A comprehensive study spanning twenty-seven years has revealed that female birds face lower survival rates compared to their male counterparts. This trend has been observed in thirty-five distinct bird species throughout North America. The challenges posed by migration and reproduction seem to disproportionately affect females. Furthermore, genetic factors related to sex chromosomes may play a role in this issue.

A new fossil from Mongolia's Gobi Desert has reshaped mammalian evolutionary understanding. This 70-million-year-old Tamirkhan balcarceli fossil belonged to zhelestids, which were previously misunderstood. The complete skeleton shows zhelestids were not early placental mammals as once thought. Instead, they were part of the extinct zalambdalestoid lineage, which evolved similar teeth independently. This discovery alters interpretations of mammalian diversity during the Late Cretaceous period.

Large volcanic eruptions from the Pacific Ring of Fire influenced past climate. These eruptions correlate with major glacial advances and cold spells. Over eighty percent of glacial advances occurred near significant eruptions. Volcanic sulphur aerosols cause atmospheric cooling and reduce solar radiation. These eruptions may have intensified the 8.2 ka cold event.

Indigenous communities in Arunachal Pradesh are now earning livelihoods from a native spice. This wild Himalayan spice, known locally as Khagi, is helping over two hundred families. The community-led system for harvesting and marketing the spice supports forest patrols and biodiversity monitoring. This initiative provides a direct economic incentive for people to protect their forests and agricultural land. The project also contributes to the conservation of important transboundary wildlife habitats.
