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: 2020-10-18
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: 2020-10-15
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: 2020-10-15
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: 2020-10-15
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 [...]
