Collection of data on avifaunal diversity is a crucial component for monitoring the effects of habitat changes on biodiversity. A rapid cross sectional survey to document common bird species present in Kabale municipality was conducted over a period of 3 months. Birds were categorized into families and the Shannon–Weaver (H') diversity index and the abundance of all the species was calculated. A total of 1770 bird individuals consisting of 67 species, 34 families were recorded, with an overall species diversity of 3.41. The Grey Crowned Crane (Balearica regulorum) an endangered species and the Woolly–necked Stork (Ciconia episcopus) a vulnerable species were among the species recorded. The relatively high diversity is probably attributed to the presence of trees on farmland areas within the municipality. This combination seems to provide various food sources or nesting and perching grounds for the birds. Information generated by this study will serve as a benchmark for monitoring of changes in species diversity and composition over time. In addition, the list of birds will be useful to residents of the area and the many ecotourists who visit Kabale town.

A comprehensive inventory of faunal biodiversity was conducted within three Key Biodiversity Areas of Central Visayas. Mt. Bandilaan Natural Park (MBNP), Balinsasayao Twin Lakes Natural Park (BTLNP), and Rajah Sikatuna Protected Landscape (RSPL). Three primary wildlife groups were surveyed: bats, birds and amphibians. Species diversity and population trends were then analyzed to assess areas of biodiversity importance. RSPL generally had the highest species richness and diversity index while MBNP consistently had the lowest. When pooled. The surveyed areas resulted in a high diversity index and rate of endemicity showing the importance of multiple areas of protection. These findings can be utilized to prioritize habitat protection as well as to serve as a baseline information for future biodiversity inventories. J. Biodivers. Conserv. Bioresour.

Background: There is little evidence about salt intake and its food sources in the Iranian population, especially in children and adolescents. Aims: To investigate salt intake and dietary sources in Isfahan, Islamic Republic of Iran. Methods: This was a cross-sectional survey conducted in 2014–2015. We randomly selected 1384 adults (50.3% female, 49.7% male) aged > 18 years [mean 37.9 (10.6) years], and 786 children and adolescents (50.9% male, 49.1% female) aged 618 years [mean 12.5 (3.4) years]. All participants underwent a dietary assessment for salt intake, using a validated food frequency questionnaire. Results: The total salt intake was 10.9 (3.4) g/day in adults and 10.3 (2.9) g/day in children and adolescents. Added salt was the primary source of salt intake, followed by bread and cheese in both groups. Salt intake was related significantly to being younger, male, a smoker, less educated and physically active in the adult group. In children and adolescents, it was significantly associated with increasing age, male sex, low physical activity and parents’ education level (all P < 0.05). Conclusions: Salt intake in Isfahan was more than twice that recommended by the World Health Organization. The main source of sodium was added salt, followed bread and cheese. Future national studies are warranted to assess the dietary salt intake and its main sources in different provinces in the Islamic Republic of Iran.

Forest is the most significant habitat for birds by supporting around 75% of all bird species while only 45% of all bird species have adapted to humans modified habitats. The research was conducted in the Montane Forest Research Station, Jos, Plateau State, in other to determine the abundance, diversity and effect of habitat types on bird’s species diversity. Fifteen transects of 200m were laid in the three habitat types (riparian forest, farmland and residential area) using stratified random sampling method. The data collected were analysed using R console. Shannon Weiner diversity index was used to analyse species diversity while generalized linear model was used to determine the effect of the habitat variables on bird species diversity. The result showed a total number of 1466 individual birds belonging to 17 families and 60 bird species were sighted. The abundance of birds was highest in riparian forest (2252), farmland (1732) and Residential area (1094) with no significance difference (p=0.177). Species richness was higher in the riparian forest (57), farmland (49), and the residential area (44). It also revealed that bird diversity index was highly significant. Riparian forest had the highest diversity (4.77), and the species were more evenly distributed (0.6) as compared to the other habitat types. The higher the number of trees and canopy cover the higher the diversity of species as was observed in the riparian forest where forest species that weren’t seen in the other habitats were found. The farmland and residential areas also hold a considerable number of some generalist bird species due to some patches of vegetation found in the habitat. Therefore, conservation efforts should be directed towards keeping vegetation intact in human dominated areas, as it serves as repository for bird species which are ecologically important. Hence, planting trees (economic, fruit and ornamental) should be encouraged.

Abstract. Izzati U, Hasibuan HS. 2019. Riparian tree and bird diversity in Cisadane River, South Tangerang City, Indonesia. Biodiversitas 20: 595-603. Riparian is a riverbank area that has unique characteristics. It is a combination of terrestrial with aquatic habitats so that riparian ecosystems have high biodiversity values. Riparian is included in a protected area that is naturally designated for vegetation, but in reality, riparian areas, especially in urban areas, have a lot of conversion of land functions by humans so that it can disrupt diversity of tree and bird species. This study aims to identify the diversity of tree and bird species and the correlation between the two. Riparian length of Cisadane River, South Tangerang City is 20.15 km. The method used was plot line with size of 20 m x 20 m for tree data and line transect for bird data by systematic sampling with a random start then analyzed using Shannon Wiener index. The results obtained were found 22 tree species included in 11 families with species diversity index (H') of 2.707 and 40 bird species belonging to 25 families with species diversity index (H') of 2.794. The diversity of tree and bird species is classified as medium. The results of the analysis using the Pearson correlation between the diversity of tree with bird species obtained that there was no relationship between the two. Based on these results, riparian zones in urban areas need to be maintained and improved in quality so that the diversity of tree and bird species increases so as to create a stable ecosystem.

Indonesia has a high diversity of ant species, but much remains unreported. In agricultural habitats, ants can act as predators, decomposers, and bioindicators for agricultural ecosystems health. This research aimed to study the species diversity of Formicidae on tidal swamp rice fields in Indragiri Hilir District. Sampling was carried out in two periods of rice planting. Samples were conducted in 4 sub-districts of rice production centers, namely BatangTuaka, Keritang, Reteh, and Tembilahan Hulu, using four sampling techniques (i.e., insect net, malaise trap, yellow pan trap, and pitfall trap). Diversity index (H ), Species richness index (d), Species Evenness index (J), and Similarity Index (Is) were calculated. We found 5,754 individuals consisting of 5 subfamilies and 43 species of Formicidae at the four studied areas. Subfamily Myrmicinaehas the highest individual abundance, 2.578 individuals, followed by subfamily Formicinae1.823 individuals, subfamily Ponerinae 776 individuals, subfamily Dolichoderinae 575 individuals, and subfamily Pseudomyrmecinae 2 individuals. Diversity of plant species and environmental factors can affect the diversity index, species abundance, and abundance of individual Ants.

Background: Long-lasting insecticide treated nets (LLINs) remain a cornerstone of malaria control, but optimal distribution strategies to sustain universal coverage are not well defined Methods: We conducted a cross sectional survey of 2,190 households in the highlands of western Uganda to examine LLIN source and use among children age with elevation and distance to clinic being the primary variables of interest. Results: We found that only 64.7% (95% CI 64.0 to 65.5%) of children were reported to have slept under a LLIN the previous night. Compared to those living <1 km from a health center, households at ≥ 2 km were less likely to report the child sleeping under a LLIN (RR 0.86, 95% CI: 0.83 to 0.89, p<.001). Households located farther from a health center received a higher proportion of nets from government distributions compared to households living closer to health centers. Conclusions: Continuous, clinic based distribution efforts were insufficient to sustain high rates of LLIN use among children between mass distribution campaigns. More frequent campaigns and complementary approaches are required to achieve and maintain universal LLIN coverage in rural areas.

The diversity of ant species is one of the links in ecosystem stability as decomposing insects as well as food sources so that its existence becomes very ecologically important. Information about the types of ants found in the urban forest of Ketapang Regency is not yet available, therefore the problem of this research is how the diversity of ant species (Formicidae) in the urban forest of Ketapang Regency. This study aims to document the richness and diversity of ant species in the urban forest of Ketapang Regency, West Kalimantan. The method used was purposive sampling and systematic where the placement of traps was carried out according to the presence of ants in terrestrial and arboreal types in secondary forest habitats. Based on the results of research in the urban forest of Ketapang Regency, which was carried out in two types, namely terrestrial type and arboreal type, 10 species of 5 sub-families were found. Sub-families and types of ants found include: Dolichoderinae (Dolichoderus burmanicus, Dolichoderus taprobanae ceramensis), Formicinae (Aphomomyrmex afer, Polirachis browni, Prenolepis fisheri, Chepalotes femoral), Myrmicinae (Crematogester yameni, Crematogester indet), Ponerinae (Odontomachus haematodus), Pseudomyrmecinae (Tetraponera attenuata). The species diversity index (H') in terrestrial type secondary forest habitat (H'= 0.62) and arboreal type (H'= 0.81), the results of the two types in the secondary forest can be concluded that it is still relatively low.Keywords: Ants, Secondary forest habitat, Species diversity

High Diversity

Predictions from theory, field data, and experiments have shown that high landscape connectivity promotes higher species richness than low connectivity. However, examples demonstrating high diversity in low connected landscapes also exist. Here we describe the many factors that drive landscape connectivity at different spatiotemporal scales by varying the amplitude and frequency of changes in the dispersal radius of spatial networks. We found that the fluctuations of landscape connectivity support metacommunities with higher species richness than static landscapes. Our results also show a dispersal radius threshold below which species richness drops dramatically in static landscapes. Such a threshold is not observed in dynamic landscapes for a broad range of amplitude and frequency values determining landscape connectivity. We conclude that merging amplitude and frequency as drivers of landscape connectivity together with patch dynamics into metacommunity theory can provide new testable predictions about species diversity in rapidly changing landscapes.

Background: Birds are one component of biodiversity. Ethiopia is rich in biodiversity resources. The avian diversity record is far from complete. There is no scientifically documented information on bird species composition and abundance at Nensebo forest. The objective of the study was to assess species composition, relative abundance and distribution of birds at Nensebo forest in southern Ethiopia. Methods: We employed a stratified random sampling technique with our study area stratified into two dominant habitat types: moist Afromontane forest and modified habitat. Within strata, we established 20 transect lines of 1km length and 0.25km width to sample 27.75% of the study area. We used line transect count methods aided by binoculars to estimate avian species diversity and distribution. We employed quantitative biodiversity indices, such as Shannon wiener diversity indexes to compare species diversity among habitat types and two way ANOVA to analyze the effect of season and habitat on bird species richness and abundance. Results: A total of 105 bird species consisting of 1 endemic, 8 near endemic, 1 globally threatened and 9 Palearctic migrants were recorded in Nensebo forest. Species richness and abundance varied between habitat types in Nensebo forest with mean species richness greater in modified habitat (mean= 4.70 ±1.65) as compared to moist Afromontane forest habitat (mean= 3.95 ±4.12, F=94.66 P<0.001). Additionally, modified habitat (Shannon diversity index= 4.131) harbored higher diversity of birds as opposed to Afromontane forest habitat (Shannon diversity index=3.79). Conclusion: The Nensebo forest has high avian species diversity including several endemic and endangered species revealing the importance of this site for bird conservation. Although we found that habitat heterogeneity favored bird species diversity, moist Afromontane habitat is critical for forest obligate species. Hence, sustainable bird conservation strategies including land use planning should be initiated for this area.
