Multi-replicated enrichment communities as a model system in microbial ecology
Published: 2021-01-25
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology
Recent advances in robotics and affordable genomic sequencing technologies have made it possible to establish and quantitatively track the assembly of enrichment communities in high-throughput. By conducting community assembly experiments in up to thousands of synthetic habitats, where the extrinsic sources of variation among replicates can be controlled, we can now study the reproducibility and [...]
Complex environments alter competitive dynamics in fungi
Published: 2021-01-20
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Competition is a key biotic factor that often structures natural communities. Many attempts to disentangle how competition shapes natural communities have relied on experiments on simplified systems or through simple mathematical models. But these simplified approaches are limited in their ability to represent the complexity seen in more natural settings. Here, we considered the competitive [...]
Collecting eco-evolutionary data in the dark: Impediments to subterranean research and how to overcome them
Published: 2020-12-22
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
(1) Caves and other subterranean habitats fulfill the requirements of experimental model systems to address general questions in ecology and evolution. Yet, the harsh working conditions of these environments and the uniqueness of the subterranean organisms have challenged most attempts to pursuit standardized research (2) Two main obstacles have synergistically hampered previous attempts. First, [...]
Computer vision, machine learning, and the promise of phenomics in ecology and evolutionary biology
Published: 2020-12-17
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
For centuries, ecologists and evolutionary biologists have used images such as drawings, paintings and photographs to record and quantify the shapes and patterns of life. With the advent of digital imaging, biologists continue to collect image data at an ever-increasing rate. This immense body of data provides insight into a wide range of biological phenomena, including phenotypic trait [...]
Space-for-time inferences about range-edge dynamics of tree species can be influenced by sampling biases
Published: 2020-12-07
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Differences between the distributions of tree saplings and adults in geographic or niche space have been used to infer climate change effects on tree range dynamics. Previous studies have reported narrower latitudinal or climatic niche ranges of juvenile trees compared to adults, concluding that tree ranges are contracting, contradicting climate-based predictions. However, more comprehensive [...]
Land use-induced spillover: priority actions for protected and conserved area managers

Earth systems are under ever greater pressure from human population expansion and intensifying natural resource use. Consequently, novel micro-organisms that cause disease are emerging, dynamics of pathogens in wildlife are altered by land use change bringing wildlife and people in closer contact. We provide a brief overview of the processes governing ‘land use-induced spillover’, emphasising [...]
Combining surveys and on-line searching volumes to analyze public awareness about invasive alien species: a case study with the invasive Asian yellow-legged hornet (Vespa velutina) in Italy
Published: 2020-11-12
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology, Other Life Sciences
The Asian yellow-legged hornet (Vespa velutina) has been invading Italy since 2013, and it was subjected to management projects aimed at counteracting its spread and raising awareness about its impacts. In autumn 2019, we administered an on-line questionnaire to a convenience sample of 358 beekeepers in Italy. The questionnaire asked them about their sources of information about V. velutina, [...]
SVD entropy reveals the high complexity of ecological networks
Published: 2020-11-02
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Quantifying the complexity of ecological networks has remained elusive. Primarily, complexity has been defined on the basis of the structural (or behavioural) complexity of the system. These definitions ignore the notion of physical complexity, which can measure the amount of information contained in an ecological network, and how difficult it would be to compress. We present relative rank [...]
Introduced Vespa velutina does not replace native Vespa crabro and Vespula species
Published: 2020-11-02
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology, Population Biology
Alien species invasion could lead to the replacement of native species with similar ecological requirements. Vespa velutina is an invasive hornet recently established in Europe, that is raising concern due to the associated economic and ecological impacts toward managed and wild pollinators besides to the potential competition and replacement of native wasp species. This led to the inclusion of [...]
Shifts between cooperation and antagonism driven by individual variation: A systematic synthesis review
Published: 2020-10-28
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
The outcomes of interspecific and intraspecific ecological interactions can be considered to fall along continua from cooperative (mutually beneficial) to antagonistic (detrimental to one or both parties). Furthermore, the position of an interaction outcome along the continuum, for example whether a symbiont provides net costs or benefits to its host, or whether two conspecifics cooperatively [...]
Urban biodiversity and the importance of scale
Published: 2020-09-07
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Many ecological and evolutionary processes are affected by urbanization, but cities vary by orders of magnitude in their human population size and areal extent. To quantify and manage urban biodiversity we must understand both how biodiversity scales with city size, and how ecological, evolutionary, and socioeconomic drivers of biodiversity scale with city size. We show how environmental abiotic [...]
Filling the Information Gap in Meta-Ecosystem Ecology
Published: 2020-08-31
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Fluxes of matter, energy, and information over space and time contribute to ecosystems’ functioning. The meta-ecosystem framework addresses the dynamics of ecosystems linked by these fluxes, however, to date, meta-ecosystem research focused solely on fluxes of energy and matter, neglecting information. This is problematic due to organisms’ varied responses to information, which influence local [...]

Published: 2020-08-31
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
The range-wide management of the jaguar (Panthera onca) depends upon maintaining core populations connected through multi-national, transboundary cooperation, which is dependent upon understanding the movement ecology and space use of jaguars throughout their range. Using 117 telemetry trajectories from 12 ecoregions, we examined the landscape-level environmental and anthropogenic factors related [...]
VIRUS-HOST RELATIONSHIPS: AN OVERVIEW
Published: 2020-08-30
Subjects: Agriculture, Ecology and Evolutionary Biology, Life Sciences, Microbiology, Other Ecology and Evolutionary Biology, Virology
In order to survive in nature, different pathogens follow different procedures to manipulate their host plants for the pathogen favor. Plant viruses are not an exception of this rule. They are often found to alter the host plant traits in the way that affects the community of organisms in the host plant as well as the vectoring insects. It has been indicated that virus-infected plants are more [...]
