Drivers of phylogenetic structure in Amazonian freshwater fish assemblages [PDF]
Journal of Biogeography, 2021 ABSTRACT Aim Community phylogenetics provides important information about the evolutionary and ecological factors help structure regional species assemblages. Here, we analyze phylogenetic diversity (phylodiversity) patterns among fish species in 97 sub-drainages of the Amazon basin, to evaluate the ...

Principal coordinates analysis of fish assemblage structure based on biomass (g m-2).
, 2022 Data were 4th root-transformed prior to analyses. Vectors are the relative contribution and direction of influence of taxa to the observed variation among sites (Pearson product-moment correlations ≥ 0.5). A.

Diversity, 2021 In this work, the consequences of a local gorgonian coral mortality on the whole coralligenous assemblage were studied. A Before/After-Control/Impact sampling design was used: the structure of the coralligenous assemblage was compared before and after ...

Variation in patterns of fish assemblage and their environmental correlates in a tropical river basin from the Gulf of Mexico slope [PDF]
Neotropical Ichthyology, 2023 Understanding patterns of freshwater fish assemblage structure is key to protect them from ongoing human-induced threats to aquatic biodiversity. Yet, studies on associations between fish assemblages and habitat are lacking from many areas of high ...

Role of Phylogenetic Structure in the Dynamics of Coastal Viral Assemblages [PDF]
Applied and Environmental Microbiology, 2021 Viruses are major agents of microbial mortality in marine systems, yet little is known about changes in the composition of viral assemblages in relation to those of the microbial communities that they infect. Here, we sampled coastal seawater every 2 weeks for 1 year and used high-throughput sequencing of marker genes to follow changes in the ...

Interspecific conflict structures urban avian assemblages [PDF]
Proceedings of the National Academy of Sciences, 2018 Land cover change, of which urbanization is a major driver, remains the greatest threat to terrestrial biodiversity. More than half of all people now live in cities spread across 3% of the global terrestrial surface, and this population is predicted to rise to 68% by 2050 (1).

Climatic seasonality, hydrological variability, and geomorphology shape fish assemblage structure in a subtropical floodplain [PDF]
, 2017 We applied a multiscale approach to understand the patterns of longitudinal, lateral, and temporal variability in fish assemblage structure of a large floodplain river and explored their relationships with climatic seasonality, hydrological variability ...

Knowledge and Management of Aquatic Ecosystems, 2017 Coastal streams provide important habitat for many diadromous fish species, which migrate between freshwater and the sea during their life cycle. However, coastal systems are poorly studied in comparison to large, continental river systems.
