Landing in basal frogs: evidence of saltational patterns in the evolution of anuran locomotion

  title={Landing in basal frogs: evidence of saltational patterns in the evolution of anuran locomotion},
  author={Richard L Essner and Daniel J. Suffian and Phillip J. Bishop and Stephen M. Reilly},
All frogs are assumed to jump in a similar manner by rapidly extending hindlimbs during the propulsive phase and rotating the limbs forward during flight in order to land forelimbs first. However, studies of jumping behavior are lacking in the most primitive living frogs of the family Leiopelmatidae. These semi-aquatic or terrestrial anurans retain a suite of plesiomorphic morphological features and are unique in using an asynchronous (trot-like) rather than synchronous “frog-kick” swimming… 

Functional evolution of jumping in frogs: Interspecific differences in take‐off and landing

The first comparative description of the entire process of jumping in frogs is provided, including the first description and comparison of kinematics of the hindlimbs, forelimbs and body during take‐off and landing in relation to ground reaction forces in four frog species spanning the frog phylogeny.

Cooperation behavior of fore‐ And hindlimbs during jumping in Rana dybowskii and Xenopus laevis

It is found that the Rana dybowskii's fore‐ and hindlimbs had good cooperation during jumping, while the Xenopus laevis' uncooperative behavior in limbs may give a functional explanation for the deficiency in terrestrial jumping.

The scratch-digging lifestyle of the Permian “microsaur” Batropetes as a model for the exaptative origin of jumping locomotion in frogs

Batropetes may represent an analog or possibly a homolog of the digging stage that preceded the origin of Salientia, and the possibility of homology with the digging lifestyles of other “microsaurs” and other amphibians is discussed.

The evolution of jumping in frogs: Morphological evidence for the basal anuran locomotor condition and the radiation of locomotor systems in crown group anurans

A new pattern for the evolution of pelvic systems and locomotor modes in frogs is presented and it appears that the advent of a bicondylar sacro‐urostylic articulation was originally related to providing axial rigidity to lateral‐bending behaviors rather than sagittal bending.

The scratch-digging lifestyle of the Permian “microsaur” Batropetes Carroll & Gaskill, 1971 as a model for the exaptative origin of jumping locomotion in frogs

Batropetes may represent an analog, or possibly a homolog, of the digging stage that preceded the origin of Salientia Laurenti, 1768, and the possibility of homology with the digging lifestyles of other “microsaurs” and other amphibians is discussed.

Do all frogs swim alike? The effect of ecological specialization on swimming kinematics in frogs

It is concluded that it is important to analyze frog locomotion in a broader ecological and evolutionary context if one is to understand the evolutionary origins of this behavior.

Walk before you jump: new insights on early frog locomotion from the oldest known salientian

It is shown that limb data correlate with locomotion, regardless of phylogenetic relatedness, and indicate that salamander-like lateral undulatory movements were the main mode of locomotion of T. massinoti.

Frog origins: inferences based on ancestral reconstructions of locomotor performance and anatomy

This work provides data on jumping performance (forces and acceleration) in 20 species of extant frogs including representatives of most of the early radiating clades and uses ancestral character value inferences to assess ancestral features.

Patterns of fluctuating asymmetry in the limbs of anurans

The hypothesis that natural selection for increased locomotor performance may influence patterns of FA seen in vertebrate limbs is consistent, with all species displaying lower mean FA in the hindlimbs.



Origins of the frog-kick? Alternate-leg swimming in primitive frogs, families Leiopelmatidae and Ascaphidae

This work examined swimming in the most morphologically archaic living frogs: the genera Leiopelma, endemic to New Zealand, and Ascaphus, from North America, and although these frogs jump when they are on land, they swim using alternating leg movements.

The Evolution of the Functional Role of Trunk Muscles During Locomotion in Adult Amphibians1

Within amphibians the authors see multiple functional and morphological elaborations of the axial musculature that appear to be associated not only with movement into terrestrial habits (salamanders), but also with subsequent locomotor specializations of two of the three major extant amphibian clades (frogs and caecilians).

Two distinct gait types in swimming frogs

It is demonstrated that alternating-leg swimming is used quite frequently and that it results in a significantly lower velocity to the one obtained by using in-phase leg movements, likely to be associated with energetic costs.

Hopping and swimming in the leopard frog, Rana pipiens: I. Step cycles and kinematics

This study presents a model for the step cycle patterns used during both hopping and swimming by the leopard frog, Rana pipiens. The two behaviors are essentially similar in movement pattern and in

An Early Jurassic jumping frog

The discovery of the earliest known frog is reported, associated with caecilians that retained limbs7, that exhibits primitive characters but shares with later anurans such features as fusion of the caudal vertebrae (urostyle), a rod-like ilium, and elongate hind limbs.

Take-off and landing forces in jumping frogs

The landing phase during locomotion in Rana esculenta is studied by measuring the ground reaction forces during propulsion and landing over a range of distances by using a spring-dashpot model to model the effect of arm angle at touch down.

Hindlimb extensor muscle function during jumping and swimming in the toad (Bufo marinus).

It appears that toad hindlimb function is altered between jumping and swimming, and these functional differences are influenced by passive effects associated with physical differences between the external environments, but are also actively mediated by shifts in the motor output and mechanical behavior of several muscles.


An analysis of functional correlation or habit pattern from the Recent to the Triassic (or Carboniferous) and the establishment of a step-by-step sequence may force a rethinking of the meaning of the "functional" steps ordinarily alluded to en passant.

Do toads have a jump on how far they hop? Pre-landing activity timing and intensity in forelimb muscles of hopping Bufo marinus

To the authors' knowledge, these data represent the first demonstration of tuned pre-landing muscle recruitment in anurans and raise questions about how important the visual, vestibular and/or proprioceptive systems are in mediating this response.

Pelvic and thigh musculature in frogs (Anura) and origin of anuran jumping locomotion

Comparative analysis of the anuran pelvic and thigh musculoskeletal system revealed that the thigh extensors, responsible for the initial phase of jump, the propulsive stroke in swimming and, if used
