Data from: Phylogeny and generic delimitation in Molluginaceae, new pigment data in Caryophyllales, and the new family Corbichoniaceae

Mats Thulin, Abigail J. Moore, Hesham El-Seedi, Anders Larsson, Pascal-Antoine Christin & Erika J. Edwards
The circumscription of Molluginaceae has changed radically in recent years, with Corbichonia being moved to Lophiocarpaceae, Limeum to Limeaceae, Macarthuria to Macarthuriaceae and all species of Hypertelis, except the type, to Kewa in Kewaceae. In a broad analysis of core Caryophyllales using plastid trnK-matK and rbcL sequences, the position of Molluginaceae in a strict sense as sister to the Portulacineae clade is corroborated, as are the positions of Corbichonia, Limeum and Kewa outside the family....

Data from: Species-habitat relationships and ecological correlates of butterfly abundance in a transformed tropical landscape

Anuj Jain, Felix K. S. Lim & Edward L. Webb
Tropical butterfly conservation strategies often focus on total and/or common species richness to assess the conservation value of a patch or habitat. However, such a strategy overlooks the unique dynamics of rare species. We evaluated the species-habitat relationships of 209 common, intermediate, and rare butterfly species (including morphospecies) across four habitat types (mature, degraded, or fragmented forest, and urban parks) and two patch sizes (<400 ha, ≥400 ha) in Singapore. Common species richness was consistent...

Data from: Stabilising survival selection on pre-senescent expression of a sexual ornament followed by a terminal decline

Mirre Simons, Michael Briga, Simon Verhulst & M. J. P. Simons
Senescence is a decrease in functional capacity, increasing mortality rate with age. Sexual signals indicate functional capacity, because costs of ornamentation ensure signal honesty, and are therefore expected to senesce, tracking physiological deterioration and mortality. For sexual traits, mixed associations with age and positive associations with life expectancy have been reported. However, whether these associations are caused by selective disappearance and/or within-individual senescence of sexual signals, respectively, is not known. We previously reported that zebra...

Autotrophic and heterotrophic soil respiration fluxes from peatland plateaus and thawing peatland plateaus and from burnt and unburnt forests from permafrost in subarctic Canada

Monitored sites included peatland plateaus, unburnt and burnt black spruce forests, and additional sites.

Data from: Reframing the evidence base for policy-relevance to increase impact: a case study on forest fragmentation in the oil palm sector

Jennifer M. Lucey, Georgina Palmer, K. Loong Yeong, David P. Edwards, Michael J. M. Senior, Sarah A. Scriven, Glen Reynolds & Jane K. Hill
It is necessary to improve knowledge exchange between scientists and decision-makers so that scientific evidence can be readily accessed to inform policy. To maximise impact of scientific evidence in policy development, the scientific community should engage more fully with decision-makers, building long-term working relationships in order to identify and respond to ‘policy windows’ with science that is reframed for policy-relevance. We illustrate the process and challenges using a case study in which we synthesised evidence...

Data from: The impact of tropical forest logging and oil palm agriculture on the soil microbiome

Binu M. Tripathi, David P. Edwards, Lucas William Mendes, Mincheol Kim, Ke Dong, Hyoki Kim & Jonathan M. Adams
Selective logging and forest conversion to oil palm agriculture are rapidly altering tropical forests. However, functional responses of the soil microbiome to these land-use changes are poorly understood. Using 16S rRNA gene and shotgun metagenomic sequencing, we compared composition and functional attributes of soil biota between unlogged, once-logged and twice-logged rainforest, and areas converted to oil palm plantations in Sabah, Borneo. Although there was no significant effect of logging history, we found a significant difference...

Data from: Winter territory prospecting is associated with life-history stage but not activity in a passerine

Alfredo Sánchez-Tójar, Isabel Winney, Antje Girndt, Mirre J.P. Simons, Shinichi Nakagawa, Terry Burke, Julia Schroeder & Mirre J. P. Simons
Finding a high quality territory is essential for many animals to reproduce successfully. Despite its importance for fitness, we know little about the process of territory prospecting in wild birds, and whether individual traits and behaviours, such as personality, co-vary with territory prospecting. Here, we use long-term data from a wild, insular house sparrow Passer domesticus population to test three hypotheses about territory fidelity and prospecting: (1) House sparrows show high territory fidelity between years...

Data from: Ecological speciation in sympatric palms: 2. pre- and post-zygotic isolation

H. Hipperson, L.T. Dunning, W.J. Baker, R.K. Butlin, I. Hutton, A.S.T. Papadopulos, C.M. Smadja, T.C. Wilson, C. Devaux, Vincent Savolainen, R. K. Butlin, T. C. Wilson, W. J. Baker & A. S. T. Papadopulos
We evaluated reproductive isolation in two species of palms (Howea) that have evolved sympatrically on Lord Howe Island (LHI, Australia). We estimated the strength of some pre- and post-zygotic mechanisms in maintaining current species boundaries. We found that flowering time displacement between species is consistent across in and ex situ common gardens and is thus partly genetically determined. On LHI, pre-zygotic isolation due solely to flowering displacement was 97% for H. belmoreana and 80% for...

Data from: Genome divergence and diversification within a geographic mosaic of coevolution

Thomas L. Parchman, C. Alex Buerkle, Victor Soria-Carrasco & Craig W. Benkman
Despite substantial interest in coevolution's role in diversification, examples of coevolution contributing to speciation have been elusive. Here, we build upon past studies that have shown both coevolution between South Hills crossbills and lodgepole pine (Pinus contorta), and high levels of reproductive isolation between South Hills crossbills and other ecotypes in the North American red crossbill (Loxia curvirostra) complex. We used genotyping by sequencing to generate population genomic data and applied phylogenetic and population genetic...

Data from: Telomere length reveals cumulative individual and transgenerational inbreeding effects in a passerine bird

Kat Bebbington, Lewis G. Spurgin, Eleanor A. Fairfield, Hannah L. Dugdale, Jan Komdeur, Terry Burke & David S. Richardson
Inbreeding results in more homozygous offspring that should suffer reduced fitness, but it can be difficult to quantify these costs for several reasons. First, inbreeding depression may vary with ecological or physiological stress and only be detectable over long time periods. Second, parental homozygosity may indirectly affect offspring fitness, thus confounding analyses that consider offspring homozygosity alone. Finally, measurement of inbreeding coefficients, survival and reproductive success may often be too crude to detect inbreeding costs...

Soil cores were sampled during early summer in 2013 and 2014 from peatland plateaus, thawing peatland plateaus, burnt and unburnt black spruce forests in Yukon and Northwest Territories. The upper part of the soil profile was dated using 210Pb to quantify recent carbon accumulation rates.

Data from: Differential gene expression according to race and host plant in the pea aphid

Isobel Eyres, Julie Jaquiéry, Akiko Sugio, Ludovic Duvaux, Karim Gharbi, Jing-Jiang Zhou, Fabrice Legeai, Michaela Nelson, Jean-Christophe Simon, Carole M. Smadja, Roger Butlin & Julia Ferrari
Host-race formation in phytophagous insects is thought to provide the opportunity for local adaptation and subsequent ecological speciation. Studying gene expression differences amongst host races may help to identify phenotypes under (or resulting from) divergent selection and their genetic, molecular and physiological bases. The pea aphid (Acyrthosiphon pisum) comprises host races specializing on numerous plants in the Fabaceae and provides a unique system for examining the early stages of diversification along a gradient of genetic...

Data from: A universal mechanism generating clusters of differentiated loci during divergence-with-migration

Marina Rafajlović, Anna Emanuelsson, Kerstin Johannesson, Roger K. Butlin & Bernhard Mehlig
Genome-wide patterns of genetic divergence reveal mechanisms of adaptation under gene flow. Empirical data show that divergence is mostly concentrated in narrow genomic regions. This pattern may arise because differentiated loci protect nearby mutations from gene flow, but recent theory suggests this mechanism is insufficient to explain the emergence of concentrated differentiation during biologically realistic timescales. Critically, earlier theory neglects an inevitable consequence of genetic drift: stochastic loss of local genomic divergence. Here, we demonstrate...

Data from: Energy benefits and emergent space use patterns of an empirically parameterized model of memory-based patch selection

Jerod A. Merkle, Jonathan R. Potts & Daniel Fortin
Many species frequently return to previously visited foraging sites. This bias towards familiar areas suggests that remembering information from past experience is beneficial. Such a memory-based foraging strategy has also been hypothesized to give rise to restricted space use (i.e. a home range). Nonetheless, the benefits of empirically derived memory-based foraging tactics and the extent to which they give rise to restricted space use patterns are still relatively unknown. Using a combination of stochastic agent-based...

Data from: InGaAs/InAlAs single photon avalanche diode for 1550 nm photons

Xiao Meng, Shiyu Xie, Xinxin Zhou, Niccolò Calandri, Mirko Sanzaro, Alberto Tosi, Chee Hing Tan & Jo Shien Ng
A single photon avalanche diode (SPAD) with an InGaAs absorption region, and an InAlAs avalanche region was designed and demonstrated to detect 1550 nm wavelength photons. The characterization included leakage current, dark count rate and single photon detection efficiency as functions of temperature from 210 to 294 K. The SPAD exhibited good temperature stability, with breakdown voltage dependence of approximately 45 mV K−1. Operating at 210 K and in a gated mode, the SPAD achieved...

Data from: Widespread correlations between climatic niche evolution and species diversification in birds

Christopher R. Cooney, Nathalie Seddon & Joseph A. Tobias
The adaptability of species’ climatic niches can influence the dynamics of colonisation and gene flow across climatic gradients, potentially increasing the likelihood of speciation, or reducing extinction in the face of environmental change. However, previous comparative studies have tested these ideas using geographically, taxonomically and ecologically restricted samples, yielding mixed results, and thus the processes linking climatic niche evolution with diversification remain poorly understood. Focusing on birds, the largest and most widespread class of terrestrial...

Data from: The colour of paternity: extra-pair paternity in the wild Gouldian finch does not appear to be driven by genetic incompatibility between morphs

Peri E. Bolton, Lee Ann Rollins, James Brazill-Boast, Kang-Wook Kim, Terry Burke, Simon C. Griffith & K-W. Kim
In socially monogamous species, individuals can use extra-pair paternity and offspring sex allocation as adaptive strategies to ameliorate costs of genetic incompatibility with their partner. Previous studies on domesticated Gouldian finches (Erythrura gouldiae) demonstrated a genetic incompatibility between head colour morphs, the effects of which are more severe in female offspring. Domesticated females use differential sex allocation, and extra-pair paternity with males of compatible head colour, to reduce fitness costs associated with incompatibility in mixed-morph...

Data from: Multi-alternative decision making with non-stationary inputs

Luana F. Nunes & Kevin Gurney
One of the most widely implemented models for multi-alternative decision-making is the multihypothesis sequential probability ratio test (MSPRT). It is asymptotically optimal, straightforward to implement, and has found application in modelling biological decision-making. However, the MSPRT is limited in application to discrete (‘trial-based’), non-time-varying scenarios. By contrast, real world situations will be continuous and entail stimulus non-stationarity. In these circumstances, decision-making mechanisms (like the MSPRT) which work by accumulating evidence, must be able to discard...

Data from: Managing cryptic biodiversity: Fine-scale intralacustrine speciation along a benthic gradient in Alpine whitefish (Coregonus spp.)

Alan G. Hudson, Baenz Lundsgaard-Hansen, Kay Lucek, Pascal Vonlanthen & Ole Seehausen
Whitefish (Coregonus spp.) are an important catch for many freshwater fisheries, particularly in Switzerland. In support of this, supplemental stocking of whitefish species is carried out, despite lacking complete knowledge of the extent, distribution and origin of whitefish diversity in these lakes, potentially threatening local endemics via artificial gene flow. Here, we investigate phenotypic and genetic differentiation among coexisting whitefish species spawning along a depth gradient in a subalpine Swiss lake to better delineate intralacustrine...

Data from: The stable isotope ecology of mycalesine butterflies: implications for plant-insect co-evolution

Erik Van Bergen, Henry S. Barlow, Oskar Brattström, Howard Griffiths, Ullasa Kodandaramaiah, Colin P. Osborne & Paul M. Brakefield
One of the most dramatic examples of biome shifts in the geological record is the rapid replacement of C3 vegetation by C4 grasses in (sub-) tropical regions during the Late Miocene–Pliocene. Climate-driven biome shifts of this magnitude are expected to have a major impact on diversification and ecological speciation, especially in grazing taxa. Mycalesine butterflies are excellent candidates to explore the evolutionary impact of these C3/C4 shifts on insect grazer communities. Mycalesine butterflies feed on...

Data from: Extremophile Poeciliidae: multivariate insights into the complexity of speciation along replicated ecological gradients

Rüdiger Riesch, Michael Tobler, Hannes Lerp, Jonas Jourdan, Tess Doumas, Patrik Nosil, R. Brian Langerhans & Martin Plath
Background: Replicate population pairs that diverge in response to similar selective regimes allow for an investigation of (a) whether phenotypic traits diverge in a similar and predictable fashion, (b) whether there is gradual variation in phenotypic divergence reflecting variation in the strength of natural selection among populations, (c) whether the extent of this divergence is correlated between multiple character suites (i.e., concerted evolution), and (d) whether gradual variation in phenotypic divergence predicts the degree of...

Data from: Selective logging in tropical forests decreases the robustness of liana-tree interaction networks to the loss of host tree species

Ainhoa Magrach, Rebecca A. Senior, Andrew Rogers, Deddy Nurdin, Suzan Benedick, William F. Laurance, Luis Santamaría & David P. Edwards
Selective logging is one of the major drivers of tropical forest degradation, causing important shifts in species composition. Whether such changes modify interactions between species and the networks in which they are embedded remain fundamental questions to assess the ‘health’ and ecosystem functionality of logged forests. We focus on interactions between lianas and their tree hosts within primary and selectively logged forests in the biodiversity hotspot of Malaysian Borneo. We found that lianas were more...
