Poly(4-vinylbenzyl)trimethylammonium chloride) resin with removal properties for vanadium(v) and molybdenum(vi). A thermodynamic and kinetic study
(2021-01)Ion exchange resin poly(4-vinylbenzyl) trimethylammonium chloride(P(ClVBTA)) was synthesized and its removal properties toward vanadium(V) and molybdenum(VI) were evaluated and compared with those of the Amberlite IRA-402 ... -
Effects of feeding with different live preys on the lipid composition, growth and survival of Octopus vulgaris paralarvae
(2021-01)To move forward in the farming of Octopus vulgaris paralarvae, it is necessary to search for a live prey easy to obtain and maintain in the laboratory that meets the nutritional requirements of the octopus paralarvae and ... -
Diet, trophic interactions and possible ecological role of commercial sharks and batoids in northern Peruvian waters
(2021-03)The Peruvian sea represents one of the most productive ocean ecosystems and possesses one of the largest elasmobranch fisheries in the Pacific Ocean. Ecosystem-based management of these fisheries will require information ... -
Fatty acid biomarkers in three species inhabiting a high latitude Patagonian fjord (Yendegaia Fjord, Chile)
(2021)The study of fatty acid biomarkers in trophic structures at sub-polar latitudes is fundamental in describing energy fluxes across ecosystems characterized by complex inter-specific interactions. Due to the presence of ... -
Exploring overlooked components of remote South-east Pacific oceanic islands: Larval and macrobenthic assemblages in reef habitats with distinct underwater soundscapes
(2021-02)Identifying the diverse assemblage of species inhabiting rocky and coral reef habitats in isolated oceanic environments, and the important sound cues emitted from the reef, are crucial components to understand how species ... -
Endemic species dominate reef fish interaction networks on two isolated oceanic islands
(2021)Ecological interactions are found across ecosystems, facilitating comparison among systems with distinct species composition. The balance of positive and agonistic interactions among species may be sensitive to variation ... -
Ecomorphological analyses reveal impact of land-based stressors on stock structure of two commercially important fish species (Lutjanus synagris and Haemulon plumierii) in the Caribbean
(2021-02)Many Caribbean nations lack information on the ecology and biology of marine species, which are essential for food security and livelihoods in the region. This study aimed to advance the knowledge of two commercially ... -
Development of silicone-coated hydrophobic deep eutectic solvent-based membranes for pervaporation of biobutanol
(2021-11)Hydrophobic Deep Eutectic Solvents (HDES) are considered a relatively novel class of solvents, which show perfect features to incorporate them in pervaporation membranes. Composite HDES membranes offer a separation media, ... -
Daily accumulation rates of marine litter on the shores of Rapa Nui (Easter Island) in the South Pacific Ocean
(2021-08)Large amounts of floating litter accumulate in the subtropical gyres, and the shorelines of oceanic islands in the vicinity of these accumulation zones receive large amounts of litter. The dynamics of marine litter arrival ... -
Computational study of the binding mode, action mechanism and potency of pregabalin through molecular docking and quantum mechanical descriptors
(2021)In the present study, we performed a computational study to gain insights on the binding mode and high affinity of pregabalin, its inactive isomer (R-pregabalin) and gabapentin when modulating voltage-gated calcium channels. ... -
Comparison of lipids and fatty acids among tissues of two semiterrestrial crabs reveals ecophysiological adaptations in changing coastal environments
(2021-09)Decapods have successfully colonized changing coastal habitats throughout the world by adapting their behavior, physiology, and biochemistry. Biochemical reserves, such as lipids and fatty acids (FAs), play fundamental ... -
Inbreeding vs outbreeding depression in a marine species with low dispersal potential
(2021)Inbreeding depression strongly affects the biological fitness of organisms throughout their life cycle. These negative effects are more pronounced in species with low dispersal potentials, where mating among relatives ... -
Hydrological connectivity drives longitudinal movement of endangered endemic Chilean darter Percilia irwini (Eigenmann, 1927)
(2021)Movement is a fundamental aspect of fish ecology, and it therefore represents an important trait to monitor for the management and conservation of fish populations. This is especially true for small benthic fish, as they ... -
Carbonization of microalgae for bio-coal production as a solid biofuel similar to bituminous coal
(2021-10-15)The carbonization of Nannochloropsis gaditana microalgae biomass was found to produce bio-coal that is similar to bituminous coal used in thermal power plants. Currently, microalgae that capture CO2 while they are in the ... -
Bioenergetic traits of three keystone marine species in the food web of a pristine Patagonian fjord
(2021-01)The Patagonian fjords are high-latitude aquatic ecosystems, highly sensitive to climate change and play a key role in the exchange of organic matter and carbon flows between terrestrial and marine environments. The ... -
Age dependent physiological tolerances explain population dynamics and distribution in the intertidal zone: A study with porcelain crabs
(2021-07)Population dynamics and their response to environmental stressors have been widely studied in intertidal organisms. However, how these dynamics and responses change with animal age have been largely ignored to date. ... -
A decade later, reviewing floating marine debris in Northern Chilean Patagonia
(2021)Floating marine debris (FMD) were abundantly reported in the Northern Chilean Patagonia in 2009 where sea-based activities (mussel and salmon aquaculture) are responsible for most of them. Identifying the sources of FMD ... -
A country's response to tackling plastic pollution in aquatic ecosystems: The Chilean way
(2021-02)Marine plastic pollution is worse than expected, and we are starting to realize its full extent and severity. Solving the plastic pollution problem is not easy, as it requires the action and commitment of all sectors of ... -
Fatty acid composition in the endemic Humboldt Current krill, Euphausia mucronata (Crustacea, Euphausiacea) in relation to the phytoplankton community and oceanographic variability off Dichato coast in central Chile
(2020-10)Fatty acids (FA) have been used as diet biomarkers. They have proven to be a valuable method of defining food web relationships, trophic positioning, and the dietary behaviors of marine species. The endemic krill species ...
