Invasive predators pose a critical threat to native taxa. Body size plays an important role in mediating the interactions of predator and prey. For piscivorous fishes, increased predator body size can be accompanied by the selection of increasingly ...

ABSTRACT Florida's regulatory framework requires the establishment of minimum flows to protect aquatic ecosystems and water resources from significant harm. One of the primary methods used to evaluate significant harm is assessment of instream habitat, which relies on Habitat Suitability Criteria (HSC) curves that relate flow regimes and habitat ...

Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

Studying the Relationship Between Morphological Characteristics and Ecological Niche Overlap of the Namak Chub (Squalius namak) In the Jajroud River [PDF]
Introduction: The degree of overlap in ecological niches can indicate the extent of resource sharing and potential interspecific competition. The intensity or effects of resource sharing and competition may also be partially related to species abundance,
