Marine monitoring efforts are increasingly supported by opportunistic shipboard surveys. However, opportunistic survey methods often require adaptation to suit the vessel and the operations being conducted onboard. Whilst best-practice techniques for surveying marine wildlife on vessels of opportunity are yet to be established, testing and development of alternative methods can provide means for capturing ecological information in otherwise under-surveyed areas.

- The study investigates hybridization among baboons to enhance our understanding of primate evolution, focusing on olive and yellow baboon species at the Southwest National Primate Research Center.
- Researchers used full genome data from 881 baboons to analyze genetic ancestry and improve the quality of genetic markers, discovering historical admixture in some supposedly purebred specimens.
- The findings included the creation of updated genetic maps and a set of 1,747 ancestry informative markers, which show strong agreement in global ancestry estimation but revealed phase switch errors influenced by the methods used.
Article Synopsis
- Around 42,000 years ago, modern humans arrived in Western Europe, impacting Neanderthal populations and giving rise to new cultural complexes like the Châtelperronian, which spans regions from northern Spain to Paris.
- The Grotte du Renne site is significant for understanding the identities of those who created this culture, providing Neanderthal remains and a neonate ilium (AR-63) that required detailed analysis of its morphology.
- Our analysis using geometric morphometrics indicated that the neonate's ilium differs from Neanderthals, suggesting it belongs to an early modern human lineage, and we discuss various theories regarding its coexistence with Neanderthal remains.
Detection is essential to studying and monitoring wild animals; however, detection is challenging for small endotherms that are nocturnal or best detected at night. Techniques such as trapping or spotlighting disturb focal species, and the effectiveness of spotlighting can be limited for cryptic species, resulting in low detection rates that hinder our ability to monitor and study some endotherms at night. Thermal scanners detect infrared wavelengths not otherwise visible to humans.

- Researchers analyzed genetic data from 13 Neanderthals found in two caves in southern Siberia to better understand their social organization.
- The study revealed family relationships among some individuals and suggested they were part of a small community, indicated by high levels of genetic similarity.
- Findings show that female Neanderthals likely migrated between communities, as evidenced by the lower diversity in Y-chromosome data compared to mitochondrial data.
