摘要

湿地是具有高度生物多样性的独特生态环境。然而,城市化可能会使这些栖息地退化、消失或改变。尽管两栖动物在城市景观中利用人类创造的栖息地,但很少有研究调查栖息地质量对无尾动物生活史的影响。我们评估了南美普通蟾蜍鼻口长度(SVL)、身体状况和生殖投资等生活史特征,以确定城市化对该物种是有害还是有益。我们对阿根廷Córdoba Cuarto市Río不同城市化水平的湿地进行了采样。我们记录了中等城市化湿地中SVL较低的男性,以及低和高城市化类别中SVL最高的男性,这与身体状况较低的男性居住在中等城市化程度的湿地中的情况相似。在女性中,中等城市化的SVL较低,高城市化和低城市化的SVL最高。我们观察到,在高度城市化的湿地中,雌性的身体状况很低。繁殖投资参数差异不显著,但在城市化程度较低的湿地,产卵数和窝卵数较多。这些结果表明,沙豆对城市化的响应具有可变性,这可能是由于其生活史参数的表型可塑性,使其能够居住在城市地区。需要对这些湿地中的物种进行持续监测,以确定这些生物反应是暂时的还是持久的。

Anuran responses to urbanization: evaluating life history traits of Rhinella arenarum in urban wetlands.

Wetlands are unique ecological environments capable of harboring high biodiversity. However, urbanization can degrade, eliminate, or transform these habitats. Although amphibians utilize habitats created by humans in urban landscapes, few studies have investigated the influence of the habitat quality on the life history of anurans. We assessed life history traits such as snout-vent length (SVL), body condition, and reproductive investment in the South American common toad Rhinella arenarum, to determine whether urbanization is harmful or beneficial to this species. We sampled wetlands with different levels of urbanization in Río Cuarto city, Córdoba, Argentina. We recorded males with lower SVL in medium urbanized wetlands and those with the highest SVL in both low and high urbanization categories, similar to what was found for body conditions with males with low body conditions inhabiting wetlands with a medium degree of urbanization. In females, lower SVL was recorded in medium urbanization and highest SVL in high and low urbanization. It is observed that females recorded in highly urbanized wetlands have a very low body condition. The reproductive investment parameters were not significantly different, but we observed an association between a greater number of eggs and clutch size with wetlands of low urbanization. These results show a variability of responses of R. arenarum to urbanization, which could be due to phenotypic plasticity in its life history parameters, allowing it to inhabit urban areas. Continuous monitoring of the species in these wetlands is needed to determine if these biological responses are temporary or persistent.
