Bird-Ecosystem Relationship in an Urbanizing Habitat: Implications for Conservation and Ecosystem Stability

This study explores the association between birds and their urbanizing ecosystems. The study area was divided into 4 quadrats of area 2700 m2 each. Bird species as well as number of individuals of each species were counted using the Line Transect Method. Statistical analysis of the data was performed using Windows Microsoft Excel and SPSS v.28. The investigation revealed a significant correlation (P < 0.05) between bird species and the four distinct sites within the study area. These sites exhibit variations in vegetation composition and include notable features like water bodies. The findings underscore the heavy reliance of certain bird species in this region on specific types of vegetation for their survival and well-being. Removing even a single plant species could potentially disrupt the entire ecosystem. The study documented the presence of 42 bird species across 30 families, including one vulnerable species. Both local and seasonal migratory birds were observed during the research. Although the study identified a decline in bird diversity within the study area, it remains species-rich, displaying moderate to high diversity (Simpson’s Dominance Index: 0.0319; Margalef’s Richness Index: 4.0754). This research emphasizes the critical importance of conserving bird species and their associated vegetation to maintain ecosystem integrity. Strategic sustainable development practices along with habitat enrichment for birds is recommended to maintain the valuable avifaunal diversity of the study area. By highlighting the intricate relationship between birds and their habitat, the study highlights the significance of conservation efforts in safeguarding the overall health of the ecosystem.

Marine debris characteristics in various coastal typologies in the Gunungkidul coastal area of Yogyakarta—Indonesia

Marine debris is one of the environmental issues that can be brought on by rapid human development and activity, including marine tourism, like what happened in the coastal area of Gunungkidul, Indonesia. The issue of marine debris might decrease the environmental quality and impact tourism in Gunungkidul. This study aims to identify the characteristics of coastal typologies in Gunungkidul and analyze their influence on the characteristics of marine debris. Google Earth images and the Digital Elevation Model were used to interpret and classify the typology across the study area based on their physical characteristics. Marine debris samples, either macro or meso-sized, were collected using the transect method for each beach. Based on the imagery interpretation combined with elevation data from DEMNAS, there are three typologies in the Gunungkidul coastal area, i.e., pocket, non-pocket, and cliff beaches. Cliff typology was eliminated and only pocket and non-pocket beaches were used as marine debris sample collection locations. Hence, four beaches were chosen as study areas, i.e., Seruni, Drini, Sepanjang, and Sedahan; each represents each coastal typology. About 193 macro-sized and 217 meso-sized debris were found in our research area, totaling 1380.31 g. Compared to non-pocket beaches, pocket beaches contain more marine debris. The higher slopes of the pocket beach typology will trap marine debris and make it challenging to reenter the water. On pocket beaches, oceanographic processes concentrate marine debris in one location. Still, on non-pocket beaches, marine debris can disperse and return to the sea more readily due to the cycling of currents near the coast.

USG matrix analysis and power interest to improve community environmental awareness: A case study of mangrove land cover to support community and environmental education

This study employed a mixed-method approach to analyze the composition of mangrove forests. The transect method and remote sensing through supervised classification using Google Earth Engine (GEE) were utilized to assess changes in mangrove areas in 2017, 2019, and 2021. The findings suggest that this study should be included in population and environmental education courses. The results revealed that Avicennia marina mangroves had the highest importance index (INP) values at three different locations. Between 2017 and 2019, mangrove areas decreased from 30.62 hectares to 27.98 hectares. However, from 2019 to 2021, the mangrove area increased from 27.98 hectares to 29.18 hectares, largely due to reforestation efforts in the Pulau Dua Nature Reserve. The NDVI (Normalized Difference Vegetation Index) values indicated "bushy" criteria, ranging from 0.43 to 1.00. The Normalized Difference Mangrove Index (NDMI) values fell into the "Rare" (-1.00 to 0.32) and "Medium" (0.33 to 0.43) categories. The Urgency, Seriousness, and Growth (USG) matrix analysis and Power Interest assessment identified illegal logging, erosion, and waste as significant causes of mangrove decline. Stakeholders, including village chiefs, religious leaders, traditional leaders, and youth leaders, must focus on preserving the mangrove ecosystem in the CAPD. The study's results are vital for educational purposes, particularly in population and environmental education courses. These courses should address environmental issues, prevention strategies, and conservation activities, which can be integrated into the curriculum. This will enable youth to contribute effectively to environmental awareness programs.

Avian ecological guilds determined by water quality parameters of ponds in the central plain agroclimatic zone of Punjab State

Aim: The present study investigated the relationship between avian ecological guilds and water quality parameters at three selected village ponds (namely Pond A, B and C) falling in the central plain agroclimatic zone of Punjab State. Methodology: During the monsoon season (July-October 2022), bird populations and habitat utilization were assessed using point count/line transect methods. Water quality parameters were measured following the standard methods of APHA (2023). Results: Twenty-eight bird species comprising of 7 orders and 15 families were identified, representing 12 trophic guilds, 4 habitat guilds and 5 substrate guilds. Pond B showed the best water quality, harbored the most semi-aquatic/aquatic species (9) and highest trophic diversity. Conversely, Pond C revealed the poorest water quality and had the lowest number of aquatic species. Interpretation: Water quality in ponds seemed to play a crucial role in shaping avian community composition and ecological roles. This study underscores the importance of maintaining good water quality in ponds interspersed in an agroecosystem for the diversity of ecological guilds. Study findings have the potential to be extrapolated to thousands of ponds in the Indian agricultural landscape, thereby having far reaching ecological implications.

Harmonizing ecology and society: an integrated analysis of vulture conservation in the Nilgiri Biosphere Reserve, India

The Nilgiri Biosphere Reserve (NBR) in southern India is home to several critically endangered vulture species. This study in Mudumalai Tiger Reserve and Sathyamangalam Tiger Reserve of NBR presents an integrated analysis of vulture conservation efforts focusing on harmonizing ecosystem preservation and community engagement. We assessed the current status of all four vulture species in the NBR using the road transect method, covering 2,040 km with 24 replications (January–December 2021). We undertook covert surveys in 82 veterinary pharmacies across four districts of Tamil Nadu to determine the availability of non-steroidal anti-inflammatory drugs (NSAIDs), considering the 100-km vulture safe zone that included vulture nesting and foraging areas. As practical conservation efforts require active local community participation, our assessments include the perception study of local communities in 20 villages (eight tribal and 12 non-tribal) near vulture habitats. We focused on NSAID usage, considering the impact of numerous socio-economic factors on vulture conservation efforts. We surveyed 540 respondents using detailed questionnaires for these evaluations. The study underlined the need for a comprehensive vulture management plan that balances ecological concerns with the well-being and means of subsistence of surrounding communities. This study is helpful for future conservation efforts in other areas with comparable problems at the nexus of ecology and society.

Factors Affecting the Winter Distribution of Birds in Forests at the Eastern Edge of Europe

We show for the first time the results of a study into the spatial distribution of birds in forests at the eastern edge of Europe (Republic of Tatarstan, Russia) and changes from early to late winter. A transect method was used to census randomly selected plots spread over a large geographical area in the winters 2018/9–2022/3. We used regression and ordination methods to assess the influence of key environmental factors on species richness, total density of birds, biological diversity, and the probabilities of occurrence of individual species. The most abundant bird species in early winter was the Willow Tit, and in the late winter was the Common Redpoll. Compared with the end of the 20th century, the number of wintering bird species has increased in the study area, likely due to climate warming. Species richness, total density, and the Shannon Index of diversity were higher in early winter than in late winter. Species richness and the Shannon Index were also higher at low elevations and in the west of the study region. Our research shows strong ecological-geographical differences in the preferences of individual bird species in the studied forests. However, almost without exception, birds had a higher probability of occurrence at lower elevation and toward the west.

Abundance of humpback whales in the eastern Indian sector of the Southern Ocean in 2018/19 using opportunistic sighting survey data with a note on the occurrence of other cetaceans

Past commercial whaling depleted the humpback whale in the Southern Ocean; however, its population has recovered since hunting was terminated in 1966. Information on abundance is essential not only managing target animals but understanding the ecosystem because the species is one of the main consumers of Antarctic krill. Abundance of this species has not been reported in the eastern Indian sector (80–150°E) of the Southern Ocean since the mid-2000s. A multidisciplinary ecosystem survey focusing on Antarctic krill was conducted in the area by the Japanese research vessel Kaiyo-maru in 2018/19 austral summer. An opportunistic cetacean sighting survey (platform of opportunity (POP) survey) was conducted as part of the survey. Four baleen and five toothed whale species were sighted during the sighting survey. Humpback whales (113 schools/178 animals) were most frequently observed, followed by fin whales (15/36). Abundance of humpback whales was estimated as 22,395 individuals (CV = 0.270, 95 % confidence intervals: 13,310–37,663) based on the design-based line transect method. Krill consumption by humpback whales in this area was tentatively estimated as 1.336 million tons, corresponding to 30.9 % of krill biomass, although the amount varied greatly depending on the consumption rate’s assumption. The estimated abundance was comparable with previous estimates, however, there are some caveats in interpreting the results. As no approaching whale sightings were made during this POP survey, the proportion of sightings of unidentified large whales was high, possibly leading to an underestimation of the abundance. Dedicated sighting surveys are desirable to obtain more accurate and unbiased abundance estimates, especially for management purposes, although the results of this study could be used for ecological studies in combination with other data sets recoded by the multidisciplinary survey.

Different diversity patterns of butterfly and moth assemblages between deciduous and evergreen broad-leaf forests

In this study, we compared the diversity and abundance of two groups of Lepidopteran insects—butterflies and moths—across deciduous (DBL) and evergreen broad-leaved (EBL) tree communities in warm temperate forests. Over three years (from 2018 to 2020) at the Wando Arboretum, we used transect and point methods to sample butterflies and light traps to sample moths. Our findings revealed that the total estimated species richness was higher in EBL compared to DBL. Non-metric multidimensional scaling (NMDS) analysis confirmed distinct moth assemblages between the two tree communities, while butterfly assemblages did not exhibit such separation. The seasonal diversity patterns of butterflies in both forests differed significantly, whereas those of moths exhibited a similar trend with a peak in June. Beta diversity components indicated high turnover rates in moth assemblages across both tree communities and high nestedness in butterfly assemblages within the DBL. Although the diet breadth of butterflies and moths did not significantly differ between the two tree communities, the number of butterfly species per host plant was higher in DBL and that of moths was higher in EBL. Considering the ongoing vegetation transition from DBL to EBL, changes in forest structure—such as canopy openness and tree density—may adversely impact insect communities within DBL.
