Evaluating anisotropy‐based Monin–Obukhov similarity theory over canopies and complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study shows that an anisotropy‐based generalization of Monin–Obukhov surface‐layer scaling (SC23) applies readily across a wide range of atmospheric conditions with variable terrain, canopies, and land‐cover complexity. This work focuses on the scaling of velocity variances for 7 years at the 47 sites in the National Ecological Observation Network

Tourism as a Catalyst for Blue Carbon Restoration and Conservation: Pathways, Gaps, and Opportunities

Sustainable Development, EarlyView.
ABSTRACT Tourism is a major driver of coastal economies worldwide, yet it is also a growing source of pressure on blue carbon ecosystems (BCEs) such as mangroves, seagrasses, and salt marshes. Nowadays, tourism‐led conservation/restoration is increasingly promoted under the banner of regenerative tourism, but how these projects are motivated ...

Characteristics of water dissolved organic matter in Zoige alpine wetlands, China

Chemical and Biological Technologies in Agriculture
Background Dissolved organic matter (DOM) plays a significant role in the biogeochemical cycle of crucial elements in aquatic ecosystem. However, it is still not clear on the spectral characteristics of water DOM in different types of alpine wetlands ...

The evolution of hummock–depression micro‐topography in an alpine marshy wetland in Sanjiangyuan as inferred from vegetation and soil characteristics

Ecology and Evolution, 2021
The hummock–depression micro‐topography characteristics of the alpine marshy wetland in Sanjiangyuan are indicative of wetland degradation and the process by which healthy wetlands are transformed into flat grasslands. The aim of the present study was to

Changes in alpine wetland ecosystems of the Qinghai–Tibetan plateau from 1967 to 2004 [PDF]

Environmental Monitoring and Assessment, 2010
Spatiotemporal shifts in the extent and distribution of alpine wetland ecosystems in China's Qinghai-Tibet plateau were investigated for the period 1967-2004. Using aerial photographs for 1967, and satellite remote sensing data for 1986, 2000, and 2004/5, the main components and distribution of alpine wetland ecosystems in the headwaters regions of the

A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

Wildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

The spatial differentiation of alpine wetlands on the eastern Tibetan Plateau using multi-source remote sensing images

Frontiers in Remote Sensing
The alpine wetlands on the eastern Qinghai-Tibet Plateau (EQTP) serve as a critical global ecological barrier. Under the dual pressures of climate change and human activities, these wetland systems face environmental challenges such as retrogressive ...

A literature‐based framework for anticipating golden jackal Canis aureus colonisation: insights from Europe and a Swiss case study

Wildlife Biology, EarlyView.
The expansion of the golden jackal Canis aureus in Europe, caused mainly by habitat fragmentation, climate change and the decline of large carnivores until half a century ago, poses emerging challenges for newly colonised regions. With the arrival of a new species, potential effects on local animal communities, hunting, livestock husbandry or the ...

Asymmetric niche partitioning in large omnivores in response to anthropogenic disturbances within subarctic ecosystems

Journal of Animal Ecology, EarlyView.
Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,
