From Bees to Flies: Global Shift in Pollinator Communities Along Elevation Gradients

open access: yesFrontiers in Ecology and Evolution, 2021
Bees decrease in abundance and richness along elevation gradients, while flies replace bees as the dominant flower visitors in higher elevation systems. We reviewed the existing literature to determine if this global phenomenon of pollinator communities ...

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

open access: yesBotanical 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.

Data from: Environmental variation associated with topography explains butterfly diversity along a tropical elevation gradient

open access: yes, 2021
Few studies have evaluated the role of topography on the diversity patterns of biological communities along elevation gradients. We evaluated the influence of microclimate and vegetation structure associated with topographic variation on the richness and

Effects of topographic factors on distribution of cacti along an elevation gradient in Brazilian Caatinga

open access: yesRodriguésia, 2021
The Cactacea family comprises 128 genera and 1450 species with predominantly neotropical distribution. Cacti are commonly found in arid and semi-arid regions and have great ecological relevance due to their interactions with animals and other groups of ...

Global patterns of protection of elevational gradients in mountain ranges [PDF]

open access: yesProceedings of the National Academy of Sciences, 2018
Significance Mountain ranges constitute biodiversity hotspots, and montane species are shifting their ranges in elevation in response to climate change. Protecting elevational gradients can help fully capture montane biodiversity patterns and facilitate species range shifts.

Multibaseline Gradient Ambiguity Resolution To Support Minimum Cost Flow Phase Unwrapping [PDF]

open access: yes, 2010
The TanDEM-X Mission has as primary objective to generate a high resolution global Digital Elevation Model. This paper proposes a new method for multibaseline Phase Unwrapping which is the critical point of this generation.

Subaortic Stenosis With Elevated Aortic Gradients in a Pregnant Patient

open access: yesJACC: Case Reports, 2020
Subaortic stenosis is an obstructive lesion that may be exacerbated by pregnancy. We describe the management of a 39-year-old woman presenting at 37 weeks of pregnancy with a murmur who is found to have a subaortic membrane with severely elevated left ventricular outflow gradients. (Level of Difficulty: Beginner.).

Temporal variation and climate dependence of soil respiration and its components along a 3000 m altitudinal tropical forest gradient [PDF]

open access: yes, 2010
To simulate the effect of temperature on soil respiration rates, we translocated soil cores among four sites (3030, 1500, 1000, and 200 m asl) along an altitudinal tropical forest gradient in the Peruvian Andes, traversing a difference in mean annual ...

Features and driving factors of microbial metabolic limitation in mountain ecosystems in arid areas: A case study on the Helan Mountains, Northwest China

open access: yesFrontiers in Forests and Global Change, 2022
Insights into what limits the growth of soil microorganisms in mountain ecosystems increase our understanding of microbial functions and processes. Although the distribution pattern of soil microorganisms in mountain ecosystems has been widely studied ...

Contrasting roles of fungal necromass and mineral preservation in influencing mineral-associated organic carbon across and within elevation bands

open access: yesFrontiers in Microbiology
Mineral-associated organic carbon (MAOC) is a persistent fraction of soil organic carbon (SOC) that is central to long-term carbon (C) persistence and climate mitigation.
