“…A segregation of families occurred among the sampling sites near the floodplain and those located in the upper reaches of the basin, mainly for families that have migratory representatives. This fact has been observed in previous studies, demonstrating a differentiation in the choice of habitats between the reproductive guilds of the species and the consequent structuring of β diversity (Rosa et al ., 2022; Silva et al ., 2017). The behaviour of migratory species may differ between populations, with populations clustered over time (Ribolli et al ., 2017).…”

“…This reinforces the importance of free‐flowing rivers for the reproduction of migratory species that are of high value for fishing, ecotourism and sport fishing. In addition, it is essential to preserve the environments that are often used for spawning and nursery areas regardless of the fish reproductive strategy for the sustainability of fish stocks (Rosa et al ., 2022).…”

“…In addition to the aforementioned issue, the dendritic structure of river networks determines patterns of diversity (Altermatt, 2013). For Neotropical fish, it has been shown that patterns of variation in assemblage composition are explained by spatial factors (Rosa et al ., 2022; Silva et al ., 2017; Vitorino Júnior et al ., 2016), as well as spatial connectivity (Peláez & Pavanelli, 2019; Sharma et al ., 2011), providing an understanding of different aspects of the diversity of fish assemblages (Peláez & Pavanelli, 2019). In this context, considering river connectivity as a structuring factor for the pattern of variation in the composition of the fish egg and larvae assemblage may provide new insights due to its drift dispersion nature (Lechner et al ., 2016) and influence by physical characteristics of the hydrological system.…”

Reproduction is one of the most important biological aspects for the maintenance of viable populations, and understanding the spatial and seasonal patterns in the reproduction of Neotropical fish is a point that still needs considerable investigation. In this study, the main aim was to reduce knowledge gaps concerning fish eggs and larvae distribution patterns. Therefore, the River Araguaia basin, one of the main hydrographic basins of the Neotropical savanna, was used as the focal point of study. Samplings of fish eggs and larvae were carried across the hydrological regime during flooding and drought events between December 2018 and July 2020 at 15 sites distributed along a 350 km stretch of the River Araguaia basin. Fish eggs and larvae were found in all sampling sites, with the highest number of catches in the flood season. The fish larvae were represented by 5 orders, 22 families and 22 at the genus or species level. Both environments, tributary and main channel of the River Araguaia, are important for fish reproduction, and no difference was found in the use between the main channel and the tributaries. The results showed that spatial factors are important to explain the change in larval composition, which may have a wide or restricted distribution related to specific habitats. The main factors related to the reproductive activity of fish in this region are the physical and chemical changes in the water that occur in the flood season. These results indicate that the River Araguaia basin has environmental integrity and provides favourable conditions for the reproductive activity of fish, including long‐distance migratory species. Considering this, mitigate measures that guarantee the preservation of the natural flow are crucial for the maintenance of fish biodiversity.

Examining paleobotanical databases: Revisiting trends in angiosperm folivory and unlocking the paleoecological promise of propensity score matching and specification curve analysis

Paleobotany is at a crossroads. Long-term trends in the fossil record of plants, encompassing their interactions with herbivores and with the environment, are of the utmost relevance for predicting global change as pCO2 continues to rise. Large data compilations with the potential to elucidate those trends are increasingly easy to assemble and access. However, in contrast to modern ecology and unlike various other paleontological disciplines, paleobotany has a limited history of “big data” meta-analyses. Debates about how much data are needed to address particular questions, and about how to control for potential confounding variables, have not examined paleobotanical data. Here I demonstrate the importance of analytical best practices by applying them to a recent meta-analysis of fossil angiosperms. Two notable analytical methods discussed here are propensity score matching and specification curve analysis. The former has been used in the biomedical and behavioral sciences for decades; the latter is a more recent method of examining relationships between, and inherent biases among, models. Propensity score matching allows one to account for potential confounding variables in observational studies, and more fundamentally, provides a way to quantify whether it is possible to account for them. Specification curve analysis provides the opportunity to examine patterns across a variety of schemes for partitioning data—for example, whether fossil assemblages are binned temporally by stage, epoch, or period. To my knowledge, neither of these methods has been used previously in paleontology, however, their use permits more robust analysis of paleoecological datasets. In the example provided here, propensity score matching is used to separate latitudinal trends from differences in age, climate, and plant community composition. Specification curve analysis is used to examine the robustness of apparent latitudinal trends to the schema used for assigning fossil assemblages to latitudinal bins. These analytical methods have the potential to further unlock the promise of the plant fossil record for elucidating long-term ecological and evolutionary change.
