Discovery of the first wild population of the small red brocket deer Mazama bororo (Artiodactyla: Cervidae).

Mazama bororo was described from a few captive specimens in Brazil by cytogenetic and morphological characters. These specimens supposedly originated in the Southern Atlantic Forest; however, no wild population has been reported. This study was initiated in 1998 to investigate the presence of this species in forest remnants of the Paranapiacaba mountain range, south São Paulo State, Brazil. Five specimens were captured between 2000 and 2002. Cytogenetic analysis from blood samples confirmed its specific identification, documenting the first population of small red brocket deer at the Intervales State Park.

Composition of the first coordination sphere of Ni2+ in concentrated aqueous NiBr2 solutions by x-ray diffraction

Two concentrated solutions of NiBr2 have been examined by x-ray diffraction. The Fourier transformed scattering data indicate inner complex formation between Ni2 + and Br- ions. Average numbers of bonded bromide ions per nickel atom have been determined for each solution and the reliability of the complexation numbers as well as of the other structural parameters has been critically examined. © 1985 American Institute of Physics.

Taxonomic importance of the prefemoral process of the first pair of legs in males of the genus Pseudonannolene (Diplopoda, Spirostreptida)

The first pair of legs in males of some groups of diplopods is modified, having a large coxa and oral projecting prefemoral process; in the family Spirostreptidae (Spirostreptida) this structure has relevance on the genus level. This paper discusses the shape, presence, and absence of the prefemoral process in the genus Pseudonannolene (Pseudonannolenidae, Spirostreptida) and suggests that this structure is an important taxonomic character in this genus and can be used for distinguishing some species.
