Loss of Migratory Traditions Makes the Endangered Patagonian Huemul Deer a Year-Round Refugee in Its Summer Habitat (open access)

Loss of Migratory Traditions Makes the Endangered Patagonian Huemul Deer a Year-Round Refugee in Its Summer Habitat

This article analyzes the historical spatiotemporal behavior of the huemul (Hippocamelus bisulcus), an endangered deer endemic to Patagonia. Losing migratory traditions is a major threat, and may explain their presently prevalent skeletal diseases, reduced longevity, and lacking recolonizations for most remaining huemul subpopulations.

Thermal Stress Has Minimal Effects on Bacterial Communities of Thermotolerant Symbiodinium Cultures (open access)

Thermal Stress Has Minimal Effects on Bacterial Communities of Thermotolerant Symbiodinium Cultures

Article comparing the microbial communities of three isolates from different species of the genus Symbiodinium (formerly known as Symbiodinium clade A) with different ecophysiology, levels of interaction with the animal host, and thermal adaptations. Results suggest that bacteria associated or co-cultured with thermotolerant Symbiodinium might play an important role in thermotolerance.

Subcellular localization of fungal specialized metabolites (open access)

Subcellular localization of fungal specialized metabolites

Article discusses how fungal specialized metabolites play an important role in the environment and have impacted human health and survival significantly. This review illustrates the biosynthesis of specialized metabolites where the localization of all, or some, of the biosynthetic enzymes have been determined and describes the methods used to identify the sub-cellular localization.

Transcriptional Programs and Regulators Underlying Age-Dependent and Dark-Induced Senescence in Medicago truncatula (open access)

Transcriptional Programs and Regulators Underlying Age-Dependent and Dark-Induced Senescence in Medicago truncatula

Article presents a study that reveals the dynamics of transcriptomic responses to age- and dark-induced senescence in M. truncatula and identifies senescence-associated TFs that are attractive targets for future work to control senescence in forage legumes.

Can X-Ray Observations Improve Optical-UV-based Accretion-rate Estimates for Quasars? (open access)

Can X-Ray Observations Improve Optical-UV-based Accretion-rate Estimates for Quasars?

Article presents a study utilizing a carefully selected sample of 53 radio-quiet quasars that have Hβ and C iv λ1549 spectroscopy as well as Chandra coverage, to search for a robust accretion-rate indicator for quasars, particularly at the highest-accessible redshifts (z ∼ 6–7).
