The European Turtle Dove in the ecotone between woodland and farmland: multi-scale habitat associations and implications for the design of management interventions
Published: 2021-04-20
Subjects: Ecology and Evolutionary Biology, Life Sciences
The European Turtle Dove (turtle dove) is a globally threatened species that is undergoing a sustained and generalised decline across its breeding range, with habitat deterioration and loss suggested as the main driver. Here, we review the scientific literature on habitat associations across the European breeding range, in relation to turtle dove distribution, breeding numbers, nesting substrates [...]
Estimating complex ecological variables at high resolution in heterogeneous terrain using multivariate matching algorithms
Published: 2021-04-17
Subjects: Ecology and Evolutionary Biology, Life Sciences, Multivariate Analysis, Physical Sciences and Mathematics, Research Methods in Life Sciences, Statistics and Probability
1. Simulation models are valuable tools for estimating ecosystem structure and function under various climatic and environmental conditions and disturbance regimes, and are particularly relevant for investigating the potential impacts of climate change on ecosystems. However, because computational requirements can restrict the number of feasible simulations, they are often run at coarse scales or [...]
Sponges facilitate primary producers in a Bahamas seagrass system
Published: 2021-04-16
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology
Seagrass beds are important coastal ecosystems worldwide that are shaped by facilitative interactions. Recent theoretical work has emphasized the potential for facilitative interactions involving foundation species to be destabilized in the face of anthropogenic change. Consequently, it is important to identify which taxa facilitate seagrasses. In other ecosystems, sponges contribute to the [...]
Reefscape genomics: leveraging advances in 3D imaging to assess fine-scale patterns of genomic variation on coral reefs
Published: 2021-04-16
Subjects: Biology, Genetics and Genomics, Life Sciences, Marine Biology
Coral reefs across the world are undergoing rapid deterioration, and understanding the ecological and evolutionary processes that govern these ecosystems is critical to our ability to protect them. Molecular ecological studies have been instrumental in advancing such understanding, and while initially focused primarily on broad-scale patterns, they have gradually uncovered the prevalence of local [...]
COVID-19 and Small-scale fisheries in Africa: Impacts on livelihoods and the fish value chain in Cameroon and Liberia
Published: 2021-04-15
Subjects: Environmental Studies, Social and Behavioral Sciences
This study explores the emerging impacts of the COVID-19 pandemic on coastal small-scale fishing communities in Cameroon and Liberia, where we conducted qualitative interviews with small-scale fish harvesters, fish processors, traders, and consumers. We found that the implementation of COVID-19 safety and health protocol initiatives impacted the entire fish value chain, which contributed to [...]
El histórico Acuerdo de Escazú: una oportunidad para integrar democracia, derechos humanos y conservación transfronteriza
Published: 2021-04-14
Subjects: Life Sciences, Other Life Sciences
América Latina y el Caribe (ALC) es una de las regiones con mayor biodiversidad, sin embargo, esta se encuentra amenazada por la sobreexplotación de recursos naturales y por conflictos sociales internos. En el 2018, 33 países de la región ALC fueron invitados a firmar y ratificar el histórico Acuerdo de Escazú, el cual es el primer acuerdo de carácter vinculante que integra de manera explícita [...]
Broad-scale Applications of the Raspberry Pi: A Review and Guide for Biologists
Published: 2021-04-13
Subjects: Biology, Biotechnology, Ecology and Evolutionary Biology, Life Sciences, Plant Sciences, Social and Behavioral Sciences
The field of biology has seen tremendous technological progress in recent years, fuelled by the exponential growth in processing power and high-level computing, and the rise of global information sharing. Low-cost single-board computers are predicted to be one of the key technological advancements to further revolutionise this field. So far, an overview of current uptake of these devices and a [...]
Spillback in the Anthropocene: the risk of human-to-wildlife pathogen transmission for conservation and public health

The SARS-CoV-2 pandemic has led to increased concern over transmission of pathogens from humans to animals (“spillback”) and its potential to threaten conservation and public health. To assess this threat, we reviewed published evidence of spillback events, including instances where spillback could threaten conservation and human health. We identified 97 verified examples of spillback, involving [...]
Understanding determinants of the intention to purchase rhino horn in Vietnam through the Theory of Planned Behaviour and the Theory of Interpersonal Behaviour
Published: 2021-04-12
Subjects: Psychology, Social and Behavioral Sciences, Social Psychology
Demand for rhino horn in Asian markets is driving a rhino poaching crisis in Africa. This study examined rhino horn demand using the theory of planned behaviour and the theory of interpersonal behaviour. We conducted a survey of 427 individuals in Hanoi, Vietnam, including 281 rhino horn users and 146 non-users. We empirically tested all constructs of the two theories predicting intention to [...]
Conserving rhinos by legal trade: Insights from a choice experiment on rhino horn consumers
Published: 2021-04-12
Subjects: Agricultural and Resource Economics, Economic Theory, Economics, Environmental Studies, Social and Behavioral Sciences
A legal rhino horn trade is suggested to reduce poaching. To examine this proposition we conducted a choice experiment with 345 rhino horn consumers in Vietnam investigating their preferences for legality, source, price and peer experience of medicinal efficacy as attributes in their decision to purchase rhino horn. We calculated consumers’ willingness to pay for each attribute level. Consumers [...]
Welcome to the Pyrocene: animal survival in the age of megafire
Published: 2021-04-10
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Planet Earth is entering the age of megafire, pushing ecosystems to their limits and beyond. While fire causes mortality of animals across vast portions of the globe, scientists are only beginning to consider fire as an evolutionary force in animal ecology. Here, we generate a series of hypotheses regarding animal responses to fire by adopting insights from the predator-prey literature. Fire is a [...]
Methods for testing publication bias in ecological and evolutionary meta-analyses
Published: 2021-04-09
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
1. Publication bias threatens the validity of quantitative evidence from meta-analyses as it results in some findings being overrepresented in meta-analytic datasets because they are published more frequently or sooner (e.g., ‘positive’ results). Unfortunately, methods to test for the presence of publication bias, or assess its impact on meta-analytic results, are unsuitable for datasets with [...]
BetaBayes - A Bayesian approach for comparing ecological communities
Published: 2021-04-09
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Physical Sciences and Mathematics, Statistics and Probability
Ecological communities change due to both natural and human factors. Distinguishing between the two is critical to ecology and conservation science. One of the most common approaches for modelling species composition changes is calculating Beta diversity indices and then relating index changes to covariates changes. The main difficulty with these analyses is that Beta diversity indices are paired [...]
Fungus-bacterium associations are widespread in fungal cultures isolated from a semi-arid natural grassland in Germany

We here report on a study that aimed at establishing a large soil-fungal culture collection spanning a wide taxonomic diversity and systematically screening the collection for bacterial associations.
Ecological mechanisms underlying aridity thresholds in global drylands
Published: 2021-04-02
Subjects: Desert Ecology, Ecology and Evolutionary Biology, Life Sciences
With ongoing climate change, the probability of crossing environmental thresholds promoting abrupt changes in ecosystem structure and functioning is higher than ever. In drylands (sites where it rains less than 60% of what is evaporated), recent research has shown how the crossing of three particular aridity thresholds (defining three consecutive phases, namely vegetation decline, soil disruption [...]
