“…Leaf litter anurans are widely known to eat mainly arthropods (Toft 1981, Van Sluys et al 2001, Marra et al 2004, Dietl et al 2009, Martins et al 2010, Almeida-Santos et al 2011, Sugai et al 2012. For example, Zachaenus parvulus (Cycloramphidae) ate mainly Formicidae and Isopoda (Van Sluys et al 2001), Ischnocnema henselii (Brachycephalidae) fed mostly on Araneae and Orthoptera (Dietl et al 2009) whereas Ischnocnema parva consumed predominantly ants and isopods (Martins et al 2010) and Brachycephalus didactylus (Brachycephalidae) ate mainly Collembola and Acari (Almeida-Santos et al 2011).…”

Haddadus binotatus is an endemic anuran of the Brazilian Atlantic Forest and currently, there is no information about the diet of this species. We analyzed the diet of two populations of this anuran in two states in southeast Brazil. Samplings were carried out in 2004 in the state of Rio de Janeiro and in 2009 and 2010 in the state of Espírito Santo. Haddadus binotatus presented a rich diet composition, preying 19 prey types. Orthoptera, Coleoptera, and Blattodea were the most important preys in the Rio de Janeiro population, and Orthoptera, Araneae and Hemiptera were the most important in the Espírito Santo population. The diet composition differed numerically between the two localities, but not in terms of volume, which can reflect local differences in the prey availability in the two habitats. The jaw width limited the size of prey, which is expected for predators who swallow the preys without chewing. The proportion of individuals with empty stomachs was higher in the Rio de Janeiro population (39.2%) than in the Espírito Santo population (17.9%), suggesting that the former could be in a lower energy balance. The females of the species were larger than the males, which may result from the production of larger eggs.

Abstract:In this study, we present some information of the regarding throphic niche from the anuran toad Rhinella icterica living in high altitudes above 2000 m a.s.l. from a habitat of the Atlantic Forest Biome -the Altitude Fields in the Itatiaia National Park. We found 150 prey items in toad stomachs, belonging to five prey types, as well as skin remains and some remains of plant material. The index of relative importance indicated that most important prey types were beetles and ants, these last composing 70% of the diet numerically and the trophic niche breadth (B) was 1.81. The relatively low diversity of prey types we recorded in the diet of R. icterica of Itatiaia and numerically dominated by ants suggests some preference for this item. We do not found significant relationship between the toad measurements with the preys' measurements. We concluded that R. icterica toads at the highlands of Itatiaia feeds on arthropods, mainly ants and coleopterans and that the high consumption of preys with relatively small and similar size as ants in the diet prevents an expected relationship among frog body or mouth size and prey volume and size. Resumo: No presente estudo apresentamos informações sobre o nicho trófico de uma espécie de anuro que reside em altitudes elevadas da Mata Atlântica. Descrevemos a dieta do sapo Rhinella icterica em altitudes acima de 2000 m em áreas de Campos de Altitude no Parque Nacional do Itatiaia. Encontramos 150 itens nos estômagos analisados de R. icterica, divididos em apenas cinco categorias de presa, além de vestígios da própria pele do anuro e restos vegetais. O índice de importância relativa indicou que besouros e formigas foram os itens mais importantes sendo que formigas representam 70% dos itens ingeridos. A amplitude de nicho trófico (B) foi de 1,81. O reduzido número de categorias alimentares, bem como o elevado número de formigas na dieta sugere que R. icterica apresente uma preferência por este item. Não encontramos nenhuma relação significativa entre as dimensões do anuro com as dimensões das presas. Concluímos que a população de R. icterica que habita os campos de altitude de Itatiaia alimentam-se de artrópodes, principalmente formigas e besouros. O alto consumo de presas com tamanho relativamente semelhante e pequeno como, por exemplo, formigas, impede uma relação esperada entre o tamanho do corpo do anuro ou o tamanho de sua mandíbula e tamanho e volume de presas.

“…Anurans ingest prey with size proportional to their JW, thus consuming larger prey as their jaw size increases (e.g. Lima and Moreira 1993, Marra et al 2004, Dietl et al 2009, Martins et al 2010. Smaller preys should be less energetically profitable for adults, and the consumption of larger prey should result in a greater amount of energy.…”

“…This may be due to prey availability, which can be different among areas, differences in periods of collection, altitudes, and/or phylogeny (Sabagh et al 2012). Anurans can also use different types of microhabitat, such as leaf-litter on the forest fl oor, rocks, streams, ponds, lakes, trees, and bromeliads (Eterovick 1999, Almeida-Gomes et al 2008, Duré et al 2009, Martins et al 2010, Ferreira et al 2012. Bromeligenous frogs reproduce, forage and complete their entire life cycle inside bromeliads (sensu Peixoto 1995).…”

In this study, we analyzed diet, sexual dimorphism and bromeliad use in three populations of the hylid frog Phyllodytes luteolus from restinga habitats along the Brazilian coast. We found 13 arthropods categories in 161 stomachs. Ants and termites were the dominant prey items. The similar trophic niche across populations suggests this species has a conservative diet. We found sexual dimorphism regarding body size and jaw width. We recorded P. luteolus in fi ve bromeliad species, but predominantly in Aechmea blanchetiana (35.6% of individuals recorded). We recorded solitary individuals in 44% of occupied bromeliads, and never found two males sharing the same bromeliad. The data is suggestive that populations of P. luteolus has a conservative diet independent of area, with ants and termites the being most relevant prey items. The sexual dimorphism in jaw and the solitary males may suggest that this species have territorial behavior.
