Influence of land use, occupation, and riparian zones on zooplankton diversity in Cerrado streams

Acta Limnologica Brasiliensia (2024)

Gustavo Fernandes Granjeiro Carla Albuquerque de Souza Ruan Carlos Pires Faquim Pedro Paulino Borges Pedro Henrique Francisco de Oliveira

Abstract Aim The riparian zones of the Cerrado biome have decreased significantly due to human expansion, altering the ecological dynamics of ecosystems, and zooplankton can respond to these changes. Therefore, we seek to evaluate the impact of riparian zones and environmental changes on zooplankton communities in streams, considering the trophic state and integrity of riparian zones. The research seeks to determine which predictors play the most significant role in structuring these communities. The main hypothesis is that local factors have a direct influence on zooplankton communities due to nearby limnological conditions. Methods We collected zooplankton samples and physicochemical variables at 20 points located in the Silvânia National Forest and surrounding areas (Goiás, Brazil). A Redundancy Analysis (RDA) was employed after selecting significant variables. A Multivariate Regression Tree (MRT) analysis was used to model relationships between species and environmental characteristics. Results We found that trophic state and forest cover had no significant influence on zooplankton richness and density. Despite identifying 88 species of zooplankton, we did not observe clear relationships with environmental factors. The Multivariate Regression Tree (MRT) analysis, however, revealed distinct clusters, clarifying the factors that shape the zooplankton community. Conclusions Our findings emphasize the need for further investigation into the interaction between zooplankton and their environment to offer valuable insights for ecological management and conservation efforts. Unforeseen disturbances can introduce stochastic elements into community variations, camouflaging the influence of local and spatial factors.

Relative importance of local and landscape variables on fish assemblages in streams of Brazilian savanna

Fisheries Management and Ecology (2019)

Hugo de Oliveira Barbosa Pedro Paulino Borges Renato Bolson Dala‐Corte Patrick Thomaz de Aquino Martins Fabrício Barreto Teresa

Abstract Understanding variability in the composition of aquatic assemblages requires a multiscale perspective, since processes operating at different spatial scales (from regional to local) drive the community assembly. Here, the relative importance of environmental variables on fish species composition in streams of the Brazilian savanna ( Cerrado ) is assessed and quantified at local and landscape scales. The importance of both local and landscape environmental variables in structuring fish assemblages was supported. Local variables explained a substantially higher amount of variance of fish assemblages than landscape variables. However, the shared explanation indicate that landscape variables had a complementary effect. The streams sampled were mostly headwaters at similar altitudes and with similar watershed sizes, so the sensitivity of the fish assemblages, even to small landscape gradients, is highlighted. Maintaining these important instream habitat characteristics close to natural conditions seems to be essential for conserving stream fish species, and for this, the landscape context should be taken into account. Considering the near‐pristine condition of the streams studied, these findings can be used as a reference for further studies addressing the effects of human modifications on stream fish biodiversity of the Cerrado .

Stream fish metacommunity organisation across a Neotropical ecoregion: The role of environment, anthropogenic impact and dispersal-based processes

PLoS ONE (2020)

Pedro Paulino Borges Murilo S. Dias Fernando Rogério Carvalho Lílian Casatti Paulo dos Santos Pompeu

Understanding how assemblages are structured in space and the factors promoting their distributions is one of the main goals in Ecology, however, studies regarding the distribution of organisms at larger scales remain biased towards terrestrial groups. We attempt to understand if the structure of stream fish metacommunities across a Neotropical ecoregion (Upper Paraná—drainage area of 820,000 km2) are affected by environmental variables, describing natural environmental gradient, anthropogenic impacts and spatial predictors. For this, we obtained 586 sampling points of fish assemblages in the ecoregion and data on environmental and spatial predictors that potentially affect fish assemblages. We calculated the local beta diversity (Local Contribution to Beta Diversity, LCBD) and alpha diversity from the species list, to be used as response variables in the partial regression models, while the anthropogenic impacts, environmental gradient and spatial factors were used as predictors. We found a high total beta diversity for the ecoregion (0.41) where the greatest values for each site sampled were located at the edges of the ecoregion, while richer communities were found more centrally. All sets of predictors explained the LCBD and alpha diversity, but the most important was dispersal variables, followed by the natural environmental gradient and anthropogenic impact. However, we found an increase in the models' prediction power through the shared effect. Results suggest that environmental filters (i.e. environmental variables such as climate, hydrology and anthropogenic impact) and dispersal limitation together shape fish assemblages of the Upper Paraná ecoregion, showing the importance of using multiple sets of predictors to understand the processes structuring biodiversity distribution.

SATÉLITE SINO-BRASILEIRO DE RECURSOS TERRESTRES NA LITERATURA CIENTÍFICA GLOBAL: TENDÊNCIAS A PARTIR DE UMA ANÁLISE CIENCIOMÉTRICA

Boletim Goiano de Geografia (2020)

Patrick Thomaz de Aquino Martins Pedro Paulino Borges

Fruto da cooperação entre o Brasil e a China, o CBERS (Satélite Sino-Brasileiro de Recursos Terrestres) é um programa ao desenvolvimento de satélites de sensoriamento remoto o qual tem contribuído ao entendimento de diversos fenômenos e ao gerenciamento territorial. Embora haja produção de conhecimento a partir de dados do programa CBERS, esta ainda não foi caracterizada na literatura científica global. Desse modo, o objetivo do trabalho foi avaliar, por meio de uma análise cienciométrica, as tendências e lacunas dos estudos relacionados ao uso do CBERS. Considerando a base completa da plataforma ISI Web of Knowledge, foram pesquisados manuscritos que utilizaram ou analisaram o CBERS, resultando em 216 artigos, os quais foram examinados com base em 10 diferentes critérios. Foi observado um aumento significativo de artigos ao longo do tempo. O satélite CBERS-2 foi o mais utilizado, com o CCD sendo o mais frequente dentre os todos os sensores. Quando se empregou outro produto de sensoriamento remoto, os satélites do programa Landsat e os das plataformas Aqua e Terra (sensor MODIS) foram os mais observados. Foi identificado um viés relacionado à nacionalidade dos países mantenedores do programa, assim como a prevalência do idioma inglês. O ambiente terrestre foi onde se deu a maior parte dos estudos, ocasionando algumas lacunas a serem exploradas. Além do entendimento de como a comunidade científica internacional vem utilizando o CBERS à geração de conhecimento, a análise cienciométrica identificou o cumprimento do propósito pelo qual o programa foi concebido, a autonomia na geração de dados orbitais.

Transferability of Bioindicators Based on Fish Assemblages to Detect Human Impacts on Stream Ecosystems is Influenced by Spatial Distance and Environmental Differences

SSRN Electronic Journal (2022)

Victoria Sousa Renato Bolson Dala‐Corte Evanilde Benedito Gabriel Lourenço Brejão Fernando Rogério Carvalho

The development of multimetric indices to measure the biotic integrity of aquatic habitats is based on metrics derived from biological assemblages. Considering fish assemblages, the lack of consistency in the metrics’ responses outside the places where they were developed limits the multimetric indices’ transferability and applicability to other locations, requiring local standardization. The factors behind the low transferability of these bioindicators are still poorly understood. We investigated how environmental dissimilarity and spatial distance influence transferability of metrics generated from local stream fish assemblages to other regions. We also tested whether functional and taxonomic metrics respond differently to the spatial distance. We used data from 239 fish assemblages from streams distributed across a Brazilian ecoregion and characterized each site according to the level of anthropogenic disturbance at landscape scale using an Anthropogenic Pressure Index (API). We divided the ecoregion into sub-basins and used two of them to create template response models of the metrics in relation to the API. We used these response models to predict responses outside the template sub-basins. Our response variable representing a metric of transferability was the absolute difference between the metric’s value predicted and the observed metric value for each site. We thus modeled the prediction error in relation to the predictor variables which were i) environmental dissimilarity between each site with the average of the sites from template sub-basins (climatic, topographic and soil type variables) and ii) spatial distance (overland and watercourse distance) between each site and the center of the template sub-basin. We found that errors in metric predictions were associated with both environmental dissimilarity and spatial distance. Furthermore, functional and taxonomic metrics responded equally to spatial distance. These results emphasize the need for local standardization of metrics when developing multimetric indices, especially if protocols already available come from distant and environmentally dissimilar places.

Differential responses of fish assemblages to environmental and spatial factors are mediated by dispersal-related traits in Neotropical streams

Freshwater Science (2022)

Ruan Carlos Pires Faquim Fabrício Barreto Teresa Pedro Paulino Borges Karine Borges Machado João Carlos Nabout

The organization of species metacommunities can be controlled by local factors, such as habitat quality, landscape factors, such as land use, and spatial factors, such as stream network distances. Species within a metacommunity have different traits that may be used to understand the determinants of community structure. This study aimed to understand how changes in environmental and spatial factors affected stream fish assemblages delineated based on their dispersal-related traits, such as preferential habitat use (i.e., benthic, nektobenthic, nektonic, marginal, and surface), preference for water velocity (i.e., fast, intermediate, and slow), and body size (i.e., small, medium, and large). We sampled 18 stream reaches in a dendritic network in the Upper Paraná River basin, located in the Brazilian Cerrado biome. We used variation partitioning techniques to test the relative effects of local environmental, landscape, and spatial variables on different species groups defined according to dispersal-related traits. Environmental and spatial variables weakly explained the variation in total assemblage taxonomic composition. However, based on different functional trait groups, we found that the environment had a strong relationship with assemblage composition of nektobenthic and small fish, whereas spatial variables were most strongly associated with marginal and surface fish. Large-scale spatial variables were associated with large fish and those that prefer slow water, whereas fine-scale variables were associated with small and surface-dwelling fish. These findings help improve understanding of how functional composition of stream fish assemblages may be affected by urban development, riparian conversion, and resulting changes in local environmental conditions.

NEOTROPICAL FRESHWATER FISHES: A dataset of occurrence and abundance of freshwater fishes in the Neotropics

Ecology (2022)

Lívia Helena Tonella Renata Ruaro Vanessa S. Daga Diego Azevedo Zoccal Garcia Oscar Barroso Vitorino

The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large-scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications.

Tendências e lacunas da literatura científica sobre o bioma Cerrado: uma análise cienciométrica

Neotropical Biology and Conservation (2014)

Pedro Paulino Borges Katia Aline Forville de Andrade Oliveira Karine Borges Machado Úrsula Lopes Vaz Hélida Ferreira da Cunha

O Cerrado (Savana brasileira) e o segundo maior bioma brasileiro, sendo considerado um hotspot de biodiversidade, pois apresenta elevado endemismo e esta sob intensa ameaca. O objetivo deste trabalho foi destacar as tendencias das publicacoes sobre o Cerrado, detectar possiveis lacunas e indicar direcoes futuras para trabalhos cientificos nesse bioma. Foi realizada uma busca de artigos utilizando-se a base de periodicos do Institute for Scientific Information (ISI), entre os anos de 1991 a 2012. Foi observado um aumento significativo de artigos ao longo dos anos (r=0,89; P<0,001), demonstrando aumento de interesse da comunidade cientifica sobre o Cerrado. Grande parte dos trabalhos aborda assuntos relacionados a biodiversidade (64,75%), seguida do meio abiotico (13,38%) e de culturas agricolas (11,21%). Alem disso, 10,65% desses trabalhos abordam os temas biodiversidade e meio abiotico conjuntamente. O grupo taxonomico mais estudado foi o das plantas (42%), seguido de fungos (18%) e insetos (12%). Os peixes apresentaram um menor numero de estudos (0,6%). As principais lacunas detectadas estiveram relacionadas a aspectos abioticos e organismos limnicos, como, por exemplo, peixes, bem como um baixo incremento no numero de artigos enfocando invertebrados, excetuando-se os insetos. Assim, sugere-se que futuros estudos sejam direcionados principalmente aos ecossistemas aquaticos e sua biodiversidade. Palavras-chave: biodiversidade, cienciometria, hotspot.
