Accounting for seed rain and other confounders reveals which ecosystems are most susceptible to alien conifer establishment
Published: 2021-05-10
Subjects: Ecology and Evolutionary Biology, Life Sciences
1. Plantations of alien conifer species are common worldwide, and set to become even more prevalent in coming decades. To minimize the rate at which their offspring --- so-called "wildlings" --- colonize surroundings, and reduce the burden of conifer plantations on native ecosystems, managers need to know which ecosystems are most and least susceptible. 2. We compared how likely wildlings are to [...]
Utilizing Principles of Biodiversity Science to Guide Soil Microbial Communities for Sustainable Agriculture
Published: 2021-05-10
Subjects: Agriculture, Biology, Ecology and Evolutionary Biology, Life Sciences
While the positive relationship between plant biodiversity and ecosystem functioning (BEF) is relatively well-established, far less in known about the extent to which this relationship is mediated via below-ground microbial responses to plant diversity. Limited evidence suggests that the diversity of soil microbial communities is sensitive to plant community structure, and that diverse soil [...]
Male age alone predicts paternity success under sperm competition when effects of age and past mating effort are experimentally separated
Published: 2021-05-10
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Other Ecology and Evolutionary Biology
Older males often perform poorly under post-copulatory sexual selection. It is unclear, however, whether reproductive senescence is due to male age itself or the accumulated costs of the higher lifetime mating effort that is usually associated with male age. To date, very few studies have accounted for male mating history when testing for the effect of male age on sperm traits, and none test how [...]
Comment on ‘Carbon intensity of corn ethanol in the United States: state of the science’
Published: 2021-05-06

Scully et al [1] in their recent contribution review and revise past life cycle assessments (LCAs) of corn-grain ethanol’s carbon (C) intensity to suggest that a current ‘central best estimate’ is considerably less than all prior estimates. Their conclusion emerges from selection and recombination of sector-specific greenhouse gas emission predictions from disparate studies in a way that [...]
Species’ traits drive amphibian tolerance to anthropogenic habitat modification
Published: 2021-05-05
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Anthropogenic habitat modification is accelerating, threatening the world’s biodiversity. Understanding species’ responses to anthropogenic modification is vital for halting species’ declines. However, this information is lacking for globally threatened amphibians, informed primarily by small community-level studies. We integrated >126,000 verified citizen science observations of frogs, with a [...]
Quantifying the checks and balances of decentralised governance systems for adaptive carnivore management
Published: 2021-05-05
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Population Biology
1. Recovering or threatened carnivore populations are often harvested to minimise their impact on human activities, such as livestock farming or game hunting. Increasingly, harvest quota decisions involve a set of scientific, administrative and political institutions operating at national and sub-national levels whose interactions and collective decision-making aim to increase the legitimacy of [...]
Implementing network approaches to understand the socioecology of human-wildlife interactions
Published: 2021-05-05
Subjects: Animal Sciences, Anthropology, Behavior and Ethology, Biological and Physical Anthropology, Biology, Ecology and Evolutionary Biology, Life Sciences, Social and Behavioral Sciences
Human population expansion into wildlife habitats has increased interest in the behavioral ecology of human-wildlife interactions. To date, however, the socio-ecological factors that determine whether, when or where wild animals take risks by interacting with humans and anthropogenic factors still remains unclear. We adopt a comparative approach to address this gap, using social network analysis [...]
The economic value of fisheries, blue carbon, and nutrient cycling in global marine forests
Published: 2021-04-29
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Marine Biology
Underwater kelp forests have provided valuable ecosystem services for millennia. However, the global economic value of those services is largely unresolved. Kelp forests are also diminishing globally and efforts to manage these valuable resources are hindered without accurate estimates of the services kelp forests provide to society. We present the first global economic estimation of services - [...]
Warming in the upper San Francisco Estuary: Patterns of water temperature change from 5 decades of data
Published: 2021-04-29
Subjects: Climate, Ecology and Evolutionary Biology, Environmental Health and Protection, Environmental Monitoring, Environmental Sciences, Fresh Water Studies, Life Sciences, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics, Terrestrial and Aquatic Ecology
Temperature is a key controlling variable from subcellular to ecosystem scales. Thus, climatic warming is expected to have broad impacts, especially in economically and ecologically valuable systems such as estuaries. The heavily managed upper San Francisco Estuary supplies water to millions of people and is home to fish species of high conservation, commercial, and recreational interest. Despite [...]
Increased adoption of best practices in ecological forecasting enables comparisons of forecastability
Published: 2021-04-27
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Near-term iterative forecasting is a powerful tool for ecological decision support and has the potential to transform our understanding of ecological predictability. However, to this point, there has been no cross-ecosystem analysis of near-term ecological forecasts, making it difficult to synthesize diverse research efforts and prioritize future developments for this emerging field. In this [...]
Evolution of pathogen tolerance and emerging infections: A missing experimental paradigm
Published: 2021-04-27
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Population Biology
Researchers worldwide are repeatedly warning us against future zoonotic diseases resulting from mankind’s insurgence into natural ecosystems. The same zoonotic pathogens that cause severe infections in a human host fail to produce any disease outcome in their natural hosts. What precise features of the immune system enable natural reservoirs to carry these pathogens so efficiently? To understand [...]
Sex-specific behavioral syndromes allow the independent evolution of behavioral dimorphism
Published: 2021-04-27
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences
When selection differs by sex, the capacity for sexes to reach optimal phenotypes can be constrained by the shared genome of males and females. Because phenotypic traits are often correlated, this difference extends across multiple traits and underlying genetic correlations can further constrain evolutionary responses. Behaviors are frequently correlated as behavioral syndromes, and these [...]
Bringing Disciplines And People Together To Characterize The Plastic And Genetic Responses Of Molluscs To Environmental Change
Published: 2021-04-21
Subjects: Ecology and Evolutionary Biology, Life Sciences
Mollusks are remarkably diverse and are found across nearly all ecosystems, meaning that members of this ancient animal phylum provide a powerful means to study genomic-phenotype connections in a climate change framework. Recent advances in genomic sequencing technologies and genome assembly approaches finally allow the relatively cheap and tractable assembly of high-quality mollusk genome [...]
Primate malarias as a model for cross-species parasite transmission
Published: 2021-04-21
Subjects: Ecology and Evolutionary Biology, Life Sciences
Parasites regularly switch into new host species, representing a disease burden and conservation risk to the hosts. The distribution of these parasites also gives insight into characteristics of ecological networks and genetic mechanisms of host-parasite interactions. Some parasites are shared across many species, whereas others tend to be restricted to hosts from a single species. Understanding [...]
Terminology use in animal personality research: a self-report questionnaire and a systematic review
Published: 2021-04-21
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
Whether animal personality studies provide insights of broader evolutionary and ecological relevance to the field of behavioural ecology is frequently questioned. One of the sources of controversy is the vast, but often vague terminology present in the field. From a statistical perspective, animal personality is defined as among-individual variance in behaviour. However, numerous conceptual [...]
