Data and code for: No evidence of metabolic costs following adaptive immune activation or reactivation in house sparrows
<p>We examined the energetic costs of immune activation by measuring both basal (BMR) and exercise-induced maximal metabolic rates (MMR) in house sparrows before and after being injected with either saline (sham) or two novel antigens (keyhole limpet haemocyanin and sheep red blood cells; KLH and SRBC, respectively) after the primary and two subsequent vaccinations. We also examined the effect of experimentally-induced breeding levels of testosterone (T) on immune responses and their metabolic costs in both males and females. </p>

LIBER 2019 Workshop. Open Access books in academic libraries – how can we adapt workflows and cost management to an open scholarly communications landscape?
<p>This dataset includes all the results from a workshop held at the LIBER Annual Conference 2019 on June 26, 2019, in Dublin, Ireland. The workshop aimed at collecting and discussing current library practices related to open access books.</p> <p>The dataset includes information from a survey made in preparation for the conference, where 67 European libraries responded to a questionnaire based on activities or workflows in libraries related to open access books. Both the survey questionnaire and the results from the survey are uploaded as separate files.</p> <p>The dataset also includes the presentation made by keynote speaker Eelco Ferwerda from the OAPEN Foundation. He presented results based on the 2017 landscape study report on open access monographs with some new results from more recent studies by Springer Nature and a follow-up report by Knowledge Exchange.</p> <p>Olaf Siegert from ZBW - Leibniz Information Centre for Economics presented a brief overview of what libraries can do to promote OA books in terms of collection management, publication services and development of staff and organisation. The conclusion is that it is not necessarily big changes that are needed.</p> <p>Sofie Wennström presented results from a survey aimed at European research libraries on behalf of the LIBER Open Access Working Group. The survey reveals that many libraries are already working with processes to promote OA books. This is done by libraries organising publishing services or inhouse publishing, by including OA books in discovery services and repositories and by supporting authors to learn more about open access and open licensing.</p> <p>Finally, the LIBER Open Access Working Group shares a report from the workshop providing some quick takeaways and some good examples brought up during the breakout session with the workshop participants.</p>

Data from: Tradeoffs affect the adaptive value of plasticity: Stronger cannibal-induced defenses incur greater costs in toad larvae
<p>Adaptive developmental plasticity allows individuals to match their phenotype with their environment, which can increase fitness where threats are inconsistently present. Because adaptive traits are not ubiquitously nor infinitely plastic, tradeoffs between benefits and costs or limits are theoretically necessary to constrain plastic responses. Systems in which extreme risk can be reliably detected are ideal for investigating mechanisms that constrain plasticity, as even costly responses may be adaptive where risk is severe. Cane toads (<em>Rhinella marina</em>) are abundant in Australia and produce large clutches (frequently >10,000 eggs), but asynchronous breeding and rapid development result in variable larval densities within breeding pools. In the field, we found that cannibalism by older cohorts often reduces the survival of conspecific eggs and newly hatched pre-feeding larvae ("hatchlings") by >99%, as feeding larvae ("tadpoles") use chemical cues from the relatively immobile hatchlings to locate and consume them. After hatchlings become free-swimming, however, they are safe from cannibalism. Hatchlings can reduce this period of vulnerability by accelerating development when they detect conspecific tadpole cues. However, this developmental acceleration decreases initial tadpole mass, reduces subsequent survival, growth, and development, affects behavior, and compromises feeding structures. Reaction norms differ among clutches, and greater developmental acceleration is followed by greater impairment of larval function in plastic clutches, whereas nonresponsive clutches are unaffected by exposure to cannibal cues. More plastic clutches ultimately exhibit both poorer performance and greater variation among siblings in exposed and (to a lesser degree) control treatments. Variation among clutches in tadpole viability is driven by differences in plasticity rather than phenotype; fitness reductions are linked to developmental acceleration, not rapid development <em>per se</em>. Clutches with intrinsically slow pre-feeding developmental rates exhibit stronger acceleration (i.e., steeper reaction norms), but clutches with intrinsically rapid development reach invulnerable stages more quickly than those that accelerate development. As a result, high cannibalism risk may favor canalized rapid development rather than facultative developmental acceleration. Cannibalism plays an important role in the recruitment of this invasive species, and hatchling defenses against this threat demonstrate how the limits and tradeoffs associated with an inducible defense can favor canalized defenses over phenotypic plasticity.</p>

Benefit-cost analysis of adaptation objectives to coastal flooding at the global scale
<p>This dataset presents results of benefit-cost analyses of different adaptation objectives using grey infrastructure to coastal flooding at the global scale. </p> <p>The four adaptation objectives are: (1) ‘Protection constant’, which keeps protection levels in the future the same as current protection levels; (2) ‘Absolute risk constant’, which calculates future protection standards when the absolute value for expected annual damage is kept the same as current; (3) ‘Relative risk constant’, which calculates future protection standards when expected annual damage as a percentage of GDP is kept the same as current; and (4) ‘Optimize’, which calculates future protection standards by maximizing net present value.</p> <p>The results for each adaptation objective include future protection standards, change in risk relative to GDP, benefit-cost ratio and net present value for various RCP-SSP combinations for sub-national regions.</p>

Male adaptive plasticity can explain the evolution of sexual perception costs
<p>Sensory perception of environmental cues has been shown to trigger plastic responses that can induce important fitness costs, including the dramatic modulation of ageing across distant taxa. For example, male Drosophila melanogaster suffer a marked decrease in fitness, including faster reproductive and actuarial ageing, if they perceive female cues but fail to mate shortly after (ageing via sexual perception). While this has been a breakthrough for our understanding of the mechanisms of ageing, it poses the question as to why such plastic responses evolved. Here, we used D. melanogaster to ask whether sexual perception costs may be a by-product of plastic adaptive responses to female cues. We found that: a) short-term (1 day) perception of female cues prior to mating opportunities increases male relative lifetime reproductive success in a competitive environment, b) medium-term (3-7 days) perception is neutral, and c) long-term (15 days) perception leads to reproductive costs. We then ran mathematical simulations under a wide range of socio-sexual and demographic scenarios to show that such plastic male responses can be adaptive whenever mating rates fluctuate within the range experienced by D. melanogaster and other insects in the wild, suggesting this may be a widespread strategy in nature. Finally, we show that, because the short-term benefits of plastic responses will be mostly acquired by high-quality males while long-term costs will be mostly paid by low-quality males, sexual perception can significantly magnify sexual selection (15-27% average increase in the opportunity for selection).</p>

Data from: Adaptation costs to constant and alternating polluted environments
Some populations quickly adapt to strong and novel selection pressures caused by anthropogenic stressors. However, this short-term evolutionary response to novel and harsh environmental conditions may lead to adaptation costs, and evaluating these costs is important if we want to understand the evolution of resistance to anthropogenic stressors. In this experimental evolution study, we exposed Caenorhabditis elegans populations to uranium (U populations), salt (NaCl populations), alternating uranium/salt treatments (U/NaCl populations), and to a control environment (C populations), over 22 generations. In parallel, we ran common-garden and reciprocal-transplant experiments to assess the adaptive costs for populations that have evolved in the different environmental conditions. Our results showed rapid evolutionary changes in life history characteristics of populations exposed to the different pollution regimes. Furthermore, adaptive costs depended on the type of pollutant: pollution-adapted populations had lower fitness than C populations, when the populations were returned to their original environment. Fitness in uranium environments was lower for NaCl populations than for U populations. In contrast, fitness in salt environments was similar between U and NaCl populations. Moreover, fitness of U/NaCl populations showed similar or higher fitness in both the uranium and the salt environments compared to populations adapted to constant uranium or salt environments. Our results show that adaptive evolution to a particular stressor, can lead to either adaptive costs or benefits once in contact with another stressor. Furthermore, we did not find any evidence that adaptation to alternating stressors was associated with additional adaption costs. This study highlights the need to incorporate adaptive cost assessments when undertaking ecological risk assessments of pollutants.
