The topmouth gudgeon Pseudorasbora parva is an eastern-Asian cyprinid species, which in relatively short time has colonised nearly the whole Europe. In some regions it has become a notable reproduction success and significantly disrupted native ecosystems. Such a fast expansion is most probably...

A study was conducted to determine whether infection by Cassytha pubescens could affect the growth and reproductive output of Cytisus scoparius. Regular observations over one season were made of flowering and consequent fruit and seed production of a field population of 40 Cytisus scoparius....

Koster's Curse (Clidemia hirta (L.) D. Don) is a highly invasive shrub which has the potential to become a major weed in many parts of Queensland and elsewhere in Australia. C. hirta is perennial, can grow to 5 m in height and mature plants are capable of producing in excess of 500 berries annually ...

Using published matrix population models for 21 invasive plant species with different life histories, we examined responsiveness to survival, growth and fecundity perturbations, and determined which life stages and demographic processes to target for the greatest reductions in population growth...

The reproduction and virulence of four Florida isolates of Meloidogyne mayaguensis to the root-knot nematode resistant ('Benning', 'Boggs', 'Bragg', 'Forrest', 'Haskell', 'Lee 74' and G-93-9009) and susceptible ('Bossier', 'GoSoy 17', 'Pickett') soybean genotypes were evaluated in a growth chamber. ...

Water hyacinth (Eichhornia crassipes Solms) is one of the most well-known invasive aquatic plants in the world In Thailand, apart from this species, there are plants species, which are gradually and steadily increasing their area of invasion, such as narrowleaf cattail (Typha angustifolia), Florida ...

The pathogenicity and reproductive potential of Meloidogyne mayaguensis and M. floridensis, two new species recently reported in Florida agriculture, were compared to those of M. arenaria race 1, M. incognita race 4, and M. javanica race 1 on tomato (Lycopersicon esculentum) in field microplots....

Chromolaena odorata is a perennial weed which invades forest areas cleared for developing plantations, nurseries, young plantations, and wastelands, but is conspicuously absent in the interior of dense forests or established plantations with closed canopy. The fresh seeds of C. odorata were found...

This supplement is comprised of the papers presented at the 2006 World Congress. It is divided into 28 parts. The topics covered include standards of care, controversies in alternative medicine, behaviour, cardiology and pulmonology, critical care and anaesthesiology, dermatology, dentistry,...
