Understanding the evolution of ecological sex differences: Integrating character displacement and the Darwin‐Bateman paradigm

open access: yesEvolution Letters, 2019
Sex differences in selection arise for at least two possible reasons: (1) differences originating from anisogamy—the Darwin‐Bateman paradigm—and (2) competition‐driven ecological character displacement (ECD), agnostic of anisogamy.

The Opportunity for Post-Copulatory Sexual Selection in the Ectoparasitic Pea Crab, Dissodactylus primitivus (Brachyura: Pinnotheridae).

open access: yesPLoS ONE, 2015
Pea crabs, Dissodactylus primitivus, inhabit multiple echinoid (heart urchin) hosts. Male and female crabs move among hosts in search for mates, and both sexes mate multiple times, creating opportunities for post-copulatory sexual selection.

Relation of Adverse Childhood Experiences to Clinical and Patient‐Reported Outcomes for Adults With Sickle Cell Disease: A Registry Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adverse childhood experiences (ACEs) are stressful or traumatic events prior to age 18 that are known to have a lasting impact on individuals’ health and well‐being. There is a gap in understanding the relationship between ACEs and Other Life Stressors and health status for adults with sickle cell disease (SCD).
