Traditionally, methane (CH4) emission from terrestrial plants is thought to originate from belowground microbial metabolism under anaerobic conditions, with subsequent transport to the atmosphere through stems. However, a recent study reported aerobic CH4 emission from plants by an unrecognized process, a result that has since been questioned. We investigated CH4 emissions under aerobic conditi...

vetiver grass is known to survive under diverse soil and water conditions. in order to test its potential of salinity and aridity tolerance ability, the effect of salinity and aridity stress on the growth of the vetiveria zizanioides was studied by growing plants in arid soils that receiving salinity stress. the experiment was conducted in a greenhouse, arrangement in a completely randomized de...

Drought-tolerant plants, also called xerophytes, have developed during evolution a huge spectrum of morphological, physiological and metabolic adaptations to a shortage of water. Due to global climate change large areas of land are threatened by increasing water limitation and therefore drought stress. In addition, energy becomes limiting for an increasing world population and renewable local e...

Eight Pleistocene wood rat middens at elevations of 1200, 880, and 600 meters in the Chihuahuan Desert contain abundant macrofossils of pinyon pine, juniper, shrubby liveoak, and Opuntia, together with smaller quantities of Agave lecheguilla and other xerophytes of existing desert vegetation, which in dicate a xerophilous woodland vegetation in the lowlands, as much as 800 meters below existing...

With over 1,000 species, Pteridaceae comprises approximately 10% of extant fern diversity and is notable for its extreme morphological and ecological disparity. In addition to species-rich and predominantly forest-dwelling genera such as Adiantum and Pteris, the family includes floating, freshwater aquatics (Ceratopteris), mangrove specialists (Acrostichum), obligate epiphytes (Vittaria), and e...
