Ecological convergence of secondary phytochemicals along elevation gradients
New Phytologist, 2020 Biologists still strive to identify the ecological and evolutionary drivers of phytochemical variation that mediates biotic interactions. We hypothesized that plant species growing at sites characterized by high herbivore pressure would converge to produce highly toxic blends of secondary metabolites, independently of phylogenetic constraints.

Diversity Patterns of Dung Beetles along a Mediterranean Elevational Gradient [PDF]
Insects, 2021 Most studies of biodiversity–elevational patterns do not take species abundance into consideration. Hill numbers are a unified family of indices that use species abundance and allow a complete characterization of species assemblages through diversity profiles.

Elevation puts moral values into action [PDF]
, 2010 Moral elevation has been shown to increase helping behavior. However, this might be due to a threatened moral self-image because people engage in a social comparison with a moral exemplar and conclude that their own moral integrity is inferior ...

Sensitivity of GNSS tropospheric gradients to processing options [PDF]
Annales Geophysicae, 2019 An analysis of processing settings impacts on estimated tropospheric gradients is presented. The study is based on the benchmark data set collected within the COST GNSS4SWEC action with observations from 430 Global Navigation Satellite Systems (GNSS ...

Palustrine forested wetland vegetation communities change across an elevation gradient, Washington State, USA [PDF]
PeerJ, 2020 Background Forested wetlands support distinct vegetation and hydrology relative to upland forests and shrub-dominated or open water wetlands. Although forested wetland plant communities comprise unique habitats, these ecosystems’ community structure is ...

Alpine grassland soils contain large proportion of labile carbon but indicate long turnover times [PDF]
, 2011 Alpine soils are expected to contain large amounts of labile carbon (C) which may become a further source of atmospheric carbon dioxide (CO2) as a result of global warming.

Local plant adaptation across a subarctic elevational gradient [PDF]
Royal Society Open Science, 2014 Predicting how plants will respond to global warming necessitates understanding of local plant adaptation to temperature. Temperature may exert selective effects on plants directly, and also indirectly through environmental factors that covary with temperature, notably soil properties.

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,
