Family Matters: Linking Population Growth, Kin Interactions, and African Elephant Social Groups.

AbstractIn many species, individuals are embedded in a network of kin with whom they interact. Interactions between kin can affect survival and fertility rates and thus the life history of individuals. These interactions indirectly affect both the network of kin and the dynamics of the population.

Sea level rise and the evolution of aggression on islands.

Why aggressive traits evolve in some species but not in others is poorly understood. We modeled the population dynamics of the extinct Mauritius dodo and Rodrigues solitaire to examine divergent pathways in the evolution of aggression. Whereas the dodo conformed to island syndrome predictions of tameness, its sister-taxon the solitaire evolved strong sexual dimorphism and aggressive traits.

Accounting for temporal and individual variation in the estimation of Von Bertalanffy growth curves.

Growth and growth limitation are important indicators of density dependence and environmental limitation of populations. Estimating individual growth trajectories is therefore an important aspect of understanding and predicting the life history and dynamics of a population. Variation in individual growth trajectories arises due to variation in the environmental factors limiting individual growth.

Treatment Retention in Older Versus Younger Adults with Opioid Use Disorder: A Retrospective Cohort Analysis from a Large Single Center Treatment Program.

Objective: To compare treatment retention in a Medication for Opioid Use Disorder program between older and younger adults with opioid use disorder.

Methods: This retrospective cohort study was conducted from 2015 to 2018 at an urban academic hospital's opioid and drug treatment center. Participants were adults, 18 and older, diagnosed with Opioid Type Dependence.
