Complex landscapes stabilize farm bird communities and their expected ecosystem services

Olivia Smith, Christina M. Kennedy, Alejandra Echeverri, Daniel Karp, Christopher Latimer, Joseph Taylor, Erin Wilson-Rankin, Jeb Owen & William Snyder
1. Birds play many roles within agroecosystems including as consumers of crops and pests, carriers of pathogens, and beloved icons. Birds are also rapidly declining across North America, in part due to agricultural intensification. Thus, it is imperative to identify how to manage agroecosystems to best support birds for multi-functional outcomes (e.g., crop production and conservation). Both the average amounts of services/disservices provided and their temporal stability are important for effective farm planning. 2. Here,...

Spatial allocation without spatial recruitment in bumblebees

Darren Incorvaia, Arend Hintze & Fred Dyer
Any foraging animal is expected to allocate its efforts among resource patches that vary in quality across time and space. For social insects, this problem is shifted to the colony level: the task of allocating foraging workers to the best patches currently available. To deal with this task, honeybees rely upon differential recruitment via the dance language, while some ants use differential recruitment on odor trails. Bumblebees, close relatives of honeybees, should also benefit from...

Plant-soil feedback and crop rotation

Akihiro Koyama, Pedro Antunes & Teresa Dias
Plant-soil feedback (PSF) can be a major driver of plant performance in communities, and this concept can be used in selecting crop rotation sequences to maximize agricultural yields. Potential benefits of using PSF in this context include nutrient use optimization, pathogen reduction and enhancement of mutualisms between crops and microbes. Yet, the contributions of these combined mechanisms are poorly understood. Here we investigated the relative contributions of these mechanisms using five major crops commonly cultivated...

Inbreeding depression contributes to the maintenance of habitat segregation between closely related monkeyflower species

Katherine Toll, Eric Francis LoPresti & David Bryant Lowry
Incompletely reproductively isolated species often segregate into different microhabitats, even when they are able to survive and reproduce in both habitats. Longer term evolutionary factors may contribute to this lack of cross-habitat persistence. When reproductive interference reduces immigrant fitness, assortative mating, including self-fertilization, increases immigrants’ fitness in a single generation, but longer-term, inbreeding depression may reduce the chance of population persistence. Two California monkeyflower species repeatedly segregate into drier and wetter areas in their zone...

Data from: Signatures of north-eastern expansion and multiple refugia: Genomic phylogeography of the Pine Barrens Treefrog, Hyla andersonii (Anura: Hylidae)

Alexa Warwick, Lisa Barrow, Megan Smith, D. Bruce Means, Alan Lemmon & Emily Lemmon
Range fragmentation poses challenges for species persistence over time and may be caused by both historical and contemporary processes. We combined genomic data, phylogeographic model testing, and paleoclimate niche modeling to infer the evolutionary history of the Pine Barrens Treefrog (Hyla andersonii), a seepage bog specialist, in eastern North America to better understand the historical context of its fragmented distribution. We sampled H. andersonii populations across the three disjunct regions of the species’ range: Alabama/Florida...

10-year trends reveal declining quality of seeded pollinator habitat on reclaimed mines regardless of seed mix diversity

Andrew Lybbert, Sarah Cusser, Keng-Lou Hung & Karen Goodell
Plant-pollinator interactions represent a crucial ecosystem function threatened by anthropogenic landscape alterations. Disturbances that reduce plant diversity are associated with floral resource and pollinator declines. Establishing wildflower plantings is a major conservation strategy targeting pollinators, the success of which depends on long-term persistence of seeded floral communities. However, most pollinator-oriented seeding projects are monitored for a few years, making it difficult to evaluate the longevity of such interventions. Selecting plant species to provide pollinators diverse...

Cytb + ND2 Prinia gracilis complex

Per Alstrom, Pamela Rasmussen, Canwei Xia, Lijun Zhang, Jesper Magnusson, Arya Shafaeipour & Urban Olsson
Prinias (Cisticolidae: Prinia) are resident warblers of open areas across Africa and Asia and include many polytypic species whose species limits have not been seriously reevaluated recently. Based on an integrative taxonomic analysis of morphology, song, and mitochondrial DNA (mtDNA), we suggest that 2 species should be recognized in the Graceful Prinia (Prinia gracilis) complex. In addition, our morphological analyses show the existence of a well-marked undescribed form in southeastern Somalia, which we name herein...

Market forces determine the distribution of a leaky function in a simple microbial community

Jeffrey Morris, Sarah Adkins-Jablonsky, Colleen Clark, Matthew Kuhl & Spiridon Papoulis
Many biological functions are leaky, and organisms that perform them contribute some of their products to a community "marketplace" where non-performing individuals may compete for them. Leaky functions are partitioned unequally in microbial communities, and the evolutionary forces determining which species perform them and which become beneficiaries are poorly understood. Here we demonstrate that the market principle of comparative advantage determines the distribution of a leaky antibiotic resistance gene in an environment occupied by two...

Asymmetric responses of resource use efficiency to previous-year precipitation in a semi-arid grassland

Juanjuan Han, Jiquan Chen, Weiyu Shi, Jian Song, Dafeng Hui, Jingyi Ru & Shiqiang Wan
1. Intensified inter-annual fluctuations in precipitation could profoundly impact terrestrial ecosystems. However, how changes previous-year precipitation influence current ecosystem functioning (e.g., resource use efficiency) in semi-arid regions remains unclear. 2. In this study, water use efficiency (WUE) and light use efficiency (LUE) were investigated in a multi-year precipitation gradient experiment with seven treatment levels: 20%, 40% and 60% decreases and 20%, 40% and 60% increases in the amount of natural rainfall plus ambient precipitation. Plots...

Soil resources mediate the strength of species but not trait convergence across grassland restorations

Christopher Catano, Tyler Basset, Jonathan Bauer, Emily Grman, Anna Groves, Chad Zirbel & Lars Brudvig
Ecological restoration is notoriously unpredictable because similar actions can result in different outcomes. Outcomes can also differ for species and functional components of communities depending on how restoration actions and abiotic conditions alter community assembly trajectories. Quantifying variation in community trajectories across restorations for both species and traits is rare, but can help to resolve underlying assembly processes and refine strategies to maximize restoration success. We quantified the importance of soil resources, seed mix richness,...

Data from: Hybridization alters growth and migratory life history expression of native trout

Jeffrey T. Strait, Lisa A. Eby, Ryan P. Kovach, Clint C. Muhlfeld, Matthew C. Boyer, Stephen J. Amish, Seth Smith, Winsor H. Lowe & Gordon Luikart
Human-mediated hybridization threatens many native species, but the effects of introgressive hybridization on life history expression are rarely quantified, especially in vertebrates. We quantified the effects of non-native rainbow trout admixture on important life history traits including growth and partial migration behavior in three populations of westslope cutthroat trout over five years. Rainbow trout admixture was associated with increased summer growth rates in all populations, and decreased spring growth rates in two populations with cooler...

Phylogenomics in the hard pines (Pinus subsection Ponderosae; Pinaceae) confirms paraphyly in Pinus ponderosa, and places Pinus jeffreyi with the California big cone pines

Ann Willyard, David S. Gernandt, Blake Cooper, Connor Douglas, Kristen Finch, Hassan Karemera, Erik Lindberg, Stephen K. Langer, Julia Lefler, Paula Marquardt, Dakota Pouncey & Frank Telewski
We sampled 130 individuals (2 to 25 per taxon) of subsections Ponderosae and Sabinianae. Nucleotide sequences were obtained by targeting 703 low copy nuclear genes. From the unenriched portion of the short reads, we assembled nearly complete plastome nucleotide sequences. We used 600 nuclear genes and the plastome sequences to create phylogenies and species trees that we compared to evaluate cytonuclear concordance and reticulation. We found that Pinus jeffreyi belongs with subsect. Sabinianae based on...

Location and plant spacing affect biomass yield and nutritional value of pigeon pea forage

Mekonen Tefera, Tolera Adugna, Nurfeta Ajebu, Bradford Barry & Mekasha Aklilu
An experiment was conducted to evaluate the effects of row spacing (RS) and interplant spacing (IPS) on the yield of total biomass, leaf, and edible twigs, and nutritive value of pigeon pea,(Cajanus cajan L. Millsp.) at three locations in the Rift Valley area of Ethiopia, using a randomized completed block design with three replications in 3 × 3 factorial arrangement; three RS ( 25, 50, and 75 cm) and three IPS (15, 30, and 45...

Reservoir hosts experiencing food stress alter transmission dynamics for a zoonotic pathogen

Jennifer C. Owen, Hannah R. Landwerlen, Dhruv B. Sharma, Sichao Wang, Alexander T. Ciota, Laura D. Kramer, Alan P. Dupuis & Aniruddha V. Belsare
Anthropogenic environmental change can significantly alter availability and quality of food resources for reservoir hosts and impact host-pathogen interactions in the wild. The state of the host’s nutritional reserves as time of infection is a key factor influencing infection outcomes by altering host resistance. Here we combine experimental and model-based approaches to better understand how an environmental stressor affects host resistance to West Nile virus (WNV). Using American robins (Turdus migratorius), a species considered a...

Aquatic foods from marine and freshwater systems are critical to the nutrition, health, livelihoods, economies and culture of billions of people worldwide – but climate-related hazards may compromise their ability to provide these benefits. This analysis estimates national-level aquatic food system climate risk using a fuzzy logic modeling approach that connects climate hazards impacting marine and freshwater capture fisheries and aquaculture to their contributions to sustainable food system outcomes, and vulnerability to losing those contributions....

Targeted lipidomics yields changes in both arachidonic acid and linoleic acid pathways observed in C57BL/6J mice compared to KitW-sh mice after nitrogen mustard exposure

Angela Cruz-Hernandez, Jared Brown, Ryan Mendoza, Kathleen Nguyen, Christopher Evans, Anna Harder, Alison Bauer & Neera Tewari-Singh
Sulfur mustard (SM) has been widely used as a chemical warfare agent including most recently in Syria. Mice exposed to SM exhibit an increase in pro-inflammatory cytokines followed by immune cell infiltration in the lung, however, the mechanisms leading to these inflammatory responses has not been completely elucidated. Mast cells are one of the first responding innate immune cells found at the mucosal surfaces of the lung and have been reported to be activated by...

Evolution of conserved noncoding sequences in Arabidopsis thaliana

Alan Yocca, Zefu Lu, Robert Schmitz, Michael Freeling & Patrick Edger
Recent pangenome studies have revealed that a large fraction (>20%) of the gene content within a species exhibits presence-absence variation (PAV). However, coding regions alone provide an incomplete assessment of functional genomic sequence variation at the species level. Little to no attention has been paid to noncoding regulatory regions in pangenome studies, though these sequences directly modulate gene expression and phenotype. To uncover regulatory genetic variation, we generated chromosome-scale genome assemblies for thirty Arabidopsis thaliana...

Phosphorus availability and leaching losses in annual and perennial cropping systems in an upper US Midwest landscape

Mir Zaman Hussain, Stephen Hamilton, G. Philip Robertson & Bruno Basso
Excessive phosphorus (P) applications to croplands can contribute to eutrophication of surface waters through surface runoff and subsurface (leaching) losses. We analyzed leaching losses of total dissolved P (TDP) from no-till corn, hybrid poplar (Populus nigra X P. maximowiczii), switchgrass (Panicum virgatum), miscanthus (Miscanthus giganteus), native grasses, and restored prairie, all planted in 2008 on former cropland in Michigan, USA. All crops except corn (13 kg P ha−1 year−1) were grown without P fertilization. Biomass...

Daily ranging and den usage patterns structure fission-fusion dynamics and social associations in spotted hyenas

Eli Strauss, Frants Jensen, Andrew Gersick, Mara Thomas, Kay Holekamp & Ariana Strandburg-Peshkin
Environment structure often shapes social interactions. Spatial attractors that draw multiple individuals may play a particularly important role in dispersed groups, where individuals must first encounter one another to interact. We use GPS data recorded simultaneously from five spotted hyenas (Crocuta crocuta) within a single clan to investigate how communal dens and daily ranging patterns shape fission-fusion dynamics (subgroup splits and merges). We introduce a species-general framework for identifying and characterizing dyadic fission-fusion events and...

Pupil and gaze during binocular rivalry

Jan Brascamp
The pupil provides a rich, non-invasive measure of the neural bases of perception and cognition, and has been of particular value in uncovering the role of arousal-linked neuromodulation, which alters cortical processing as well as pupil size. But pupil size is subject to a multitude of influences, which complicates unique interpretation. We measured pupils of observers experiencing perceptual multistability -- an ever-changing subjective percept in the face of unchanging but inconclusive sensory input. In separate...

Extirpated prairie species demonstrate more variable phenological responses to warming than extant congeners

Meredith Zettlemoyer, Katarina Renaldi, Michael Muzyka & Jennifer Lau
Premise of the study. Shifting phenology in response to climate is one mechanism that can promote population persistence and geographic spread; therefore, species with limited ability to phenologically track changing environmental conditions may be more susceptible to population declines. Alternatively, apparently, nonresponding species may demonstrate divergent responses to multiple environmental conditions experienced across seasons. Methods. Capitalizing on herbarium records from across the Midwestern United States and detailed botanical surveys documenting local extinctions over the past...

Data from: Nitrification is a minor source of nitrous oxide (N2O) in an agricultural landscape and declines with increasing management intensity

Di Liang & G. Philip Robertson
The long-term contribution of nitrification to nitrous oxide (N2O) emissions from terrestrial ecosystems is poorly known and thus poorly constrained in biogeochemical models. Here, using Bayesian inference to couple 25 years of in situ N2O flux measurements with site-specific Michaelis-Menten kinetics of nitrification-derived N2O, we test the relative importance of nitrification-derived N2O across six cropped and unmanaged ecosystems along a management intensity gradient in the U.S. Midwest. We found that the maximum potential contribution from...

Heating Arrays Aboveground Biomass Data

Louis Jochems, Jennifer Lau, Lars Brudvig & Emily Grman
Restoration in this era of climate change comes with a new challenge: anticipating how best to restore populations to persist under future climate conditions. Specifically, it remains unknown whether locally-adapted or warm-adapted seeds best promote native plant community restoration in the warmer conditions predicted in the future and whether local or warm-adapted soil microbial communities could mitigate plant responses to warming. This may be especially relevant for biomes spanning large climatic gradients, such as the...

eDNA metabarcoding in lakes to quantify influences of landscape features and human activity on aquatic invasive species prevalence and fish community diversity

Lilian Pukk, Jeannette Kanefsky, Amanda Heathman, Ellen Weise, Lucas Nathan, Seth Herbst, Nicholas Sard, Kim Scribner & John Robinson
Aim: Our goal was to use eDNA metabarcoding to characterize fish community diversity, detect aquatic invasive species (AIS), and assess how measures of community (or AIS) diversity are influenced by lake physical and environmental covariates, measures of hydrological connectivity, and human accessibility. Location: Michigan, USA. Methods: eDNA samples collected from 22 lakes were sequenced using two mitochondrial gene regions (12S and 16S rRNA). Metabarcoding data were compared to traditional fisheries survey data for a subset...

Capture data for American Robins (Turdus migratorius) at a fall migration banding station in Mid-Michigan from 2012 - 2019

Jennifer Owen
At the Burke Lake Banding Station in Bath, Michigan we captured American robins (Turdus migratorius) during fall migration from 2011 to 2019. The data shared consists of capture date and age. The data are used only for looking at the relative ratio of hatching year (HY) to after-hatching year (AHY) robins captured during fall migration.
