Employing the reaction scheme mA->kA, but allowing, e.g., the product number k to be a-priori unknown and sampled from a given distribution, we show that such non-demographic noise can greatly reduce the population's extinction risk compared to the fixed k case. Our analysis is tested against numerical simulations, and by using empirical data of different species, we argue that certain distributions may be more","authors_text":"Michael Assaf, Shay Be'er","cross_cats":["cond-mat.stat-mech"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.PE","submitted_at":"2017-10-04T08:05:48Z","title":"Reducing the extinction risk of stochastic populations via non-demographic noise"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1710.01496","kind":"arxiv","version":2},"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:dbcc96788674c73d50e47e93cc62fc8ca20a866cd5ed225749a06f99389d1f0d","target":"record","created_at":"2026-05-18T00:21:54Z","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":"5b2ef4a42c4b0acdfe9c719ba99e5da48b3cb0e189b93e2bd206f1fc03b64ebc","cross_cats_sorted":["cond-mat.stat-mech"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"q-bio.PE","submitted_at":"2017-10-04T08:05:48Z","title_canon_sha256":"edee520767ef27bd225824724e1748f864a4237d48795f8bc459a29b45e901c4"},"schema_version":"1.0","source":{"id":"1710.01496","kind":"arxiv","version":2}},"canonical_sha256":"a5a0bec1740e9fda62a37eeef932e941608961f0574677785473da5872aec930","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a5a0bec1740e9fda62a37eeef932e941608961f0574677785473da5872aec930","first_computed_at":"2026-05-18T00:21:54.508352Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:21:54.508352Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Pt31uaBU9KcTnBhW9HaLdScCxlwT/ckykEAgDkNZqAIGQ5I/54puyz3FGgN+03oK62GvGSYIa751ZXh33I65BA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:21:54.509017Z","signed_message":"canonical_sha256_bytes"},"source_id":"1710.01496","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:dbcc96788674c73d50e47e93cc62fc8ca20a866cd5ed225749a06f99389d1f0d","sha256:cd0d5f1f4ba7533014b81989c44900af1ec131abd1d87bfaded0fd8122e96ef3"],"state_sha256":"b05c6073bd5ef1ca01f622c214d52d1395e938bfca1d0c855a9b747c07de2313"}
