silvicultural operation need to notice the plant species diversity in forest. to this study gomarlang district in marivan region, northern zagros forest was selected. selected 100 ha area because have similar physiography condition (north aspect and 1650 to 1800 m s.a.l. in study area 100 micro plots of 5m by 5 m (25 m2) including the species and the numbers of this species randomized-systemati...

Plant interactions greatly affect plant community structure. Dryland ecosystems are characterized by low amounts of unpredictable precipitation as well as by often having biological soil crusts (BSCs) on the soil surface. In dryland plant communities, plants interact mostly as they compete for water resources, and the direction and intensity of plant interaction varies as a function of the temp...

for assessment and comparison of measuring density methods of festuca ovina, bromus tomentellus and prangos ferulacea, three plants communities are selected. in all of plant community, reference area was defined and samples 7000 (70*100) square meter was selected. whole the area, sampling was accumplished as systematic-random. in each area, 5 transect 100 meter are established. then in areas 70...

Herbivores are important drivers of plant species coexistence and community assembly. However, detailed mechanistic information on how herbivores affect dominance hierarchies between plant species is scarce. Here, we used data of a multi-site herbivore exclusion experiment in grasslands to assess changes in the cover of 28 plant species in response to aboveground pesticide. application. Moreove...

fire is one of the most important ecological factors in semi-steppe rangelands directing plant community composition, diversity, structure and function of ecosystems. our primary aim was to examine the effect of fire on plant community composition, diversity, plant species restoration and animal selectivity in semi-steppe rangeland in karsanak region, chaharmahal & bakhtiari province in years 2...

during the past decade, natural plant products as environmentally safe option have received attention for controlling phytopathogenic diseases. investigation of plants containing natural antimicrobial metabolites for plant protection has been recognized as a desirable method of disease control. the fungus fusarium oxysporum causes diseases such as root rot, damping off and fusarium wilt and it ...
