Forest disturbances such as harvesting, wildfire and insect infestation are critical ecosystem processes affecting the carbon cycle. Because carbon dynamics are related to time since disturbance, forest stand age that can be used as a surrogate for major clear-cut/fire disturbance information has recently been recognized as an important input to forest carbon cyclemodels for improving predictio...

In this paper, two novel alkali clearable disperse dyes were synthesized. 4-flourosulfonyl aniline and 2-nitro-4-flourosulfonyl aniline were utilized as the diazo components and 2- naphthol as the coupling component. The DSC, FTIR, 1HNMR and UV-Vis analyses were used to characterize the synthesized intermediates and dyes. The synthesized dyes were used to dye polyester fibers and their dyeing p...

Social relationships are shaped by ecological conditions, giving rise to diverse societies even among related species. Among elephants, females exhibit close, often familial bonds with some degree of philopatry and fission–fusion dynamics. Forest elephant sociality is the least studied species, their ecology differs from that savannah Asian elephants. We use over 15 years data an individually i...
