Cardiac plasticity in fishes: environmental influences and intraspecific differences

Cardiac plasticity in fishes: environmental influences and intraspecific differences.

Fish cardiac physiology and anatomy show a multiplicity of intraspecific modifications when exposed to prolonged changes in environmentally relevant parameters such as temperature, hypoxia and food availability, and when meeting the increased demands associated with training/increased activity and sexual maturation. Further, there is evidence that rearing fish under intensive aquaculture condit...

Gender Differences in Patients' Beliefs About Biological, Environmental, Behavioral, and Psychological Risk Factors in a Cardiac Rehabilitation Program

Introduction: There are significant gender differences in the epidemiology and presentation of cardiovascular diseases (CVDs), physiological aspects of CVDs, response to diagnostic tests or interventions, and prevalence or incidence of the associated risk factors. Considering the independent influence of gender on early dire consequences of such diseases, this study was conducted to investigate...

Environmental Influences on Visual Cortex Development and Plasticity

Environmental influences on cognitive and brain plasticity during aging.

In the current article, we provide a critical review of the extant literature that has focused on environmental influences on cognitive and brain plasticity over the adult life span. The review includes both human epidemiological, and human and nonhuman cross-sectional and longitudinal research. We review a number of factors that have been suggested to reduce age-related cognitive decline inclu...

The evolution of phenotypic plasticity in spatially structured environments: implications of intraspecific competition, plasticity costs and environmental characteristics.

We model the evolution of reaction norms focusing on three aspects: frequency-dependent selection arising from resource competition, maintenance and production costs of phenotypic plasticity, and three characteristics of environmental heterogeneity (frequency of environments, their intrinsic carrying capacity and the sensitivity to phenotypic maladaptation in these environments). We show that (...
