Modification and evaluation of a ruminant emission measurement system for assessing cattle metabolism
Respiratory gas exchanges may be monitored to assess heat production as an indication of metabolic performance. A Ruminant Emission Measurement System (REMS) was initially constructed to measure methane emission from cattle, and is located at the Beef Cattle and Sheep Field Laboratory, the …

Deficit Irrigation Strategies on young orange trees (cv Tarocco Sciara)
… PAR, xylematic potential, canopy temperature, gas exchanges, trunk diameter and shoot number were carried out. Soil water content (SWC) was monitored by using Time (and Frequency) Domain Reflectometry. Preliminary results, obtained during the 2011 season, showed that: (i) xylematic potential …

Seasonal characteristics of phytoplankton bloom phenology in the northern Benguela Upwelling System
… and driving climate change through air-sea gas exchanges. Upwelling systems are particularly are sensitive to effects of climate change including the transport of nutrients, which influence the composition of phytoplankton communities. This is important because species composition affects a …

Morphological and Physiological Responses of Senegalia senegal (L.) Britton Provenances to Drought, Salinity, and Fertility
… the fertilizer effect on biomass increment. Leaf gas exchanges were affected by salinity and fertilizer within various responses among seed sources. Results of chapter 4 revealed that gum yield was found to be positively correlated with tree height, crown width, stem volume index and crown area …

PHENOTYPING OF GRAPEVINE ROOT SYSTEM FOR DROUGHT ADAPTATION
… Plants water status, above-ground growth and gas exchanges were recorded and root sections were sampled for anatomical traits observation. The two groups exhibited distinct responses to drought at both physiological and anatomical level. One group displayed a tolerance-oriented strategy …

Physiological and molecular determinants of the Chlamydomonas reinhardtii pyrenoid
… morphology and degrees of internalisation of gas exchanges. The results showed that on-line, carbon isotope discrimination values were a good indicator of CCM occurrence, as well as liquid-phase diffusion limitation, and biochemical limitations resulting from declining RuBisCO activity and …
