TL;DR: A multigenerational approach was taken in which survival, reproduction, respiration, growth, brood size, and biomass of Ceriodaphnia dubia were assessed at sublethal concentrations over the course of three successive generations, and it is unlikely that CBZ poses a substantial risk to the environment regarding the end points measured.

TL;DR: The impact of plant toxicity on the dynamics of a plant-herbivore interaction, such as that of a mammalian browser and its plant forage species, is explored by studying a mathematical model that includes a toxin-determined functional response.

TL;DR: In this article, the authors examined the use of resighting data to estimate the rate of population growth for the snail kite population in Florida from 1997-2000, using a robust design approach that derives an estimate of u from estimates of population size and a Pradel (1996) temporal symmetry (TSM) approach that directly estimates u using an open-population capture-recapture model.

TL;DR: Endpoints measured in this study demonstrate that chronic exposure of C. dubia to sertraline leads to effects that occur at concentrations only an order of magnitude higher than predicted environmental concentrations, and that multigenerational effects should be considered in chronic exposure studies because standard toxicity tests do not account for increases in sensitivity in successive generations to toxicants.

TL;DR: The time-scale dependent approach is important because it emphasizes how local (transient) solutions may be more ecologically relevant to stability calculations than overall (global) solutions.
