La mas conflictiva taxonomicamente es R. corallina , de la cual se han segregado R. howeana y R. multidigitata , solo en base a caracteres morfologicos externos (forma del estipe y habito de la fronda). Recolecciones recientes e intensivas de este complejo de especies en la costa central del Peru (9°S hasta 15°S) han permitido reunir varios morfotipos, evidenciando la alta variabilidad morfologica presente, que dificulta el poder diferenciar cada uno de los taxones involucrados. El objetivo del presente trabajo fue esclarecer la taxonomia de este complejo mediante la combinacion de datos morfologicos, tanto vegetativos como reproductivos, y de secuencias geneticas utilizando los marcadores rbc L y COI-5P. Especimenes de Callao, localidad tipo de R. howeana y R. multidigitata , fueron analizados molecularmente junto con material de la costa central (Casma hasta Marcona, 9-15°S) y norte de Peru (Piura, 6°S), asi como del norte chico de Chile (Coquimbo, 30°S), resolviendo dos grupos de Rhodymenia : un primer grupo filogenetico asociado a R. corallina de Chile (Coquimbo, 30°S), distribuido a lo largo de toda la costa central peruana (Casma hasta Marcona, 9-15°S) y un segundo grupo restringido a la costa norte de Peru (Piura a Casma, 6-9°S).

To date, 131 species have been described in Microcotyle ; however, more than half have been transferred to other genera, and several others have poor descriptions. Therefore, less than half of all Microcotyle species may be considered valid. In Chile, two species have been recognized, and unidentified Microcotyle have been found on several littoral fish , but there has been no effort to properly identify them. In this study, two new species of Microcotyle are taxonomically described from intertidal fish of the central (33°S) and south-central (36°S) regions of Chile. In this study, Microcotyle sprostonae n. sp. (collected mainly from Scartichthys viridis in central Chile) and M. chilensis n. sp. (collected mainly from Calliclinus geniguttatus in south-central Chile) were identified based on morphological and molecular analyses (ITS2 and 18S genes). Both species of Microcotyle principally differed from one another and from other valid species in the number of testes and clamps. The two new species also differed from one another by one base pair in the ITS2 and 18S genes and differed from other species of Microcotyle by several base pairs of both genes. Intertidal fish are mostly endemic to the Pacific coast of South America, and they have a limited geographical distribution that does not overlap with the type hosts of other Microcotyle species. Therefore, the two new species described here are distinguished from other congeneric species by morphological, genetic, and biological characteristics.","PeriodicalId":54475,"journal":{"name":"Revista De Biologia Marina Y Oceanografia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2020-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49047980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to provide new information concerning the spatial and bathymetric occurrence of B. australis in the Southern Pacific Ocean. To do this, all data and information available in scientific literature regarding Chile and the South Pacific Ocean were collected, including fishery dependent and independent as well as bycatch data. B. australis could be present in a wider latitudinal range from the 27°S to 57°S, including fjords, open ocean, and along a band in the Pacific Ocean, from New Zealand up to the Chilean coast. Thus, B australis shows a wider distribution compared to previous studies especially towards the Southern Chile. Bathymetrically the species occurs with a higher frequency in depths between 100 and 250 m, however a low occurrence was recorded over 500 m depth. A potential association of B. australis with the West Wind Drift, which could influence the distribution of the species in the Pacific Ocean and off the Chilean coast, is hypothesized. Further work includes taxonomic studies to confirm the presence of the same species in the distributional area proposed here","PeriodicalId":54475,"journal":{"name":"Revista De Biologia Marina Y Oceanografia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2019-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43087818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of the spatial and temporal distribution of these vertebrates has been revolutionized with technological advances such as satellite telemetry, which in the last two decades has substantially increased its implementation. This technology attends the need of knowing and locating their critical habitats (such as inter-nesting, migrating, feeding and mating) as well as know their migratory movements for the understanding of their biology and protection through the deployment of satellite transmitters on sea turtle individuals. Because the cost of a satellite transmitter is high, its effective deployment on a sea turtle in a quickly, safely, and firmly way is of vital interest to the researcher to ensure that the transmitter persists for an extended time maximizing the information contribution and benefit the research. In this context, the objective of this contribution is to describe and document experiences applying standardized and verified methodological steps for deploying satellite transmitters on hard shell marine turtles. This contribution represents a documented and step-by-step viable description on the path to have clear and versatile basis as reference for the satellite transmitter deployments.","PeriodicalId":54475,"journal":{"name":"Revista De Biologia Marina Y Oceanografia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2018-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.22370/RBMO.2018.53.2.1289","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45293459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
