Darwin's naturalization conundrum describes two seemingly contradictory hypotheses regarding whether alien species closely or distantly related to native species should be more likely to naturalize in regional floras. Both expectations have accumulated empirical support, and whether such apparent inconsistency can be reconciled at the global scale is unclear. Here, using 219,520 native and 9,531 naturalized alien plant species across 487 globally distributed regions, we found a latitudinal gradient in Darwin's naturalization conundrum. Naturalized alien plant species are more closely related to native species at higher latitudes than they are at lower latitudes, indicating a greater influence of preadaptation in harsher climates. Human landscape modification resulted in even steeper latitudinal clines by selecting aliens distantly related to natives in warmer and drier regions. Our results demonstrate that joint consideration of climatic and anthropogenic conditions is critical to reconciling Darwin's naturalization conundrum.

Elder abuse is a significant global issue, with health and social care professionals playing a crucial role in its detection and management. This cross-sectional study quantitatively surveyed 291 community care professionals in Singapore, recruited through convenience sampling. Participants completed a self-administered questionnaire assessing their capabilities (knowledge, attitudes, and confidence) and the barriers and enablers influencing their ability to address elder abuse.

Objectives: Addressing drug-resistant tuberculosis (DR-TB) is a priority of the tuberculosis (TB) programme. People with DR-TB frequently have worse outcomes and require more costly and complex management, compared with those with drug-sensitive TB (DS-TB). Our study examined the epidemiology of DR-TB in Sabah, Malaysia, a state with high TB burden.

The importance of naturalization-the establishment of species introduced into foreign places-to the early development of Darwin's theory of evolution deserves historical attention. Introduced and invasive European species presented Darwin with interpretive challenges during his service as naturalist on the HMS Beagle. Species naturalization and invasive species strained the geologist Charles Lyell's creationist view of the organic world, a view which Darwin adopted during the voyage of the Beagle but came to question afterward.
