Facility design and associated services for the study of amphibians

The role of facilities and associated services for amphibians has recently undergone diversification. Amphibians traditionally used as research models adjust well to captivity and thrive with established husbandry techniques. However, it is now necessary to maintain hundreds of novel amphibian species in captive breeding, conservation research, and biomedical research programs. These diverse species have a […]

Deciphering Amphibian Declines


Ghosts in Our Midst: Coming to Terms with Amphibian Extinctions

A global mass extinction of amphibians is well under way, driven both by habitat loss and by environmental changes. As amphibian communities in Central America are being decimated by chytrid disease, scientists are working to fashion an emergency response. They are also sending out an urgent warning about what the loss of these environmentally sensitive […]

Amphibian Biology and Husbandry

Extant amphibians comprise three lineages– salamanders (Urodela or Caudata), frogs and toads (Anura), and caecilians (Gymnophiona, Apoda, or Caecilia)–which contain more than 6,000 species. Fewer than a dozen species of amphibians are commonly maintained in laboratory colonies, and the husbandry requirements for the vast majority of amphibians are poorly known. For these species, a review […]

Call Patterns and Basilar Papilla Tuning in Cricket Frogs. I. Differences among Populations and between Sexes

Male cricket frogs (Acris crepitans) produce a broad-band, high frequency advertisement call with a single spectral peak (the dominant frequency). We measured the dominant frequencies of male calls from six populations in central Texas and one from Indiana and compared them to the tuning of basilar papilla afferents in males and females. Averaging over all […]

The amphibian auditory system as a model for neurobiology, behavior, and evolution

Ultraviolet light and reptiles, amphibians

Ultraviolet lighting is integral for the growth and maintenance of many reptile and amphibian species. But providing an adequate source of light can be challenging. Many disease processes seen by veterinarians are attributed to ultraviolet lighting deficiencies. In mammals, disease due to excess ultraviolet lighting has been noted, and some veterinarians feel this may be […]

A complex Enrichment Diet improves growth and health in the endangered Wyoming toad (Bufo baxteri)

Abstract 10.1002/zoo.20223.abs The endangered Wyoming toad (Bufo baxteri) suffers nutrition related pathologies including poor growth and feeding difficulties from squamous metaplasia. Juvenile B. baxteri were each fed three supplemented feeder diets over 22 weeks and their growth, strike rate, and ingestion success measured. Diet (1) Enrichment Diet: feeder crickets fed fish oil, spirulina, and ground […]

Non-invasive treatments of luteinizing hormone-releasing hormone for inducing spermiation in American (Bufo americanus) and Gulf Coast (Bufo valliceps) toads

Abstract 10.1002/zoo.1007.abs As many as 20% of all assessed amphibian species are threatened with extinction, and captive breeding programs are becoming important components of conservation strategies for this taxon. For some species, exogenous hormone administration has been integrated into breeding protocols to improve propagation. However, most treatments are administered by an intraperitoneal injection that can […]

Acute stressors increase plasma corticosterone and decrease locomotor activity in a terrestrial salamander (Desmognathus ochrophaeus)

Vertebrates respond to the onset of an acute stressor with an acute increase in plasma glucocorticoids. The increase in plasma glucocorticoids is believed to be adaptive, helping an animal cope until the stressful episode subsides. Although much is known about the effects of chronic elevation of glucocorticoids, far less is known about the role of […]
