No link between population isolation and speciation rate in squamate reptiles

Sonal Singhal, Guarino Colli, Maggie Grundler, Gabriel Costa, Ivan Prates & Daniel Rabosky
Rates of species formation vary widely across the tree of life and contribute to massive disparities in species richness among clades. This variation can emerge from differences in metapopulation-level processes that affect the rates at which lineages diverge, persist, and evolve reproductive barriers and ecological differentiation. For example, populations that evolve reproductive barriers quickly should form new species at faster rates than populations that acquire reproductive barriers more slowly. This expectation implicitly links microevolutionary processes...

Disease or drought: Environmental fluctuations release zebra from a potential pathogen-triggered ecological trap

Yen-Hua Huang, Hendrina Joel, Martina Küsters, Zoe Barandongo, Claudine Cloete, Axel Hartmann, Pauline Kamath, Werner Kilian, John Mfune, Gabriel Shatumbu, Royi Zidon, Wayne Getz & Wendy Turner
When a transmission hotspot for an environmentally persistent pathogen establishes in otherwise high-quality habitat, the disease may exert a strong impact on a host population. However, fluctuating environmental conditions lead to heterogeneity in habitat quality and animal habitat preference, which may interrupt the overlap between selected and risky habitats. We evaluated spatiotemporal patterns in anthrax mortalities in a plains zebra (Equus quagga) population in Etosha National Park, Namibia, incorporating remote-sensing and host telemetry data. A...

The Ant Who Cried Wolf? Short-Term Repeated Exposure to Alarm Pheromone Reduces Behavioral Response in Argentine Ants

Brian Whyte, Jessica J. Maccaro & Neil D. Tsutsui
In this study we test whether Argentine ants (Linepithema humile) progressively reduce their response to a salient stimulus (alarm pheromone) with increased exposure over time. First, we used a two-chamber olfactometer to demonstrate three focal behaviors of Argentine ants that indicate an alarmed state in response to conspecific alarm pheromone and pure synthetic iridomyrmecin (a dominant component of L. humile alarm pheromone). We then measured how these behaviors changed after repeated exposure to conspecific alarm...

Data from: Jump takeoff in a small jumping spider

Erin Brandt, Yoshan Sasiharan, Damian Elias & Natasha Mhatre
Jumping in animals presents an interesting locomotory strategy as it requires the generation of large forces and accurate timing. Jumping in arachnids is further complicated by their semi-hydraulic locomotion system. Among arachnids, jumping spiders (Family Salticidae) are agile and dexterous jumpers. However, less is known about jumping in small salticid species. Here we used Habronattus conjunctus, a small jumping spider (body length ~4.5 mm) to examine its jumping performance and compare it to that of...

A machine learning approach to integrating genetic and ecological data in tsetse flies (Glossina pallidipes) for spatially explicit vector control planning

Anusha Bishop, Giuseppe Amatulli, Chaz Hyseni, Evlyn Pless, Rosemary Bateta, Winnie Okeyo, Paul Mireji, Sylvance Okoth, Imna Malele, Grace Murilla, Serap Aksoy & Norah Saarman
Introduction - Control of vector populations is an effective strategy for addressing vector-borne disease transmission. Effective vector control requires knowledge of habitat use and connectivity. Our goal was to improve this knowledge for the tsetse species Glossina pallidipes, a vector of animal African trypanosomiasis, which is a wasting disease in livestock and represents a serious socioeconomic burden across sub-Saharan Africa. Methods and Results - We used random forest regression to: (i) Build and integrate models...

Toxic Y chromosome: increased repeat expression and age-associated heterochromatin loss in male Drosophila with a young Y chromosome

Alison Nguyen & Doris Bachtrog
Sex-specific differences in lifespan are prevalent across the tree of life and influenced by heteromorphic sex chromosomes. In species with XY sex chromosomes, females often outlive males. Males and females can differ in their overall repeat content due to the repetitive Y chromosome, and repeats on the Y might lower survival of the heterogametic sex (toxic Y effect). Here, we take advantage of the well-assembled young Y chromosome of Drosophila miranda to study the sex-specific...

Live imaging and biophysical modeling support a button-based mechanism of somatic homolog pairing in Drosophila

Myron Barber Child, Jack R Bateman, Amir Jahangiri, Armando Reimer, Nicholas C Lammers, Nica Sabouni, Diego Villamarin, Grace C McKenzie-Smith, Justine E Johnson, Daniel Jost & Hernan G Garcia
3D eukaryotic genome organization provides the structural basis for gene regulation. In Drosophila melanogaster, genome folding is characterized by somatic homolog pairing, where homologous chromosomes are intimately paired from end to end; however, how homologs identify one another and pair has remained mysterious. Recently, this process has been proposed to be driven by specifically interacting 'buttons' encoded along chromosomes. Here, we turned this hypothesis into a quantitative biophysical model to demonstrate that a button-based mechanism...

Intermediate fire severity diversity promotes richness of forest carnivores in California

Brett Furnas, Benjamin Goldstein & Peter Figura
Aim: Fire can strongly influence ecosystem function, and human activities are disrupting fire activity at the global scale. Ecological theory and a growing body of literature suggest that a mixed severity fire regime promotes biodiversity in western North America. Some researchers advocate the use of pyrodiversity (i.e., heterogeneity in aspects of the fire regime such as time since fire or severity) as a conservation index to be maximized. Others caution against this approach arguing that...

nIRCat characterization and acute brain slice imaging

Jackson Del Bonis-O'Donnell, Sarah Yang & Markita Landry
Dopamine neuromodulation of neural synapses is a process implicated in a number of critical brain functions and diseases. Development of protocols to visualize this dynamic process is essential to understanding how dopamine modulates neurochemical brain function. We have developed a non-genetically encoded, near infrared (nIR) catecholamine nanosensor (nIRCat) capable of identifying ~2 µm dopamine release hotspots in the dorsal striatal brain slices. This platform is readily introduced into both genetically tractable and intractable organisms and...

Diet sensitivity in field crickets

Lisa Treidel, Rebecca Clark, Melissa Lopez & Caroline Williams
Animals adjust resource acquisition throughout life to meet changing physiological demands of growth, reproduction, activity, and somatic maintenance. Wing-polymorphic crickets invest in either dispersal or reproduction during early adulthood, providing a system in which to determine how variation in physiological demands, determined by sex and life history strategy, impact nutritional targets, plus the consequences of nutritionally imbalanced diets across life stages. We hypothesized that high demands of biosynthesis (especially oogenesis in females) drive elevated resource...

Data from: Gene expression plasticity and desert adaptation in house mice

Noelle Bittner, Katya Mack & Michael Nachman
Understanding how organisms adapt to new environments is a key problem in evolution, yet it remains unclear whether phenotypic plasticity generally facilitates or hinders this process. Here we studied evolved and plastic responses to water-stress in lab-born descendants of wild house mice (Mus musculus domesticus) collected from desert and non-desert environments and measured gene expression and organismal phenotypes under control and water-stressed conditions. After many generations in the lab, desert mice consumed significantly less water...

Multi-year time shift study of bacteria and phage dynamics in the phyllosphere

Emily Dewald-Wang, Nicole Parr, Katie Tiley, Alina Lee & Britt Koskella
Coevolutionary dynamics shape diversity within and among populations but are difficult to study directly. Time shift experiments, where populations of species A from one point in time are experimentally challenged against populations of species B from past, contemporary, and/or future time points, and vice versa, are a particularly powerful tool to measure coevolution. This approach has been primarily applied to study host-parasite interactions and proven useful in directly measuring coevolutionary change and distinguishing among coevolutionary...

Data from: A test for rate-coupling of trophic and cranial evolutionary dynamics in New World bats

Jeff Shi, Erin Westeen & Daniel Rabosky
Data supporting article Shi et al. 2021, Evolution: https://doi.org/10.1111/evo.14188 Morphological evolution is often assumed to be causally related to underlying patterns of ecological trait evolution. However, few studies have directly tested whether evolutionary dynamics of and major shifts in ecological resource use are coupled with morphological shifts that may facilitate trophic innovation. Using diet and multivariate cranial (microCT) data, we tested whether rates of trophic and cranial evolution are coupled in the radiation of New...

MHD field line tracing for 2017 Sept ICME study

Shaosui Xu
Many aspects of the Sun-Mars interaction have been investigated during solar transient events with measurements from multiple spacecrafts and also simulation efforts. Limited discussion has been paid to magnetic topology response to disturbed upstream conditions. The implications of topology changes include, but are not limited to, the pattern of energetic particle precipitation into the Martian atmosphere and the impact on cold ion escape during solar transient events as low-energy ion escape is dependent on magnetic...
