In captive and free-ranging populations of bears (family:
ursidae): pp 1-205.
We're talking mostly about cats, canines, and bears: families Felidae, Canidae, and
Ursidae. All vary greatly in size.
Bears (
Ursidae) are less well researched taphonomically but are knmvn scavengers and thc:refore are potential dispersers (Carson et al.
1963: Delayed implantation in the
Ursidae, with particular reference to the black bear.
A fund that has done relatively well--that is, limiting losses--during the bear markets of 2000-2002 and 2008-2009 may be a fund that could do the same in the bear market of 2018 or 2019, or whenever the
Ursidae family comes out of hibernation.
Algunos detalles que llaman la atencion: y es que ciertamente se trata de un 'oso verdadero' (Clase: Mammalia; Orden: Carnivora; Familia:
Ursidae; Subfamilia: Tremarctinae; Genero: Tremarctos Gervais; Especie: Tremarctos ornatus), ello segun su clasificacion taxonomica.

Ursidae) foasiles de Amearica del Sur," Revista del Museo Argentino de Ciencias Naturales, vol.
The skulls have also been used in comparative studies with other bear species, investigating behavioural differences or evolutionary adaptations within the
Ursidae, such as the evolutionary implications of bite mechanics and feeding ecology in bears (Christiansen, 2007).
Our study, among others including work on polar bears (Ursus maritimus; Derocher et al., 2005), indicates that
Ursidae is not among the most sexually dimorphic families of mammals.

Asimismo, la prueba diagnostica empleada en el presente caso no ha sido especificamente validada en hurones criados en cautiverio, aunque ha sido previamente empleada en primates no humanos (Familias Cebidae, Aotidae, Atelidae, Pitheciidae, Homonidae y Cercophiteciidae), carnivoros (Familias Felidae,
Ursidae, Mustelidae y Procyonidae) y artiodactilos (Familia Bovidae) (Munoz et al., 2005; Esteves et al., 2013; Navarro et al, 2015).
