A tale of two mistletoes: phenology and fauna associated with two sympatric species
Bibliographic record
Abstract
Mistletoes are parasitic plants that largely rely on animals for pollination and seed dispersal but establish complex interactions with their host plants. Mistletoes are considered keystone species in forest ecosystems as they facilitate several interactions. We studied the fauna associated with two sympatric mistletoe species ( Tristerix corymbosus (L.) Kuijt and Desmaria mutabilis (Poepp. & Endl.) Tiegh.) from the temperate rainforests of southern Chile. We set 40 camera traps from November 2021 to May 2022 to monitor the main pollinator (the hummingbird Sephanoides sephaniodes (R. Lesson & Garnot, 1827)), the main seed disperser (the arboreal marsupial Dromiciops bozinovici D’Elía, Hurtado & D’Anatro, 2016), and other animals (birds, mammals, reptiles, and insects). We compared fauna associated with Tristerix corymbosus between spring and summer–fall periods and between Tristerix corymbosus and Desmaria mutabilis during summer–fall. Species composition associated with Tristerix corymbosus showed a significant temporal variation, mainly explained by Sephanoides sephaniodes and Dromiciops bozinovici, which are more abundant in the summer–fall period. We found that animal species composition differences between mistletoe species were mainly explained by S. sephaniodes, Dromiciops bozinovici, and insects. While Tristerix corymbosus was mainly pollinated by hummingbirds, insects frequently visited Desmaria mutabilis flowers. Although both mistletoes have many similarities, they also have some phenology differences that affect their associations with animals, potentially influencing ecological processes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
