- Drought-exposure history increases complementarity between plant species in response to a subsequent drought. Repeated stress makes plant species get along better, sustaining diversity. If only it worked so well with people…
- A quantitative synthesis of soil microbial effects on plant species coexistence. Meta-analysis shows soil microbes work against plant species getting along better.
- Does crop diversification lead to climate-related resilience? Improving the theory through insights on practice. Crops getting along well together is pretty well linked to better livelihoods, but less strongly to increased resilience.
- Local Adaptation: Causal Agents of Selection and Adaptive Trait Divergence. You need to do reciprocal transplant experiments really well to find out where plants are best adapted and why. Probably means taking microbes into account.
- Genetic variance in fitness indicates rapid contemporary adaptive evolution in wild animals. Natural selection can be quicker than climate change. I hope they did the reciprocal transplant experiments really well.
- Global genetic diversity status and trends: towards a suite of Essential Biodiversity Variables (EBVs) for genetic composition. Genetic diversity, Genetic differentiation, Inbreeding, and Effective Population Size (Ne). Who needs reciprocal transplant experiments?
- On the feasibility of estimating contemporary effective population size (Ne) for genetic conservation and monitoring of forest trees. Ouch.
- Selecting species and populations for monitoring of genetic diversity. All of them, right?

- Exploring Convivial Conservation in Theory and Practice: Possibilities and Challenges for a Transformative Approach to Biodiversity Conservation. Conservation should be integrative, democratic and redistributive. Hard row to hoe.
- Emerging signals of declining forest resilience under climate change. Convivially or not, better conserve forests quickly.
- Adapting traditional industries to national park management: A conceptual framework and insights from two Chinese cases. Integrative and redistributive, but I’m not sure how democratic.
- Near- to long-term measures to stabilize global wheat supplies and food security. There’s a bunch of stuff that we can do in the short term, but in the end we’re going to need diverse, gender-equitable agro-ecosystems which are properly supported by investment in research. Sort of integrative, democratic and redistributive then, perhaps?
- From food price crisis to an equitable food system. Looks like the food system needs to be as convivial as conservation. If not more so.
- Trade and dietary preferences can determine micronutrient security in the United Kingdom. Going to be difficult to take back control of micronutrient security.
- Turning promise into practice: Crop biotechnology for increasing genetic diversity and climate resilience. Maybe biotech needs to be more convivial too.
- A conceptual framework for understanding the environmental impacts of ultra-processed foods and implications for sustainable food systems. Nothing convivial about ultra-processed foods, alas.
- Why food insecurity persists in sub-Saharan Africa: A review of existing evidence. Exports, basically. Looks like exports are really not very convivial.
- Crops in crises: Shocks shape smallholders’ diversification in rural Ethiopia. Farmers need continual access to both the informal and formal seed systems to mitigate risk, but poor farmers need more money to do so. Maybe link them up to export markets? No, wait…
- Traditional Agriculture and Food Sovereignty: Quilombola Knowledge and Management of Food Crops. Lots of conviviality, but not enough to fully mitigate risk.
- The role of international cooperative initiatives in financing biodiversity. Partnerships between state and a variety of non-state actors may just be an opportunity for more convivial conservation and food systems. But then I would say that.
Returning to recollecting
We’ve referred to Project Baseline here a couple of times, but always somewhat desultorily. But I think that needs to end now that the project hit the big time with a shoutout in Gizmodo.
Based at the University of Minnesota Duluth, Project Baseline re-collects seeds multiple times from the same sites to see how populations change genetically and phenotypically.
In the Resurrection Approach, dormant ancestors are reared in a common garden with contemporary descendants. The Project Baseline collections are designed to maintain the genetic structure of populations to facilitate researchers utilizing the resurrection approach. Seeds are collected and stored separately by maternal plant from up to 200 individuals per population. After collection, seeds were cleaned and [conserved] at the NLGRP.
That phrase “reared in a common garden” is doing a lot of work, as the flowchart in a 2017 paper describing the Resurrection Approach shows.
Turns out we blogged about this too, almost 15 years ago, though there didn’t seem to be a Project Baseline yet at the time. I was maybe a bit hard on that press release, but more because of the misconceptions about genebanks that it revealed rather than the concept of re-collecting from the same site or population to monitor genetic change. That of course is extremely valuable, as our recent review of genetic erosion showed.

- Long-term evidence for ecological intensification as a pathway to sustainable agriculture. Meta-analysis of 30 long-term experiments from Europe and Africa comprising 25,565 data points shows that increasing crop diversity and adding fertility crops and organic matter are as good for the yield of staple crops as N fertilization, but don’t add much if you already have the latter, and vice versa.
- Revisiting the adequacy of the economic policy narrative underpinning the Green Revolution. If only the Green Revolutionaries had know the above, eh? Anyway, remember institutions, people.
- Agroecological practices increase farmers’ well-being in an agricultural growth corridor in Tanzania. Higher awareness of the benefits of nature plus more engagement with extension services mean more adoption of agroecological practices means farmers are better off. Green Revolutionaries unavailable for comment. Institutions rejoice.
- Intangible links between household livelihoods and food security in Solomon Islands: implications for rural development. Diversifying livelihoods isn’t always associated with better food security.
- Access to and Utilization of Wild Species for Food and Nutrition Security in Teso and Acholi Sub-regions of Uganda. Wait, does the above mean that decreasing access to wild foods may not necessarily matter? Why does this stuff have to be so hard?
- Climate Change and Seed System Interventions Impact on Food Security and Incomes in East Africa. More crop diversity on farms “helps farmers cope with climate change and increases productivity, food availability, incomes and food security.” Not so hard after all.
- Welfare impacts of improved groundnut varieties adoption and food security implications in the semi-arid areas of West Africa. Adopting new peanut varieties is good for farmers. Wait, so the opposite of more crop diversity? Why does this stuff have to be so hard?
- Situating Plant Genetic Resource in the K-12 Curriculum: A Critical Review. Maybe we should all go back to school.
Nibbles: Livestock genebank, Purple grain, Traditional Hawaiian farming
- Call to set up a sheep genebank in Australia. Kinda surprised there isn’t one already, frankly.
- Bringing back purple wheat in the US. Spoiler alert: genebanks were involved.
- Going back to “organized chaos” in Hawaiian farming. There’s probably room for genebanks too, though.
