Abstract

fetched live from OpenAlex

The Bachelor's thesis deals with the issue of invasive plant species. Following invasive plant species were mapped in the South Bohemian region of Třeboň: Canadian goldenrod (Solidago canadensis), Giant goldenrod (Solidago gigantea), Bohemian knotweed (Reynoutria x bohemica), Japanese knotweed (Reynoutria japonica), Sakhalin knotweed (Reynoutria sachalinensis) and Himalayan balsam (Impatiens glandulifera). The goal of this thesis was to map the above-mentioned species in one part of Stropnice Site of Community Importance and its surroundings. Furthermore, the thesis also aimed to record the most frequently colonized biotopes according to the invaded locations. The results show that Canadian goldenrod colonized seventeen locations and therefore it is one of the most invasive species. Next, Himalayan balsam was found in seven locations and Japanese knotweed in five locations. Last, Bohemian knotweed and giant goldenrod each colonized only one location. In this area, such species most often invade biotopes affected by people and locations near water resources. The plants also grow mostly in wet localities.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
