“…Other studies of parental care have shown that defense against predators is an important function of egg attendance (Melber & Schmidt 1975;Raquena et al 2009;Vockenhuber et al 2009), and our results confirm this function. While we did not observe males physically repelling predators, several instances of such behavior have been reported in other amphibians (Forester 1978;Cook et al 2001;Valencia-Aguilar et al 2012). Interestingly, many predation events we observed occurred during the day, when males are often absent.…”

Impacts of Paternal Care and Seasonal Change on Offspring Survival: A Multiseason Experimental Study of a Caribbean Frog

Parental care is widespread among animals and many studies have investigated how environmental conditions influence parental care strategies. However, few studies have coupled observations of the frequency and form of parental care with manipulative studies on the function of care across multiple seasons. To address this gap, we made field observations and conducted male removal experiments in a glass frog with paternal egg attendance from the island of Tobago, West Indies. To test the hypothesis that seasonality impacts the frequency, form, and function of parental care, field observations and male removal experiments were undertaken three times, twice during the rainy season, and once in the dry season. We found seasonal differences in the frequency of egg attendance with males increasing the frequency of this behavior in the dry season, likely in response to a greater risk of clutch desiccation. We also found that clutches in which the male was removed had strongly reduced survivorship compared with controls and this pattern did not change seasonally. However, sources of mortality were strongly influenced by season. Arthropod predation was the primary source of mortality during the wet season, but in the dry season, desiccation was more important. Together, these results suggest that seasonal variation is both impacting care function as well as shaping the form that parental care takes.

“…Developmental rate can be influenced by egg size and temperature with embryos developing more slowly in cooler temperatures (Duellman and Trueb 1994). Valencia-Aguilar et al (2012) did not report egg size or incubation temperature; because their study sites were at higher elevations (350 m and 210 m) than ours, the temperature may have been cooler. Hawley (2006) reported neither temperature nor egg size and Delia et al (2014) did not report temperature, but their study site was at an altitude of 750 m (Delia, pers.…”

“…In the 30 species of Hyalinobatrachium, egg masses usually are laid on the undersides of leaves, where they apparently are guarded by males (Villa 1984, Vockenhuber et al 2009, Delia et al 2010, Lehtinen and Georgiadis 2012, Murphy et al 2012, Valencia-Aguilar et al 2012, Delia et al 2014. In most other centrolenid genera, eggs are deposited on the upper sides of leaves and there is no evidence of parental care (Hoffmann 2010), except for female care in Ikakogi tayrona (Guayasamin et al 2009).…”

Oviposition and development in the glass frog Hyalinobatrachium orientale (Anura: Centrolenidae). Oviposition and external embryonic developmental features are described in the Tobago glass frog, Hyalinobatrachium orientale. Egg clutches are nearly always laid on the undersides of leaves (one exception); usually leaves of Heliconia sp. are used, but Philodendron and palms may be used in the absence of Heliconia. Clutches contain 28.0 ± 5.3 eggs (mean ± SD) and eggs are 1.86 ± 0.11 mm in diameter. The behavior of one amplectant pair was followed for more than five hours; the pair rotated several times around a small area of the leaf depositing eggs in a tight spiral formation. External embryonic features were observed by scanning electron microscopy. Surface ciliation is extensive up to the time of hatching when it is lost; external gills are short and a cement gland is absent. Hatching gland cells were detectable on the anterodorsal surface of the head from Day 4 after deposition and persisted until at least Day 10, and hatching occurred between Days 9 and 16. During this period, progressive development in tail length, surface pigmentation, intestinal coiling, and oral disc features was observed. Post-hatching larvae reared for six weeks grew 37% in length and tripled in weight, but remained at Gosner Stage 25.Keywords: amphibians, embryonic development, glass frogs, oviposition, Tobago, West Indies.Resumo Ovipostura e desenvolvimento na perereca-de-vidro Hyalinobatrachium orientale (Anura: Centrolenidae). Descrevemos aqui características da ovipostura e do desenvolvimento embrionário externo da perereca-de-vidro de Tobago, Hyalinobatrachium orientale. Os ovos são quase sempre depositados na superfície abaxial das folhas (com uma exceção). Geralmente, são usadas folhas de Heliconia sp., mas, na ausência destas, podem ser usadas folhas de Philodendron sp. e de palmeiras. As desovas contêm 28,0 ± 5,3 ovos (média ± DP) e os ovos possuem diâmetro de 1,86 ± 0,11 mm. O comportamento de um casal em amplexo foi acompanhado por mais de cinco horas; o casal girou 4 Phyllomedusa -14(1), June 2015 diversas vezes em torno de uma pequena área da folha, depositando os ovos em uma formação espiral apertada. As características embrionárias externas foram observadas por microscopia electrônica de varredura. A ciliação é extensa até o momento da eclosão, quando é perdida; as brânquias externas são curtas, e não existe uma glândula de cemento. Células glandulares de eclosão foram detectadas na superfície anterodorsal da cabeça a partir do dia Dia 4 após a ovipostura e persistiram até pelo menos o Dia 10, e a eclosão ocorreu entre os Dias 9 e 16. Durante esse período, foi observado o desenvolvimento progressivo do comprimento da cauda, da pigmentação superficial, do enovelamento do intestino e das características do disco oral. Após a eclosão, larvas criadas por seis semanas cresceram 37% no comprimento e tiveram seu peso triplicado, mas permaneceram no estágio 25 de Gosner.Palavras-chave: anfíbios, desenvolvimento embrionár...
