Method of meal delivery influences estimates of postprandial metabolism and alkaline tide in a benthic fish

open access: yesJournal of Fish Biology, EarlyView.
Abstract Intragastric gavage is widely used in studies of digestive physiology to deliver standardised meals, yet it remains unclear whether it elicits postprandial metabolic and acid–base responses comparable to voluntary feeding. Here, we tested whether the method of meal delivery affects the magnitude and timing of the postprandial rise in metabolic

Improved primary production and gross respiration measurements using the H218O technique with membrane inlet mass spectrometry and introduction of a small volume–uniform irradiance incubation chamber

open access: yesJournal of Phycology, EarlyView.
Abstract An improvement in the H218O technique for phytoplankton gross primary productivity (GPP), net primary productivity (NPP), and gross respiration (GR) is described that reduces cost, labor, and time over the traditional isotope ratio mass spectrometer (IRMS) method.

Soft Tissue Substitutes: Current Biomaterials and Indications at Teeth and Implant Sites

open access: yesJournal of Periodontal Research, EarlyView.
This manuscript provides an updated overview of the current evidence on soft tissue graft substitutes for teeth and dental implants. When appropriately indicated, these biomaterials offer a reliable, less invasive alternative to autogenous grafts, effectively improving root coverage, keratinized mucosa width, and soft tissue thickness with reduced ...

Insights into plant‐part‐specific N2O production in roots and shoots of chicory (Cichorium intybus) using stable isotope labelling

open access: yesNew Phytologist, EarlyView.
Conceptual scheme of the nitrous oxide (N2O) production, consumption, and transport processes across the soil–plant–atmosphere continuum. Summary Nitrous oxide (N2O) contributes substantially to climate change and stratospheric ozone degradation, yet large uncertainties in its global budget point to overlooked sources.

Climate drivers of mesophyll conductance: temperature and water deficit alter CO2 diffusion and leaf anatomy in cotton

open access: yesNew Phytologist, EarlyView.
Temperature responses of photosynthesis, mesophyll conductance and stomatal conductance to water across Gossypium hirsutum cv Sicot 71, Gossypium arboreum, Gossypium bickii, Gossypium gossypioides and Gossypium sturtianum. Summary Mesophyll conductance (gm) limits CO2 delivery to Rubisco, yet its responses to temperature, heat and water deficit are ...
