New Magnetic Field Models of the Moon

Dhananjay Ravat, Michael Purucker & Nils Olsen
We use L1-norm model regularization of |Br| component at the surface on magnetic monopoles bases and along-track magnetic field differences alone (without vector observations) to derive high quality global magnetic field models at the surface of the Moon. The practical advantages to this strategy are: monopoles are more stable at closer spacing in comparison to dipoles, improving spatial resolution; L1-norm model regularization leads to sparse models which may be appropriate for the Moon which has...

Suitability of Native Milkweed (Asclepias) Species versus Cultivars for Supporting Monarch Butterflies and Bees in Urban Gardens

Daniel A. Potter
Public interest in ecological landscaping and gardening is fueling a robust market for native plants. Most plants available to consumers through the horticulture trade are cultivated forms that have been selected for modified flowers or foliage, compactness, or other ornamental characteristics. Depending on their traits, some native plant cultivars seem to support pollinators, specialist insect folivores, and insect-based vertebrate food webs as effectively as native plant species, whereas others do not. There is particular need...

Ancestral state reconstruction for regeneration and autotomy in arthopods and reptiles

Jeremy Van Cleve, Luc Dunoyer & Ashley Seifert
Some form of regeneration occurs in all lifeforms and extends from single-cell organisms to humans. The degree to which regenerative ability is distributed across different taxa, however, is harder to ascertain given the potential for phylogenetic constraint or inertia, and adaptive processes to shape this pattern. Here, we examine the phylogenetic history of regeneration in two groups where the trait has been well-studied: arthropods and reptiles. Because autotomy is often present alongside regeneration in these...

Toxin or medication? Immunotherapeutic effects of nicotine on a specialist caterpillar

Michael Garvey, Justin Bredlau, Karen Kester, Curtis Creighton & Ian Kaplan
1. A core tenant in the field of ecological immunology is that immune responses trade off with other physiological functions due to resource-allocation costs. Caterpillars, for example, tend to exhibit reduced immune responses when reared on more toxic food plants due to a cost from detoxifying or sequestering secondary metabolites, also known as the “vulnerable host hypothesis”. However, support for this hypothesis is mixed, and studies have not yet mechanistically isolated the relative contributions of...

Data from: Nutrient availability controls the impact of mammalian herbivores on soil carbon and nitrogen pools in grasslands

Judith Sitters, E.R. Jasper Wubs, Elisabeth S. Bakker, Thomas W. Crowther, Peter B. Adler, Sumanta Bagchi, Jonathan D. Bakker, Lori Biederman, Elizabeth T. Borer, Elsa E. Cleland, Nico Eisenhauer, Jennifer Firn, Laureano Gherardi, Nicole Hagenah, Yann Hautier, Sarah E. Hobbie, Johannes M.H. Knops, Andrew S. MacDougall, Rebecca L. McCulley, Joslin L. Moore, Brent Mortensen, Pablo L. Peri, Suzanne M. Prober, Charlotte Riggs, Anita C. Risch … &
Grasslands have been subject to considerable alteration due to human activities globally, including widespread changes in populations and composition of large mammalian herbivores and elevated supply of nutrients. Grassland soils remain important reservoirs of carbon (C) and nitrogen (N). Herbivores may affect both C and N pools and these changes likely interact with increases in soil nutrient availability. Given the scale of grassland soil fluxes, such changes can have striking consequences for atmospheric C concentrations...

Does breeding season variation affect evolution of a sexual signaling trait in a tropical lizard clade?

Levi Gray, Anthony Barley, David Hillis, Carlos Pavón-Vázquez, Steven Poe & Brittney White
Sexually selected traits can be expected to increase in importance when the period of sexual behavior is constrained, such as in seasonally restricted breeders. Anolis lizard male dewlaps are classic examples of multifaceted signaling traits, with demonstrated intraspecific reproductive function reflected in courtship behavior. Fitch and Hillis found a correlation between dewlap size and seasonality in mainland Anolis using traditional statistical methods. Here, we present two tests of the Fitch-Hillis Hypothesis using new phylogenetic and...

Temperature-mediated plasticity in incubation schedules is unlikely to evolve to buffer embryos from climatic challenges in a seasonal songbird

Alexandra Cones, Andrea Liebl, Thomas Houslay & Andrew Russell
Phenotypic plasticity is hypothesised to facilitate adaptive responses to challenging conditions, such as those resulting from climate change. However, the key predictions of this ‘rescue hypothesis’, that variation in plasticity exists and can evolve to buffer unfavourable conditions, remain rare. Here, we investigate among-female variation in temperature-mediated plasticity of incubation schedules and consequences for egg temperatures using the chestnut-crowned babbler (Pomatostomus ruficeps) from temperate regions of inland south-eastern Australia. Given phenological advances in this seasonal...

Data from: Cryptic patterns of speciation in cryptic primates: microendemic mouse lemurs and the multispecies coalescent

Jelmer Poelstra, Jordi Salmona, George Tiley, Dominik Schüßler, Marina Blanco, Jean Andriambeloson, Olivier Bouchez, C. Ryan Campbell, Paul Etter, Amaia Iribar-Pelozuelo, Paul Hohenlohe, Kelsie Hunnicutt, Eric Johnson, Peter Kappeler, Peter Larsen, Sophie Manzi, Jose Ralison, Blanchard Randrianambinina, Rodin Rasoloarison, David Rasolofoson, Amanda Stahlke, David Weisrock, Rachel Williams, Lounes Chikhi, Ed Louis … & Anne Yoder
Species delimitation is ever more critical for assessing biodiversity in threatened regions of the world, especially when undescribed lineages may be at risk from habitat loss. Mouse lemurs (Microcebus) are an example of a rapid radiation of morphologically cryptic species that are distributed throughout Madagascar in its rapidly vanishing forested habitats. Here, we focus on two pairs of sister lineages that occur in a region in northeastern Madagascar that shows high levels of microendemism. We...

Plant-animal interactions between carnivorous plants, sheet-web spiders, and ground-running spiders as guild predators in a wet meadow community

James Krupa, Kevin Hopper, Samuel Gruber, Jason Schmidt & James Harwood
Plant-animal interactions are diverse and wide-spread shaping ecology, evolution and biodiversity of most ecological communities. Carnivorous plants are unusual in that they can be simultaneously engaged with animals in multiple mutualistic and antagonistic interactions including reversed plant-animal interactions where they are the predator. Competition with animals is a potential antagonistic plant-animal interaction unique to carnivorous plants when they and animal predators consume the same prey. The goal of this field study was to test the...

Data from: Shifts in species interactions and farming contexts mediate net effects of birds in agroecosystems

Elissa Olimpi, Karina Garcia, Daniel Karp & David Gonthier
Some birds are viewed as pests and vectors of foodborne pathogens in farmlands, yet birds also benefit growers by consuming pests. While many growers seek to prevent birds from accessing their farms, few studies have attempted to quantify the net effects of bird services and disservices, let alone how net effects shift across farm management strategies. We quantified the net effect of birds on crop production across 20 California strawberry (Fragaria x ananassa) farms that...

Speciation and gene flow in two sympatric small mammals from Madagascar, Microgale fotsifotsy and M. soricoides (Mammalia: Tenrecidae)

Kathryn M Everson, Link E Olson & Steven M Goodman
Madagascar’s shrew tenrecs (Mammalia: Tenrecidae: Microgale, Nesogale) form an excellent system for studying speciation. Most species are endemic to the island’s eastern moist evergreen forest, a region renowned for high levels of biodiversity and a high rate of in situ diversification. We set out to understand the speciation dynamics in a clade of recently described taxa: Microgale fotsifotsy and M. soricoides, which have nearly identical distributions in the moist evergreen forest, and M. nasoloi, which...

Comparison of native and non-native predator consumption rates and prey avoidance behavior in North America and Europe

Ayse Gül Ünlü, John J. Obrycki & Roman Bucher
Novel predator-prey interactions can contribute to the invasion success of non-native predators. For example, native prey can fail to recognize and avoid non-native predators due to a lack of co-evolutionary history and cue dissimilarity with native predators. This might result in a competitive advantage for non-native predators. Numerous lady beetle species were globally redistributed as biological control agents against aphids, resulting in novel predator-prey interactions. Here, we investigated the strength of avoidance behavior of the...

Collision between biological process and statistical analysis revealed by mean-centering

David Westneat, Yimen Araya-Ajoy, Hassen Allegue, Barbara Class, Niels Dingemanse, Ned Dochtermann, Laszlo Garamszegi, Julien Martin, Shinichi Nakagawa, Denis Reale & Holger Schielzeth
1. Animal ecologists often collect hierarchically-structured data and analyze these with linear mixed-effects models. Specific complications arise when the effect sizes of covariates vary on multiple levels (e.g., within vs among subjects). Mean-centering of covariates within subjects offers a useful approach in such situations, but is not without problems. 2. A statistical model represents a hypothesis about the underlying biological process. Mean-centering within clusters assumes that the lower level responses (e.g. within subjects) depend on...

Impact of Buckwheat and Methyl Salicylate Lures on Natural Enemy Abundance for Early Season Management of Melanaphis sacchari (Hemiptera: Aphididae) in Sweet Sorghum

Nathan Mercer
Tested effect of buckwheat flowers and methyl salicylate lures to attract natural enemies to sweet sorghum fields to manage Melanaphis sacchari, a recent pest of sweet sorghum.

Data from: A method to generate multi-locus barcodes of pinned insect specimens using MiSeq

Trace Akankunda, Hien To, Carlos R Lopez, Remko Leijs & Katja Hogendoorn
For molecular insect identification, amplicon sequencing methods are recommended because they offer a cost effective approach for targeting small sets of informative genes from multiple samples. In this context, high-throughput multilocus amplicon sequencing has been achieved using the MiSeq Illumina sequencing platform. However, this approach generates short gene fragments of less than 500 bp, which then have to be overlapped using bioinformatics to achieve longer sequence lengths. This increases the risk of generating chimeric sequences...

Spectral composition of light pollution affects melatonin suppression and West Nile virus infection resistance and mortality in the House Sparrow (Passer domesticus).

Meredith Kernbach, Vincent Cassone, Thomas Unnasch & Lynn Martin
Artificial light at night (ALAN) has become a pervasive anthropogenic stressor for both humans and wildlife. Although many negative impacts of ALAN on human health have been identified, the consequences for infectious disease dynamics are largely unexplored. With the increase in popularity of energy efficient light-emitting diodes (LEDs), the effects of spectral composition of ALAN have also come into question. Previous studies showed that exposure to low levels of incandescent ALAN extended the infectious period...

Phylogenetic relatedness mediates persistence and density of soil seed banks

Margherita Gioria, Petr Pyšek, Carol Baskin & Angelino Carta
Soil seed banks can strongly affect survival and expansion of plant populations by spreading mortality risks and distributing genetic diversity through time. Knowledge of the main factors regulating the ability of seeds to persist in the soil beyond the first growing season is however limited. While morphological and physiological seed traits, and the degree of environmental uncertainty are considered important in shaping the seed-banking strategies of plants, global assessments that explicitly account for phylogenetic relatedness...

Data from: Distinct cold tolerance traits independently vary across genotypes in Drosophila melanogaster

Mark Joseph Garcia, Aerianna S. Littler, Aditya Sriram & Nicholas Teets
The ability to cope with low temperature is a critical adaptation in thermally variable environments. Cold hardiness is comprised of several traits, including minimum temperatures for growth and activity, ability to survive severe cold, and ability to recover normal function after cold subsides. Across species, these traits are correlated and share physiological mechanisms, suggesting they were shaped by shared evolutionary processes. However, the extent cold hardiness traits and their associated mechanisms covary within populations has...
