Cultivated Elionurus muticus (Spreng.) Kunth (Gramineae) plant parts were steam distilled for essential oil and evaluated in-vitro for antifungal activity against Candida albicans, C. krusei and Cryptococcus neoformans using agar broth dilution and disc diffusion methods and the activity compared with commercial citral and Cymbopogon citratus DC (Stapf) (lemongrass) oils by measuring the growth...

pistacia atlantica subsp. mutica is one of the most valuable forest tree species in iran that has been severely exploited for a long time. therefore, understanding the genetic diversity of different populations can be an important step towards the development and restoration of the habitat of this invaluable tree species. in this study, in order to study the genetic diversity, 10 populations in...

Threatened species often exist in a small number of isolated subpopulations. Given limitations on conservation spending, managers must choose from strategies that range from managing just one subpopulation and risking all other subpopulations to managing all subpopulations equally and poorly, thereby risking the loss of all subpopulations. We took an economic approach to this problem in an effo...

We investigated the effectiveness of a coyote (Canis latrans) control program implemented to increase numbers of endangered San Joaquin kit foxes (Vulpes macrotis mutica) at the Naval Petroleum Reserves in California (NPRC). Between 1980 and 1985, the kit fox population on NPRC declined approximately 66% while coyote abundance apparently increased. Coyote predation was identified as the primary...
