Abundance predominates over niche factors as determinant of the frequency of interactions between frugivorous birds and plants

Marco Aurelio Pizo, Tomas Carlo, Aarón González-Castro & Antonio Fontanella
Neutral and niche factors influence the structure of frugivory and seed dispersal networks. While the former refers to the abundance of interacting species, niche factors refer to traits that mediate interactions between species (e.g., morphology). The challenge is to unravel in which circumstances one kind of factor predominates over the other, or how much variation is explained by each factor. We investigated the relative contributions of abundance and trait-matching (considering fruit’s size, pulp mass to...

Strategies to Mitigate Enteric Methane Emissions by Ruminants

C. Arndt, A.N. Hristov, W.J. Price, S.C. McClelland, A.M. Pelaez, A.R. Bayat, L.A. Crompton, J. Dijkstra, M.A. Eugène, D. Enahoro, E. Kebreab, M. Kreuzer, M. McGee, C. Martin, C.J. Newbold, C.K. Reynolds, A. Schwarm, K.J. Shingfield, J.B. Veneman, D.R. Yáñez-Ruiz & Z. Yu
To meet the 1.5°C target, methane (CH4) from ruminants must be reduced by 11 to 30% of the 2010 level by 2030 and by 24 to 47% by 2050. A meta-analysis identified strategies to decrease product-based [PB; CH4 per unit meat or milk (CH4I)] and absolute (ABS) enteric CH4 emissions while maintaining or increasing animal productivity (AP; weight gain and milk yield). Next the potential of different adoption rates of one PB and/or ABS strategies...

Stranger danger: A meta-analysis of the dear enemy hypothesis

Jo Werba, Adam Stuckert, Matthew Edwards & Michael McCoy
The dear enemy hypothesis predicts that territorial individuals will be less aggressive toward known neighbors than to strangers. This hypothesis has been well studied and there is a wealth of data demonstrating its prevelance among some taxa. However, a quantitative synthesis is needed to test the generality of the phenomenon, identify key mechanisms driving the behavior, and guide future research. Here we made a comprehensive collection of Dear Enemy data from 138 studies representing 105...

Evidence from automixis with inverted meiosis for the maintenance of sex by loss of complementation

Marco Archetti
The adaptive value of sexual reproduction is still debated. A short-term disadvantage of asexual reproduction is loss of heterozygosity, which leads to the unmasking of recessive deleterious mutations. The cost of this loss of complementation is predicted to be higher than the twofold cost of meiosis for most types of asexual reproduction. Automixis with terminal fusion of sister nuclei is especially vulnerable to the effect of loss of complementation. It is found, however, in some...

Representations of the Working Class in Trump-Era Advertising

Matthew P. McAllister
This essay argues that in the early- to mid-Trump era – starting with his active campaign for the US Presidency in 2015 and through his subsequent administration pre-Covid through February 2020 – working-class bodies were used in advertising to both contest and enact prominent values and ideological tensions that became prominent during Trump’s reign. Advertising used class-based representations in several ways: to critique Trump and his policies; to depict working-class hardships under Trump; and, conversely,...

Data from: An integrative skeletal and paleogenomic analysis of stature variation suggests relatively reduced health for early European farmers

Stephanie Marciniak, Christina Bergey, Ana Maria Silva, Agata Hałuszko, Mirosław Furmanek, Barbara Veselka, Petr Velemínský, Giuseppe Vercellotti, Joachim Wahl, Gunita Zarina, Cristina Longhi, Jan Kolář, Rafael Garrido-Pena, Raúl Flores-Fernández, Ana M.

Perry
Human culture, biology, and health were shaped dramatically by the onset of agriculture ~12,000 years before present (BP). This shift is hypothesized to have resulted in increased individual fitness and population growth as evidenced by archaeological and population genomic data alongside a decline in physiological health as inferred from skeletal remains. Here, we consider osteological and ancient DNA data from the same prehistoric individuals to study human stature variation as a proxy for health across...

Extreme hydroxyl amounts generated by thunderstorm-induced corona on grounded metal objects

W.H. Brune, J.M. Jenkins, G.A. Olson, P.J. McFarland, D.O. Miller, J. Mao & X. Ren
It has now been established that atmospheric electrical discharges generate unexpectedly large amounts of the atmosphere’s primary oxidant, hydroxyl (OH) in thunderstorm anvils, where lightning and weak electrical discharges are caused by atmospheric charge separation. The question is “Do other atmospheric electrical discharges also generate large amounts of oxidants?’ In this paper, we demonstrate that coronas formed on grounded metal objects produce extreme amounts of hydroxyl (OH), hydroperoxyl (HO2), and ozone (O3) when thunderstorms are...

Data and Rscripts from: An integrated experimental and mathematical approach to inferring the role of food exploitation and interference interactions in shaping life history

Barbara Joncour, William Nelson, Damie Pak & Ottar Bjornstad
Intraspecific interactions can occur through many ways but the mechanisms can be broadly categorized as food exploitation and interference interactions. Identifying how intraspecific interactions impact life history is crucial to accurately predict how population density and structure influence dynamics. However, disentangling the effects of interference interactions from exploitation using experiments, is challenging for most biological systems. Here we propose an approach that combines experiments with modeling to infer the pathways of intraspecific interactions in a...

Complex floral traits shape pollinator attraction to ornamental plants

Emily Erickson, Robert Junker, Jared Ali, Nathaniel McCartney, Harland Patch & Christina Grozinger
Background and Aims Ornamental flowering plant species are often used in managed greenspaces to attract and support pollinator populations. In natural systems, selection by pollinators is hypothesized to result in convergent multimodal floral phenotypes that are more attractive to specific pollinator taxa. In contrast, ornamental cultivars are bred via artificial selection by humans, and exhibit diverse and distinct phenotypes. Despite their prevalence in managed habitats, the influence of cultivar phenotypic variation on plant attractiveness to...

Ecologies of Transdisciplinary Research

Paul Shrivastava, Laszlo Zsolnai, David Wasieleski & Philippe Mairesse
We are scholars of economics, business , and sustainability. For the past two decades we have been doing transdisciplinary work individually and jointly. In this essay we share some key lessons that we have learned about the ecologies of transdisciplinary work. We consider transdisciplinarity to be qualitatively different from interdisciplinarity or multidisciplinarity in several crucial ways. Transdisciplinary work takes its problems from the real world and not disciplinary gaps in knowledge or combining disciplines for...

Supplementary data, code, and information for ‘False Hope: The rate of global temperature rise may have hit a plateau, but a climate crisis still looms in the near future’ (Scientific American, Mann 2014)

M. Mann
“Temperatures have been flat for 15 years—nobody can properly explain it,” the Wall Street Journal says. “Global warming ‘pause’ may last for 20 more years, and Arctic sea ice has already started to recover,” the Daily Mail says. Such reassuring claims about climate abound in the popular media, but they are misleading at best. Global warming continues unabated, and it remains an urgent problem. The misunderstanding stems from data showing that during the past decade...

Turley NE, Biddinger DJ, Joshi NK, López-Uribe MM. 2022. Six years of wild bee monitoring shows changes in biodiversity within and across years and declines in abundance. Ecology and Evolution. Wild bees form diverse communities that pollinate plants in both native and agricultural ecosystems making them both ecologically and economically important. The growing evidence of bee declines has sparked increased interest in monitoring bee community and population dynamics using standardized methods. Here, we studied the...

Combining GWAS and population genomic analyses to characterize coevolution in a legume-rhizobia symbiosis

Brendan Epstein, Liana Burghardt, Katy Heath, Michael Grillo, Adam Kostanecki, Tuomas Hämälä, Nevin Young & Peter Tiffin
The mutualism between legumes and rhizobia is clearly the product of past coevolution. However, the nature of ongoing evolution between these partners is less clear. To characterize the nature of recent coevolution between legumes and rhizobia, we used population genomic analysis to characterize selection on functionally annotated symbiosis genes as well as on symbiosis gene candidates identified through a two-species association analysis. For the association analysis, we inoculated each of 202 accessions of the legume...

Pharmacological mechanism and therapeutic efficacy of Icariside II in the treatment of acute ischemic stroke: a systematic review and network pharmacological analysis

Xu Wang, Jinjian Li, Lifang Liu, Jun-Ming Kan, Ping Niu, Zi-Qiao Yu, Chunyu Ma, Fuxiang Dong, Mo-Xuan Han, Jinhua Li & De-xi Zhao
Abstract Background and objective Epimedii has long been used as a traditional medicine in Asia for the treatment of various common diseases, including Alzheimer's disease, cancer, erectile dysfunction, and stroke. Studies have reported the ameliorative effects of Icariside II (ICS II), a major metabolite of Epimedii, on acute ischemic stroke (AIS) in animal models. Based on network pharmacology, molecular docking, and molecular dynamics (MD) simulations, we conducted a systematic review to evaluate the effects and...

A.B. Burton & A.R. Kemanian
This dataset and accompanying supplemental materials are companion pieces to the journal article “Assessing a century of maize and soybean polyculture for silage production” published in Agronomy Journal in 2022 by Burton & Kemanian. Maize (Zea mays L.) silage is an important source of feed for ruminant animals. However, maize monocultures are exposed to both abiotic and biotic stresses that can reduce yield and contribute to environmental degradation. Over the past century, maize + soy...

Seesaw production and pollution associated with COVID-19-like supply chain disruptions in an agroecosystem model, Cycles Data

R. Rozum
Sudden global disruptions in agricultural commodities demand or input supply have local immediate effects on the economy and the environment. Recognizing these patterns can help society and agricultural stakeholders prepare and react to these disruptions. This research addresses the use of agricultural decision support systems (DSS) to quickly assess the impacts of disruptions like the COVID-19 pandemic on agroecosystem production output and pollution. We diagnosed the effect of assumed labor and agrochemical supply disruptions on...

Competing controls of fluid overpressurization and chloritization on strength and instability of faults in granite: Implications for seismicity triggered by fluid-injection

Fengshou Zhang, Rui Huang, Mengke An, Ki-Bok Min, Derek Elsworth, Hannes Hofmann & Xiaoguang Wang
Fluids injection for hydraulic stimulation and fracturing, typical in the development of enhanced geothermal systems (EGS) in granites, can reactivate deep faults and induce seismicity. Such faults typically contain chlorite coatings as an alteration product that may impact styles of deformation – aseismic through seismic. We performed shear experiments on simulated granite fault gouges under conditions typifying a geothermal reservoir at ~4 km depth with a confining pressure of 110 MPa, a temperature of 150℃,...

Data for Coco et al. 2022 Oecologia, More phylogenetically diverse polycultures inconsistently suppress insect herbivore populations

A.M. Coco, E.C. Yip, I. Kaplan & J.F. Tooker
Because the diet of many herbivorous insects is restricted to closely related taxa with similar chemistry, intercropping with diverse plant communities may reduce both pest populations and reliance on chemical pesticides in agroecosystems. We tested whether the effectiveness of intercropping against herbivorous insects depends on the phylogenetic relatedness of neighboring crops, using butternut squash (Cucurbita moschata) as a focal crop species in a series of different intercropping combinations. We found that increased phylogenetic divergence of...

Ignoring species availability biases occupancy estimates in single-scale occupancy models

Graziella DiRenzo, David Miller & Evan Grant
1. Most applications of single-scale occupancy models do not differentiate between availability and detectability, even though species availability is rarely equal to one. Species availability can be estimated using multi-scale occupancy models, and the availability process includes elements of species movement, behavior, and phenology. However, for the practical application of multi-scale occupancy models, it can be unclear what a robust sampling design looks like and what the statistical properties of the multi-scale and single-scale occupancy...

Prodigious amounts of hydrogen oxides generated by corona discharges on tree leaves

J.M. Jenkins, G.A. Olson, P.J. McFarland & W.H. Brune
Prodigious amounts of the hydroxyl radical (OH) are generated by weak electrical discharges, such as corona discharges induced on trees during thunderstorms. As was observed in studies of sparks and subvisible discharges, corona discharges on leaves produce OH and hydroperoxyl (HO2) amounts that are several orders of magnitude larger than usual. Our laboratory studies demonstrate that production rates of OH and HO2 depend on the applied electric field that generates the corona discharge, leaf dryness,...

Supplementary data, code, and information for ‘Global Temperature Patterns in Past Centuries: An interactive presentation’ (Earth Interactions, Mann et al. 2000)

M. Mann, E. Gille, R. Bradley, M. Hughes, J. Overpeck, F. Keimig & W. Gross
The recent availability of global networks of annual or seasonal resolution proxy data, combined with the few long instrumental and historical climate records available during the past few centuries, make it possible now to reconstruct annual and seasonal spatial patterns of temperature variation, as well as hemispheric, global-mean, and regional temperature trends, several centuries back in time. Reconstructions of large-scale global or hemispheric trends during centuries past can place the instrumental assessments of climate during...
