Morphometric study of mantis shrimp Harpiosquilla harpax (De Haan, 1844) Corresponding author: alaksono@sci.ui.ac.id Abstract. Heat stress in cattle welfare is a growing concern because of increase in ambient temperature due to global warming. Physiological adaptation is as a way to survive and reproduce by regulation internal body temperature. West Sumbawa is a dry tropic area in eastern Indonesia where its temperature range is 24-38 °C and relative humidity is 50-90 %. This study aimed to determine the physiological response of indigenous cattle i.e. Bali cattle and Sumbawa Ongole cattle to the environment in West Sumbawa. Skin and rectal temperature and respiration rate within one minute were measured as physiology profiles from seven Bali cattle and two Sumbawa Ongole cattle. They were measured every 7.00 am and 15.00 pm for five consecutive days in August 2016. The results of measurements physiology profiles differ significantly between morning and afternoon among cattle breeds. Body temperature and respiration rate were significantly different among breeds (p < 0.05). Body temperature was lower but respiration rate of Sumbawa Ongole was higher than Bali cattle. Increased respiration rate of breeds was positively correlated with Temperature and Humidity Index (THI) value (p < 0.05), but neither was body temperature. Physiological response of Bali cattle to environmental West Sumbawa through the increase in body temperature, whereas Sumbawa Ongole cattle through increasing in respiration rate.
The objectives of this study were to evaluate the effect of leaf surface character on the ability of water hyacinth (Eichhornia crassipes (Mart.) Solms.) to transpire water. This experiment was performed using a healthy and acclimatized water hyacinth collected from Sawangan, Depok area. Five individual plants with the same size (6 leaves per plant), leaf length (10.4 ± 0.8 cm), leaf width (7.8 ± 0.7 cm) and root length (24.8 ± 7.4 cm) were put in each 20 L plastic tank containing tap water and allowed to grow in a greenhouse for six days. The transpiration rate of each plant was measured using a weighing method every day. The number of stomata, stomatal density and stomatal index were measured; amount of water loss from the individual plant through transpiration was analyzed. Based on the results of the study, it was found that the lowest leaf surface area is correlated with the number of stomatal and transpiration rates in the individual measured plants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
