Welcome to the Jungle: An Examination of the Making of Science Standards
Science Education, Volume 110, Issue 5, Page 1278-1301, September 2026.ABSTRACT Nearly 50 million public school students in the United States are required to learn the content prescribed by state‐mandated science standards. Although much is known about the implementation of science standards and teachers' perceptions of them, the development process of these standards remains unclear.

Redescripción de la morfología larval externa de dos especies del grupo de Leptodactylus fuscus (Anura, Leptodactylidae) [PDF]
Phyllomedusa: Journal of Herpetology, 2005 The larvae of Leptodactylus gracilis (D’Orbigny y Bibron, 1840) and L. mystacinus Bumeister, 1861 are re-described and compared with previous descriptions noting intraspecific variation in oral disccharacteristics (arrangement of papillae and rows of ...

Nature, 1911 AT the beginning of April last I collected some frog ova for the purpose of making observations on development. Tadpoles appeared about April 9, and from time to time from that date until July 17, when young frogs were developed, I took batches away for preservation and sectioning.

Antipredatory Strategies of Anurans: An Updated Conceptual Review
Ethology, Volume 132, Issue 9, Page 662-708, September 2026.To unravel the evolutionary dynamics of predator–prey interactions, we propose an updated, three‐tiered classification of anuran antipredatory strategies. By mapping non‐behavioral, individual, and group defenses across five functional phases, this integrative framework introduces the concept of synergetic coupling.

The Anatomical Record, Volume 309, Issue 8, Page 2151-2175, August 2026.Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.

Effects of Timing of Microbial Exposure on Microbiome Assembly and Amphibian Immune Development
Ecology and Evolution, Volume 16, Issue 8, August 2026.We used a novel amphibian gnotobiotic system to investigate how disruptions to the microbiome during critical developmental periods influence microbial assembly and the development of immunity. We found that antimicrobial treatments of embryos and subsequent introduction to microbes at different developmental stages altered microbiome assembly ...

Journal of Animal Ecology, Volume 95, Issue 8, Page 1358-1371, August 2026.Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Phyllomedusa: Journal of Herpetology, 2023 In aquatic environments, many prey animals, including anuran larvae, predominantly use chemical cues to assess predation risk. In such systems, a variety of chemical cues (e.g., kairomones, alarm, dietary) affect the behavioral responses of the ...
