Mucilage-binding to ground protects seeds of many plants from harvester ants: a functional investigation

Vincent Pan, Marshall McMunn, Richard Karban, Jake Goidell, Eric LoPresti & Marjorie Weber
The seeds of many plant species produce mucilage on their surfaces that when wetted and dried, firmly adheres seeds to surfaces and substrates. Previous studies have demonstrated that seed anchorage to the ground can reduce seed predation, though only a few species have thus far been tested. Here we investigated whether binding to the ground reduces seed removal by harvester ants (Pogonomyrmex subdentatus), an important granivore, for 53 species with mucilaginous seeds. We also explored...

Sex-specific speed-accuracy tradeoffs shape neural processing of acoustic signals in a grasshopper

Jan Clemens, Bernhard Ronacher & Michael Reichert
Speed-accuracy tradeoffs – being fast at the risk of being wrong – are fundamental to many decisions and natural selection is expected to resolve these tradeoffs according to the costs and benefits of behavior. We here test the prediction that females and males should integrate information from courtship signals differently because they experience different payoffs along the speed-accuracy continuum. We fitted a neural model of decision making (a drift-diffusion model of integration to threshold) to...

Data for: PickMe: sample selection for species tree reconstruction using coalescent weighted quartets

Joseph Rusinko, Yu Cai, Allison Doherty, Katherine Thompson, Julien Boutte, Mark Fishbein & Shannon Straub
After collecting large data sets of many genes for many species for phylogenomics studies, researchers may make ad hoc decisions about which genes or samples to include in a species tree reconstruction analysis based on various parameters, including the amount of missing data. Optimally, sampling would be maximized, but it can be difficult for empiricists to determine where to draw the line for sample inclusion when data sets are incomplete. Under the multispecies coalescent model,...

Data from: A generalist bird exhibits site-dependent resource selection

Samantha M. Cady, Craig A. Davis, Dwayne R. Elmore, Samuel D. Fuhlendorf, Cameron Duquette, Evan P. Tanner & Matthew J. Carroll
Quantifying resource selection (an organism’s disproportionate use of available resources) is essential to infer habitat requirements of a species, develop management recommendations, predict species responses to changing conditions, and improve our understanding of the processes that underlie ecological patterns. Because study sites, even within the same region, can differ in both the amount and the arrangement of cover types, our objective was to determine whether proximal sites can yield markedly different resource selection results for...

The Effectiveness of Check-In/Check-Out (CICO) Among High School Students

Hannuja Vijayan
This study reviews whether check-in/check-out intervention is effective at increasing on-task behavior among attention problem students in the high-school. Also, this study examines whether there is an effectiveness difference between utilizing and not utilizing CICO intervention among the attention problem students.

Information & Resource Sharing Study (July 2020)

Laureon Merrie, Jaimie Krems & Daniel Sznycer
Here we apply the principles of Hamilton's rule (rB>C) to explore the circumstances under which individuals decide to share with/help others at some cost to oneself. Specifically, we explore helping intentions.

Data from: Drivers of site fidelity in ungulates

Thomas Morrison, Jerod Merkel, J. Grant Hopcraft, Ellen Aikens, Jeffrey Beck, Randall Boone, Alyson Courtemanch, Samantha Dwinnell, Sue Fairbanks, Brad Griffith, Arthur Middleton, Kevin Monteith, Brendan Oates, Louise Riotte-Lambert, Hall Sawyer, Kurt Smith, Jared Stabach, Kaitlyn Taylor & Matthew Kauffman
While the tendency to return to previously visited locations – termed ‘site fidelity’ – is common in animals, the cause of this behaviour is not well understood. One hypothesis is that site fidelity is shaped by an animal’s environment, such that animals living in landscapes with predictable resources have stronger site fidelity. Site fidelity may also be conditional on the success of animals’ recent visits to that location, and it may become stronger with age...

Phenotypic and genomic diversification with isolation by environment along elevational gradients in a neotropical treefrog

Ricardo Medina, Ella Vázquez-Domínguez, Guinevere O.U. Wogan, Ke Bi, Flavia Termignoni-García, Manuel Hernando Bernal, Juan P. Jaramillo-Correa & Ian J. Wang
Understanding how geographic and environmental heterogeneity drive local patterns of genetic variation is a major goal of ecological genomics and a key question in evolutionary biology. The tropical Andes and inter-Andean valleys are shaped by markedly heterogeneous landscapes, where species experience strong selective processes. We examined genome-wide SNP data together with behavioral and ecological traits (mating calls and body size) known to contribute to genetic isolation in anurans in the emerald-eyed treefrog, Boana platanera, distributed...

Inhibitory control, exploration behaviour and manipulated ecological context are associated with foraging flexibility in the great tit

Jenny Coomes, Gabrielle Davidson, Michael Reichert, Ipek Kulahci, Camille Troisi & John Quinn
​​​​​Organisms are constantly under selection to respond effectively to diverse, sometimes rapid, changes in their environment, but not all individuals are equally plastic in their behaviour. Although cognitive processes and personality are expected to influence individual behavioural plasticity, the effects reported are highly inconsistent, which we hypothesise is because ecological context is usually not considered. We explored how one type of behavioural plasticity, foraging flexibility, was associated with inhibitory control (assayed using a detour-reaching task)...

Acute pseudo-landmarking and Constellation homologies: A generalized workflow to identify and track segmented structures in plant time series images

John Hodge
Assessing plant phenotypes throughout the lifecycle is integral to exploring the development, genetics, and evolution of morphology, and can be critical for agronomic and basic research studies. Although various automated or semi-automated phenomic approaches have been developed, it has been challenging to analyze differential growth because of difficulties in segmenting and annotating specific structures or positions in the plant body and maintaining their identities throughout time-series data. To address this gap, we have developed a...
