Phylogenomics of the Hyalella Amphipod Species-Flock of The
www.nature.com/scientificreports OPEN Phylogenomics of the Hyalella amphipod species‑fock of the Andean Altiplano Francesco Zapelloni1,3, Joan Pons2,3, José A. Jurado‑Rivera1, Damià Jaume2 & Carlos Juan1,2* Species diversifcation in ancient lakes has enabled essential insights into evolutionary theory as they embody an evolutionary microcosm compared to continental terrestrial habitats. We have studied the high‑altitude amphipods of the Andes Altiplano using mitogenomic, nuclear ribosomal and single‑ copy nuclear gene sequences obtained from 36 Hyalella genomic libraries, focusing on species of the Lake Titicaca and other water bodies of the Altiplano northern plateau. Results show that early Miocene South American lineages have recently (late Pliocene or early Pleistocene) diversifed in the Andes with a striking morphological convergence among lineages. This pattern is consistent with the ecological opportunities (access to unoccupied resources, initial relaxed selection on ecologically‑ signifcant traits and low competition) ofered by the lacustrine habitats established after the Andean uplift. Lakes with an uninterrupted history of more than 100,000 years (ancient lakes) may be considered as natural laboratories for evolutionary research as they constitute hotspots of aquatic animal speciation and phenotypic diversity1. Changes in lake size and episodes of desiccation are considered to be critical factors in the speciation and extinction of lake faunas, with the creation of new habitats afer lake expansions as the primary driver of intra-lake diversifcation2–4. For instance, cichlid radiations in the East African Lakes seem to have been trig- gered by lake expansions afer periods of intense desiccation, with the surviving species flling up empty niches afer lake reflling2. -
BORON of Aquatic Life
Canadian Water Quality Guidelines for the Protection BORON of Aquatic Life oron (CAS Registry Number 7440-42-8) is The wet deposition of boron over the continents is ubiquitous in the environment, occurring estimated to be approximately 0.50 Tg B/yr, where Bnaturally in over 80 minerals and constituting rainwater from continental sites contains less boron 0.001% of the Earth’s crust (U.S. EPA, 1987). The when compared to boron from coastal and marine sites chemical symbol for Boron is B with an atomic weight (Park and Schlesinger, 2002).Natural weathering of 10.81 g mol-1 (Budavari et al., 1989; Weast, 1985; (chemical and mechanical) of boron-containing rocks is Lide, 2000; Clayton and Clayton, 1982; Sax, 1984; a major source of boron compounds in water Windholz, 1983; Moss and Nagpal, 2003). Boron is not (Butterwick et al., 1989) and on land (Park and found as a free element in nature. Schlesinger, 2002). The amount of boron released into the aquatic environment varies greatly depending on the Sources to the environment: The highest concentrations surrounding geology. Boron compounds also are of boron are found in sediments and sedimentary rock, released to water in municipal sewage and in waste particularly in clay rich marine sediments. The high waters from coal-burning power plants, irrigation, boron concentration in seawater (4.5 mg B L-1), ensures copper smelters and industries using boron (ATSDR, that marine clays are rich in boron relative to other rock 1992; Howe, 1998). With respect to Canadian types (Butterwick et al., 1989). The most significant wastewater discharges, a literature review was source of boron is seasalt aerosols, where annual input conducted to characterize the state of knowledge of of boron to the atmosphere is estimated to be 1.44 Tg B municipal effluent (Hydromantis Inc., 2005). -

Cladistic Revision of Talitroidean Amphipods (Crustacea, Gammaridea), with a Proposal of a New Classification
CladisticBlackwell Publishing, Ltd. revision of talitroidean amphipods (Crustacea, Gammaridea), with a proposal of a new classification CRISTIANA S. SEREJO Accepted: 8 December 2003 Serejo, C. S. (2004). Cladistic revision of talitroidean amphipods (Crustacea, Gammaridea), with a proposal of a new classification. — Zoologica Scripta, 33, 551–586. This paper reports the results of a cladistic analysis of the Talitroidea s.l., which includes about 400 species, in 96 genera distributed in 10 families. The analysis was performed using PAUP and was based on a character matrix of 34 terminal taxa and 43 morphological characters. Four most parsimonious trees were obtained with 175 steps (CI = 0.617, RI = 0.736). A strict consensus tree was calculated and the following general conclusions were reached. The superfamily Talitroidea is elevated herein as infraorder Talitrida, which is subdivided into three main branches: a small clade formed by Kuria and Micropythia (the Kurioidea), and two larger groups maintained as distinct superfamilies (Phliantoidea, including six families, and Talitroidea s.s., including four). Within the Talitroidea s.s., the following taxonomic changes are proposed: Hyalellidae and Najnidae are synonymized with Dogielinotidae, and treated as subfamilies; a new family rank is proposed for the Chiltoniinae.

Temperature Exposure and Possible Thermoregulation Strategies in the Titicaca Water Frog Telmatobius Culeus, a Fully Aquatic Frog of the High Andes

J. Janssens1 1Laboratory of Animal Nutrition, Ghent University, 9820 Merelbeke, Belgium 2Natural History Museum Alcide d’Orbigny, Cochabamba, Bolivia ABSTRACT: Temperature has an important effect on amphibians, influencing virtually all physio - logical systems. Thermoregulation is used to manage unfavourable thermal conditions, but has been poorly studied in aquatic amphibians, and no information is available for adult aquatic anu- rans. We studied the temperatures to which the Critically Endangered and high Andean fully aquatic Titicaca water frog Telmatobius culeus is exposed and investigated possible thermoregu- lation strategies of the species in the wild. We measured water temperature in different seasons, microhabitats and depths at which T. culeus is most abundant. We established transects to obtain population densities and activity patterns of the species during the day. Seasonal and daily tem- perature variations as well as temperature variations among depths and microhabitats were noted. These variations were associated with densities of visible T. culeus, where adult densities were higher at depths with more stable temperatures. T. culeus behaviour associated with thermo - regulation strategies in the aquatic habitat included depth selection and movement of individuals between different microhabitats. Selection of microhabitat depended on the temperature at a site and the hour of the day. These results indicate possible behavioural thermoregulation strategies such as movement to different sites or basking used by a highly specialized amphibian, and pro- vide insights into how aquatic benthic organisms use strategies for thermoregulation in aquatic heterogeneous environments. -

In this report we describe a new species of Hyalella from the Atlantic Forest of the Misiones province, Argentina. Keywords Hyalella, taxonomy, freshwater amphipods, novel-species description, Argentina Introduction The genus Hyalella includes approximately 70 valid species distributed in only the Americas (Baldinger 2004, WoRMS 2014). The hyalellids inhabit different freshwa- ter environments, associated with either the bottom sediments (benthic fauna) or the aquatic vegetation (Poi de Neiff 1992), where these amphipods constitute a funda- mental link in the transfer of matter and energy in those ecosystems (Casset et al.
