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 [...]
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: 2021-04-08
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: 2021-04-08
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
Published: 2021-04-07
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
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 [...]
Astatotilapia species (Teleostei, Cichlidae) from Malawi, Mozambique and Tanzania, excluding the basin of Lake Victoria.
Published: 2021-04-01
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
The haplochromine cichlid fauna of the rivers and smaller lakes of Tanzania and SE Africa are of key importance in understanding the origins and inter-relationships of the great lake cichlid radiations of Malawi, Tanganyika and Victoria. Prior to formal taxonomic investigations, here we present the results of investigations of the type specimens, identification of type localities and superficial [...]
Supporting actionable science for environmental policy: Advice for funding agencies from decision makers
Published: 2021-04-01
Subjects: Environmental Policy, Environmental Studies, Life Sciences, Public Affairs, Public Policy and Public Administration, Social and Behavioral Sciences
Successful incorporation of scientific knowledge into environmental policy and decisions is a significant challenge. Although studies on how to bridge the knowledge-action gap have grown rapidly over the last decade, few have investigated the roles, responsibilities, and opportunities for funding bodies to meet this challenge. In this study we present a set of criteria gleaned from interviews [...]
Contrasting climate velocity impacts in warm and cool locations show that effects of marine warming are worse in already warmer temperate waters
Published: 2021-04-01
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Population Biology, Terrestrial and Aquatic Ecology
Species responses to climate change are often measured at broad spatiotemporal scales, which can miss fine-scale changes that are relevant to conservation and fisheries management. We develop a scale-able geostatistical approach to assess how juvenile and adult fish distributions have been shaped by changes in bottom temperature and dissolved oxygen over a recent decade of warming in the [...]
Forest Conservation in Madagascar: Past, Present, Future
Published: 2021-04-01
Subjects: Biodiversity, Life Sciences
To be published in the upcoming book The New Natural History of Madagascar, edited by S. M. Goodman, published by Princeton University Press. A French translation of the chapter "Conservation des forêts à Madagascar : Passé, Présent, et Futur" is included at the end of the preprint. At this critical time for the future of Madagascar’s biodiversity, we first review the past: touching upon [...]
Global economic and diet transitions drove Latin American and Caribbean forest change during the first decade of the century.
Published: 2021-03-31
Subjects: Arts and Humanities, Environmental Sciences, Geography, Life Sciences, Natural Resources and Conservation, Physical and Environmental Geography, Physical Sciences and Mathematics, Social and Behavioral Sciences
Latin America and the Caribbean (LAC) contain more tropical high-biodiversity forest than the remaining areas of the planet combined, yet experienced more than a third of global deforestation during the first decade of the 21st century. While drivers of forest change occur at multiple scales, we examined forest change at the municipal and national scales integrated with global processes such as [...]
Weak but persistent provenance effects modulate the response of Quercus robur (Fagaceae) seedlings to elevated temperature
Published: 2021-03-25
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Background and aims Clinal variation in bud phenology and growth has repeatedly been reported in common garden experiments for many tree species. The response of the seedlings generated from such translocated trees has not been studied yet, despite its relevance regarding the role of transgenerational plasticity in the adaptation of long-living trees in the face of climate change. Here, we aim to [...]
Effects of wave-driven water flow on the fast-start escape response of juvenile coral reef damselfishes
Published: 2021-03-25
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Integrative Biology, Life Sciences
Fish often evade predators with a fast-start escape response. Studies typically examine this behaviour in still water despite water motion being an inherent feature of aquatic ecosystems. In shallow habitats, waves create complex flows that likely influence escape performance, particularly in small fishes with low absolute swimming speeds relative to environmental flows. I examined how [...]
Applying conservation reserve design strategies to define ecosystem monitoring priorities
Published: 2021-03-24
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
In an era of unprecedented ecological upheaval, accurately monitoring ecosystem change at large spatial scales and over long-time frames is an essential to effective environmental management and conservation. However, economic limitations often preclude revisiting entire monitoring networks at a high enough frequency to accurately detect ecological changes. Thus, a prioritisation strategy is [...]
Early predation risk shapes adult learning and cognitive flexibility
Published: 2021-03-24
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences
Predation risk during early ontogeny can impact developmental trajectories and permanently alter adult phenotypes. Such phenotypic plasticity often leads to adaptive changes in traits involved in anti-predator responses. While plastic changes in cognition may increase survival, it remains unclear whether early predation experience shapes cognitive investment and drives developmental plasticity in [...]
