title: AmeriFlux AR-Bal Balcarce BA

description: This is the AmeriFlux version of the carbon flux data for the site AR-Bal Balcarce BA. Site Description - The study was carried out in a 19-ha rainfed soybean plot at the Unidad Integrada Balcarce, located southeast of Buenos Aires, Argentina. The site is located in an environment of gentle hills at 130 m.a.s.l. Its soil was classified as a typical Argiudoll, with a loamy clayey texture up to 0.30 m and between 0.80 to 1.10 m depth, and a clayey texture between 0.30 and 0.80 m depth. The slope was 1:50 and oriented NE to SW. A caliche layer was found at 1 to 1.2 m depth thus the water table was considered beneath that level. The soybean variety used was DM 3810, Maturity Group III with an indeterminate growing habit. It was sown on November 21, 2012, and emerged on December 1. The crop archive had a maximum height of 0.75 m.

title: AmeriFlux AR-Cel CELPA Mar Chiquita BA

description: This is the AmeriFlux version of the carbon flux data for the site AR-Cel CELPA Mar Chiquita BA. Site Description - The site is located at a mid-latitude South Atlantic pristine salt marsh. It occupies 43 km2 of an extended marginal flat surrounding a 25 km long brackish lagoon connected with the Argentine Sea through an inlet channel.  The small tide amplitude prevents extensive waterlogging with salt water. Unlike other Northern Hemisphere salt marshes regularly flooded by daily tides, Mar Chiquita soaks throughout the winter with approximately a 10 cm freshwater layer coming from rains, and during summer high temperatures and high evapotranspiration dry the soil, producing a thin salt crust on the surface. Another significant difference is that the canopy persists throughout the year without dying out, due to the lack of snowfall or below-freezing winter temperatures.

title: AmeriFlux BR-Sa1 Santarem-Km67-Primary Forest

description: This is the AmeriFlux version of the carbon flux data for the site BR-Sa1 Santarem-Km67-Primary Forest. Site Description - The LBA Tapajos KM67 Mature Forest site is a closed-canopy terra firme (upland) forest, located in the FLONA Tapajos, or National Forest, a 450,000 ha government conservation unit in the Brazilian Amazon. Bounded by the Tapajos River in the west and highway BR-163 to the east, the tower is located on a flat plateau (or planalto) that extends up to 40 km to the north, south, and east. The forest at the tower site is classified as primary or "old-growth"" predominantly by its uneven age distribution,  emergent trees,  numerous epiphytes and abundant large logs. In January 2006 and again in November 2023, falling trees hit the tower guy wires destroying the tower and halting measurements. In each case, the tower was restored and measurements resumed, first in August of 2008 (enabled by a Partnership for International Research and Education, or PIRE, grant from the U.S. National Science Foundation) and again in June 2024.

title: AmeriFlux CA-DB2 Delta Burns Bog 2

description: This is the AmeriFlux version of the carbon flux data for the site CA-DB2 Delta Burns Bog 2. Site Description - The Burns Bog Ecological Conservancy Area (BBECA) in the metro Vancouver area presents a unique opportunity for insight into greenhouse gas dynamics post restoration. The bog was significantly disturbed for peat mining, development and agriculture over the last century, however since 2005 there has been both active restoration and natural regeneration occurring within the bog. Hence areas of bog are at varying stages of ecological recovery. This site is a Pine-Sphagnum low shrub site characteristic of a later successional stage. Conversely, CA-DBB, another AmeriFlux site in BBECA, is a Beakrush-Sphagnum site characteristic of an earlier successional stage.

title: Regional integration and firm-level environmental performance

description: In the context of sustainable development, improving firm-level environmental performance is critical. However, the impact of regional integration on this performance remains intricate, as environmental outcomes vary significantly across different regions. This study explores how regional integration affects firm-level environmental performance, focusing on the role of relative environmental regulation. Using 130,727 industrial firm samples of 137 cities in 16 Chinese urban agglomerations from 2003 to 2009, this study measures firm-level environmental performance through the Kumbhakar-Lien-Hardaker Stochastic Frontier Analysis (KLH-SFA). Regional integration is quantified by a spatial division of labor index, and relative environmental regulation is assessed through a ratio of environmental governance intensity between core and peripheral cities. Results show regional integration positively influences environmental performance, but this effect is conditional on relative regulation. For core cities, the positive effect holds when relative regulation is below 1.464; beyond this, it turns negative. For peripheral cities, the threshold is 1.6. Relative regulation, local regulation stringency, and city size also independently boost environmental performance. Heterogeneity analyses reveal stronger effects for non-energy-intensive firms, non-state-owned enterprises, and in non-forming urban agglomerations. This study highlights that environmental gains from integration require coordinated intra-regional policies, emphasizing calibrated regulation to balance economic integration and sustainability.
