A new collaboration📜paper just published in Genome Research. We observed that individuals of the Western African cichlid Benitochromis nigrodorsalis are capable of reproduction even when isolated for years. Now, by analyzing genome-wide SNPs and measuring maternal heterozygosity, we provide clear evidence for facultative selfing in this cichlid species, a potentially adaptive strategy when mating partners are absent. https://doi.org/10.1101/gr.277368.122 #genetics#genomics#evolution@academicchatter
Sex and the epigenome: Fully funded PhD to investigate how reproductive mode influences epigenetic inheritance. Based in Nelson, New Zealand. Position open until filled.
"We present 14 new ancient mitogenome sequences from pre-Phoenician (~1800 BCE) and Phoenician (~700–400 BCE) samples from Lebanon (n = 4) and Sardinia (n = 10) and compare these with 87 new complete mitogenomes from modern Lebanese and 21 recently published pre-Phoenician ancient mitogenomes from Sardinia to investigate the population dynamics of the Phoenician (Punic) site of Monte Sirai, in southern Sardinia."
"In the context of European populations, and particularly in Iberia, this haplogroup stands out for its high frequency and its demographic history. Current evidence indicates that the diffusion of this haplogroup is related to the population movements that mark the cultural Bronze Age transition, making it remarkably interesting for population geneticists."
"Here, we survey the genomic evidence for human dispersals during the Holocene in various geographic regions of the world, focusing on proposed expansions linked to agriculture."
🇮🇪 "The Neolithic and Bronze Age transitions were profound cultural shifts catalyzed in parts of Europe by migrations, first of early farmers from the Near East and then Bronze Age herders from the Pontic Steppe. However, a decades-long, unresolved controversy is whether population change or cultural adoption occurred at the Atlantic edge, within the British Isles."
