Darkness in El Dorado: human genetics on trial

open access: yes, 2001
A recent book by a freelance journalist makes major accusations against genetic studies by J. V. Neel in the Amazon a generation ago. Contrary to these charges, there was no connection of Neel’s work with human experiments conducted by the Rochester ...

Emergence of Tigecycline‐Resistant Pseudomonas aeruginosa Harbouring tmexC6D6‐toprJ1b From Hospital Sewage in Japan

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This study isolated a Pseudomonas aeruginosa strain (KAM950) carrying the tmexCD‐toprJ gene cluster from hospital sewage in Japan. The strain exhibited reduced susceptibility to tigecycline and carbapenems, harboured chromosomal tmexC6D6‐toprJ1b and oprD disruption, and belonged to epidemic clone ST244, emphasising emerging multidrug resistance and the

Using miniaturized laboratory equipment and DNA barcoding to improve conservation genetics training and identify illegally traded species

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Illegal wildlife trade (IWT) is one of the largest global illegal activities, and it negatively affects biodiversity and sustainable development worldwide. DNA barcoding coupled with high‐throughput sequencing (i.e., metabarcoding) is useful in identifying taxa affected by IWT and has been used routinely for decades.

Genetic Diversity Impacts Climate‐Induced Species Range Shifts

open access: yesEcology Letters, Volume 29, Issue 4, April 2026.
Genetic diversity may buffer species against climate‐driven range contractions and facilitate expansions, but its role at a global scale remains unclear. Using 4673 range shift estimates for 1888 species, we show that higher genetic diversity reduces trailing edge contractions under rapid warming and accelerates leading edge expansions under moderate ...

Vascular plant diversity in Swedish road verges of high conservation value is threatened by the invasive alien herb Lupinus polyphyllus Lindley

open access: yesNordic Journal of Botany, Volume 2026, Issue 4, April 2026.
Road verges can be important habitats for vascular plant communities and the organisms that, in turn, depend on them. However, the plant diversity in Swedish road verges is threatened by the invasive perennial plant Lupinus polyphyllus Lindl. Therefore, this study aimed to investigate the effects of L.
