资源简介:
Non-aquatic reproduction has evolved repeatedly, but the factors that
select for laying eggs on land are not well understood. The treefrog
Dendropsophus ebraccatus has plasticity in reproductive mode, laying eggs
that successfully develop in or out of water. This permits the first
experimental comparison of the selective agents that shape adult
oviposition behavior and embryo developmental capacity. I quantified the
sources and strength of arboreal and aquatic egg mortality, how mortality
varies with weather patterns, and assessed 39 years of daily rainfall
patterns to infer historic levels of egg mortality and effects of climate
change on the selective balance between aquatic and non-aquatic egg
deposition. Aquatic predators and desiccation were the strongest selective
agents in water and air, respectively. Egg mortality varied with weather
such that aquatic oviposition was advantageous when rainfall was low, but
laying eggs out of water increased survival when rainfall was high.
Additionally, I found that since 1972 there have been significant changes
in the patterns of rainfall in central Panama, which has altered the
selective landscape acting on egg-laying behavior. This work provides
insight into both the evolution and maintenance of adaptive phenotypic
plasticity as well as historic and current selection on reproduction.
