Linderiella baetica Alonso & Garcia-de-Lomas 2009 (Crustacea, Branchiopoda, Anostraca): On the verge of extinction?
The 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 …
Sister species within the Triops cancriformis lineage (Crustacea, Notostraca)
301 Korn, M., Marrone, F., Perez-Bote, J. L., Machado, M., Cristo, M., Cancela da Fonseca, L. & Hundsdoerfer, A. K. (2006). Sister species within the Triops cancriformis lineage (Crustacea, Notostraca). — Zoologica Scripta , 35 , 301–322. We investigated the phylogenetic relationships among the three presently recognized subspecies of the tadpole shrimp, Triops cancriformis , using mitochondrial 16S and 12S rDNA sequences. Our results indicate that the taxon is divided into two distinct lineages. One lineage is formed of T. c. cancriformis populations and samples from northern Spain that had been classified as T. c. simplex in the most recent literature. The second lineage comprises all pop…
