Museum specimens reveal the genomic consequences of long-term population decline in an insect pollinator

Victoria Mullin, Merchant Hana, Andres Arce, Will Nash et autres

Global insect pollinator populations are under threat, with reported declines attributed to increasing habitat loss, pesticide use, and disease. Tracking how genetic diversity has changed over time could reveal the rate and extent of these declines, and the adaptive capacity of affected …

The genome sequence of an ichneumonid wasp, Promethes sulcator (Gravenhorst, 1829) (Hymenoptera: Ichneumonidae)

Gavin R. Broad, Liam M Crowley, Inez Januszczak, Chris Fletcher et autres

(ichneumonid wasp; Arthropoda; Insecta; Hymenoptera; Ichneumonidae). The genome sequence has a total length of 278.74 megabases. Most of the assembly (99.67%) is scaffolded into 10 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 29.43 kilobases. This assembly …

Dogs were widely distributed across western Eurasia during the Palaeolithic

William A Marsh, Lachie Scarsbrook, Eren Yüncü, Lizzie Hodgson et autres

Abstract Archaeological evidence suggests that dogs diverged from wolves during the Palaeolithic, more than 15,000 years ago 1–7 . The earliest unequivocal genetic evidence, however, is associated with dog remains from Mesolithic archaeological contexts approximately 10,900 years ago 8,9 . Here we …

The genome sequence of the ichneumonid wasp Stenichneumon culpator (Schrank, 1802) (Hymenoptera: Ichneumonidae)

Gavin R. Broad, Ian Barnes, Chris Fletcher, Inez Januszczak et autres

We present a genome assembly from an individual female Stenichneumon culpator (ichneumonid wasp; Arthropoda; Insecta; Hymenoptera; Ichneumonidae). The genome sequence has a total length of 284.62 megabases. Most of the assembly (97.61%) is scaffolded into 14 chromosomal pseudomolecules. The mitochondrial genome has …

Ian Barnes, Chris Fletcher, Inez Januszczak, Gavin R. Broad et autres

(ichneumonid wasp; Arthropoda; Insecta; Hymenoptera; Ichneumonidae). The genome sequence has a total length of 299.91 megabases. Most of the assembly (81.88%) is scaffolded into 15 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 34.69 kilobases. This assembly …

Genetic evidence for invasive rat‐caused vegetation damage has implications for endemic Caribbean mammal management

Maria H. Zicos, Bryan Naqqi Manco, Junel Blaise, Rosalind J. Kennerley et autres

Abstract Invasive murid rodents have disrupted native biodiversity, including vegetation composition and structure, across island systems such as the Caribbean ecoregion. However, translocations of the Bahamian hutia ( Geocapromys ingrahami ), a threatened Caribbean rodent, have also prompted concerns about vegetation damage, …

Major excursions in sulfur isotopes linked to permafrost change in Eurasia during the last 50,000 years

Rhiannon E. Stevens, Hazel Reade, Kerry L. Sayle, Jennifer A. Tripp et autres

Abstract We identify a major sulfur isotope excursion in Eurasian faunal bone collagen from the last 50,000 years, here termed the Late Pleniglacial Sulfur Excursion. Our analysis suggests this is linked to changing permafrost conditions, presenting the utility of faunal collagen δ …

Sustainability insights from Late Pleistocene climate change and horse migration patterns

Yvette Running Horse Collin, Clément P. Bataille, Samantha N. Hershauer, Mila Hunska Tašunke Icu et autres

Climate affects habitat, food availability, and the movement and sustainability of all life. In this work, we apply Indigenous and Western scientific methods, including genomics and isotope profiling, on fossils from across Beringia to explore the effect of climate change on horses. …

A Million Years of Mammoth Mitogenome Evolution

Juan Camilo Chacón-Duque, Jessica Thomas, Wenxi Li, Marianne Dehasque et autres

The genomic study of specimens dating to the Early and Middle Pleistocene (EP and MP), a period spanning from 2.6 million years ago (Ma) to 126 thousand years ago (ka), has the potential to elucidate the evolutionary processes that shaped present-day biodiversity. …

Road to Extinction? Past and Present Population Structure and Genomic Diversity in the Koala

Binia De Cahsan, Marcela Sandoval‐Velasco, Michael V. Westbury, David A. Duchêne et autres

Koalas are arboreal herbivorous marsupials, endemic to Australia. During the late 1800s and early 1900s, the number of koalas declined dramatically due to hunting for their furs. In addition, anthropogenic activities have further decimated their available habitat, and decreased population numbers. Here, …
