Super excited that the bulk of my PhD work is now preprinted! Here we used whole-community competition, or coalescence, experiments to quantify selection acting on genetically diverged strains within larger communities. (1/n)

Cryptic female choice can maintain reproductive isolation
Abstract. Sexual selection has long been considered an important mechanism of speciation. Despite growing empirical evidence that postmating sexual selecti

Had a great time writing this quick guide on male alternative reproductive tactics (ARTs) with Suzanne Alonzo! Was a fun challenge to try and summarize everything that is so fascinating about male ARTs in ~1000 words.

Excited to share the preprint of my last PhD chapter, "Warm waters undermine cryptic female choice." We find that warm temperatures relevant to climate change reduce female influence on sperm velocity and expected paternity of preferred, dominant males in the ocellated wrasse.
Warm waters undermine cryptic female choice
Reproduction is often more thermally sensitive than survival. Thus, understanding the thermal sensitivity of reproductive interactions is crucial given global warming. However, it is unknown how tempe...

My first ever preprint!
@tylercarrier.bsky.social
and I hypothesized that reproductive manipulating microbes could shape the evolution of marine invertebrate developmental life-history. Using models, we provide insight into the conditions on when it is possible! www.biorxiv.org/content/10.1...

New preprint on how microbial manipulators—the aquatic relatives of Wolbachia—can serve as a mechanism to induce marine invertebrates to undergo transitions in developmental life-history.

I am an evolutionary ecologist that uses marine invertebrates—especially sea urchins and their echinoderm relatives—to study how microbial symbioses are essential to reproduction and development.

I'm finally getting around to doing my intro post. I'm a postdoc interested in the molecular interactions between the ejaculate and the female postmating, and their potential to contribute to reproductive isolation and speciation. 🧪👩‍🔬#HiSciSky #AcademicSky
