“…B irds are one of many favored pet animals in Indonesia; one of the species is the Stone Magpie (Putranto et al, 2018). Stone Magpies, known as Murai Batu, is native to Sumatera and Borneo Island, Indonesia (Mutiara et al, 2020;Sobiatin et al, 2019). Known for its impressive song, this bird has been recognized as the best songbird, according to Putranto et al (2018).…”

A previous study illuminated the influence of testosterone hormone and stress on bird songs, with the stress response being measured by their corticosterone levels. Since the data about Stone Magpie testosterone and corticosterone levels during songbird competition remains unreported, this study aims to investigate testosterone and corticosterone hormone levels in Stone Magpies before and after the songbird contest. Fecal samples were collected from twelve birds, distinguishing between amateur and experienced groups, both before and after the songbird contest, and preserved at -20°C. Corticosterone and testosterone hormone levels were assessed using an ELISA kit, and the acquired data were tested for normal distribution and homogeneity, followed by analysis through the T-test method. The results indicated an increment of testosterone and corticosterone hormones among experienced Stone Magpie birds after the contest; however, these changes did not reach statistical significance. The mean values, both before and after the contests, of testosterone levels in the amateur group did not show a significant difference. However, corticosterone levels in this group showed significant differences (P<0.05), with post-contest levels being higher than pre-contest. In the experienced group of Stone Magpie birds compared to the amateur group, the values of testosterone hormone showed higher results both before and after the contest. On the other hand, the corticosterone levels were lower than the amateur group, both before and after the contest. However, the statistical test did not indicate the significance of this difference. From the findings, it can be concluded that amateur birds were more stressed under the songbird contest whereas the experienced group displayed better performance, which may be related to their increased testosterone levels after the contest. However, our study did not show a direct relation between testosterone and corticosterone levels in Stone Magpie birds with their contest experience.

“…This technique is not appropriate because the leaves are detached from the life cycle and response of the plant. Second, different stomata were observed before, during, and after the SV treatment [26] producing an inconsistency in the stomata pore area results. Third, the use of adhesive materials or chemicals attached to the leaves in order to observe traces of stomata [27] that damaged the stomata and interfered with the stomata movement because stomata are very sensitive [28].…”

Effect of Sound Vibration towards the Stomata Opening Area via Edge Detection Analysis

2022

The effect of sound vibration (SV) towards plants had been studied for more than 30 years. Many results confirmed that SV influenced various parts of plants, e.g.: the stomata. However, the scientific community was still in doubt of these results. Hence, it is now a matter of giving further proofs and/or insights using new methods. This study aimed to determine the stomata pore movement influenced by SV with new observation and analysis technique based on edge detection. We had directly observed the abaxial stomata of Rhoeo discolor plant exposed by single SV frequencies of 0 Hz to 7000 Hz with an interval of 1000 Hz. The main device used in the observation was a microscope. The observation was conducted before, during, and after the SV exposure. The measurement of the stomata pore area utilized an image capture, which was then analyzed with edge detection technique. These edges were used as an indicator in the calculation of the stomata pore area in the pixel unit. The result showed that SV with frequency of 6000 Hz produced the largest stomata pore area, whereas the frequencies of 2000 Hz and 3000 Hz gave smaller stomata pore areas. Therefore, a single frequency of SV influenced the stomata pore area based on the edge detection analysis.
