Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Reconstructing Early Human Subsistence in Near Oceania: New Insights From Matenkupkum and Matenbek

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT The colonization of New Ireland ~44–40,000 years ago represents the earliest evidence of human occupation in Near Oceania. Yet, the precise impacts of climatic changes on subsistence strategies during the Late Pleistocene, Last Glacial Maximum, and Holocene remain poorly understood.

More than proteins for empty stomachs: Wild meat in the BaTonga food system

open access: yesPeople and Nature, EarlyView.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.

Wild meat consumption in changing rural landscapes of Indonesian Borneo

open access: yesPeople and Nature, EarlyView.
Abstract Wild meat can play a crucial role in the food system of rural communities residing near tropical forests. Yet, socio‐ecological changes across tropical landscapes are impacting the patterns and sustainability of meat consumption. To understand the prevalence, frequency and drivers of wild meat, domestic meat and fish consumption in this ...

A broadly applicable method to characterize large DNA viruses and adenoviruses based on the DNA polymerase gene

open access: yesVirology Journal, 2006
Background Many viral pathogens are poorly characterized, are difficult to culture or reagents are lacking for confirmatory diagnoses. We have developed and tested a robust assay for detecting and characterizing large DNA viruses and adenoviruses.

Do cultural taboos regulate hunting in transitioning Indigenous communities? The case of the Idu Mishmi of Northeast India

open access: yesPeople and Nature, EarlyView.
Abstract There is rising recognition of resource‐use rights of Indigenous Peoples and Local Communities (IPLCs) within wildlife conservation. Historically, sociocultural institutions ensured wildlife sustainability in many IPLC areas. However, the future viability of such institutions is uncertain as IPLCs change in response to external pressures and ...
