Sexual selection protects against extinction : Nature : Nature Publishing Group

Sexual selection protects against extinction : Nature : Nature Publishing Group | my universe | Scoop.it
Reproduction through sex carries substantial costs, mainly because only half of sexual adults produce offspring. It has been theorized that these costs could be countered if sex allows sexual selection to clear the universal fitness constraint of mutation load. Under sexual selection, competition between (usually) males and mate choice by (usually) females create important intraspecific filters for reproductive success, so that only a subset of males gains paternity. If reproductive success under sexual selection is dependent on individual condition, which is contingent to mutation load, then sexually selected filtering through /`genic capture/' could offset the costs of sex because it provides genetic benefits to populations. Here we test this theory experimentally by comparing whether populations with histories of strong versus weak sexual selection purge mutation load and resist extinction differently. After evolving replicate populations of the flour beetle Tribolium castaneum for 6 to 7 years under conditions that differed solely in the strengths of sexual selection, we revealed mutation load using inbreeding. Lineages from populations that had previously experienced strong sexual selection were resilient to extinction and maintained fitness under inbreeding, with some families continuing to survive after 20 generations of sib [times] sib mating. By contrast, lineages derived from populations that experienced weak or non-existent sexual selection showed rapid fitness declines under inbreeding, and all were extinct after generation 10. Multiple mutations across the genome with individually small effects can be difficult to clear, yet sum to a significant fitness load; our findings reveal that sexual selection reduces this load, improving population viability in the face of genetic stress.

Study suggests STEM faculty hiring favors women over men | InsideHigherEd | my universe | Scoop.it

Many studies suggest that women scientists aspiring to careers in academe face roadblocks, including bias -- implicit or overt -- in hiring. But a new study is throwing a curveball into the literature, suggesting that women candidates are favored 2 to 1 over men for tenure-track positions in the science, technology, engineering and math fields. Could it be that STEM gender diversity and bias awareness efforts are working, or even creating a preference for female candidates -- or is something more nuanced going on? Experts say it’s probably both....

how is silkworm sex determined? 

..., researchers ... have finally discovered that a small, PIWI-interacting RNA molecule (piRNA) produced by the female chromosome is the determining factor of femaleness in the worms (1). It’s the first known instance of a non-coding RNA molecule determining sex, and the finding paves the way toward not only new breeding techniques for silkworms but also a better understanding of the regulation of small RNA molecules.

Genomic breeding for food, environment and livelihoods - Rivers &al (2015) - Food Sec

Genomic breeding for food, environment and livelihoods - Rivers &al (2015) - Food Sec | my universe | Scoop.it

Land use management is a central challenge for the 21st century with unprecedented and competing demands to produce food, feed/fodder, fibre, fuel, and essential ecosystem services which sustain life. Global change requires rapid adaptation in current and emerging crops as well as in the foundation species of natural ecosystems.

 

Revolutions in genomics and high throughput experimentation are transforming breeding so that adaptive traits in new environments can be predicted and selected more directly from germplasm collections of crops and wild species. This genomic breeding is now feasible in almost any species and has promise to help meet the need to feed and nourish over 9 billion people by 2050.

 

Genomic techniques can accelerate our response to food security challenges of yield, quality and resilience and also address environmental security challenges. To achieve its potential there will need to be widespread and ongoing investments in the human capital to promote genomic breeding... 

 

Advanced plant science and genomics have revolutionised breeding and crop improvement, and will continue to do so. Innovation in collecting genotypes, phenotypes, and intermediate characteristics, is allowing new crop varieties to be selected faster and more accurately than ever before.

 

With genomic techniques researchers can help address food security challenges of yield, quality, resilience, and other environmental and social needs. Investing in the human capital to perform genomic breeding is needed to improve food security, environments and livelihoods.
