Abstract

Population response to anthropogenic activities will be influenced by prior adaptation to environmental conditions. We tested how parasite-resistant and -susceptible strains of a freshwater snail responded to cadmium and elevated temperature challenges after having been exposed to low-level cadmium continuously for multiple generations. Snails exposed to cadmium for three generations were removed for the fourth generation, and challenged in the fifth generation with (1) chronic cadmium exposure over the entire life cycle, (2) acute cadmium exposure of adults, and (3) elevated temperature challenge of adults. The parasite susceptible NMRI strain is more cadmium tolerant than the parasite resistant BS90 strain and remained more tolerant than BS90 throughout this study. Additionally, NMRI exhibited greater adaptive capacity for cadmium than BS90 and became more tolerant of both chronic and acute cadmium challenges, while BS90 became more tolerant of acute cadmium challenge only. Fitness costs, reflected in population growth rate, were not apparent in fifth generation snails maintained in cadmium-free conditions. However, costs were latent and expressed as decreased tolerance to a secondarily imposed temperature stress. Adaptation to prior selection pressures can influence subsequent adaptation to anthropogenic stresses and may have associated costs that reduce fitness in novel environments.

Demographic responses to multi-generation cadmium exposure in two strains of the freshwater gastropod, Biomphalaria glabrata.

Journal Article Salice, Christopher; Miller, Thomas; Roesijadi, Guritno - Archives of Environmental Contamination and Toxicology

A life table response experiment (LTRE) was used to quantify the population-level effects of continuous, multi-generation cadmium exposure on two strains of the freshwater gastropod, Biomphalaria glabrata; the parasite resistant BS90 and parasite susceptible NMRI strains. Snails were exposed to waterborne cadmium for three consecutive generations. Survival, growth and reproduction were measured empirically and incorporated into a stage-based, deterministic population model. Cadmium significantly affected hatching success, time to maturity and juvenile and adult survival in both strains. There were significant effects of generation on fecundity, hatching success time to maturity and juvenile survival in NMRI and time to maturity andmore »« less

Influence of acclimation and exposure temperature on the acute toxicity of cadmium to the freshwater snail Potamopyrgus antipodarum (Hydrobiidae)

Journal Article Moeller, V; Forbes, V; Depledge, M - Environmental Toxicology and Chemistry; (United States)

Forty-eight-hour acute toxicity tests were performed to determine the influence of acclimation temperature (5, 15, and 20 C) and exposure temperature (5, 15, and 20 C) on the toxicity of cadmium to the freshwater gastropod Potamopyrgus antipodarum. Mortality varied with cadmium concentration and treatment conditions, but did not conform to conventional sigmoid concentration-response relationships. Because the shapes of the concentration-response curves were treatment dependent, a nontraditional approach for data analysis was employed. Regardless of acclimation temperature, mortality increased with increasing exposure temperature, and at all exposure temperatures snails acclimated at 15 C were most susceptible to cadmium toxicity.

Petroleum hydrocarbon resistance in the marine worm Neanthes arenaceodentata induced by chronic exposure to No. 2 fuel oil

Journal Article Rossi, S; Anderson, J - Bull. Environ. Contam. Toxicol.; (United States)

Three successive generations of the marine polychaetous annelid Neanthes arenaceodentata taken from a laboratory population, were continuously exposed to one of three sublethal concentrations of No. 2 Fuel Oil water-soluble-fraction (WSFs). During each generation larvae, juvenile, and immature adult polychaetes were challenged with acute (96 h) doses of No. 2 Fuel Oil or south Louisiana crude oil WSF to test their sensitivity to petroleum hydrocarbons (PHCs). Larvae from all 3 generations, at all exposure concentrations, were no different from control (susceptible) larvae in their sensitivity to the two test oils. F1, F2, and F3 adults exhibited equally increased PHC resistancemore »« less

SAS probit analysis for cadmium mortality

Journal Article Morgan, R; Kundomal, Y; Hupp, E - Environ. Res.; (United States)

In the quantitation of heavy metal effectiveness it is useful to compute the median lethal dose (LD/sub 50/) to the exposed population. The computerized Statistical Analysis System (SAS) of probit analysis is particularly useful in analyzing dose-response data because it is more accurate than the graphical methods currently in use and, in addition, provides fiducial limits with its estimates. Acute and chronic cadmium mortalities of yound adult male and female Sprague-Dawley rats were determined by the SAS probit analysis. When male and female rats were administered comparable doses of cadmium chloride, based on individual body weights, males were more susceptible.more »« less

Variation in metal tolerance associated with population exposure history in Southern toads (Anaxyrus terrestris)

Journal Article Flynn, R.; Love, Cara; Coleman, Austin; ... - Aquatic Toxicology

Human activities have radically shaped the global landscape, affecting the structure and function of ecosystems. Habitat loss is one of the most visible changes to the landscape and a primary driver of species declines; however, anthropogenic environmental contamination also threatens population persistence, but is not as readily observed. Aquatic organisms are especially susceptible to chemical perturbations, which can negatively impact survival and fitness related traits. Some populations have evolved tolerance to chemical stressors, which could mitigate the consequences associated with contamination. Amphibians are experiencing global declines due to multiple stressors and are particularly at risk to aquatic chemical stressors duemore »« less
