REVIEW
Louis Bernatchez, Maren Wellenreuther, Cristián Araneda, David T Ashton, Julia M I Barth, Terry D Beacham, Gregory E Maes, Jann T Martinsohn, Kristina M Miller, Kerry A Naish, Jennifer R Ovenden, Craig R Primmer, Young Suk Ho, Nina O Therkildsen, Ruth E Withler
Best use of scientific knowledge is required to maintain the fundamental role of seafood in human nutrition. While it is acknowledged that genomic-based methods allow the collection of powerful data, their value to inform fisheries management, aquaculture, and biosecurity applications remains underestimated. We review genomic applications of relevance to the sustainable management of seafood resources, illustrate the benefits of, and identify barriers to their integration. We conclude that the value of genomic information towards securing the future of seafood does not need to be further demonstrated...

Paolo Gratton, Silvio Marta, Gaëlle Bocksberger, Marten Winter, Petr Keil, Emiliano Trucchi, Hjalmar Kühl
A recent global analysis of GenBank DNA sequences from amphibians and mammals indicated consistent poleward decrease of intraspecific genetic diversity in both classes. We highlight that this result was biased by not accounting for distance decay of similarity and reanalyse the datasets, revealing distinct latitudinal gradients in mammals and amphibians.

#5
REVIEW
Gregory F Grether, Kathryn S Peiman, Joseph A Tobias, Beren W Robinson
Behavioral interference between species, such as territorial aggression, courtship, and mating, is widespread in animals. While aggressive and reproductive forms of interspecific interference have generally been studied separately, their many parallels and connections warrant a unified conceptual approach. Substantial evidence exists that aggressive and reproductive interference have pervasive effects on species coexistence, range limits, and evolutionary processes, including divergent and convergent forms of character displacement...

#6
REVIEW
Calum S Campbell, Colin E Adams, Colin W Bean, Kevin J Parsons
Unprecedented rates of species extinction increase the urgency for effective conservation biology management practices. Thus, any improvements in practice are vital and we suggest that conservation can be enhanced through recent advances in evolutionary biology, specifically advances put forward by evolutionary developmental biology (i.e., evo-devo). There are strong overlapping conceptual links between conservation and evo-devo whereby both fields focus on evolutionary potential. In particular, benefits to conservation can be derived from some of the main areas of evo-devo research, namely phenotypic plasticity, modularity and integration, and mechanistic investigations of the precise developmental and genetic processes that determine phenotypes...

#7
REVIEW
Jon F Harrison
Hypometric scaling of aerobic metabolism in animals has been widely attributed to constraints on oxygen (O2) supply in larger animals, but recent findings demonstrate that O2 supply balances with need regardless of size. Larger animals also do not exhibit evidence of compensation for O2 supply limitation. Because declining metabolic rates (MRs) are tightly linked to fitness, this provides significant evidence against the hypothesis that constraints on supply drive hypometric scaling. As an alternative, ATP demand might decline in larger animals because of performance-safety tradeoffs...

#8
REVIEW
James A R Marshall, Gavin Brown, Andrew N Radford
Group-living species frequently pool individual information so as to reach consensus decisions such as when and where to move, or whether a predator is present. Such opinion-pooling has been demonstrated empirically, and theoretical models have been proposed to explain why group decisions are more reliable than individual decisions. Behavioural ecology theory frequently assumes that all individuals have equal decision-making abilities, but decision theory relaxes this assumption and has been tested in human groups...

#9
REVIEW
Megan E Frederickson
Mutualisms teeter on a knife-edge between conflict and cooperation, or so the conventional wisdom goes. The costs and benefits of mutualism often depend on the abiotic or biotic context in which an interaction occurs, and experimental manipulations can induce shifts in interaction outcomes from mutualism all the way to parasitism. Yet, research suggests that mutualisms rarely turn parasitic in nature. Similarly, despite the potential for 'cheating' to undermine mutualism evolution, empirical evidence for fitness conflicts between partners and, thus, selection for cheating in mutualisms is scant...

#10
REVIEW
Graeme S Cumming, Garry D Peterson
Ecosystems influence human societies, leading people to manage ecosystems for human benefit. Poor environmental management can lead to reduced ecological resilience and social-ecological collapse. We review research on resilience and collapse across different systems and propose a unifying social-ecological framework based on (i) a clear definition of system identity; (ii) the use of quantitative thresholds to define collapse; (iii) relating collapse processes to system structure; and (iv) explicit comparison of alternative hypotheses and models of collapse...

Good writing takes time, but in a research environment where speed is master, is it a superfluous pursuit? Scientists spend most of their working life writing, yet our writing style obstructs its key purpose: communication. We advocate more accessible prose that boosts the influence of our publications. For those who change, the proof of their success will be science that is read, understood, and remembered.

#12
REVIEW
Julia C Buck, William J Ripple
Most demonstrated trophic cascades originate with predators, but infectious agents can also cause top-down indirect effects in ecosystems. Here we synthesize the literature on trophic cascades initiated by infectious agents including parasitoids, pathogens, parasitic castrators, macroparasites, and trophically transmitted parasites. Like predators, infectious agents can cause density-mediated and trait-mediated indirect effects through their direct consumptive and nonconsumptive effects respectively. Unlike most predators, however, infectious agents are not fully and immediately lethal to their victims, so their consumptive effects can also trigger trait-mediated indirect effects...

#20
REVIEW
Nathan W Burke, Russell Bonduriansky
Theory suggests that occasional or conditional sex involving facultative switching between sexual and asexual reproduction is the optimal reproductive strategy. Therefore, the true 'paradox of sex' is the prevalence of obligate sex. This points to the existence of powerful, general impediments to the invasion of obligately sexual populations by facultative mutants, and recent studies raise the intriguing possibility that a key impediment could be sexual conflict. Using Bateman gradients we show that facultative asexuality can amplify sexual conflict over mating, generating strong selection for both female resistance and male coercion...
