During June 15-18, 1864, the Federal Army of the Potomac launched a series of attacks against the vital Confederate rail center of Petersburg, Virginia.

Secondly, the study looks carefully at the tactical situation on each of the four days of fighting. Thirdly, the paper reveals the personal side of combat through the use of soldiers° diaries, letters, and regimental histories. The thesis conc...

Sexing wild marine mammals that show little to no sexual dimorphism is challenging. For sirenians that are difficult to catch or approach closely, molecular sexing from tissue biopsies offers an alternative method to visual discrimination. This paper reports the results of a field study to validate the use of two sexing methods: (1) visual discrimination of sex vs (2) molecular sexing based on a multiplex PCR assay which amplifies the male-specific SRY gene and differentiates ZFX and ZFY gametologues. Skin samples from 628 dugongs (Dugong dugon) and 100 Florida manatees (Trichechus manatus latirostris) were analysed and assigned as male or female based on molecular sex. These individuals were also assigned a sex based on either direct observation of the genitalia and/or the association of the individual with a calf. Individuals o...
