  1. 1. INVESTIGATING THE TOXIC AND ACIDIFYING EFFECT OF SCRUBBER EFFLUENT ON STRONGYLOCENTROTUS DROEBACHIENSIS LARVAE

    University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Author : Ida Vartia; [2022-09-28]
    Keywords : ;

    Abstract : To meet the new environmental requirements of reduced sulfur emissions from ships, many shipowners have installed an open-loop scrubber to clean the exhaust. In this scrubbing process, seawater is pumped from the ocean and combined with the emission gas, creating an acidic and toxic effluent that is directly discharged into the ocean, potentially damaging the marine environment.

  3. 2. Fluctuating pH simulating natural variability modulates larval growth for Strongylocentrotus droebachiensis

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Bryn Anderson; [2022-08-05]
    Keywords : ocean acidification; global change; sea urchin; duration; intensity; biological response;

    Abstract : Ocean acidification (OA) is the downward trend of ocean pH mainly resulting from the absorption of carbon dioxide (CO2) emissions from anthropogenic sources. pH of the open ocean is expected to drop to 7.7 by the end of the century. READ MORE

  4. 3. Characterization of MITF gene in crayfish and their possible role in innate immunity

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Yaru Wen; [2020]
    Keywords : Microphthalmia-associated transcription factor; basic Helix-Loop-Helix Leucine Zipper; crayfish; Aphanomyces astaci; immunity;

    Abstract : Microphthalmia-associated transcription factor (MITF) is a tissue-specific transcription factor (TF), with a basic helix-loop-helix leucine zipper (bHLH-LZ) domain, which binds to the canonical E-box sequence (5’-CANNTG-3’) in the promoter region of target genes. In this study, the MITF-like protein was identified in the marbled crayfish (Procambarus virginalis). READ MORE

  5. 4. Paleoecology and sedimentology of the Upper Cretaceous (Campanian), marine strata at Åsen, Kristianstad Basin, Southern Sweden, Scania

    University essay from Lunds universitet/Geologiska institutionen

    Author : Faisal Javed Iqbal; [2013]
    Keywords : Campanian; Belemnellocamax mammilatus Zone; Belemnellocamax balsvikensis Zone; Brachiopods; Bivalves; Belemnites; Bryozoans; Barnacle; Sea urchin; corals; coprolites; shark teeth; vertebrate fossils; XRF; Sr Ca; Steinkern; Earth and Environmental Sciences;

    Abstract : The Campanian marine strata from Åsen, north east part of the Kristianstad Basin (southern Sweden) contain a most diverse vertebrate and invertebrate marine fossil assemblages. A diverse fossil fauna was collected from Campanian deposits from a ca. 4.15m thick section during June-August 2010-2012. READ MORE

  6. 5. Population genetic structure and connectivity of the abundant sea urchin, Diadema setosum around Unguja island (Zanzibar).

    University essay from Institutionen för livsvetenskaper

    Author : Josefine Larsson; [2009]
    Keywords : Diadema setosum; population structure; Zanzibar; AFLP;

    Abstract : The distribution and abundance of many coral reef organisms are affected by their predator’s distribution and abundance. Loss of predators may cause a shift in species compositions that will cascade down to other ecological processes on the reef. READ MORE
