“…Like Brannon (2000), Carey and Johnson (1995), and Lee (1995), we found that the importance of CWD varied among shrew species. Specifically, C. parva was the most sensitive species in this assemblage to the removal of logs.…”

“…This likely reflects a decrease in reproduction at plots from which CWD was removed, though the small number of pregnant shrews in our sample (n ¼ 8) prevented a direct test of this hypothesis. Lee (1995) found reproduction of S. monticolus and S. trowbridgii to decrease after removal of dead wood. Coarse woody debris is often associated with sites, such as dens and roosts, used for reproduction by wild rodents (McCay, 2000) and bats (Menzel et al, 2001) in similar habitats.…”

“…However, S. vagrans was captured more frequently in Douglasfir forests from which dead wood was removed than forests from which dead wood was not removed (Lee, 1995). Lee (1995) found that reproduction of S. monticolus and S. trowbridgii declined at plots from which CWD was removed, suggesting that demographic responses to the removal of CWD may not be limited to changes in abundance.…”

“…However, certain segregation of habitat niches is usually observed. It relied on selection of places differing with regard to the following microhabitat factors: density and type of plant cover, distance to water, soil wetness or water level, soil type or richness, litter layer, and quantity of woody debris (Spencer and Pettus 1966, Brown 1967, Hawes 1977, Wrigley et al 1979, Terry 1981, Neet and Hausser 1990, Sheftel 1994, Shvarts and Demin 1994, Dickman 1995, Lee 1995, Castien and Gosalbez 1999. In some cases separation of habitat optima or mutual habitat exclusion has been observed (Hawes 1977, Neet and Hausser 1990, Sheftel 1994.…”

Habitat preferences were studied in a shrew community of two semiaquatic species, Neomys anomalus Cabrera, 1907 and N. fodiens (Pennant, 1771), and two terrestrial species, Sorex araneus Linnaeus, 1758 and S. minutus Linnaeus, 1766, in a study area (5600 m ) alongside a small stream in Białowieża Forest (E Poland). Preferences were estimated by relating frequency of captures with macro-and microhabitat characteristics of trapping points. Distance to the stream and ground wetness appeared to be more important than macrohabitat and plant cover in separation of habitat niches. N. fodiens was trapped at places significantly wetter and closer to the stream than the three other species, N. anomalus was captured at places wetter and closer to the stream than S. araneus and S. minutus was trapped closer to the stream than S. araneus. Habitat preferences of these species reflected vertical segregation in their foraging. The interspecific overlaps in habitat preferences were lowest between N. fodiens and the two Sorex species and highest between N. anomalus and S. araneus and between the two Sorex species. An inverse relationship between the breadths of the trophic and habitat niches of the shrews appeared: the greatest trophic specialist S. minutus had the broadest habitat niche, whereas the greatest trophic generalist N. fodiens had the narrowest habitat niche. High interspecific overlaps in habitat preferences and little overlaps in spatial distribution suggest that the separation of ecological niches of these four species in the study site reflects other mechanisms in addition to habitat preferences.

Downed wood removal effects on survival and site fidelity of woodrats in a California oak woodland

Owing to the increasing intensity and frequency of wildfires in the western United States, the removal of woody debris (downed dead wood and snags) from fire‐prone landscapes is being evaluated for wildfire mitigation. Consequently, the study of the ecological value of coarse woody debris to sustain dependent species has become of foremost importance. From 2004–2009, we used a before‐after control‐impact (BACI) study design to assess the effects of downed wood removal on a population of big‐eared woodrats (Neotoma macrotis) in an oak woodland (Quercus spp.) in coastal‐central California, USA. Using Pollock's robust design mark‐recapture analyses (with 12 primary capture occasions represented by trapping each spring and fall, and secondary occasions composed of 3 trap nights), we estimated survival and emigration rates. Further, applying mixed‐effects models, we evaluated the effects of 7 habitat attributes on woodrat abundance and reproduction. Following the experimental removal of downed wood from the 11 randomly selected treatment plots, woodrat survival was higher (P = 0.013), and emigration was lower (P = 0.007) among 11 control plots on which downed wood was retained. Woodrat abundance within plots was best predicted by stem density, demonstrating positive demographic associations with habitat complexity. Plot‐level reproductive success (i.e., the presence of juveniles within a plot during spring) was more likely with increasing snag density. These findings indicate that snags and downed dead wood are key components of high‐quality habitat for big‐eared woodrats. Management of woody debris to mitigate wildfire risk should consider the ecological value of this habitat attribute for big‐eared woodrats and other dependent species.
