Grazing potentially alters grassland ecosystem carbon (C) and nitrogen (N) storage and cycles, however, the overall direction and magnitude of such alterations are poorly understood on the Northern Great Plains (NGP). By synthesizing data from multiple studies on grazed NGP ecosystems, we quantified the response of 30 variables to C and N pools and fluxes to grazing using a comprehensive meta-analysis method. Results showed that grazing enhanced soil C (5.2 ± 4.6% relative) and N (11.3 ± 9.1%) pools in the top layer, stimulated litter decomposition (26.8 ± 18.4%) and soil N mineralization (22.3 ± 18.4%) and enhanced soil NH4(+) (51.5 ± 42.9%) and NO3(-) (47.5 ± 20.7%) concentrations. Our results indicate that the NGP grasslands have sequestered C and N in the past 70 to 80 years, recovering C and N lost during a period of widespread grassland deterioration that occurred in the first half of the 20(th) century. Sustainable grazing management employed after this deterioration has acted as a critical factor for C and N amelioration of degraded NGP grasslands and about 5.84 Mg C ha(-1) CO2-equivalent of anthropogenic CO2 emissions has been offset by these grassland soils.

Structure-Activity Relationships for s-Block Metal/Co(III) Heterodinuclear Catalysts in Cyclohexene Oxide Ring-Opening Copolymerizations.

In homogeneous catalysis, uncovering structure-activity relationships remains very rare but invaluable to understand and rationally improve performances. Here, generalizable structure-activity relationships apply to a series of heterodinuclear polymerization catalysts featuring Co(III) and s-block metals M(I/II) (M= Na(I), K(I), Ca(II), Sr(II), Ba(II)). These are shown to apply to polycarbonate production by the ring-opening copolymerizations (ROCOP) of cyclohexene oxide (CHO) and carbon dioxide (CO2), conducted at high (20 bar) and low (1 bar) CO2 pressures, and to polyester production by copolymerization of cyclohexene oxide and phthalic anhydride (PA).

Introduction: Eleutherine bulbosa (Miller) Urb, popularly known as "marupa-zinho", is frequently used in traditional medicine for treating various diseases, including hypertension, ulcers, constipation, and intestinal infection. However, there is little scientific knowledge available regarding the pharmacological effects of this species. Thus in vivo and in silico phytochemical studies are required to establish whether this plant has these effects.

Understanding how TiO2 interacts with CO2 at the molecular level is crucial in the CO2 reduction toward value-added energy sources. Here, we report in-situ observations of the CO2 activation process on the reduced TiO2(110) surface at room temperature using ambient pressure scanning tunneling microscopy. We found that oxygen vacancies (Vo) diffuse dynamically along the bridging oxygen (Obr) rows of the TiO2(110) surface under ambient CO2(g) environments.

Article Synopsis
- The aye-aye is a rare nocturnal lemur from Madagascar, making it challenging to accurately assess its population size using traditional methods.
- Recent genomic data from 17 individual aye-ayes have been used to better understand their population history, revealing a separation into two distinct groups on the island.
- The study highlights two significant population declines: one around 3,000-5,000 years ago linked to human arrival and another recent decline due to habitat loss, indicating an ongoing risk of extinction for the species.
