Abstract

Urban environments have been characterized by their temporal stability of resources, which could promote stability in bird composition. Several studies have found that bird communities in urban environments persist over the years, showing a similar species composition in the short term. However, studies analyzing continuous changes in urban communities over the long term are scarce. This study aimed to analyze the stability or directional changes (instability) in bird communities along an urban gradient. Bird counts were conducted in urban, suburban, and periurban areas over 8-10 years in 2002-2019. Changes in species composition were analyzed over periods ranging from one year to the next, to changes from one year to the seventeenth. Urban bird communities were more similar between years than suburban and periurban communities. Compositional changes were greater as time lags increased, indicating directional compositional shifts. The magnitude of these changes was similar across the urban gradient. The Chimango Caracara (Milvago chimango), the Picazuro Pigeon (Patagioenas picazuro), the Rufous Hornero (Furnarius rufus), and the Red-bellied Thrush (Turdus rufiventris) significantly increased their abundances during the period, while the House Sparrow (Passer domesticus) significantly decreased its abundance. Regional changes in species abundance, urban vegetation succession, and biotic interactions could explain the changes in bird communities.

阿根廷马德普拉塔市城市鸟类群落的长期定向变化

城市环境的特点是资源的时间稳定性，这可能会促进鸟类组成的稳定性。一些研究发现，城市环境中的鸟类群落会持续多年，在短期内显示出相似的物种组成。然而，分析城市鸟类群落长期持续变化的研究却很少。本研究旨在分析沿城市梯度鸟类群落的稳定性或方向性变化（不稳定性）。在2002-2019年的8-10年间，对城市、郊区和城郊地区进行了鸟类计数。分析了不同时期物种组成的变化，包括从一年到下一年的变化，以及从一年到第十七年的变化。与郊区和城郊鸟类群落相比，城市鸟类群落在不同年份之间更为相似。随着时间滞后的增加，鸟类组成的变化也越大，这表明鸟类组成发生了方向性变化。这些变化的幅度在整个城市梯度中相似。在此期间，奇曼戈狞鸟（Milvago chimango）、皮卡祖罗鸽（Patagioenas picazuro）、红腹锦鸡（Furnarius rufus）和红腹鸫（Turdus rufiventris）的数量显著增加，而家雀（Passer domesticus）的数量显著减少。物种丰度的区域变化、城市植被演替和生物相互作用可以解释鸟类群落的变化。

期刊介绍： Frontiers in Ecology and Evolution publishes rigorously peer-reviewed research across fundamental and applied sciences, to provide ecological and evolutionary insights into our natural and anthropogenic world, and how it should best be managed. Field Chief Editor Mark A. Elgar at the University of Melbourne is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics and the public worldwide. Eminent biologist and theist Theodosius Dobzhansky’s astute observation that “Nothing in biology makes sense except in the light of evolution” has arguably even broader relevance now than when it was first penned in The American Biology Teacher in 1973. One could similarly argue that not much in evolution makes sense without recourse to ecological concepts: understanding diversity — from microbial adaptations to species assemblages — requires insights from both ecological and evolutionary disciplines. Nowadays, technological developments from other fields allow us to address unprecedented ecological and evolutionary questions of astonishing detail, impressive breadth and compelling inference. The specialty sections of Frontiers in Ecology and Evolution will publish, under a single platform, contemporary, rigorous research, reviews, opinions, and commentaries that cover the spectrum of ecological and evolutionary inquiry, both fundamental and applied. Articles are peer-reviewed according to the Frontiers review guidelines, which evaluate manuscripts on objective editorial criteria. Through this unique, Frontiers platform for open-access publishing and research networking, Frontiers in Ecology and Evolution aims to provide colleagues and the broader community with ecological and evolutionary insights into our natural and anthropogenic world, and how it might best be managed.
