Cardiac and metabolic physiology of early larval zebrafish (Danio rerio) reflects parental swimming stamina

Description: This article explores swimming stamina in fish. Mature adult zebrafish (Danio rerio) were subjected to a swimming performance test and then bred within performance groups to discover if enhanced swimming stamina in offspring appears only in juveniles/adults, or if these traits appear as early as larvae.

In situ cardiac performance of Atlantic cod (Gadus morhua) at cold temperatures: long-term acclimation, acute thermal challenge and the role of adrenaline

Description: This article measures the cardiac performance of Newfoundland Atlantic cod (Gadus morhua). The results: (1) show that maximum performance of the isolated cod heart is not compromised by exposure to cold temperatures; and (2) support data from other studies, which show that, in contrast to salmonids, cod cardiac performance/myocardial contractility is not dependent upon humoral adrenergic stimulation.

Constraints-based stoichiometric analysis of hypoxic stress on steroidogenesis in fathead minnows, Pimephales promelas

Description: This article presents a study in which an in silico genome-scale metabolic model of steroidogenesis is used to investigate the effects of hypoxic stress on steroid hormone productions in fish. This article introduces a powerful model for pathway analysis that can lend insights on the effects of various stressor scenarios on metabolic functions.

Upper lethal temperatures of Northern Bobwhite embryos and the thermal properties of their eggs

Description: This article explores the upper lethal temperature for Bobwhite eggs. Results find that thermal tolerances of Northern Bobwhite embryos are high, indicating an adaptation to the naturally occurring temperature extremes in the Bobwhite's environment. However, the results also indicate that high temperatures could have plausibly contributed to the population decline observed in the Bobwhite's semi-arid range.

Biochemical and molecular-genetic characterization of SFD1’s involvement in lipid metabolism and defense signaling

Description: Article describes study which sought to to determine if the dihydroxyacetone phosphate (DHAP) reductase activity and chloroplast localization are required for the Arabidopsis thaliana SFD1 (suppressor of fatty acid desaturase deficiency1) gene’s involvement in galactolipid metabolism and systemic acquired resistance (SAR) signaling.

Metabolomics as a hypothesis-generating functional genomics tool for the annotation of Arabidopsis thaliana genes of “unknown function”

Description: Article describes the analysis of Arabidopsis metabolomics data sets acquired by a consortium that includes five analytical laboratories, bioinformaticists, and biostatisticians, which aims to develop and validate metabolomics as a hypothesis-generating functional genomics tool.

Effect of selection for commercially productive traits on the plasticity of cardiovascular regulation in chicken breeds during embryonic development

Description: Article investigates basic cardiovascular physiology in the Red Junglefowl, the broiler, and the White Leghorn breeds at 90% of incubation. The authors aimed to identify breed-specific features of arterial blood pressure and heart rate as well as the physiological mechanisms regulating them. They concluded that selection for rapid growth shifts cardiovascular regulatory plasticity to emphasize mechanisms that modulate pressure, and that selection for egg-laying capacity emphasizes mechanisms that modulate heart rate.

Cardiac and metabolic physiology of early larval zebrafish (Danio rerio) reflects parental swimming stamina

Description: Article describes experiment in which mature adult zebrafish (Danio rerio) were subjected to a swimming performance test that allowed separation into low swimming stamina or high swimming stamina groups in order to determine if inherited traits that support enhanced swimming stamina in offspring appear only in juveniles and/or adults, or if these traits actually appear earlier in the morphologically quite different larvae.
