     This important work advances our understanding of the factors that affect the speed of colour evolution in birds and the resulting diversification patterns. It provides compelling evidence that more complex plumage coloration can lead to rapid colour evolution in kingfishers, and could pave the way for more comprehensive analyses that fully embrace the multidimensional nature of colour variation. Hence, the results will be of broad interest to ornithologists and evolutionary biologists in general, once the authors have streamlined the theoretical framework and explained the novel methodological approaches in more detail.

     This valuable manuscript describes a fully automated touchscreen cognitive testing system for rats that reduces the length of training required to learn a task and eliminates the need for daily handling. These features make it possible to assess cognitive behaviors in conjunction with other neurobehavioral paradigms during adolescence, an important advance in the field. The data convincingly show that cognitive flexibility does not promote susceptibility to severe weight loss in the activity-based anorexia (ABA) paradigm. However, support for the claim that cognitive deficits seen in rats that had been exposed ABA adequately capture an important clinical feature of the pathophysiology of anorexia nervosa is incompletely supported.

     This study provides fundamental insights into the relationship between single neuron activity in superficial layers of the cortex and electrical signals recorded at the cortical surface. Based on solid measurements, the results indicate a weak correlation between individual layer 2/3 neuron activity and multiunit activity recorded at the surface, whose interpretation could be reinforced. In particular, a strong contribution of layer 1 axons to surface signals is suggested but relies on incomplete evidence.

     This manuscript provides valuable insight into the molecular mechanism by which destabilized mitochondrial proteins 'clog' import channels and contribute to the pathologic mitochondrial and cellular dysfunction implicated in human disease. The evidence supporting this conclusion is solid, utilizing yeast, mammalian cell culture, and mouse models. However, additional characterization of import clogging in the mammalian model systems would strengthen this study. This work will be of broad interest to researchers in the fields of mitochondrial biology, protein quality control and proteostasis.

     This manuscript tests an important assumption about how sensory information is processed and used to guide motor choices. The widely held assumption is that sensory-motor circuits are capable of integrating evidence, but the validity and generality of this 'principle' have been recently questioned by studies suggesting that other computational operations may lead to similar psychophysical results, mimicking integration without actually performing it. This study makes a compelling case that the integration assumption was likely correct all along and that the model mimicry can be easily disambiguated by using appropriate sensory stimuli and task designs that permit rigorous analyses.

     This important study provides convincing evidence that locus coeruleus is activated during visuomotor mismatches. Gain of function optogenetic experiments complement this evidence and indicate that locus coeruleus could be involved in the learning process that enables visuomotor predictions. This study, therefore, sets the groundwork for the circuit dissection of predictive signals in the visual cortex. Loss-of-function experiments would strengthen the evidence of the involvement of locus coeruleus in prediction learning. These results will be of interest to systems neuroscientists.

     The paper provides a valuable, in-depth mathematical analysis of the coevolutionary dynamics resulting from a coupling of players' strategies and (collective) risk, as well as illustrative numerical simulations of the system's trajectories for different starting conditions. It is therefore a solid contribution to our understanding of how cooperation can be sustained when there is feedback between individual decisions and the global risk of disaster. This paper will be of interest to scientists working on mathematical biology/ecology, and more generally various aspects of human decision-making, the interplay between human decisions and the environment, and public goods provision.

     This study addressed a long-standing question in biology - the role of fever during infections. Using innovative research strategy, the authors provide compelling evidence for the positive impact of higher body temperature on both pathogen clearance and tissue repair. This study thus provides important advances in our understanding of host defense and its connection with physiology and behavior.

      This manuscript reports novel and important findings on the mechanisms of regulation of CRAC channels. Collectively, the work represents an important conceptual advancement, showing that stromal interaction molecule-1 is not necessary for Ca2+-dependent inactivation of the Orai1 channel and that Orai1 likely contains a Ca2+ sensor for autoregulatio. The experiments are carefully conducted, and the data is of high quality and support the major conclusions of the authors.
