John D. Parker and Mark E. Hay* School of Biology, Georgia Institute of Technology, Atlanta, GA 30332–0230, USA *Correspondence: E-mail: [email protected] Abstract In contrast to expectations of the enemy release hypothesis, but consistent with the notion of biotic resistance, we found that native generalist crayfishes preferred exotic over native freshwater plants by a 3 : 1 ratio wh...

The flammability of plant leaves influences the spread of fire through vegetation. Exotic plants invading native vegetation may increase the spread of bushfires if their leaves are more flammable than native leaves. We compared fresh-leaf and dry-leaf flammability (time to ignition) between 52 native and 27 exotic plant species inhabiting dry sclerophyll forest. We found that mean time to ignit...

Hygienic and grooming behaviors of native and exotic honeybee races reared in Riyadh, Saudi Arabia were investigated. Both races exhibited different rates of hygienic behavior. After 24 h the removal of dead brood in native race was significantly higher than that of exotic one being 85.28 and 43.84%, respectively. However, after 48 h the native race significantly removed 97.60% of brood, while ...

Safari parks, roadside menageries, exotic animal auctions and wildlife rehabilitation centres exist world-wide, and serve as sites of wild animal concentrations. When these animals are brought together, the potential is great for the spread and eventual outbreak of many different infectious and parasitic diseases. It is therefore necessary that procedures be developed in these facilities to min...

An increasing number of exotic animals are causing ecological problems. Therefore, for better ecosystem management, it is important to understand how exotic species colonize and adapt to novel environments. The threespine sticklebacks (Gasterosteus aculeatus) can be a good vertebrate model system to explore the ecological and genetic mechanisms of adaptation not only in natural populations, but...

In both the past and the present, the public’s perception of events is certainly shaped by the information transmitted to them through the popular media. Consider the example of the use of exotic animals over the ages. Today, many of us marvel at the sight of wild African and Asian beasts in zoos, circuses and other entertainment venues—an excitement paralleled in Roman antiquity in the arena g...

Skin diseases are common in exotic companion mammal medicine. Some of the diseases are infectious, with potential transmission towards the owners, while others have a metabolic etiology. A list of commonly found dermatologic conditions in exotic companion mammals can be found in Table 1. The approach to skin diseases in exotic companion mammals is similar to that of skin diseases in other compa...
