In this study, the effects of linoleic acid on the growth, photosynthetic activities and oxidative system of the invasive cyanobacterium Cylindrospermopsis raciborskii were investigated. The results indicated that linoleic acid decreased the growth rate and chlorophyll a concentration in C....

The effects of abiotic stresses (high and chilling temperatures, and drought) on woody (Acer negundo L., Fraxinus pennsylvanica Marsh.), and herbaceous [Conysa canadensis L., Echinocystis lobata (Michx.) Torr. et Gray] invasive plants have been assessed by establishing chlorophyll fluorescence...

Invasion by the exotic species Prosopis juliflora has become a major threat to native plants in Saudi Arabia as the species continues its spread into different regions of the country. Ziziphus spina-christi is a native tree that is common in Saudi Arabia. The objective of this study was to...

Weedy sunflower has become a problem worldwide, giving significant yield losses in sunflower and soybean fields even at low densities, decreasing their oil quality and allowing gene flow among crops and weeds. Its evolution differs among countries due to availability of wild forms. The problem is...

The introduction of omnivorous tilapia into a variety of aquatic systems worldwide has led to a number of serious ecological problems. One of the main issues is an increase in water turbidity, which affects not only light penetration but also primary production and the distribution of phytoplankton ...

To explore the effect of Galinsoga parviflora Cav., an invasive plant on seedling growth and photosynthetic physiological characteristics of broad bean (Vicia faba L.), the pot experiments were conducted to study the effects of plant heights, leaf areas, biomass, chlorophyll contents, chlorophyll...

Croftonweed originated from Mexico is a worldwide notorious invasive weed. The objectives of this study were to screen heat tolerance in different croftonweed populations, determine the effect of heat stress on two photosystems and probe the mechanism of acquired heat tolerance. According to...

The Ponto-Caspian amphipod Pontogammarus robustoides was introduced into Lithuanian inland waters more than 50 years ago and is now among the most successful local crustacean invaders. Existing as an oxyphilic species in its native range, in Lithuania it managed to establish in some lentic...

Acknowledged as among the worst invasive marine species, Mnemiopsis leidyi has spread through European Seas since the mid-1980's. Here we report a bimonthly survey conducted in 2010-11 in three lagoons (Bages-Sigean, Thau and Berre) and at two adjacent coastal stations (Sète and SOMLIT-Marseille)...

Weedy sunflower Helianthus annuus L. (WS) can become troublesome for cultivated sunflower given their genetic similarity which allows gene flow from weed-to-crop and from crop-to-weed. Also, it causes yield losses in different spring-sown crops. Despite this, there is still no data about its...
