Transgenerational effects of temperature fluctuations in Arabidopsis thaliana
Published: 2020-11-10
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Population Biology
Plant stress responses can extend into the following generations, a phenomenon called transgenerational effects. Heat stress, in particular, is known to affect plant offspring, but we do not know to what extent these effects depend on the temporal patterns of the stress, and whether transgenerational responses are adaptive and genetically variable within species. To address these questions, we [...]
Heuristics for the sustainable harvest of wildlife in stochastic social-ecological systems
Published: 2020-11-06
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Sustainable wildlife harvest is challenging due to the complexity of uncertain social-ecological systems, and diverse stakeholder perspectives of sustainability. In these systems, semi-complex stochastic simulation models can provide heuristics that bridge the gap between highly simplified theoretical models and highly context-specific case-studies. Such heuristics allow for more nuanced [...]
Periodic monitoring of vampire bats and rabies: a new framework for animal restoration projects in the Neotropics
Published: 2020-11-06
Subjects: Biodiversity, Immunology and Infectious Disease, Immunology of Infectious Disease, Life Sciences
Nowadays, restoration project might lead to increased public engagement and enthusiasm for biodiversity and is receiving increased media attention in major newspapers, TED talks and the scientific literature. However, empirical research on restoration project is rare, fragmented, and geographically biased and long-term studies that monitor indirect and unexpected effects are needed to support [...]
Wolf depredation hotspots in France: Clustering analyses accounting for livestock availability
Published: 2020-11-06
Subjects: Agriculture, Animal Sciences, Ecology and Evolutionary Biology, Life Sciences, Zoology
Depredation hotspots are the main source of conflict between humans and large carnivores. When locating depredation hotspots, previous studies have not adjusted for livestock availability, making it impossible for managers to discriminate hotspots resulting from underlying livestock clustering from those due to other factors such as environmental factors. We studied hotspots of wolf depredation [...]
Tree taxon effects on the phenology of caterpillar abundance and biomass
Published: 2020-11-04
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Phenological shifts are well documented biological responses to warming. While many studies have focused on the mean timing of an event, there is growing appreciation that the height and width of the phenological distribution will also impact on species interactions. A temperate deciduous forest food chain of oak trees – arboreal caterpillars – insectivorous passerines has become paradigmatic in [...]
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 [...]
Workflow for constructing social networks from automated telemetry systems

Subjects: Animal Experimentation and Research, Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Research Methods in Life Sciences
1. Advances in datalogging technologies have provided a way to monitor the movement of individual animals at unprecedented spatial and temporal scales, both large and small. When used in conjunction with social network analyses, these data can provide insight into fine scale associative behaviors. The variety of technologies demand continuous progress in workflows to translate data streams from [...]
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 [...]
Environmental conditions promote local segregation, but functional distinctiveness allow aggregation of catfishes in the Amazonian estuary
Published: 2020-10-22
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Terrestrial and Aquatic Ecology
Cooccurrence patterns of species can appear through niche-related processes such as (i) environmental filtering matching specific sets of traits to a given environment, and (ii) limiting similarity selecting divergent functional traits to reduce niche overlap. Locally, both processes should act together to shape the distribution of species. We evaluated the importance of environmental variables [...]
Rock glaciers and related cold rocky landforms: overlooked climate refugia for mountain biodiversity
Published: 2020-10-19
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Mountains are global biodiversity hotspots where cold environments and their associated ecological communities are predicted to be threatened by climate warming. Considerable research attention has been devoted to understanding the ecological effects of alpine glacier and snowfield recession. However, much less attention has been given to identifying climate refugia in mountain ecosystems where [...]

Anthropogenic land use change is the major driver of zoonotic pathogen spillover from wildlife to humans. In response to the global spread of the SARS-CoV-2 virus (the agent of COVID-19 disease), there have been renewed calls for landscape conservation as a disease preventive measure. While protected areas are a vital conservation tool for wildlands, more than 50% of habitable land is now [...]
Non-additive genetic effects induce novel phenotypic distributions in male mating traits of F1 hybrids
Published: 2020-10-16
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Hybridization is a source of phenotypic novelty and variation because of increased additive genetic variation. Yet, the roles of non-additive allelic interactions in shaping phenotypic mean and variance of hybrids have been underappreciated. Here we examine the distributions of male-mating traits in F1 hybrids via a meta-analysis of 3,208 effect sizes from 39 animal species pairs. Although [...]
