To test the theory that leaf respiration rates are inherently higher in arctic species compared with temperate species, a total of 35 species from temperate, subarctic, and arctic locations were grown under controlled conditions and leaf respiration rates were measured. Regardless of growth temperature (either 10 or 20 °C), leaf respiration rates measured at the growth temperature were independent of a species' geographic origin. In addition, salicylhydroxamic acid inhibited the alternative oxidase equally in all groups of species. Acclimation of leaf respiration to temperature was observed in all three geographic plant groups, i.e., leaf respiration rates of 20 °C-grown plants were not significantly different than rates of 10 °C-grown plants when respiration was measured at the growth temperature. These results suggest that arctic species do not have inherently high leaf respiration rates, higher alternative pathway respiration, or greater temperature acclimation ability compared with temperate species. Keywords: alternative pathway respiration, arctic, leaf respiration, subarctic, temperate, temperature.

Vegetasi mangrove merupakan salah satu bagian penting dalam kehidupan masyarakat Papua. Penelitian dilakukan dengan observasi lapangan dan telah pustaka. Tujuan penelitian untuk mengetahui vegetasi mangrove yang dipergunakan sebagai bahan makanan pada empat suku yang ada di Papua Hasil penelitian menunjukkan terdapat 7 jenis dari 3 suku vegetasi mangrove yang dimanfaatkan sebagai makanan. Ke-7 jenis tersebut :Bruguiera gymnorrhiza Lam, Ceriops tagal B.Rob, Nypa fruticans Wurmb, Bruquiera parviflora, Rhizopora apiculata, Sonneratia alba J.Sm, dan Sonneratia avota dari 3 suku Rhizophoraceae, Sonneratiaceae, Arecaceae. Kegunaan vegetasi mangrove sebagai bahan makanan di antaranya: sebagai makanan pokok, rujakan, pengganti pinang, pengganti kelapa, penambah rasa, dan minuman.

The Impact

This study aims to describe the profile of vegetation diversity in the mangrove ecosystem in Tamuku Village, Bone-Bone-Bone District, North Luwu Regency. This research is a qualitative research using survey methods. The data collection technique uses the Quadrant Line Transect Survey technique. The data analysis technique uses the thinking flow which is divided into three stages, namely describing phenomena, classifying them, and seeing how the concepts that emerge are related to each other. The results of this study are the profile of mangrove vegetation in Tamuku Village, which is still found 16 varieties of true mangrove vegetation and 7 varieties of mangrove vegetation joined in the coastal area of Tamuku Village, Bone-Bone District, North Luwu Regency, South Sulawesi. The condition of mangrove vegetation in Tamuku Village is currently very worrying due to human activities that cause damage such as the project of normalization of flow, opening of new farms, disposal of garbage, water pollution due to chemicals, and exploitation of mangrove forests for living needs. The impact is ecosystem damage and reduced vegetation area as a place to grow and develop mangroves.
