<p>We conducted a bird survey in the Assam University campus, Silchar from February 2011 to June 2011.  A total of 73 species of birds belonging to 56 genera, 32 families and 13 orders was recorded. Significantly, the highest number of bird species restricted to only one particular habitat (17 species) was recorded in the forest area called ‘eco-forest’ (χ<sup>2</sup>=18, df=3, P&lt;0.01).  The highest similarity of bird species was found between degraded area and secondary growth area, and the lowest was found between eco-forest and degraded area.  Species richness and dominance of species were more in the eco-forest area.  The diversity of species was more in the secondary growth area. Red-vented Bulbul, Spotted Dove and Red-whiskered Bulbul were the most abundant and frequent bird species found in campus.  The avifaunal diversity in the study area shows the importance of the University campus as an ideal bird habitat. </p>

Point Count Method

With the lack of baseline information on avifauna within Bicol University and the adjacent forest fragment, this research aimed to identify bird species and compare their presence between an urbanized and forest areas. Avian diversity was documented within the Kalikasan Park and Bicol University Main Campus adjacent ecosystems, representing a forest fragment and semi-urbanized ecosystems, respectively. Bird survey was carried out through point count method. Identification was aided by existing taxonomic keys. A total of 44 species were recorded with eleven as Philippine endemics. Lonchura malacca(Chestnut Munia) and Aplonis panayensis (Asian Glossy Starling) were among the most frequently sighted. Bird species sighted was higher in the forest fragment as compared with the main campus area. The study recommends that Bicol University Main campus be transformed into an avian buffer and safe zone for the protection and conservation of these species and to provide policies to maintain high bird diversity.

In order to understand the ecological impact of the rehabilitation of the Félix Houphouët-Boigny University Campus on the bird community, a study was carried out over two months (October-November 2016). The ornithological inventory carried out by the IPA method in five different habitats identified on the campus gave a total species richness of 51 bird species of 41 genera, 27 families and 13 orders for 1374 birds, with H' = 2.93 and J = 0.74. Five species dominate the population (819 individuals, Fr = 59, 61%). These are Bubulcus ibis (9.32 %), Apus affinis (8.95 %), Corvus albus (19.94 %), Ploceus cucullatus (10.48 %), Lonchura cucullata (10.92 %). The most diversified habitat is the Habitations (26 bird species), while the most abundant is the Brush (416 individuals). Only seven species are common to all sampled habitats. Thus, 12 species observed on campus formerly could not be observed during the present study. Similarly, 18 species observed in this study were not observed in the previous study. The profound transformation of the environment following the rehabilitation has led to a slight increase in diversity but a significant drop in numbers. It is therefore important to better understand the different interactions between the components of the habitat and the various species involved. Such data would be crucial in urban planning policies.

Green open spaces can be potential habitats for birds in urban landscapes. Due to high number of land development, the green open spaces in urban landscapes tend to be small and scattered. Indeed, analysis about effectivity of green open spaces as bird habitats in Bogor City and its surroundings is needed. We investigated bird habitat patches on 14 locations in Bogor City and its surroundings. This study aimed to analyze the effectiveness of bird habitat patches for bird species richness using two variables (size and complexity). The data were analyzed using the Pearson Correlation and multiple linear regression. The results showed that there were no significant differences between bird species richness and size of patches. Conversely, there were significant differences between bird species richness and complexity of patches. The Pearson Correlation revealed that there were high correlation between bird species richness and complexity of patches. Finally, we propose three recommendations of green open spaces as bird habitat patches in Bogor City and its surroundings, such as protecting and managing both small and large bird habitat patches, increasing number of vegetation strata and number of vegetation in some strata in small bird habitat patches, and increasing number of vegetation in some strata in large bird habitat patch with low bird speciess richness.

Avifaunal diversity is the measure of species diversity via species richness and evenness. To this aim, avifaunal survey was conducted in the Institute of Forestry Complex, Hetauda from November 2017 to June 2018. Using line transect and point count methods, 132 species of birds were recorded, representing 15 orders and 44 families. Three species of these birds are in IUCN Red List while 90, 27 and 15 species are residential, visitor and migrant respectively. Higher Shannon diversity index (4.47) and Margalef index (18.78) indicate marked diversity and richness of bird species. A high value calculated for the Simpson index (0.98) represents higher evenness within the species individuals. Although, Pielou’s evenness index (0.92) shows uniformity in the species distribution, Shannon index seems to be influenced by diversity index, species richness and evenness values. The avifaunal diversity in the study area shows the importance of the Institute of Forestry Complex as a suitable bird habitat.

Abundance And Diversity

Relative abundance and diversity of insects were studied in the four spots of Chittagong University Campus, from October 2015 to September 2016. The studied insect orders were- Odonata, Orthoptera, Coleoptera, Hymenoptera and Lepidoptera. Two families under Odonata, four under Orthoptera, five under Coleoptera, three families under Hymenoptera and eight under Lepidoptera were examined from the four study spots. Among these, sixteen species of Odonata, eight species of Orthoptera, Coleoptera and Hymenoptera in each and 32 Lepidoptera species were identified. Highest numbers of insects (276) was collected in April'16 and December'15 whereas lowest numbers of insects (201) were collected in October'15. The highest abundance (906) of insects was found in Spot 3 (Hilly area), medium (785) in Spot 1 (Pond area) and lowest (642) and (648) in Spot 2 (Garden area) and Spot 4 (Artificial forest area), respectively. Lepidoptera (1217) was the most dominant order in the four studied spots followed by Odonata (636), Coleoptera (395), Hymenoptera (381) and Orthoptera (352). The average highest species richness, species diversity and species evenness were observed in October'15 (2.40 ± 0.11), August'16 (2.22 ± 0.03) and August'16 (0.96 ± 0.01), respectively and lowest in April'16 (2.18 ± 0.04), April'16 (1.98 ± 0.07) and April'16 (0.85 ± 0.03), respectively. During the study period, the highest species richness was observed in Spot 2 and Spot 4 (2.32 ± 0.03) and lowest in Spot 3 (2.13 ± 0.02); the highest species diversity was observed in Spot 3 (2.16 ± 0.02) and lowest in Spot 1 and Spot 2 (2.04 ± 0.03); and the highest species evenness was observed in Spot 3 (0.93 ± 0.01) and lowest in Spot 1 and Spot 2 (0.88 ± 0.01). Abundance and diversity of insects were dependent on seasonal fluctuation, and also on ecological and environmental conditions.J. Biodivers. Conserv. Bioresour. Manag. 2017, 3(1): 55-64

Aves species is very abundant in the forest area of Indonesia and its biodiversity is influenced by a number of environmental quality parameters. This research aimed to determine the level of species diversity and abundance of aves species in forest areas of Padang, West Sumatra, Indonesia. The second purpose of this study was to determine factors affecting of diversity and abundance of aves species. The method of this research used bird survey technique (method list of 20 species of birds). This method can be used to complete the list of bird species was found in the forest area, using the quantity of bird species that have been observed. To restrict it, we can use 20 species of aves. Based on this study, in the forest area of UNAND have 21 species of aves. Based on the relative abundance of bird species, the birds most commonly found are species of wallet. Whereas some other aves species have a relative abundance slightly. This happens because of disruption of habitat for aves and forests area by human activities.Keywords : distribution, aves species, measuring of biodiversity

Functional Evenness

ContextThe negative association between elevation and species richness is a well-recognized pattern in macro-ecology. ObjectivesThe aim of this study was to investigate changes in functional evenness of breeding bird communities along an elevation gradient in Europe. MethodsUsing the bird data from the EBCC Atlas of European Breeding Birds we estimated an index of functional evenness which can be assumed as a measure of the potential resilience of communities.ResultsOur findings confirm the existence of a negative association between elevation and bird species richness in all European eco regions. However, we also explored a novel aspect of this relationship, important for conservation: Our findings provide evidence at large spatial scale of a negative association between the functional evenness (potential community resilience) and elevation, independent of the eco region. We also found that the Natura2000 protected areas covers the territory most in need of protection, those characterized by bird communities with low potential resilience, in hilly and mountainous areas.ConclusionsThese results draw attention to European areas occupied by bird communities characterized by a potential lower capacity to respond to strong ecological changes, and, therefore, potentially more exposed to risks for conservation.
