mignette: An R package for creating and visualizing migratory network models

Methods in Ecology and Evolution
A prominent challenge for managing migratory species is the development of conservation plans that accommodate spatiotemporally varying distributions throughout the year.

The American Kestrel (Falco sparverius) genoscape: implications for monitoring, management, and subspecies boundaries

Ornithology, 2021
AbstractIdentifying population genetic structure is useful for inferring evolutionary process and comparing the resulting structure with subspecies boundaries can aid in species management. The American Kestrel (Falco sparverius) is a widespread and highly diverse species with 17 total subspecies, only 2 of which are found north of U.S./Mexico border ...

A general theory of avian migratory connectivity

Ecology Letters, Volume 24, Issue 9, Page 1848-1858, September 2021., 2021
Despite much research describing migratory behaviour, the underlying forces driving how a species’ breeding and wintering populations redistribute each year, that is, migratory connectivity, remain largely unknown. Here, we test the hypothesis that birds migrate in a way that minimises energy expenditure while considering intraspecific competition for ...

Disentangling the relative roles of climate and land cover change in driving the long‐term population trends of European migratory birds

Diversity and Distributions, Volume 26, Issue 11, Page 1442-1455, Novemeber 2020., 2020
Abstract Aim Global declines in the populations of migratory species have been attributed largely to climate change and anthropogenic habitat change. However, the relative contribution of these factors on species’ breeding and non‐breeding ranges is unclear.

Linked dynamic abundance models as the basis for a full‐annual‐cycle, integrated population model

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Understanding distinct vital rates (birth, death, immigration, and emigration) is a common goal in studies of ecological populations because separately estimating these rates and their drivers allows better prediction of population growth in unsurveyed areas and in the future.
