Abstract

fetched live from OpenAlex

ABSTRACT Breeding performance and offspring quality can be affected by temporal and spatial variation in ecological conditions. We analyzed the concomitant effects of timing of breeding, ambient temperature at different stages of the breeding cycle, and microhabitat conditions (presence or absence of livestock farming) on breeding success, morphology, and immunity of the offspring in an aerially insectivorous passerine bird, the barn swallow (Hirundo rustica). A seasonal decline in breeding success was observed, while maximum offspring phenotypic values of different characters were attained at different times in the breeding season, depending on presence or absence of livestock farming. In addition, environmental temperature at different stages of the breeding cycle (pre-incubation, incubation, and nestling stage) of individual pairs affected all the components of nestling phenotypic quality. The results of this correlational study suggest that parents are faced with complex decisions about optimal timing of breeding and microhabitat choice. In addition, different ecological factors seem to interact in influencing breeding success and offspring quality in the barn swallow. Natural and anthropogenic changes in ecological conditions, including ambient temperature and distribution of livestock, may therefore affect distribution and productivity of a population of a declining passerine species.

Teacher imitation

Not 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.
