These fungi comprised a variety of potential and opportunistic species
of fungi which were also in accordance with previous literature3 (Table-2).
Androctonus australis, opportunistic species
, omnipresent in all biotopes, is the only species that lives close to man.
aurita is a generalistic, and opportunistic species
, seasonal variations in resource availability seem to affect its diet (Lessa & Geise 2010).
This is the second most common fungal disease in immunocompromised patients, but some opportunistic species
infect immunocompetent hosts.
In these cases, the opportunistic species
would be favored by the increase of food availability, as a result of discarded organisms (Britton & Morton, 1994; Morton, 1995, 2006; Escolar et al.
Epidemiology: Lernaea cyprinacea is an opportunistic species
which infecting the fishes of many families and widely distributed in Eurasia, North America and Southern Africa mainly via translocation of edible ornamental cyprinids .
Ever since it was built some 145 years ago, the Suez Canal has acted as a corridor for the invasion of foreign species into the Mediterranean, Galil explained: As aggressive, opportunistic species
arrive in the Mediterranean, they quickly spread without natural enemies such as parasites or predators to check them.
quelen behaves as an opportunistic species
that exploits the resources available at the environment and the intensity of consumption of food items of allochthonous and autochthonous origin may depend on the order of lotic systems and the kind of interaction between the marginal vegetation and the water system, and it consists mainly by allochthonous items to the diet of fishes in environments of lower order and autochthonous items in those living in larger environments.
The succession of species starts with the decay of any organic matter that has built up during the dry phase, breaking down to provide food for a bacterial bloom, and can finish with opportunistic species
of birds which have the mobility to exploit ephemeral resources.
A statistically significant correlation was found between the proportion of opportunistic species
(calculated based on biomass data) and the concentrations of total nitrogen and Chl a.
But some opportunistic species
such as crows and common myna are increasing in number because they have adjusted themselves according to the changing habitat conditions.
The decline in habitat quality for wildlife due to landscape fragmentation and the colonisation of opportunistic species
has also reduced wildlife populations.
