Fighting dynamics of male copperheads,Agkistrodon contortrix (Serpentes, Viperidae): Stress-induced inhibition of sexual behavior in losers

Abstract 10.1002/(SICI)1098-2361(1996)15:33.3.CO;2-E Adult male copperheads (Agkistrodon contortrix) fight for priority of access to females during the mating periods in spring and late summer. During fights, one male abruptly quits and retreats, and the other chases in pursuit. One male thus emerges as the winner and the other as the loser. Reversal of this outcome does […]

Using rattlesnake microsatellites to determine paternity in captive bushmasters (Lachesis muta)

We used 10 microsatellite DNA markers originally described for two Crotalus and one Sistrurus species to infer paternity in a captive-hatched clutch of Lachesis muta. Although the dam was known, records listed two potential sires, which prevented the inclusion of those offspring in a captive breeding program. Samples were collected from both possible sires, the […]
