“…It is not well understood why some species are able to adapt to urban living and others perish (Karr 1981;Marques et al 2019;Santangelo et al 2018;Shochat et al 2006;Walsh et al 2005;Wang et al 2001). Studying two tolerant fish species with differing reproductive strategies (i.e., live-bearing and egg-laying), we found that they both exhibited differences in their GC profiles across the urbanization gradient, and that these differences were associated with differences in life-history traits that are major constituents of fitness.…”

As environments become urbanized, tolerant species become more prevalent. The physiological, behavioral and life-history mechanisms associated with the success of such species in urbanized habitats are not well understood, especially in freshwater ecosystems. Here we examined the glucocorticoid (GC) profiles, life-history traits, and behavior of two species of fish across a gradient of urbanization to understand coping capacity and associated trade-offs. We studied the tolerant live-bearing Western Mosquitofish (Gambusia affinis) for two years and the slightly less tolerant, egg-laying, Blacktail Shiner (Cyprinella venusta) for one year. We used a water-borne hormone method to examine baseline, stress-induced, and recovery cortisol release rates across six streams with differing degrees of urbanization. We also measured life-history traits related to reproduction, and for G. affinis, we measured shoaling behavior and individual activity in a novel arena. Both species showed a trend for reduced stress responsiveness in more urbanized streams, accompanied by higher reproductive output. Although not all populations fit this trend, these results suggest that GC suppression may be adaptive for coping with urban habitats. In G. affinis, GC recovery increased with urbanization, and individuals with the lowest stress response and highest recovery had the greatest reproductive allotment, suggesting that rapid return to baseline GC levels is also an important coping mechanism. In G. affinis, urban populations showed altered life-history trade-offs whereas behavioral traits did not vary systematically with urbanization. Thus, these tolerant species of fish may cope with anthropogenically modified streams by altering their GC profiles and life-history trade-offs. These results contribute to understanding the mechanisms driving species-specific adaptations and thereby community structure in freshwater systems associated with land-use converted areas.

“…A biodiversidade tem sido o principal foco dos estudos ecológicos em ambientes urbanos, incluindo os riachos (McDonnell & Hahs 2013, Marques et al 2019. Diferentes componentes da biodiversidade (riqueza taxonômica, abundância, diversidade filogenética e funcional) vem sendo aplicados nos estudos recentes e as evidências indicam uma profunda alteração na biodiversidade em ecossistemas urbanos (Faeth et al 2011), especialmente devido ao aumento da extinção local e introdução de espécies (Shochat et al 2010).…”

“…Os mecanismos que determinam a evolução e feedbacks eco-evolutivos nas cidades ainda são pouco conhecidos (Alberti 2015, Alberti et al 2017b. Para a biota de riacho, incluindo os peixes, relacionar cada um dos componentes da SRU à mudanças específicas das características fenotípicas, pode permitir entender os mecanismos de adaptação e ajudar a propor feedbacks ecoevolutivos (Marques et al 2019). Entender a evolução contemporânea em ambientes urbanos é fundamental para o desenvolvimento da ciência da biologia evolutiva e promover o entendimento das taxas, direção e repetibilidade da adaptação dos peixes em sistemas urbanos e não-urbanos (Donihue & Lambert 2015).…”

The development of agriculture allowed humans to congregate in settlements which developed into the modern urban societies. This urbanization process caused profound habitat changes, giving rise to urban ecosystems where the structure, functioning and the dynamics of the ecosystem are determined by human activities. Despite the increasing rates of urbanization worldwide,the ecology of urban ecosystems is poorly known. In this chapter, we focus on urban stream ecosystems to expose the current advances in urban fish ecology. We explore topics concerning urban fish biodiversity,ecological interactions and adaptation to urban systems. We also explore different approaches and methodologies for the study of urban fish. Our goal is to introduce the theoretical background and analytical tools to study urban fishes with the intent of facilitating future research

“…Such information is central to understanding how human disturbances, such as urbanization, modulate the strength and direction of sexual selection. This is especially important in aquatic urban ecosystems, such as urban streams, which are much less studied than terrestrial urban systems (Marques et al, 2019;Langerhans and Kern, 2020).…”

Urbanization transforms natural and agricultural areas into built landscapes. Such profound habitat alteration imposes strong pressure on phenotypic trait changes through processes related to natural and/or sexual selection. Evidence of how natural selection drives changes to traits in urban biota is increasing, but little is known about the role of sexual selection. In this study, we assessed the effect of urbanization on the expression and interaction of males' pre-mating traits (body size and color) and a post-mating trait (sperm load). We used a widespread invasive species, the guppy (Poecilia reticulata), which is a wellknown model for studying sexual selection, but have never been studied in urban systems for this purpose. We found that urbanization did not affect mean body size or condition, but it resulted in size-dependent reductions in the expression of orange and iridescent colors, as well as sperm load. The orange color was reduced in small urban guppies, while the iridescent colors were reduced in large urban guppies compared to non-urban guppies. The difference in sperm load was only found in large males, with lower sperm load in urban guppies. The relationship between orange color and sperm load was positive in urban guppies but negative in non-urban guppies, while the association between iridescent color and sperm load followed the opposite pattern. Our findings suggest that sexual selection on pre- and post-mating traits is weaker in urban than in non-urban systems and that interactions between such traits are context dependent. These responses can be related to the pollution and altered visual environment of urban systems and provide an opportunity to advance our understanding of the mechanisms determining adaptation in cities.
