Positive interactions between alpine plant species and the nurse cushion plant Laretia acaulis do not increase with elevation in the Andes of central Chile
(BLACKWELL, 2006-01)
In alpine habitats, positive interactions among plants tend to increase with elevation as a result of altitudinal increase in environmental harshness. However, in mountains located in arid zones, lower elevations are also ...
Influence of the estrous cycle on the behavior of rats in the elevated T-maze
(Elsevier B.V., 2004-09-30)
The elevated T-maze is an animal anxiety model which can discriminate between anxiety-like and fear-like behaviors. The estrous cycle is an important variable of the response in animal anxiety tests and is known to affect ...

The upper range limit of alien plants is not in equilibrium with climate in the Andes of central Chile
(MDPI, 2022)
Alien plant species are colonizing high-elevation areas along roadsides. In this study, we evaluated whether the distributions of alien plants in the central Chilean mountains have reached climatic equilibrium (i.e., upper ...
DIGITAL ELEVATION MODEL VALIDATION WITH NO GROUND CONTROL: APPLICATION TO THE TOPODATA DEM IN BRAZIL
(Univ Federal Parana, Centro Politecnico, 2014-04-01)
Digital Elevation Model (DEM) validation is often carried out by comparing the data with a set of ground control points. However, the quality of a DEM can also be considered in terms of shape realism. Beyond visual analysis, ...
Is guava phenolic metabolism influenced by elevated atmospheric CO2?
(ElsevierOxford, 2014)
Seedlings of Psidium guajava cv. Pedro Sato were distributed into four open-top chambers: two with ambient CO2 (∼390 ppm) and two with elevated CO2 (∼780 ppm). Monthly, five individuals of each chamber were collected, ...
Leaf temperature of soybean grown under elevated CO2 increases Aphis glycines (Hemiptera: Aphididae) population growth
(Wiley Blackwell Publishing, Inc, 2011-08)
Abstract Plants grown under elevated carbon dioxide (CO2) experience physiological changes that influence their suitability as food for insects. To determine the effects of living on soybean (Glycine max Linnaeus) grown ...
Relationships between resource availability and elevation vary between metrics creating gradients of nutritional complexity
(2021-01-01)
Plant and animal community composition changes at higher elevations on mountains. Plant and animal species richness generally declines with elevation, but the shape of the relationship differs between taxa. There are several ...
Elevational differentiation in metabolic cold stress responses of an endemic mountain tree
(Elsevier, 2020-03)
The decline of mountain forests under global change is alarming and conservation is challenged by the need to assemble populations able to deal with the predicted environmental shifts. Assessing intraspecific differentiation ...
