Acclimatization. Acclimatization or acclimatisation (also called acclimation or acclimatation) is the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain fitness across a range of environmental conditions.
Mesophytes are terrestrial plants which are adapted to neither particularly dry nor particularly wet environments. An example of a mesophytic habitat would be a rural temperate meadow, which might contain goldenrod, clover, oxeye daisy, and Rosa multiflora. Mesophytes prefer soil and air of moderate humidity and avoid soil with standing water ...
Organisms at high altitude. An Alpine chough in flight at 3,901 m (12,799 ft) Organisms can live at high altitude, either on land, in water, or while flying. Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes.
Evolutionary history of plants. A late Silurian sporangium, artificially colored. Green: A spore tetrad. Blue: A spore bearing a trilete mark – the Y -shaped scar. The spores are about 30–35 μm across. The evolution of plants has been resulted in a wide range of complexity, from the earliest algal mats of unicellular archaeplastids evolved ...
Desert ecology is the study of interactions between both biotic and abiotic components of desert environments. A desert ecosystem is defined by interactions between organisms, the climate in which they live, and any other non-living influences on the habitat. Deserts are arid regions that are generally associated with warm temperatures; however ...
A cactus (pl.: cacti, cactuses, or less commonly, cactus) [3] is a member of the plant family Cactaceae (/ kækˈteɪsi.iː, - ˌaɪ /), [a] a family comprising about 127 genera with some 1,750 known species of the order Caryophyllales. [4] The word cactus derives, through Latin, from the Ancient Greek word κάκτος (káktos), a name ...
In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. [ 1 ] Spores form part of the life cycles of many plants, algae, fungi and protozoa. [ 2 ]
In such climates, there is a predominance of conifers because few evergreen broadleaf plants can tolerate severe cold below about −26 °C (−15 °F). [clarification needed] [citation needed] In areas where there is a reason for being deciduous, e.g. a cold season or dry season, evergreen plants are usually an adaptation of low nutrient levels.
