Similar methods have been applied also in spatially extended problems, relying on the fact that these populations are organized in colonies with a large local density of individuals. We provide a counterexample discussing a one-dimensional neutral population with negative frequency-dependent selection. The system exhibits a continuous phase transition between genetic fixation and coexistence unexpected from weak-noise arguments. We show that the behavior is a non-perturbative e","authors_text":"Deborah Begh\\`e, Fabio Caccioli, Luca Dall'Asta","cross_cats":["q-bio.PE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2010-12-06T15:56:26Z","title":"Strong Noise Effects in one-dimensional Neutral Populations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1012.1209","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:a715511b40716cf284ca73d5b5a1d98274a18876e4309ed3eacdf469ab18df5b","target":"record","created_at":"2026-05-18T02:23:15Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"995bbaa1c68660a1f3054200d76a655918e0a0b981c41e973f57669a3d70d35c","cross_cats_sorted":["q-bio.PE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2010-12-06T15:56:26Z","title_canon_sha256":"99cda2e39fce6c045e9d60255e2e24c69db88d8e4259bb7600b35465412ef6f3"},"schema_version":"1.0","source":{"id":"1012.1209","kind":"arxiv","version":1}},"canonical_sha256":"d9a5991f8f1b54b56a0969537af9d7f9f99cc5d7c4366ccce97c0c870b9ca768","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d9a5991f8f1b54b56a0969537af9d7f9f99cc5d7c4366ccce97c0c870b9ca768","first_computed_at":"2026-05-18T02:23:15.304328Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:23:15.304328Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DrR7gLSvSHtsDkRWydNo/GlllytjDpPhcaWlwSMqa1mwLWNpQB79OnfychDJOU6jzJz5r3i+7LZOhnm/Qb23AQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:23:15.304745Z","signed_message":"canonical_sha256_bytes"},"source_id":"1012.1209","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a715511b40716cf284ca73d5b5a1d98274a18876e4309ed3eacdf469ab18df5b","sha256:366085523148c364e888cf3157ca12fe035c9b638745cca9e1b36cba0398c6d0"],"state_sha256":"5af34546b7677383de559ed9a913fc6ea4eb7e3b52c16bad4dfbe74c7b7c1b6f"}
