Phenology of aquatic macroinvertebrates in an alpine wetland

Hydrobiologia, 1996
The temporal distribution of populations of aquatic macroinvertebrates have been extensively investigated in temperate arctic regions, but little information is available for alpine regions in North America. This paper describes phenology patterns of the aquatic macroinvertebrates of a high elevation wetland (3593 m) in the Green Lakes Valley, Colorado

Alpine wetlands in the Lhasa River Basin, China

Journal of Geographical Sciences, 2010
The Lhasa River Basin is one of the typical distribution regions of alpine wetlands on the Tibetan Plateau. It is very important to get a better understanding of the background and characteristics of alpine wetland for monitoring, protection and utilization.

Water chemistry and periphyton in an alpine wetland

Hydrobiologia, 1995
Remote high elevation sites are thought to be good sites to monitor global change and anthropogenic effects on ecosystems. This study was conducted during 1987–1990 in a high elevation wetland (3593 m) located in the Green Lakes Valley, Front Range, Colorado (USA). Salix spp. was the dominant riparian species in this 2 ha. wetland. Small shallow pools (

Spectral features and separability of alpine wetland grass species

Spectroscopy Letters, 2016
ABSTRACTThis study aimed to analyze the spectral features of alpine wetland grasses and evaluate three types of spectral feature computational methods. In situ spectra of alpine wetland grasses were collected in the northeastern Qinghai–Tibetan Plateau (Niaodao Wetland of International Importance and Ruoergai Wetland of International Importance), and ...

Morphological plasticity of Primula nutans to hummock-and-hollow microsites in an alpine wetland

Journal of Plant Research, 2006
Hummock-and-hollow microtopography is common in wetlands of the Qinghai-Tibetan Plateau. The physical environment of hummocks contrasts strongly with that of hollows. To address how Primula nutans Georgi, a herbaceous species broadly distributed on the plateau, can inhabit both hummocks and hollows, we investigated the plasticity of its morphology and ...

Analysis of fungal community structure in the soil of Zoige Alpine Wetland

Acta Ecologica Sinica, 2009
Abstract To understand the soil fungal community diversity in different zones of the Zoige Alpine Wetland, BIOLOG analysis and traditional culture method were employed in our research. Three sample sites namely the Conservatory Station up-hill slope (CSUS), the Flower Lake side (FLS) and the Conservatory Station down slope (CSDS) with increasing by ...

Investigation of bacterial community diversity in water of Zoige Alpine Wetland

Acta Ecologica Sinica, 2011
Abstract Spatial isolation is currently thought to represent one of the major factors resulting in bacteria genetic variation and population abundance. The bacterial diversity in a distinct environment Zoige Alpine Wetland located in the northeast of the Qinghai-Tibetan Plateau with the altitude 3400 m on average aroused our great attention.

[Research on algal diversity in Zoige Alpine Wetland].

Huan jing ke xue= Huanjing kexue, 2013
Water samples were collected in summer and winter in Zoige Alpine Wetland. Both the traditional cultivable and microscopic method and modern molecular approach were used to reveal the algal diversity in the wetland. For the samples collected in summer, single-cell Chlorophyta was cultured, isolated and identified.

Annual methane emissions from degraded alpine wetlands in the eastern Tibetan Plateau

Science of The Total Environment, 2019
Grazing-oriented drainage of alpine/boreal wetlands has been broadly implemented to meet the increasing demand for animal products. However, the annual methane (CH4) emissions from alpine fens degraded due to drainage for grazing have not been well characterized due to a lack of year-round observations.

[Impact of Alpine Wetland Succession to Soil Bacterial Diversity].

Huan jing ke xue= Huanjing kexue
This study aims to explore the characteristics of change and the rules of response of the soil bacterial community structure and diversity during the evolution of alpine wetlands. It also seeks to identify the leading factors affecting changes in the soil bacterial community, with the goal of providing a scientific basis for the restoration and ...
