Abstract:

Anurans play a crucial role as bio-indicators of environmental changes in
their ecosystem and their parasite populations can act as markers of
environmental health since changes in their population may be related to
changes in the quality of their environment. Therefore, this study was
carried out to explore the anurans’ diversity and their gastrointestinal
helminths parasites within the University of Ibadan campus in order to
ascertain the richness of the in the environment. A total of 225 anurans were
captured using a combination of live capture sampling techniques and
auditory-visual methods from four sampling locations within University of
Ibadan, namely- Awba Dam, Heritage Park, Awba-Stream, and Ona River.
The collected anurans were identified and examined for gastrointestinal
parasites using standard protocols. Five anuran species; Sclerophrys
maculate, S. pusilla, S. regularis, S. steindachneri and Bufo bufo were
encountered and all were infected with parasites. Cephaloclamys
compactus, Aplectana chamaeleonis and Ophidascaris (Trematoda),
Pharyngodon and Kalicephalus (Nematoda) and Acanthocephalus bufonis
(Acanthocephalan) were identified parasites. Ona River had the highest
anuran diversity having all the five encountered amphibians. This study has
provided valuable insight to anurans diversity including prevalence and
intensity of their parasite.
