Read MoreProductive Vernal Pools
Have you ever wondered what might be hiding just beneath the water’s surface in these temporary pools that crop up in early spring? This little clip reveals a productive vernal pool that has a number of spotted salamander (Ambystoma maculatum) egg masses nestled within the leaf litter of the pool floor. These pools are an important breeding area for several amphibian species, as you can see, because they provide a safe fish-less environment for the eggs and eventual tadpoles to...
Read MoreUnderwater World
While these little white puffs may look like little air pockets escaping from underwater volcanoes they are actually little spermatophores, or sperm packets produced by male spotted salamanders (Ambystoma maculatum), scattered across a vernal pool floor. As females arrive and enter ephemeral pools (sometimes up to a week after the males), males go into a frenzy. Typically the ratio of males to females in the pools is very skewed, with many males to every one female. This fuels some pretty intense male to male competition and very interesting sexual selection. Males surround females and nudge...
