Bird species diversity in the Atlantic Forest of Brazil is not explained by the Mid-domain Effect

Zoologia (Curitiba), 2012
The Atlantic Forest is an excellent case study for the elevational diversity of birds, and some inventories along elevational gradients have been carried out in Brazil.

The Z-Axis: Elevation Gradient Effects in Urban America [PDF]

SSRN Electronic Journal, 2016
Abstract This paper presents an in-depth analysis of hilliness effects in American urban communities. Using data from seventeen cities, we establish robust relationships between topography and density, income and housing value gradients. We find that high-income households display strong preference not only for higher altitude but also for unevenness,

Possible Transmitral Pressure Gradient Elevation in MitraClip XTR

Canadian Journal of Cardiology, 2019
A 74-year-old man presented with dyspnea due to severe mitral regurgitation (MR) caused by rupture of the chordae tendineae. Percutaneous edge-to-edge mitral valve repair was performed using the MitraClip system (Abbott Vascular, Santa Clara, CA). After leaflet grasping via an XTR clip, transesophageal echocardiography (TEE) revealed marked reduction ...

Ant Diversity Declines with Increasing Elevation along the Udzungwa Mountains, Tanzania

Diversity, 2022
Biodiversity patterns along elevational gradients are generally characterised by monotonic decreases or mid-elevational peaks in species richness, while elevational zones may be characterised by distinct assemblages, or higher zones may be subsets of ...

Predictors of elevational biodiversity gradients change from single taxa to the multi-taxa community level [PDF]

, 2016
The factors determining gradients of biodiversity are a fundamental yet unresolved topic in ecology. While diversity gradients have been analysed for numerous single taxa, progress towards general explanatory models has been hampered by limitations in ...

Functional traits of a plant species fingerprint ecosystem productivity along broad elevational gradients in the Himalayas [Dataset]

, 2023
To respect the intellectual property rights, protect the rights of data authors, expand services of the data center, and evaluate the application potential of data, data users should clearly indicate the source of the data and the author of the data in ...

The patterns and causes of elevational diversity gradients

Ecography, 2012
A major focus of research in spatial ecology over the past 25 years has been to understand why the number of species varies geographically. ! e most striking, and perhaps best documented, pattern in spatial ecology is the latitudinal gradient in species diversity in which the number of species, for most taxa, declines with increasing latitude ...

Elevation gradient of soil bacterial communities in bamboo plantations [PDF]

Botanical Studies, 2016
Elevation trends of macro organisms have long been well studied. However, whether microbes also exhibit such patterns of elevation change is unknown. Here, we investigated the changes in bamboo forest soil bacterial communities along six elevation gradients, from 600 to 1800 m a.s.l. in Mt.

Elevational changes in insect herbivory on woody plants in six mountain ranges of temperate Eurasia: Sources of variation

Ecology and Evolution, 2022
Current theory predicts that the intensity of biotic interactions, particularly herbivory, decreases with increasing latitude and elevation. However, recent studies have revealed substantial variation in both the latitudinal and elevational patterns of ...

Spatial prediction of plant species richness and density in high-altitude forests of Indian west Himalaya

Trees, Forests and People, 2021
The spatial distributions of plant species are results of variable environmental gradients, including climatic and edaphic factors, biotic factors, different eco-physiological processes, species-specific characteristics, and resource requirements, thus ...
