Amphibians are currently experiencing the most severe declines in biodiversity of any vertebrate, and their requirements for successful reproduction are poorly understood. Here, we show that supplementing the diet of prey items (fruit flies) with carotenoids has strong positive effects on the reproduction of captive strawberry poison frogs (Oophaga pumilio), substantially increasing the number of metamorphs produced by pairs. This improved reproduction most likely arose via increases in the… 

Figures and Tables from this paper

Testing the effect of dietary carotenoids on larval survival, growth and development in the critically endangered southern corroboree frog.
TLDR
There is no evidence that carotenoid supplementation during the larval life stage improves the growth and development of southern corroboree frogs, and studies are now required for a diversity of anuran species to determine the effects ofcarotenoids on amphibian survival, growth andDevelopment.
Carotenoids and amphibians: effects on life history and susceptibility to the infectious pathogen, Batrachochytrium dendrobatidis
TLDR
It is found that carotenoids can cause lower survival, slower development and growth in amphibians, and no mitigating effects against a common amphibian disease.
The effects of two calcium supplementation regimens on growth and health traits of juvenile mountain chicken frogs (Leptodactylus fallax)
TLDR
It was showed that supplementation treatment did not affect growth or health status as measured through blood analysis, radiography and ultrasonography, and the intermediate diet resulted in previously lower supplementation frogs approximating the higher supplementation frogs in morphometrics and calcium stores.
Nutrition and health in amphibian husbandry.
TLDR
This review identifies several areas where there is substantial room for improvement in maintaining healthy ex situ amphibian populations specifically in the areas of obtaining and utilizing natural history data for both amphibians and their dietary items, achieving more appropriate environmental parameters, understanding stress and hormone production, and promoting better physical and population health.
Meeting ultraviolet B radiation requirements of amphibians in captivity: a case study with mountain chicken frogs (Leptodactylus fallax) and general recommendations for pre-release health screening.
TLDR
It is demonstrated here that, through the appropriate provision of a combination of both UV-B radiation and dietary supplementation, L. fallax can be bred and reared in captivity with healthy skeletal development.
Carotenoid distribution in wild Japanese tree frogs (Hyla japonica) exposed to ionizing radiation in Fukushima
TLDR
It is suggested that carotenoid distribution in amphibians might be less sensitive to ionizing radiation exposure than in other organisms or that the potential deleterious effects of radiation exposure may be less significant or more difficult to detect in Fukushima than in Chernobyl due to, among other things, differences in the abundance and mixture of each radionuclide.
Amphibians and conservation breeding programmes: do all threatened amphibians belong on the ark?
TLDR
It is recommended that species that have been assessed as high priorities for ex situ conservation action are subsequently individually reassessed to determine their suitability for inclusion in conservation breeding programmes.
Development of in-country live food production for amphibian conservation: the mountain chicken frog (Leptodactylus fallax) on Dominica, West Indies
TLDR
The establishment of live food cultures for the Critically Endangered mountain chicken frog (Leptodactylus fallax) at a conservation breeding facility on the Caribbean island of Dominica is described.
A captive breeding experiment reveals no evidence of reproductive isolation among lineages of a polytypic poison frog
TLDR
A captive breeding experiment was used to assess the extent of reproductive isolation among three allopatric, genetically distinct O. pumilio lineages that differ in coloration, and found no evidence suggesting behavioural pre-zyGotic or post-zygotic reproductive isolation, indicating that isolation would not be maintained by intrinsic mechanisms in the event of secondary contact.

A brighter future for frogs? The influence of carotenoids on the health, development and reproductive success of the red‐eye tree frog
TLDR
It is shown that carotenoids influence the development, phenotype and reproductive success of A. callidryas, and these important nutrients should therefore be considered when nutritional recommendations for amphibians are made.
Differences in carotenoid accumulation among three feeder-cricket species: implications for carotenoid delivery to captive insectivores.
TLDR
Overall, this study shows that, by providing captive insectivores with G. bimaculatus crickets recently fed a carotenoid-rich diet, the quantity ofcarotenoids in the diet can be increased.
Carotenoid diet and nestling provisioning in urban and rural great tits Parus major
TLDR
The carotenoid availability in the main diet of breeding great tits Parus major, living in urban and rural environments with known differences in carOTenoid pigmentation, seems to be similar for nestlings in the two environments.
Captive‐breeding programme for the Kihansi spray toad Nectophrynoides asperginis at the Wildlife Conservation Society, Bronx, New York
TLDR
The efforts of the Wildlife Conservation Society (WCS) and the National Amphibian Conservation Center (NACC) to breed these toads in captivity as an integral part of the Kihansi Gorge conservation plan are discussed.
Maternally derived carotenoid pigments affect offspring survival, sex ratio, and sexual attractiveness in a colorful songbird
TLDR
It is shown that the colorful carotenoid pigments that female zebra finches deposit into egg yolks influence embryonic and nestling survival, the sex ratio of fledged offspring, and the eventual ornamental coloration displayed by their offspring as adults.
A Comparison of Oral and Topical Vitamin A Supplementation in African Foam-Nesting Frogs (Chiromantis xerampelina)
TLDR
It is suggested that oral supplementation using a product high in vitamin A may be ineffective at raising whole-body vitamin A levels above those achieved with standard nutrition.
A survey of serum and dietary carotenoids in captive wild animals.
TLDR
Wild captive species demonstrated a wide variety of carotenoid accumulation patterns, which could be exploited to answer remaining questions concerning carotanoid metabolism and function.
Trophic egg laying : hypotheses and tests
TLDR
This paper stresses the importance of elucidating the adaptive function of trophic eggs through explicit hypothesis testing, and outlines key experiments that can test adaptive and functional hypotheses.

TLDR
Nutrient content varied widely between the four insect species and the number of nutrients deficient vs. the NRC requirements for rats on an energy basis by insect species was as follows: soldier fly larvae, tebo worms, Turkestan cockroach nymphs, and adult house flies.
