Understanding the response of permafrost microbial communities to climate warming is crucial for evaluating ecosystem feedbacks to global change. This study investigated soil bacterial and archaeal communities by Illumina MiSeq sequencing of 16S rRNA gene amplicons across a permafrost thaw gradient at different depths in Alaska with thaw progression for over three decades. Over 4.6 million passing 16S rRNA gene sequences were obtained from a total of 97 samples, corresponding to 61 known classes and...

Data from: Global phylogenetic structure of the hyperdiverse ant genus Pheidole reveals the repeated evolution of macroecological patterns

Evan P. Economo, Pavel Klimov, Eli M. Sarnat, Benoit Guénard, Michael D. Weiser, Beatrice Lecroq, L. Lacey Knowles & B. Guenard
Adaptive radiations are of particular interest owing to what they reveal about the ecological and evolutionary regulation of biodiversity. This applies to localized island radiations such as Darwin's finches, and also to rapid radiations occurring on a global scale. Here we analyse the macroevolution and macroecology of Pheidole, a famously hyperdiverse and ecologically dominant ant genus. We generate and analyse four novel datasets: (i) a robust global phylogeny including 285 Pheidole species, (ii) a global...

Data from: Beyond surrogacy: A multi-taxon approach to conservation biogeography

Brenda D. Smith-Patten & Michael A. Patten
Biogeographic analysis of species turnover (β diversity) of plants and animals among regions often yields conflicting results, with regions of high β diversity identified for some taxonomic groups but not others. Such discordance calls into question use of surrogate taxa to forge conservation plans. This discordance begs for a means of comparing multiple taxa across phyla in a manner that is cost-effective, considers limitations in computer resources in certain global regions, and is understood by...

Data from: Multilocus phylogeny and a new classification for Southeast Asian and Melanesian forest frogs (family Ceratobatrachidae)

Rafe M. Brown, Cameron D. Siler, Stephen J. Richards, Arvin C. Diesmos & David C. Cannatella
We present a near comprehensive, densely sampled, multilocus phylogenetic estimate of species relationships within the anuran family Ceratobatrachidae, a morphologically and ecologically diverse group of frogs from the island archipelagos of Southeast Asia and the South-West Pacific. Ceratobatrachid frogs consist of three clades: a small clade of enigmatic, primarily high-elevation, semi-aquatic Sundaland species currently assigned to Ingerana (for which we erect a new genus), which is the sister taxon of two large, monophyletic radiations, each...

Data from: Conservation genetics of the Philippine tarsier: cryptic genetic variation restructures conservation priorities for an island archipelago primate

Rafe M. Brown, Jennifer A. Weghorst, Karen V. Olson, Mariano R. M. Duya, Anthony J. Barley, Melizar V. Duya, Myron Shekelle, Irene Neri-Arboleda, Jacob A. Esselstyn, Nathaniel J. Dominy, Perry S. Ong, Gillian L. Moritz, Adrian Luczon, Mae Lowe L. Diesmos, Arvin C. Diesmos & Cameron D. Siler
Establishment of conservation priorities for primates is a particular concern in the island archipelagos of Southeast Asia, where rates of habitat destruction are among the highest in the world. Conservation programs require knowledge of taxonomic diversity to ensure success. The Philippine tarsier is a flagship species that promotes environmental awareness and a thriving ecotourism economy in the Philippines. However, assessment of its conservation status has been impeded by taxonomic uncertainty, a paucity of field studies,...

Data from: Rapid morphological divergence of a stream fish in response to changes in water flow

, Richard E. Broughton & J. C. Cureton
Recent evidence indicates that evolution can occur on a contemporary time scale. However, the precise timing and patterns of phenotypic change are not well known. Reservoir construction severely alters selective regimes in aquatic habitats due to abrupt cessation of water flow. We examined the spatial and temporal patterns of evolution of a widespread North American stream fish (Pimephales vigilax) in response to stream impoundment. Gross morphological changes occurred in P. vigilax populations following dam construction...

Data from: Asymmetric mismatch in strain-specific genital morphology causes increased harm to Drosophila females

John P. Masly & Yoshitaka Kamimura
Although several evolutionary forces have been proposed to contribute to genital morphological diversification, it is unclear which might act early during the evolution of novel structural traits. We test the hypothesis that mismatch between interacting male and female secondary sexual structures gives rise to increased harm to females, consistent with the outcome predicted from a history of sexual conflict. We mate Drosophila sechellia females to males from a collection of D. mauritiana-D. sechellia interspecific genetic...

Data from: Inferring outcrossing in the homothallic fungus Sclerotinia sclerotiorum using linkage disequilibrium decay

Weidong Chen, Renuka N. Attanayake, Vidhura Tennekoon, Dennis A. Johnson, Lyndon D. Porter, Luis Del Río-Mendoza & Daohong Jiang
The occurrence and frequency of outcrossing in homothallic fungal species in nature is an unresolved question. Here we report detection of frequent outcrossing in the homothallic fungus Sclerotinia sclerotiorum. In using multilocus linkage disequilibrium (LD) to infer recombination among microsatellite alleles, high mutation rates confound the estimates of recombination. To distinguish high mutation rates from recombination to infer outcrossing, 8 population samples comprising 268 S. sclerotiorum isolates from widely distributed agricultural fields were genotyped for...

Data from: Selection from parasites favors immunogenetic diversity but not divergence among locally adapted host populations

Michael Tobler, Martin Plath, Rüdiger Riesch, Ingo Schlupp, Anna Grasse, Gopi K. Munimanda, Claudia Setzer, Dustin J. Penn & Yoshan Moodley
The unprecedented polymorphism in the major histocompatibility complex (MHC) genes is thought to be maintained by balancing selection from parasites. However, do parasites also drive divergence at MHC loci between host populations, or do the effects of balancing selection maintain similarities among populations? We examined MHC variation in populations of the livebearing fish Poecilia mexicana and characterized their parasite communities. Poecilia mexicana populations in the Cueva del Azufre system are locally adapted to darkness and...

Data from: Long-term balanced fertilization improves the soil microbial functional diversity in a phosphorus-limited paddy soil

Jian-Qiang Su, Long-Jun Ding, Kai Xue, Huai-Ying Yao, John Quensen, Shi-Jie Bai, Wen-Xue Wei, Jin-Shui Wu, Jizhong Zhou, James M. Tiedje & Yong-Guan Zhu
The influence of long-term chemical fertilization on soil microbial communities has been one of the frontier topics of agricultural and environmental sciences and is critical for linking soil microbial flora with soil functions. In this study, 16S rRNA gene pyrosequencing and a functional gene array, GeoChip 4.0, were used to investigate the shifts in microbial composition and functional gene structure in paddy soils with different fertilization treatments over a 22-year period. These included a control...

Data from: Partner switching can favor cooperation in a biological market

P. L. Schwagmeyer
Intraspecific cooperation and interspecific mutualisms can be promoted by mechanisms that reduce the frequency with which cooperative organisms are exploited by unhelpful partners. One such mechanism consists of changing partners after interacting with an uncooperative individual. I used McNamara et al.'s (Nature, 451, 2008, 189) partner switching model as a framework to examine whether this mechanism can select for increased cooperative investment by house sparrows (Passer domesticus) collaborating to rear offspring; previous research on this...
