In addition, it is an explosive breeder throughout North America, South America and West that enters in reproductive activity after the first Indies (Frost, 2020). Popularly known as Butter heavy rains of the season (Maffei et al., 2011). P.

The 11 conversion of natural habitats into human-modified landscapes poses novel and multifaceted 12 environmental stressors to organisms, influencing their ecology, physiology, life history and 13 fitness. Although the effects of LULCC have been studied extensively at the community level, 14 there is scant information about its effect on population and individual characteristics. We 15 assessed the diet composition, body condition, and sexual size dimorphism of the common 16 African toad (Amietophrynus regularis) in urban and agricultural landscape. Diet composition 17 was evaluated using gut content analysis, while body condition was measured using residual 18 mass index. Overall, 935 prey items comprising six classes, at least 18 orders and 31 families 19 were obtained from toads. This broad dietary niche suggested that Amietophrynus regularis is a 20 generalist predator.

DRAGO & LÍA I. LUNASCHI Abstract: Cosmocercoides latrans n. sp. (Cosmocercidae) from the small intestine of 92 (2) Leptodactylus latrans (Anura: Leptodactylidae) from Northeastern Province of Buenos 92(2) Aires, Argentina is described. The new species can be distinguished from their congeners by a combination of the characters, among which stands out the number of rosette papillae, the lack of gubernaculum and the presence of lateral alae in both sexes. There are over 20 species in the genus Cosmocercoides, and Cosmocercoides latrans n. sp. represents the third species from the Neotropical realm and the second for Argentina. Additionally, seven previously known taxa are reported; Pseudoacanthocephalus cf. lutzi, Catadiscus uruguayensis, Rauschiella palmipedis, Aplectana hylambatis, Cosmocerca parva, Schrankiana sp. and Rhabdias elegans; providing literature records and information on distribution and host-parasite relationships. Key words: helminths, Leptodactylus latrans, Cosmocercoides latrans n. sp., anura, Argentina.
