Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 2254-2341, May 2026.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Generation cycles in experimental populations of a multivoltine insect

open access: yesJournal of Animal Ecology, Volume 95, Issue 5, Page 782-794, May 2026.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Large mammal recovery in the wake of human population decline

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Human depopulation, particularly in rural areas, has contributed to the recovery of some large mammal populations. While recovery is generally good news for conservation, it can also lead to human‐wildlife conflict. We present several avenues to maximize coexistence in the face of further rural depopulation in other places. Read the free Plain Language
