Of the 183 species recognized as valid only 16 are distributed in the eastern Pacific. Two endemic species and only members of the family are found in the FFS Malpelo Island: Axoclinus rubinoffi y Lepidonectes bimaculatus. In this work, additional data are provided on the adults and larvae of the triplefins of the sanctuary. The mean abundances of the larvae were 1,88 individuals/m2\u0000 for A. rubinoffi and 0.25 individuals/m2 for L. bimaculatus at the night stations where they were collected, 0.8 and 1.61 km to the west of the island and very close specifically on El Arrecife and La Nevera. The adults were collected around the island between 0-30 m depth and the abundance was 0.22 individuals/m2 for L. bimaculatus and 0.19 individuals/m2 for A. rubinoffi. The natural variability of the morphological traits of both\u0000species is extended and differences between the population densities with previous studies are found. To really understand the population dynamics of these species, it is necessary to evaluate long time series and include other methods such as genetic information.","PeriodicalId":35743,"journal":{"name":"Boletin de Investigaciones Marinas y Costeras","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69643501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This species has solitary habits, haul out on pack ice for long period, and individuals tend to congregate in the same areas during the mating season. The leopard seal shows site fidelity to reproductive sites, which may imply restricted gene flow between groups. In order to conduct the first assessment of genetic diversity of leopard seals in waters around Danco Coast in the Antarctic Peninsula, we amplified mitochondrial DNA Control Region (mtDNA-CR, 423 bp) from DNA extracted from 13 blood samples collected in Primavera Base (62o15'S, 58o39'W) during 2011-2012 austral summer. Our results showed high haplotype diversity (h = 0.989), represented in one unique haplotype for each sample, and only one haplotype shared between two samples. Network analyses confirmed high diversity with some divergent haplotypes. Our genetic findings suggest that individuals sampled belong to one population. Due to ice dynamic as a consequence of climate change, many individuals are shifting their diet habits, showing dietary specializations that may have the potential to promote genetic differentiation in the long-term. However, given the lack of leopard seals genetic studies, this hypothesis cannot be tested. Research studies using mitochondrial and nuclear markers are needed to assess the genetic status of leopard seals and their population structure in relation with other populations, particularly to determine restrictions to gene flow likely related to dietary specialization among leopard seals populations.","PeriodicalId":35743,"journal":{"name":"Boletin de Investigaciones Marinas y Costeras","volume":" ","pages":"227-238"},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49291639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we map the spatial distribution of diapycnal diffusivities and the water column characteristics across the three main bays in the Gerlache Strait on the western side of the Antarctic Peninsula. The measurements were recorded during the Fifth Colombian Antarctic Expedition, 2018-2019, using a Vertical Microstructure Profiler in free fall for the first 400 m depth, to record fluctuations of vertical shear at dissipation\u0000scales (10-3 – 103m). Diapycnal diffusivities are higher by 1-2 orders of magnitude in the Gerlache mainstream compared with the interior bays, with values from O (log10kρ = -3 m2 s -1) to O (log10kρ = -5 m2s -1) respectively over the upper 400 m. The highest mixing values were recorded in the southern section of Gerlache Strait (Flandes Bay) compared to the northern one (Charlotte Bay), indicating better wellmixed water in the south. Observed Hot Spots of higher turbulence levels may be associated with the interaction of the entrance of the Upper Circumpolar Depth Water, the Antarctic Surface Water, and the Weddell Sea Deep Waters with resident waters and topography.","PeriodicalId":35743,"journal":{"name":"Boletin de Investigaciones Marinas y Costeras","volume":"50 1","pages":"41-58"},"PeriodicalIF":0.0,"publicationDate":"2021-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48461394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
