Temperature-Dependent Growth of Brook TroutThe growth of brook trout is closely influenced by water temperature. Experimental data demonstrate how trout weight changes over a 24-day period in response to varying water temperatures. At lower temperatures, such as 15.5 degrees Celsius, brook trout show significant weight gain. However, as the temperature increases, the amount of weight gained steadily decreases. At the highest temperature measured, 24.4 degrees Celsius, trout experience a net...

Background and Environment Affect Phenotype

7.9K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Summary

Rising water temperatures worsen the impact of per- and polyfluoroalkyl substances (PFAS) on fish. Increased temperatures alter PFAS levels in fish tissues, affecting their metabolism and potentially harming offspring development.

Area of Science:

  • Environmental toxicology
  • Aquatic ecophysiology
  • Climate change impacts

Background:

  • Aquatic ecosystems face combined stressors from climate warming and chemical pollution.
  • The physiological impacts of these combined stressors, particularly per- and polyfluoroalkyl substances (PFAS) and temperature, are not fully understood.

Purpose of the Study:

  • To investigate how projected increases in mean summer water temperature affect PFAS toxicokinetics and physiological performance in sheepshead minnows (Cyprinodon variegatus).
  • To assess the combined effects of temperature and PFAS exposure on fish metabolism, swimming, reproduction, and somatic indices.

Main Methods:

  • Adult sheepshead minnows were exposed to an environmentally relevant PFAS mixture (PFOS + PFOA) under current (26 °C) and projected (28.5 °C) mean summer temperatures.
  • Measurements included tissue PFAS concentrations, standard metabolic rate (SMR), maximum metabolic rate (MMR), aerobic scope (AS), swimming performance, reproductive output, and somatic indices.

Main Results:

  • Temperature altered PFAS tissue concentrations, with PFOA notably redistributing to eggs at higher temperatures.
  • Metabolic responses were temperature-dependent: at 26 °C, elevated PFAS correlated with higher SMR and MMR; at 28.5 °C, rising PFAS reduced MMR and AS.
  • While swimming and reproduction showed no significant changes, increased hepatosomatic index and altered PFAS distribution suggested detoxification costs.

Conclusions:

  • Projected increases in mean water temperature are likely to exacerbate contaminant stress from PFAS in aquatic organisms.
  • These findings highlight the need to consider co-stressors like temperature in PFAS risk assessments for coastal fish populations.
  • Warming temperatures may negatively impact fish population resilience and the developmental success of offspring due to increased contaminant stress.
