During the past decade, as the issue of plant invasion gained recognition in the public domain, both ecologists and weed scientists voluntarily or by mandate moved to provide their expertise to the management of invasive plants on public lands. Diverse views of nature carried to the table by ecologists and weed scientists have resulted in different priorities and opinions on management strategi...

Oxalis pes-caprae f. pleniflora (Lowe) Sunding (Oxalidaceae), a naturalized invasive alien is recorded for the first time from Turkey. It has staminodes and double petals as different properties from Oxalis pes-caprae L. Sympatric variations occured in the species populations could be the result of an accumulation of mutations or genome rearrangement. Invasive alien weed Oxalis pes-caprae and i...

Ten insect species were introduced to control five weeds on the island of Mauritius from 1914 to1982. Eight of these (80%) became established. The biocontrol programs against Opuntia vulgaris, O. tuna and Cordia curassavica were completely successful, with all three target plants now not considered as weeds, and requiring no management other than the ongoing, self-sustaining biological control....

Evolutionary algorithms have been recognized to be suitable for extracting approximate solutions of multi-objective problems because of their capability to evolve a set of non-dominated solutions distributed along the Pareto frontier‎. ‎This paper applies an evolutionary optimization scheme‎, ‎inspired by Multi-objective Invasive Weed Optimization (MOIWO) and Non-dominated Sorting (NS) strategi...

Mesquite is an invasive and problematic weed in warm and dry areas and so its management is very important. In order to study the effective factors on mesquite seed germination, the following studies were conducted to investigate: 1- seed viability; 2- the effect of constant temperatures on seed germination including 5, 10, 15, 20, 25, 30, 35 and 40°C independent dark and independent light ...

Parthenium hysterophorus L., (Asteraceae) commonly known as parthenium weed, is a highly invasive plant that has become a problematic weed of pasture lands in Australia and many other countries around the world. For the management of this weed, an integrated approach comprising biological control and plant competition strategies was tested in southern central Queensland. Two competitive pasture...

الگوریتم فراابتکاری علف های هرز یکی از الگوریتم های بهینه سازی جدید و توانمند است که بر اساس تقلید از قابلیت تطابق پذیری و تصادفی بودن کولونی علف های هرز، بهینه عمومی یک تابع ریاضی را پیدا می کند. تاکنون بررسی مدونی در خصوص تاثیر پارامترهای این الگوریتم بر عملکرد آن (کیفیت جواب و زمان محاسباتی) انجام نشده است. بعلاوه عملکرد الگوریتم علف های هرز در حل مسائل برنامه ریزی تولید تا به حال بررسی نگرد...

Invasive plants reduce the capacity of ecosystems to provide goods and services required by society, alter ecological processes, and can displace desirable species. They can reduce wildlife habitat quality, riparian area integrity, rangeland economic value, and enterprise net returns. The invasion process is regulated by characteristics of the invading plant and the community being invaded. The...
