By contrasting this eco-evolutionary conceptual background with the current state of biodiversity modelling, we then identify the most important limitations, including available data, approaches to quantitative analyses and associated eco-evolutionary theory.

We consider biodiversity models to be any model that makes predictions for biodiversity (including species occurrences or …Yet global trends in biodiversity continue to decline. While the Convention on Biological Diversity has long recognised the importance of biodiversity and the need to conserve and sustainably use it, two of the 17 Sustainable Development Goals now explicitly focus on terrestrial and on marine ecosystems. The OECD provides analysis and good ...The biodiversity modelling community needs to more consistently follow this path and report and communicate the variability resulting from the different options in biodiversity models (e.g. SDMs, dispersal scenarios) and input data (e.g. GCM, RCP). However, the range of biodiversity model types, algorithms, input data or …
A third of high-risk areas are in high-biodiversity regions and a fifth are in low- and lower-middle-income areas, according to environmental modelling combined with pesticide application data.The worldwide variation in vegetation height is fundamental to the global carbon cycle and central to the functioning of ecosystems and their biodiversity. Geospatially explicit and, ideally, highly resolved information is required to manage terrestrial ecosystems, mitigate climate change, and prevent biodiversity loss. Here, we present the first global, wall-to …Abstract. Species distribution models (SDMs) are increasingly used in conservation and land-use planning as inputs to describe biodiversity patterns. These models can be built in different ways, and decisions about data preparation, selection of predictor variables, model fitting, and evaluation all alter the resulting predictions.We then used the updated model to project terrestrial biodiversity intactness from 2015 to 2050 as a function of land use and climate changes corresponding with the selected scenarios. We estimated a global area-weighted mean MSA of 0.56 for 2015. Biodiversity intactness declined in all three scenarios, yet the decline was smaller in the ...Biodiversity offsets are measurable conservation outcomes designed to compensate for adverse and unavoidable impacts of projects, in addition to prevention and mitigation measures already implemented.

We identify a variety of promising advances for incorporating this duality into commonly applied biodiversity modelling approaches and …Any SDM or biodiversity analysis starts with the conceptualisation of one or several underlying questions and related hypotheses. These conceptual considerations should be summarised in the Overview section, which captures the skeleton of the analyses, providing enough information for readers to understand the model setup and workflow (Guisan and Zimmermann 2000, Austin 2002, 2007).Biodiversity loss and climate change interact in many ways, reflecting two sides of the same problem: humanity’s unsustainable relationship with the natural world.

These sampling challenges raised by Araújo and Guisan in their 2006 publication have largely been met by methods to reduce sample bias, and by improved tools to access and clean biodiversity data, and to define modelling extent.
