The membrane pacemaker hypothesis: novel tests during the ontogeny of endothermy (open access)

The membrane pacemaker hypothesis: novel tests during the ontogeny of endothermy

Article explores the ‘membrane pacemaker’ hypothesis which proposes a biochemical explanation for among-species variation in resting metabolism, based on the positive correlation between membrane docosahexaenoic acid (DHA) and metabolic rate. The authors tested this hypothesis using a novel model, altricial red-winged blackbird nestlings, predicting that the proportion of DHA in muscle and liver membranes should increase with the increasing metabolic rate of the nestling as it develops endothermy. In support of the membrane pacemaker hypothesis, DHA proportions increased in membranes from pectoralis muscle, muscle mitochondria and liver during post-hatch development. By contrast, elevated dietary DHA had no effect on resting metabolic rate, despite causing significant changes to membrane lipid composition.

Lipoxygenase-mediated Oxidation of Polyunsaturated N-Acylethanolamines in Arabidopsis (open access)

Lipoxygenase-mediated Oxidation of Polyunsaturated N-Acylethanolamines in Arabidopsis

Article hypothesizing that lipoxygenase (LOX) participated in the metabolism of PU-NAEs through the formation of NAE-oxylipins. The data suggests that Arabidopsis LOXs indeed compete with FAAH to metabolize PU-NAEs during seedling establishment. Identification of endogenous amide-conjugated oxylipins suggests potential significance of these metabolites in vivo, and FAAH mutants may offer opportunities to address this in the future.

Altitudinal gradients in Magellanic sub-Antarctic lagoons: the effect of elevation on freshwater macroinvertebrate diversity and distribution (open access)

Altitudinal gradients in Magellanic sub-Antarctic lagoons: the effect of elevation on freshwater macroinvertebrate diversity and distribution

In this article, freshwater macroinvertebrate diversity associated with lakes and ponds along the altitudinal gradient of a Magellanic sub-Antarctic watershed are assessed. A monotonic decline in species richness was observed with increasing elevation, with simpler and more even community composition at higher altitude. This pattern differs from the mid-peak trend found in streams of the same watershed. Functional feeding group structure also diminished with increasing elevation.

Systemic signaling during abiotic stress combination in plants (open access)

Systemic signaling during abiotic stress combination in plants

Article reveals that plants can integrate different local and systemic signals generated during conditions of stress combination. Furthermore, results show that the specific part at which plants sense the two co-occurring stresses makes a significant difference in how fast and efficient they acclimate.

Manipulating plasma thyroid hormone levels alters development of endothermy and ventilation in nestling red-winged blackbirds (open access)

Manipulating plasma thyroid hormone levels alters development of endothermy and ventilation in nestling red-winged blackbirds

Authors of the article propose that thyroid hormones play an important role in regulating development of endothermy during the nestling period in altricial birds. Their data suggests plasma thyroid hormone levels play an active role in the systemic development of endothermic capacity and the development of ventilatory control.
