TLDR
In this paper, the authors combined occurrences and environment data in ecological niche models to assess suitable areas for the two species of African bush mango trees (Irvingia gabonensis and I. wombolu).Abstract:
Cultivation of priority plant species ensures their sustainable management. African bush mango trees (Irvingia gabonensis and I. wombolu) are the most exploited Irvingiaceae species. Experts disagree on the status of these very similar taxa, as taste remains the only character by which they can be distinguished in the field. We combined occurrences and environment data in ecological niche models to assess suitable areas for the two species. Irvingia gabonensis presented a wider occurrence area due to cultivation across contrasting ecological areas. Irvingia wombolu does not appear to be cultivated and only occurred in southwestern Togo. These differences in range is likely determined by phenological limitations of I. wombolu, reinforced by differences in local management systems, thus confirming the failure of market development to impact useful plant species’ conservation significantly. Highly suitable areas for I. wombolu were in the Volta Forest, where I. gabonensis saw low suitability, while out of this inverse situation was observed, as regard environmental suitability. These differences are significant, implying different ecological adaptation. However, anthropogenic influences, related to domestication history, are also important. Therefore, updated genetic investigations and field trials in contrasting ecological areas are required for understanding the origin of differences between these two forms.read more

Valère Kolawolé Salako,Romaric Vihotogbé,Romaric Vihotogbé,Thierry D. Houehanou,Idelphonse Akoeugnigan Sode,Romain Glèlè Kakaï +5 more
TL;DR: In this article, the authors combined geostatistical and SDM techniques to assess the current tree density spatial pattern and its relationship with bioclimatic zone (humid, sub-humid and semi-arid), land-use type (protected areas vs. agrosystems), and present-day and future distributions of suitable habitats under low-RCP4.5 and high RCP8.5 emissions scenarios for Borassus aethiopum.

TL;DR: It was found that methods specifically designed for collinearity, such as latent variable methods and tree based models, did not outperform the traditional GLM and threshold-based pre-selection and the value of GLM in combination with penalised methods and thresholds when omitted variables are considered in the final interpretation.

Dynamics of Land-Use and Land-Cover Change in Tropical Regions
TL;DR: In this article, the authors highlight the complexity of land-use/cover change and propose a framework for a more general understanding of the issue, with emphasis on tropical regions, and argue that a systematic analysis of local-scale land use change studies, conducted over a range of timescales, helps to uncover general principles that provide an explanation and prediction of new land use changes.
