Ecological drift during colonization drives within- and between-host heterogeneity in animal symbiont populations

J. Chen, Z. Kwong, N. M. Gerardo, N. M. Vega

The paper shows ecological drift drives microbiome heterogeneity in squash bugs, both between and within hosts, without requiring host-mediated selection.

Effects of a field-sprayed antibiotic on bee foraging behavior and pollination in pear orchards

L. Avila, C. McCullough, A. Schiffer, J. Moreno, N. Ganjur, Z. Ofenloch, S. T. DuPont, L. Nottingham, N. M. Gerardo, B. J. Brosi

This study examines the effects of antibiotic spraying on bee foraging behavior and pollination in pear orchards, finding reduced bee visits but no impact on pollination success.

Evaluating the role of coevolution in a horizontally transmitted mutualism

K. S. Stoy, J. Chavez, V. De Las Casas, V. Talla, A. Berasategui, L. T. Morran, N. M. Gerardo

The paper tests coevolutionary dynamics in a horizontally transmitted mutualism between squash bugs and their bacterial symbionts, finding no evidence of local or specialized adaptation.

The importance of environmentally-acquired bacterial symbionts for the squash bug (Anasa tristis), a significant agricultural pest

T. S. Acevedo, G. P. Fricker, J. R. Garcia, T. Alcaide, A. Berasategui, K. S. Stoy, N. M. Gerardo

This study shows that squash bugs acquire beneficial Burkholderiaceae bacteria from the environment, which enhance their survival and development, and can be transmitted to future generations.

Population genomics reveals complex patterns of immune gene evolution in monarch butterflies (Danaus plexippus)

W.-H. Tan, A. J. Mongue, J. C. de Roode, N. M. Gerardo, J. R. Walters

This study examines immune gene evolution in monarch butterflies, finding that immune genes show varied evolutionary patterns, with signaling genes being conserved and modulation genes showing relaxed selection.
