age-period-cohort effects on the temporal trend mortality from male suicide in Brazil from 1980 to 2019
<p>The available files represent the records of deaths by suicide in men in Brazil and its major regions in the period from 1980 to 2019, in addition to the number of deaths after the correction process for the quality and coverage of deaths, for total suicides and suicides by weapon. of fire. The database for total and firearm suicides, represents the number of corrected deaths presented in age groups and periods grouped into five-year periods, which were used to carry out the analyzes of the effect of age, period and cohort, for total suicides and by weapon. of fire for Brazil and its great regions.</p> <p>.</p>
The effect of temporal changes in stamen position on reproductive success in flowers with many stamens: experimental manipulations of stamen position
<p class="MsoNormal"><span><strong>Premise of the study</strong>: </span><span>Male and female reproductive success is enhanced (increased outcrossing and seed production) by stamen movement</span><span> in species that have few stamens per flower.</span><span> Does such enhancement also occur in species that have many stamens per flower?</span></p> <p class="MsoNormal"><span><strong>Methods</strong>: </span><span>We examined the effects of stamen movement on male and female reproductive success in <em>Anemone flaccida</em>, which has </span><span>many stamens</span><span> per flower. We measured stamen movement, including temporal changes in anther-stigma and anther-anther distances. We controlled stamen movement experimentally.</span></p> <p class="MsoNormal"><span><strong>Key results</strong>: </span><span>The anthers moved horizontally away from the stigmas with increasing flower age, resulting in reduction in female-male interference. The dehisced anthers tended to move further away from the stigmas while the undehisced or dehiscing anthers remained nearer to them. The number of anthers touched per flower visit was higher in flowers whose stamens were fixed in the pre-movement position than in flowers whose stamens were fixed in the post-movement position or in flowers that were not manipulated. Thus, this position may promote male reproductive success. Seed production was lower for the untreated flowers than for the post-movement position flowers, suggesting that the post-movement stamen position is advantageous and stamen movement is suboptimal for female reproductive success.</span></p> <p class="MsoNormal"><span><strong>Conclusions</strong>: </span><span>Stamen movement promotes male reproductive success in the early flowering stage and female reproductive success in the late flowering stage. In species having many stamens per flower, female-male interference can be reduced, but not eliminated, by stamen movement due to the conflict between female and male reproductive successes.</span></p>

Data from: Diversification in temporally heterogeneous environments: effect of the grain in experimental bacterial populations.
Although theory established the necessary conditions for diversification in temporally heterogeneous environments, empirical evidence remains controversial. One possible explanation is the difficulty of designing experiments including the relevant range of temporal grains and the appropriate environmental tradeoffs. Here, we experimentally explore the impact of the grain on the diversification of the bacterium Pseudomonas fluorescens SBW25 in a temporally fluctuating environment by including twenty different pairs of environments and four temporal grains. In general, higher levels of diversity were observed at intermediate temporal grains. This resulted in part from the enhanced capacity of disruptive selection to generate negative genotypic correlations in performance at intermediate grains. However, the evolution of reciprocal specialization was an uncommon outcome. Although temporal heterogeneity is in theory less powerful than spatial heterogeneity to generate and maintain diversity, our results show that diversification under temporal heterogeneity is possible provided appropriate environmental grains.
