*Context* Pattern-based spatial analysis provides methods to describe and quantitatively compare spatial patterns for categorical raster datasets. It allows for spatial search, change detection, and clustering of areas with similar patterns. *Objectives* We developed an R package **motif** as a set of open-source tools for pattern-based spatial analysis. *Methods* This package provides [...]
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 [...]
Recent advances of quantitative modeling to support invasive species eradication on islands
Published: 2020-09-08
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Natural Resources and Conservation, Physical Sciences and Mathematics
The eradication of invasive species from islands is an important part of managing these ecologically unique and at-risk regions. Island eradications are complex projects and mathematical models play an important role in supporting efficient and transparent decision-making. In this review we cover the past applications of modelling to island eradications, which range from large-scale [...]

FIRED (Fire Events Delineation): An open, flexible algorithm & database of US fire events derived from the MODIS burned area product (2001-19)
Published: 2020-06-27
Subjects: Ecology and Evolutionary Biology, Environmental Monitoring, Environmental Sciences, Life Sciences, Other Ecology and Evolutionary Biology, Physical Sciences and Mathematics
Harnessing the fire data revolution, i.e., the abundance of information from satellites, government records, social media, and human health sources, now requires complex and challenging data integration approaches. Defining fire events is key to that effort. In order to understand the spatial and temporal characteristics of fire, or the classic fire regime concept, we need to critically define [...]
What we can learn from the parallels between the COVID-19 and the future climate change crises
Published: 2020-04-12
Subjects: Environmental Sciences, Life Sciences, Physical Sciences and Mathematics
The ongoing COVID-19 outbreak pandemic is now a global crisis. It has caused 1.6+ million confirmed cases and 100 000+ deaths at the time of writing and triggered unprecedented preventative measures that have put a substantial portion of the global population under confinement, imposed isolation, and established ‘social distancing’ as a new global behavioral norm. The COVID-19 crisis has affected [...]
Understanding the tripartite approach to Bayesian divergence time estimation
Published: 2020-04-08
Subjects: Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics
Placing evolutionary events in the context of geological time is a fundamental goal in paleobiology and macroevolution. In this article we describe the tripartite model used for Bayesian estimation of time calibrated phylogenetic trees. The model can be readily separated into its component models: the substitution model, the clock model and the tree model. We provide an overview of the most [...]
StableClim, continuous projections of climate stability from 21000 BP to 2100 CE at multiple spatial scales
Published: 2020-02-22
Subjects: Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Other Ecology and Evolutionary Biology, Other Environmental Sciences, Physical Sciences and Mathematics
Paleoclimatic data are used in eco-evolutionary models to improve knowledge of biogeographical processes that drive patterns of biodiversity through time, opening windows into past climate–biodiversity dynamics. Applying these models to harmonised simulations of past and future climatic change can strengthen forecasts of biodiversity change. StableClim provides continuous estimates of climate [...]
Experimenting with the past to improve environmental monitoring programs
Published: 2019-10-14
Subjects: Agriculture, Biodiversity, Ecology and Evolutionary Biology, Environmental Monitoring, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics, Research Methods in Life Sciences
Long-term monitoring programs are a fundamental part of both understanding system dynamics and informing management decisions. However, monitoring programs not always designed to consider statistical power, site selection, or the full costs and benefits of monitoring. Further, data from monitoring programs with different goals and protocols are now being combined for comparative analyses. Key [...]

Received views of resilience span a broad conceptual and theoretical terrain, with a diverse range of application domains and settings. In [...]
On the importance of the megabiota to the functioning of the biosphere
Published: 2019-06-15
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Natural Resources and Conservation, Other Ecology and Evolutionary Biology, Physical Sciences and Mathematics
A prominent signal of the Anthropocene is the extinction and population reduction of the megabiota – the largest animals and plants on the planet. However, we lack a predictive framework for the sensitivity of megabiota during times of rapid global change and how they impact the functioning of ecosystems and the biosphere. Here, we extend metabolic scaling theory and use global simulation models [...]
