Anthropogenic noise alters parental behavior and nestling development, but not fledging condition

Meelyn Mayank Pandit, James Eapen, Gabriela Pineda-Sabilon, Margaret Caulfield, Alexander Moreno, Jay Wilhelm, Jessica Ruyle, Eli Bridge & Darren Proppe
Anthropogenic noise is a ubiquitous feature of the American landscape, and is a known stressor for many bird species, leading to negative effects in behavior, physiology, reproduction, and ultimately fitness. While a number of studies have examined how anthropogenic noise affects avian fitness, there are few that simultaneously examine how anthropogenic noise impacts the relationship between parental care behavior and nestling fitness. We conducted Brownian noise playbacks for six hours a day during the nesting...

Supplementary material for: Phylogenomics and historical biogeography of seahorses, dragonets, goatfishes, and allies (Teleostei: Syngnatharia): Assessing factors driving uncertainty in biogeographic inferences

Ricardo Betancur-R
The charismatic trumpetfishes, goatfishes, dragonets, flying gurnards, seahorses, and pipefishes encompass a recently defined yet extraordinarily diverse clade of percomorph fishes—the series Syngnatharia. This group is widely distributed in tropical and warm-temperate regions, with a great proportion of its extant diversity occurring in the Indo-Pacific. Because most syngnatharians feature long-range dispersal capabilities, tracing their biogeographic origins is challenging. Here, we applied an integrative phylogenomic approach to elucidate the evolutionary biogeography of syngnatharians. We built upon...

Rice genome-scale network integration reveals transcriptional regulators of grass cell wall synthesis

Laura Bartley & Kangmei Zhao
Grasses have evolved distinct cell wall composition and patterning relative to dicotyledonous plants. However, despite the importance of this plant family, transcriptional regulation of its cell wall biosynthesis is poorly understood. To identify grass cell wall-associated transcription factors, we constructed the Rice Combined mutual Ranked Network (RCRN). The RCRN covers >90% of annotated rice (Oryza sativa) genes, is high quality, and includes most grass-specific cell wall genes, such as mixed-linkage glucan synthases and hydroxycinnamoyl acyltransferases....

Double-tagging scores of seabirds reveals that light-level geolocator accuracy is limited by species idiosyncrasies and equatorial solar profiles

Luke Halpin, Jeremy Ross, Raül Ramos, Rowan Mott, Nicholas Carlile, Nick Golding, José Manuel Reyes-González, Teresa Militão, Fernanda De Felipe, Zuzana Zajková, Marta Cruz Flores, Sarah Saldanha, Virginia Morera-Pujol, Leia Navarro-Herrero, Laura Zango, Jacob Gonzalez-Solis & Rohan Clarke
Light-level geolocators are popular bio-logging tools, with advantageous sizes, longevity, and affordability. Biologists tracking seabirds often presume geolocator spatial accuracies between 186-202 km from previously-innovative, yet taxonomically, spatially, and computationally limited, studies. Using recently developed methods, we investigated whether assumed uncertainty norms held across a larger-scale, multispecies study. We field-tested geolocator spatial accuracy by synchronously deploying these with GPS loggers on scores of seabirds across five species and 11 Mediterranean Sea, East Atlantic and South...

Specialized spatial cognition is associated with reduced cognitive senescence in a food-caching bird

Virginia Heinen, Angela Pitera, Ben Sonnenberg, Lauren Benedict, Carrie Branch, Eli Bridge & Vladimir Pravosudov
Senescence, the gradual reduction and loss of function as organisms age, is a widespread process that is especially pronounced in cognitive abilities. Senescence appears to have a genetic basis and can be affected by evolutionary processes. If cognitive senescence is shaped by natural selection, it may be linked with selection on cognitive abilities needed for survival and reproduction, such that species in which fitness is directly related to cognitive abilities should evolve delayed cognitive senescence....

Testing the utility of alternative metrics of branch support to address the ancient evolutionary radiation of tunas, stromateoids, and allies (Teleostei: Pelagiaria)

Dahiana Arcila, Lily C. Hughes, Fernando Meléndez-Vazquez, Carole C. Baldwin, William T. White, Kent E. Carpenter, Jeffrey T. Williams, Mudjekeewis D. Santos, John J. Pogonoski, Masaki Miya, Guillermo Ortí & Ricardo Betancur-R.
The use of high-throughput sequencing technologies to produce genome-scale datasets was expected to settle some long-standing controversies across the Tree of Life, particularly in areas where short branches occur at deep timescales. Instead, these datasets have often yielded many well-supported but conflicting topologies, and highly variable gene-tree distributions. A variety of branch-support metrics beyond the nonparametric bootstrap are now available to assess how robust a phylogenetic hypothesis may be, as well as new methods to...

Food discovery is associated with different reliance on social learning and lower cognitive flexibility across environments in a food caching bird

Virginia Heinen, Angela Pitera, Ben Sonnenberg, Lauren Benedict, Eli Bridge, Damien Farine & Vladimir Pravosudov
Social learning is a primary mechanism for information acquisition in social species. Despite many benefits, social learning may be disadvantageous when independent learning is more efficient. For example, searching independently may be more advantageous when food sources are ephemeral and unpredictable. Individual differences in cognitive abilities such as spatial memory, which affect an individual’s environmental predictability, can also be expected to influence social information use. We investigated how resident food-caching chickadees discovered multiple novel food...

Population genetics, demographic and evolutionary history of the Dudley’s lousewort, a rare redwood forest specialist (Pedicularis dudleyi)

Tracy Misiewicz
Pedicularis dudleyi (Dudley’s Lousewort, Orobanchaceae) is an extremely rare wildflower endemic to the redwood forests of Central California. Until recently the species was known only from three extant natural populations. However, one of those populations was recently described as a novel species (P. rigginsiae D.J. Keil) based on morphological and ecological data leaving only two populations described as P. dudleyi. While little is known about the past distribution of the species, historical records have led...

Energy pathways modulate the resilience of stream invertebrate communities to drought

Daniel Nelson, Michelle Busch, Darin Kopp & Daniel Allen
1. While climate change is altering ecosystems on a global scale, not all ecosystems are responding in the same way. The resilience of ecological communities may depend on whether food webs are producer- or detritus-based (i.e. “green” or “brown” food webs, respectively), or both (i.e. “multi-channel” food web). 2. Food web theory suggests that the presence of multiple energy pathways can enhance community stability and resilience and may modulate the responses of ecological communities to...

Deep reefs are not refugium for shallow-water fish communities in the southwestern Atlantic

Aline Medeiros, Beatrice Ferreira, Fredy Alvarado, Ricardo Betancur-R, Marcelo Soares & Bráulio Santos
1. The deep reef refugia hypothesis (DRRH) predicts that deep reef ecosystems may act as refugium for the biota of disturbed shallow waters. Because deep reefs are amongst the most understudied habitats on Earth, formal tests of the DRRH remain scarce. If the DRRH is valid at the community level, the diversity of species, functions and lineages of fish communities of shallow reefs should be encapsulated in deep reefs. 2. We tested the DRRH by...

Life history and environment predict variation in testosterone across vertebrates

Jerry Husak, Matthew Fuxjager, Michele A. Johnson, Maren Vitousek, Jeremy Donald, Clinton David Francis, Wolfgang Goymann, Michaela Hau, Bonnie Kircher, Rosemary Knapp, Lynn B. Martin, Eliot Miller, Laura Schoenle & Tony Williams
Endocrine systems act as key intermediaries between organisms and their environments. This interaction leads to high variability in hormone levels, but we know little about the ecological factors that influence this variation within and across major vertebrate groups. We study this topic by assessing how various social and environmental dynamics influence testosterone levels across the entire vertebrate tree of life. Our analyses show that breeding season length and mating system are the strongest predictors of...

Male secondary sexual traits do not predict female preference in Caribbean livebearing fishes (Limia)

Montrai Spikes
Female preference is widely described in various taxa, and the underlying mechanisms shaping preferences remain a major focus of sexual selection studies, particularly in species where males contribute minimally to offspring. Female preference is associated with maintaining male secondary sexual traits (SST). However, how male SST impact female preference is less understood. We hypothesized the strength of female preference should scale with the expression of male SST. To test this prediction, we compared female preference...

Data to accompany: Rapid body color change provides lizards with facultative crypsis in the eyes of their avian predators

Kelly Wuthrich, Amber Nagel & Lindsey Swierk
Color change serves many antipredator functions and may allow animals to better match environments or disrupt outlines to prevent detection. Rapid color change could potentially provide camouflage to animals that frequently move among microhabitats. Determining the adaptiveness of whole-animal rapid color changes in natural habitats with respect to predator visual systems would greatly broaden our fundamental understanding of the evolution of rapid color change. We tested whether whole-body color change provides water anoles (Anolis aquaticus)...

The dissimilatory sulfate-reducing Deltaproteobacterium, Desulfovibrio vulgaris Hildenborough (ATCC 29579), was chosen by the LBNL-led research collaboration ENIGMA to explore tools and protocols for bringing this anaerobe to model status. Here we describe a collection of genetic constructs generated by ENIGMA, which are available to the research community.

Summary table and references of studies of the biogeography of the West Indies found in the Web of Science Core Collection database

Rodet Rodriguez Silva & Ingo Schlupp
Studies of the biogeography of the West Indies are numerous but not all taxonomic groups have received the same attention. Many of the contributions to this field have historically focused on terrestrial vertebrates from a perspective closely linked to the classical theory of island biogeography. However, some recent works have questioned whether some of the assumptions of this theory are too simplistic. In this review, we compiled information about the West Indies biogeography based on...

Grasshoppers, other arthropods, plant, and soil data from Konza Prairie bison grazing lawns

Katerina Ozment, Ellen Welti, Monica Shaffer & Michael Kaspari
1. We contrast the response of arthropod abundance and composition to bison grazing lawns during a drought and non-drought year, with an emphasis on acridid grasshoppers, an important grassland herbivore. 2. Grazing lawns are grassland areas where regular grazing by mammalian herbivores creates patches of short-statured, high nutrient vegetation. Grazing lawns are predictable microsites that modify microclimate, plant structure, community composition, and nutrient availability, with likely repercussions for arthropod communities. 3. One year of our...

What does it mean to be wild? Assessing human influence on the environments of nonhuman primate specimens in museum collections

Andrea Eller, Stephanie Canington, Sana Saiyed, Rita Austin, Courtney Hofman & Sabrina Sholts
Natural history collections are often thought to represent environments in a pristine natural state, free from human intervention – the so-called “wild”. In this study, we aim to assess the level of human influence represented by natural history collections of wild-collected primates over 120 years at the Smithsonian Institution’s National Museum of Natural History (NMNH). Our sample consisted of 875 catarrhine primate specimens in NMNH collections, representing 13 genera collected in 39 countries from 1882...

Trophic differences regulate grassland food webs: herbivores track food quality and predators select for habitat volume

Rebecca Prather, Ellen Welti & Michael Kaspari
The impacts of altered biogeochemical cycles on ecological systems are likely to vary with trophic level. Predicting how these changes will affect ecological food webs is further complicated by human activities which are simultaneously altering the availability of macronutrients like nitrogen (N) and phosphorus (P), and micronutrients such as sodium (Na). Here we contrast three hypotheses that predict how increasing nutrient availability will shape grassland food webs. We conducted a distributed factorial fertilization experiment (N...

Convergent craniofacial evolution and biogeography of weakly electric Mormyridae and Bonytongue Fishes (Osteoglossomorpha)

Rose Peterson, John Sullivan, Carl Hopkins, Aintzane Santaquiteria, Casey Dillman, Stacy Pirro, Ricardo Betancur, Dahiana Arcila, Lily C. Hughes & Guillermo Ortí
Bonytongues (Osteoglossomorpha) constitute an ancient clade of teleost fishes distributed in freshwater habitats throughout the world. The group includes well-known species such as arowanas, featherbacks, pirarucus, and the weakly electric fishes in the family Mormyridae. Their disjunct distribution, extreme morphologies, and electrosensory capabilities (Notopteridae and Mormyroidea) have attracted interest by many, yet a comprehensive phylogenetic framework for comparative analysis is missing. We provide a phylogenomic analysis of 179 species (out of 260), 28 out of...

Social dominance status is associated with differences in spatial cognitive flexibility in wild mountain chickadees

Virginia Heinen, Lauren Benedict, Angela Pitera, Benjamin Sonnenberg, Eli Bridge & Vladimir Pravosudov
Social dominance has long been used as a model to investigate social stress. However, many studies using such comparisons have been performed in captive environments. These environments may produce unnaturally high antagonistic interactions, exaggerating the stress of social subordination and any associated adverse consequences. One such adverse effect concerns impaired cognitive ability, often thought to be associated with social subordination. Here, we tested whether social dominance rank is associated with differences in spatial learning and...

Tests of search image and learning in the wild: insights from sexual conflict in damselflies

Silvana Piersanti, Gianandrea Salerno, Manuela Rebora, Albyn Jones, Leonardo Giontella, Vivana Di Pietro & Ola Fincke
Search image formation, a proximal mechanism to maintain genetic polymorphisms by negative frequency-dependent selection, has rarely been tested under natural conditions. Females of many non-territorial damselflies resemble either conspecific males or background vegetation. Mate-searching males are assumed to form search images of the majority female type, sexually harassing it at rates higher than expected from its frequency, thus selectively favoring the less common morph. We tested this and how morph coloration and behavior influenced male...

Interspecific introgression reveals a role of male genital morphology during the evolution of reproductive isolation in Drosophila

Stephen R. Frazee, Angelica R. Harper, Mehrnaz Afkhami, Michelle L. Wood, John C. McCrory & John P. Masly
Rapid divergence in genital structures among nascent species has been posited to be an early-evolving cause of reproductive isolation, although evidence supporting this idea as a widespread phenomenon remains mixed. Using a collection of interspecific introgression lines between two Drosophila species that diverged ~240,000 years ago, we tested the hypothesis that even modest divergence in genital morphology can result in substantial fitness losses. We studied the reproductive consequences of variation in the male epandrial posterior...

Current status and future strategies for mentoring women in neurology

Christa San Luis Nobleza, Amtul Farheen, Ilena George, Divya Singhal, Regina Troxell, Jyoti Pillai, Logan Schneider, Catherine Lomen-Hoerth, Jennifer Graves & Stefano Sandrone
The American Academy of Neurology's (AAN) 2017 Gender Disparity Report identified improving mentorship as a key intervention to fill the leadership and pay gaps for women in neurology. Here we summarize the literature on mentoring women, provide an outline of ideal components of programs geared toward closing gender gaps, and present a mentoring program for AAN members. The strategies discussed share similarities with those for closing gaps related to race, ethnicity and religion. Developing effective...
