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 ... -
Phenotypic response to a major hurricane in Anolis lizards in urban and forest habitats
(2021-04-20)Little is known about the synergistic impacts of urbanization and hurricanes on synanthropes. We compared morphological traits of the lizard Anolis cristatellus on Puerto Rico sampled before the 2017 category 5 Hurricane ... -
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 ... -
Effects of the cranial parasite Tylodelphys sp. on the behavior and physiology of puye Galaxias maculatus (Jenyns, 1842)
(2021)Diplostomatid digeneans are well-known manipulators of the behavior of their intermediate hosts. Unencysted metacercariae of Tylodelphys sp. inhabit the cranial cavity of the fish Galaxias maculatus; however, to date they ... -
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 ... -
Do non-native sea anemones (Cnidaria: Actiniaria) share a common invasion pattern? – A systematic review
(2021)A number of cnidarian species are known to have become marine invaders across a diversity of regions and habitats, including sea anemones of the order Actiniaria. Unfortunately, integrative approaches to identify and ... -
Development of global temperature and pH calibrations based on bacterial 3-hydroxy fatty acids in soils
(2021)Gram-negative bacteria produce specific membrane lipids, i.e. 3-hydroxy fatty acids with 10 to 18 C atoms. They have been recently proposed as temperature and pH proxies in terrestrial settings. Nevertheless, the existing ... -
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 ... -
COVID lessons from the global south – Face masks invading tourist beaches and recommendations for the outdoor seasons
(2021-09)In response to the COVID-19 pandemic in 2020, Personal Protective Equipment (PPE) has been extensively used, and discarded PPE has been observed in many different environments, including on tourist beaches. Here we examined ... -
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 ... -
Climatic regulation of vegetation phenology in protected areas along Western South America
(2021)Using 19 years of remotely sensed Enhanced Vegetation Index (EVI), we examined the effects of climatic variability on terrestrial vegetation of six protected areas along southwestern South America, from the semiarid edge ... -
Climate and land cover trends affecting freshwater inputs to a fjord in Northwestern Patagonia
(2021-07)Freshwater inputs strongly influence oceanographic conditions in coastal systems of northwestern Patagonia (41–45°S). Nevertheless, the influence of freshwater on these systems has weakened in recent decades due to a marked ... -
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 droughts in the southern Andes (40–45°S) from an ensemble experiment using CMIP5 and CMIP6 models
(2021)The decrease in freshwater input to the coastal system of the Southern Andes (40–45°S) during the last decades has altered the physicochemical characteristics of the coastal water column, causing significant environmental, ...
