Given that both the biotic and abiotic parameters of salt ponds within the Aveiro’s AUTHOR'S PROOF salinas complex (Portugal) presently occupied by A. franciscana have already been thoroughly characterised (Vieira and Bio Journal of Sea Research 65:293–303, 2011), we will compare the same variables to those measured in an artisanal salina from the same complex, where native Artemia still occurs. Since there is no indication of salt ponds where both the native and invasive species co-occur, we hypothesise that explicit differences in environmental factors (e.g. salinity, temperature, pH, alkalinity, dissolved oxygen availability or nutrient concentrations) would help justify the observed distribution pattern of both Artemia species. 55 Keywords Artemia - Salina - Ecology - Biological invasions separated by ' - ' 56 Foot note information AUTHOR'S PROOF JrnlID 13157_ArtID 338_Proof# 1 - 20/09/2012 Wetlands DOI 10.1007/s13157-012-0338-0 1 3 ARTICLE 2 4 Surviving an Invasion: Characterization of One 5 of the Last Refugia for Artemia Diploid Parthenogenetic Strains 79 Carolina M.

  • Invertebrate Animals (Metazoa: Invertebrata) of the Atanasovsko Lake, Bulgaria
    Historia naturalis bulgarica, 22: 45-71, 2015 Invertebrate Animals (Metazoa: Invertebrata) of the Atanasovsko Lake, Bulgaria Zdravko Hubenov, Lyubomir Kenderov, Ivan Pandourski Abstract: The role of the Atanasovsko Lake for storage and protection of the specific faunistic diversity, characteristic of the hyper-saline lakes of the Bulgarian seaside is presented. The fauna of the lake and surrounding waters is reviewed, the taxonomic diversity and some zoogeographical and ecological features of the invertebrates are analyzed. The lake system includes from freshwater to hyper-saline basins with fast changing environment. A total of 6 types, 10 classes, 35 orders, 82 families and 157 species are known from the Atanasovsko Lake and the surrounding basins. They include 56 species (35.7%) marine and marine-brackish forms and 101 species (64.3%) brackish-freshwater, freshwater and terrestrial forms, connected with water. For the first time, 23 species in this study are established (12 marine, 1 brackish and 10 freshwater). The marine and marine- brackish species have 4 types of ranges – Cosmopolitan, Atlantic-Indian, Atlantic-Pacific and Atlantic. The Atlantic (66.1%) and Cosmopolitan (23.2%) ranges that include 80% of the species, predominate. Most of the fauna (over 60%) has an Atlantic-Mediterranean origin and represents an impoverished Atlantic-Mediterranean fauna. The freshwater-brackish, freshwater and terrestrial forms, connected with water, that have been established from the Atanasovsko Lake, have 2 main types of ranges – species, distributed in the Palaearctic and beyond it and species, distributed only in the Palaearctic. The representatives of the first type (52.4%) predomi- nate. They are related to the typical marine coastal habitats, optimal for the development of certain species.

Klaine, Committee Chair Dr. David Brune Dr. Pu-Chun Ke Dr. Julia Sharp ABSTRACT Plastic pollution constitutes a threat to marine wildlife because of the deleterious impacts ranging from entanglement to ingestion of plastic debris. However, knowledge regarding the impacts of fragmented plastics into micron sizes and their interaction with other toxicants in the marine environment is still limited. In the present study the impact of polystyrene microspheres, 3 µm in diameter, upon toxicity of phenol to the brine shrimp Artemia was investigated in acute toxicity tests. The brine shrimp are employed as a model organism in marine toxicity tests. Phenol is a hydrophobic compound used as an intermediate resin discharged to the environment.

  • Adaptive Significance of Polyploidy in Brine Shrimp (Artemia Parthenogenetica) Redacted for Privacy Abstract Approved
    AN ABSTRACT OF THE THESIS OF Lei Zhanq for the degree of Doctor of Philosophy in Zoology, presented on June 10, 1993. Title: Adaptive Significance of Polyploidy in Brine Shrimp (Artemia parthenogenetica) Redacted for Privacy Abstract approved To explore the adaptive significance of polyploidy in animals, I have investigated effects of polyploidy on physiological, life history and genetic characteristics, and geographic distributions in brine shrimp Artemia parthenogenetica. Based on laboratory studies of sympatric diploids and polyploids in three populations collected from China, Italy and Spain, I found that polyploid Artemia were more resistant to temperature changes than diploids. At optimal temperature and commonly used salinity (25°C, 90ppt), diploids had much higher higher fecundity and faster developmental rates than their sympatric polyploids. Polyploids had better reproductive performance than sympatric diploids at high temperature and low salinity (31 °C, 30 ppt) which correspond to marginal environmental conditions. My electrophoretic results show that genetic divergence has occurred between polyploids and diploid progenitors; some alleles occurred only in diploids, while others were restricted to polyploids. My literature review reveals that in the Old World, below 25°N latitude, all Artemia populations are polyploids, while in temperate regions (between 35- 45°N) ,diploids are the most common cytotype. Differences in relative fitness, latitudinal distributions and environmental conditions are considered for Chinese diploid and polyploid Artemia. I suggest that Artemia's habitats gradually become marginal southward along the China coast, and that the more southern distribution of polyploids along the China coast may be a result of combined effect of low salinity and high temperatures, rather than a result of temperature adaptation only.

LC50 values were calculated and differences in body growth were recorded after 24, 48, and 72 h of exposure to the toxicants. The results indicated that BPA had lower toxicity than SDS. Development of the nauplii was clearly influenced by duration of exposure. Growth inhibition was detected for both toxicants. Abnormal growth of the central eye of several Artemia nauplii after 72 h of exposure to BPA was also detected. Our results indicate that growth inhibition could be used as a valid endpoint for toxicity studies. Keywords: acute toxicity; sodium dodecyl sulfate; bisphenol a; bioassays; LC50; probit analysis 1.

The taxonomic identity of these new populations was determined based upon: i) an analysis of the variation in the caudal gene, ii) morphology of the penis and frontal knob of male specimens using scanning electronic microscopy (SEM) and iii) a principal coordinate analysis of selected biometric traits. This analysis showed that all French gonochoristic populations of Artemia were comprised of the New World species A. franciscana (Kellogg, 1906) and not the Mediterranean native species, A. salina. As well, the parthenogenetic populations of Artemia in France are being rapidly replaced populations by the North America A. franciscana.

Karen López-Estrada1, Paula Carolina Rodríguez-Flores1,3 and Mario García-París1 1 Museo Nacional de Ciencias Naturales (MNCN-CSIC), Madrid, Spain 2 Fundación Global Nature, Las Rozas, Madrid, Spain 3 Centre d’Estudis Avançats de Blanes (CEAB-CSIC), Blanes, Girona, Spain ABSTRACT High morphological plasticity in populations of brine shrimp subjected to different environmental conditions, mainly salinity, hindered for centuries the identification of the taxonomic entities encompassed within Artemia. In addition, the mismatch between molecular and morphological evolution rates complicates the characterization of evolutionary lineages, generating taxonomic problems. Here, we propose a phylogenetic hypothesis for Artemia based on two new complete mitogenomes, and determine levels of congruence in the definition of evolutionary units using nuclear and mtDNA data. We used a fossil of Artemia to calibrate the molecular clock and discuss divergence times within the genus. The hypothesis proposed herein suggests a more recent time frame for lineage splitting than previously considered. Phylogeographic analyses were performed using GenBank available mitochondrial and nuclear markers.

  • Prey Interactions Between Native Brine Shrimp Artemia Parthenogenetica and the Alien Boatman Trichocorixa
    Predator–prey interactions between native brine shrimp Artemia parthenogenetica and the alien boatman Trichocorixa verticalis: influence of salinity, predator sex, and size, abundance and parasitic status of prey Vanessa Ce´spedes, Marta I. Sa´nchez and Andy J. Green Department of Wetland Ecology, Don˜ana Biological Station, Seville, Spain ABSTRACT Trichocorixa verticalis (T. verticalis), native to North America and the Caribbean islands, is an invasive waterboatman species (Corixidae) in the southwest of the Iberian Peninsula. Previous studies in the native range have suggested that predation by T. verticalis can regulate the abundance of Anostracan and Cladoceran zooplankton in saline ecosystems, causing increases in phytoplankton through a trophic cascade. In this experimental study, we tested the predator–prey relationship between the native brine shrimp Artemia parthenogenetica, and T. verticalis from the Odiel salt ponds in SW Spain. In three experiments, we investigated (1) the effects of Artemia life stage (metanauplii, juveniles, and adults), (2) abundance (three, six, and 12 adult Artemia) and (3) parasitic status (Artemia infected with avian cestodes or uninfected) on predation rates by T. verticalis. We also considered how predation rates in all three experiments were influenced by the sex of T. verticalis and by - different salinities (25 and 55 g l 1). Experiment 1 showed that predation rates were highest for metanauplii, possibly because their photophilic behavior makes them Submitted 2May2017 more prone to predation. In Experiment 2, we found that predation rate was higher Accepted 17 June 2017 for female T. verticalis and the higher salinity, although the strength of the sex effect Published 11 July 2017 varied between treatments.

    Sustainability, Agri, Food and Environmental Research 3(4), 2015: 59-65 59 ISSN: 0719-3726 On a parthenogenetic population of Artemia (Crustacea, Branchiopoda) from Algeria (El-Bahira, Sétif) Mounia Amarouayache*1, Naim Belakri 2 1-Marines Bioressources Laboratory, Marine Sciences department, Faculty of Sciences, Annaba University Badji Mokhtar, Annaba 23000, Algeria 2- Direction de la Pêche et des Ressources Halieutiques (Sétif) *corresponding author e.mail: [email protected] Abstract The brine shrimp Artemia is a small crustacean of hypersaline lakes which is commonly used in larviculture. The parthenogenetic population of Artemia from El-Bahira Lake (10 ha area), situated in the High Plateaus of Northeastern Algeria (1034 m alt), has been characterized and surveyed during two hydroperiods of 2009 and 2013. Contrary to other known parthenogenetic populations, which develop in hot seasons and reproduce by ovoviviparity, Artemia from El-Bahira was found to develop only in cold seasons (winter and spring), Àv ]( Z ol }•v[ Ç ]v •µuu.
