Efecto de la disponibilidad de agua sobre una gramínea invasora del caldenal
Bibliographic record
Abstract
In the last years, in the semi-arid central region of Argentina, the increase of C3 non-palatable native grass species known generally as “pajas” was observed. One possible cause of the success of these species is the increase in rainfall observed in the region in recent years. The objective of this work was to evaluate the effect of a greater water availability and its seasonal distribution on the biomass and the production of reproductive structures of a non-palatable and highly invasive C3 species (Jarava ichu) and a non-palatable C4 species (Setaria lachnea). For this, a greenhouse experiment was carried out, consisting in manual irrigation of individuals of both species in pots. Treatments were: dry year, wet year with autumnal peak and wet year with spring peak. The increase in water availability favored the biomass of leaves and stems of J. ichu, independently of the seasonal distribution, with respect to the dry year. On the contrary, the biomass of S. lachnea did not respond to the different treatments (P>0.05). Likewise, the number of panicles was greater for J. ichu under the wet year treatment with spring peak, but there were no differences for S. lachnea.https://doi.org/10.25260/EA.19.29.1.0.763

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.
