Hybridization selects for prime-numbered life cycles in Magicicada: An individual-based simulation model of a structured periodical cicada population.

ABSTRACT: We investigate competition between separate periodical cicada populations each possessing different life-cycle lengths. We build an individual-based model to simulate the cicada life cycle and allow random migrations to occur between patches inhabited by the different populations. We show that if hybridization between different cycle lengths produces offspring that have an intermediate life-cycle length, then predation acts disproportionately to select against the hybrid offspring. This happens because they emerge in low densities without the safety-in-numbers provided by either parent population. Thus, prime-numbered life cycles that can better avoid hybridization are favored. However, we find that this advantage of prime-numbered cycles occurs only if there is some mechanism that can occasionally synchronize emergence between local populations in sufficiently many patches.

Project description:ObjectivesSimulation is widely employed to teach a range of skills, across healthcare professions and is most effective when embedded within a standarised curriculum. Although recommended by many governing bodies, establishing a national programme of simulation presents many challenges. Successful implementation requires a clear understanding of the priorities and needs of those it seeks to serve yet there are limited examples of how best to do this. This study aimed to develop an integrated national simulation-based educational programme for junior doctors in Scotland through a structed, multistep prioritisation process.DesignA series of action research cycles were undertaken to develop and evaluate a national simulation programme. This paper describes cycle 1, which employed a six-step structured approach to understand and prioritise learner needs.SettingThe study considered the educational needs of Scottish junior doctors in the UK Foundation Programme (UKFP).ParticipantsMultiple stakeholder groups were involved in each stage of the process including recent Scottish UKFP graduates, clinical educators, UKFP programme directors and postgraduate deans.ResultsKey stakeholders reviewed the 370 competencies in the UKFP curriculum and identified 18 initial competency areas. These 18 areas were subsequently prioritised through the analytical hierarchy process, resulting in a carefully ordered list of 12 competencies from which a targeted simulation-based educational programme could be developed.ConclusionsTo our knowledge, this is the first study to outline the methods of competency prioritisation to create a simulation curriculum that is integrated within a national curriculum in the medical education context. As well as demonstrating the practical steps of such a process, key implications for practice are identified. This robust approach to educational design also resulted in unexpected benefits, including educator and clinician acceptance and programme funding sustainability.

Project description:In terrestrial snails, thermal selection acts on shell coloration. However, the biological relevance of small differences in the intensity of shell pigmentation and the associated thermodynamic, physiological, and evolutionary consequences for snail diversity within the course of environmental warming are still insufficiently understood. To relate temperature-driven internal heating, protein and membrane integrity impairment, escape behavior, place of residence selection, water loss, and mortality, we used experimentally warmed open-top chambers and field observations with a total of >11,000 naturally or experimentally colored individuals of the highly polymorphic species Theba pisana (O.F. MÜller, 1774). We show that solar radiation in their natural Mediterranean habitat in Southern France poses intensifying thermal stress on increasingly pigmented snails that cannot be compensated for by behavioral responses. Individuals of all morphs acted neither jointly nor actively competed in climbing behavior, but acted similarly regardless of neighbor pigmentation intensity. Consequently, dark morphs progressively suffered from high internal temperatures, oxidative stress, and a breakdown of the chaperone system. Concomitant with increasing water loss, mortality increased with more intense pigmentation under simulated global warming conditions. In parallel with an increase in mean ambient temperature of 1.34°C over the past 30 years, the mortality rate of pigmented individuals in the field is, currently, about 50% higher than that of white morphs. A further increase of 1.12°C, as experimentally simulated in our study, would elevate this rate by another 26%. For 34 T. pisana populations from locations that are up to 2.7°C warmer than our experimental site, we show that both the frequency of pigmented morphs and overall pigmentation intensity decrease with an increase in average summer temperatures. We therefore predict a continuing strong decline in the frequency of pigmented morphs and a decrease in overall pigmentation intensity with ongoing global change in areas with strong solar radiation.
