Habitat quality, urbanisation & pesticides influence bird abundance and richness in gardens

Gardens are regularly portrayed as green oases, refuges for wildlife that has been displaced from the countryside by intensive farming practices which have reduced habitat availability. Pesticides also commonly used in urban areas, but few studies investigated their impacts. In this study, we explored how bird richness and abundance gardens across UK influenced quality, urbanisation level pesticide practices. To achieve this, collaborated with British Trust Ornithology (BTO) runs Garden Birdwatch, a citizen-science-based garden recording scheme. Participants study were asked to complete questionnaire about practice. From 615 provided useful data, found 32.2 % applied pesticides glyphosate comprised 53.3 of these applications.

Short-time acoustic indices for monitoring urban-natural environments using artificial neural networks

Ecological Indicators, Journal Year: 2024, Volume and Issue: 160, P. 111775 - 111775

Published: Feb. 28, 2024

Urban-natural environments, proximal to rapidly urbanizing cities, provide essential ecosystem functions that benefit both city residents and ecological communities. With escalating urbanization, the resilience of these ecosystems is being progressively challenged, highlighting need for robust monitoring mechanisms. Acoustic has emerged as an unobtrusive method evaluate status capitalizing on indicators reflect landscape features specific acoustic events. Despite potentially offering significant insights, this approach generates a large volume data, introducing complexities in subsequent analyses. To mitigate this, we propose integrating artificial neural networks with indices enhance data analysis. Our emphasizes usefulness short-time indices, computed over finite-duration analysis windows, polyphonic sound event detection accuracy. Empirical results support performance our approach, registering F1-Score error rate 0.614. Overall, study delineates novel paradigm geared towards enhancing or preserving biological diversity urban-natural environments areas population growth urban development.

Effects of Vegetation on Bird Communities and Bird–Plant Interactions in Urban Green Areas of Riparian Forests in Brazil That Have Undergone Ecological Restoration

Diversity, Journal Year: 2025, Volume and Issue: 17(3), P. 149 - 149

Published: Feb. 22, 2025

Urbanization replaces natural vegetation for city expansion, impacting environmental and climatic variables that affect the health of human population fauna. These changes important groups such as birds, given their greater sensitivity to anthropogenic alterations, especially when we understand these effects on a large scale, considering countries Brazil, which represents third country with greatest diversity bird species in world. Conversely, green spaces like urban parks, tree-lined avenues, riparian forests seem foster biodiversity conservation. Here, analyze communities bird–plant interactions areas have undergone ecological restoration. The study was carried out between January October 2019 two restored Uberlândia, Brazil. Results showed richness birds observed Praia Clube (n = 86) Parque Linear Rio Uberabinha 80). most representative trophic guilds areas, highest proportion relative abundances during both seasons, were granivores, omnivores, insectivores, frugivores. Composition varied significantly function plant community, particularly interaction season area (ANOSIM: R 0.19; Stress 0.10; p 0.008). In environments dominated by generalist synanthropic (Eared Dove, Picazuro Pigeon), effective planning management are crucial. It is acknowledge certain depend specific habitats, forests, within vital specialized species, endemic Brazilian Savanna or Cerrado restricted Brazil (White-striped Warbler) vulnerable categories globally (Bare-faced Curassow). Therefore, restoration efforts degraded should be carefully planned restore conserve effectively.

From town to town: Predicting the taxonomic, functional and phylogenetic diversity of birds using NDVI

Ecological Indicators, Journal Year: 2020, Volume and Issue: 119, P. 106703 - 106703

Published: Aug. 11, 2020

Biodiversity mapping in urban areas is imperative for their conservation. Remote sensors produce environmental information, such as the Normalized Difference Vegetation Index (NDVI), an indicator of vegetation cover areas. NDVI can be used to predict taxonomic, functional and phylogenetic bird diversity Moreover, a predictive model constructed one city other cities. The objectives this study were: 1) construct evaluate models between birds Mar del Plata city, Argentina; 2) extrapolate these two cities region: Balcarce Miramar. Generalized additive were applied relate variations NDVI. In Plata, taxonomic increased with increasing values, explained 64–81% variation. correctly predicted values additional transects not included models, although they had low power diversity. adequately spatial variation species (Shannon index) Miramar, richness Balcarce, Our analysis revealed that based on patterns created also depict expected cities, being time-saving cost-effective method create tool biodiversity
