Abstract

fetched live from OpenAlex

Исследование внутривидовой изменчивости трех функциональных признаков листьев: площади – LA, сухой массы – LDW и удельной площади – SLA показало их взаимообусловленность и зависимость значений признаков от благопритяности условий местообитания и антропогенной нагрузки. Анализ полученных данных исследования показал, что универсальные информационные показатели LA и LDW являются низкими в неблагоприятных и низкопродуктивных местообитаниях и более высокими при изобилии ресурсов в более продуктивных условиях существования. Полученные значения SLA видов растений, произрастающих в сообществах интенсивно эксплуатируемых пастбищ, часто имеют более высокие значения. Возможно, адаптация в условиях постоянного изъятия биомассы на сенокосах и пастбищах идет в первую очередь через сокращение массы листьев при сохранении листовой поверхности. В сообществах мезофитных лугов в условиях заповедного режима, характеризующихся высокой продуктивностью, показатели функциональных признаков всех исследованных видов выше по сравнению с менее продуктивными лугами, существующими в условиях дефицита увлажнения. Пастбищные нагрузки, оказывающие отрицательное воздействие на луговые пастбищные травостои, вызывают не только сокращение запасов общей биомассы лугового сообщества, но и изменение индивидуальных функциональных признаков видов растений, их образующих.

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.
