The combination of climate change and anthropogenic disturbance significantly impacts forest bird assemblages. Assessing the cumulative effects management on biodiversity ecosystem services, including carbon sequestration storage provisioning wood products is key to informing conservation decision making. Specifically, we projected changes in composition structure according various strategies under a changing using LANDIS-II for two case study areas Quebec (Canada): hemiboreal (Hereford Forest) boreal (Montmorency area. Then, assessed assemblage changes, as well sensitive at-risk species. As part an integrated assessment, evaluated best possible measures aimed at preserving avian diversity compared them with optimal options mitigation emissions atmosphere. Forest were lead significant assemblages both types through composition. We increase deciduous vegetation which favored species associated mixed stands detriment older, coniferous forests. Changes more pronounced Hereford than Montmorency Forest. In addition, Hereford’s mainly affected by change, while those impacted management. estimated that 25% 6% will be abundance (positive or negative) exceeding 25%.

Globally, the severity of wildfires is predicted to continue rise due climate change. Although fire an important natural disturbance, it unknown how changes in regime affect forest biodiversity, including bat community. Fire impacts insectivorous bats by changing foraging habitat, insect communities, and roosting opportunities. Our objective was determine effect extreme-severity wildfire on community Waterton Lakes National Park (WLNP), Alberta, Canadian Rocky Mountains. The Kenow burned 38% WLNP 2017. We hypothesized that had a positive all species study area, driven increased availability areas, coupled with local unburned areas provided refugia. examined activity using acoustic detectors record echolocation calls at thirteen sites for three years before after wildfire. used negative binomial generalized linear mixed models parameterized before-after control-impact design. results indicate response depended species. 40 kHz Myotis responded positively Compared pre-fire activity, (pre-fire mean 34.9 ± 5.4 SE passes/night versus 70.1 17.5 post-fire) decreased 132.0 27.6 123.0 22.7 post-fire), suggesting foraging, they moved from post-fire. big brown (Eptesicus fuscus) silver-haired (Lasionycteris noctivagans) group primarily negatively affected, fewer passes post-fire compared both 18.2 4.5 12.3 2.5 44.6 6.4 6.1 post-fire).

Additional monitoring would elucidate long-term effects provide insight into adaptability resilience change wildfires.
