Abstract

We investigated the effects of riparian zones, and associated environmental variables, on the composition and number of species of frogs per sample unit in an Amazonian forest. Sample plots in riparian (up to 10 m from water bodies) and non-riparian areas were distributed over a 25 km(2) sampling grid to obtain a representative sample of habitats in each category. Each plot was sampled three times, over two rainy seasons. The riparian plots harbored more and different species than the non-riparian plots. In riparian areas near streams, the species composition changed along the gradient associated with stream width. The higher number of individuals and species in riparian plots highlights the importance of water courses and associated riparian areas for the conservation of anuran diversity in Amazon rainforests.

Effect of dam on iron species distribution and transformation in riparian zones

Yuxi Lu, Peng Zhang, Hui Liu, Xiaochuang Bu, Yiming Li, Zhang Wen, Minjing Li, Shengjun Mao, Songhu Yuan

Summary: Dams play a significant role in the distribution and transformation of Fe species in riparian zones. This study investigated the impact of a dam on the spatial distribution and seasonal transformation of Fe species in the Han River riparian zone. Results showed that the dam altered the distribution pattern of solid Fe species and influenced the oxidation and reduction processes of Fe. These effects were attributed to variations in sediment lithology and hydrodynamic processes.

Sucessional trajetories of bird assemblages in amazonian secondary forests: Perspectives from complementary biodiversity dimensions

Sergio Henrique Borges, Tarcisio do R. S. Tavares, Nicholas M. A. Crouch, Fabricio Baccaro

Summary: The study found that total species richness and evenness were similar between secondary and old growth forests, but there were more bird species and disturbance-vulnerable species in the controls of old growth forests. Additionally, bird abundance with distinct functional traits differed between secondary forest age categories, and phylogenetic diversity was higher compared to old growth forests, suggesting a positive conservation value of secondary forests for bird diversity.

Summary: It was found that forested buffer zones designed based on varying-depth water table (DTW) index could better protect riparian plant communities, reduce soil erosion, and minimize nutrient leaching in managed forestry areas. This is in contrast to the widely used fixed-width buffer approach, which is adopted due to its simplicity. The cost of DTW-based buffer was also lower than fixed-width buffers, indicating its potential effectiveness and economic benefits.

Understory palms are not canopy palms writ small: Factors affecting Amazonian understory palms within riparian zones and across the landscape

Mariane Guedes, Lourdes Falen, Ocirio S. Pereira, Albertina P. Lima, Carolina V. de Castilho, Rafael F. Jorge, William E. Magnusson, Juliana Hipolito

Summary: The taxonomic composition of understory palms in the Amazon varies mostly in riparian zones, and the abiotic characteristics influencing this variation are not fully explored. This study investigated the relationship between the abundance of understory palms and canopy palms, as well as the effects of topographic and soil variables on the composition of understory-palm assemblages across the entire landscape. The results showed that understory and canopy palms have opposite relationships to environmental variables, and compositional turnover occurs even among sites with subtle environmental differences. Stream discharge and soil structure, impacted by human activities, are among the key factors affecting understory palms in riparian zones.

Nitrogen retention effect of riparian zones in agricultural areas: A meta-analysis

Chunjian Lyu, Xiaojie Li, Peng Yuan, Yonghui Song, Hongjie Gao, Xiaoling Liu, Ruixia Liu, Huibin Yu

Summary: The study systematically reviewed 123 studies on nitrogen removal in riparian zones published between 1980 and 2020. It found that nitrogen reduction showed an exponential decay trend in surface runoff and groundwater, with higher reduction rates at buffer widths of 10-15 meters. Forests had higher nitrogen uptake, denitrification, and N2O emissions efficiency compared to grasslands, and warm weather was beneficial for denitrification and N2O emissions.

Summary: Amazonian floodplain forests along large rivers consist of two distinct floras, which are influenced by different sediment and nutrient environments. Despite the adaptation of tree species to seasonal floods, there are significant differences in ecosystem fertility, disturbance regimes, water shortage and drought, fire, and microclimates between the two ecosystems. These differences largely explain the variations in forest productivity, taxonomic composition, and diversity. Additionally, the two ecosystems track different species life-history traits.

Summary: This study investigated the geographic patterns and ecological correlates of the most common tree dispersal modes in Amazonia, including endozoochory, synzoochory, anemochory, and hydrochory. The results showed that anemochory was positively associated with mean annual wind speed, while hydrochory was higher in flooded forests. The availability of resources for constructing zoochorous fruits did not explain the distribution of dispersal modes. Further research is needed to understand the association between frugivores and the proportional abundance of zoochory.

A matter of size: Does habitat use depend on body size in Amazonian small-stream shrimp species?

Elmo Pereira da Silva, William E. E. Magnusson

Summary: Natural selection plays a crucial role in determining organism size and shape, which in turn affects resource use. Studies have shown that size-specific effects on niche primarily occur in habitat and food dimensions within populations and assemblages. This study investigates the potential impact of body size on habitat selection in freshwater shrimp species, revealing slight habitat segregation among individuals of different sizes but considerable overlap in habitat use. The findings suggest that while there are subtle ontogenetic shifts in habitat use by conspecifics and differences between individuals of different species with similar sizes, size does not play a major role in driving habitat segregation in shrimp populations and assemblages.

Summary: This study evaluated the impact of wetland loss on tropical river banks on small non-flying mammal assemblages. By analyzing data from pre-reservoir filling monitoring in the Brazilian Amazon, it was found that the flooding of low-lying areas did not negatively affect the assemblage of non-flying small mammals in the short term. However, the remaining areas need to be conserved to maintain the importance of the lost areas for population dynamics.

Summary: Amazon forests are experiencing degradation due to various human disturbances, leading to changes in ecosystem and climate function. Through analyzing a large database of canopy lidar data from disturbed and mature forest plots, we found that different land-use and climate-change disturbances have varying impacts on canopy structure. Most disturbed sites showed signs of recovery, but the severity and nature of structural impacts differed among disturbance types. However, there were commonalities in regeneration pathways across disturbance types. The study highlights the resilience of Amazon forests and the importance of studying diverse disturbance types in predicting forest transitions.

Summary: In a rapidly changing global environment, understanding the factors that determine species abundance distribution is crucial for studying ecosystem dynamics. The constrained maximization of information entropy framework allows for quantitative analysis of these complex dynamics by examining important constraints using unbiased probability distributions. By applying this framework to Amazonian tree inventories across various forest types and functional traits, the study demonstrates that regional relative abundances of genera have a greater influence on local relative abundances than directional selection for specific functional traits. These results provide valuable insights into ecological dynamics using large-scale data and interdisciplinary methods.

How environmental factors affect the abundance and distribution of two congeneric species of Amazonian frogs

Eduardo Moreno, Pedro Pequeno, Sergio Santorelli Junior, Miqueias Ferrao, Albertina Pimentel Lima, William E. Magnusson

Summary: This study examines the impact of environmental variables on sister species that live in sympatry and are closely related in terms of phylogeny at a fine-scale level. The findings suggest that these species have distinct environmental associations, which may contribute to their coexistence. One species demonstrates a preference for drier environments, while the other species exhibits a more generalist habitat and resource use. These patterns support the hypothesis that environmental variables influence sister species differently, and the evolution of certain characteristics may reduce competition for resources, facilitating coexistence in sympatry.

Conservation implications of tourism and stress for Amazonian caimans

Washington C. S. Mendonca, Wallice P. Duncan, Marcelo D. Vidal, William E. Magnusson, Ronis Da Silveira

Summary: Ecotourism, while important for biodiversity conservation, may have negative effects on animal health and welfare. A study in Anavilhanas National Park, Brazil revealed that interactions between tourists and Amazonian crocodilians led to increased levels of corticosterone and lactate in black caimans, but not in spectacled caimans. These findings have implications for the management and conservation of Amazonian crocodilians, especially in tourism programs.
