Leaf Temperatures of Desert Plants

Science, 1968
Temperatures of small leaves of many desert plants are within 3° C of air temperature in contrast to the temperature of Opuntia in the same locale; this plant has a temperature 10° to 16° C above air temperature. Theoretical justification for the observation is given based on an energy budget analysis.

Anticancer attributes of desert plants

Anti-Cancer Drugs, 2012
The ever-increasing emergence of the resistance of mammalian tumor cells to chemotherapy and its severe side effects reduces the clinical efficacy of a large variety of anticancer agents that are currently in use. Thus, despite the significant progress in cancer therapeutics in the last decades, the need to discover and to develop new, alternative, or ...

Plant-soil interactions in deserts

Biogeochemistry, 1998
Geostatistical analyses show that the distribution of soil N, P and K is strongly associated with the presence of shrubs in desert habitats. Shrubs concentrate the biogeochemical cycle of these elements in ‘islands of fertility’ that are localized beneath their canopies, while adjacent barren, intershrub spaces are comparatively devoid of biotic ...

Rheum palaestinum (desert rhubarb), a self-irrigating desert plant

Naturwissenschaften, 2008
The rare plant Rheum palaestinum (Polygonaceae) is a perennial hemicryptophyte that grows during the rainy winter in desert mountainous areas in Israel and Jordan that receive an average annual rainfall of ca. 75 mm. It produces between one and four large round leaves that are tightly attached to the ground and form large rosettes of up to 1 m(2 ...

Pattern and mortality in Colorado Desert plants

Oecologia, 1987
We tested for intraspecific interference among Colorado Desert shrubs using an integrated analysis of spatial pattern and juvenile mortality. The data set included 7,000 woody perennials of 24 species in a mapped hectare of Joshua Tree National Monument, California.

Desert Plants Recognition by Bark Texture

2019 12th International Conference on Developments in eSystems Engineering (DeSE), 2019
Recognition of the desert plants is a challenging task for human as well as computers due to the similarities between these plants. We propose a novel method for recognizing of desert plants by the images of the bark. We extract the features of the texture of the bark using Weber Local Descriptor (WLD), we build a dataset of bark images for desert ...
