Two novel azaspiracids from Azadinium poporum, and a comprehensive compilation of azaspiracids produced by Amphidomataceae, (Dinophyceae)
(ELSEVIER SCIENCE BV, 2019)Two novel azaspiracids (AZA) with a molecular mass of 869 Da were found in Pacific strains of Azadinium poporum and characterized by tandem mass spectrometry and high resolution mass spectrometry (HRMS). One compound, ... -
Changes in belowground biodiversity during ecosystem development
(NATL ACAD SCIENCES, 2019)Belowground organisms play critical roles in maintaining multiple ecosystem processes, including plant productivity, decomposition, and nutrient cycling. Despite their importance, however, we have a limited understanding ... -
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 ... -
Temporal variation in the influence of forest succession on caterpillar communities: A long-term study in a tropical dry forest
(WILEY, 2019)Forest succession can influence herbivore communities through changes in host availability, plant quality, microclimate, canopy structure complexity and predator abundance. It is not well known, however, if such influence ... -
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 ... -
Is there spatial variation in phenotypic selection on floral traits in a generalist plant-pollinator system?
(SPRINGER, 2019)The selective role of pollinators on the floral phenotype has been identified as the main force behind angiosperm diversification. However, in generalized plant-pollinator interactions this association may not be that ... -
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 ... -
Disentangling demographic co-effects of predation and pollution on population dynamics
(WILEY, 2019)In nature species react to a variety of endogenous and exogenous ecological factors. Understanding the mechanisms by which these factors interact and drive population dynamics is a need for understanding and managing ... -
Is the same pollinator species equally effective in different populations of the generalist herb Alstroemeria ligtu var. simsii?
(EDICIONES UNIV, CONCEPCION, 2019)En esta investigación estimamos la efectividad de polinización en tres poblaciones de Alstroemeria ligtu. Los resultados muestran que Lasia es el género de polinizador más frecuente, cuya efectividad varía entre poblaciones. ... -
Global phylogeography and ancient evolution of the widespread human gut virus crAssphage
(NATURE PUBLISHING GROUP, 2019)Microbiomes are vast communities of microorganisms and viruses that populate all natural ecosystems. Viruses have been considered to be the most variable component of microbiomes, as supported by virome surveys and examples ... -
The resolution-dependent role of landscape attributes in shaping macro-scale biodiversity patterns
(WILEY, 2019)Aim The aim was to assess whether and to what extent the role of local landscape attributes in shaping macroscopic biodiversity patterns is sensitive to spatial and thematic resolutions of land cover data. Location Sub-Saharan ... -
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 ... -
Community isolation drives lower fish biomass and species richness, but higher functional evenness, in a river metacommunity
(Wiley, 2020)The flow of individuals among communities and their interactions with local environmental filters are increasingly recognised as determinants of biodiversity patterns in riverine ecosystems. Both incoming dispersers and ... -
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 ... -
Exploring Perceived Well-Being from Urban Parks: Insights from a Megacity in Latin America
(Chile. Universidad Mayor, 2020)Urbanization has impacted biodiversity and ecosystems at a global scale. At the same time, it has been recognized as a driver of the physical and emotional gap between humans and nature. The lack of direct contact with ... -
Structure and vulnerability of the multi-interaction network in macrophyte-dominated lakes
(WILEY, 2020)The network approach is crucial to understand how ecosystems are structured and how they will respond to the disturbances (e.g. the current global change). We have recreated the multi-interaction network of a shallow ... -
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, ... -
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. ... -
The influence of soil age on ecosystem structure and function across biomes
(Chile. Universidad Mayor, 2020)The importance of soil age as an ecosystem driver across biomes remains largely unresolved. By combining a cross-biome global field survey, including data for 32 soil, plant, and microbial properties in 16 soil chronosequences, ... -
Soil microbial abundance and activity across forefield glacier chronosequence in the Northern Patagonian Ice Field, Chile
(Chile. Universidad Mayor, 2020)In recently deglaciated soils, microbial organisms drive soil transformations by increasing carbon (C) and nitrogen (N) pools while depleting available phosphorous (P), thus improving plant colonization and soil development. ...
