Both of these features complicate the definition and identification of clear call types as a basis for comparison, preventing straightforward extension of the avian and anuran approach to mammals. To date, we are aware of only three studies that have attempted to derive interspecific size-frequency ...

In a revision of basal Dinosauria, Padian and May (1993) discussed the definition of the clade, and redefined it as the latest common ancestor of Triceratops and birds. They also discussed what this definition would do to the most basal taxa, such as Herrerasauridae, and Eoraptor. Padian an...
resulting in fewer individuals hiding during aerial surveys, in accordance with studies in other remote areas36. The effect is especially true for smaller individuals and areas where threats by large carnivore species and humans are common, and groups of elephants tend to be more agitated49. Anothe...
We observed displays to confirm the presence of territorial breeders, and located crags and eyries used for nesting each year. During these visits, we identified territorial individuals based on alphanumeric coloured rings or high-definition pictures that were inspected for individual phenotypic ...
Definition of behavior The scent-markings of urinating on the object with the tail raised above the hip was termed as urine spraying (Fig. 1a) and of bending the hindlimbs to lower the hips and urinating or defecating without raising the tail, and scraping the ground with their hind paws...
of movement after the initial depart from the birthplace can be defined as secondary dispersal22. The operating definition of secondary dispersal is useful because it can be applied to natural populations but also to the case of individuals introduced in a novel environment, regardless of they were...
