- Projected temperature increases may require shifts in the growing season of cool-season crops and the growing locations of warm-season crops. In California’s Mediterranean climate, cool season crops will have to shift in time, and warm-season crops in place.
- A “Mega Population” of the Wild Potato Species Solanum fendleri. Large population, safe, accessible and very diverse. Who needs genebanks, right?
- Survival of Solanum jamesii Tubers at Freezing Temperatures. Very unusual trait in both the crop and the wild relatives, apparently.
- Diversity and uses of enset [Ensete ventricosum (Welw.) Cheesman] varieties in Angacha district, Southern Ethiopia: call for taxonomic identifications and conservation. 55 varieties in 75 homegardens, 88 in the field genebank, many in only one or the other.
- Impact of Climate Change on the Diversity and Distribution of Enset (Ensete ventricosum (Welw) Cheesman) in Ethiopia: A Review. Some are moving, some are dying. I guess we really need in vitro and cryo after all.
- Filling the gaps in gene banks: Collecting, characterizing and phenotyping wild banana relatives of Papua New Guinea. Much diversity of banana ancestor still not in genebanks, but people are on the job.
- Modeling the Impact of Crop Diseases on Global Food Security. Genetic diversity is not enough.
- What natural variation can teach us about resistance durability. That genetic diversity is not enough, apparently.
- Wheat blast: a new threat to food security. We have the genes to fight it, but they won’t be enough.
- Limited haplotype diversity underlies polygenic trait architecture across 70 years of wheat breeding. I hope at least those genes can be found in this MAGIC population based on European bread wheat varieties from the past few decades.
- Potential Short-Term Memory Induction as a Promising Method for Increasing Drought Tolerance in Sweetpotato Crop Wild Relatives [Ipomoea series Batatas (Choisy) D. F. Austin]. Wild sweet potatoes have the genes to remember drought stress, and hence cope with it better. Will they be enough though?
- Ecological pest control fortifies agricultural growth in Asia–Pacific economies. Biological control has been worth USD 15-20 billion a year for non-rice crops over the past 100 years across 23 countries. But how much is the interaction with genetic diversity worth?
- Evaluation of the contribution of teosinte to the improvement of agronomic, grain quality and yield traits in maize (Zea mays). Wild relative not just a source of stress resistance, could be useful for yield potential too.
- “It may also have prevented churchgoers from falling asleep”: southernwood, Artemisia abrotanum L. (fam. Asteraceae), in the church bouquet, and its contemporary presence as a heritage plant in Sweden. The fragrance lingers.
- Multiple cropping systems of the world and the potential for increasing cropping intensity. Multiple cropping on 12% of total agricultural area, which could increase, but probably not as much as was thought.
- Impact and returns on investment of mungbean research and development in Myanmar. Four varieties coming out of international research created economic gains of USD 1.4 billion from 1980-2016. That’s a ROI of about 90, but it took 20 years to kick in.
- Are Traditional Food Crops Really ‘Future Smart Foods?’ A Sustainability Perspective. Well, they could be, but maybe we don’t have 20 years.

Biodiversity loss in experiments and in real life
A large body of research shows that biodiversity loss can reduce ecosystem functioning.
You don’t say. Several years ago we half-heartedly attempted to summarize the literature here a couple of times. We’ve sort of given up on that of late: there’s just too much of it. But there is a fundamental problem with this literature…
…much of the evidence for this relationship is drawn from biodiversity–ecosystem functioning experiments in which biodiversity loss is simulated by randomly assembling communities of varying species diversity, and ecosystem functions are measured.
Fear not, though, help is at hand. The two quotes above are from the abstract of a paper bearing the following title.
The results of biodiversity–ecosystem functioning experiments are realistic.
Phew.
