demogR: A Package for the Construction and Analysis of Age-structured Demographic Models in R

The analysis of matrix population models has become a fundamental tool in ecology, conservation biology, and life history theory. In this paper, I present demogR, a package for analyzing age-structured population models in R.

Bridging Performance and Fate: A Framework for Sustainable, Composite‐Based Flexible Electronic Systems

Advanced Electronic Materials, EarlyView.
Composite‐based flexible electronics integrate biodegradable polymers, conductive networks, and multilayer device architectures to balance electrical performance, mechanical durability, and controlled degradation. Interfacial engineering and encapsulation regulate transport stability and operational lifetime, while programmed disassembly enables ...

The evolutionary ecology of metacommunities

, 2008
International audienceResearch on the interactions between evolutionary and ecological dynamics has largely focused on local spatial scales and on relatively simple ecological communities.

On the Economics of US Agricultural Policy

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This paper presents an economic analysis of US agricultural policy, building on a modified version of Gardner's efficient redistribution. We argue that agricultural policy is motivated as an attempt to implement an efficient redistribution scheme that redistributes income toward farmers who, as a group, have been adversely affected by ...

Experiments in Ecology and Evolutionary Biology

, 2009
Most of the philosophical work done on experimentation has focused on the physical sciences, i.e., physics and chemistry. I consider to what extent this work is relevant to experimentation in ecology and evolutionary biology, and will identify some ...

Hemp Cultivation and Crop Diversification: Implications for Ecosystem Services in Kentucky

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the ecosystem benefits of expanding hemp cultivation by assessing its impact on crop diversity. Using scenario‐based simulations and fixed‐effect panel regressions with county‐level data in Kentucky, we find that increased hemp acreage tends to enhance crop diversity, improving water quality and bird diversity.

Ecological and Evolutionary Consequences of Herbivory on Plant Communities

, 2014
Understanding the consequences of species interactions is central to ecological and evolutionary research. My research focused on better understanding the evolutionary ecology of plant- herbivore interactions by asking two broad questions: 1) How do ...

Animal models in molecular biology research: Challenges, ethical imperatives, and the path to human‐relevant translation

Animal Models and Experimental Medicine, EarlyView.
The graphical abstract shows how molecular biology research has shifted from using traditional animal models toward using methods that are more relevant to humans. It points out the main problems, differences between species, difficulty in reproducing results, moral issues, and lack of infrastructure that make translational accuracy harder to achieve ...
