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 [...]
Participatory mapping of aquatic invasive species: a demonstration in a coastal lagoon
Published: 2020-10-16
Subjects: Biodiversity, Life Sciences, Marine Biology, Other Life Sciences, Research Methods in Life Sciences
Aquatic Invasive species (AIS) are a growing driver of change across marine and freshwater ecosystems but spatially-explicit information is seldom available for supporting management actions and decision making. Here we conceived and tested a new participatory method to map the distribution of three invasive species (Callinectes sapidus, Procambarus clarkii and Oreochromis niloticus) in the [...]
Insights from regional and short-term biodiversity monitoring datasets are valuable. A Reply to Daskalova et al. 2020 EcoEvoRxiv doi:10.32942/osf.io/cg3zs
Published: 2020-10-16
Subjects: Biodiversity, Biology, Entomology, Life Sciences, Research Methods in Life Sciences
Reports of major losses in biodiversity have stimulated an increasing interest in temporal population changes, particularly in insects, which had received little attention in the past. Existing long-term datasets are often limited to a small number of study sites, few points in time, a narrow range of land-use intensities and only some taxonomic groups, or they lack standardized sampling. While [...]
Epigenetics and the success of invasive plants
Published: 2020-10-13
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences, Plant Sciences
Biological invasions impose ecological and economic problems on a global scale, but also provide extraordinary opportunities for studying contemporary evolution. It is critical to understand the evolutionary processes that underly invasion success in order to successfully manage existing invaders, and to prevent future invasions. As successful invasive species sometimes are suspected to rapidly [...]
Combining mesocosms with models to unravel the effects of global warming and ocean acidification on temperate marine ecosystems
Published: 2020-10-11
Subjects: Life Sciences, Marine Biology
Ocean warming and species exploitation have already caused large-scale reorganization of biological communities across the world. Accurate projections of future biodiversity change require a comprehensive understanding of how entire communities respond to global change. We combined a time-dynamic integrated food web modelling approach (Ecosim) with a community-level mesocosm experiment to [...]
Accounting for year effects and sampling error in temporal analyses of population and biodiversity change - Response to Seibold et al. 2019 “Arthropod decline in grasslands and forests is associated with landscape-level drivers”
Published: 2020-10-11
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences, Population Biology
An accumulating number of studies are reporting severe biomass, abundance and/or species richness declines of insects (Hallmann et al., 2017; Lister & Garcia, 2018; Seibold et al., 2019; Sánchez-Bayo & Wyckhuys, 2019). Collectively these studies aim to quantify the net change in invertebrate populations and/or community composition over time and to establish whether such changes can be [...]
Limited effect of COVID-19 on the 2020 fire season in Mediterranean Europe
Published: 2020-10-10
Subjects: Forest Sciences, Life Sciences
In a recent study, Rodrigues et al. (2020) analyze the impact of COVID-19 on fire activity. During this year’s pandemic we have experienced extreme fire activity in many areas worldwide including Siberia (McCarty et al., 2020), western US (Pickrell and Pennisi, 2020), and different Latin American countries including Argentina, Bolivia or Paraguay. Interestingly, the authors argue that COVID-19 [...]
Phylogenetic Comparative Methods: A User’s Guide for Paleontologists
Published: 2020-10-05
Subjects: Ecology and Evolutionary Biology, Life Sciences
Recent advances in statistical approaches called Phylogenetic Comparative Methods (PCMs) have provided paleontologists with a powerful set of analytical tools for investigating evolutionary tempo and mode in fossil lineages. However, attempts to integrate PCMs with fossil data often present workers with practical challenges or unfamiliar literature. In this paper, we present guides to the theory [...]
Reported individual costs and benefits of sharing open data among Canadian academic faculty in ecology and evolution
Published: 2020-10-05
Subjects: Ecology and Evolutionary Biology, Life Sciences
Open data facilitate reproducibility and accelerate scientific discovery but are hindered by perceptions that researchers bear costs and gain few benefits from publicly sharing their data, with limited empirical evidence to the contrary. We surveyed 140 faculty members working in ecology and evolution across Canada’s top 20-ranked universities and found that more researchers report benefits [...]
Is Human Society an Organism Made of Many Animals?
Published: 2020-10-04
Subjects: Life Sciences, Other Sociology, Social and Behavioral Sciences, Sociology
Social organism theories of the past have defined human societies as “biological organisms”, similar to animals or plants. This present work draws from the recent technological breakthroughs in both biology and astronomy to define the worldwide human society as a “multizoa organism”, i.e. an organism made of many animals. The paper then puts forth the idea that as a multizoa organism, human [...]
Including Rural America in academic conservation science
Published: 2020-10-03
Subjects: Ecology and Evolutionary Biology, Environmental Law, Law, Life Sciences, Other Life Sciences
Entrenched political partisanship in the United States has placed long-standing constraints on conservation policy and climate change legislation. These barriers persist, demanding fresh insights into the ways that conservation has become a victim of political polarization, and pathways for encouraging bipartisan support for climate change and other U.S. conservation policies. We suggest three [...]
Impacts of human disturbance in marine mammals: Do behavioral changes translate to disease consequences? Full methods and Analysis
Published: 2020-10-01
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Population Biology
Humans have been altering wildlife habitats and wildlife behavior worldwide at an accelerated pace in recent decades. While it is well-understood how human-induced behavioral changes affect infectious disease risk in terrestrial wildlife, less is known in marine life. Here we examine this link in marine mammal populations by (1) conducting a systematic literature review to determine how human [...]
Understanding biological resilience, from genes to ecosystems
Published: 2020-10-01
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
The natural world is under unprecedented and accelerating pressure. Much work on understanding resilience to local and global environmental change has, so far, focussed on ecosystems. However, understanding a system’s behaviour requires knowledge of its component parts and their interactions. Here we present a framework for understanding ‘biological resilience’, or the processes that enable [...]
Synergistic impacts of anthropogenic fires and aridity on plant diversity in the Western Ghats: Implications for management of ancient social-ecological systems
Published: 2020-10-01
Subjects: Biodiversity, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics, Sustainability
Identifying the impacts of anthropogenic fires on biodiversity is imperative for human-influenced tropical rainforests because: i) these ecosystems have been transformed by human-induced fires for millennia; and ii) their effective management is essential for protecting the world’s terrestrial biodiversity in the face of global environmental change. While several short-term studies elucidate the [...]
