Variación temporal de la abundancia y diversidad de aves del humedal del río Mataquito, Región del Maule, Chile
Bibliographic record
Abstract
Coastal wetlands support high biological diversity. However, in Chile there is a lack of information in terms of the structure and dynamics of bird assemblages in this kind of ecosystems. To investigate the importance of the Mataquito River wetland for waterbirds, we conducted seasonal censuses between 2006 and 2010. We evaluated waterbird diversity, characterized the temporal pattern of the assemblage and used an Indicator Species Analysis (IndVal) to identify those bird species that characterize the temporal pattern of the assemblage structure. We recorded 54 bird species belonging to 18 families, which represent 41% of the Chilean waterbird species. The 81% of the species were resident, 17% were visitant, and 2% were sporadic. Larus pipixcan, Rynchops niger, Pelecanus occidentalis, Thalasseus elegans, Larus modestus and Haematopus palliatus were the most abundant species. The assemblage structure did not show a clear temporal pattern. Indicator Species Analysis showed that Rynchops niger, Egretta alba, Egretta thula, Anas georgica and Thalasseus elegans characterized the summer-autumn period. Due to its high species richness, this wetland has an important role for migrant and resident waterbird species.

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; both teacher heads agree on what is shown here.
