Multi‐level functional responses for wildlife conservation: the case of threatened caribou in managed boreal forests

Abstract: Summary 1.The selection for particular habitat patches can vary as a function of local and regional levels of anthropogenic disturbance. Although such functional responses can better reveal habitat loss for species of precarious status faced with dwindling resources, they remain rarely used in conservation planning. We show that functional responses can occur at multiple levels, even as nested hierarchies, and that they can explain the plasticity in habitat selection observed in threatened forest-dwelling cari… Show more

“…However, when landscape composition differed greatly due to environmental or disturbance gradients, we found that models less accurately predicted habitat selection from one range to another. This is consistent with recent studies by Moreau et al (2012) and Johnson et al (2015), which determined that the landscape context is necessary to understand regional differences in habitat selection by caribou. In addition to the differences in spatial structure, we also observed differences in caribou behaviour across the ranges.…”

“…In addition to the differences in spatial structure, we also observed differences in caribou behaviour across the ranges. Spirit was the range with the highest disturbance (>20%); here caribou appeared to select recently disturbed areas, suggesting that caribou may have some plasticity in their tolerance of natural disturbance (Moreau et al 2012).…”

“…More recently, authors have advocated for multi-scale research and methods that emphasize or allow for the behavior of an organism to identify biologically relevant scales. Observing the variation in the behavior of an organism at multiple scales, and with different resources availability, provides opportunity for the data to inform the influence of a landscape feature [73][74][75]. Likewise, characterizing landscapes with a mix of variables drawn from both GM and PMM gives us the flexibility to accommodate the complexity of spatial ecology.…”

“…For example, Chan-McLeod and Moy (2007)observed that the red-legged frog (Rana aurora) movements were mainly 395 affected by the size of small forest patches (<1 ha) in landscapes where habitat removal was the result of low intensity disturbance processes, such as selective logging. On the other hand, Moreau et al (2012)showed that,in landscapes dominated by clear-cutting forestry practices, the movements of woodland caribou(Rangifertarandus caribou) were affected by habitat fragmentation within the home range (~ 500 ha). This suggests that when habitat is lost as a 400 consequences of high intensity processes, the movements of highly mobile species might be more affected by clustering of habitat at a coarse than at a finer resolution.…”
