Fish die-off in river and reservoir: A review on anoxia and gas supersaturation
Neotropical Ichthyology, 2021 Albeit massive fish mortality has an extraordinary visual impact and is certainly a fatality, we still have rudimentary understanding on how addressing this problem in the Neotropical region. The processes that lead to fish die-off events are complex and

Phagocytotic activity and gene expression of leukocytes isolated from Astyanax lacustris
Brazilian Journal of Biology, 2023 The constant intensification of aquaculture has considerable increased the stress levels of farmed fish and, consequently, the number and intensity of diseases outbreaks. Thus, studies on fish immune response, especially regarding the interaction of fish

CRATER LAKE COLONIZATION BY NEOTROPICAL CICHLID FISHES [PDF]
Evolution, 2012 Volcanic crater lakes are isolated habitats that are particularly well suited to investigating ecological and evolutionary divergence and modes of speciation. However, the mode, frequency, and timing of colonization of crater lakes have been difficult to determine.

Functional responses to deforestation in fish communities inhabiting neotropical streams and rivers
Ecological Processes, 2023 Background Deforestation is a widespread disturbance for neotropical freshwater ecosystems. While biodiversity declines have been associated with deforestation, its functional consequences for stream and river fish faunas remain poorly understood.
