  abstract  = {Laura Pavesi, Elvira De Matthaeis, Ralph Tiedemann, and Valerio Ketmaier (2011) Temporal population genetics and COI phylogeography of the sandhopper Macarorchestia remyi (Amphipoda: Talitridae). Zoological Studies 50(2): 220-229. In this study we assessed levels of genetic divergence and variability in 208 individuals of the supralittoral sandhopper Macarorchestia remyi, a species strictly associated with rotted wood stranded on sand beaches, by analyzing sequence polymorphisms in a fragment of the mitochondrial DNA (mtDNA) gene coding cytochrome oxidase subunit I (COI). The geographical distribution and ecology of the species are poorly known. The study includes 1 Tyrrhenian and 2 Adriatic populations sampled along the Italian peninsula plus a single individual found on Corfu Is. (Greece). The Tyrrhenian population was sampled monthly for 1 yr. Genetic data revealed a deep phylogeographic break between the Tyrrhenian and Adriatic populations with no shared haplotypes. The single individual collected on Corfu Is. carried the most common haplotype found in the Tyrrhenian population. A mismatch analysis could not reject the hypothesis of a sudden demographic expansion in almost all but 2 monthly samples. When compared to previous genetic data centered on a variety of Mediterranean talitrids, our results place M. remyi among those species with profound intraspecific divergence (sandhoppers) and dissimilar from beachfleas, which generally display little population genetic structuring.},

  abstract  = {Chirocephalus ruffoi is a fairy shrimp endemic to the Italian peninsula, where it is known only from thirteen high mountain locations. Twelve of these are in the Northern Apennines while the thirteenth is about 700 km away in the Calabrian Apennines (Southern Italy). We quantified degree of genetic divergence within the species by sequencing a fragment of the mitochondrial DNA encoding for Cytochrome Oxidase I. We then combined genetic data with the re-analysis of two different datasets on the morphometrics of the resting eggs (cysts) produced by the species as an adaptation to survive seasonal droughts. Genetic data revealed profound divergence; we identified four clusters of haplotypes within the species phylogeography, three in the Northern Apennines and one in the Calabrian Apennines with most of the genetic variation (a parts per thousand 70\%) being apportioned among haplogroups. We found high variability in cyst morphometrics, especially in cyst size and height of the spines ornamenting the surface. Genetic and morphometric data are decoupled suggesting that cyst morphology is either under selection or a plastic trait. We, therefore, caution against using cyst morphology for taxonomic purposes in anostracans.},
