The frequency of sex in fungi

The frequency of sex in fungi | Science.education | Scoop.it

Fungi are a diverse group of organisms with a huge variation in reproductive strategy. While almost all species can reproduce sexually, many reproduce asexually most of the time. When sexual reproduction does occur, large variation exists in the amount of in- and out-breeding. While budding yeast is expected to outcross only once every 10 000 generations, other fungi are obligate outcrossers with well-mixed panmictic populations. In this review, we give an overview of the costs and benefits of sexual and asexual reproduction in fungi, and the mechanisms that evolved in fungi to reduce the costs of either mode. The proximate molecular mechanisms potentiating outcrossing and meiosis appear to be present in nearly all fungi, making them of little use for predicting outcrossing rates, but also suggesting the absence of true ancient asexual lineages. We review how population genetic methods can be used to estimate the frequency of sex in fungi and provide empirical data that support a mixed mode of reproduction in many species with rare to frequent sex in between rounds of mitotic reproduction. Finally, we highlight how these estimates might be affected by the fungus-specific mechanisms that evolved to reduce the costs of sexual and asexual reproduction.

Strategies for Reaching Quiet, Disengaged, Struggling, and Troublemaking Students

Strategies for Reaching Quiet, Disengaged, Struggling, and Troublemaking Students | Science.education | Scoop.it
Not every student benefits from in-class participation, immediate answers, inflexible grading, or harsh consequences. Learn the nuances for those requiring deeper recognition and a lighter touch.

John Kraus's curator insight, September 19, 9:20 PM
Not all quiet and disengaged students are "bad" students. Sometimes these students need a different approach, just like our typical "gifted" students many need a different approach to maximize their learning.
Amy Fulton's comment, September 20, 9:50 AM
I really enjoyed these ideas. I have been experimenting with trying to encourage struggling students to succeed in my classes this year. Gifted students struggle so much with perfectionism that I want them to learn to embrace the process of learning, so I am trying a new grading system. My class is pass/fail, so I decided to make each assignment follow the same policy. Students either earn a 1 or a 0 on the assignment, and each is given with a clear rubric so that students know what they need to do in order to earn the 1. If something isn't completed, I give them feedback on how to make sure that their assignment is up to 1 status. Then they can resubmit the assignment with corrections to earn their 1. It is going to take some getting used to for both me and the kids, but so far they seem to appreciate the idea that the assignment grade isn't final.
Amy Fulton's comment, September 20, 9:51 AM
Where I would like more advice is how to help disengaged students. Does anyone have any strategies that they would be willing to share?

Across most industries, there's a notable gender disparity at the very top. But in some sectors, including tech, it's hard for women to even get a foot in the door. A report from McKinsey released Tuesday (March 22) finds that women are "unable to enter" the technology, energy and basic materials, and automotive and industria
