Abstract:
Steppe ecosystems worldwide are affected by agricultural development and generally unprotected. Spanish shrub-steppes contain endangered avifauna, and this paper analyses their state of habitat conservation, the changes that have occurred in the last decade, primary productivity and its relationship with land exploitation and the richness of threatened birds, and avifauna responses to habitat loss. Fifty steppe remnants distributed throughout Spain and inhabited by Dupont's lark Chersophilus duponti, an endangered passerine representative of shrub steppe-like habitat, were studied. The study f

In the recreational zone of "Homilshanski Lisy" National Park 137 species of birds were identified during the period 1980–2015, of which 127 species nest, 8 winter, and 2 observed during the spring migration. The nesting species are distributed in 4 ecological groups dominated by dendrophylls (67 species), with fewer limnophylls-fresh water species (29), campophylls-open country species (16) and sclerophylls (11). Among the nesting birds 11 landscape-genetic faunal assemblages were distinguished, dominated by typical nemoral-woodland (19%), tropical (14%) and forest-steppe (13%) species. The a

Forest biogeocenosis is a necessary environment for the normal existence of many species of wild animals, including birds. Recently, however, a gradual decrease in their numbers is observed in most forest areas of the Forest-Steppe zone.

In this regard, specialists-zoologists, ornithologists, etc. pay great attention to the study of this issue (Koval' N.F. 1982).

Approximately 50-60% of native sagebrush steppe has been lost to non-native grasses, which has contributed to population decreases for sagebrush-associated songbirds. Removal of non-native grasses and restoration treatments may return structure and function of sagebrush steppe and ultimately benefit songbirds, but their responses must be evaluated. To determine breeding songbird community responses to sagebrush restoration treatments, in 2013 we conducted bird surveys at restored plots at the Kelly Hayfields restoration area in Grand Teton National Park, Wyoming.

Changes in nesting conditions cause a change in the number of individual species, ecological groups, and, consequently, the structure of the bird community. The purpose of the study is to analyze the possibilities and directions – the transformations of the communitys of nesting birds in the process of reorganization of the forest ecosystem into a park. The material was collected in the territory of one of the forest parks in the Kiev city. Forest is an mixed based on Quercus robur L., Carpinus betulus L., Acer platanoides L., Tilia cordata L., Fraxinus excelsior L. There are individual trees

AbstractPopulations of North American grassland birds have suffered drastic declines. The causes of these declines are only partially understood and may vary among regions. During the 2004 and 2005 breeding seasons we recorded survival information from 220 nests of four bird species in nine study sites representing three habitat types of the desert grasslands of central Mexico, where grassland birds had not yet been studied. We predicted that land-use change from shortgrass steppe to heavily grazed savannah-type grasslands and agriculture would negatively affect nesting success, number of fled

SummaryCounts of breeding birds in fallow land of Castro Verde region, the main steppe area of Portugal, were carried out during the spring of 1994, and the population densities of the most common species were estimated. The bird community is relatively simple, with a low species richness and diversity. Nevertheless, it includes several species with unfavourable conservation status. The most common species were Calandra Lark Melanocorypha calandra and Little Bustard Tetrax tetrax, with a mean density of, respectively, 5.6 and 2.6 males/10 ha.

Birds are important components of biodiversity and acts as an indicator of habitat quality, productivity and stability. This study aimed to document species richness and assess the temporal distribution pattern of globally threatened bird species in the Basanta Protected Forest (BPF), one of the largest corridor forests which connects Dudhwa National Park (India) with protected areas of western lowland Nepal. During study period of ten years from 2010 to 2019, a total of 381 bird species from 78 families of 19 orders were recorded. Order Passeriformes had the highest species richness (n=180) f

Abstract:
Abstract Sagebrush communities, covering millions of hectares in the western United States, are among our most imperiled ecosystems. They are challenged by various anthropogenic stressors, including invasion by nonnative grasses that degrade habitat quality and alter ecosystem function. Sagebrush restoration efforts are underway to improve habitat conditions to benefit a wide range of sagebrush-dependent species. Because birds are good indicators of habitat quality, monitoring avian metrics is an effective way to measure progress of sagebrush restoration. We compared avian community compositio

The greatest number of breeding species and the most abundant species are in the first group (cereals, flax, white mustard, and buckwheat).

SummaryLocal changes in land use can influence patterns of habitat selection by farmland birds, thus biasing predictions of population responses to land use changes based on wildlife-habitat or niche modelling. This study, based in arable farmland in south-central Spain, determined whether habitat selection (use of agricultural habitats and the distance to roads, tracks and buildings) by Great Bustards Otis tarda varied between two nearby areas with differing land uses. The western sector has experienced a process of land abandonment and infrastructure development linked to an airport project

In settlements, safe places for birds nesting and feeding need to be created. The purpose of the work is to assess the state and identify vectors of the formation of nesting bird communities in parks under the pressure of anthropic load in the metropolis. In parks of Kyiv 62 species of birds nest. Such faunogenetic complexes like European nemoral (25.0–53.3%), Desert-mountain (12.0–27.8%) and Forest-steppe (6.9–25.0%) prevail. The number of community species in each of parks is 49–12, the average nesting density is 0.08±0.02–0.9±0.19 pairs / ha, and the dispersion is 0.12–1.62. With the combin
