I’m a student at UMD working on my PhD with Dr. Heidi Fisher, here I’m investigating how evolutionary history & social environment impact reproductive traits.

And does this alter perceived sperm competition and mating duration? YES Mating duration was >2mins longer in males on clustered resources Closer patches ➡️ closer males ➡️ longer mating https://t.co/V3c0ZHSQY4 @mdfthom @jonrbridle @Elsevier

4/4 Work focusing on the incredible green anole #anoles #lizards #herpetology, is what led my curiosity toward reproductive biology. Thank you, Janson Jones @floridensis, for lending me these great photos. https://t.co/11tI4FWijq

3/4 By combining multiple methodologies we found individual male green anoles may distribute themselves according to size in the small urban population of Washington Square Park #NOLA, regardless of how they are related to one another.

2/4 Have you ever wondered why animals “post-up” where they do, or what benefits are gained by being bigger than another your same age? So did we! These are some of the questions that inspired my master’s thesis. The crux of my thesis is now published in @Ecol_Evol.

1/4 My mentors from the University of New Orleans @UofNO, Drs N Anthony and S Lailvaux @SLailvaux, and I have a new article “Size but not relatedness drives the spatial distribution of males within an urban population of Anolis carolinensis lizards” https://t.co/Yq3EqrcgFR

6/6 We see striking trait variation within treatment groups, which we predict is correlated with behavioral variation among males in the intruder introductions. We are currently scoring agonistic behaviors from videos, so stay tuned for more exciting results. #AnimBehav2021

5/6 We expected to see greater differences in the quality and quantity of sperm produced by males under variable social conditions. Perhaps not surprisingly, we also saw few differences in testosterone and corticosterone levels at the conclusion of the study. #AnimBehav2021

4/6 In the promiscuous P. maniculatus, we see something different: no difference in the sperm production traits among the treatment groups, but we find that intruders produce slower sperm, which may result from increased social stress or reproductive inactivity. #AnimBehav2021

3/6 In P. polionotus, we found residents had relatively smaller testes and lower sperm count than controls but did not differ from intruders. This may indicate that the stress leads to a decrease in reproductive investment in this pairbonded species. #AnimBehav2021

2/6 We used a resident-intruder assay to modulate stress and competition in both species, repeatedly introduced “intruder” males into “resident” (mated male) cages every other day for 35 days (>1 spermatogenesis cycle) to test the effects on sperm production. #AnimBehav2021

1/6 Social dynamics can be stressful, especially when vying for a mate. Ever wondered if that stress can affect reproductive traits? We did too! So, we tested it in two species of Peromyscus mice: the monogamous P. polionotus and the promiscuous P. maniculatus. #AnimBehav2021

I have had a tremendous year so far obtaining research funding. An enormous part of that is due to my extraordinary PhD advisor Dr. Heidi Fisher @heidisfisher. Every day I am amazed that I have been given the honor of working with her.

I would like to take a minute to thank Sigma Xi, the scientific research honor society @SigmaXiSociety for giving me additional support for my research on how social dynamics drive variation in male fertility.

I want to thank the American Society of Mammalogists @Mammalogists and the Society of Integrative & Comparative Biology @SICB_ who have both graciously funded my research on how social dynamics drive variation in male fertility.
