To determine whether or not this afects the biology of the water column, we explored the infuence of surface water properties on phytoplankton productivity in four embayments of the South Shetland Islands (SSI) during late summer of 2013. We analyzed hydrographic, climatic, and primary productivity satellite data (wind velocity, sea-ice cover, and chlorophyll-a), in situ CTD measurements of physical and chemical characteristics, new estimates of net primary production (NPP), and surface water samples for chlorophylla, nutrients, biogenic silica, and plankton composition...Leer artículo |

Here, we developed a simple microsatellite multiple assay to evaluate the mating strategy and male reproductive success of the marine gastropod Concholepas concholepas (Bruguie `re, 1789),an important fishery resource and a key predator species of Chilean rocky shore communities. Concholepas concholepas is a dioecious species with internal fertilization, encapsulation, and long larval phase. Ver PDF |

We examined spatial and seasonal changes in the hydrography, sediment conditions and soft-bottom macrobenthic, meiobenthic, and total microbial biomass in a glacial Patagonian fjord (Martinez Channel, Chile). The transport of a high load of glacial mineral and particulate OM to the fjord in the austral summer coincided with low total live benthic biomass. Ver PDF |
| Bentos | 2017 | Rojas-Hernández N., Véliz D., Riveros M., Fuentes J., Pardo L. | Highly Connected Populations and Temporal Stability in Allelic Frequencies of a Harvested Crab from the Southern Pacific Coast | Plos One | For marine invertebrates with a benthic adult form and a planktonic larva phase, the connectivity among populations is mainly based on larval dispersal. While an extended larval phase will promote gene flow, other factors such as an intensive fishery and geographical barriers could lead to changes in genetic variability. In this study, the population genetic structure of the commercial crab Metacarcinus edwardsii was analyzed along 700 km of the Chilean coast. Ver PDF |
| Bentos | 2017 | Cruces E., Flores-Molina M., Díaz M., Huovinen P., Gómez I. | Phenolics as photoprotective mechanism against combined action of UVradiation and temperature in the red alga Gracilaria chilensis? | Appl Phycol | The rhodophyte Gracilaria chilensis is a structuring species of the estuarine and fjord systems in southern Chile and is commercially exploited from natural and farmed populations. Due to its capacity to tolerate extreme variations in environmental conditions, this species is an excellent model organism to examine stress tolerance mechanisms. The present study examined the combined effect of temperature and UV radiation on the reproductive phases of G. chilensis (carposporophyte, tetrasporophyte, and vegetative) at the lower and upper intertidals of the Valdivia River estuary. The concentration of phenolic compounds and their antioxidant capacity as well as the inhibition of primary photochemical reactions, measured as the fluorescence of photosystem II, was determined.

The meiofauna play an important role in the ecology of marine ecosystems and the functions they provide. Using microcosms, meiofaunal assemblages were exposed to two temperatures (15 and 19 °C) and two pHs (pCO2 of 400 and 1000 ppm), both individually and in combination, for a period of 90 days.

| Bentos | 2017 | López D., Camus P., Valdivia N., Estay S. | High temporal variability in the occurrence of consumer–resource interactions in ecological networks | Oikos | Ecological networks have been used to represent interactions between species as fixed linkages despite that populations naturally oscillate over time and space. As such, the influence of the persistence of linkages between species in communities has been overlooked. Unfortunately, empirical analysis of the temporal variation of trophic networks is constrained by the lack of data with high spatial, temporal and taxonomic resolution. Ver PDF |

Paradoxically, mapping approaches meant to inform policy decisions focus on the magnitude and spatial distribution of the biophysical supply of ES, largely ignoring the social mechanisms by which these services influence human wellbeing.Ver PDF |
