Tadpole bodies are compressed dorsoventrally. The eyes are widely spaced, pointed laterally, and small. Mouth is ventral and small with surrounding papillae, except on anterior region of upper lip (Canesco-Marquez et al. 2018, Taylor 1940).
A character that distinguishes B. dendroscarta from other Bromeliohyla are their heavily pigmented gums between and at the base of their teeth (Taylor 1940).
In life, B. dendroscarta’s color varies, ranging from yellow with small brown dots on the dorsal surface to green on the dorsal surface of the arms, head, and legs. The iris of the eyes are golden with black reticulations. Ventral surfaces are lemon yellow. In alcohol, the dorsal surface is a faint lavender color, while the ventral surface is a creamy white that looks spotted while under a microscope (Canesco-Marquez et al. 2018, Taylor 1940).
Tadpoles bodies and tails are cream-colored, and the venter is transparent (Canesco-Marquez et al. 2018, Taylor 1940).
Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
Bromeliohyla dendroscarta is arboreal and uses bromeliad plants as a microhabitat for refuge and reproduction. The frog's abundance is usually higher in habitats that contain higher densities of bromeliads (Canesco-Marquez et al. 2018, Vasquez-Cruz et al. 2019).
Primarily, B. dendroscarta utilizes the bromeliads for the protection of its egg clutches and tadpoles (Canesco-Marquez et al. 2018, Vasquez-Cruz et al. 2019).
Since egg clutches can be found in bromeliads with every season, it can be assumed that reproduction happens year-round for B. dendroscarta (Canesco-Marquez et al. 2018, Vasquez-Cruz et al. 2019).
Bromeliohyla dendroscarta tadpoles have been reported to only consume detritus and decaying arthropods that fall into the bromeliads they are housed within, making growth and development highly dependent on the plants and their interactions with arthropods (Canesco-Marquez et al. 2018, Vasquez-Cruz et al. 2019).
Trends and Threats
The species was not seen between 1974 and 2018 (Santos-Barrera and Canseco-Márquez 2004, Canseco-Marquez et al. 2019).
Possible reasons for amphibian decline
General habitat alteration and loss
Based on morphology and life history, B. dendroscarta was thought to be closely related to B. bromeliacia (Duellman 1970). This was further supported by Faivovich et al. (2005) in their phylogenetic analysis of nuclear and mitochondrial genes of the family Hylidae that included both species. Based on this evidence, Faivovich et al. (2005) created the genus Bromeliohyla. In 2018, Faivovich et al. re-estimated the Hylidae phylogeny resulting in the addition of B. melacaena (formerly of the genus Isthmohyla) to the genus Bromeliohyla with 87% jackknife support. However, the 2018 analysis did not include all three members of Bromeliohyla.
The genus name Bromeliohyla is the combination of the words “Bromelia” and “Hyla”, to represent the characteristic behavior of breeding in bromeliads (Faviovich et al. 2005).
