Agasild H, Cremona F, Tuvikene A, Val A, Panksep K, Zingel P
J Fish Biol
. 2025 Feb;
PMID: 39936372
Amazonian floodplain lakes, distinguished by their water types, are crucial ecosystems for fish biodiversity. In these ecosystems, the annual hydrological cycle, known as the "flood pulse," is the primary driving...

Braz-Mota S, Ollerhead K, Lamarre S, Almeida-Val V, Val A, MacCormack T
J Exp Biol
. 2024 Sep;
227(21).
PMID: 39319428
The Arctic is warming three times faster than the global average, imposing challenges to cold-adapted fish, such as Arctic char (Salvelinus alpinus). We evaluated stress and metabolic responses of Arctic...

Gonzalez R, Patrick M, Val A
J Comp Physiol B
. 2024 Apr;
194(5):685-696.
PMID: 38652292
The first studies on ion regulation in fish exposed to low pH, which were inspired by the Acid Rain environmental crisis, seemed to indicate that ion transport at the gills...

Portner H, Scholes R, Arneth A, Barnes D, Burrows M, Diamond S, et al.
Science
. 2023 Apr;
380(6642):eabl4881.
PMID: 37079687
Earth's biodiversity and human societies face pollution, overconsumption of natural resources, urbanization, demographic shifts, social and economic inequalities, and habitat loss, many of which are exacerbated by climate change. Here,...

Shartau R, Harter T, Baker D, Aboagye D, Allen P, Val A, et al.
Comp Biochem Physiol A Mol Integr Physiol
. 2022 Sep;
274:111304.
PMID: 36049728
High CO (hypercapnia) can impose significant physiological challenges associated with acid-base regulation in fishes, impairing whole animal performance and survival. Unlike other environmental conditions such as temperature and O, the...

Exposure to pH 3.5 water has no effect on the gills of the Amazonian tambaqui (Colossoma macropomum)
Gonzalez R, Patrick M, Duarte R, Casciato A, Thackeray J, Day N, et al.
J Comp Physiol B
. 2021 Feb;
191(3):493-502.
PMID: 33598785
Tambaqui (Colossoma macropomum) are a model species for tropical fish physiology, but details are lacking about their ionoregulatory response to acid waters. To provide specifics, we measured unidirectional Na fluxes...

Ruiz-Jarabo I, Amanajas R, Baldisserotto B, Mancera J, Val A
Comp Biochem Physiol A Mol Integr Physiol
. 2020 Apr;
245:110706.
PMID: 32304738
Stress responses in teleosts include the release of hormones into the bloodstream. Their effects depend on the species and on the environmental conditions. The Amazon basin collects waters of diverse...

Shartau R, Baker D, Harter T, Aboagye D, Allen P, Val A, et al.
J Exp Biol
. 2020 Mar;
223(Pt 7).
PMID: 32127382
Acute (<96 h) exposure to elevated environmental CO (hypercarbia) induces a pH disturbance in fishes that is often compensated by concurrent recovery of intracellular and extracellular pH (pH and pH,...

Campos D, Val A, Almeida-Val V
J Therm Biol
. 2018 Mar;
72:148-154.
PMID: 29496008
The metabolism of fishes is profoundly affected by environmental factors such as temperature, oxygen concentration, and pH levels. Also, biotic elements, for instance, activity levels of species, have been suggested...

Cassidy A, Driedzic W, Campos D, Heinrichs-Caldas W, Almeida-Val V, Val A, et al.
J Exp Biol
. 2017 Dec;
221(Pt 2).
PMID: 29212844
The Amazonian cichlid is highly tolerant to hypoxia, and is known to reduce its metabolic rate by reducing the activity of energetically expensive metabolic processes when oxygen is lacking in...
