Emma L Carroll, Paulo Ott, Louise McMillan, Bárbara Galletti Vernazzani, Petra Neveceralova, Els Vermeulen, Oscar Gaggiotti, Artur Andriolo, C. Scott Baker, Connor Bamford, Peter Best, Elsa Cabrera, Susannah Calderan, Andrea Chirife, Rachel M. Fewster, Paulo A. C. Flores, Timothy Frasier, Thales R. O. Freitas, Karina Groch, Pavel Hulva, Amy Kennedy, Russell Leaper, Mathew S. Leslie, Michael Moore, Larissa Oliviera … & Jennifer A Jackson
As species recover from exploitation, continued assessments of connectivity and population structure are warranted to provide information for conservation and management. This is particularly true in species with high dispersal capacity, such as migratory whales, where patterns of connectivity could change rapidly. Here we build on a previous long-term, large-scale collaboration on southern right whales (Eubalaena australis) to combine new (nnew) and published (npub) mitochondrial (mtDNA) and microsatellite genetic data from all major wintering grounds...

Data from: Temporal stability versus community matrix measures of stability and the role of weak interactions

Amy Downing, Craig Jackson, Claire Plunkett, Jayne Lockhart & Shannon Schlater
Relationships between different measures of stability are not well understood in part because empiricists and theoreticians tend to measure different aspects and most studies only explore a single form of stability. Using time-series data from experimental plankton communities, we compared temporal stability typically measured by empiricists (coefficient of variation of biomass) to stability measures typically measured by theoreticians derived from the community matrix (asymptotic resilience, initial resilience, and intrinsic stochastic invariability) using first-order multivariate autoregressive...

Dataset of Constraining fossil fuel CO2 emissions from urban area using OCO-2 observations of total column CO2

X. Ye, T. Lauvaux, E.A. Kort, T. Oda, S. Feng, J.C. Lin, E.G. Yang & D. Wu
Satellite observations of the total column dry-air CO2 (XCO2) are expected to support the quantification and monitoring of fossil fuel CO2 (ffCO2) emissions from urban areas. We evaluate the utility of the Orbiting Carbon Observatory 2 (OCO-2) XCO2 retrievals to optimize whole-city emissions, using a Bayesian inversion system and high-resolution transport modeling. The uncertainties of constrained emissions related to transport model, satellite measurements, and local biospheric fluxes are quantified. For the first two uncertainty sources,...

Dense seismic three-component nodal array at the Ramona Reservation

, , &
High-Resolution imaging and monitoring of the subsurface structure and seismicity at a site along the San Jacinto fault zone using a dense seismic nodal array. The site is located about 6 km northwest of the town of Anza, California. The type of nodal sensor employed is the Fairfield Zland 3-component 5 Hz geophones (records ground velocity continuously at 500 sps). The array consists of 97 sensors, with 65 located along a linear across-fault profile and...

Data from: The arboreal ants of a Neotropical rainforest show high species density and comprise one third of the ant fauna

John Longino & Robert Colwell
In tropical rainforests, the ant community can be divided into ground and arboreal faunas. Here we report a thorough sampling of the arboreal ant fauna of La Selva Biological Station, a Neotropical rainforest site. Forty-five canopy fogging samples were centered around large trees. Individual samples harbored an average of 35 ant species, with up to 55 species in a single sample. The fogging samples yielded 163 observed species total, out of a statistically estimated 199...

The limits of convergence: the roles of phylogeny and dietary ecology in shaping non-avian amniote skulls

Keegan Melstrom, Kenneth Angielczyk, Kathleen Ritterbush & Randall Irmis
Cranial morphology is remarkably varied in living amniotes, ranging from short-faced mammals to the elongate snouts of crocodylians. This diversity of shapes is thought to correspond with feeding ecology, a relationship repeatedly demonstrated at smaller phylogenetic scales, but one that remains untested across amniote phylogeny. Using a combination of 2D geometric and linear morphometrics, we investigate the links between phylogenetic relationships, diet, and skull shape in an expansive dataset of extant amniotes with teeth: mammals,...

Individual differences determine the strength of ecological interactions

Jason I. Griffiths, Dylan Z. Childs, Ronald D. Bassar, Tim Coulson, David N Reznick & Mark Rees
Biotic interactions are central to both ecological and evolutionary dynamics. In the vast majority of empirical studies, the strength of intraspecific interactions is estimated by using simple mea- sures of population size. Biologists have long known that these are crude metrics, with experiments and theory suggesting that interactions between individuals should depend on traits, such as body size. Despite this, it has been difficult to estimate the impact of traits on competitive ability from ecological...

Data from: Vascular epiphytes show low physiological resistance and high recovery capacity to episodic, short-term drought in Monteverde, Costa Rica

Cameron Williams, Jessica Murray, Andrew Glunk, Todd Dawson, Nalini Nadkarni & Sybil Gotsch
Tropical montane cloud forests support abundant epiphytic vascular plant communities that serve important ecosystem functions, but their reliance on atmospheric inputs of water may make them susceptible to the drying effects of rising cloud bases and more frequent droughts. We conducted a common garden experiment to explore the combined effects of decreasing cloud influence—lower humidity, warmer temperature, brighter light—and meteorological drought (i.e., absence of rain) on the physiology and morphology of vascular epiphytes native to...

Anatomy, ontogeny, and evolution of the archosaurian respiratory system: a case study on Alligator mississippiensis and Struthio camelus

Emma Schachner, Brandon Hedrick, Heather Richbourg, John Hutchinson & CG Farmer
The avian lung is highly specialized and is both functionally and morphologically distinct from that of their closest extant relatives, the crocodilians. It is highly partitioned, with a unidirectionally ventilated and immobilized gas-exchanging lung, and fully decoupled, compliant, poorly vascularized ventilatory air-sacs. To understand the evolutionary history of the archosaurian (birds, crocodilians and their common ancestors) respiratory system, it is essential to determine which anatomical characteristics are shared between birds and crocodilians and the role...

Data from: The role of scratching in the control of ectoparasites on birds

Graham B. Goodman, Margaux C. Klingensmith, Sarah E. Bush & Dale H. Clayton
Grooming by birds is thought to serve essential anti-parasite functions. While preening has been well studied, little is known about the function of scratching in birds. We conducted a series of experiments to determine the effectiveness of scratching for controlling feather lice (Columbicola columbae) on rock pigeons (Columba livia). First, we used a hobbling technique to impair scratching. After six months, hobbled birds had significantly more lice than controls that could scratch. In addition, lice...

Data from: Impact protection potential of mammalian hair

David Carrier, Ethan Beseris & Steven Naleway
Because facial hair is one of the most sexually dimorphic features of humans (Homo sapiens) and is often perceived as an indicator of masculinity and social dominance, human facial hair has been suggested to play a role in male contest competition. Some authors have proposed that the beard may function similar to the long hair of a lion’s mane, serving to protect vital areas like the throat and jaw from lethal attacks. This is consistent...

Phylogenomic species delimitation, taxonomy, and \"bird guide\" identification for the Neotropical ant genus Rasopone (Hymenoptera: Formicidae)

John Longino & Michael Branstetter
Rasopone Schmidt & Shattuck is a poorly known lineage of ants that live in Neotropical forests. Informed by phylogenetic results from thousands of ultraconserved elements (UCEs) and mitochondrial DNA barcodes, we revise the genus, providing a new morphological diagnosis and a species-level treatment. Analysis of UCE data from many Rasopone samples and select outgroups revealed non-monophyly of the genus. Monophyly of Rasopone was restored by transferring several species to the unrelated genus Mayaponera Schmidt &...

Photochemical Reflectance Index (PRI) captures the ecohydrological sensitivity of a semi-arid mixed conifer forest

Julia Yang, Greg Barron-Gafford, William Smith, Dong Yan, Russell Scott & John Knowles
The Photochemical Reflectance Index (PRI) corresponds to the de-epoxidation state of the xanthophyll cycle and is one of the few pigment-based vegetation indices sensitive to rapid plant physiological responses. As such, new remotely-sensed PRI products present opportunities to study diurnal and seasonal processes in evergreen conifer forests, where complex vegetation dynamics are not well reflected by the small annual changes in chlorophyll content or leaf structure. Because PRI is tied explicitly to short and long...

Musculoskeletal mass and shape are correlated with competitive ability in male house mice (Mus musculus)

Amanda Cooper, Christopher Cunningham, Jeremy Morris, James Ruff, Wayne Potts & David Carrier
Intense physical competition between males for mating opportunities is widespread among mammals. In such agonistic encounters, males with combinations of morphological, physiological, and behavioral characters that allow them to dominate an opponent often have greater fitness. However, the specific physical traits associated with competitive ability are poorly understood. Larger body size is often correlated with fitness in mammals. Interestingly, fitness is maximized at intermediate body masses in male house mice (Mus musculus), a species with...

Integrating UCE phylogenomics with traditional taxonomy reveals a trove of New World Syscia species (Formicidae, Dorylinae)

Michael G. Branstetter & John T. Longino
The ant genus Syscia is part of the cryptic ant fauna inhabiting leaf litter and rotten wood in the Asian and American tropics. It is a distinct clade within the Dorylinae, the subfamily from which army ants arose. Prior to this work the genus comprised seven species, each known from a single or very few collections. Extensive collecting in Middle America revealed an unexpected and challenging diversity of morphological forms. Locally distinct forms could be...
