Soil C/N ratios cause opposing effects in forests compared to grasslands on decomposition rates and stabilization factors in southern European ecosystems

Soils store an important amount of carbon (C), mostly in the form of organic matter in different decomposing stages. Hence, understanding the factors that rule the rates at which decomposed organic matter is incorporated into the soil is paramount to better understand how C stocks will vary under changing atmospheric and land use conditions. We studied the interactions between vegetation cover, climate and soil factors using the Tea Bag Index in 16 different ecosystems (eight forests, eight grasslands) along two contrasting gradients in the Spanish province of Navarre (SW Europe). Such arrangement encompassed a range of four climate types, elevations from 80 to 1420 m.a.s.l., and precipitation (P) from 427 to 1881 mm year–1. After incubating tea bags during the spring of 2017, we identified strong interactions between vegetation cover type, soil C/N and precipitation affecting decomposition rates and stabilization factors. In both forests and grasslands, increasing precipitation increased decomposition rates (k) but also the litter stabilization factor (S). In forests, however, increasing the soil C/N ratio raised decomposition rates and the litter stabilization factor, while in grasslands higher C/N ratios caused the opposite effects. In addition, soil pH and N also affected decomposition rates positively, but for these factors no differences between ecosystem types were found. Our results demonstrate that soil C flows are altered by complex site-dependent and site-independent environmental factors, and that increased ecosystem lignification will significantly change C flows, likely increasing decomposition rates in the short term but also increasing the inhibiting factors that stabilize labile litter compounds.This work was supported by the Public University of Navarre; the Spanish Ministry of Science [grant numbers AGL2016-76035-C2, PID2020-116786RB-C32] and the Spanish Ministry of Economy and Competitiveness [grant BES-2017-080326].

Stable L-band fiber laser sensor using a backscattering-based multimode fiber reflector

A new and highly stable L-band fiber laser for sensing is demonstrated. An emission line at 1575.47 nm, was achieved using a special reflector. Good strain sensitivity, optical signal to noise ratio and output power stability were measured.This work is part of the projects PID2019-107270RB-C02, funded by MCIN/AEI/10.13039/501100011033 and FEDER “A way to make Europe”, PDC2021-121172-C01 funded by MCIN/ AEI/10.13039/501100011033, the Ministerio de Educación, Cultura y Deporte of Spain (PhD grant FPU2018/02797), and European Union “Next generationEU”/PTR

共創サイクルを通じたリハビリ用具の開発と病院環境の改善

The project is students of non-experts in medical field cooperate with medical experts to develop a new products for rehabilitation care and they improve the hospital environment through collaboration cycles. The project obtained more knowledge and unique solution, in an interactive way, in the field of rehabilitation care and the problems in the hospital. The design proposals from the students served as an intervention in the context that they could be collaborated with the medical experts and users through collaboration cycles.departmental bulletin pape

New Silicate Phosphors for a White LED(<Special Section>Electronic Displays)

We focus on the development of new silicate phosphors for a white LED. In the europium doped silicate system, four LED phosphor candidates-Li_2SrSiO_4:Eu^, Ba_9Sc_2Si_6O_:Eu^, Ca_3Si_2O_7:Eu^ and Ba_2MgSi_2O_7:Eu^ were found. Luminescent properties under near UV and visible excitation were investigated for the new Eu^ doped LED silicate phosphors. These new phosphors have a relatively strong absorption band in a long wavelength region.journal articl
