“…It was proven that the forests with complex composition and floristic richness have a high diversity of birds' communities (Easton, Martin, 2002;Poulsen, 2002;Westphal et al, 2003;Wilson et al, 2006). Results of other studies showed that change in the number of bird species and the formation of guilds of birds depends on the forest type and vertical hetero-geneity: the number of birds decreased with decreasing vertical heterogeneity (Wen et al, 2002).…”

Blinkova O., Shupova T.: Bird communities and vegetation composition in the urban forest ecosystem: correlations and comparisons of diversity indices. Ekológia (Bratislava), Vol. 36, No. 4, p. 366-387, 2017.Assessment of relationships and diversity indices between bird's communities and composition of the forest ecosystem is an important subject of synecological research to identify the intensity of human impact on the flora and fauna. Urban recreation is one of the major causes of violation of the structural and functional integrity of the forest ecosystem. Studies of avian complex and phytocoenosis have focused on the impact of urban recreation on the compositions of tree, shrub and herbaceous layers and species, trophic and ecological compositions of breeding-birds and feeding-birds communities. This paper compares the measurement of the diversity of bird communities and forestry vegetation (diversity indices, dominance indices, distribution uniformity indices) of intensive, medium, moderate and weak stages of recreational transformation of biotope. The stands formed Quercus robur L., Carpinus betulus L., Acer platanoides L., Tilia cordata L. The floristic list comprised 78 grass species. A total number of 43 species of avifauna including 37 breeding species are observed during the study. There were significant correlations between vertical heterogeneity of tree distribution and abundance, species richness and nesting density of birds. The interrelationship between species diversity of birds and floristic richness was also confirmed.

“…In the MLR, 85-90% of the native vegetation has been cleared since European settlement and the distribution of the remaining vegetation is patchy and unrepresentative of historical conditions (Westphal et al 2003). As a consequence of loss of habitat, the MLR has lost, and is expected to continue to lose, a significant proportion of its avifauna (Ford and Howe 1980;Ford et al 2001;Possingham and Field 2001).…”

Approximately 90% of the original woodlands of the Mount Lofty Ranges of South Australia has been cleared, modified or fragmented, most severely in the last 60 years, and affecting the avifauna dependent on native vegetation. This study identifies which woodland-dependent species are still declining in two different habitats, Pink Gum-Blue Gum woodland and Stringybark woodland. We analyse the Mount Lofty Ranges Woodland Bird Long-Term Monitoring Dataset for 1999-2007, to look for changes in abundance of 59 species. We use logistic regression of prevalence on lists in a Bayesian framework, and List Length Analysis to control for variation in detectability. Compared with Reporting Rate Analysis, a more traditional approach, List Length Analysis provides tighter confidence intervals by accounting for changing detectability. Several common species were declining significantly. Increasers were generally large-bodied generalists. Many birds have already disappeared from this modified and naturally isolated woodland island, and our results suggest that more specialist insectivores are likely to follow. The Mount Lofty Ranges can be regarded as a 'canary landscape' for temperate woodlands elsewhere in Australiawithout immediate action their bird communities are likely to follow the trajectory of the Mount Lofty Ranges avifauna. Alternatively, with extensive habitat restoration and management, we could avoid paying the extinction debt.

“…A key challenge for better understanding distributional patterns of species with active habitat selection is to identify the cues that the individuals use to choose their breeding sites. The individuals may assess sites directly based on their environmental characteristics, such as availability of food, refuge from predators and a safe environment for nesting (Westphal et al 2003). As an alternative, the individuals may also use social information, the presence of con-and heterospecifics indicating that the site is likely to be suitable for breeding (e.g.…”

Testing the heterospecific attraction hypothesis with time-series data on species co-occurrence

et al. 2010

The distributional patterns of actively moving animals are influenced by the cues that the individuals use for choosing sites into which they settle. Individuals may gather information about habitat quality using two types of strategies, either directly assessing the relevant environmental factors, or using the presence of conspecifics or heterospecifics as an indirect measure of habitat quality. We examined patterns of heterospecific attraction with observational time-series data on a community of seven waterbird species breeding in artificial irrigation ponds. We fitted to the data a multivariate logistic regression model, which attributes the presence -absence of each species to a set of environmental and spatial covariates, to the presence of con-and heterospecifics in the previous year and to the presence of heterospecifics in the same year. All species showed a clear tendency to continue breeding in the same sites where they were observed in the previous year. Additionally, the presence of heterospecifics, both in the previous year and in the same year, generally increased the probability that the focal species was found breeding on a given pond. Our data thus give support for the heterospecific attraction hypothesis, though causal inference should be confirmed with manipulative experiments.
