Qualitative and quantitative methods show stability in patterns of Cepaea nemoralis shell polymorphism in the Pyrenees over five decades
Published: 2020-12-01
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences
One of the emerging strengths of working with the land snail genus Cepaea is that historical collections can be compared against modern day samples, for instance to understand the impact of changing climate and habitat upon shell morph frequencies. However, one potential limitation is that prior studies scored shell ground colour by eye, usually in the field, into three discrete colours yellow, [...]
Mobilising molluscan models and genomes in biology
Published: 2020-11-24
Subjects: Biodiversity, Bioinformatics, Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Laboratory and Basic Science Research Life Sciences, Life Sciences
Molluscs are amongst the most ancient, diverse, and important of all animal taxa. Even so, no individual mollusc species has emerged as a broadly applied model system in biology. We here make the case that both perceptual and methodological barriers have played a role in the relative neglect of molluscs as research organisms. We then summarize the current application and potential of molluscs and [...]

Earth systems are under ever greater pressure from human population expansion and intensifying natural resource use. Consequently, novel micro-organisms that cause disease are emerging, dynamics of pathogens in wildlife are altered by land use change bringing wildlife and people in closer contact. We provide a brief overview of the processes governing ‘land use-induced spillover’, emphasising [...]
Diversity and structure of arbuscular mycorrhizal fungal commmunities and their chemical drivers across dryland habitats in Qatar
Published: 2020-11-22
Subjects: Biodiversity, Bioinformatics, Biotechnology, Desert Ecology, Ecology and Evolutionary Biology, Life Sciences
Qatar is largely characterized by a hyper-arid climate and low soil fertility, which combine to create a stressful soil environment for arbuscular mycorrhizal (AM) fungi. Here we present a study on AM fungi communities and their relationship to soil chemical characteristics. We used high-throughput seqeuncing technique for identifying AM fungal diversity and community composition from different [...]
Pandemics and biodiversity: applying lessons learned to conservation in the post-COVID-19 era
Published: 2020-11-12
Subjects: Biodiversity, Life Sciences
The COVID-19 pandemic has greatly restricted human activities, and wild species are seemingly thriving in human-dominated areas. However, we have little understanding of the consequences for biodiversity from governmental policies and socioeconomic changes in response to COVID-19, and their conservation significance. Understanding these impacts is a priority for setting effective conservation [...]
Using citizen science to measure recolonisation of birds after the Australian 2019-20 mega-fires
Published: 2020-11-09
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Large and severe fires (“mega-fires”) are increasing in frequency across the globe, often pushing into ecosystems that have previously had very long fire return intervals. The 2019-20 Australian bushfire season was one of the most catastrophic fire events on record. Almost 19 million hectares were burnt across the continent displacing and killing unprecedented numbers of native fauna, including [...]
Periodic monitoring of vampire bats and rabies: a new framework for animal restoration projects in the Neotropics
Published: 2020-11-06
Subjects: Biodiversity, Immunology and Infectious Disease, Immunology of Infectious Disease, Life Sciences
Nowadays, restoration project might lead to increased public engagement and enthusiasm for biodiversity and is receiving increased media attention in major newspapers, TED talks and the scientific literature. However, empirical research on restoration project is rare, fragmented, and geographically biased and long-term studies that monitor indirect and unexpected effects are needed to support [...]
Environmental conditions promote local segregation, but functional distinctiveness allow aggregation of catfishes in the Amazonian estuary
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 [...]
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 [...]
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 [...]
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 [...]
