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 ...

Eco-evolutionary modelling is emerging as an important tool for understanding the causes of spatial biodiversity gradients: the ability of modelling experiments to independently control variables removes correlations between predictor variables that often hamper observational studies .

Biodiversity modelling is a key tool for the integration of these drivers and the predictions generated are essential, for example, for climate change forecast and conservation planning. However, the reliability of biodiversity models at the local scale remains poorly understood, especially in tropical species-rich areas, where they are required.

Loss of native habitat has been identified as one of the crucial drivers of the growing biodiversity crisis, acting toward the deleterious effects on individual fitness, functional diversity, changes in species richness and community structure.

These gaps are preventing the integration of multiple processes into biodiversity models.Sep 8, 2014 · Remote sensing techniques offer an opportunity to improve biodiversity modelling and prediction world-wide. Yet, to date, the weather station-based WorldClim data set has been the primary source of temperature and precipitation information used in correlative species distribution models.

As direct biodiversity mapping on farms is expensive, in terms of time and money, there is a demand for easy-to-use indicator-based models that allow food companies and authorities to time-effectively evaluate how farms perform in terms of biodiversity (Kempa and von Haaren Citation 2012; Kempa Citation 2013; Kramer et al.
