Article
Full-text available
Natural resource management requires extensive knowledge of the biology of the organisms and their responses to ecological and anthropogenic processes. While species are commonly used as management units, the presence of cryptic species morphologically indistinguishable, but with different biological characteristics may hinder the design of appropr...

Full-text available
In numerous taxa, studies have reported the co-occurrence of several copies for a single mitochondrial marker (heteroplasmy), leading to incorrect phylogenetic inferences if not detected. While this phenomenon has been widely investigated in terrestrial taxa, it remains largely unexplored in marine algae. Here we report the detection of heteroplasm...

Background The Chilean shoreline, a nearly strait line of coast expanding across 35 latitudinal degrees, represents an interesting region to assess historical processes using phylogeographic analyses. Stretching along the temperate section of the East Pacific margin, the region is characterized by intense geologic activity and has experienced drast...
Article
Full-text available
A major determinant of the geographic distribution of a species is expected to be its physiological response to changing abiotic variables over its range. The range of a species often corresponds to the geographic extent of temperature regimes the organism can physiologically tolerate. Many species have very distinct life history stages that may ex...

Chondracanthus chamissoi is part of the diet of coastal people from Peru and is exported dehydrated to Asian countries for direct consumption. Although it is considered endemic to Peru and Chile, its range has extended to distant regions, such as Korea, Japan, and France. Using morphological and molecular approaches, we examined specimens from Peru...
Article
Full-text available
The red seaweed Chondracanthus chamissoi shows high morphological variability. Initially, three species were identified based on the width of the main axis of their blades. Later, all of them were included in a single species with two morphological groups. Recently, quantitative studies demonstrated the existence of two forms in C. chamissoi: f. le...

Full-text available
Harvest pressure on brown macroalgae of the Lessonia genus has increased in recent years in Peru and Chile, due to the high demand from the global hydrocolloid industry. After a taxonomic review, in 2012, the intertidal species Lessonia nigrescens was segregated into two species, being L. berteroana distributed in southern Peru and northern Chile (...
Article
Phyllophorella was recently described from two localities on the central coast of Peru (12°S), based on the endemic species Phyllophora (Ph.) peruviana. The genus currently accommodates three species, Phyllophorella (P.) peruviana, P. humboldtiana and P. limaensis. Recent field surveys for Phyllophorella on the central coast of Peru led to the disc...

Siete especies de Rhodymenia han sido registradas para la costa de Perú, donde seis de ellas crecen en la costa central: R. corallina, R. howeana, R. multidigitata, R. flabellifolia, R. skottsbergii y R. californica. La más conflictiva taxonómicamente es R. corallina, de la cual se han segregado R. howeana y R. multidigitata, solo en base a caracte...
Article
Full-text available
The systematic of bladed Bangiales is suffering significant changes at a global level, due to the inclusion of new genera, such as Pyropia, and the incorporation of molecular evidence. In Chile, the application of molecular tools has shown a high diversity of species in genera Porphyra and Pyropia, with species delimitations that do not correspond...

Aim: This study examines how rafting on floating bull kelps can shape the biogeographic patterns of raft-associated species, and analyses the spatio-temporal variability of taxonomic richness and co-occurrences of epibionts on beach-cast rafts of Durvillaea antarctica along a latitudinal gradient. Location: Southeast Pacific, along ~1,700 km of coa...
Article
Full-text available
Rafting on floating seaweeds facilitates dispersal of associated organisms, but there is little information on how rafting affects the genetic structure of epiphytic seaweeds. Previous studies indicate a high presence of seaweeds from the genus Gelidium attached to floating bull kelp Durvillaea antarctica (Chamisso) Hariot. Herein, we analyzed the...

Full-text available
Non-native ascidians are important members of the fouling community associated with artificial substrata and man-made structures. Being efficient fouling species, they are easily spread by human-mediated transports (e.g., with aquaculture trade and maritime transports). This is exemplified by the ascidian Asterocarpa humilis which displays a wide d...
Data
Phylogenetic tree of cytochrome c oxidase subunit I (COI) haplotypes for the family Styelidae, constructed by the neighbor-joining method Sequences obtained in the present study are identified in the tree as Ah COI ShipCH (1 to 3) and FarmCH, and Accession Numbers refer to sequences from GenBank. Two haplotypes were found: one (Ah COI ShipCH3) is i...
Data
Survey sites (harbors, aquaculture facilities and natural habitats) Gray circles correspond to locations where A. humilis was encountered (1 = Coliumo, 2 = Lirquén port, 3 = Talcahuano port, 7 = Llico) and black circles indicate visited sites where A. humilis is absent (4 = San Vicente port, 5 = Chome, 6 = Coronel port).

Article
Full-text available
Dispersal on floating seaweeds depends on availability, viability and trajectories of the rafts. In the southern hemisphere, the bull kelp Durvillaea antarctica is one of the most common floating seaweeds, but phylogeographic studies had shown low connectivity between populations from continental Chile, which could be due to limitations in local su...
Article
The intertidal coast of Chile has two cryptic kelp species, Lessonia spicata and L. berteroana, which share closely situated, but not overlapping, high-energy habitats. Their populations recover slowly after major disturbances and massive mortalities, suggesting that dispersal from remnant populations is strongly limited. This low dispersal is also...

Many seaweed species (primary rafters) float at the sea surface and travel with marine currents after detachment from benthic habitats. Various studies have confirmed that dispersal via floating sporophytes and/or gametophytes influences the phylogeography and genetic population structure of these buoyant seaweeds. In addition, non-buoyant seaweeds (se...

The coast along the temperate South East Pacific (SEP) presents a simple linear topography with a north-south orientation spanning more than 4600 km. However, environmental heterogeneity associated with two major biogeographic boundaries has been described along the SEP (30–33°S and 42°S). Recent phylogeographic studies of seaweeds revealed the exi...
Article
Species separation within the Lessonia nigrescens complex (Phaeophyceae, Laminariales) is mirrored by ecophysiological traits Abstract: Lessonia nigrescens used to be an abundant kelp species along the Chilean coast, but recent molecular studies revealed the existence of a L. nigrescens species complex, which includes the two cryptic species Lesson...

En el océano se ha observado gran cantidad de algas flotando a la deriva (1). En Chile, se reportan poblaciones bentónicas del alga parda Durvillaea antarctica desde el sur de Coquimbo hasta el Estrecho de Magallanes. Es frecuente encontrar individuos flotando a la deriva y varados en esta área, e incluso más al norte; esto sugiere que esta especie...

Full-text available
Tolerance to air exposure should be an important feature in determining the geographic distribution of seaweeds. Two sibling kelp species with contrasting latitudinal distributions were selected to test the relationship between their distribution and air exposure tolerance: Lessonia berteroana distributed between 18° and 30°S and Lessonia spicata,...

Article
During secondary contact between phylogenetically closely related species (sibling species) having diverged in allopatry, the maintenance of species integrity depends on intrinsic and extrinsic reproductive barriers. In kelps (Phaeophyceae), the observations of hybrids in laboratory conditions suggest that reproductive isolation is incomplete. Howe...
Article
Little is known about variation of sex ratio, the proportion of males to females, in natural populations of seaweed, though it is a major determinant of the mating system. The observation of sexual chromosomes in kelps suggested that sex is partly genetically determined. However, it is probably not purely genetic since the sex ratio can be modified...

Kelp forests are threatened by human activities that result in habitat loss or deplete natural stocks, but little is known about genetic diversity, importance of gene flow and effect of population fragmentation on genetic structure. We reviewed the literature to characterize the patterns of connectivity and scales of population structure in kelps....
Article
Phylogeographic studies are lacking in the Southern Hemisphere, and in particular in the south-eastern Pacific. To infer the possible scenario for the debated biogeographic transition zone located at 30-33 degrees S along the Chilean coast, we investigated whether there is a concordance between the phylogeographic pattern and the biogeographic tran...
Article
A total of nine microsatellite loci were isolated and characterized in the Chilean kelp Lessonia nigrescens Bory. Using two different enriched libraries, we observed 1-14 alleles per locus in two samples of 21 kelp individuals each. The observed heterozygosities ranged from 0.05 to 0.80 and all loci are in Hardy-Weinberg equilibrium for one or both...
