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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
Small eukaryotic phytoplankton communities in tropical waters off Brazil are dominated by symbioses between Haptophyta and nitrogen-fixing cyanobacteria
(NATURE PUBLISHING GROUP, 2018)Symbioses between eukaryotic algae and nitrogen-fixing cyanobacteria have been recognized in recent years as a key source of new nitrogen in the oceans. We investigated the composition of the small photosynthetic eukaryote ... -
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. ... -
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 ... -
Temperature modulates Fischerella thermalis ecotypes in Porcelana Hot Spring
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2018)In the Porcelana Hot Spring (Northern Patagonia), true-branching cyanobacteria are the dominant primary producers in microbial mats, and they are mainly responsible for carbon and nitrogen fixation. However, little is known ... -
Distinctive Archaeal Composition of an Artisanal Crystallizer Pond and Functional Insights Into Salt-Saturated Hypersaline Environment Adaptation
(FRONTIERS MEDIA SA, 2018)Hypersaline environments represent some of the most challenging settings for life on Earth. Extremely halophilic microorganisms have been selected to colonize and thrive in these extreme environments by virtue of a broad ... -
High similarity in the microbiota of cold-water sponges of the Genus Mycale from two different geographical areas
(PEERJ INC, 2018)Sponges belonging to genus Mycale are common and widely distributed across the oceans and represent a significant component of benthic communities in term of their biomass, which in many species is largely composed by ... -
Species traits and network structure predict the success and impacts of pollinator invasions
(NATURE PUBLISHING GROUP, 2018)Species invasions constitute a major and poorly understood threat to plant-pollinator systems. General theory predicting which factors drive species invasion success and subsequent effects on native ecosystems is particularly ...
