Hematology and Serum Chemistry of Free-Ranging Jaguars (Panthera onca) from a Floodplain Forest Site in Amazonia, Brazil.

We provide hematologic and biochemical information for 13 jaguars (Panthera onca) from the Amazon. Most showed increased lymphocytes, monocytes, eosinophils, aspartate aminotransferase, and alanine aminotransferase; all individuals showed lower mean red blood cell (RBC) counts compared to findings from other biomes. Males had a significantly higher RBC count and alkaline phosphatase than did females.

Spatial patterns of medium and large size mammal assemblages in várzea and terra firme forests, Central Amazonia, Brazil.

Várzea forests account for 17% of the Amazon basin and endure an annual inundation that can reach 14 m deep during 6-8 months. This flood pulse in combination with topography directly influences the várzea vegetation cover. Assemblages of several taxa differ significantly between unflooded terra firme and flooded várzea forests, but little is known about the distribution of medium and large sized terrestrial mammals in várzea habitats.
