Celtis australis is an important agroforestry tree in the Himalayan region providing major fodder to livestock and many other needs for sustaining life local rural communities. Including their value wide altitudinal distribution ranges, it extracted by villagers large scale during lean period (May June). Thus, aim was understand nutritive values of species influenced altitude harvesting season....

Abstract Using the electron density profiles from Mars Global Surveyor Radio Occultation observations, ionospheric longitudinal wave‐3 (WN3) structure with different frequencies is investigated. The semidiurnal component dominant for entire ionosphere profile at northern high latitudes. Both diurnal and components manifest double peaks in altitudinal variations amplitude, which are 5–15 km lowe...

We examined stand dynamics and biomass along an altitudinal gradient in a tropical montane forest (TMF) in the disturbance-prone Cordillera Central, Dominican Republic. We tested the general hypothesis that chronic disturbance by fire, wind, floods and landslides results in a landscape of relatively low above-ground biomass with high rates of mortality, recruitment and growth as compared with o...

Altitudinal migrations are common in all major vertebrate and some invertebrate lineages. Such migrations have important implications for the basic and applied ecology of animals making these movements. The idea that bats make altitudinal migrations has been suggested for nearly a century. However, studies documenting the existence and causes of altitudinal bat migrations are scarce, and are fr...

Abstract Variation in genome size and knob heterochromatin content was explored relationship to altitudinal cline length of the vegetative cycle northern Argentina, USA Mexico landraces. It considering that decrease DNA could be an adaptation a shorter growing season result artificial selection by man. Guaraní landraces from Northeastern Argentina (NEA) show similar variation (3.81pg 7.56pg) th...
