A dataset of 5 million city trees from 63 US cities: species, location, nativity status, health, and more.Dakota McCoy, Benjamin Goulet-Scott, Weilin Meng, Bulent Atahan, Hana Kiros, Misako Nishino & John Kartesz
Sustainable cities depend on urban forests. City trees improve our health, clean the air, store CO2, and cool local temperatures. Comparatively less is known about urban forests as ecosystems, particularly their spatial composition, nativity statuses, biodiversity, and tree health. Here, we assembled and standardized a new dataset of N=5,132,890 trees from 63 of the largest US cities. The data comes from street tree inventories conducted at the level of cities and/or neighborhoods. Each data sheet...
The Total Carbon Column Observing Network (TCCON) is a network of ground-based Fourier Transform Spectrometers that record direct solar absorption spectra of the atmosphere in the near-infrared. From these spectra, accurate and precise column-averaged abundances of atmospheric constituents including CO2, CH4, N2O, HF, CO, H2O, and HDO, are retrieved. This is the GGG2020 data release of observations from the TCCON station at California Institute of Technology, Pasadena, California, USA
Data from: Taxonomic scale and community organization impact observed latitudinal gradients of parasite diversityWhitney Preisser
Aim: While most free-living taxa follow the latitudinal diversity gradient (LDG), or the trend of higher diversity at lower latitudes, we know little about how the diversity of parasitic taxa is distributed across latitudes. To better understand the macroecological patterns of parasite diversity, we sought to determine if: 1) helminths follow the traditional LDG; 2) taxonomic resolution impacts observed patterns; 3) latitudinal patterns are consistent across levels of community organization; and 4) helminth diversity is...

The COVID-19 situation in Brazil is complex due to large differences in the shape and size of regional epidemics. Here we tested monthly blood donation samples for IgG antibodies from March 2020 to March 2021 in eight of Brazil’s most populous cities. The inferred attack rate of SARS-CoV-2 adjusted for seroreversion in December 2020, before the Gamma VOC was dominant, ranged from 19.3% (95% CrI 17.5% - 21.2%) in Curitiba to 75.0% (95% CrI 70.8%...
Cognitive flexibility is a core component of executive function, a suite of cognitive capacities that enables individuals to update their behavior in dynamic environments. Human executive functions are proposed to be enhanced compared to other species, but this inference is based primarily on neuroanatomical studies. To address this, we examined the nature and origins of cognitive flexibility in chimpanzees, our closest living relatives. Across three studies, we examined different components of cognitive flexibility using reversal...
Data from: Fixation and preservation contribute to distortion in vertebrate museum specimens: a ten-year study with the lizard Anolis sagreiR. Graham Reynolds, Inbar Maayan, Rachel M. Goodman, Paul M. Hime, Ryan Bickel, E. Allen Luck & Jonathan B. Losos
Preservation of museum specimens depends on chemical fixation and preservation, processes that might distort the original material. Relatively few studies have examined preservation effects in potentially susceptible soft-bodied taxa like herpetofauna, and those that have rarely extend over more than a few months. We collected six common morphological measurements from the same set of radiographed specimens of the Neotropical lizard Anolis sagrei over nearly ten years to investigate whether morphometric changes result from fixation in...
Herbivores balance forage acquisition with the need to avoid predation, often leading to tradeoffs between forgoing resources to avoid areas of high predation risk, or tolerating increased risk in exchange for improved forage. The outcome of these decisions is likely to change with varying resource levels, with herbivores altering their response to predation risk across heterogeneous landscapes. Such contrasting responses will alter the strength of non-consumptive predation effects, but are poorly understood in multiple- predator/multiple-prey...
Data and Materials : Summarizing Global SARS-CoV-2 Geographical Spread by Phylogenetic Multitype Branching ModelsHao Chi Kiang , Krzysztof Bartoszek, Sebastian Sakowski, Stefano Iacus & Michele Vespe
Raw numerical results, phylogeny, and related data for the conference proceeding article "Summarizing Global SARS-CoV-2 Geographical Spread by Phylogenetic Multitype Branching Models".
Combinations of correlated floral traits have arisen repeatedly across angiosperms through convergent evolution in response to pollinator selection to optimize reproduction. While some plant groups exhibit very distinct combinations of traits adapted to specific pollinators (so-called pollination syndromes), others do not. Determining how floral traits diverge across clades and whether floral traits show predictable correlations in diverse groups of flowering plants is key to determining the extent to which pollinator-mediated selection drives diversification. The North...
