Data from: Longevity, body dimension and reproductive mode drive differences in aquatic versus terrestrial life history strategies
<p>1. Aquatic and terrestrial environments display stark differences in key environmental factors and phylogenetic composition but their consequences for the evolution of species' life history strategies remain poorly understood.</p> <p>2. Here, we examine whether and how life history strategies vary between terrestrial and aquatic species. We use demographic information for 685 terrestrial and 122 aquatic animal and plant species to estimate key life history traits. We then use phylogenetically corrected least squares regression to explore potential differences in trade-offs between life history traits between both environments. We contrast life history strategies of aquatic vs. terrestrial species in a principal component analysis while accounting for body dimensions and phylogenetic relationships.</p> <p>3. Our results show that the same trade-offs structure terrestrial and aquatic life histories, resulting in two dominant axes of variation that describe species' pace-of-life and reproductive strategies. Terrestrial plants display a large diversity of strategies, including the longest-lived species in this study. Aquatic animals exhibit higher reproductive frequency than terrestrial animals. When correcting for body size, mobile and sessile terrestrial organisms show slower paces of life than aquatic ones.</p> <p>4. Aquatic and terrestrial species are ruled by the same life history trade-offs, but have evolved different strategies, likely due to distinct environmental selective pressures. Such contrasting life history strategies have important consequences for the conservation and management of aquatic and terrestrial species.</p>

Data from: Forests as promoters of terrestrial life history strategies in East African amphibians
Many amphibian lineages show terrestrialization of their reproductive strategy and breeding is partially or completely independent of water. A number of causal factors have been proposed for the evolution of terrestrialized breeding. While predation has received repeated attention as a potential factor, the influence of others such as habitat has never been tested using appropriate data or methods. Using a dataset that comprises 180 amphibian species from various East African habitats, we tested whether species occurring in different habitats show different patterns of terrestrialization in their breeding strategy. We recovered a significant association between terrestrialized breeding strategies and forest habitats. In general, forest seems to act as a facilitator, providing a permissive environment for the evolution of terrestrialized breeding strategies. However, while terrestrial oviposition is strongly correlated with lowland and montane forest habitat, complete terrestrial development is significantly correlated with montane forest only, indicating different selective pressures acting at different steps towards complete terrestrial development.
