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 ...
