Data from: Cryptic genetic diversity is paramount in small-bodied amphibians of the genus Euparkerella (Anura: Craugastoridae) endemic to the Brazilian Atlantic Forest
Morphological similarity associated to restricted distributions and low dispersal abilities make the direct developing "Terrarana" frogs of the genus Euparkerella a good model for examining diversification processes. We here infer phylogenetic relationships within the genus Euparkerella, using DNA sequence data from one mitochondrial and four nuclear genes coupled with traditional Bayesian phylogenetic reconstruction approaches and more recent coalescent methods of species tree inference. We also used Bayesian clustering analysis and a recent Bayesian coalescent-based approach specifically to infer species delimitation. The analysis of 39 individuals from the four known Euparkerella species uncovered high levels of genetic diversity, especially within the two previously morphologically-defined E. cochranae and E. brasiliensis. Within these species, the gene trees at five independent loci and trees from combined data (concatenated dataset and the species tree) uncovered six deeply diverged and geographically coherent evolutionary units, which may have diverged between the Miocene and the Pleistocene. These six units were also uncovered in the Bayesian clustering analysis, and supported by the Bayesian coalescent-based species delimitation (BPP), and Genealogical Sorting Index (GSI), providing thus strong evidence for underestimation of the current levels of diversity within Euparkerella. The cryptic diversity now uncovered opens new opportunities to examine the origins and maintenance of microendemism in the context of spatial heterogeneity and/or human induced fragmentation of the highly threatened Brazilian Atlantic forest hotspot.
Data from: Senescence or selective disappearance? Age trajectories of body mass in wild and captive populations of a small-bodied primate
Classic theories of ageing consider extrinsic mortality (EM) a major factor in shaping longevity and ageing, yet most studies of functional ageing focus on species with low EM. This bias may cause overestimation of the influence of senescent declines in performance over condition-dependent mortality on demographic processes across taxa. To simultaneously investigate the roles of functional senescence (FS) and intrinsic, extrinsic and condition-dependent mortality in a species with a high predation risk in nature, we compared age trajectories of body mass (BM) in wild and captive grey mouse lemurs (Microcebus murinus) using longitudinal data (853 individuals followed through adulthood). We found evidence of non-random mortality in both settings. In captivity, the oldest animals showed senescence in their ability to regain lost BM, whereas no evidence of FS was found in the wild. Overall, captive animals lived longer, but a reversed sex bias in lifespan was observed between wild and captive populations. We suggest that even moderately condition-dependent EM may lead to negligible FS in the wild. While high EM may act to reduce the average lifespan, this evolutionary process may be counteracted by the increased fitness of the long-lived, high-quality individuals.

The coat color is pale ocher, with brownish or grayish tones; melanistic individuals are quite common. The throat and chest are blackish, and the ventral pelage varies from creamy white to dirty white. The stripes and spots on the body vary from different hues of brown to black. The nuchal stripes run as two parallel lines from the nape to the shoulders, where they diverge and enlarge towards the elbows; they are not so conspicuously marked as in other genet species. Below them, a pair of thinner stripes and small spots are scattered on the shoulders and sides of the neck. A third pair of thinner, parallel stripes runs down the neck between the nuchal stripes, extending to about one fourth of the mid-dorsal line, where they vanish or diverge as the first row of flank spots. The black mid-dorsal line is continuous and is flanked on each side by four rows of oblong to squared spots, and by a few small-scattered spots below. There is a dorsal erectile crest. The face has a dark mask and a pair of white sub-ocular spots. The tail has seven to nine black rings, alternating with pale rings; the intervening white spaces are pigmented with a brownish tinge on the dorsal midline. The width of the pale rings relative to the dark rings in the middle of the tail is 50-75%; the tip of the tail is dark. The hindlimbs and forelimbs are black; there are white hairs on the metacarpals and metatarsals. [he posterior parts of the feet are dark. There are two pairs of teats. The posterior chamber of the auditory bulla is not ventrally inflated and has a continuous curve line on the external side. The ratio between the inter-orbital constriction and frontal width is 1-00 + 0-12. Dental formula: 13/3, C1/1,P 4/4, M 2/2 = 40. in Viverridae

Histological and life history data for small-bodied mammals from: Multituberculate mammals show evidence of a life history strategy similar to that of placentals, not marsupials
<p>The remarkable evolutionary success of placental mammals has been partly attributed to their reproductive strategy of prolonged gestation and birthing of relatively precocial, quickly weaned neonates. Although this strategy was conventionally considered derived relative to that of marsupials with highly altricial neonates and long lactation periods, mounting evidence has challenged this view. Until now, the fossil record has been relatively silent on this debate, but here we find that proportions of different bone tissue microstructures in the femoral cortices of small extant marsupials and placentals correlate with length of lactation period, allowing us to apply this histological correlate of reproductive strategies to Late Cretaceous and Paleocene members of Multituberculata, an extinct mammalian clade that is phylogenetically stemward of Theria. Multituberculate bone histology closely resembles that of placentals, suggesting that they had similar life history strategies. That a stem-therian clade exhibits evidence of placental-like life histories supports the hypothesis that intense maternal-fetal contact characteristic of placentals is ancestral for therians. Alternatively, multituberculates and placentals may have independently evolved prolonged gestation and abbreviated lactation periods. Our results challenge the hypothesis that the rise of placental mammals was driven by unique life history innovations, and shed new light on early mammalian diversification.</p>
