Historically, the definition of cursorial was based qualitatively on an animal's morphology and behaviour, generally referring to large, terrestrial mammals that ran fast or far across open spaces. However, in recent years, as biomechanicists have learned how to quantify aspects of limb movement ...

The Mann-Kendall trend test, introduced by Gilbert (1987), is employed in this study to determine if any trend is present within the long-term series of NDVI, precipitation and derivatives, and temperature. The NDVI time series was analysed on an annual basis as well as with a focus on t...

The global trade in wildlife affects ~24% of all extant terrestrial vertebrate species on Earth (Scheffers et al., 2019), and is known to be a major driver of species extinctions and animal welfare abuses (e.g. Baker et al., 2013; Challender et al., 2015; Dutton et al., 2013; Fe...
In many contributions dealing with dinosaur ichnology, it is common to find a section where the systematic affinity of the trackmaker is discussed. This approach has been devel- oped since the beginnings of vertebrate paleoichnology (e.g. Beckles, 1862; Hitchcock, 1836) and continues to be ...
true salamander." People typically describe true salamanders as living a highly aquatic existence and newts as more terrestrial animals, although most still have an aquatic life stage. A clear difference between them is that newt's skin is usually rough and wrinkled while salamander's skin is ...
The study of Sarcopterygii provides insights into the evolution of terrestrial locomotion. 5 Actinopterygii Actinopterygii (New Latin actino- ('having rays') + Greek πτέρυξ (ptérux 'wing, fins')), members of which are known as ray-finned fishes, is a clade (traditionally class or...
the Gymnophiona branch (branch 1) that are involved in the ECM-receptor interaction pathway with a binding interaction (blue line) between lamc1 and itga3, and a reaction interaction (black line) between vwf and qsox1 (the latter protein-coding gene is part of a second shell of ...
The primary food source for young mammals is milk from their mothers. 9 Birds Majority are adapted for flight. Penguins are birds that have adapted to swim rather than fly. 1 Mammals Diverse class ranging from aquatic to terrestrial species. Whales and bats are both mammals, but one swims wh...
