Salmon usually return to their natal streams to spawn, presenting a risk of breeding between close genetic relatives.
By reducing heterozygosity, #inbreeding can deplete the genetic variability of a population, affecting offspring fitness and survival

However, #salmons are externally fertilisers and females are polyandrous. So how do females control #fertilisation when this occurs outside of their bodies?
Can they somehow hamper fertilisation from their siblings?#evolution may have allowed such mechanisms

To test this, we analysed #spermmotility in sibling vs non-sibling ovarian fluid, a substance released with eggs and involved in #sexualselection in #fish. Then, we compared #fertility & hatch rates between sib vs non-sib crosses after #invitro fertilisation

For my MSc by research @DICE_Kent I’m deciphering crest growth in #GreatCrestedNewts at individual and population levels. 🐸🦎

Male #GCNs grow ornamental crests every year during aquatic breeding period.
As UK seasons become less distinct, #pond arrival times are less predictable.
So what is happening with #crest development?🧐

We photographed >100 individual #newts over 2 breeding periods and tracked changes in crest size + shape using #ImageJ software.
Does early arrival = Early growth peak?
Or ⬆ growth period i.e. potential mating advantage?

Happy to be back in Sweden for my 2nd #BiologyofSperm meeting & hearing fascinating stories on evolution of sperm, gamete interactions, reproductive organs and strategies by fellow #spermnerds

Started strong yesterday with Sabine Koelle showing us the very first live imaging movies of sperm behavior in human reproductive tracts, all the way to the fertilization site, and even sperm filmed live swimming inside the testes! What a cool talk!
Next @lross_evoento told us about (incomplete) paternal genome silencing in fascinating mealybugs. @emwhitti brought us to the amazing world of Post-Ejaculatory Modifications w/ impressive proteomics data from 1000s of #drosophila reproductive tract dissections. #BoS2019 #BoS15
Ready for tomorrow and my first sessions of @SkypeScientist ! Looking forward to chatting, not with 1 , but 6 classes of middleschoolers! Send all the good vibes (and waves) my way for a good internet connection all day!

The morning started well with 2 different sessions with 2 classes of 7th graders from North Carolina @chowan_middle . Getting really cool questions about how it is to be a #scientist , why I chose to do what I do and how much I get to decide what I study.
