Latitudinal patterns in the diet of Andean condor (Vultur gryphus) in Chile: Contrasting environments influencing feeding behavior
(Chile. Universidad Mayor, 2020)Human-dominated environments alter the availability and quality of resources for many species, especially for scavengers that have large home ranges and plastic foraging behaviors that enable them to exploit novel resources. ... -
Legacy and novel flame retardants from indoor dust in Antarctica: Sources and human exposure
(Chile. Universidad Mayor, 2020)The air humidity in Antarctica is very low and this peculiar weather parameter make the use of flame retardants in research facilities highly needed for safety reasons, as fires are a major risk. Legacy and novel flame ... -
Macroecological factors shape local-scale spatial patterns in agriculturalist settlements
(The Royal Society, 2017)Macro-scale patterns of human systems ranging from population distribution to linguistic diversity have attracted recent attention, giving rise to the suggestion that macroecological rules shape the assembly of human ... -
Maintaining close canopy cover prevents the invasion of Pinus radiata: Basic ecology to manage native forest invasibility
(PUBLIC LIBRARY SCIENCE, 2019)Pine invasion is a global threat that is occurring in native forests of diverse regions of the world. This process is arising in a scenario of rapid forest deforestation and degradation. Therefore, elucidate which forests ... -
Male group members are costly to plurally breeding Octodon degus females
(BRILL ACADEMIC PUBLISHERS, 2019)We report the results of a 6-year study of social (number of adult males/females, relatedness of females, communal litter size) and ecological (mean/CV of food abundance, soil hardness, burrow openings) factors influencing ... -
Metabolic potential and in situ transcriptomic profiles of previously uncharacterized key microbial groups involved in coupled carbon, nitrogen and sulfur cycling in anoxic marine zones
(WILEY, 2018)Anoxic marine zones (AMZs) impact biogeochemical cycles at the global scale, particularly the nitrogen cycle. Key microbial players from AMZs have been identified, but the majority remains unrecognized or uncharacterized. ... -
Microplastic ingestion cause intestinal lesions in the intertidal fish Girella laevifrons
(PERGAMON-ELSEVIER SCIENCE LTD, 2020)We exposed juvenile intertidal fish to different amounts of Poly(styrene-co-divinylbenzene) microplastics in their diet. We fed ten individuals with pellets containing 0.01 g, another ten fish with pellets containing 0.1 ... -
Monitoring the occurrence of microplastic ingestion in Otariids along the Peruvian and Chilean coasts
(Elsevier Inc., 2020-04)Repeated reports of microplastic pollution in the marine pinniped diet have emerged in the last years. However, only few studies address the drivers of microplastics presence and the potential implications for monitoring ... -
Multiple elements of soil biodiversity drive ecosystem functions across biomes
(NATURE PUBLISHING GROUP, 2020)The role of soil biodiversity in regulating multiple ecosystem functions is poorly understood, limiting our ability to predict how soil biodiversity loss might affect human wellbeing and ecosystem sustainability. Here, ... -
Multiple mating is linked to social setting and benefits the males in a communally rearing mammal
(OXFORD UNIV PRESS INC, 2019)Individuals in social species may mate with multiple opposite-sex individuals, including members of the same or different social groups. This variation may be linked to genetic benefits, where multiple mating decreases ... -
Neighbourhood landscape context shapes local species richness patterns across continents
(WILEY, 2023-06)Aim: Recent studies highlight the importance of linking landscape ecology and macroecology for a better understanding of broad-scale biodiversity patterns. The "landscape context effect" denotes that species responses and ... -
Next Generation Sequencing and mass spectrometry reveal high taxonomic diversity and complex phytoplankton-phycotoxins patterns in Southeastern Pacific fjords
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)In fjord systems, Harmful Algal Blooms (HABs) not only constitute a serious problem when affecting the wildlife and ecosystems, but also human health and economic activities related to the marine environment. This is mostly ... -
Non-trophic interactions strengthen the diversity-functioning relationship in an ecological bioenergetic network model
(PUBLIC LIBRARY SCIENCE, 2019)Ecological communities are undeniably diverse, both in terms of the species that compose them as well as the type of interactions that link species to each other. Despite this long recognition of the coexistence of multiple ... -
On the proportional abundance of species: Integrating population genetics and community ecology
(Nature Publishing Group, 2017)The frequency of genes in interconnected populations and of species in interconnected communities are affected by similar processes, such as birth, death and immigration. The equilibrium distribution of gene frequencies ... -
Ostreococcus tauri Luminescent Reporter Lines as Biosensors for Detecting Pollution From Copper-Mine Tailing Effluents in Coastal Environments
(FRONTIERS MEDIA SA, 2018)Phytoplankton cells are excellent biosensors for environmental monitoring and toxicity assessments in different natural systems. Green algae, in particular, appear to be more responsive to copper (Cu) disturbances. This ... -
Pharmacological iron-chelation as an assisted nutritional immunity strategy against Piscirickettsia salmonis infection
(BioMed Central Ltd., 2020-10)Salmonid Rickettsial Septicaemia (SRS), caused by Piscirickettsia salmonis, is a severe bacterial disease in the Chilean salmon farming industry. Vaccines and antibiotics are the current strategies to fight SRS; however, ... -
Phenology determines the robustness of plant-pollinator networks
(NATURE PUBLISHING GROUP, 2018)Plant-pollinator systems are essential for ecosystem functioning, which calls for an understanding of the determinants of their robustness to environmental threats. Previous studies considering such robustness have focused ... -
Pollinator declines and the stability of plant-pollinator networks
(Wiley-Blackwell, 2020-04)Population declines of pollinators constitute a major concern for the fate of biodiversity and associated ecosystem services in a context of global change. Massive declines of pollinator populations driven by habitat loss, ... -
Potential distribution model of Leontochir ovallei using remote sensing data
(UNIV POLITECNICA VALENCIA, EDITORIAL UPV, 2019)Predicting the potential distribution of short-lived species with a narrow natural distribution range is a difficult task, especially when there is limited field data. The possible distribution of L. ovallei was modeled ... -
