Are the results and conclusions based on analyses of data collected in protected areas representative of wider non-protected regions? We address this question by analysing some recently published data of alien plants in Greece. Mixed effects models were used with alien species presences in 8.25 x 8.25 km cells as dependent variable and the percentage of protected area, as well as the agricultural and artificial land cover types richne","authors_text":"Anneta Voutsela, Aristides Moustakas, Stelios Katsanevakis","cross_cats":["q-bio.PE","q-bio.QM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2017-12-26T08:48:30Z","title":"Sampling alien species inside and outside protected areas: does it matter?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.09210","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:f67954c39feec52c05a4eeb5eca3076db3b83b913ef1b5d04f60dadb1e3bc54b","target":"record","created_at":"2026-05-18T00:27:14Z","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":"eefddc9bacc65ee3b9354d2249818c797b672685dce2cda19532f746959e313d","cross_cats_sorted":["q-bio.PE","q-bio.QM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"stat.AP","submitted_at":"2017-12-26T08:48:30Z","title_canon_sha256":"c3e80681cf64416e200f0b2c3d6ce983ae609ad2c4301bc8458d2232a6f6ac35"},"schema_version":"1.0","source":{"id":"1712.09210","kind":"arxiv","version":1}},"canonical_sha256":"cc459a44b9ec076aba2434d96d014ea19855892f0743521849a0a7c367ebb9c0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cc459a44b9ec076aba2434d96d014ea19855892f0743521849a0a7c367ebb9c0","first_computed_at":"2026-05-18T00:27:14.185875Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:27:14.185875Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"euCFiNPXNsA33aQ/Aya3+G0Me+Kpz/u8ob8fo72OaM8nfb25UU+4uyg/0RsULEMRfyTRYt+eafOBdtR7uWizBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:27:14.186361Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.09210","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f67954c39feec52c05a4eeb5eca3076db3b83b913ef1b5d04f60dadb1e3bc54b","sha256:1294ffbdcae1a663dab37e19132bd13a40873936a1db212b01e1c6e2cd9e3cf8"],"state_sha256":"1781b20f243827148f26bab573e1dbe6359d7acceca704dfd8c0dcd3f93bbca4"}
