TL;DR: In this article, the authors show that climate change may lead to large-scale redistribution of global catch potential, with an average of 30-70% increase in high-latitude regions and a drop of up to 40% in the tropics.
Abstract: Previous projection of climate change impacts on global food supply focuses solely on production from terrestrial biomes, ignoring the large contribution of animal protein from marine capture fisheries. Here, we project changes in global catch potential for 1066 species of exploited marine fish and invertebrates from 2005 to 2055 under climate change scenarios. We show that climate change may lead to large-scale redistribution of global catch potential, with an average of 30-70% increase in high-latitude regions and a drop of up to 40% in the tropics. Moreover, maximum catch potential declines considerably in the southward margins of semienclosed seas while it increases in poleward tips of continental shelf margins. Such changes are most apparent in the Pacific Ocean. Among the 20 most important fishing Exclusive Economic Zone (EEZ) regions in terms of their total landings, EEZ regions with the highest increase in catch potential by 2055 include Norway, Greenland, the United States (Alaska) and Russia (Asia). On the contrary, EEZ regions with the biggest loss in maximum catch potential include Indonesia, the United States (excluding Alaska and Hawaii), Chile and China. Many highly impacted regions, particularly those in the tropics, are socioeconomically vulnerable to these changes. Thus, our results indicate the need to develop adaptation policy that could minimize climate change impacts through fisheries. The study also provides information that may be useful to evaluate fisheries management options under climate change.

TL;DR: In this paper, the authors focused on the problem of lake eutrophication by excessive phosphorus (P) input and analyzed management policies for ecosystems subject to alternate states, thresholds, and irreversible changes.
Abstract: We analyzed management policies for ecosystems subject to alternate states, thresholds, and irreversible changes. We focused on the problem of lake eutrophication by excessive phosphorus (P) input. Eutrophic lakes may be classified, with respect to their response to reduced P input alone, as reversible (recovery is immediate and proportional to the reduction in P input), hysteretic (recovery requires extreme reductions in P input for a period of time), or irreversible (recovery cannot be accomplished by reducing P input alone). A model with one state variable and one control variable describes the responses of lake trophic state to changes in P input and other management interventions. Activities that generate P input to the lake are assumed to create profits, while the value of ecosystem services provided by the lake declines at high P levels. We then calculated P input policies that maximize the discounted net benefits from polluting activities and ecosystem services. If “optimality” is defined as maxim...

TL;DR: The current understanding of how and why sex determination evolves in animals and plants is reviewed.
Abstract: Sexual reproduction is an ancient feature of life on earth, and the familiar X and Y chromo- somes in humans and other model species have led to the impression that sex determination mecha- nisms are old and conserved. In fact, males and females are deter- mined by diverse mechanisms that evolve rapidly in many taxa. Yet this diversity in primary sex-deter- mining signals is coupled with conserved molecular pathways that trigger male or female develop- ment. Conflicting selection on dif- ferent parts of the genome and on the two sexes may drive many of these transitions, but few systems with rapid turnover of sex determi- nation mechanisms have been rig- orously studied. Here we survey our current understanding of how and why sex determination evolves in animals and plants and identify important gaps in our knowledge that present exciting research op- portunities to characterize the evo- lutionary forces and molecular pathways underlying the evolution of sex determination.

TL;DR: The structural convergence of the IIP circumplex scales with an established measure of interpersonal dispositions, the Revised Interpersonal Adjective Scales, was examined.
Abstract: We constructed a set of circumplex scales for the Inventory of Interpersonal Problems (IIP; Horowitz, Rosenberg, Baer, Ureno, & Villasenor, 1988) Initial scale construction used all 127 items from this instrument in two samples of university undergraduates (n = 197; n = 273) Cross-sample stability of item locations plotted against the first two principal components was high A final set of eight 8-item circumplex scales was derived from the combined sample (n = 470) and cross-validated in a third university sample (n = 974) Finally, we examined the structural convergence of the IIP circumplex scales with an established measure of interpersonal dispositions, the Revised Interpersonal Adjective Scales (IAS-R; Wiggins, Trapnell, & Phillips, 1988) Although both circumplex instruments were derived independently, they shared a common Circular space Implications of these results are discussed with reference to current research methods for the study of interpersonal behavior

TL;DR: Treatment of atopic dermatitis with nonpharmacologic interventions and pharmacologic topical therapies are reviewed and suggestions on dosing and monitoring are given based on available evidence.
Abstract: Atopic dermatitis is a common and chronic, pruritic inflammatory skin condition that can affect all age groups. This evidence-based guideline addresses important clinical questions that arise in its management. In this second of 4 sections, treatment of atopic dermatitis with nonpharmacologic interventions and pharmacologic topical therapies are reviewed. Where possible, suggestions on dosing and monitoring are given based on available evidence.
