Antioxidants defend barn swallow sperm from radiation

Exposure to free radicals can affect sperm morphology and behaviorin a setting such as Chernobyl, these effects could help determine the fate of an entire species' existence. For example, studies of barn swallows, Hirundo rustica, from radioactively contaminated areas around Chernobyl have shown changes in sperm motility and the frequency of abnormal sperm related to radiation levels. Naturally, mutations that prevent sperm from effectively swimming could lead to population declines.

Andrea Bonisoli Alquati from the University of South Carolina and colleagues analyzed the effects of radiation, namely oxidative damage, in barn swallow populations inhabiting areas near Chernobyl. As the researchers will discuss at ESA's Annual Meeting, the findings suggest "a possible radioprotective role for antioxidants in free-ranging animals exposed to the fallout from Chernobyl."

The contributed oral session "Antioxidant defenses and sperm swimming behavior in barn swallows from Chernobyl," led by Andrea Bonisoli Alquati, University of South Carolina, will be held Monday, August 2, 2010 at 2:10 pm.

Other sessions on mate selection and reproduction include:

The poster session "Staying in the red: mating preferences for novel coloration in zebrafish (Danio rerio)" by M. Aaron Owen, Purdue University; the contributed oral session "Balancing the demands of migration and the physiological transition to breeding in Neotropical songbirds: a dual role for testosterone?" led by Christopher M. Tonra, Universi
