Abstract This study examines the accumulation of heavy metals (lead, cadmium, and zinc) in blood house sparrows (Passer domesticus) across various urban habitats Meknes, Morocco. Fifty adult were captured from five distinct sites, including industrial, high-traffic, rural areas. Blood samples analyzed using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES). Results show significant variations metal concentrations depending on site. The highest levels found industrial zone, with lead (Pb) at 336.02 µg/L, cadmium (Cd) 12.28 zinc (Zn) 1736.09 µg/L. Principal Component Analysis (PCA) K-means clustering revealed three pollution clusters: Cluster 0 (high Zn, low Pb Cd), 1 (moderate all metals), 2 metals). These findings highlight ecological health risks associated value as effective bioindicators.

Due to the massive increase of urban population, a global target is achieve sustainable cities that are sensitive nature and environmentally just for dwellers. To accomplish this, it important understand responses native nonnative birds, identify environmental variables promote species limit species, how they vary among socioeconomic groups. Although many in Global South exhibit strong social segregation, few studies have investigated relationship between socioeconomics biodiversity. Therefore, help ecological justice biodiversity conservation developing world, we influence level woody cover on bird richness abundance city Santiago de Chile. We also whether response changes with provenance-it birds separately from because imply opposite management strategies (e.g., vs. control/eradication). Thus, surveyed 120 sites located residential areas high, medium, low levels across fit generalized linear (mixed) models described total, native, according vegetation cover. found both influenced community, but their effects changed origin, having birds.

The globalization of trade and increased human mobility have facilitated the introduction spread nonnative species, posing significant threats to biodiversity well-being. As centers global populations, cities are foci for introduction, establishment, species. We present a synthesis urban characteristics that drive biological invasions within across cities, focusing on four axes: (a) connectivity, (b) physical properties, (c) culture socioeconomics, (d) biogeography climate. Urban such as connectivity among city size age, wealth emerged important drivers species diversity spread, while relative importance biogeographic climate varied considerably. Elaborating how these shape in is crucial designing implementing strategies mitigate impacts ecological systems

Urbanization has drastically transformed natural landscapes, threatening biodiversity by reducing species richness and abundance in cities. In this context, seasonal streams serve as refuge areas for various bird species. To determine the role of conserving native terrestrial avifauna Algarrobo, an expanding urban environment, we compared diversity ephemeral (n = 18) residential 18). Bird counts were conducted during summer winter. We utilized a index Generalized Linear Mixed Models (GLMMs) to assess birds, well six migratory birds. Additionally, accumulation curves verified whether most present had been adequately sampled. Our results revealed that harbored greater than areas. Endemic also recorded these streams. The cumulative number was higher stream environment During winter, birds (Green-backed Firecrown Gray-hooded Sierra Finch) observed These findings suggest play crucial Thus, protecting managing habitats is essential maintaining avian urbanized
