Grasslands are crucial ecosystem biomes for breeding livestock and combatting climate change. By 2018, the national nature reserves (NNRs) in Inner Mongolia Autonomous Region (IMAR) had constituted 8.55% of land area. However, there is still a knowledge gap about their effectiveness grasslands. Based on multiyear time series growing season composite from 2000 to 2020, we proposed an score asses...
Conservation reserves are a fundamental tool for managing biodiversity. The so-called SLOSS debate--should we have a Single Large Or Several Small reserves - is central to conservation theory. Population dynamic models suggest that the design that minimizes the risk of extinction of a species is case-specific, with the optimal number of reserves ranging between one and very many. Uncertainty is...
The Vietnamese government has introduced co-management in its national system of special-use forests (SUFs) to improve the effectiveness of nature and biodiversity conservation. One of the major challenges is to allow flexibility and local adaptability of co-management coordinated by SUF management boards within the overall still-rigid structure of vertical state networks. Using a critical inst...
Persistent global urbanization has a direct relationship to measurable artificial light at night (ALAN), and the Defense Meteorological Satellite Program served an important role in monitoring this over time. Recent studies have observed significant declines insect abundance populations, ALAN been recognized as contributing factor. We investigated changes nightlight intensity various spatial sc...
It is notable that over the past decade, proven reserves of natural gas have dramatically increased as higher prices and advances in technology have turned previously unrecoverable resources into major sources of domestic production. Moreover, the decline in crude oil reserves has significantly slowed over the past decade. Therefore, there would be an end to the conventional hydrocarbon resourc...
BACKGROUND Zoning is a fundamental tool for the effective management of nature reserves. A three-zone model (core zone, buffer zone, and experimental zone) has been applied to nature reserves in China since 1980s; however, this model appears not fit for all types of nature reserves, especially wetlands. CASE DESCRIPTION Wuliangsuhai is such a typical wetland reserve, which can represent most ...

Amphibians of 24 species were surveyed for acanthocephalans in 4 nature reserves in 2 Chinese provinces during 2004–2006. Pseudoacanthocephalus bufonis (Echinorhynchida) occurred in both nature reserves in Guangxi Province. In the Jing Xi County Provincial Nature Reserve, P. bufonis infected 36 of 62 amphibians at a mean intensity of 9.9. Less than 250 km away, at Shiwandashan National Nature R...
