Frog measurements
Description
Measurements of frogs from several different species with the Zakerana genus.
Usage
frogs
Format
A data frame with 64 observations of 16 variables. Descriptions of variables are from the authors.
- hl
head length distance from tip of snout to the back of mandible
- hw
head width maximum width of the head at the posterior margin of mandible
- mn
distance from back of mandible to nostril
- sl
snout length distance from anterior corner of eye to the tip of snout
- mfe
distance from back of mandible to front of the eye
- mbe
distance from back of mandible to back of the eye
- in
internarial distance
- iod
interorbital distance
- en
distance from front of eyes to the nostril
- ns
nostril—snout length
- el
eye width
- uew
maximum width of upper eyelid
- hal
hand length distance from proximal end of outer palmar metacarpal tubercle to tip of third finger
- fal
forearm length distance from corner of elbow to proximal end of outer palmar metacarpal tubercle
- thighl
thigh length distance from vent to knee
- tl
tibia length distance from knee to heel
- tfol
length of tarsus and foot distance from heel to tip of fourth finger
- fol
foot length distance from proximal end of inner metatarsal tubercle to tip of fourth finger
Details
From the authors: "We describe a new species of frog of the genus Zakerana discovered from the urban core of Dhaka, Bangladesh, one of the most densely populated cities in the world. Although the new species is morphologically similar to the geographically proximate congeners in the Bangladeshi cricket frog group, we show that it can be distinguished from all congeners on the basis of morphological characters, advertisement calls and variation in two mitochondrial DNA genes (12S rRNA and 16S rRNA)."
