Habitat and Distribution of the Ruffed Lemur,<i>Varecia</i>, North of the Bay of Antongil in Northeastern Madagascar
Bibliographic record
Abstract
Here we present information on the conservation status of ruffed lemurs (Varecia) north of the Bay of Antongil in northeastern Madagascar. Two contiguous protected areas were recently established that traverse this region via blocks of forest connected by narrow forest corridors: the Masoala National Park, which expands further to the east, and the Makira Protected Area, which expands further to the west and northwest. The two extant ruffed lemurs, Varecia variegata and V. rubra, overlapped in this region historically and, on rare occasions, hybridized. As such, land north of the Bay of Antongil is a critical part of the ruffed lemur's northern geographic range. Habitat surveys and interviews with local informants were carried out in this region to determine the extent of suitable habitat for Varecia populations, to assess the extent of human exploitation of this genus, and to obtain data on the western and northern range limits of V. rubra. Interviews indicated that there are populations of V. rubra as degradation and lemur hunting in the three major river drainages north of the Bay of Antongil. The recent establishment of protected forest blocks and forest corridors in the region was critical, as these links will provide the only connections between Varecia populations that would otherwise be entirely isolated in forest patches surrounded by agricultural land. The geo-referenced habitat survey and the summary of interview results provided here can be used as comparators for future population and habitat assessments following the establishment of the protected areas. A primary direction for future work should be to examine how Varecia populations are adapting to conditions in and near forest corridors.

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.
