Metabolism and gas exchange patterns in Rhodnius prolixus
(Pergamon-Elsevier Science Ltd, 2017-02)
Insect's metabolic rate and patterns of gas-exchange varies according to different factors such as: species, activity, mass, and temperature among others. One particular striking pattern of gas-exchange in insects is ...
Leaf gas exchanges responses of atemoya scion grafted onto Annona rootstocks
(2018-09-01)
We examined the hypothesis that leaf gas exchange of scion is affected by different rootstocks in wood plants. We investigated daily courses of gas exchange and photosynthetic potential using the CO2 assimilation rates as ...
Gas exchange and ventilation during dormancy in the tegu lizard Tupinambis merianae
(Company of Biologists Ltd, 1999-12-01)
The tegu lizard Tupinambis merianae exhibits an episodic ventilatory pattern when dormant at 17 degrees C but a uniform ventilatory pattern when dormant at 25 degrees C. At 17 degrees C, ventilatory episodes were composed ...
Gas exchange and ventilation during dormancy in the tegu lizard Tupinambis merianae
(1999-12-01)
The tegu lizard Tupinambis merianae exhibits an episodic ventilatory pattern when dormant at 17 °C but a uniform ventilatory pattern when dormant at 25 °C. At 17 °C, ventilatory episodes were composed of 1-22 breaths ...
A Rapidly-Incremented Tethered-Swimming Test for Defining Domain-Specific Training Zones
(2017-01-01)
The purpose of this study was to investigate whether a tethered-swimming incremental test comprising small increases in resistive force applied every 60 seconds could delineate the isocapnic region during rapidly-incremented ...
Analysis of the heart rate deflection point as a tool for exercise prescription in subjects with COPD - a cross-sectional study
(2019-01-01)
Background: Prescription of exercise training in subjects with chronic obstructive pulmonary disease (COPD) remains a challenge in clinical practice. The heart rate deflection point (HRDP) is an option to reduce costs, ...
Leaf gas exchange and yield of three upland rice cultivars
(Instituto Agronômico de Campinas, 2015-03-01)
Studies of physiological parameters associated with crop performance and growth in different groups of upland rice (Oryza sativa L.) may support plant breeding programs. We evaluated the role of gas exchange rates and dry ...
Photosynthetic efficiency of tomato plants submitted to calcium silicate application
(Univ Estadual Mato Grosso Sul, 2020-10-01)
The objective was to evaluate the effect of calcium silicate on the chlorophyll content and gas exchange of two tomato hybrids. The design used was in randomized blocks in a 2x5 factorial scheme, with four replications. ...
Acute effects of temperature and hypercarbia on cutaneous and branchial gas exchange in the South American lungfish, Lepidosiren paradoxa
(Elsevier B.V., 2017-01-01)
The South American lungfish, Lepidosiren paradoxa inhabits seasonal environments in the Central Amazon and Parana-Paraguay basins that undergo significant oscillations in temperature throughout the year. They rely on ...
Comparative gas exchange performance during the wet season of three Brazilian Styrax species under habitat conditions of cerrado vegetation types differing in soil water availability and crown density
(Elsevier Gmbh, Urban & Fischer Verlag, 2011-01-01)
We studied the influence of environmental conditions in different vegetation types of the Brazilian savanna (cerrado s.l.) on CO2 assimilation and water use efficiency of Styrax ferrugineus, S. camporum and S. pohlii, which ...
