Event 20: Breeding Decisions of your Lance Tailed Manakin of Panama which have Emily DuVal
Our very own guest inside event is Dr. Emily Duval whoever Duval lab during the Florida Condition School knowledge behavioural environment, population genes, as well as in the latest character from intimate solutions in the speciation.
Several mating, where you to definitely women bird copulates along with that male was popular from the bird, and creature kingdom. Which ain’t simple, especially in socially monogamous variety (these are generally wild birds) performing below biparental worry– each other Dad and mom keep up with the egg. Hence, lady wild birds must be selective. They want to improve the opportunity that the egg commonly change in order to young ones. Just how do they do this? Of the mating with high-top quality “alpha” guys that have a good genetic info.
In the lekking variety, men screen for ladies, however, do-little else once they features mated. What about cooperation in the place of battle anywhere between a couple males?
