Nitric oxide signaling differentially affects habitat choice by two larval morphs of the sea slug Alderia willowi: mechanistic insight into evolutionary transitions in dispersal strategies
Journal of Experimental Biology
In many marine animals, adult habitat is selected by lecithotrophic (non-feeding) larvae with a limited lifespan. In generalist species, larvae may increasingly accept sub-optimal habitat over time as energy stores are depleted (ʻdesperate larva' hypothesis). If the fitness cost of suboptimal habitat is too high, larvae of specialists may prolong the searching phase until they encounter a high-quality patch or die (ʻdeath before dishonor' hypothesis). In generalists, starvation is hypothesizeddoi:10.1242/jeb.080747 pmid:23197096 fatcat:rpryv7zt6vgz5pwuoq6z7uo47m
