Additionally, we also sampled Branchipus schaefferi from two temporary water bodies (Spain and Morocco) to include in the dating analysis. Reconstructed phylogenies based on mitochondrial sequence data indicate the existence of deeply divergent clades with an unequivocal phylogeographic structure in T. stagnalis and shallower divergences in B. cortesi with a less clear geographic correspondence. We found evidence of frequent local and rare long-distance dispersal events in both species and limited intermediate dispersal, which was more common in B. cortesi. A Bayesian dating analysis using the Branchiopoda fossil record estimated the age of the most recent common ancestors of T. stagnalis and B. cortesi at 32.4 and 12.8 million years, respectively. Haplotype accumulation curves indicated that only a portion of the genetic composition of the species was sampled on each hydroperiod and showed the existence of large, genetically diverse egg banks that remain in the soil. These egg banks represent a genetic reservoir that guarantees the survival of the species because active populations from different hydroperiods may be genetically different and adapt to a changing environment. We hypothesise that the contrasting phylogeographic patterns displayed by the two fairy shrimp species may result from: (1) the earlier age of the most recent common ancestor of T. stagnalis, as older species have more time to accumulate mutations and, thus, are expected to exhibit higher genetic differentiation among populations; (2) slight differences in adult behaviour, life-history traits and cyst morphologies of T. stagnalis and B. cortesi favouring different animal dispersal vectors with distinct dispersal abilities. Therefore, phylogeographic patterns may be explained by both evolutionary and ecological processes, which operate in different time scales.

Horizon Scanning (HS), defined as an exploration of potential threats, is considered a fundamental component of IAS management. By combining scientific knowledge on taxa with expert opinion, we identified the most relevant aquatic IAS in the Iberian Peninsula, i.e., those with the greatest geographic extent (or probability of introduction), severe ecological, economic and human health impacts, greatest difficulty and acceptability of management. We highlighted the 126 most relevant IAS already present in Ibe-rian inland waters (i.e., Concern list) and 89 with a high probability of being introduced in the near future (i.e., Alert list), of which 24 and 10 IAS, respectively, were considered as a management priority after receiving the highest scores in the expert assessment (i.e., top-ranked IAS). In both lists, aquatic IAS belonging to the four thematic groups (plants, freshwater invertebrates, estuarine invertebrates, and vertebrates) were identified as having been introduced through various pathways from different regions of the world and classified according to their main functional feeding groups. Also, the latest update of the list of IAS of Union concern pursuant to Regulation (EU) No 1143/2014 includes only 12 top-ranked IAS identified for the Iberian Peninsula, while the national lists incorporate the vast majority of them. This fact underlines the great importance of taxa prioritisation exercises at biogeographical scales as a step prior to risk anal-yses and their inclusion in national lists. This HS provides a robust assessment and a cost-effective strategy for decision -makers and stakeholders to prioritise the use of limited resources for IAS prevention and management. Although ap-plied at a transnational level in a European biodiversity hotspot, this approach is designed for potential application at any geographical or administrative scale, including the continental one.
- How threatened are large branchiopods (Crustacea, Branchiopoda) in the Iberian Peninsula?Publication . Garcia-de-Lomas, Juan; Sala, Jordi; Barrios, Violeta; Prunier, Florent; Camacho, Antonio; Machado, Margarida; Alonso, Miguel; Korn, Michael; Boix, Dani; Hortas, Francisco; Garcia, Carlos M.; Serrano, Laura; Munoz, GonzaloThe Iberian Peninsula harbours 24 taxa of native large branchiopods (LBs). Most of them inhabit Mediterranean temporary ponds, which are priority habitats under the EU Habitats Directive. In this work, Iberian LBs were evaluated using IUCN Red List criteria based on geographic range (extent of occurrence, area of occupancy, number of locations, habitat fragmentation and expected decline). Our results show that 46% of the Iberian LBs are threatened: four taxa should be considered as Critically Endangered (Linderiella baetica, Triops emeritensis, Cyzicus tetracerus and Leptestheria mayeti), three taxa fall under the category Endangered (Artemia salina, Tanymastigites lusitanica and Triops vicentinus) and four species (Artemia sp. parthenogenetic strains, Branchinecta orientalis, Lepidurus apus and Triops gadensis) are Vulnerable. Two species (Phallocryptus spinosus, and Maghrebestheria maroccana) are considered Near Threatened. Our results highlight the worrying risk of extinction of Iberian LBs at the regional level, mainly related to the disappearance and degradation of their habitats and the relatively low degree of habitat protection. For Iberian endemic species, this evaluation is also valid at the global level and gives strong support for their inclusion in the IUCN Red List.
- Linderiella baetica Alonso & Garcia-de-Lomas 2009 (Crustacea, Branchiopoda, Anostraca): On the verge of extinction?Publication . Garcia de Lomas, Juan; Garcia, Carlos M.; Hortas, Francisco; Prunier, Florent; Boix, Dani; Sala, Jordi; Leon, David; Serrano, Laura; Prenda, José; Diego Gilbert, Juan; Guerrero, Francisco J.; Marrone, Federico; Sahuquillo, Maria; Camacho, Antonio; Olmo, Carla; Rosa Miracle, Maria; Zamora-Munoz, Carmen; Mura, Graziella; Machado, Margarida; Sanchez, Inigo; Angel Galvez, José; Florencio, Margarita; Luis Perez-Bote, José; Alonso, MiguelThe province of Cadiz (South of Spain) hosts the only known locality in the world of Linderiella baetica Alonso & Garcia-de-Lomas 2009 (Anostraca). In this paper, the geographical distribution of the species based on published sampling data focused on large branchiopods and temporary pools in Andalusia and the entire Iberian Peninsula is assessed. The current situation is summarized based on the threats to their survival, which are mainly related to habitat alteration. In the Iberian Peninsula, at least 1,648 bodies of water (about 720 in Andalusia) have been explored. Prevalence data suggest that L. baetica is a rare species (localities with presence / sample locations = 6.07 . 10-4). The application of the IUCN (2012) criteria suggests that L. baetica is a threatened species, catalogued as "critically endangered". Several emergency solutions such as translocation of individuals or their propagules to newly created ponds and to sustain the efforts of exploration have been proposed. However, conservation of the species in the current circumstances it is not considered viable if the natural habitat remains unprotected. The legal protection of L. baetica is proposed.
- A multi-taxa assessment of aquatic non-indigenous species introduced into Iberian freshwater and transitional watersPublication . Zamora-Marín, Jose M.; Ruiz-Navarro, Ana; Oficialdegui, Francisco J.; Anastácio, Pedro M.; Miranda, Rafael; García-Murillo, Pablo; Cobo, Fernando; Ribeiro, Filipe; Gallardo, Belinda; García-Berthou, Emili; Boix, Dani; Medina, Leopoldo; Morcillo, Felipe; Oscoz, Javier; Guillén, Antonio; Herrero-Reyes, Antonio A.; Aguiar, Francisca C.; Almeida, David; Arias, Andrés; Ayres, César; Banha, Filipe; Barca, Sandra; Biurrun, Idoia; Cabezas, M.

The Iberian Peninsula comprises an exceptionally biodiverse Mediterranean region with a high number of threatened and endemic aquatic species, most of them strongly impacted by biological invasions. Following a structured approach that combines a systematic review of available information and expert opinion, we provide a comprehensive and updated multi-taxa inventory of aquatic NIS (fungi, macroalgae, vascular plants, invertebrates and vertebrates) in Iberian inland waters. Moreover, we assess overall patterns in the establishment status, in-troduction pathways, native range and temporal introduction trends of listed NIS. In addition, we discuss the legal coverage provided by both national (Spanish and Portuguese) and European NIS regulations. We inventoried 326 aquatic NIS in Iberian inland waters, including 215 established, 96 with uncertain estab-lishment status and 15 cryptogenic taxa. Invertebrates (54.6%) and vertebrates (24.5%) were the groups with the highest number of NIS, with Arthropoda, Mollusca, and Chordata being the most represented phyla. Recorded NIS originated from diverse geographic regions, with North and South America being the most frequent. Vertebrates and vascular plants were mostly introduced through intentional pathways (i.e. release and escape), whereas invertebrates and macroalgae arrived mostly through unintentional ways (i.e. contaminant or stowaway). Most of the recorded NIS were introduced in Iberian inland waters over the second half of the 20th century, with a high number of NIS introductions being reported in the 2000s. While only 8% of the recorded NIS appear in the European Union list of Invasive Alien Species of Union concern, around 25% are listed in the Spanish and Portuguese NIS regulations. This study provides the most updated checklist of Iberian aquatic NIS, meeting the requirements set by the EU regulation and providing a baseline for the evaluation of its application. We point out the need for coordinated transna-tional strategies to properly tackle aquatic invasions across borders of the EU members.
