    Human activity is the major factor driving the wetland degradation in shallow lakes. Human exploitation of lake wetlands alters the habitats of wintering waterbirds, and, in turn, waterbird diversity in the shallow lakes. In the present study, we surveyed species composition, abundance, and habitat characteristics of waterbirds in three types of wetland habitats . Goals / Objectives (1) Evaluate the role of ecological processes in determining avian community composition and productivity in wetland communities of the Coastal Prairies and East Texas Forests. (2) Determine factors associated with habitats of high biological diversity in bottomland hardwood forest habitats. (3) Develop models which predict responses of key components of .

    We tested these ideas by relating three key aspects of landscape structure (land use type, forest cover and edge density) to measures of avian cross‐habitat spillover. We collected data across 92 paired sampling sites (forest and adjacent matrix habitats, composed of either high‐contrasting cattle pastures or low‐contrasting sun coffee. Coarse-scale forest associations are well known to predict avian responses to land-use change, with forest-dwelling species less tolerant of disturbance than species associated with non-forest habitats [11,16]; the novel aspect of this study involves the fine-scale predictors.

Forest cover positively affects the functional richness for bird assemblages. • At drier regions, avifauna has lower functional and phylogenetic redundancy.

• Less vegetated areas have bird species with less unique ecological functions. • Ongoing climate and land-use changes effects synergistically the avifauna : Isadora Correia, Erivelton Rosário do Nascimento, Sidney F. Gouveia. Land use type was a key factor influencing avian cross‐habitat spillover, facilitating species movement into coffee plantations and acting as a barrier to spillover into cattle pastures.

We found that 24% of the forest‐dependent species pool was capable of spillover into coffee plantations, while spillover was nearly non‐existent in Cited by:   For instance, comparative studies on species diversity in cut and uncut forests include effects of habitat heterogeneity, anthropogenic disturbances and habitat fragmentation (see Didham et al., for a detailed analysis).

Considering the high frequency of avian studies, well‐known disturbance effects of forest management on bird breeding. ABSTRACT:Habitat effect on the Abundance and Diversity of avian species was studied in Idanre Forest Reserve, South West Nigeria.

The study area was divided into three compartments based on their different land use types. A total of 30 transect lines were randomly laid out and 10 transect lines per a compartment. Land use change—for example, the conversion of natural habitats to agricultural or urban ecosystems—is widely recognized to influence the risk and.

Although habitat loss is the predominant factor leading to biodiversity loss in the Anthropocene 1,2, exactly how this loss manifests—and at which scales—remains a central debate 3,4,5, Forest fragmentation and degradation leads to formation of modified habitats whose ability to support existing avifaunal diversity is still largely unknown.

Bird diversity in indigenous forest, disturbed forest, plantation forest and farmlands adjacent to North Nandi Forest reserve was studied between January and June   Since the magnitude of edge effects depend on the land use next to habitat, our results highlight that – besides increasing habitat amount – reducing total length of edges and/or edge contrast and thereby the extent of edge effects in intermediate to high forested landscapes may be a very effective tool in maximizing species retention (e.g.

Habitat effects on avian hematozoa: birds. For parasite transmission to occur, the parasite must be in the correct life stage, the bird must be susceptible to the parasite, the vector must be present and competent, and the environment must be permissive (Fig. 1).Since birds are warm blooded, they serve as a constant and relatively safe environment for the blood parasites that.

Large herbivores directly and indirectly influence ecosystem function, positively and negatively affecting diversity of plants and animals, including birds.

Such cascading effects are clearly important, particularly given ongoing global declines in large herbivores and many avian communities. We examined relationships between bird diversity (species richness and. Quantifying patterns is a key element of landscape analysis.

One aspect of this quantification of particular importance to landscape ecologists is the classification of continuous variables to produce categorical variables such as land-cover type or elevation stratum. Although landscape ecologists are fully aware of the importance of spatial resolution in ecological investigations.

There was a significant difference in bird diversity in the four habitats where Secondary forest had the highest diversity of and sugarcane plantations had a diversity of while human settlement and mixed firms had lower diversities of and respectively(df1 = 2, df2 = F =P = ).

Keywords. Also, the consequences of land use changes have been addressed by studies focusing on the perceived effects of habitat loss on biodiversity at regional and broader geographic scales (Banks-Leite.

A number of studies investigated changes to bird communities by comparing an urbanized site versus a less urbanized (or more forested) site. Many investigators found that urbanization decreased the species diversity of the avian community and increased avian density (or bird biomass), favoring dominance by a few species.

63 pp. of Understory Diversity in Degraded Pasturelands of Costa Rica. Forest Ecology and Management Bird’s species diversity and abundance are being threatened due to agricultural activities and anthropogenic practices which causes habitat destruction and fragmentation.

Understanding how avian species respond to habitat destruction is important towards development of effective measures to ensure that the environment is protected. A study on avian abundance, diversity. Influence of Land-Use Type on Bird Species Richness and Forest Dependent Guilds. The relative richness of forest specialist and generalist species was high in natural forest while farmlands had a higher richness of nonforest habitat dependent guilds (Figure 3).The three land-use types showed significant differences in relative richness of various habitat dependent guilds, forest.

Additionally, the positive effect of forest edges on bird species richness and total abundance mainly resulted from the addition of species from both sides of the edge (and particularly from forest habitats) as very few species were true edge‐specialists in this study (see Imbeau et al.

). Even if results were statistically significant.I ascertain the wildlife fauna in different habitats, i.e., mangrove forests, mudflats, freshwater wetlands, dry lands, scrub lands, forests, riverine forest, and waterlogged areas.

In addition, I. “Igune,” a traditional agricultural landscape in the Tohoku region of Japan, is characterized by small-scale artificial woodlots surrounding a farmer’s house that are interspersed with paddy fields. During the rapid economic growth of Japan over recent decades, some igune woodlots have been abandoned or logged.

Biodiversity conservation is an important issue .
