Snowmelt timing affects short‐term decomposition rates in an alpine snowbed

نویسندگان

چکیده

Alpine snowbed communities are characterized as having areas of longer lasting snow cover duration compared with the surrounding landscape. The predictable accumulation deep and long-lasting on lee side ridges drives a unique ecology, providing stable microclimatic conditions under through winter, supplying meltwater in spring, controlling many biological processes. timing rate plant litter decomposition key controls nutrient balance communities, thought to be strongly driven by dynamics. However, little is known about how patterns snowmelt affect decomposition, nor long these effects last into growing season. We investigated influence rates across an alpine community burying standardized (rooibos green tea), at three incubation times (whole year, winter+spring, summer), zones. Decomposition (as percent mass loss tea) was significantly higher early-melting zones late-melting zones, particularly for recalcitrant tea). also affected season(s) greatest where tea buried whole or only over summer, winter + spring incubations decomposing least. more influenced quality (type than either seasonality. These results provide further understanding changes may turn transform rare communities.

Experimental Evaluation of Seed Limitation in Alpine Snowbed Plants

BACKGROUND The distribution and abundance of plants is controlled by the availability of seeds and of sites suitable for establishment. The relative importance of these two constraints is still contentious and possibly varies among species and ecosystems. In alpine landscapes, the role of seed limitation has traditionally been neglected, and the role of abiotic gradients emphasized. METHODOLO...

Substantial compositional turnover of fungal communities in an alpine ridge-to-snowbed gradient.

The main gradient in vascular plant, bryophyte and lichen species composition in alpine areas, structured by the topographic gradient from wind-exposed ridges to snowbeds, has been extensively studied. Tolerance to environmental stress, resulting from wind abrasion and desiccation towards windswept ridges or reduced growing season due to prolonged snow cover towards snowbeds, is an important ec...

No increase in alpine snowbed productivity in response to experimental lengthening of the growing season.

Climate change effects on snow cover and thermic regime in alpine tundra might lead to a longer growing season, but could also increase risks to plants from spring frost events. Alpine snowbeds, i.e. alpine tundra from late snowmelt sites, might be particularly susceptible to such climatic changes. Snowbed communities were grown in large monoliths for two consecutive years, under different mani...

Solute Chemistry of Snowmelt and Runoff in an Alpine Basin, Sierra Nevada

Snowpack runoff contributions to the hydrochemistry of an alpine catchment in the Sierra Nevada were evaluated in 1986 and 1987 by analyzing snowpack, meltwater, and stream water samples for major inorganic ions, conductance, acid neutralizing capacity (ANC), and silicate. An ionic pulse in meltwater with initial concentrations twofold to twelvefold greater than the snowpack average, varying wi...

The Response of the Alpine Dwarf Shrub Salix herbacea to Altered Snowmelt Timing: Lessons from a Multi-Site Transplant Experiment

Climate change is altering spring snowmelt patterns in alpine and arctic ecosystems, and these changes may alter plant phenology, growth and reproduction. To predict how alpine plants respond to shifts in snowmelt timing, we need to understand trait plasticity, its effects on growth and reproduction, and the degree to which plants experience a home-site advantage. We tested how the common, long...
