Data from: When males outlive females: sex-specific effects of temperature on lifespan in a cyclic parthenogen

Barbara Pietrzak, Małgorzata Grzesiuk, Julia Dorosz & Andrzej Mikulski
Lifespans of males and females frequently differ as a consequence of different life history strategies adopted to maximize fitness. It is well visible in cyclic parthenogens, such as water fleas of the genus Daphnia, where males appear in the population usually only for periods when receptive females are available. Moreover, even within one sex, different life history strategies and mechanisms regulating lifespan may exist. Previous studies suggested that Daphnia males may regulate their lifespan by...

Data from: The early composition and evolution of the turtle shell (Reptilia, Testudinata)

Tomasz Szczygielski & Tomasz Sulej
The shell of the oldest true turtle (Testudinata) branch (Proterochersidae) from the Late Triassic (Norian) of Poland and Germany was built in its anterior and posterior part from an osteodermal mosaic which developed several million years after the plastron, neurals, and costal bones. The most detailed description of the shell composition in proterochersids thus far is provided together with a review of the shell composition in other Triassic pantestudinates, the scenario of early evolution of...

Data from: An exceptionally preserved Jurassic skink suggests lizard diversification preceded fragmentation of Pangaea

Mateusz Tałanda
The present distribution of lizards is usually explained as a result of relatively recent global events, i.e. faunal turnovers or exchanges within and between particular continents mostly connected with glaciations and land-bridges. However, today’s disjunct distribution of the North American Xantusiidae and African Cordyliformes (close relatives of skinks) does not fit generally accepted biogeographic patterns. A new exquisitely preserved specimen of the Late Jurassic lizard Ardeosaurus brevipes from the Solnhofen area, Germany sheds some light...

Data from: Long term effects of superoxide and DNA repair on lizard telomeres

Mats Olsson, Christopher R. Friesen, Nicky Rollings, Joanna Sudyka, Willow Lindsay, Camilla M. Whittington & Mark Wilson
Telomeres are the non-coding protein-nucleotide ‘caps’ at chromosome ends that contribute to chromosomal stability by protecting the coding parts of the linear DNA from shortening at cell division, and from erosion by reactive molecules. Recently, there has been some controversy between molecular and cell biologists, on the one hand, and evolutionary ecologists on the other, regarding whether reactive molecules erode telomeres during oxidative stress. Many studies of biochemistry and medicine have verified these relationships in...
