Elevational diversity gradient (EDG) is an ecological pattern where biodiversity changes with elevation. The EDG states that species richness tends to decrease as elevation increases, up to a certain point, creating a "diversity bulge" at middle elevations.

Altitudinal zonation (or elevational zonation[1]) in mountainous regions describes the natural layering of ecosystems that occurs at distinct elevations due to varying environmental conditions.

2016年4月7日 · Our results indicate that the altitudinal pattern of plant and soil nutrient status differs among ecosystem components and that the relative importance of P vs. N limitation for ecosystem...

Altitudinal gradients reflecting steep changes in a wide range of abiotic and biotic variables are excellent systems for examining adaptive divergence and its maintenance between plant species. Such gradients are very common and available for investigation throughout large parts of …

2024年9月1日 · Here, we conducted a field investigation across altitudinal gradients (3093, 3296, 3549, and 3790 m) in the northern Tibetan Plateau and compared species composition, diversity indices, Levins' niche breadth, and Pianka's niche overlap.

The altitudinal gradient in biodiversity refers to the change in the diversity of plant and animal species observed along an altitude gradient. This phenomenon is characterized by a systematic variation in biodiversity due to changes in altitude, typically from sea level to …

2023年5月29日 · We compiled data from 118 studies of elevational gradients in a broad range of organisms of plant species throughout the world between 2001 and 2021 to estimate the patterns of species richness and their determinants.

2019年7月5日 · Here the relationship between vegetation activity and elevation is quantified as an elevational gradient (EG), which is defined as the average change of a vegetation activity index per 100 m...

2024年10月14日 · In mountainous or hilly terrain, the term “altitudinal gradient” describes a change in environmental parameters such as temperature, precipitation, and soil properties with increasing altitude. This gradient has a significant impact on …

2007年11月1日 · Altitudinal gradients are among the most powerful ‘natural experiments’ for testing ecological and evolutionary responses of biota to geophysical influences, such as low temperature.
