Juniper dwarf mistletoe (<i>Arceuthobium oxycedri</i>) in the Crimean Peninsula: novel insights into its morphology, hosts, and distribution
Bibliographic record
Abstract
Juniper dwarf mistletoe (Arceuthobium oxycedri (DC.) M. Bieb) is a semiparasitic species of Holarctic Cupressaceae hosts. This study updates the status of A. oxycedri and its hosts at the Crimean Peninsula, clearly defining them as principal (Eastern prickly juniper, Juniperus deltoides R.P. Adams), secondary (Greek juniper, J. excelsa M. Bieb.), occasional (rare) (Oriental thuja, Platycladus orientalis (L.) Franco), and uncommon (other representatives of Juniperus, Cupressus, and Chamaecyparis genera). Using eight morphological characteristics (aerial shoot length, basal diameter, 1st/2nd/3rd internode lengths and widths), we investigated aerial shoot morphology of male and female A. oxycedri plants on three hosts and found host-dependent differences. Parasites on P. orientalis, a nonprincipal host, at different sites are smaller by comparison with both juniper hosts. Anthesis, fruit ripening, and seed release are host-dependent as well. Two fly species (Diptera), common greenbottle (Lucilia ceasar L.), and dronefly (Eristalis tenax L.), were observed at peak of anthesis on male A. oxycedri inflorescences, suggesting they are involved in pollination. To our knowledge, we are presenting the first detailed study A. oxycedri distribution patterns in the Crimea, which appear to coincide with the range of J. deltoides at around 100 sites.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
