Summary1. There is great interest on the effects of habitat fragmentation, whereby habitat is lost and the spatial configuration of remaining habitat patches is altered, on individual breeding performance. However, we still lack consensus of how this important process affects reproductive success, and whether its effects are mainly due to reduced fecundity or nestling survival. 2. The main reason for this may be the way that habitat fragmentation has been previously modelled. Studies have treated habitat loss and altered spatial configuration as two independent processes instead of as one hierarchical and interdependent process, and therefore have not been able to consider the relative direct and indirect effects of habitat loss and altered spatial configuration. 3. We investigated how habitat (i.e. old forest) fragmentation, caused by intense forest harvesting at the territory and landscape scales, is associated with the number of fledged offspring of an area-sensitive passerine, the Eurasian treecreeper (Certhia familiaris). We used structural equation modelling (SEM) to examine the complex hierarchical associations between habitat loss and altered spatial configuration on the number of fledged offspring, by controlling for individual condition and weather conditions during incubation. 4. Against generally held expectations, treecreeper reproductive success did not show a significant association with habitat fragmentation measured at the territory scale. Instead, our analyses suggested that an increasing amount of habitat at the landscape scale caused a significant increase in nest predation rates, leading to reduced reproductive success. This effect operated directly on nest predation rates, instead of acting indirectly through altered spatial configuration. 5. Because habitat amount and configuration are inherently strongly collinear, particularly when multiple scales are considered, our study demonstrates the usefulness of a SEM approach for hierarchical partitioning of habitat amount vs. habitat configuration in landscape ecology that may have bearing on biological conclusions.

“…Throughout spring and summer, the probability of bear selection increased with decreasing distances from forest edges and rivers. The forest edge is habitat for Japanese macaque ( Macaca fuscata ; Enari and Suzuki , Mochizuki and Murakami ), sika deer ( Cervus nippon ; Agetsuma ), Asiatic black bears (Honda et al ), and other bears (Nielsen et al , Stewart et al ). With high temperatures and humidity of the monsoonal climate, shade‐intolerant liana species flourish, making forest edges denser and providing escape cover for bears in areas near human activity.…”

Season‐specific habitat restriction in Asiatic black bears, Japan

Understanding habitat selection by wildlife, particularly in the vicinity of areas dominated by humans, is often important in identifying causes of human-wildlife conflict. With recent increases in the number of Asiatic black bears (Ursus thibetanus) in areas near settlements in Japan, there have been more human-bear conflicts. Because of the seasonal nature of these conflicts, we hypothesized that a seasonspecific restriction in habitat may influence bears to select human-settled areas. To confirm this, we focused on the estimate of seasonal differences in distributions of potential bear habitat. We collected global positioning system data from 14 female and 15 male bears in a 1,023-km 2 range located in the central Alps of Japan. We employed resource selection functions to model season-specific habitat selection and quantified the spatial distribution of core habitat patches. Compared with other seasons, selected habitat of bears during summer was restricted to the narrow fringes of human-dominated lands. Selection for younger forests, edges, and lowland red pine (Pinus densiflora) forests supporting diverse food resources indicated that Asiatic black bears were seasonally dependent on early successional stages. In summer when human-bear conflicts peaked, bear avoidance of plantations and the selection for remnant small forest openings and lowland forest combined was the major cause affecting bear proximity to settlements. We recommend that wildlife managers work to restore food-producing habitat in dense, mature plantations to reduce negative interactions between humans and bears. Ó
