Climate requirements for cultivated Liberica coffee (Coffea liberica) and consequences for its use and development as a crop species

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The global coffee industry, supporting 25 million smallholder farmers, is vulnerable to climate change. Diversifying the coffee species portfolio beyond Arabica and robusta is a promising intervention. Liberica coffee could provide adaptive capacity, although its climate parameters for cultivation are poorly known.

A synthetic eco‐evolutionary proposal for the conservation of wild relatives of the olive tree

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Crop wild relatives (CWR) are valuable sources of genetic diversity for plant breeding. However, the identification of wild untapped genetic resources (i.e., unexploited in crops) is not always straightforward. We propose a methodology to guide the identification and conservation of these resources that integrates both genetic

Conditioning moments of singular measures for entropy maximization II: Numerical examples

open access: yes, 2015
If moments of singular measures are passed as inputs to the entropy maximization procedure, the optimization algorithm might not terminate. The framework developed in our previous paper demonstrated how input moments of measures, on a broad range of ...

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Prediction of the spatial distribution of Alternanthera philoxeroides in China based on ArcGIS and MaxEnt

open access: yesGlobal Ecology and Conservation, 2020
As an invasive alien species, Alternanthera philoxeroides has spread rapidly in China since its invasion, which has caused serious harm to the ecological environment and substantial economic losses.

Climate change‐driven expansion of goosegrass highlights risks to global food production

open access: yesPest Management Science, EarlyView.
Climate change is expanding the climatic suitability of Eleusine indica into temperate agricultural regions, increasing its overlap with major soybean and maize production areas. These findings highlight a growing global threat to food security and the need for proactive weed management strategies.

Explicit probabilistic models for databases and networks

open access: yes, 2009
Recent work in data mining and related areas has highlighted the importance of the statistical assessment of data mining results. Crucial to this endeavour is the choice of a non-trivial null model for the data, to which the found patterns can be ...
