Seasonal wetlands in the tropics are important habitats for local and migratory bird species. In northwestern Pacific of Costa Rica, Palo Verde National Park has one most seasonal Central America. The management history this wetland shown impact invasive plant species such as Parkinsonia aculeata L. whose cover extension canopy structure not only ecological niches species, but also hydrology. A...

The monophyly of the Peltophorum group, one of nine informal groups recognized by Polhill in the Caesalpinieae, was tested using sequence data from the trnL-F, rbcL, and rps16 regions of the chloroplast genome. Exemplars were included from all 16 genera of the Peltophorum group, and from 15 genera representing seven of the other eight informal groups in the tribe. The data were analyzed separat...

Fabaceae (leguminous species) is the third-largest family of angiosperms. Floristical and vegetation analysis studies of wild leguminous species in Taif, Saudi Arabia were the prime aims of the current work. General survey of the studied area resulted to the selection of three different locations (Alshafa area (with its different habitats), Wadi seesed and Taif Hawia road (cutting many small wa...

Plants can vary substantially among species in morphological and physiological traits that influence their resistance to herbivores and their quality for herbivore growth and development. Seeds of the desert trees Cercidium floridum and C. microphyllum vary within and among populations in their resistance to, and suitability for, growth and development of larvae of the seed beetle, Stator limba...

Seeds of many arid habitat plants have a water-impermeable coat and can germinate only after being scarified. Bruchine seed beetles are important parasites of legume seeds in these environments, but their effect on germination can be unpredictable. Beetles deplete seed resources and can kill the embryo but also scarify seeds. We investigated the effects of a generalist parasite, Stator limbatus...

Abstract Crop losses due to pathogen attacks had increased tremendously from year and this situation is very alarming. Among important pathogen, fungi are dominant causal agents of plant disease that manage colonize the host with various strategies finally kill them. Identification based on laboratory investigations become vital since there many kinds linked disease. Laboratory might take a lon...
