El contenido de proteinas fue mas alto en C. sertularioides, S. filamentosa y G. vermiculophylla (10–12%), seguido de R. riparium, P. durvillaei y U. expansa (8%, 6% y 4%, respectivamente). El contenido de lipidos se encontro en el intervalo de 0.3–1.5%, con el valor mas alto encontrado en R. riparium. El contenido mas alto del extracto libre de nitrogeno (i.e., carbohidratos) (69%) y el valor mas bajo de cenizas (25%) se encontro en P. durvillaei. El contenido de acidos grasos poliinsaturados (AGPI) se encontro en el intervalo del 5% al 45%, con los valores mas altos en R. riparium (45%), C. sertularioides (39%) y P. durvillaei (23%). Las algas rojas mostraron el mayor valor de colesterol+dehidrocolesterol (>90%), mientras que las algas verdes mostraron el mayor contenido de β-sitosterol (71–77%), excepto U. expansa, para la cual el principal esterol fue el fucoesterol+isofucosterol (79%). El contenido de pigmentos fue diferente entre las algas, aunque coincidio con reportes previos. Los componentes bioquimicos usados como biomarcadores se analizaron por componentes principales para discriminar entre las variables analizadas y agrupar las especies de algas en funcion de la variabilidad de su composicion bioquimica. Los resultados mostraron una composicion similar en cada grupo de algas, pero particularmente diferente en U. expansa y P. durvillaei. Los compuestos bioquimicos que contribuyeron a la variabilidad total fueron β-sitosterol, 20:4n-6, 20:5n-3, clorofila a y b, β-caroteno y, en menor grado, fucosterol+isofucosterol y 22:6n-3. Los resultados indican que las especies de algas analizadas podrian ser utilizadas como alimento para animales, pero tambien para consumo humano.

El objetivo de este estudio fue evaluar la identidad real de las poblaciones mediterraneas de Tigriopus y dilucidar su taxonomia y patron de diversidad genetica. Con este fin, se secuencio un fragmento del gen de ADN mitocondrial (citocromo c oxidasa subunidad I, COI) como marcador de referencia. Los resultados sugieren la presencia de una sola especie caracterizada por una estructuracion genetica con una notable base geografica en toda el area de estudio. El patron de diversidad observado aqui se atribuye tentativamente a una fuerte monopolizacion de las charcas de las costas rocosas por parte de los primeros inmigrantes que las alcanzan. Sin embargo, tal monopolizacion se interrumpe periodicamente por los eventos de extincion local, los cuales son frecuentes en los habitats de charcas de rocas que son intrinsecamente inestables. Aqui proponemos para este patron el nombre de “monopolizacion periodica” (“clockwork monopolization”). EnglishThe copepod genus Tigriopus Norman, 1869 is distributed worldwide in coastal rock pools and it is currently considered to include 14 valid species. Tigriopus fulvus (Fischer 1860), with its subspecies Tigriopus fulvus adriaticus Van Douwe 1913 and Tigriopus fulvus algiricus Monard 1935, and Tigriopus minutus Bozic 1960 are currently reported to occur in the Mediterranean area, but the actual diversity of the genus is currently unknown. We aimed to assess the actual identity of Mediterranean Tigriopus populations and to elucidate their taxonomy and pattern of genetic diversity. In order to reach these goals, a fragment of a mitochondrial DNA gene (cytochrome c oxidase subunit I, COI) was sequenced to be used as a reference marker. Our data suggest the presence of a single species characterized by a noteworthy geographically based genetic structure in the whole study area. The observed diversity pattern is tentatively ascribed here to a strong monopolization of the rock pools by the first immigrants that reached them. However, such a monopolization is periodically disrupted by local extinction events, which are frequent in the intrinsically unstable rock pool habitats. We propose the name “clockwork monopolization” for this pattern.","PeriodicalId":50702,"journal":{"name":"Ciencias Marinas","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2019-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48704201","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}

Para ello, se realizaron busquedas directas por medio de buceo libre o autonomo en 13 playas cubriendo los estratos del intermareal, submareal somero y submareal profundo.

One of these toxins gave way to a new medication and two other are under development for clinical and cosmetic purposes. Nevertheless, there is little basic knowledge about this group of species, particularly in Mexico. This study aimed to determine the relative abundance, spatial distribution, bathymetric distribution, and habitat preference of the snail Conus princeps along the southern coast of Jalisco (Mexico). To achieve this goal, we conducted direct samplings by snorkeling or scuba diving at 13 beaches, covering the intertidal, shallow subtidal, and deep subtidal zones. Relative density was between 0.021 and 0.418 snails per 100 m2, with an average value of 0.152 snails per 100 m2. The population showed an aggregated spatial distribution pattern according to the nearest neighbor index. Snails had shells that measured between 23.1 mm and 52.2 mm long, with an average shell size of 39.7 mm. Conus princeps was mainly distributed in the intertidal and shallow subtidal zones.

La proporcion sexual (H:M) total (1.00:1.03) no difirio de la relacion esperada de 1:1. Las hembras fueron, en promedio, mas grandes que los machos.

Las hembras fueron clasificadas como desovadoras parciales con desarrollo asincronico de los ovocitos. Los machos presentaron testiculos con desarrollo espermatogonial sin restriccion. Debido a que se observaron individuos maduros y ovocitos hidratados durante ciertos meses, la especie puede estar desovando dentro de la laguna; sin embargo, seria necesario demostrar la presencia de huevos y larvas para asegurar esto.

Observed total sex ratio (F1.00:M1.03) was not significantly different from the expected 1:1 ratio. Females were, on average, larger than males. The observed monthly gonadosomatic index, percentage of mature gonads, mean oocyte diameter, and ovarian-wall thickness suggest that the species reproduces year-round, with an important reproductive season lasting from April to August. Females were classified as partial spawners with asynchronous oocyte development, and males showed unrestricted spermatogonial testes. The presence of spawned individuals and hydrated oocytes in certain months indicates that the species could be spawning in the lagoon; however, the occurrence of eggs and larvae needs to be demonstrated to ascertain this statement.

This change in editorship concurs with the 45th anniversary of the establishment of Ciencias Marinas and marks the beginning of a new phase in the growth and development of our scholarly journal. The editorial team has thus far completed many projects, such as updating our publishing platform, all aimed to improve journal presentation, visibility, and accessibility. It has now taken the first steps in transitioning from an electronic publishing format to a completely digital format, and it will continue to work hard to guarantee that Ciencias Marinas continues evolving. \u0000Over these past 45 years Ciencias Marinas has been a conduit for the professional and inclusive delivery of sound scientific information on the four disciplines of marine science (biology, physics, geology, and chemistry). At the moment we are focusing on strengthening our international support system to reach higher publishing standards. To achieve this goal, we are expanding, refining, and updating our editorial board, which now includes even more international experts with outstanding academic careers. We will continue to expand our editorial board by extending additional invitations to other experts who wish to collaborate in this project that is Ciencias Marinas, and we hope to soon welcome new member to our board. \u0000I would now like to take the opportunity to thank previous editors-in-chief for their contributions, which have elevated our journal to its current position. Their contributions give me a great advantage to further improve the quality of the journal products. I am also thankful to the members of the editorial board, who have provided much support by efficiently and professionally managing the editorial processes of our submissions. As a result of this work, our list of reviewers has significantly increased in number and quality, and this will reflect on the quality of the papers we publish.
