Very belated post about the amazing @thefsbi.bsky.social and @ifmfish.bsky.social confernce we just had in Belfast. The science was incredible, the people were amazing. Pretty sure I didn't get to talk to all ~160 of you, but I had the best time, and it's feeling very quiet without you!!

We found that choosing "highly informative loci" (aka high fst loci) may bias results in common population genetic analyses

Saturday was Remembrance Day for Lost Species, honoring species lost to the #extinctioncrisis. Last year we lost 21 species to the extinction crisis.

Every lost species threatens to unravel ecosystems and in the process reduce the services they provide.

PhD Advert - title "Examining ecological shifts and impacts of adaptive divergence in response to geothermal habitats"

Climate change poses a major threat to biodiversity, but some populations will undergo ecological shifts to persist with impacts on the supporting ecosystem. How this will occur is unknown but in some areas of geothermal warming provides unique opportunities to investigate the ecological impacts of a warmed habitat.

In Iceland’s geothermally warmed habitats, we have discovered several populations of threespine stickleback. This has driven adaptive divergence in metabolism, morphology, and behaviour (Pilakouta et al 2020, 2023). However, evidence also suggests that ecological differences in diet occur. This could drive much of the adaptive divergence observed, while also impacting the broader community.

This project will look directly at the dietary changes that occur in these populations to better understand the ecological drivers of thermally-driven adaptive change. To achieve this the project will address three main aims:

1. Analysis of long-term dietary variation between populations from geothermal and ambient habitats (across multiple locations)
2. Assess ontogenetic variation in diet to determine at what life stage ecological divergence occurs
3. Tests of heritable divergence in diet preferences, performance, and bioenergetic partitioning through the use of lab-rearing and mesocosm experiments

A very exciting PhD on the ecological implications of divergence & adaption to warm water habitats in 3-spined sticklebacks combining field work in Iceland, mesocosms, tank studies & lab-work in the UK. Great team, lots of exciting ideas and techniques to test them.

Climate change is a 'natural' process now occurring ~10 times faster than the average rate after an ice age. Extinction is 'natural' but is now occurring 1000X faster than in past eras (apart from mass extinctions). Biological invasion is now at rates 100000X prehistoric levels of spp colonisations.
