Innovation rather than improvement: a solvable high-dimensional model highlights the limitations of scalar fitness

open access: yes, 2017
Much of our understanding of ecological and evolutionary mechanisms derives from analysis of low-dimensional models: with few interacting species, or few axes defining "fitness".

A Continuum From Positive to Negative Interactions Drives Plant Species' Performance in a Diverse Community

open access: yesEcology Letters, Volume 28, Issue 1, January 2025.
We explored the patterns of species performance in a real‐world community, dependent on pairwise and higher‐order interactions with species belonging to the same and other trophic levels (plant, herbivore and pollinator). We found that a continuum from positive to negative direct interactions, common to individuals in one guild,are sufficient to ...

DICHOTOMY OF AN IDEAL SWEETHEART’S IMAGE (THE STORY “NATALIE” BY I. A. BUNIN) [PDF]

open access: yesPhilology. Theory & Practice, 2019
The article identifies and analyses the psychological details, motives that create the image of Bunin’s integrated, but dichotomously split ideal heroine, “oxymoronic” in her nature. The paper shows that the psychological complexity of the heroine’s image casts its reflection on the personality of the hero, revealing the impossibility of achieving the ...

A note on the violation of the Einstein relation in a driven moderately dense granular gas

open access: yes, 2008
The Einstein relation for a driven moderately dense granular gas in $d$-dimensions is analyzed in the context of the Enskog kinetic equation. The Enskog equation neglects velocity correlations but retains spatial correlations arising from volume ...

Unpacking sublinear growth: diversity, stability and coexistence

open access: yesOikos, Volume 2025, Issue 1, January 2025.
How can so many species coexist in natural ecosystems remains a fundamental question in ecology. Classical models suggest that competition for space and resources should maintain the number of coexisting species far below the staggering diversity commonly found in nature.

Long-term neurocognitive function of pediatric patients with severe combined immune deficiency (SCID): pre- and post-hematopoietic stem cell transplant (HSCT). [PDF]

open access: yes, 2009
BACKGROUND:Hematopoietic stem cell transplantation (HSCT) is the only cure for patients with severe combined immunodeficiency (SCID). The purpose of this study was to evaluate long-term neurodevelopment of patients with SCID following myeloablative ...

The assembly and dynamics of ecological communities in an ever‐changing world

open access: yesEcological Monographs, Volume 94, Issue 4, November 2024.
Abstract Alternative perspectives on the maintenance of biodiversity and the assembly of ecological communities suggest that both processes cannot be investigated simultaneously. In this concept and synthesis, we challenge this view by presenting major theoretical advances in structural stability and permanence theory.

The interplay of facilitation and competition drives the emergence of multistability in dryland plant communities

open access: yesEcology, Volume 105, Issue 8, August 2024.
Abstract Within communities, species are wrapped in a set of feedbacks with each other and with their environment. When such feedbacks are strong enough they can generate alternative stable states. So far, research on alternative stable states has mostly focused on systems with a small number of species and a limited diversity of interaction types ...

France and the French in “Okayannye dni” by I. A. Bunin

open access: yesStudies in Theory of Literary Plot and Narratology, 2020
