The Center for Ecological Development and Recreation (CEDAR) is an ecotourism site comprised of natural and human-modified ecosystems in Bukidnon, Philippines. With very little existing research on the influence of human-modified ecosystems on amphibian assemblages in the Philippines, we designed this study to evaluate amphibian assemblages in CEDAR. Using a combination of transects sampling, active searching, and auditory samplings, amphibian samplings were conducted at three sites: a human-modified area, a dipterocarp forest, and the Dila River System. A total of 425 individuals of 18 species from 13 genera and 7 families were documented. The family Ceratobatrachidae was the most represented group, with four species. Out of 18 species, 14 (78%) were Philippine endemics, indicating a high rate of amphibian endemism at CEDAR. In terms of IUCN conservation status, 14 out of 18 species were classified as Least Concern and two as Near Threatened, while two have undetermined conservation status. The Shannon-Weiner and Gini-Simpsons Diversity values revealed that the Human-modified area had the highest diversity compared to the Dila River System and dipterocarp forest. Surprisingly, the human-modified area in CEDAR was found to be the habitat of many anuran species, in particular, a number of generalist species, whilst some specialist species were restricted to natural habitats like the dipterocarp forest and Dila River System. The high amphibian diversity in the human-modified area requires further field studies; hence, additional amphibian samplings are recommended. Long-term wildlife evaluation and monitoring should be carried-out in CEDAR to facilitate the conservation of amphibian populations and their natural habitats in this area.

This study was carried out between October 2020 and October 2021 with the aim of determining sustainable management options and nutrition for the domestication of Mormyridae fish species living in the lower reaches of the Sanaga River in central Cameroon. For this purpose, 451 specimens collected from local fishermen were identified and grouped into 4 genera and 7 species (20.84% Campylomormyrus phantasticus (Pellegrin), 5.32% Hippopotamyrus castor Pappenheim, 24.61% Mormyrops anguilloides (Linnaeus), 18.63% Mormyrops caballus (Pellegrin), 4.66% Mormyrops zanclirostris (Günther, 1867), 15.52% Mormyrus rume Valenciennes, and 10.42% Mormyrus tapirus Pappenheim). Fishes were measured, and parameters were obtained after dissection using intestinal morphometric characteristics and stomach content analysis methods. The emptiness coefficient varied from 0% (Hippopotamyrus castor and Mormyrops zanclirostris) to 26.66% (Mormyrus rume). The relative mass of the intestine was low in all studied species; the intestinal coefficient and the Zihler index of all these species are within the range of carnivorous species. Analysis of stomach contents revealed a broad food spectrum containing twelve categories of prey. Insects, macrophytes and larval shelters were the preferred foods of Mormyrops anguilloides, Mormyrops caballus and Mormyrops zanclirostris, while insect larvae and larval shelters were the preferred prey for other species. Site and season had little effect on the categories of prey consumed by these species.

Identification and characterisation of urban habitats and ascertaining their species associations are essential for the conservation and management of biodiversity in urban landscapes. The study attempts to identify, describe and categorise potential urban habitats in Kochi city, Kerala, India, and to explore the association of bird faunal assemblages with each of the habitats. The study was conducted from June 2018 to May 2020. The Urban Habitat Categories were identified, described and categorised as per the Urban Habitats Biodiversity Assessment (UrHBA) procedure and asample biotope map was prepared. The habitat association of bird species was determined from each of the identified Urban habitat Category by evaluating the species composition of each habitat. Species sharing between the identified habitats was also examined. Critical habitats of conservation concern were identified and their specific features were ascertained. A total of 38 Urban Habitat Categories were characterised from the landscape of Kochi City with 162 species of birds to be found associated with the urban habitats. The wide variety of urban habitats provide excellent dwellings for a large number of birds including several threatened and migratory species. Out of the five major urban habitat categories, most of the species utilise Sparsely vegetated - Life form categories. Among the 38 urban habitats, Forest phanerophytes supports greater number of bird species. Vegetation structure is an important factor that determines bird diversity of the urban habitats. Together with the well-vegetated habitats, sparsely vegetated, non-vegetated and artificial built habitats also significantly contribute to biodiversity of urban centres. The diverse urban habitats and the associated bird species identified from Kochi city emphasise that modified urban landscapes are equally potent as natural landscapes in upholding diverse life forms. The study highlights the necessity of maintaining habitat complexity in urban landscapes for sustainable conservation of urban biodiversity. The baseline data on urban habitats and their species association will serve as a planning tool for safeguarding the critical habitats.
