Habitat complexity describes a wide array of spatial distribution patterns of physical
structures in habitats. It affects aquatic ecosystems on multiple levels from individuals (eg …

We investigated whether isotopic niche partitioning could mediate the coexistence between
native (Hoplias sp. B) and non‐native (Hoplias mbigua) trahira in a Neotropical floodplain …

Ontogenetic shifts in food preference reduces intraspecific competition as immature
individuals eat different food types than adults. This diet plasticity could facilitate species' …

A bstract Prey fish species can respond to the presence of predators using a variety of
antipredatory behaviors to reduce their risk of being consumed. As such behaviors may also …

ABSTRACT The cichlid Astronotus crassipinnis (Heckel, 1840) known as “oscar” or “apaiari”
is native to the Amazon basin and presents an omnivorous feeding habit, with a tendency to …

Trophic interaction in tropical regions is influenced by factors such as the size of organisms
and the presence of intermediate predators. Macrophytes can act directly on predator–prey …

The understanding of factors affecting resource uptake is important to elucidate community
dynamics in aquatic ecosystems. Here, we analyzed nutrient–phytoplankton and …

We tested whether changes in water transparency caused either by precipitation-mediated
sedimentation (inorganic turbidity) or eutrophication (organic turbidity) differently interact …

In 2017, the International Conference for Aquatic Invasive Species (ICAIS) marked its 20th
anniversary. The conference was hosted in Fort Lauderdale, Florida from Oct 22 to 26, and …

This thesis focuses on the roles habitat complexity and predation play in the structuring of
aquatic communities. Chapter one provides an overview of the way habitat complexity …
