The paradoxical frog Pseudis paradoxa: larval habitat, growth and metamorphosis

, 2009
The genus Pseudis is unique amongst anuran amphibians in that body growth occurs mostly or entirely in the larval phase, with huge tadpoles metamorphosing into adult-sized frogs.

Roles of NET Peptides With Known Antimicrobial Activity and Toxicity in Immune Response. [PDF]

J Immunol Res
Antimicrobial peptides (AMPs) are crucial components of the innate immune system in all living organisms, playing a vital role in the body’s defense against diseases and infections. The immune system’s primary functions include preventing disease‐causing agents from entering the body and eliminating them without causing harm.

Two new records of Pseudis tocantins Caramaschi and Cruz 1998 (Anura, pseudidae) in central Brazil [PDF]

Phyllomedusa: Journal of Herpetology, 2003
Pseudis tocantins was described by Caramaschi and Cruz (1998) based in individuals from the municipality of Porto Nacional, state of Tocantins, collected in 1947. At present, this species is known only from its type locality (Caramaschi and Cruz 1998, Frost 2002). Along the years 1999 and 2001, P.

American bullfrog (Lithobates catesbeianus) distribution, impact on native amphibians and management priorities in San Carlos, Uruguay

Knowledge and Management of Aquatic Ecosystems, 2023
Biological invasions are a major cause of biodiversity and ecosystem services loss. However, information on distribution and impacts is limited for many alien species, restricting the development of local management measures. The aim of this study is: to

Development of blood pressure and cardiac reflexes in the frog Pseudis paradoxsus [PDF]

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1992
Systemic arterial blood pressure and heart rate (fH) were measured in unanesthetized, unrestrained larvae and adults of the paradoxical frog, Pseudis paradoxus from Sao Paulo State in Brazil. Four developmental groups were used, representing the complete transition from aquatic larvae to primarily air-breathing adults.

The role of phytophysiognomies and seasonality on the structure of ground-dwelling anuran (Amphibia) in the Pampa biome, southern Brazil

Anais da Academia Brasileira de Ciências, 2013
Considering that habitat use by amphibians is related both with climate and environmental features, we tested the hypothesis that anuran assemblages found in different phytophysiognomies and in different seasons vary in structure.

Histological skeletochronology indicates developmental plasticity in the early Permian stem lissamphibian Doleserpeton annectens

Ecology and Evolution, Volume 10, Issue 4, Page 2153-2169, February 2020., 2020
This manuscript presents a skeletochronological examination of growth patterns of the early Permian stem lissamphibian Doleserpeton annectens. Through the largest sample size for any Paleozoic tetrapod (n = 60), we identify patterns of developmental plasticity in response to climatic harshness and seasonality that mirror the patterns seen in crown ...
