Check out our latest preprint: the relevance of pedigrees in the conservation genomics era TLDR: it’s not either/or when it comes to #pedigrees & #genomics. Having both helps researchers address more conservation questions than one data set alone. 🧵 1/10
Conservation #genetics 🧬 has developed a substantive toolbox 🔧 to inform species management. While much discussion has been dedicated towards genomic advances, there remains one long-standing tool in #ConGen that is often overlooked: the pedigree. 2/10
Pedigrees have been used to understand and manage diversity in threatened populations for decades. But, caveats like assumed founder relatedness, missing data, and errors can make them tricky to use. See Forsdick et al ( for more. 3/10
Molecular data can address these caveats, and genomic data can provide similar estimates of relatedness to robust pedigrees, as explored in Galla et al. 2020 ( 4/10
But now that we can estimate relatedness with genomic data, some have asked whether pedigree data is worthwhile in the conservation genomics era. Here, we say YES. 5/10
In our paper (, we describe how 🧬 data can reconstruct, complete, & validate pedigrees. Pedigrees can help with 🧬 study design & provide important life history, ecological & demographic context for quantitative genetic and genomic analyses. 6/10
Through perspectives from our practitioner & Indigenous coauthors conserving critically #endangered species in #Aotearoa NZ 🇳🇿, we contend that the act of building & sharing pedigrees can bridge gaps between researchers, practitioners, Indigenous Peoples & local communities. 7/10

We are excited to share our pub in #EvolutionaryApplications comparing relatedness estimates for pairing recommendations in critically #endangered #birds from #Aotearoa #NZ 🇳🇿. See this #SciComm 🧵 for more! #Conservation #Genomics #ConGen #ConSERTeam 1/13
Around the 🌏, #conservation breeding programmes strategically pair the least related individuals to enhance recovery. This is like #Tinder for threatened species, only more information goes into pairing than swiping ⬅️ or ➡️. See my #3MT for more! 2/13

It’s important to get the relatedness value right for pairing, because mating between close relatives can result in negative fitness consequences, like ⬇️ hatching success 🐣(see 3/13

Exciting #ConSERTeam news! Our paper demonstrating the utility of closely-related reference genomes 🧬 for #conservation (Galla & Forsdick et al. 2019 @sgalla32 @NatForsdick @testeeves was published in @Genes_MDPI @MDPIOpenAccess. #ConGen 1/13
No longer just a promise (, the #ConservationGenomics revolution is here: #genomics is adding awesome tools to the #conservation tool box to inform the management of some of the world’s most threatened species. 2/13
One such tool is a reference #genome. Think of it as the picture of a completed puzzle on a puzzle box. Having a picture means genomic reads (puzzle pieces 🧩) can be placed correctly, allowing effective ID of SNPs (single nucleotide polymorphisms). 3/13
