Soil ammonia oxidizing bacteria (AOB) and archaea (AOA) are responsible for nitrification in terrestrial ecosystems, and play important roles in ecosystem functioning by modulating the rates of N losses to ground water and the atmosphere. Vascular plants have been shown to modulate the abundance of AOA and AOB in drylands, the largest biome on Earth. Like plants, biotic and abiotic features suc...

In this study, divided into three sites, forested site, fallow site current usage site. experiment laid a Randomized Complete Block Design. ecological methods used are Point Centred Plotless Count sam...

Carolina bays are depression wetlands of high conservation value that occur across the Southeastern Coastal Plain of the United States. Venus flytrap (Dionaea muscipula) is one rare carnivorous plant that grows in open habitats on the rims of Carolina bays. Without frequent burning, vegetation on bay rims becomes dominated by evergreen shrubs and Venus flytrap populations decline. This project ...

Halophytes are plants which naturally survive in saline environment. They account for ∼1% of the total flora of the world. They include both dicots and monocots and are distributed mainly in arid, semi-arid inlands and saline wet lands along the tropical and sub-tropical coasts. Salinity tolerance in halophytes depends on a set of ecological and physiological characteristics that allow them to ...

Specialty forages are those that do not have a wide application in animal production systems of Texas. Other than beef cattle, systems that use cultivated forage can be considered atypical in our state. These include white-tailed deer, game birds (quail or turkey), exotic game, goats, sheep, domesticated rabbits or any other species that is primarily an herbivore. These animals generally requir...

Late Quaternary histories of two North American desert biomesC4 grasslands and C3 shrublandsare poorly known despite their sensitivity and potential value in reconstructing summer rains and winter temperatures. Plant macrofossil assemblages from packrat midden series in the northern Chihuahuan Desert show that C4 grasses and annuals typical of desert grassland persisted near their present north...

Information on different rangeland plants’ nutritive values during variousphonological stages is of importance for the rangelands management. This information helpsrangeland managers to choose proper grazing times to achieve higher animal performancewith no detrimental effects on the rangeland vegetations. Effects of various plant parts’phenological stages and vegetation types on reserve carboh...

Florida’s dry prairies are rare and threatened due to suppression of natural fire regimes in these fire-dependent ecosystems. Ecological restoration of dry prairies reduces the growth of shrubs resulting from lack of fire, while encouraging the growth of grasses and forbs. In addition to prescribed burning, these efforts often use mechanical disturbance such as roller-chopping. In this study we...
