Dolors Armenteras, Liliana María Davalos, Joan Sebastian Barreto, Angela Hernandez-Moreno, Carlos Zamorano-Elgueta, Tania Gonzalez-Delgado, Maria Constanza Meza, Alejandro Miranda & Javier Retana
Fire plays a dominant role in deforestation, particularly in the tropics, but the relative extent of transformations and influence of fire frequency on eventual forest loss remain unclear. Here we analyze the frequency of fire and its influence on post-fire forest trajectories between 2001-2018. We account for ~1.1% of Latin American forests burnt in 2002-2003 (8,465,850 ha). Although 40.1% of forests (3,393,250 ha) burned only once, by 2018~48% of the evergreen forests converted to other,...

The loss of the ‘pelvic step’ in human evolution

Nathan Thompson, Danielle Rubinstein, William Parrella-O'Donnell, Matthew Brett, Brigitte Demes, Susan Larson & Matthew O'Neill
Human bipedalism entails relatively short strides compared with facultatively bipedal primates. Unique non-sagittal-plane motions associated with bipedalism may account for part of this discrepancy. Pelvic rotation anteriorly translates the hip, contributing to bipedal stride length (i.e. the ‘pelvic step’). Facultative bipedalism in non-human primates entails much larger pelvic rotation than in humans, suggesting that a larger pelvic step may contribute to their relatively longer strides. We collected data on the pelvic step in bipedal chimpanzees...

Large‐scale genome sampling reveals unique immunity and metabolic adaptations in bats

Diana Daniela Moreno Santillan, Tanya Lama, Yocelyn T Gutierrez Guerrero, Zixia Huang, Graham Hughes, Alexis Brown, Paul Donat, Huabin Zhao, Stephen Rossiter, Laurel Yohe, Joshua Potter, Emma Teeling, Sonja Vernes, Kalina Davies, Eugene Myers, Federico Hoffmann, Angelique Corthals, David Ray & Liliana Davalos
Comprising more than 1,400 species, bats possess adaptations unique among mammals including powered flight, unexpected longevity given small body size, and extraordinary immunity. Some of the molecular mechanisms underlying these unique adaptations includes DNA repair, metabolism and immunity. However, analyses have been limited to a few divergent lineages, reducing the scope of inferences on gene family evolution across the Order Chiroptera. We conducted an exhaustive comparative genomic study of 37 bat species encompassing a large...

Across borders: external factors and prior behavior influence North Pacific albatross associations with fishing vessels

Rachael Orben, Josh Adams, Michelle Hester, Scott Shaffer, Robert Suryan, Tomohiro Deguchi, Kiyoaki Ozaki, Fumio Sato, Lindsay Young, Corey Clatterbuck, Melinda Conners, David Kroodsma & Leigh Torres
1. Understanding encounters between marine predators and fisheries across national borders and outside national jurisdictions offers new perspectives on unwanted interactions to inform ocean management and predator conservation. Although seabird-fisheries overlap has been documented at many scales, remote identification of vessel encounters has lagged because vessel movement data often is lacking. 2. Here, we reveal albatross-fisheries associations throughout the North Pacific Ocean. We identified commercial fishing operations using Global Fishing Watch data and algorithms to...

Raw data for: Biomechanical demands of percussive techniques in the context of early stone toolmaking

Robin Macchi, Guillaume Daver, Michel Brenet, Sandrine Prat, Laurent Hugueville, Sonia Harmand, Jason Lewis & Mathieu Domalain
Recent discoveries in archaeology and palaeoanthropology highlight that stone stool knapping could have emerged first within the genera Australopithecus or Kenyanthropus rather than Homo. To explore the implications of this hypothesis determining the physical demands and motor control needed for performing the percussive movements during the oldest stone toolmaking technology (i.e. Lomekwian) would help. We analysed the joint-angle patterns and muscle activity of a knapping expert using three stone tool replication techniques: unipolar flaking on...

Data from: Characterization of the abiotic drivers of abundance of nearshore Arctic fishes

Noah Khalsa, Kyle Gatt, Trent Sutton & Amanda Kelley
Fish are critical ecologically and socioeconomically for subsistence economies in the Arctic, an ecosystem undergoing unprecedented environmental change. Our understanding of the responses of nearshore Arctic fishes to environmental change is inadequate because of limited research on the physicochemical drivers of abundance occurring at a fine scale. Here, high-frequency in-situ measurements of pH, temperature, salinity, and dissolved oxygen were paired with daily fish catches in nearshore Alaskan waters of the Beaufort Sea. This dataset includes...

Data from: Separation of realized ecological niche axes among sympatric tilefishes provides insight into potential drivers of co‐occurrence in the NW Atlantic

Jill A. Olin, Oliver Shipley, Robert Cerrato, Paul Nitschke, Cedric Magen & Michael Frisk
Golden and Blueline Tilefish (Lopholatilus chamaeleonticeps and Caulolatilus microps) are keystone taxa in northwest (NW) Atlantic continental shelf‐edge environments due to their biotic (trophic‐mediated) and abiotic (ecosystem engineering) functional roles combined with high‐value fisheries. Despite this importance, the ecological niche dynamics (i.e., those relating to trophic behavior and food‐web interactions) of these sympatric species are poorly understood, knowledge of which may be consequential for maintaining both ecosystem function and fishery sustainability. We used stable isotope...

Differential activation of c-Fos and Egr1 during development of the mouse visual cortex

Alexander Lazutkin, Anna Ivanova, Pavel Rogozin, Grigori Enikolopov & Konstantin Anokhin
Critical periods (CP) in brain development are associated with profound changes in gene expression cascades. Here we examine the expression of the immediate early genes c-Fos and Egr1 at different stages of mouse visual cortex (VC) development. Mice 11, 25, and 50 days of age were maintained under standard light-dark conditions, deprived of light for 5 days, or deprived of light for 5 days and then exposed to light for 90 min. Their brains were...

Using 2D dental geometric morphometrics to identify modern Perognathus and Chaetodipus specimens (Rodentia, Heteromyidae)

Megan R Wyatt, Samantha S B Hopkins & Edward B Davis
The Heteromyidae (pocket mice and kangaroo rats) are a group of extant small rodents abundant in western North America, as well as in fossil assemblages over the last 20 million years. Two genera of heteromyids, Chaetodipus and Perognathus, share similar tooth morphology and teeth are the primary fossil remains. Previous genetic studies show these extant sister genera likely diverged in the middle Miocene (~16 million years ago); however, the Chaetodipus fossil record starts in the...

Supporting Data To: Shark tooth collagen stable isotopes (δ15N and δ13C) as ecological proxies

Oliver Shipley, Gregory Henkes, James Gelsleichter, Clark Morgan, Eric Schneider, Brendan Talwar & Michael Frisk
The isotopic composition of tooth-bound collagen has long been used to reconstruct dietary patterns of animals in extant and paleoecological systems. For sharks that replace teeth rapidly in a conveyor-like system, stable isotopes of tooth collagen (δ13Ctooth & δ15Ntooth) are poorly understood and lacking in ecological context relative to other non-lethally sampled tissues. This tissue holds promise, because shark jaws may preserve isotopic chronologies from which to infer individual-level ecological patterns across a range of...

Spatiotemporal study of iron oxide nanoparticle monolayer formation at liquid/liquid interfaces by using in situ small-angle x‐ray scattering

Jiayang Hu, Evan W. C. Spotte-Smith, Brady Pan, Roy J. Garcia, Carlos Colosqui & Irving P. Herman
Spatial and temporal small angle x-ray scattering (SAXS) scans show that 8.6 and 11.8 nm iron oxide nanoparticles (NPs) in heptane drop-cast on top of a heptane layer atop a diethylene glycol (DEG) layer are trapped at the DEG/heptane interface to generally form a single ordered, hexagonal close packed monolayer (ML), and this occurs long before the heptane evaporates. Many NPs remain dispersed in the heptane after this NP assembly. Assembly occurs faster than expected...

Lack of synchronized breeding success in a seabird community: extreme events, niche separation, and environmental variability

Casey Youngflesh, Yun Li, Heather Lynch, Karine Delord, Christophe Barbraud, Rubao Ji & Stephanie Jenouvrier
Synchrony in ecological systems, the degree to which elements respond similarly over time or space, can inform our understanding of how ecosystems function and how they are responding to global change. While studies of ecological synchrony are often focused on within-species dynamics, synchrony among species may provide important insights into how dynamics of one species are indicative of conditions relevant to the larger community, with both basic and applied implications. Ecological theory suggests there may...

Morphometric materials for analyzing Eulipotyphlans across the Paleocene-Eocene-Thermal Maximum

Natasha Vitek
Interpreting the impact of climate change on vertebrates in the fossil record can be complicated by the effects of potential biotic drivers on morphological patterns observed in taxa. One promising area where this impact can be assessed is a high-resolution terrestrial record from the Bighorn Basin, Wyoming, that corresponds to the Paleocene-Eocene Thermal Maximum (PETM), a geologically rapid (~170 ky) interval of sustained temperature and aridity shifts about 56 million years ago. The PETM has...

Telemetry validated nitrogen stable isotope clocks identify ocean-to-estuarine habitat shifts in mobile organisms

Oliver Shipley, Alisa Newton, Michael Frisk, Gregory Henkes, Jake LaBelle, Merry Camhi, Michael Hyatt, Hans Walters & Jill Olin
1. Throughout their life history, many animals transition among heterogenous environments to facilitate behaviors such as reproduction, foraging, and predator avoidance. The dynamic environmental and biological conditions experienced by mobile species are integrated in the chemical composition of their tissues, providing retrospective insight into movement. 2. Here, we present a unique nitrogen stable isotope clocks (‘isotopic clocks’), which integrate tissue turnover rates, consumer stable isotope ratios, and habitat-specific isotope baselines and can be used to...

Biodiversity across the Greater Cape Floristic Region

Henry Frye, Matthew Aiello-Lammens, Doug Euston-Brown, Cynthia Jones, Hayley Kilroy Mollmann, Merow Cory, Jasper Slingsby, Helga Van Der Merwe, Adam Wilson & John Silander
Aim: With plant biodiversity under global threat, there is an urgent need to monitor the spatial distribution of multiple axes of biodiversity. Remote sensing is a critical tool in this endeavor. One remote sensing approach in detecting biodiversity is based on the hypothesis that the spectral diversity of plant communities is a surrogate of multiple dimensions of biodiversity. We investigated the generality of this “surrogacy” for spectral, species, functional, and phylogenetic diversity across 1,267 plots...
