New paper: life-history trade-offs of oviparity and viviparity
Congratulations to Hans and our newest paper - "Differential reproductive investment in co-occurring oviparous and viviparous common lizards ( Zootoca vivipara ) and implications for life-history trade-offs with viviparity". A strength of this study is that it compares oviparity and viviparity reproduction from within the same geographic area and between sister lineages, therefore minimising the effects of environment and phylogeny. The paper is available open access from here, in Oecologia https://rdcu.be/bAGx7 Abstract Live-bearing reproduction (viviparity) has evolved from egg-laying (oviparity) independently many times and most abun-dantly in squamate reptiles. Studying life-history trade-offs between the two reproductive modes is an inherently difficult task, as most transitions to viviparity are evolutionarily old and/or are confounded by environmental effects. The common lizard ( Zootoca vivipara ) is one of very few known reproductively bimodal species, in which...
