Data for: Social-ecological vulnerability of fishing communities to climate change: a U.S. West Coast case study

Laura Koehn, Laura Nelson, Jameal Samhouri, Karma Norman, Michael Jacox, Alison Cullen, Jerome Fiechter, Mercedes Pozo Buil & Phillip Levin
Climate change is already impacting coastal communities, and ongoing and future shifts in fisheries species productivity from climate change have implications for the livelihoods and cultures of coastal communities. Harvested marine species in the California Current Large Marine Ecosystem support U.S. West Coast communities economically, socially, and culturally. Ecological vulnerability assessments exist for individual species in the California Current but ecological and human vulnerability are linked and vulnerability is expected to vary by community. Here,...

De Omena, Gustavo Q. Romero, Fabiola Ospina Bautista, Nicholas A. C. Marino, Céline Leroy, Vinicius F. Farjalla, Barbara A. Richardson, Ana Z. Gonçalves, Bruno Corbara, Jana S. Petermann, Michael J. Richardson, Michael C. Melnychuk, Merlijn Jocqué, Jacqueline T. Ngai, Stanislas Talaga, Gustavo C. O. Piccoli … & Régis Céréghino
It has been argued that the mechanisms structuring ecological communities may be more generalizable when based on traits than on species identities. If so, patterns in the assembly of community-level traits along environmental gradients should be similar in different places in the world. Alternatively, geographic change in the species pool and regional variation in climate might result in site-specific relationships between community traits and local environments. These competing hypotheses are particularly untested for animal communities....

Site fidelity increases reproductive success by increasing foraging efficiency in a marine predator

Ginger Rebstock, Briana Abrahms & Dee Boersma
Seabirds must find food efficiently in the dynamic ocean environment to succeed at raising chicks. In theory, site familiarity, gained by prior experience in a place, should increase foraging efficiency when prey is predictable. For non-flying species like penguins, prior experience may be the only source of information on prey location. Penguins should therefore exhibit high foraging-site fidelity, particularly when prey is more predictable. Using movement data from 180 Magellanic penguins Spheniscus magellanicus tracked during...

Data from: Intrapopulation differences in polar bear movement and step selection patterns

Ryan Wilson, Michelle St Martin, Eric Regehr & Karyn Rode
Background: The spatial ecology of individuals often varies within a population or species. Identifying how individuals in different classes interact with their environment can lead to a better understanding of population responses to human activities and environmental change and improve population estimates. Most inferences about polar bear (Ursus maritimus) spatial ecology are based on data from adult females due to morphological constraints on applying satellite radio collars to other classes of bears. Recent studies, however,...

Functional architecture of neural circuits for leg proprioception in Drosophila

Chenghao Chen, Sweta Agrawal, Brandon Mark, Akira Mamiya, Anne Sustar, Jasper Phelps, Wei-Chung Lee, Barry Dickson, Gwyneth Card & John Tuthill
To effectively control their bodies, animals rely on feedback from proprioceptive mechanosensory neurons. In the Drosophila leg, different proprioceptor subtypes monitor joint position, movement direction, and vibration. Here, we investigate how these diverse sensory signals are integrated by central proprioceptive circuits. We find that signals for leg joint position and directional movement converge in second-order neurons, revealing pathways for local feedback control of leg posture. Distinct populations of second-order neurons integrate tibia vibration signals across...

Histological and life history data for small-bodied mammals from: Multituberculate mammals show evidence of a life history strategy similar to that of placentals, not marsupials

Lucas Weaver, Henry Fulghum, David Grossnickle, William Brightly, Zoe Kulik, Gregory Wilson Mantilla & Megan Whitney
The remarkable evolutionary success of placental mammals has been partly attributed to their reproductive strategy of prolonged gestation and birthing of relatively precocial, quickly weaned neonates. Although this strategy was conventionally considered derived relative to that of marsupials with highly altricial neonates and long lactation periods, mounting evidence has challenged this view. Until now, the fossil record has been relatively silent on this debate, but here we find that proportions of different bone tissue microstructures...

Dual spring force couples yield multifunctionality and ultrafast, precision rotation in tiny biomechanical systems

S. N. Patek, Ryan St. Pierre, Greg Sutton, Suzanne Cox, Sarah Bergbreiter, Adam Summers & Chi-Yun Kuo
Small organisms use propulsive springs rather than muscles to repeatedly actuate high acceleration movements, even when constrained to tiny displacements and limited by inertial forces. Through integration of a large kinematic dataset, measurements of elastic recoil, energetic math modeling, and dynamic math modeling, we tested how trap-jaw ants (Odontomachus brunneus) utilize multiple elastic structures to develop ultrafast and precise mandible rotations at small scales. We found that O. brunneus develops torque on each mandible using...

Data from: Glacial ice supports a distinct and undocumented polar bear subpopulation persisting in late 21st-century sea-ice conditions

Kristin Laidre, Megan Supple, Erik Born, Eric Regehr, Øystein Wiig, Fernando Ugarte, Jon Aars, Rune Dietz, Christian Sonne, Peter Hegelund, Carl Isaksen, Geir Akse, Benjamin Cohen, Harry Stern, Twila Moon, Christopher Vollmers, Russ Corbett-Detig, David Paetkau & Beth Shapiro
Polar bears are susceptible to climate warming because of their dependence on sea ice, which is declining rapidly. We present the first evidence for a genetically distinct and functionally isolated group of polar bears in Southeast Greenland. These bears occupy sea-ice conditions resembling those projected for the High Arctic in the late 21st century, with an annual ice-free period that is >100 days longer than the estimated fasting threshold for the species. Whereas polar bears...

Data from: IFN-γ-independent control of M. tuberculosis requires CD4 T cell-derived GM-CSF and activation of HIF-1α

Sarah Stanley & Erik Van Dis
RNA sequencing dataset from "Van Dis et al., IFN-γ-independent control of M. tuberculosis requires CD4 T cell-derived GM-CSF and activation of HIF-1α. 2022" The prevailing model of protective immunity to tuberculosis is that CD4 T cells produce the cytokine IFN-γ to activate bactericidal mechanisms in infected macrophages. Although IFN-γ-independent CD4 T cell based control of M. tuberculosis infection has been demonstrated in vivo it is unclear whether CD4 T cells are capable of directly activating...

Biodiversity and infrastructure interact to drive tourism to and within Costa Rica

Alejandra Echeverri, Jeffrey R. Smith, Dylan MacArthur-Waltz, Katherine S. Lauck, Christopher B. Anderson, Rafael Monge Vargas, Irene Alvarado Quesada, Spencer A. Wood, Rebecca Chaplin-Kramer & Gretchen C. Daily
Significance Tourism accounts for roughly 10% of global gross domestic product, with nature-based tourism its fastest-growing sector in the past 10 years. Nature-based tourism can theoretically contribute to local and sustainable development by creating attractive livelihoods that support biodiversity conservation, but whether tourists prefer to visit more biodiverse destinations is poorly understood. We examine this question in Costa Rica and find that more biodiverse places tend indeed to attract more tourists, especially where there is...

Ecological analysis of Pavlovian fear conditioning in rats

Peter Zambetti, Bryan Schuessler, Bryce Lecamp, Andrew Shin, Eun Joo Kim & Jeansok Kim
Pavlovian fear conditioning, which offers the advantage of simplicity in both the control of conditional and unconditional stimuli (CS, US) presentation and the analysis of specific conditional and unconditional responses (CR, UR) in a controlled laboratory setting, has been the standard model in basic and translational fear research. Despite 100 years of experiments, the utility of fear conditioning has not been trans-situationally validated in real-life contexts. We thus investigated whether fear conditioning readily occurs and...

Dataset from: Are we telling the same story? Comparing inferences made from camera trap and telemetry data for wildlife monitoring

Sarah Bassing, Melia DeVivo, Taylor Ganz, Brian Kertson, Laura Prugh, Trent Roussin, Lauren Satterfield, Rebecca Windell, Aaron Wirsing & Beth Gardner
Estimating habitat and spatial associations for wildlife is common across ecological studies, and it is well known that individual traits can drive population dynamics and vice versa. Thus, it is commonly assumed that individual- and population-level data should represent the same underlying processes, but few studies have directly compared contemporaneous data representing these different perspectives. We evaluated the circumstances under which data collected from Lagrangian (individual-level) and Eulerian (population-level) perspectives could yield comparable inferences in...

Washington harbor seal stable isotope data

Megan Feddern
Understanding the response of predators to ecological change at multiple temporal scales can elucidate critical predator-prey dynamics that would otherwise go unrecognized. We performed compound-specific nitrogen stable isotope analysis (CSIA) of amino acids on 153 harbor seal museum skull specimens to determine how trophic position of this marine predator has responded to ecosystem change over the past century. The relationships between harbor seal trophic position, ocean condition, and prey abundance, were analyzed using hierarchical modelling...

The functional diversity of marsupial limbs is influenced by both ecology and developmental constraint

Spencer Pevsner, David Grossnickle & Zhe-Xi Luo
Extant marsupials are less ecologically diverse than placentals, and this is reflected by placentals exhibiting a greater diversity of locomotor modes, including powered flight and fully aquatic swimming. One proposed explanation for this discrepancy is that the development of more disparate marsupial forelimbs is prevented by the neonate’s crawl to the pouch, which requires precocious forelimb development for climbing adaptations. To test predictions of this Developmental Constraint Hypothesis, we pursue a comparative morphometric study on...

Experimental data testing CO2 × heatwave effects in Pacific herring offspring including data on vital rates and experimental conditions

Christopher Murray
Forage fish tend to respond strongly to environmental variability and therefore may be particularly sensitive to marine climate stressors. We used controlled laboratory experiments to assess the vulnerability of Pacific herring (Clupea pallasii) embryos to the combined effects of high pCO2 and a simulated marine heatwave. The two pCO2 treatments reflected current conditions (~550 µatm) and a future extreme level (~2,300 µatm). The dynamics of heatwave (i.e., rate of onset: ~0.85°C d-1; maximum intensity: +4.4°C)...

Data for: Long duration advertisement calls of nesting male plainfin midshipman fish are honest indicators of size and condition

Sujay Balebail
The plainfin midshipman fish (Porichthys notatus) has long served as a model organism for neuroethology research on acoustic communication and related social behaviors. Type I or ‘singing’ males produce highly stereotyped, periodic advertisement calls that are the longest known uninterrupted vertebrate vocalizations. Despite the extensive literature on the acoustic behaviour of this species, it remains unclear whether reproductive males signal their quality via their highly energetic, multiharmonic advertisement calls. Here, we recorded the advertisement calls...

Mammalian resilience to megafire in western U.S. woodland savannas

Kendall Calhoun, Benjamin R. Goldstein, Kaitlyn M. Gaynor, Alex McInturff, Leonel Solorio & Justin Brashares
Increasingly frequent megafires, wildfires that exceed the size and severity of historical fires, are dramatically altering landscapes and critical habitats across the world. Across the western U.S., megafires have become an almost annual occurrence, but the implications of these fires for the conservation of native wildlife remain relatively unknown. Woodland savannas are among the world’s most biodiverse ecosystems and provide important food and structural resources to a variety of wildlife, but they are potentially threatened...

Pacific Parasites Data - Life history mediates the association between parasite abundance and geographic features

Maureen Williams
1. Though parasites are ubiquitous in marine ecosystems, predicting the abundance of parasites present within marine ecosystems has proven challenging due to the unknown effects of multiple interacting environmental gradients and stressors. Furthermore, parasites often are considered as a uniform group within ecosystems despite their significant diversity. 2. We aim to determine the potential importance of multiple predictors of parasite abundance in coral reef ecosystems, including reef area, island area, human population density, chlorophyll-a, host...

The symmetry spectrum in a hybridising, tropical group of rhododendrons

Valerie L. Soza, Ricardo Kriebel, Elizabeth Ramage, Benjamin Hall & Alex Twyford
Many diverse plant clades possess bilaterally symmetrical flowers and specialized pollination syndromes suggesting these traits may promote diversification. We examine the evolution of diverse floral morphologies and the association with diversification history in a species-rich tropical radiation of Rhododendron. We used restriction-site associated DNA sequencing on 114 taxa from Rhododendron sect. Schistanthe to reconstruct phylogenetic relationships, infer colonization of Southeast Asia and examine hybridization. We then captured and quantified floral variation using geometric morphometric analyses...
