title: Replication Data for: Defense Cooperation Agreements and the Emergence of a Global Security Network

description: Bilateral defense cooperation agreements, or DCAs, are now the most common form of institutionalized defense cooperation. These formal agreements establish broad defense-oriented legal frameworks between signatories, facilitating cooperation in such fundamental areas as defense policy coordination, research and development, joint military exercises, education and training, arms procurement, and exchange of classified information. Although nearly a thousand DCAs are currently in force, with potentially wide-ranging impacts on national and international security outcomes, DCAs have been largely ignored by scholars. Why have DCAs proliferated? I develop a theory that integrates cooperation theory with insights from social network analysis. Shifts in the global security environment since the 1980s have fueled demand for DCAs. States use DCAs to modernize their militaries, respond to shared security threats, and establish security umbrellas with like-minded states. Yet, demand alone cannot explain DCA proliferation; to cooperate, governments must also overcome dilemmas of mistrust and distributional conflicts. I show that network influences increase the supply of DCAs by providing governments with information about the trustworthiness of partners and the risk of asymmetric distributions of gains. DCAs become easier to sign as more states sign them. I identify two specific network influences—preferential attachment and triadic closure—and show that these influences are largely responsible for the post-Cold War diffusion of DCAs. Novel empirical strategies further indicate that these influences derive from the proposed informational mechanism. States use the DCA ties of others to glean information about prospective defense partners, thus endogenously fueling further growth of the global DCA network.

title: Replication data for: Using Maimonides' Rule to Estimate the Effect of Class Size on Student Achievement

description: The twelfth century rabbinic scholar Maimonides proposed a maximum class size of 40. This same maximum induces a nonlinear and nonmonotonic relationship between grade enrollment and class size in Israeli public schools today. Maimonides' rule of 40 is used here to construct instrumental variables estimates of effects of class size on test scores. The resulting identification strategy can be viewed as an application of Donald Campbell's regression-discontinuity design to the class-size question. The estimates show that reducing class size induces a significant and substantial increase in test scores for fourth and fifth graders, although not for third graders.

title: Data from: Biomechanical and leaf-climate relationships: a comparison of ferns and seed plants

description: Premise of the study: Relationships of leaf size and shape (physiognomy)
 with climate have been well characterized for woody non-monocotyledonous
 angiosperms (dicots), allowing the development of models for estimating
 paleoclimate from fossil leaves. More recently, petiole width of seed
 plants has been shown to scale closely with leaf mass. By measuring
 petiole width and leaf area in fossils, leaf mass per area (MA) can be
 estimated and an approximate leaf life span inferred. However, little is
 known about these relationships in ferns, a clade with a deep fossil
 record and with the potential to greatly expand the applicability of these
 proxies. Methods: We measured the petiole width, MA, and leaf physiognomic
 characters of 179 fern species from 188 locations across six continents.
 We applied biomechanical models and assessed the relationship between leaf
 physiognomy and climate using correlational approaches. Key results: The
 scaling relationship between area-normalized petiole width and MA differs
 between fern fronds and pinnae. The scaling relationship is best modeled
 as an end-loaded cantilevered beam, which is different from the best-fit
 biomechanical model for seed plants. Fern leaf physiognomy is not
 influenced by climatic conditions. Conclusions: The cantilever beam model
 can be applied to fossil ferns. The lack of sensitivity of leaf
 physiognomy to climate in ferns argues against their use to reconstruct
 paleoclimate. Differences in climate sensitivity and biomechanical
 relationships between ferns and seed plants may be driven by differences
 in their hydraulic conductivity and/or their differing evolutionary
 histories of vein architecture and leaf morphology.

title: Data from: The effects of aging on neuropil structure in mouse somatosensory cortex—A 3D electron microscopy analysis of layer 1

description: This study has used dense reconstructions from serial EM images to compare
 the neuropil ultrastructure and connectivity of aged and adult mice. The
 analysis used models of axons, dendrites, and their synaptic connections,
 reconstructed from volumes of neuropil imaged in layer 1 of the
 somatosensory cortex. This shows the changes to neuropil structure that
 accompany a general loss of synapses in a well-defined brain region. The
 loss of excitatory synapses was balanced by an increase in their size such
 that the total amount of synaptic surface, per unit length of axon, and
 per unit volume of neuropil, stayed the same. There was also a greater
 reduction of inhibitory synapses than excitatory, particularly those found
 on dendritic spines, resulting in an increase in the excitatory/inhibitory
 balance. The close correlations, that exist in young and adult neurons,
 between spine volume, bouton volume, synaptic size, and docked vesicle
 numbers are all preserved during aging. These comparisons display features
 that indicate a reduced plasticity of cortical circuits, with fewer, more
 transient, connections, but nevertheless an enhancement of the remaining
 connectivity that compensates for a generalized synapse loss.

title: Data from: Dispersal evolution in the presence of Allee effects can speed up or slow down invasions

description: Successful invasions by sexually reproducing species depend on the ability
 of individuals to mate. Finding mates can be particularly challenging at
 low densities (a mate-finding Allee effect), a factor that is only
 implicitly accounted for by most invasion models, which typically assume
 asexual populations. Existing theory on single-sex populations suggests
 that dispersal evolution in the presence of a mate-finding Allee effect
 slows invasions. Here we develop a two-sex model to determine how mating
 system, strength of an Allee effect, and dispersal evolution influence
 invasion speed. We show that mating system differences can dramatically
 alter the spread rate. We also find a broader spectrum of outcomes than
 earlier work suggests. Allowing dispersal to evolve in a spreading context
 can sometimes alleviate the mate-finding Allee effect and slow the rate of
 spread. However, we demonstrate the opposite when resource competition
 among females remains high: evolution then acts to speed up the spread
 rate, despite simultaneously exacerbating the Allee effect. Our results
 highlight the importance of the timing of mating relative to dispersal and
 the strength of resource competition for consideration in future empirical
 studies.

title: Data from: Redescription of Phymolepis cuifengshanensis (Antiarcha: Yunnanolepididae) using high-resolution computed tomography and new insights into anatomical details of the endocranium in antiarchs

description: Background. Yunnanolepidoids constitute either the basal-most consecutive
 segments or the most primitive clade of antiarchs, a highly diversified
 jawed vertebrate group from the Silurian and Early Devonian periods.
 Although the general morphology of yunnanolepidoids is well established,
 their endocranial features remain largely unclear, thus hindering our
 further understanding of antiarch evolution, and early gnathostome
 evolution. Phymolepis cuifengshanensis, a yunnanolepidoid from the Early
 Devonian of southwestern China, is re-described in detail to reveal the
 information on endocranial anatomy and additional morphological data of
 head and trunk shields. Methods. We scanned the material of P.
 cuifengshanensis using high-resolution computed tomography and generated
 virtual restorations to show the internal morphology of its dermal shield.
 The dorsal aspect of endocranium in P. cuifengshanensis was therefore
 inferred. The phylogenetic analysis of antiarchs was conducted based on a
 revised and expanded dataset that incorporates ten new cranial characters.
 Results. The lateroventral fossa of trunk shield and Chang's
 apparatus are three-dimensionally restored in P. cuifengshanensis. The
 canal that is positioned just anterior to the internal cavity of
 Chang's apparatus, probably corresponds to the rostrocaudal canal of
 euantiarchs. The endocranial morphology of P. cuifengshanensis
 corroborates a general pattern for yunnanolepidoids with additional
 characters distinguishing them from sinolepids and euantiarchs, such as a
 developed cranio-spinal process, an elongated endolymphatic duct, and a
 long occipital portion. Discussion. In light of new data from Phymolepis
 and Yunnanolepis, we summarized the morphology on the visceral surface of
 head shield in antiarchs, and formulated additional ten characters for the
 phylogenetic analysis. These cranial characters exhibit a high degree of
 morphological disparity between major subgroups of antiarchs, and
 highlight the endocranial character evolution in antiarchs.

title: Data from: Identifying homomorphic sex chromosomes from wild-caught adults with limited genomic resources

description: We demonstrate a genotyping-by-sequencing approach to identify homomorphic
 sex chromosomes and their homolog in a distantly related reference genome,
 based on noninvasive sampling of wild-caught individuals, in the moor frog
 Rana arvalis. Double-digest RADseq libraries were generated using buccal
 swabs from 30 males and 21 females from the same population. Search for
 sex-limited markers from the unfiltered data set (411 446 RAD tags) was
 more successful than searches from a filtered data set (33 073 RAD tags)
 for markers showing sex differences in heterozygosity or in allele
 frequencies. Altogether, we obtained 292 putatively sex-linked RAD loci,
 98% of which point to male heterogamety. We could map 15 of them to the
 Xenopus tropicalis genome, all but one on chromosome pair 1, which seems
 regularly co-opted for sex determination among amphibians. The most
 efficient mapping strategy was a three-step hierarchical approach, where
 R. arvalis reads were first mapped to a low-coverage genome of Rana
 temporaria (17 My divergence), then the R. temporaria scaffolds to the
 Nanorana parkeri genome (90 My divergence), and finally the N. parkeri
 scaffolds to the X. tropicalis genome (210 My). We validated our
 conclusions with PCR primers amplifying part of Dmrt1, a candidate sex
 determination gene mapping to chromosome 1: a sex-diagnostic allele was
 present in all 30 males but in none of the 21 females. Our approach is
 likely to be productive in many situations where biological samples and/or
 genomic resources are limited.

title: Data from: Microbe biogeography tracks water masses in a dynamic oceanic frontal system

description: PLEASE NOTE, THESE DATA ARE ALSO REFERRED TO IN ANOTHER PUBLICATION.
 PLEASE SEE http://dx.doi.org/10.1098/rsos.160829. Dispersal limitation,
 not just environmental selection, plays an important role in microbial
 biogeography. The distance–decay relationship is thought to be weak in
 habitats where dispersal is high, such as in the pelagic environment,
 where ocean currents facilitate microbial dispersal. Most studies of
 microbial community composition to date have observed little geographical
 heterogeneity on a regional scale (100 km). We present a study of
 microbial communities across a dynamic frontal zone in the southwest
 Indian Ocean and investigate the spatial structure of the microbes with
 respect to the different water masses separated by these fronts. We
 collected 153 samples of free-living microorganisms from five seamounts
 located along a gradient from subtropical to subantarctic waters and
 across three depth layers: (i) the sub-surface chlorophyll maximum
 (approx. 40 m), (ii) the bottom of the euphotic zone (approx. 200 m), and
 (iii) the benthic boundary layer (300–2000 m). Diversity and abundance of
 microbial operational taxonomic units (OTUs) were assessed by
 amplification and sequencing of the 16S rRNA gene on an Illumina MiSeq
 platform. Multivariate analyses showed that microbial communities were
 structured more strongly by depth than by latitude, with similar phyla
 occurring within each depth stratum across seamounts. The deep layer was
 homogeneous across the entire survey area, corresponding to the spread of
 Antarctic intermediate water. However, within both the sub-surface layer
 and the intermediate depth stratum there was evidence for OTU turnover
 across fronts. The microbiome of these layers appears to be divided into
 three distinct biological regimes corresponding to the subantarctic
 surface water, the convergence zone and subtropical. We show that
 microbial biogeography across depth and latitudinal gradients is linked to
 the water masses the microbes persist in, resulting in regional patterns
 of microbial biogeography that correspond to the regional scale physical
 oceanography.

title: Data from: PCR duplication: a one-step cloning-free method to generate duplicated chromosomal loci and interference-free expression reporters in yeast

description: Here, we report on a novel PCR targeting-based strategy called ‘PCR
 duplication’ that enables targeted duplications of genomic regions in the
 yeast genome using a simple PCR-based approach. To demonstrate its
 application we first duplicated the promoter of the FAR1 gene in yeast and
 simultaneously inserted a GFP downstream of it. This created a reporter
 for promoter activity while leaving the FAR1 gene fully intact. In another
 experiment, we used PCR duplication to increase the dosage of a gene in a
 discrete manner, from 1× to 2x. Using TUB4, the gene encoding for the
 yeast γ-tubulin, we validated that this led to corresponding increases in
 the levels of mRNA and protein. PCR duplication is an easy one-step
 procedure that can be adapted in different ways to permit rapid,
 disturbance-free investigation of various genomic regulatory elements
 without the need for ex vivo cloning.
