Abstract Alien species often flourish and become invasive in urban ecosystems. How why invaders succeed systems is an important, yet poorly understood, question. We investigate whether the success of related to changes traits that enhance potential. also explore a trophic mechanism helps explain systems. use guppy Poecilia reticulata , globally distributed alien has invaded both non‐urban systems, as our model. first characterize effect urbanization on streams where guppies are present....
ABSTRACT Goldfish Carassius auratus is a longstanding global invader that has entered new phase in its invasion history, spreading into geographical areas and reaching larger body sizes abundances than previously recorded. In this Perspective, we present evidence C. other goldfishes spp. represent an increasing, yet overlooked, risk to North American freshwaters. We synthesize existing knowledge on the physiology, impacts, current management of America. also identify gaps our understanding...
Abstract Stream fishes often display distinct spatial patterns in size distribution, with one possible pattern being larger individuals dominating the headwaters. This “larger fish upstream pattern” (LFUP) has been widely documented, yet ecological drivers remain unclear. We investigated factors contributing to LFUP community of a South American stream. Using historical data (1994–1998) from electrofishing surveys across six sites, we analyzed distribution eight species, predictors including...
Abstract Urban stormwater management ponds (SWMPs) are widely employed for control, but knowledge about their contributions to urban ecosystem function and service delivery remains unclear. We organized a workshop that brought together researchers, managers students assess discuss current information on SWMP services, identify perceived gaps prioritize research needs, advance understanding of SWMPs in Ontario, Canada. Workshop participants identified habitat provisioning regulation water...
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 ecosystems where structure, functioning and dynamics ecosystem are determined by human activities. Despite increasing rates worldwide,the ecology is poorly known. In this chapter, we focus on stream expose current advances fish ecology. We explore topics concerning biodiversity,ecological...
The process of urbanization profoundly changes aquatic ecosystems. Urban streams often have flashier hydrology, increased nutrient and contaminant concentrations, reduced biodiversity when compared with nonurban streams. Collectively, these characteristics are described as the urban stream syndrome (USS). USS is traditionally attributed to discharge large volumes stormwater into streams, thus pointing primary driver degradation. However, was developed using evidence from studies in...
The rapid expansion of urban centers is a critical threat to stream ecosystems, yet we currently lack mechanistic understanding the effects urbanization on communities. Here explore how an intraspecific trait perspective can unveil mechanisms change in Intraspecific approaches are rarely used aquatic ecosystems though their potential has been widely demonstrated terrestrial systems. We begin by identifying several biotic and abiotic agents that drive changes life history, behavior,...
Spatio-temporal changes in the diet, niche breadth and overlap of two species Characidium from three different sites along a Neotropical coastal stream were studied during dry rainy season. Seasonal restricted to occurrence plant items stomach contents. The relative importance food diet both varied across sites, but Diptera, Ephemeroptera, Simuliidae, Trichoptera Coleoptera larvae always main prey items. Contrary expected pattern, values higher at site where co-existed overlapped this...
Abstract Guppies ( Poecilia reticulata ) are frequently introduced to both natural and artificial water bodies as a mosquito control. Laboratory studies have demonstrated that guppies can consume large numbers of larval mosquitoes. Our study investigates how intraspecific variability in guppy phenotype affects their importance biocontrol habitat conditions (natural ponds vs. storage containers) may influence insect biomass feeding. Using blocked experimental design, we established...
Abstract Generalist species dominate urban ecosystems. The success of generalists is often related to a plastic diet and feeding traits that allow them take advantage variety food resources provided by humans in cities. classification as generalist commonly based on mean estimates diet‐ feeding‐related traits. However, there increasing evidence population can consist individual specialists. In such cases, hide important variation explain trophic ecology the dwellers. Here, we focus guppies,...
A pós-graduação no Brasil é historicamente apontada como um espaço de conhecimento dominado por camadas sociais privilegiadas da população, majoritariamente branca, mesmo após a implementação políticas ações afirmativas à nível nacional. O debate sobre diversidade e inclusão na educação superior continua urgente para reduzir desigualdades históricas, além estabelecer práticas institucionais antirracistas. Nesta nota apontamos crescente exigência certificados proficiência em língua inglesa...
We, a group of Brazilian scientists residing abroad in diverse career stages, are writing response to CNPq’s recent announcement the "Talent Repatriation Program - Conhecimento Brasil," (see Morimoto 2024). We discuss our impressions and suggestions align proposal with what program aims achieve.
Abstract Understanding the mechanisms driving parallel evolution across species and populations is fundamental to evolutionary biology. We investigated phenotypic divergence of trophic morphology in response predation pressure two recently described congeneric poeciliid fish, Phalloceros harpagos anisophallos. By comparing from high low environments with similar environmental characteristics, we aimed isolate effect on traits while controlling other sources variation. found that experiencing...
Feeding behaviour and diet of Bryconamericus microcephalus differed between canopy conditions. At the open site, a behavioural modification, grazing on algae, was observed. This also reflected in gut content analysis suggests plasticity response to resource availability.
A alfabetizacao cientifica e vista por muitos autores como ferramenta emancipadora fundamental a cidadania que permite acao critica da sociedade.
