We examined the distribution of 80 species of breeding birds across 67 census plots from a variety of sources in the boreal forest of western and northern Canada to obtain information on bird habitat associations for forest management. The sites ranged from upland black spruce (Picea mariana) to riverine deciduous forests and wet, marshy bogs. Axis 1 of an ordination (detrended correspondence analysis) demonstrated a gradient in bird communities from dry to wet sites; axis 2 may have been a black spruce (nutrient poor) to mixed deciduous forest gradient (nutrient rich). Hierarchical classification (twinspan) identified five groups of sites according to their bird communities. Despite geographical variation in bird communities and possible geographical variation in habitat associations, sites were classified according to their forest types rather than regional affinities. Yellow-rumped warblers (Dendroica coronata) and dark-eyed juncos (Junco hyemalis) showed a pronounced gradient of increased abundance from deciduous to coniferous sites. White-throated sparrows (Zonotrichia albicollis) and alder flycatchers (Empidonax alnorum) showed a reverse gradient. In 22 sites of known-age aspen (Populus tremuloides) – mixedwood forests from central Saskatchewan, an ordination indicated a strong relationship between stand age (and thus the proportion of coniferous cover) and bird community structure. The highest combined densities of Neotropical migrants occurred in old forests, whereas short-distance migrants were most abundant in young forests. The highest abundance of upper-canopy gleaners was found in old forests, whereas ground foragers were most abundant in early successional forests. These findings have important implications for management of boreal forests.

Functional Evenness

ContextThe negative association between elevation and species richness is a well-recognized pattern in macro-ecology. ObjectivesThe aim of this study was to investigate changes in functional evenness of breeding bird communities along an elevation gradient in Europe. MethodsUsing the bird data from the EBCC Atlas of European Breeding Birds we estimated an index of functional evenness which can be assumed as a measure of the potential resilience of communities.ResultsOur findings confirm the existence of a negative association between elevation and bird species richness in all European eco regions. However, we also explored a novel aspect of this relationship, important for conservation: Our findings provide evidence at large spatial scale of a negative association between the functional evenness (potential community resilience) and elevation, independent of the eco region. We also found that the Natura2000 protected areas covers the territory most in need of protection, those characterized by bird communities with low potential resilience, in hilly and mountainous areas.ConclusionsThese results draw attention to European areas occupied by bird communities characterized by a potential lower capacity to respond to strong ecological changes, and, therefore, potentially more exposed to risks for conservation.

A new genus and species of ascomycetes, Catulus aquilonius, is described, illustrated, and tentatively assigned to the Mycosphaerellaceae. It grows as a parasite on stromata of Seuratia millardetii (Raciborski) Meeker and is characterized by two-celled, setulose ascospores.
