Abstract The Mandalika Special Economic Zone (SEZ) was designated as a tourist area in 2015. The development of the Mandalika area directly impacts the sustainability, diversity of species, especially birds that make mangroves their habitat. The study aims to investigate the value of bird species diversity in mangrove habitats as bioindicators. Furthermore, the research has been carried out for three months, from March to May 2021. Research data collection uses the roaming method, and data analysis uses bird community structure analysis (Diversity Index). In this study, 33 species of birds were found. Furthermore, it was found that six species of birds are protected wildlife. In addition, 16 are migratory birds, and 27 are Least Concern (LC) bird species; four species have Near Threatened (NT) status. Meanwhile, the Index of bird community structure is H’ 2.7, uniformity E 0.8, and dominance C 0.9. The value of the bird community structure in the Mandalika SEZ shows the condition of mangrove habitat in the moderate damage category. Therefore, there needs to be an effort to preserve mangroves involving the community, government, and Indonesia Tourism Development Corporation (ITDC) area managers.

Consistent Change

We experimentally tested the heterospecific attraction hypothesis by manipulating densities of resident birds (black-capped chickadee, Parus atricapillus, red-breasted nuthatch, Sitta canadensis, and white-breasted nuthatch, S. carolinensis) on 7 lake islands in northern Minnesota, U.S.A. Resident numbers were increased by winter feeding and decreased by removals using mist nets. The heterospecific attraction hypothesis states that migrants use residents as a cue to identify the best sites for breeding in a heterogeneous landscape because residents have already selected higher quality sites. The hypothesis predicts that there will be a higher overall density of migrants associated with increased resident density. Results showed that there was a consistent change in migrant bird community structure (i.e., in the relative abundance of species) in response to manipulation. This change resulted mainly from an increased density of arboreal insectivores, i.e., species that belong to the same foraging guild as residents, suggesting that food is an important factor contributing to heterospecific attraction. The red-eyed vireo, Vireo olivaceus, and black-and-white warbler, Mniotilta varia, showed the strongest positive response. No migrant species responded negatively to augmented resident density, suggesting that interspecific competition may be less important in structuring breeding bird communities in northern forests. Our results support the view that positive interactions should be considered when studying community structure.

Rarefaction Analysis

AbstractIn the Indian subcontinent there is hardly any study that compares the bird community structure of urban/suburban areas with those of forest habitat. The present survey identified diverse assemblages of birds in the Pauri district at different elevations. A total of 125 bird species belonging to 40 families including two least count species (Lophura leucomelanos and Pucrasia marcolopha) were recorded during this survey in the forest and urbanized habitats of Pauri District (Garhwal Hiamalaya) of Uttarakhand state, India. The high elevation (Pauri 1600–2100 m a.s.l.), mid elevation (Srikot-Khanda 900–1300 m a.s.l.) and low elevation (Srinagar 500–900 m a.s.l.) contributed 88.8%, 63.2% and 58.4% of the total species respectively. Rarefaction analysis and Shannon diversity index showed that the high elevation forest habitat had highest bird species richness (BSR) and bird species diversity (BSD) followed by the mid and then the low elevation forests. BSR and BSD fluctuated across seasons at all elevations but not across habitat types. Present study provides a base line data about avian community composition in urbanized and natural habitats along altitudinal gradient in the study area. This information may be useful to the conservation biologists for the better management and conservation of the avifauna in the Western Himalaya, a part of one of the hot biodiversity spots of the world.
