“…The decrease in species richness at the mine region also led to a shrink of PD, MPFD, and MPD ( Figure 4C , D ). Similar results were found in Russia ( Belskii and Mikryukov 2018 ) and the Sierra de Guadalupe, Mexico ( Ibarra-Meza et al 2022 ). The shrink of PD, MPFD, and MPD reflected a loss of species with special trait combinations, suggesting that species that fulfil specialized functional roles disappear successively at the mine region.…”

Understanding the mechanisms of community assembly is a key question in ecology. Metal pollution may result in significant changes in bird community structure and diversity, with implications for ecosystem processes and function. However, the relative importance of these processes in shaping the bird community at the polluted area is still not clear. Here, we explored bird species richness, functional, and phylogenetic diversity, and the assembly processes of community at the mine region of southwest China. Our results showed that the three dimensions of diversity at the mine area were lower than that at the reference sites. In the community assembly, the result was 0 < NRI / NFRI < 1.96, which indicated deterministic processes (environmental filtering) might drive community clustering. The results of the neutral community model, and normalized stochasticity ratio, showed the dominant role of stochastic processes in shaping the bird community assembly. We further quantified the community-level habitat niche breadth (Bcom), and we found that there was no difference in Bcom-value between the mine area and reference sites. This indicates that the bird communities at the mine area and three reference sites were not subjected to extreme environmental selection (same or different resource allocation) to form a highly specialized niche. These findings provide insights into the distribution patterns and dominant ecological processes of bird communities under metal exposure, and extend the knowledge in community assembly mechanisms of bird communities living in the mine area.

“…This increased bird diversity and the changes in community composition may be due to improved water quality (unfortunately, preremediation data on water quality are limited, so we cannot provide a thorough test) as well as the improved physical characteristics of the TSE ponds compared to the lagoons prior to remediation (see Section 4.2). Supporting this interpretation, the abundance of individuals and the diversity of bird species are known to be negatively impacted by pollutants in other contexts (e.g., heavy metal pollution from smelting [38]; electronic waste from recycling centers [39]; agricultural chemicals [40]; urban air pollution [41]). Unfortunately, the preand post-remediation surveys were conducted by different observers, which may add error to the pre-and post-remediation comparison.…”

Qatar, a peninsular country in the Persian Gulf, is significant to avian species due to its location along the African–Eurasian Flyway, a key migratory path. Receiving untreated domestic and industrial liquid waste from Qatar in the past, Al Karaana Lagoons have since been reconstructed as an artificial wetland to address the growing environmental concern posed by contamination build-up. This study documents the changes in biodiversity at Al Karaana Lagoons following their environmental remediation. Data collected (2015 and 2017) by Ashghal (Public Works Authority) prior to project implementation was analyzed alongside data collected independently following project completion (2019–2021). There was a marked increase in bird biodiversity following remediation, including substantial use by migratory species and resident breeders. Further analysis of water quality data of the TSE (treated sewage effluent) ponds shows that they are eutrophic but still support substantial bird life. The project’s success demonstrates how reclaimed lands can provide important habitats to local and migratory birds and encourages similar restoration efforts in the future in both Qatar and elsewhere. We call for the continued monitoring of the site and the implementation of guidelines for the use of the site that balance human activities and habitat quality.
