Higher-Order Competition as a Minimal Mechanism for Spatial Pattern Diversity in Population Dynamics
David Pinto-Ramos, Anudeep Surendran, Ricardo Martinez-Garcia
We show that negative feedback alone generates the diversity of self-organized shapes usually attributed to scale-dependent activation-inhibition. For a broad class of kernels, pai…
Global remote sensing reveals vegetation clustering as a physical footprint of shifting aridity trends in drylands
David Pinto-Ramos, Marcel Gabriel Clerc, Abdelkader Makhoute +1
Due to climatic changes, excessive grazing, and deforestation, semi-arid and arid ecosystems are vulnerable to desertification and land degradation. As aridity increases, vegetatio…
Self-organized vegetation patterns promote persistence of plant-pollinator mutualisms under environmental stress
Matheus Bongestab, David Pinto-Ramos, Ricardo Martinez-Garcia
Mutualisms are key for structuring ecological communities, but they are sensitive to environmental change and fluctuations in population size. Consequently, how mutualisms achieve…
How spatial patterns can lead to less resilient ecosystems
David Pinto-Ramos, Ricardo Martinez-Garcia
Several theoretical models predict that spatial patterning increases ecosystem resilience. However, these predictions rely on simplifying assumptions, such as assuming isotropic an…
Spatial moment dynamics and biomass density equations provide complementary, yet limited, descriptions of pattern formation in individual-based simulations
Anudeep Surendran, David Pinto-Ramos, Rafael Menezes +1
Spatial patterning is common in ecological systems and has been extensively studied via different modeling approaches. Individual-based models (IBMs) accurately describe nonlinear…
