Data from: Canopy tree preference by insectivorous birds in shade-coffee farms: implications for migratory bird conservation

Desirée L. Narango, Douglas W. Tallamy, Kerry J. Snyder & Robert A. Rice
Land converted to coffee agriculture occupies >5 million hectares of what was once prime overwintering natural habitat in the American Neotropics for migrating birds. When tree canopy is retained or restored (i.e. shade-grown), coffee farms can serve as habitat refuge for wildlife. Yet few studies have examined whether canopy tree identity impacts habitat quality for biodiversity. Specifically, whether or not certain tree species are disproportionately important for foraging insectivorous birds remains unclear. In this study,...

Invasive grass (Microstegium vimineum) indirectly benefits spider community by subsidizing available prey

Andrew Landsman, Karin Burghardt & Jacob Bowman
1. Invasive plant species cause a suite of direct, negative ecological impacts, but subsequent, indirect effects are more complex and difficult to detect. Where identified, indirect effects to other taxa can be wide-ranging and include ecological benefits in certain habitats or locations. 2. Here, we simultaneously examine the direct and indirect effects of a common, invasive grass species (Microstegium vimineum) on the invertebrate communities of understory deciduous forests in the eastern United States. To do...

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...

Winds aloft over three water bodies influence spring stopover distributions of migrating birds along the Gulf of Mexico coast

Hannah Clipp, Jeffrey Buler, Jaclyn Smolinsky, Kyle Horton, Andrew Farnsworth & Emily Cohen
Migrating birds contend with dynamic wind conditions that ultimately influence most aspects of their migration, from broad-scale movements to individual decisions about where to rest and refuel. We used weather surveillance radar data to measure spring stopover distributions of northward migrating birds along the northern Gulf of Mexico coast and found a strong influence of winds over non-adjacent water bodies, the Caribbean Sea and Atlantic Ocean, along with the contiguous Gulf of Mexico. Specifically, we...

Improved household living standards can restore dry tropical forests

Ruth DeFries, Meghna Agarwala, Sandra Baquie, Pooja Choksi, Sarika Khanwilkar, Pinki Mondal, Harini Nagendra & Johannes Uperlainen.
Despite multiple approaches over the last several decades to harmonize conservation and development goals in the tropics, forest-depende­­­­­­nt households remain the poorest in the world. Durable housing and alternatives to fuelwood for cooking are critical needs to reduce multi-dimensional poverty. These improvements also potentially reduce pressure on forests and alleviate forest degradation. We test this possibility in dry tropical forests of the Central Indian Highlands where tribal and other marginalized populations rely on forests for...

Living and fossil Ginkgo leaves

Luke Mander, Haibin Hang, Martin Bauer & Washington Mio
The data presented here are a collection of images of living and fossil Ginkgo leaves. Mature and fully expanded leaves were harvested from a reproductively immature Ginkgo biloba tree growing in partial shade as a specimen on the campus of The Open University, UK. The specimen was ascended using a ladder and seven branches growing towards the West at approximately halfway up the specimen were removed from the trunk using a saw. Every leaf growing...

Data from: Acidification and γ-aminobutyric acid independently alter kairomone-induced behaviour

Corie L. Charpentier & Jonathan H. Cohen
Exposure to high pCO2 or low pH alters sensation and behaviour in many marine animals. We show that crab larvae lose their ability to detect and/or process predator kairomones after exposure to low pH over a time scale relevant to diel pH cycles in coastal environments. Previous work suggests that acidification affects sensation and behaviour through altered neural function, specifically the action of γ-aminobutyric acid (GABA), because a GABA antagonist, gabazine, restores the original behaviour....

Data from: Post‐independence mortality of juveniles is driven by anthropogenic hazards for two passerines in an urban landscape

Solny A. Adalsteinsson, Jeffrey J. Buler, Jacob L. Bowman, Vincent D'Amico, Zachary S. Ladin & W. Gregory Shriver
Urban environments impose novel selection pressures with varying impacts across species and life history stages. The post‐fledging stage for migratory passerines, defined as the period of time from when hatch‐year birds fledge until their first migration, is a poorly understood component of annual productivity that potentially limits population growth. We studied two migratory passerines with positive and negative population responses to urbanization, respectively: Gray Catbird (Dumetella carolinensis) and Wood Thrush (Hylocichla mustelina). Our goals were...

Data from: Shark movement strategies influence poaching risk and can guide enforcement decisions in a large, remote Marine Protected Area

David Jacoby, Francesco Ferretti, Robin Freeman, Aaron Carlisle, Taylor Chapple, David Curnick, Jonathan Dale, Robert Schallert, David Tickler & Barbara Block
Large, remote marine protected areas (MPAs) containing both reef and pelagic habitats, have been shown to offer considerable refuge to populations of reef-associated sharks. Many large MPAs are, however, impacted by illegal fishing activity conducted by unlicensed vessels. While enforcement of these reserves is often expensive, it would likely benefit from the integration of ecological data on the mobile animals they are designed to protect. Consequently, shark populations in some protected areas continue to decline,...

Haemosporidian parasites of Neotropical birds: causes and consequences of infection

Vincenzo A. Ellis, Alan Fecchio & Robert E. Ricklefs
Haemosporidian parasites of the genera Plasmodium, Haemoproteus, and Leucocytozoon are among the best studied parasites of Neotropical birds. Here, we describe variation in haemosporidian prevalence (i.e., the proportion of infected birds in a sampled population) in Neotropical birds. We review correlates of haemosporidian prevalence (including several avian life-history traits, climate, and season) and the population and evolutionary consequences of infection for Neotropical birds. We find that prevalence varies among avian taxonomic families, genera, and even...

A Unified Framework for Specification Tests of Continuous Treatment Effect Models

Wei Huang, Oliver Linton & Zheng Zhang
We propose a general framework for the specification testing of continuous treatment effect models. We assume a general residual function, which includes the average and quantile treatment effect models as special cases. The null models are identified under the unconfoundedness condition and contain a nonparametric weighting function. We propose a test statistic for the null model in which the weighting function is estimated by solving an expanding set of moment equations. We establish the asymptotic...

Climate trends and behavior of a model Amazonian terrestrial insectivore, Black-faced Antthrush, indicate adjustment to hot and dry conditions

Vitek Jirinec, Elisa Elizondo, Patricia Rodrigues & Philip Stouffer
Rainforest loss threatens terrestrial insectivorous birds throughout the world’s tropics. Recent evidence suggests these birds are declining in undisturbed Amazonian rainforest, possibly due to climate change. Here, we first asked whether Amazonian terrestrial insectivorous birds were exposed to increasingly extreme ambient conditions using 38 years of climate data. We found long-term trends in temperature and precipitation at our study site, especially in the dry season, which was ~1.3 °C hotter and 21% drier in 2019...

Using weather radar to help minimize wind energy impacts on nocturnally migrating birds

Emily B. Cohen, Jeffrey Buler, Kyle G. Horton, Scott R. Loss, Sergio A. Cabrera‐Cruz, Jaclyn A. Smolinsky & Peter P. Marra
As wind energy rapidly expands worldwide, information to minimize impacts of this development on biodiversity is urgently needed. Here we demonstrate how data collected by weather radar networks can inform placement and operation of wind facilities to reduce collisions and minimize habitat-related impacts for nocturnally migrating birds. We found over a third of nocturnal migrants flew through altitudes within the rotor-swept zone surrounding the North American Great Lakes, a continentally important migration corridor. Migrating birds...

Data from: Hallauer's Tusón: a decade of selection for tropical- to-temperate phenological adaptation in maize

Juliana E. C. Teixeira, Teclemariam Weldekidan, Natalia De Leon, Sherry Flint-Garcia, James B. Holland, Nick Lauter, Seth C. Murray, Wenwei Xu, David A. Hessel, Adrienne E. Kleintop, James A. Hawk, Arnel R. Hallauer & Randall J. Wisser
Crop species exhibit an astounding capacity for environmental adaptation, but genetic bottlenecks resulting from intense selection for adaptation and productivity can lead to a genetically vulnerable crop. Improving the genetic resiliency of temperate maize depends upon the use of tropical germplasm, which harbors a rich source of natural allelic diversity. Here, the adaptation process was studied in a tropical maize population subjected to 10 recurrent generations of directional selection for early flowering in a single...

Colony fitness increases in the honey bee at queen mating frequencies higher than genetic diversity asymptote

Keith S. Delaplane, J. Krispn Given, John Menz & Deborah A. Delaney
Abstract Across the eusocial Hymenoptera, a queen’s mating frequency is positively associated with her workers’ genetic diversity and colony’s fitness. Over 90% of a colony’s diversity potential is achieved by its mother’s tenth effective mating (me); however, many females mate at levels of me > 10, a zone we here call hyperpolyandry. We compared honey bee colony fitness at mating levels near and above this genetic diversity asymptote. We were interested in how hyperpolyandry affects...

Data from: Recalibrating timing behavior via expected covariance between temporal cues

Benjamin J. De Corte, Rebecca R. Della Valle & Matthew S. Matell
Individuals must predict future events to proactively guide their behavior. Predicting when events will occur is a critical component of these expectations. Temporal expectations are often generated based on individual cue-duration relationships. However, the durations associated with different environmental cues will often co-vary due to a common cause. We show that timing behavior may be calibrated based on this expected covariance, which we refer to as the 'common cause hypothesis'. In five experiments using rats,...

Data from: Artificial light at night confounds broad-scale habitat use by migrating birds

James D. McLaren, Jeffrey J. Buler, Tim Schreckengost, Jaclyn A. Smolinsky, Matthew Boone, E. Emiel Van Loon, Deanna K. Dawson & Eric L. Walters
With many of the world's migratory bird populations in alarming decline, broad-scale assessments of responses to migratory hazards may prove crucial to successful conservation efforts. Most birds migrate at night through increasingly light-polluted skies. Bright light sources can attract airborne migrants and lead to collisions with structures, but might also influence selection of migratory stopover habitat and thereby acquisition of food resources. We demonstrate, using multi-year weather radar measurements of nocturnal migrants across the northeastern...
