The thermodynamics of marine biogeochemical cycles: Lotka revisited
Nearly 100 years ago, Alfred Lotka published two short but insightful papers describing how
ecosystems may organize. Principally, Lotka argued that ecosystems will grow in size and …

How the second law of thermodynamics has informed ecosystem ecology through its history
Many attempts have been made to develop a general principle governing how systems
develop and organize in ecology. We reviewed the historical developments that led to the …

Microbial communities are well adapted to disturbances in energy input
Although microbial systems are well suited for studying concepts in ecological theory, little is
known about how microbial communities respond to long-term periodic perturbations …

Using maximum entropy production to describe microbial biogeochemistry over time and space in a meromictic pond
Determining how microbial communities organize and function at the ecosystem level is
essential to understanding and predicting how they will respond to environmental change …

Growth characteristics of natural microbial populations are skewed towards bacteria with low specific growth rates
Microbes are often functionally characterized by traits that specify their optimum
environmental conditions for growth, such as temperature or pH, as well as upper and lower …

Phytoplankton temporal strategies increase entropy production in a marine food web model
We develop a trait-based model founded on the hypothesis that biological systems evolve
and organize to maximize entropy production by dissipating chemical and electromagnetic …

Reactive transport modeling and biogeochemical cycling
This chapter focuses on some of the challenges arising in the modeling of microbially‐driven
systems. Building on a brief discussion of common modeling approaches, it discusses the …
