Abstract	Generalist species dominate urban ecosystems. The success of urban generalists is often related to a plastic diet and feeding traits that allow them to take advantage of a variety of food resources provided by humans in cities. The classification of a species as a generalist is commonly based on mean estimates of diet- and feeding-related traits. However, there is increasing evidence that a generalist population can consist of individual specialists. In such cases, estimates based on mean can hide important individual variation that can explain trophic ecology and the success of urban dwellers. Here, we focus on guppies,

Abstract	Parental care is a major feature in the evolution of life‐history traits and appears highly associated with the trade‐off between egg number and size. It has been a controversial issue in studies about reproductive strategy and is deemed to have evolved multiple times, both in aquatic and terrestrial taxa. To explore relationships between parental care and egg size, we examined 313 species of bony fishes, including 152 species with parental care and 161 species without parental care. We mapped parental care onto a maximum likelihood (ML) unrooted phylogeny and analysed egg size and numbers data set using a logistic regression. The phylogenetically controlled analyses revealed that parental care is dispersed along with the retrieved phylogeny and that at least four distinct lineages parallel evolved from non‐parental care lineages to parental care ones. The results of the logistic regression highlighted that egg size can be used as a good predictor of parental care and that there is a strong and consistent threshold in egg size transition between parental and non‐parental care fishes. We conclude that egg size predicts parental care in bony fish and that egg size distribution is polymodal within parental care species probably reflecting the variation in the amount of energy used for care. To advance the knowledge about the hypotheses raised in this study, it would be important to gather information about more species and their respective number and size of eggs and the presence/absence of parental care.

Abstract	We provide length‐weight relationships (LWR) estimates for 45 species from the upper Tocantins River basin. Specimens were sampled by a standardized set of gill nets varying from 15 mm to 150 mm mesh size for 15 years (from 1995 to 2010) of field works. Field expeditions were carried out in three temporal bins with bimonthly samplings, (i) December 1995 to February 2000, (ii) February 2001 to December 2002, and (iii) February 2009 to December 2010, totalizing 46 field works. For all species, standard length (SL; 0.1 cm precision) and total weight (Wt; 0.01 g precision) were determined using a scale and a digital balance, respectively. From these 45 species, 28 have no previous LRW information in Fishbase, and we also provide new maximum standard length for 16 species. When data for at least 10 male or female individuals were available, we also provided the LWR information separately by gender.

Abstract	The removal of native forest affects stream characteristics, processes, and organisms at the local scale. We compared the structure of fish assemblages between microbasins impacted by deforestation and those in pristine condition in the Amazonian Machado River basin, Brazil. Fish were collected with seine and dip nets along an 80-m stretch of 28 streams. At each site, we recorded physical, chemical, and land-water ecotone variables. We collected 6,586 specimens of 109 species, being 39 and 18 of them exclusively of forested and deforested streams, respectively. Non-significant differences were found for abundance and species richness between forested and deforested streams. A total of four main trophic groups were identified. Carnivores were more abundant in forested streams, whereas herbivores, omnivores and detritivores species were the most abundant in deforested streams. The deforested streams showed higher abundance and richness of algae and periphyton consumers, while forested streams presented higher abundance and richness of invertebrate consumers. Forested streams presented longer foodchains, higher occurrence and abundance of species that have more specialized habits and are intolerant to degraded environments, whereas generalist and tolerant species predominated in deforested streams. We conclude that species composition in Amazonian streams predictably responds to the degree of forest cover.

Abstract	The current COVID-19 pandemics is a major threat to human populations. The disease has rapidly spread, causing mass hospitalization and the loss of millions of people mainly in urban areas which are hubs for contagion. At the same time, the social distancing practices required for containing the outbreak have caused an eruption of mental illnesses that include symptoms of depression, anxiety and stress. The severity of such mental distress is modulated by the context of media coverage and the information and guidelines from local health authorities. Different urban green infrastructures, such as gardens, parks, and green views can be important for mitigating mental distress during the pandemics. However, it is unclear whether some urban green infrastructures are more efficient than others in reducing mental distress or whether their effectiveness changes with the context. Here we assess the relative importance of different urban green infrastructures on the mental distress of residents of Rio de Janeiro, Brazil. We show that although urban parks and green views are important, home gardens are the most efficient in mitigating mental distress. This is likely related to the practice of self-isolation seen for the residents of Rio de Janeiro. Information on the efficiency of different urban green infrastructures in mitigating mental distress can be important to help guide programs to inform the public about the best practices for maintaining mental health during the current outbreak. This can also help planning cities that are more resilient to future pandemics.

Abstract	The identification of mechanisms of spatial-temporal variation, obtained from the quantification of natural populations, is a central topic of ecological research. Despite its importance to life-history theory, as well as to conservation and management of natural populations, no studies concerning movement patterns and home range of small stream-dwelling fishes from Brazilian rain forests are known. In the present study we aimed to describe the longitudinal pattern of long distance movement as well as local patterns of short movement (daily home-range) of fishes from a Mata Atlântica stream from Southeast Brazil. We gathered information about movement dynamic in order to discuss the relationship between swimming ability, fish morphology and home range. Long distance movement data were obtained in a mark-recapture experiment held in the field between June and September - 2008, on five sites along the Ubatiba stream. For this study, we had one day to mark fishes, on June-19, and 14 events for recapture. Considering the ten species that inhabit the study area, our study showed that four species: Astyanax janeiroensis, Astyanax hastatus, Parotocinclus maculicauda and Pimelodella lateristriga, moved at least 6 000m in 60 days. The other six species did not present long distance movements, as they were recaptured in the same site 90 days after being marked. For short distance study, movement data were obtained in one mark-recapture experiment held in a 100m long site subdivided into five 20m stretches where fishes were marked with different elastomer colours. We marked 583 specimens that after recapture showed two groups of different movement patterns. The first group was called "Long Movement Group" and the second one was called "Short Movement Group". The Long Movement Group showed, on average, 89.8% of moving fishes and 10.2% of non moving fishes, against 21.3% and 78.7%, respectively, for the Short Movement Group. It was concluded that fish movement could explain the previously mentioned community stability, and that it is correlated to specific morphological attributes.

Abstract	Alien species often flourish and become invasive in urban ecosystems. How and why invaders succeed in urban systems is an important, yet poorly understood, question. We investigate whether the success of urban invaders is related to changes in species traits that enhance invasive potential. We also explore whether a trophic mechanism helps explain the success of invaders in urban systems. We use the guppy Poecilia reticulata, a globally distributed alien species that has invaded both urban and non‐urban systems, as our model. We first characterize the effect of urbanization on streams where guppies are present. We measure guppy invasion success using their population density and size‐frequency. Then we assess how traits that are related to the potential of guppies to invade (life history and condition) respond to urbanization. Next, we explore how urbanization affects the availability of food for guppies and their diets. We also test if the presence of other fish species grants biological resistance to invasion by dampening guppy invasive potential. We find that urban streams have high concentrations of ammonium and faecal coliforms, indicating contamination from sewage. On average, guppy populations from urban streams have 26× higher density and larger body sizes than non‐urban populations. Urban guppies are in better condition and have on average five more offspring than non‐urban guppies. Urbanization increases the availability and consumption of highly nutritious food (chironomid larvae) by guppies. We find a positive relationship between the consumption of chironomids and both fecundity and condition. The presence of other fish species in urban streams often has a negative but small effect on guppy traits and density. Our data suggest a relaxation of trade‐offs that shape life‐history traits which is related to increased food resources in urban streams. These indicate that urbanization enhances the invasive potential of guppies through a trophic mechanism that simultaneously increases reproduction and somatic investment. Such mechanism is likely widespread because chironomids are often highly abundant in urban systems. Thus, not only guppies but also other invasive species can take advantage of such a resource to invest in traits that enhance invasion success.

Abstract	Life history traits of Phalloceros anisophallos from Córrego Andorinha, Ilha Grande (RJ, Brazil) were examined and the following parameters were evaluated: superfetation, matrotrophy, brood size, reproductive season, length–weight relationship, female weight and brood size relationship. Males were smaller and less abundant than females. According to the temporal variation of the gonadosomatic index, reproduction occurred throughout the year, with a reduction around April. We did not register superfetation among reproductive females, but there was significant increase of dry weight of developing embryos, indicating substantial matrotrophy. Such a combination of reproductive features seems to be rare in the family Poeciliidae but common in the genus Phalloceros . More studies on the other species of the genus are necessary to confirm this pattern.
