Amphibians, with their unique reliance on skin for respiration and ion regulation, are severely threatened by climate change. Rollins-Smith & Le Sage (2023) compiled research on heat-stress and desiccation to better understand future risks. amphibiaweb.org/

IVF for frogs? 💉🧫 🐸 Researchers are looking into repopulating declining species using embryos from frozen sperm and eggs. However, Poo et al. 2022 found IVF frogs smaller than their wild counterparts indicating more research is needed in this area! amphibiaweb.org/

Communication is key when raising kids right? 👨‍👨‍👦! 🐸? Many poison dart frogs have bi-parental care, including multiple types of acoustic communication. Moss, Tumulty, and Fischer (2023) analyzed the evolution of calls dad makes to tell mom to feed baby! amphibiaweb.org/index.html

Many amphibians can adjust hatching times in response to external factors. For terrestrial eggs, flooding can cause embryos to hatch early. Poo et al studied this plasticity in rhacophorid tree frogs in Thailand. amphibiaweb.org/

Brilliantly colored Peruvian Mimic Poison Frog have extensive biparental care. Tadpoles feed on unfertilized eggs rather than the usual tadpole diet of detritus. Weinfurther et al. (2023) found evidence of unique gut microbiome in the egg feeding tads. amphibiaweb.org/

Frog cologne and perfume? 🐸 Chemical signals are likely used during mating in some frogs. Brunetti et al. (2023) found that some of the odors were coming from symbiotic microbial communities found on the skin of Burmeister's Treefrog. amphibiaweb.org/

Rhacophorid tree frogs make up 6% of all anurans. They inhabit a wide range of climates and have evolved multiple modes of reproduction. Ellepola et al (2022) looked into how and why these frogs are so evolutionarily successful. amphibiaweb.org/

👅 🐸 Tadpoles and adult frogs have vastly different diets - herbivorous to carnivorous. Do their tastes change? Possibly! Hao et al 2023 found bullfrog adults and larvae express different genes in their taste receptors. amphibiaweb.org/

Looking to move? Amphibians are generally small and dry out easily, but they often move more than expected. Davis et al 2023 used extensive modeling and 6 years of mark recapture data to understand how and when salamanders move between ponds. amphibiaweb.org/

Did you know? Over 7% of global frog species, are found in 0.7% of the world's land area - on the island of New Guinea. Oliver et al. (2022) documented over 500 species and suggested there may be over 200 more to be scientifically described. amphibiaweb.org/

Brazil is a hotspot for amphibian diversity and decline. Some species are recovering but very slowly. Using past research and museum collections Toledo et al. (2023) documented the recent decline and recovery across species. amphibiaweb.org/
