- Why Seed Physiology Is Important for Genebanking. Well, don’t you want to know why a seed lot is showing no or low germination after 30 years in permafrost? Or, alternatively, how long another one will continue to show good germination? Thought so.
- Habitat management alternatives for conservation forests in the temperate zone: Review, synthesis, and implications. 4 intervention alternatives: minimal, traditional, non-traditional and species-based. But we need long-term studies to really know what works best. Presumably longer than 30 years. This is an old paper, but it came up again because of this very thorough Twitter thread.

I guess people are mainly sitting at home making videos during the lockdown. Here are two on Svalbard which dropped within a couple of days of each other, presumably in time for the International Day for Biodiversity. Which is today, isn’t it?
And you might as well complement them with this nice article from Simran Sethi.
The EU gets a new biodiversity strategy
The decline of genetic diversity must also be reversed, including by facilitating the use of traditional varieties of crops and breeds. This would also bring health benefits through more varied and nutritious diets. The Commission is considering the revision of marketing rules for traditional crop varieties in order to contribute to their conservation and sustainable use. The Commission will also take measures to facilitate the registration of seed varieties, including for organic farming, and to ensure easier market access for traditional and locally adapted varieties.
That’s from the EU’s new biodiversity policy. Promising. But I don’t see anything in there about ex situ conservation to back up this conservation-through-use approach, welcome as it is.
