There is limited information <br>on the diversity and ecology of this genus along the coasts of Mexico. The objectives of this study were to identify <br>by the use of integrative taxonomy (morphological and molecular) two isolates of Coolia (CMBAPAZ-1 and s/i 72) <br>from Bahía de la Paz, Gulf of California and to determine the effects of the extracts from the macroalga Dictyota dichotoma on their growth. Both isolates were cultured in GSe medium with and without macroalgal extracts: 1) GSe <br>medium, 2) GSe with the addition of the crude extract of D. dichotoma, 3) GSe with the addition of the carbohydrate <br>fraction of D. dichotoma, and 4) GSe with the addition of the non-precipitable fraction of D. dichotoma. Morphological and molecular analyses of the 28S region of rDNA (bootstrap values &gt; 95%) confirmed the identification <br>of the isolates as Coolia malayensis. There were no significant differences (p &lt; 0.05) in the cell abundances of two <br>strains in GSe medium compared with the other treatments. The maximum abundances found in strains CMBAPAZ-1 and s/i 72 at 28 days of culture were 40,271 ± 3,018 and 43,428 ± 4,560 cells mL-1, respectively. The growth <br>rate ranged from 0.129 to 0.139 div day-1 in both strains. The extract and fractions of D. dichotoma neither favored <br>nor inhibited the growth of C. malayensis; therefore, the possibility that the macroalga may favor the growth of this <br>dinoflagellate in its natural environment is not excluded</p> 2023-03-15T00:00:00+00:00 Copyright (c) 2022 Ana Emilia Ramos Santiago SYSTEMATIC LIST UPDATE OF THE CLASS GASTROPODA IN THE CENTRAL AND NORTHERN COAST OF SONORA, GULF OF CALIFORNIA 2023-03-16T15:17:20+00:00 Adrian Arvizu -Ramirez Hector Reyes -Bonilla Angelica Paulina Riesgo -Ruiz <p>Diversity studies and research have included members of the class Gastropoda from the Gulf of <br>California. Still, the majority have been researched in a rudimentary or secondary way, with literature not specific <br>to the region causing discrepancies in the nomenclature of the taxa. This could affect the information on some taxa. <br>It could also affect the malacological knowledge of the region. Therefore, an updated fauna inventory was built for <br>71 families of the class Gastropoda on the coast of Sonora based on latitudinally-referenced information of 3261 <br>records of species names from the region (27° N – 31° N), obtained from official electronic databases and physical <br>revision of malacological material from a museum. Depuration and taxonomic updates were performed when the <br>obtained information was compared with the World Register of Marine Species platform. As a result, 26.64% of <br>the species’ names showed status updates, resulting in 713 valid names of gastropods. The latitudinal distribution <br>highlighted 27° N and 31° N with the greatest data and species diversity. The easy access to port cities (in the <br>previously mentioned latitudes) makes them suitable points for scientific research since they have demonstrated a <br>strong bias compared to intermediate latitudes.</p> 2023-03-15T00:00:00+00:00 Copyright (c) 2023 CICIMAR Oceánides PUBLICATION ANOMALIES AND “PAYWALL” WOES IN ACADEMIA 2022-10-27T16:13:33+00:00 Prasanta Panda <p>. It is a boon to enhance the base in any encyclopaedias by adding new found knowledge for newer <br>superstructures that can lead to civilizational growth. However, the newly found knowledge should be profound <br>enough to be considered as the base. Otherwise, the superstructure of knowledge will not be of any use to meet the <br>requirement of civilizational growth. This essay is investigative to see through the anomalies the worldwide publi- cation web has at the present moment of history and the far-reaching negative impact it may ensure if the presentday academia is not responding to the suggestions made by the researchers in this context</p> 2023-03-15T00:00:00+00:00 Copyright (c) 2022 Prasanta Panda
