Cultivable bacterial diversity along the altitudinal zonation and vegetation range of tropical Eastern Himalaya.
The Northeastern part of India sprawls over an area of 262 379km2 in the Eastern Himalayan range. This constitutes a biodiversity hotspot with high levels of biodiversity and endemism; unfortunately, is also a poorly known area, especially on its microbial diversity. In this study, we assessed cultivable soil bacterial diversity and distribution from lowlands to highlands (34 to 3 990m.a.s.l.)....
متن کاملAsymmetrical local adaptation of maize landraces along an altitudinal gradient
Crop landraces are managed populations that evolve in response to gene flow and selection. Cross-pollination among fields, seed sharing by farmers, and selection by management and environmental conditions play roles in shaping crop characteristics. We used common gardens to explore the local adaptation of maize (Zea mays ssp. mays) landrace populations from Chiapas, Mexico to altitude. We sowed...
متن کاملLeaf litter decomposition and microarthropod abundance along an altitudinal gradient
Mass loss rates of three types of leaf litter were measured along an altitudinal gradient at the Coweeta Hydrologic Laboratory, Macon County, North Carolina. Litterbags containing air dried litter from Quercus prinus L., Liriodendron tulipifera L., and Rhododendron maximum L. were placed in five plots along the gradient and sampled monthly. Microarthropods were extracted and sorted, and litter ...
متن کاملBehavioural tuning in a tropical amphibian along an altitudinal gradient.
Males of the coqui treefrog, Eleutherodactylus coqui, produce a distinct two-note 'co-qui' advertisement call from sunset to midnight throughout most of the year. Previous work established that both the spectrotemporal aspects of the call and the frequency of highest inner-ear sensitivity change with altitude above sea level. These variations are such that the frequency of the emitted co-note c...
متن کاملWarming effects on photosynthesis of subtropical tree species: a translocation experiment along an altitudinal gradient.
Ongoing climate warming induced by human activities may have great impacts on trees, yet it remains unresolved how subtropical tree species respond to rising temperature in the field. Here, we used downward translocation to investigate the effects of climate warming on leaf photosynthesis of six common tree species in subtropical China. During the experimental period between 2012 and 2014, the ...
