The potential of seedbank digital information in plant conservation Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised d...

#consgen authority Fred Allendorf cries out in despair for American science in the Missoulian newspaper. It’s terrifying to watch this destruction unfold day by day. My heart goes out to my American colleagues and friends. Stay strong and fight.

Orchids have existed for 80 million years, but most of their diversity evolved in just the last 5 million! 🌸

The widely recognized extinction debt problem in community ecology depends on delayed genetic responses (genetic extinction debts/time lags) in the populations of that community. Therefore, genetic extinction debts at the population level deserve more attention /5

*Why it matters:*
Recognizing genetic extinction debts is crucial for effective conservation, both when monitoring genetic diversity and when taking actions to restore genetic diversity in populations /4

*Challenges in interpretation:*
Confounding factors, such as sampling strategies and marker choice, can obscure these debts and lead to misinterpretation. We propose a framework to guide better analytical approaches and to improve the interpretation of genetic extinction debts /3

*What are genetic extinction debts/time lags?*
These are delayed genetic consequences after environmental disturbance. Life-history traits such as long lifespan and vegetative propagation can favour time lags /2

Mind the lag: understanding genetic extinction debt for conservation The delay between disturbance events and genetic responses within populations is a common but surprisingly overlooked phenomenon in ecology and evolut…

There’s a time lag between an event and its impact on the genetic composition of a population ⏱️🧬

This cool new paper by @roberta-gargiulo.bsky.social explains why and how conservation strategies should account for this 🧪🌏

Genetic Bottlenecks Driven by Population Disconnection Abstract: Connectivity among populations plays a crucial role in maintaining genetic variation at a local scale, especially in small populations affected strongly by genetic drift. The negative con...

3/ An extinction debt also occurs when gene flow in a metapopulation drops below 1 MPG. This doesn't reflect a deviation from mutation-drift equilibrium, but from migration-drift equilibrium in the metapop. A drop in gene flow reduces the realized inbreeding Ne of the subpopulation.

2/ if allelic richness is smaller than expected from the observed He there is a pending extinction debt
The same principle applies to Tajima's D (haplotypes) or the Site Frequency Spectrum (SNPs).

New paper by @roberta-gargiulo.bsky.social on extinction debts and #popgen.
A bottleneck test is also a test for a genetic extinction debt 1/ at mutation-drift equilibrium Ne predicts allelic richness AR and gene diversity He and vice versa

Check out this new paper just out in Trends in Ecology & Evolution on better understanding genetic extinction debt for conservation.

Let´s form a community of conservation geneticists here - I started with some people I know, but there are likely to be many more... I can happily add them to this list
