Although much evidence exists showing organismal consequences from artificial light at night (ALAN), large knowledge gaps remain regarding ALAN affecting species interactions. Species interactions occur via shared spatio-temporal niches among species, which may be determined by natural levels. We review how is altering these through expanding twilight or full Moon conditions and constricting nocturnal as well creating patches of bright dark. literature a database to determine if dynamics. The indicates growing interest in interactions: 58% the studies we analysed have been published since 2020. Seventy-five 79 found altered Enhancements reductions were equally documented. Many revealed spatially, but few temporal alterations. There are biases ALAN-most investigated predator-prey with vertebrates predators invertebrates prey. Following this review, suggest avenues, such remote sensing animal tracking, that can guide future research on across spatial axes.

Predators can directly and indirectly alter the foraging behaviour of prey through direct predation risk predation, in doing so, initiate indirect effects that influence myriad species ecological processes. We describe how wolves trajectory forests by constraining distance beavers, a central place forager prolific ecosystem engineer, forage from water. Specifically, we demonstrate wait ambush kill beavers on longer feeding trails than would be expected based spatio-temporal availability beavers. This pattern is driven temporal dynamics beaver foraging: make more trips spend time land per trip extend farther As result, are vulnerable shorter ones. Wolf appears to selective evolutionary pressure propelled consumptive non-consumptive mechanisms constrain water forage, which turn limits area forest around wetlands, lakes rivers foraging. Thus, appear intricately linked boreal shaping behaviour, form natural disturbance alters successional states forests.

The assumption that activity and foraging are risky for prey underlies many predator–prey theories has led to the use of overlap as a proxy predation risk. However, simultaneous measures predator along with timing required test this have not been available. Here, we used accelerometry data on snowshoe hares ( Lepus americanus ) Canada lynx Lynx canadensis determine patterns predators match these precise predation. Surprisingly found kills were likely occur during day when inactive at night active. We also rates related chance daily weekly scales, whereas positively affected diel pattern their kill hares. Our findings suggest may always be good risk, highlight need examining link between spatio-temporal behaviour improve our understanding how behavioural interactions drive
