Pristimantis

Describimos una nueva especie de Pristimantis conocida del bosque nublado de las estribaciones orientales de los Andes centrales de Ecuador, pristimantis. We describe a new species of Pristimantis, known pristimantis cloud forests of the eastern slopes of central Ecuadorian Andes. The new species is characterized by having distinctive white spots on black venter, pristimantis, green dorsum, conical tubercles on eyelid, interorbital tubercle, and row of ulnar and tarsal tubercles. Efforts to conserve pristimantis species are focused on two protected areas within the Llanganates-Sangay corridor, a hotspot that protects endemic and unknown populations of frogs.

The new species differs from other species of the ridens series by its distinctive dorsal spots, absence of tympanic membrane, presence of enlarged conical tubercles on the eyelid, prominent inter-orbital tubercle, and silver iris with black reticulations.

New species are described every year, mainly from the Andes Lehr et al. The remarkable diversity of this terrestrial group may be associated with the success of their reproductive mode. Our knowledge of the diversity of this genus is thus still incomplete, and the rate of species discovery remains high throughout the Andes, including in eastern Peru, where several species have recently been described e. Here we describe a new species of Pristimantis found in the bromeliads of a cloud forest remnant in the Cordillera de Carabaya Fig. This specimen does not resemble any of the previously described species of Pristimantis. Furthermore, molecular data indicate that the sequence of a fragment of 16S rRNA does not match any known sequence of Pristimantis.

In males, investment is usually related to territorial defense, agonistic, and advertising behavior, whereas females invest more in body growth Heinicke, M. SSD varies in terms of its direction due to differences in the body size of different taxa of vertebrate and invertebrates, with SSD patterns tending to lean towards increased body size in males e. We found that the models that best explained body size in males, females, and SSD contained environmental variations in temperature, precipitation, and elevation as predictors.

According to the team, the new species — named Pristimantis mutabilis mutable rainfrog — changes skin texture in minutes, appearing to mimic the texture it sits on. Skin texture variation in one individual Pristimantis mutabilis ; note how skin texture shifts from highly tubercular to almost smooth; also note the relative size of the tubercles on the eyelid, lower lip, dorsum and limbs.

This deviation of SSD towards females could be related to fecundity selection, which describes the fitness advantages that result from the selection of traits that increase the number of offspring per reproductive period 48 , 49 , Este punto caliente de diversidad al encontrase aislado de la cordillera de los Andes Fig. Additionally, we included altitudinal information to estimate the available habitat formed by the interaction between the topography and macroclimate 41 , Automatic detection of key innovations, rate shifts, and diversity-dependence on phylogenetic trees.
