Amphibian Breeding Strategies
A researcher is suggesting that alternative breeding strategies by amphibians are an attempt to avoid parasites, etc. From the Eurekalert:
"Brian Todd, a researcher at the UGA Odum School of Ecology Savannah River Ecology Lab, explains that most amphibians start their lives in water (tadpoles are a good example), and then make their way onto land as adults and return to the water to breed. But there are other breeding strategies as well. Take, for instance, the Darwin’s frog, the species that swallows its eggs and, a few weeks later, regurgitates its young. Or the marsupial frog, a species that carries its eggs on its back until they hatch. Several species lay eggs in small puddles on land or high up in trees where they hatch as miniature versions of adults, bypassing the larval stage entirely.
"Researchers have hypothesized that natural selection favored these non-traditional breeding strategies as a way to avoid predatory fish or the risk of a breeding pond or stream drying up. In a review article published in the November issue of The American Naturalist, Todd argues that the diversity of reproductive strategies that amphibians employ might also be influenced by the benefits that come from avoiding viruses, fungi and other parasites."

Tenarife Facility
The giant lizard breeding facility in Valle Gran Rey, La Gomera, Tenarife, is using natural methods for hatching eggs of the endangered species. Last year, incubator methods produced far more males than females, so they are hoping this produces a more number of both genders. (News source.)
