The Christmas Island shrew (Crocidura trichura), once abundant on Christmas Island, has been declared extinct due to the introduction of invasive species and habitat destruction. Despite brief rediscoveries in 1958 and 1984, the species could not be saved, highlighting the fragility of ecosystems and the impact of human activities on native wildlife. Its extinction marks the 39th mammal species lost in Australia since colonization, serving as a reminder of the unseen losses in biodiversity.

Scientists have discovered Iceland's first mosquitoes, specifically the Culiseta annulata species, marking a significant shift in the country's ecosystem previously protected by harsh winters. The discovery highlights concerns about climate change, as rising temperatures may be facilitating the establishment of these insects in areas where they were once absent. Further monitoring will be necessary to determine if the species can survive the winter in Iceland.

The article discusses the intriguing case of Colin Wyatt, an English collector who stole thousands of butterfly specimens from Australian museums. His actions have left scientists, like Dr. Michael Braby, grappling with the implications of these thefts on biodiversity research and conservation efforts, particularly as one notable specimen was discovered to be a painted fake rather than a genuine butterfly.
