Data for: Convergence and contingency in the evolution of a specialized mode of life: Multiple origins and high disparity of rock-boring bivalves
<p>Evolutionary adaptation to novel, specialized modes of life is often associated with close mapping of form to function, resulting in narrow morphological disparity. For Bivalvia, endolithy (rock-boring) has biomechanical requirements thought to diverge strongly from those of the ancestral shallow-burrowing habit in soft sediments. However, 3D morphometric data from 73 species among ~94% of extant endolithic genera and families, along with 384 non-endolithic species in those families, show that endolithy has originated at least eight times. Endolithy is evolutionarily accessible from multiple morphological starting points, evidenced by the morphologies of the oldest fossil members of families. Although some endoliths appear to converge on a limited set of shell morphologies, the total range of endolith shell morphologies among the broadest for bivalve life habits, and lacks any unifying morphological trait. Nevertheless, endolithy is a taxon-poor habit today. This limited richness evidently does not derive from damped origination or heightened extinction rates on lineages containing endoliths, and today's endoliths are not confined to low diversity biogeographic regions. Instead, endolithy may be limited by habitat availability. Both determinism (convergence among distantly related taxa) and contingency (endoliths remain close to the disparate morphologies of their source clades) underlie the occupation of endolith morphospace.</p>
The origin of blinking in both mudskippers and tetrapods is linked to life on land
<p>Blinking, the transient occlusion of the eye by one or more membranes, serves several functions including wetting, protecting, and cleaning the eye. This behavior is seen in nearly all living tetrapods and absent in other extant sarcopterygian lineages, suggesting that it might have arisen during the water-to-land transition. Unfortunately, our understanding of the origin of blinking has been limited by a lack of known anatomical correlates of the behavior in the fossil record and a paucity of comparative functional studies. To understand how and why blinking originates, we leverage mudskippers (Oxudercinae), a clade of amphibious fishes that have convergently evolved blinking. Using micro-computed tomography and histology, we analyzed two mudskipper species, <em>Periophthalmus</em> <em>barbarus</em> and <em>Periophthalmodon</em> <em>septemradiatus</em>, and compared them to the fully aquatic round goby, <em>Neogobius</em> <em>melanostomus</em>. Study of gross anatomy and epithelial microstructure shows that mudskippers have not evolved novel musculature or glands to blink. Behavioral analyses show the blinks of mudskippers are functionally convergent with those of tetrapods: <em>P. barbarus</em> blinks more often under high evaporation conditions to wet the eye, a blink reflex protects the eye from physical insult, and a single blink can fully clean the cornea of particulates. Thus, eye retraction in concert with a passive occlusal membrane can achieve functions associated with life on land. Osteological correlates of eye retraction are present in the earliest limbed vertebrates, suggesting blinking capability. In both mudskippers and tetrapods, therefore, the origin of this multifunctional innovation is likely explained by selection for increasingly terrestrial lifestyles.</p>

Data from: Reconstructing the origins of high-alpine niches and cushion life form in the genus Androsace s.l. (Primulaceae)
Relatively few species have been able to colonize extremely cold alpine environments. We investigate the role played by the cushion life form in the evolution of climatic niches in the plant genus Androsace s.l., which spreads across the mountain ranges of the Northern Hemisphere. Using robust methods that account for phylogenetic uncertainty, intraspecific variability of climatic requirements and different life history evolution scenarios, we show that climatic niches of Androsace s.l. exhibit low phylogenetic signal and that they evolved relatively recently and punctually. Models of niche evolution fitted onto phylogenies show that the cushion life form has been a key innovation providing the opportunity to occupy extremely cold environments, thus contributing to rapid climatic niche diversification in the genus Androsace. We then propose a plausible scenario for the adaptation of plants to alpine habitats.
