Zhalong National Nature Reserve (Zhalong) is an important habitat of avian, especial for cranes and waterfowls. For grasping the relation between avian ecological group and habitat types and scientific management for resource, we used line transects to survey bird population and distribution during November-December from 2005-2009 at Zhalong, and used cluster analysis and Chi-Square tests to analyze data. We recorded 23 bird species of 15 families and 7 orders during the wintering period, including Anseriformes, Columbiformes, Falconiformes, Galliformes, Gruiformes, Passeriformes, Strigiformes. Geographic region and dominant vegetation were the main influence factors of wintering avian distribution at Zhalong. Different ecological groups preferred different habitat types (p<0.01). Reed marsh were strong preferred, next were farmland and open forest. Passeres preferred reed marsh, open forest and farmland; Raptatores preferred open forest and reed marsh; Terrestores and Grallatores all preferred reed marsh and farmland. Different avian ecological groups occupied specific habitats types and we recorded some overlaps in bird distribution.

The Relationship

The analysis of macromycetes against the background of forest communities is presented in the paper. The relationship between the mycoflora and the exploited habitat - type of phylocoenosis, stand composition, type of substrate, humidity - has been determined referring to ecological groups of fungi. Communities with considerable proportion of fir-tree in stand were particularly taken into consideration.

Abstract This research was carried out in Kyiv Polissya geobotanical province, in one of most common woods type - fresh and wet sudubravas. Its purpose is to determine ornithocenosis structure in different age groups of this type of forest. To achieve that, forest bird species lists were composed, their population density and that of ecological groups of birds were calculated. In the course of the research in the breeding periods of 2013-2014, two-time surveys were carried out on 12 survey routes of total length 33 km. For further analysis, forests were divided into age groups: 0-20 years, 20-40 years, 40-60 years, 60-80 years, 80-100 years and forests over 100 years. Altogether 53 bird species were found. Species lists were poorest in the forests of 0-20 years (18 species), and richest in the forests over 100 years (39 species). Minimal population density was 473 individuals per square kilometer in the youngest forest age group of 0-20 years, maximal - 2155 individuals per square kilometer in pine forests aged over 100 years. Analysis of different population densities of ecological groups reveals steadily growing numbers of hollow-nesting birds and tree-nesting birds in accordance with aging of the forests. In older forests hollow-nesting birds constitute an absolute majority. Population density of another ecological group shows no such direct tendency.

Neotropical wetlands comprise contrasting habitats with highly diverse avifauna, including herbivores, insectivores and carnivores, of both terrestrial and aquatic species. Therefore, comparisons between wetland bird assemblages based only on species identity may disregard turnover within ecological groups, and eclipse important variations between habitat types. We studied bird assemblages from mangrove and estuary habitat types from a coastal lagoon system in Oaxaca, Mexico. For this, we used 640 point counts to obtain data on bird species using those habitats between October 2009 and May 2012. We ascertained guild structure by classifying 139 species in a scalar hierarchy of two-levels: 17 key-resource guilds nested within seven trophic guilds. To evaluate variation in guild structure between habitat types, we contrasted richness and diversity across trophic guilds and tested for variation in abundance within key-resource guilds. We exposed a tendency of greater diversity within terrestrial guilds in mangrove and within aquatic guilds at the estuary. However, these differences were compensatory and neither richness nor diversity varied between habitat types in comparisons across the sets of trophic guilds. Parallel analyses at two hierarchical levels supported the theoretical prediction of greater change at lower levels. Herpetofauna, wood invertebrates, aquatic invertebrates and seeds emerged as dietary components that may explain the distribution of abundance in key-resource guilds. Although the guilds from mangrove and estuary produced comparable sets of richness and diversity values, the actual identity of guilds with high values varied between habitats. On the other hand, species abundance comparisons within guilds pinpointed specific associations with habitat types and this method represents a suitable strategy for identifying habitat preferences in complex wetland bird assemblages.

Around the 2007 yearly cycle, we carried out a transect in a Mediterranean sandy beach (central Italy), a structurally oversimplified ecosystem, elaborating the data in six bimonthly periods and in three longitudinal habitat types. We observed 25 bird species. Assemblages appear heterogeneous at taxonomic-, phenological- and ecological-level. Also normalizing (Margalef index), in winter the beach hosted the richest assemblage, in summer-autumn the lowest. The inner dunal area appears the richest habitat type. Here, the presence of vegetation presumably permits the occurrence of a large availability of different trophic resources for different species. Beaches represent patchy ecosystems with a different availability of resources in space and time that host heterogeneous bird assemblages, different in their ecology and phenology around a yearly cycle.

The present study aimed to investigate the structure, composition and diversity of the over-wintering aquatic bird community of Poyang Lake, including Poyang Lake National Nature Reserve (PNNR), Nanji National Nature Reserve (NNNR) and Duchang Provincial Nature Reserve (DPNR), China. After the preliminary survey, birds surveyed from vantage points at each study site between the years 2016 and 2020 in the winter season. A total of 58 bird species belonging to nine orders and 13 families were observed. The study showed variation in effective species numbers (Species richness, Shannon’s diversity and Simpson’s diversity) among the three study sites and the survey years. Nanji National Nature Reserve had the highest avian diversity, whereas Duchang Provincial Nature Reserve had the lowest. Globally threatened bird species, Siberian Crane (critically endangered), Oriental Stork (endangered), found in our study sites. However, the current management practices of the nature reserve and conservation of this globally threatened bird species are inadequate, especially of Duchang Provincial Nature Reserve. Therefore, for long term conservation of birds in these areas, it needs continuing intentional improvement of the sites and awareness creation to the local community.

AbstractThe structure of a breeding bird assemblage of a primeval alder swamp in the Šúr National Nature Reserve (the Danube Basin) was studied in the period 1992–1995. A 16 ha forest interior study plot was established for bird censusing. Population abundances were estimated by a combined version of the mapping method from the end of March to the beginning of July. Altogether, 42 breeders were recorded and the mean total density of species total across years was 125.15 ± 12.73 pairs/10 ha (CV = 10.17%). Two species were eudominant (≥ 10%): Sturnus vulgaris and Anas platyrhynchos, and six species were dominant (5% ≤ 10% <): Ficedula albicollis, Fringilla coelebs, Phylloscopus collybita, Parus major, Sylvia atricapilla, Erithacus rubecula. The Shannon diversity index (H′) varied between 3.98–4.10 bites. The evenness index (J′) reached values between 0.79–0.81. Expected species diversity in a random sample of 100 pairs calculated by rarefaction [E (S 100 pairs)] was 21.35 ± 0.92 species derived as a mean value from the years 1992–1995. The mean rarefaction estimate on the area [E (S 10 ha)] was 22.75 ± 1.58 species. Bird species richness and diversity were significantly higher in the study plot in comparison to the mean value of European wet alder forests. These results are comparable with the values of structural assemblage parameters of the primeval stands dominated by alder within the Białowieża National Park, Poland.

Abstract Urbanisation is a leading cause of biodiversity loss and habitat fragmentation internationally, and the conservation of representative native assemblages is a challenge confronting environmental managers in expanding urban landscapes. This study investigates the bird assemblages occurring in a rapidly growing regional centre, Ballarat, southeastern Australia. It aims to examine the relationships between urbanisation and bird communities in a regional city by investigating the differences in bird assemblage composition related to the type of vegetation (native or exotic) in urban streetscapes. Bird surveys were completed across four broad habitat types: remnant vegetation, exotic streetscapes, native streetscapes and newly developed streetscapes. Each habitat type had three 1 ha replicate sites. Results show that remnant vegetation fringing residential areas and native streetscapes supported around 60% more native bird species than exotic and newly developed streetscapes. Avian species composition was significantly different between broad habitat types, with remnant vegetation and native streetscapes maintaining representative native bird assemblages, but exotic streetscapes and newly developed streetscapes were dominated by introduced birds. Our results show that, for representative native bird assemblages to be maintained in urban areas, the maintenance of remnant and native vegetation is essential.

Abstract Patterns in bee assemblages consisting of 52 core (most abundant) species in farmland in the Wielkopolska region of W Poland were analysed. The entomological material was assessed during earlier research in 1978-1993 from 18 plots in three habitat types: shelterbelts, roadsides and forest patches. At the scale of the refuge habitat size analysed here, an increase in area only slightly enhanced bee species richness. The bee assemblage structures of roadsides and forest patches differ significantly, but their indicator species do not form any well-defined ecological groups. In non-linear forest patches, the bee community structure was more homogeneous than on roadsides. These two habitat types differed significantly in their species composition. Nine significant indicator species were found, but they did not share any ecological characteristics. Three factors were found to affect significantly the responses of individual bee species in the agricultural landscape: the degree of isolation of the refuge habitat, the edge ratio, and roadsides as a refuge habitat type. A large part of the regional diversity is due to the heterogeneity of habitats within the landscape. Habitat area has little influence on the diversity of wild bees, at least within the size range analysed here. We concluded from this study that, regardless of the habitat type, the density of bees from the summer phenological period is affected by the number of food plant species. Point forest patches are habitats where summer species from the genus Andrena and the cleptoparasitic genera Nomada and Sphecodes achieve their highest abundances. Roadsides negatively affected abundances of wild bees and there were no characteristic species for this type of habitat. We hypothesised that this might be related to the specific ecological part played by this type of habitat.

Abstract Climatic warming is forcing numerous species to shift their ranges poleward, which has been demonstrated for many taxa across the globe. Yet, the influence of habitat types on within- and among-species variations of distribution shifts has rarely been studied, especially so for the non-breeding season. Here, we investigated habitat specific shift distances of northern range margins and directions of the center of gravity based on a long-term dataset of overwintering birds in Finland. Specifically, we explored influences of habitat type, snow cover depths, species’ climatic niche and habitat specialization on range shifts from 1980’s to 2010’s in 81 bird species. Birds overwintering in farmlands shifted significantly more often northwards than birds of the same species in rural and forest habitats, while the northern range margin shift distances did not significantly differ among the habitat types. Snow cover was negatively associated with the eastward shift direction across all habitats, while we found habitat specific relations to snow cover with northward shift directions and northern range margins shift distances. Species with stronger habitat specializations shifted more strongly towards north as compared to generalist species, whereas the climatic niche of bird species only marginally correlated with range shifts, so that cold-dwelling species shifted longer distances and more clearly eastwards. Our study reveals habitat specific patterns linked to snow conditions for overwintering boreal birds and highlights importance of habitat availability and preference in climate driven range shifts.
