10/12/2022: New paper out today! Through a great collaboration with colleagues in Austria we found that there is great variation between species in one genus of harvestmen (Opiliones) in the array of chemical compounds they secrete! We also found that the composition can vary between juveniles and adults even in the same species. Open access paper here in Frontiers of Ecology and Evolution.

1/18/2022: How would losing legs affect the reproduction of animals that use their legs to court? In our latest paper we explored this question in males of a species of harvestmen from Costa Rica. We found that males that lost two sensory or locomotor legs had similar mating success as eight-legged males. This suggests the robustness of these animals to morphological damage, and the absence of fitness consequences of leg loss in this group. Open-access article here.

1/11/2022: New paper out today! We reviewed the benefits and costs of mixed-species aggregations in harvestmen (Opiliones, 'daddy long-legs'), studied the potential benefits and costs of these aggregations in seven species from Costa Rica, and found that new individuals from different species join the groups every day! Open-access article here.

8/02/2021: I was interviewed (along with other researchers) for a great article on The Atlantic on the evolution and function of legs in harvestmen. Article here. 

7/14/2021:  New paper out! When harvestmen (daddy long-legs) lose sensory legs their habitat use changes, but their survival seems unaffected. Open access paper here.
