Climate–land-use interactions shape tropical mountain biodiversity and ecosystem functions

Marcell K. Peters, +56 more
- 27 Mar 2019 - 
TL;DR: The study reveals that climate can modulate the effects of land use on biodiversity and ecosystem functioning, and points to a lowered resistance of ecosystems in climatically challenging environments to ongoing land-use changes in tropical mountainous regions.
Journal ArticleDOI

Predictors of elevational biodiversity gradients change from single taxa to the multi-taxa community level

TL;DR: This work quantifies cross-taxon consensus in diversity gradients and evaluates predictors of diversity from single taxa to a multi-taxa community level and points to the importance of temperature for diversification and species coexistence in plant and animal communities.
Journal ArticleDOI

Improving the accuracy of rainfall rates from optical satellite sensors with machine learning — A random forests-based approach applied to MSG SEVIRI

TL;DR: In this article, the authors investigated the potential of the random forests ensemble classification and regression technique to improve rainfall rate assignment during day, night and twilight (resulting in 24-hour precipitation estimates) based on cloud physical properties retrieved from Meteosat Second Generation (MSG) Spinning Enhanced Visible and InfraRed Imager (SEVIRI) data.
Journal ArticleDOI

Evaluating machine learning approaches for the interpolation of monthly air temperature at Mt. Kilimanjaro, Tanzania

TL;DR: A combined Cubist and residual kriging approach can be considered the best solution for predicting spatial temperature patterns based on a network of temperature observation plots across the southern slopes of Mt. Kilimanjaro.
Journal ArticleDOI

Mapping Daily Air Temperature for Antarctica Based on MODIS LST

TL;DR: The performance of a simple linear regression model to predict T a i r from LST was compared to the performance of three machine learning algorithms: Random Forest, generalized boosted regression models (GBM) and Cubist and auxiliary predictor variables were tested in these models.
