Diverse communities promote the coexistence of closely-related strains through emergent equalization and stabilization
Naven Narayanan Venkatanarayanan, Akshit Goyal
Microbial communities harbor extensive fine-scale diversity: closely-related strains of the same species coexist alongside many distantly-related taxa. Yet strain coexistence remai…
Energy flow controls the stability of multitrophic ecosystems with stratified nonreciprocity
Rukmani Ramachandran, Akshit Goyal
Complex systems with nonreciprocal interactions are often stratified into layers. Ecosystems are a prime example, where species at one trophic level grow by consuming those at anot…
Emergent self-inhibition governs the landscape of stable states in complex ecosystems
Nitesh Kumar Patro, Washington Taylor, Akshit Goyal
Species-rich ecosystems often exhibit multiple stable states with distinct species compositions. Yet, the factors determining the likelihood of each state's occurrence remain poorl…
Ecosystems as adaptive living circuits
Ankit Dhanuka, Avi I. Flamholz, Arvind Murugan +1
Unlike many physical nonequilibrium systems, in biological systems, the coupling to external energy sources is not a fixed parameter but adaptively controlled by the system itself.…
Energy-ordered resource stratification as an agnostic signature of life
Akshit Goyal, Mikhail Tikhonov
The search for extraterrestrial life hinges on identifying biosignatures, often focusing on gaseous metabolic byproducts as indicators. However, most such biosignatures require ass…
A universal niche geometry governs the response of ecosystems to environmental perturbations
Akshit Goyal, Jason W. Rocks, Pankaj Mehta
How ecosystems respond to environmental perturbations is a fundamental question in ecology, made especially challenging due to the strong coupling between species and their environ…
