Article asserts that the Magellanic sub-Antarctic Forest is home to the world's southernmost avian community and is the only Southern Hemisphere analogue to Northern Hemisphere temperate forests at this latitude. Authors describe annual survival patterns and their association with climate variables using a 20-year mark–recapture data set of five forest bird species in the Cape Horn Biosphere Reserve.

Article describes how, although pennycress, a winter annual, could be grown as a dedicated bioenergy crop, an increase in its seed oil content is required to improve its economic competitiveness. In this work, the authors combined biomass composition with metabolomic and transcriptomic studies of developing embryos from 22 pennycress natural variants to identify targets for oil improvement.

Article describes how C-lignin is a homopolymer of caffeyl alcohol present in the seed coats of a variety of plant species including vanilla orchid, various cacti, and the ornamental plant Cleome hassleriana. The authors used information from a transcriptomic analysis of developing C. hassleriana seed coats to suggest strategies for engineering C-lignin in a heterologous system, using hairy roots of the model legume Medicago truncatula.

Article describes how non-alcoholic fatty liver disease (NAFLD) is currently plaguing the population at pandemic proportions and is expected to become more prevalent over the next decade. The authors investigated the hypothesis that exposure to a mixture of gasoline and diesel engine emissions (MVE), coupled with the concurrent consumption of a HF diet, promotes the development of a NAFLD phenotype within the liver.

This article proposes an urban nutrition (UN) extension to the previously published urban ecological economic system. The proposed extension can be used by decision makers worldwide to evaluate how landscape configurations and agricultural production systems affect the nutritional needs of the local population while fostering sustainable practices.

Article states that mass-spectrometry-based screening of lipid extracts of wounded and unwounded leaves from a collection of 364 Arabidopsis thaliana T-DNA insertion lines produced lipid profiles that were scored on the number and significance of their differences from the leaf lipid profiles of wild-type plants. The analysis identified Salk_109175C, which displayed alterations in leaf chloroplast glycerolipid composition, including a decreased ratio between two monogalactosyldiacylglycerol (MGDG) molecular species, MGDG(18:3/16:3) and MGDG(18:3/18:3).

Article describes how both biochemically and genetically, that ascorbate (AsA) is an alternative “starter unit” to flavan-3-ol monomers for leucocyanidin-derived (+)-catechin subunit extension in the Arabidopsis thaliana anthocyanidin synthase (ans) mutant. The authors' findings advance the knowledge of (+)-catechin-type PA extension and indicate that PA oligomerization does not necessarily proceed by sequential addition of a single extension unit. AsA-[C]n defines a new type of PA intermediate which we term “sub-PAs”.

This article is a study that represents the first transcriptome analysis of E+ and E− Texoma tall fescue under freezing and chilling temperatures in the natural field environment.

Article states that despite remarkable advances in cancer research, cancer remains one of the leading causes of death worldwide. The author's proposed framework for cancer diagnostics detects cancers and their tissues of origin using a unified model of cancers encompassing 33 cancers represented in The Cancer Genome Atlas. Their model exploits the learned features of different cancers reflected in the respective dysregulated epigenomes, holding a great promise in early cancer detection.

Article presents research that explores proanthocyanidin (PA) biosynthesis routes in plants. The data suggests that different species have evolved different routes for PA biosynthesis.

This article investigates global metabolic responses to lignin pathway perturbations in the model grass Brachypodium distachyon using a systems biology approach.

This article investigates the long-term effects of developmental hypoxia on mitochondrial function in a species that regularly encounters hypoxia during development. Findings speculate that adjustments might improve mitochondrial hypoxia tolerance, which would be beneficial for turtles during breath-hold diving and overwintering in anoxic environments.

Article indicating directions in which the field of Developmental Physiology might move. It suggests three categories of challenges: demonstrating broad relevance, promoting conceptual advances, and improving experimental approaches.

This article evaluates the role of endozoochory in herbivorous and sympatric bird species in sub-Antarctic Chile. The authors hypothesize that fragments of bryophyte gametophytes retrieved from their feces are viable and capable of regenerating new plant tissue. This relationship may have important implications in the way bryophytes disperse and colonize habitats facing climate change.

Article on the composition of the four cell wall fractions in diverse maize genotypes and to understand how this composition influences the resistance to pests, ethanol capacity and digestibility. Results evidence that there is no maize cell wall ideotype among the tested for optimal performance for various uses, and maize plants should be specifically bred for each particular application.

Article reports observations of two Subarctic North Pacific puffin species in the North Atlantic near the coast of north-west Greenland.

Article describing the isolation and genomic characterization of 116 phages that infect Microbacterium spp.

Article assessing range-wide genetic structure and contemporary gene flow in the thorn-tailed rayadito (Aphrastura spinicauda), a passerine bird inhabiting the temperate forests of South America.

Article integrating ecophysiological information with the development of new high-resolution climatic layers for Antarctica, to better understand how the distribution of P. steinenii may respond to change over the next century under different IPCC climate change scenarios. The authors conclude that the species has the potential to expand its distribution to include parts of the west and east coasts of the Antarctic Peninsula and even coastal ice-free areas in parts of continental Antarctica. The authors also propose P. steinenii as an effective native sentinel and indicator species of climate change in the Antarctic.

Article describes SERCA activity in the pectoralis muscle and heart ventricle of red-winged blackbird (Agelaius phoeniceus) nestlings, fledglings and adults. Additionally, using a diet manipulation, the authors tested the hypothesis that muscle SERCA activity is affected by dietary fatty acid composition, as has been shown in some previous studies.

Article describes study which tested if targeted and persistent changes in steady-state protein expression underlie this hypoxic heart phenotype, using isobaric tags for relative and absolute quantitation (iTRAQ) proteomics.

Article describes study which tested the hypothesis that developmental hypoxia alters cardiomyocyte physiology in a manner that protects the heart from hypoxic stress.

Article discusses the importance of valuing an alternative, ecological, aesthetic and post-modern-exotic hermeneutic in viewing Latin America, and discusses the colonial impression of a "exotic" Latin America.

Article discusses concerns and controversy related to the gold mining ‘Volta Grande Project’ at the Xingu River in northern Brazil.
