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.

2019 Abstracts
We are delighted EDITORIAL to welcome the worldwide yeast community in Gothenburg for ICYGMB2019! The “International Yeast Conferences” started in the 1960s with a handful of delegates and since then have become THE most important event in yeast research. Now the yeast meeting to returns to Gothenburg. Many yeast researchers still remember the meeting in 2003 with over 1,100 delegates, a truly memorable event. The Life Sciences are changing, and yeast research remains at their forefront. Advancements in genome sequencing and genome editing just make yeast more exciting as model organism in basic cell biological research, genome evolution and as a tool for synthetic biology and biotechnology. One of the most important reasons for the enormous success of yeast research lies in the unique character of the international yeast research community. No other community employs such a free exchange and access to information and research tools. Nor has any other community had the ability to build – even intercontinental – consortia of critical mass to tackle large‐scale projects, such as in sequencing the first eukaryotic genome or the first comprehensive yeast knockout library. Yeast2019 is the meeting of the international yeast research community where the latest, and even unpublished results are exchanged, and new projects, alliances, and collaborations are founded. A do‐not‐miss‐event. We attempt to incorporate the present excitement in yeast research in the programme of yeast2019. We are confident that this conference will contain important news and information for all yeast researchers. Taken together, yeast2019 will provide an up‐ to‐date overview in yeast research and it will set the scene for years to come. -

Is C-26 Hydroxylation an Evolutionarily Conserved Steroid Inactivation Mechanism?
The FASEB Journal • Hypothesis Is C-26 hydroxylation an evolutionarily conserved steroid inactivation mechanism? Steve Meaney Division of Clinical Chemistry, Karolinska Institutet, Karolinska University Hospital, Huddinge, Sweden ABSTRACT Sterols are essential components of vir- steroid that can transduce an appropriate signal by tually all higher eukaryotic organisms, though the exact interacting with its cognate receptor, which may be a identity of the dominating sterol varies between spe- classical nuclear hormone receptor such as the estro- cies, from the C-27 of cholesterol in vertebrates to the gen receptor or a membrane receptor such as the C-28 and C-29 sterols of plants and invertebrates. In brassinosteroid receptor (6, 7). As a result of their addition to their role as structural components of cell potent biological activity, it is of paramount importance membranes these sterols are also converted into a for an organism to control the active levels of these variety of biologically active hormones. This conversion hormones, and sophisticated mechanisms have evolved generally involves modifications of the basic structure to deactivate and subsequently eliminate them (8). Due of the sterol by dealkylation, hydroxylation and/or to the presence of numerous hydroxyl and keto groups, isomerization. Recent studies have demonstrated that these hormones are suitable for such (phase II type) irreversible inactivation of both plant and insect hor- modifications as glucuronidation and sulfonation. This mones is achieved by a specific C-26 hydroxylation. The situation is exemplified by mammalian steroid hor- concept of sterol deactivation by 26-hydroxylation ap- mones such as estrogen and testosterone, which are pears to be an example of an evolutionarily conserved excreted as sulfate and/or glucuronide conjugates.
