Soil and surface-dwelling invertebrate samples collected at points sampling marked with "X". 2.1.2.4 Necropsy Necropsies were conducted to 1) identify gender, 2) determine pregnancy status of females, 3) measure testes of males to determine sexual maturity, and 4) document any grossly vis'ible pathological changes. The most numerous mammals captured on the sampling sites were from the genus Peromyscus, probably deer mice (P. maniculatus) and pinon mice (P. truei). The two Peromyscus species were very difficult to positively identify, especially when wet, so all will be identified only as Peromyscus in the remainder of this assessment. Morphological measurements (crown rump length, tail length, hind foot a were made whole using digital micrometer, length) body weight to the nearest 0.1 gm was recorded on an electronic digital balance, and the animal was opened along the ventral midline. Testes length and width were m.easured. The uterus of adult females was opened to look for fetuses and embryo scars indicative of previous pregnancies. - Approximately individuals of 12 animals from each minor species) were sampling site (at least six Peromyscus plus all The prepared for whole body CoC analysis. gastrOintestinal tract was removed from all carcasses to determine CoC concentrations in mammal tissues only. 34 Variable amounts of a variety of food types in the gastrointestinal ecological planning and toxicology, inc. |
