Answer: I queried Wikidata for taxa whose taxon author citation (P6507) contains the string "Perrier" while excluding citations likely belonging to H. Perrier ("H.Perrier"). The query returns 33 candidate taxa. Note: Wikidata often records taxon authors as citation strings (P6507) rather than linking them to the author item (P405), so this string-based approach may include some false positives or miss taxa where Edmond Perrier is linked structurally. The returned taxa (IRIs and English labels when available) include items such as: Culcita veneris (wd:Q63406771), Digaster (wd:Q61609684), Digaster lumbricoides (wd:Q109340207), Diplodontias dilatatus (wd:Q2267779), Diplodontias singularis granulosus (wd:Q56055352), Rosaster (wd:Q3456339), Rosaster alexandri (wd:Q2781335), Spoladaster veneris (wd:Q2472752), Tarsaster fascicularis (wd:Q3275129), Ypsilothuria (wd:Q18380398), etc. If you want, I can return the full list of taxa (all 33 items) or try a different strategy (e.g., manual curation matching publication authorship).

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Search for the entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You have access to the following knowledge graphs:
wikidata at http://localhost:7001 without notes

You are provided with the following notes across all knowledge graphs:
No notes available

You can use the following SPARQL prefixes implicitly in all functions:

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- Do not use "SERVICE wikibase:label { bd:serviceParam wikibase:language ..." in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
- Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
- Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[Assistant] Step 4 — I'll search for taxa having P405 taxon author = wd:Q927667. I'll construct a SPARQL SELECT ?taxon WHERE { ?taxon wdt:P405 wd:Q927667 } and test it.

[Tool] Got no rows and 2 columns

[Assistant] I'll check how property P405 is used: list triples using property wdt:P405 and maybe property p:P405.

[Tool]
Got 2 rows and 3 columns:
| subject                                         | property                | object                          |
| ----------------------------------------------- | ----------------------- | ------------------------------- |
| Homotherium (wd:Q132606)                        | taxon author (wdt:P405) | Emilio Fabrini (wd:Q108170440)  |
| Furcularia boltoni [Gosse, 1886] (wd:Q18610360) | taxon author (wdt:P405) | Philip Henry Gosse (wd:Q443062) |

[Assistant] There are only two direct wdt:P405 entries; many taxa use the statement model (p:P405) with qualifiers. Let's search for items where the property is used at all: list property p:P405.

[Tool]
Got 2 rows and 3 columns:
| subject                                         | property              | object                                           |
| ----------------------------------------------- | --------------------- | ------------------------------------------------ |
| Homotherium (wd:Q132606)                        | taxon author (p:P405) | s:Q132606-873af6e8-40fb-5df5-0c09-f916abe86cb4   |
| Furcularia boltoni [Gosse, 1886] (wd:Q18610360) | taxon author (p:P405) | s:Q18610360-fe25f401-4594-8e57-5b7a-4bbfdcc98357 |

[Assistant] So P405 is sparsely used in wdt form. Many taxon items use property P577? No. Alternative approach: find taxa authored by Edmond Perrier from Edmond Perrier item: search properties of the person for "author abbreviation in zoology" P835 or "author name string" or "taxon author of" reverse. Search properties of Edmond Perrier that indicate he authored taxa.

Top 10 property alternatives:
1. contributed to creative work (wd:P3919 as wdt/p, matched via contributor), also known as collaborator on, contributed to, contributed to work, contributor, contributor to, etc.: person is cited as contributing to some creative or published work or series (qualify with "subject has role", P2868)

No other items found

[Assistant] I'll run a SPARQL query looking for taxa with a P405 statement whose ps:P405 value is Edmond Perrier (wd:Q927667). This handles cases where the property is recorded via statement nodes (p:) instead of direct wdt:.

[Assistant] It looks like direct usage of P405 for Edmond Perrier may be missing. Another approach: taxa items have "author citation" P6507 as string; we can search items where P6507 contains "Perrier" and then further filter by Edmond Perrier. Let's search for items with p:P6507 ps:P6507 "Perrier". I'll first see usage of P6507.

[Assistant] Many citations include "Perrier", but Edmond Perrier might be abbreviated as "E.Perrier" or "Perrier". We need to filter to only those taxa authored by Edmond Perrier (wd:Q927667). Author citations often are strings; some taxa may have an author item linked via P405 or through the "author name (zoology)" or similar. Alternatively, check if Edmond Perrier appears as the author in p:P50? Taxon items sometimes use P50 "author" (for publications) — not for taxa. Another route: search for statements where the author (P405) has a reference to Edmond Perrier? Or check items where the author string includes "E. Perrier" or "Edmond Perrier". Let's filter the citation string for "E. Perrier" or "Edmond".

[Assistant] This shows Elymus tangutorum cites "E. Perrier". We need to confirm that E. Perrier is Edmond Perrier (wd:Q927667). There may be multiple Perrier botanists (like H. Perrier is Joseph Marie Henry Alfred Perrier de la Bâthie, wd:QXXXX). Let's search for other Perrier persons.

[Assistant] Given difficulty matching strings to the specific person, another approach: find taxa items which have a linked author entity via qualifier? For instance, some statement might have pq:P2093 (author name string) and reference to an author item via pr:P50? Let's inspect one taxon that had citation "Perrier, 1872" such as Digaster lumbricoides (wd:Q109340207). I'll list its properties to see how authorship is recorded.

[Assistant]
This item uses P6507 as string only, not linking to an author item. There may be no unified mapping to Edmond Perrier. However, some taxa might have P405 property linking to a specific person, but earlier query for p:P405 had no matches for Edmond Perrier.

Alternative approach: find works authored by Edmond Perrier (publications) and then find taxa described in those works by linking "described in" P1343 to the taxon. If taxa have P1343 referencing the publication. Let's find publications authored by Edmond Perrier (wd:Q927667) using wdt:P50? For publications, property wdt:P50 is "author"? But search for works with author wd:Q927667: SELECT ?work WHERE { ?work wdt:P50 wd:Q927667 }.

[Assistant] Good — Edmond Perrier authored or co-authored many publications. Now find taxa that have described-in P1343 referencing any of these works. For example, see Digaster lumbricoides — does it have P1343? We saw only P6507 string and no P1343 in quick listing; but let's search taxa where p:P1343 ?stmt ps:P1343 ?work and ?work wdt:P50 wd:Q927667. Build query: find taxa ?taxon with p:P1343 ?stmt2 . ?stmt2 ps:P1343 ?work . ?work wdt:P50 wd:Q927667. Also include optional labels.

[Assistant] The filtered list excluding H. Perrier shows many taxa with citation "Perrier" which may be Edmond Perrier. Some entries have "Perrier E., 1886" explicitly. We should return taxa authored by Edmond Perrier (wd:Q927667). But SPARQL cannot easily reconcile string citations to the person. However, sometimes the taxon item includes a separate property "taxon author" P405 linking to an author item; but earlier we found no P405 matching Edmond. Maybe some taxa list the author as "Perrier E." via P2093 (author name string) or as a creator of the taxon via p:P405 with qualifiers? Let's inspect one taxon that likely is by Edmond Perrier, e.g., Ypsilothuria (wd:Q18380398). List its properties.

[Assistant] I need a method to map the author string to the person. Wikidata sometimes uses P2093 "author name string" on the taxon statement with a qualifier P1545? Let's inspect p:P6507 statement details for one taxon like Digaster (wd:Q61609684) and see qualifiers.

[Assistant]
The reference doesn't directly point to Edmond Perrier. So matching citations strings to Edmond Perrier is non-trivial.

However, the user's question: "What are the taxa authored by Edmond Perrier?" They probably expect a list of taxa for which Edmond Perrier is the taxon author. Since Wikidata doesn't consistently link strings to persons, the best we can do is retrieve taxa for which the taxon author (P405) is Edmond Perrier (wd:Q927667). Earlier, direct wdt:P405 query returned no rows. But maybe p:P405 with ps:P405 linking to a string or entity? Let's see if any p:P405 statements exist naming Edmond Perrier. Use query to find any statement where ps:P405 ?authorName and ?authorName is either wd:Q927667 or contains 'Edmond'. But ps:P405 can be an entity or literal — it's property with type unknown. Let's search p:P405 ?stmt . ?stmt ps:P405 ?author . FILTER(?author = wd:Q927667 OR contains string). But earlier we tried equal to wd:Q927667 and got none. Try filter(LCASE(str(?author)) contains "perrier").

[Tool] Got no rows and 3 columns

[Assistant] I'll run a final SPARQL query that returns taxa whose taxon author citation (P6507) contains "Perrier" but excludes likely different author abbreviations such as "H.Perrier" (Henri Perrier de la Bâthie). This is a pragmatic approach because many taxa record the author as a string (P6507) rather than linking to the person (P405). Caveat: this may include taxa by other Perrier family members if their citation strings don't include initials, and it may miss taxa linked via structured P405 to the person (none found). Now I'll execute the query to retrieve candidate taxa.

[Assistant] The query returns 33 taxa with citations containing 'Perrier' but excluding H. Perrier. This is likely a reasonable list of taxa authored by Edmond Perrier. I'll provide the final SPARQL query and the answer, and include a note about limitations (matching by citation string).
