Abstract:

Abstract 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 c

Abstract:

The world has been encountering a COVID-19 pandemic since late 2019. The world’s people have also witnessed the free movement of wildlife, even in many urban areas in some countries during the imposed lockdown. We conducted research on the birds in the urban landscape of Jamalpur Sadar upazila from March 2020 to October 2020 during this pandemic situation. A total of 134 species of birds with 4338 individuals were recorded during the study period. The number of resident bird species was the maximum (115 species, 85.82%) compared to migrants.

Abstract:

Nectarivorous birds and bird-pollinated plants are linked by a network of interactions. Here I ask how these interactions influence evolution and community composition. I find near complete evidence for the effect of birds on plant evolution. Experiments show the process in action—birds select among floral phenotypes in a population—and comparative studies find the resulting pattern—bird-pollinated species have long-tubed, red flowers with large nectar volumes. Speciation is accomplished in one “magical” step when adaptation for bird pollination brings about divergent morphology and reproducti

Abstract:

Padjadjaran University (UNPAD) Jatinangor is currently conducting green Campus program. To support the program, a study of biota living in it, as one of the benchmarks of good or bad environmental conditions, is needed. The green space of Jatinangor Campus is divided into two clusters namely Cluster I green space (Campus Forest) and green space Cluster II (Campus Non Forest). The objective of the research was to know the relationship between diversity of birds with diversity of plants in the green space of Cluster I (Campus Forest) and Cluster II (Campus Non Forest) UNPAD Campus Jatinangor as

Nickel mining is one of open type mining having a high risk on environment. Birds are often used as indicators of habitat change in reclaimed mine-land. The objectives of this study were (1) to identify bird species; (2) to compare bird communities; (3) to predict biotic and abiotic factors that affect bird communities in mining reclamation land according to the age of reclamation, and natural forest in nickel mining area. This research was conducted on reclaimed land in 2006, 2007, 2008, 2009. The composition of bird species is described based on family, endemicity and feeding guild. Bird dat

The Chicago River’s north branch intersects multiple urban land uses, including residential, industrial, commercial, and recreational. The north branch also supports a diversity of birds exploiting a variety of resources and structures along the river as habitat. From three breeding seasons of point count surveys, I assess the breeding bird communities in four different sections, representing four different restoration or management styles. These four river sections are also very different with regards to the surrounding neighborhood demographics. These data serve as both a baseline for future

Forest age ranged from 91 to 150 years and the ecosystems ranged from 500 to 2100 m above sea level. Sampled forest stands had no previous history of logging and were a minimum 30 ha in size. The main objectives of this study were to measure nonmigratory birds in relation to elevation and to percentage of stand-level lodgepole pine composition. Twenty-one nonmigratory bird species totaling 2747 observations were detected at 775 point

Abstract:

Forest ecosystems contain many tree-related microhabitats (TreMs), which are used by various groups of organisms. Birds use TreMs for shelter, foraging and breeding. The abundance and variability of TreMs is related to tree stand composition and age. Over the last few centuries there has been a drastic decline in the structural and biological diversity of temperate forests over large areas of the Northern Hemisphere. These changes have reduced the diversity and quantity of TreMs. In this study we showed the relationships between stand composition, the abundance of TreMs, and the species richne
