Chronic sleep deprivation could be an important driver of depression in young women

Recently published research in BMC Public Health finds an association between cumulative sleep deprivation and higher depression scores in young women but not in men, adding new evidence on the role of sleep deprivation in depression risk among young people and the influence of gender. Here to tell us about their findings and how their research took a different approach to previous studies are two of the authors, Annalijn I. Conklin and Christopher G. Richardson.

Deep genetic divergence among Bale monkeys in continuous forest and forest fragments

A new study, published in BMC Evolutionary Biology, investigates the population genetic structure and evolutionary history of the threatened, bamboo-eating Bale monkeys inhabiting the continuous forest of the Bale Mountains and fragmented forests of the Sidamo Highlands in southern Ethiopia. Surprisingly the authors find deep genetic differentiation between the two populations. Here, lead author, Dr. Addisu Mekonnen, tells us about the research and what it means for the conservation of this rare species.

Phenotypic plasticity in a pandemic lineage of the Irish potato famine pathogen

In a paper recently published in BMC Evolutionary Biology, an international team of scientists describes how evasion of host immunity by a clonal variant of the potato blight pathogen Phytophthora infestans is associated with variation in gene expression without any apparent underlying genetic changes. We asked the senior authors of the study, Vivianne G.A.A. Vleeshouwers, Hannele Lindqvist-Kreuze and Sophien Kamoun, to tells us about their work.

How do you solve a problem in palaeoproteomics?

The field of palaeoproteomics holds great potential for archaeologists and evolutionary biologists. In a paper recently published in BMC Evolutionary Biology, Frido Welker of the Max Planck Institute for Evolutionary Anthropology in Leipzig investigated the efficacy of error-tolerant searches for palaeoproteomic studies, highlighting some potential problems and solutions for studying whole proteomes from ancient hominin species.

Hawaiian spiders teach us about how explosive diversification happens

Adaptive radiation is the evolutionary process whereby a single ancestor can rapidly diverge into a wide variety of species according to different environmental conditions. It is a poorly understood process due to a lack of information on the critical early stage of divergence. Here, Darko Cotoras describes research published in BMC Evolutionary Biology performed by himself and colleagues that provides a missing link in the process of adaptive radiation.
