Paradoxical frogs are exclusively aquatic anurans distributed across much of South America. They have been the subject of several phylogenetic studies, but the results of these studies are contradictory regarding the monophyly of PseudisWagler, 1830 and the validity of some species, including Pseudis platensisGallardo, 1961.

AbstractPlants and microorganisms establish beneficial associations that can improve their development and growth. Recently, it has been demonstrated that bacteria isolated from the skin of amphibians can contribute to plant growth and defense. However, the molecular mechanisms involved in the beneficial effect for the host are still unclear. In this work, we explored whether bacteria isolated from three tropical frogs species can contribute to plant growth.

AbstractPlants and ants engage in diverse mutualistic interactions that contribute to their adaptive fitness. However, the presence of ants in flowers can generate conflicts between plants and pollinators. These interactions are little studied in temperate grasslands, despite the ubiquitous interactions between ants and plants in this region. In this study, we investigated how the presence and mobility of Camponotus termitarius (Emery) ants on Eryngium chamissonis Urb.

Human populations differ genetically according to their geographic continent of origin (Mallick et al. 2016; Bergström et al. 2020). This diversity also encompasses cultural and linguistic aspects, resulting from the expansion and diversification of these different populations throughout the great human expansion (Henn et al. 2012), which began in Africa ∼300,000 yr ago.
