Life history and environment predict variation in testosterone across vertebrates

Jerry Husak, Matthew Fuxjager, Michele A. Johnson, Maren Vitousek, Jeremy Donald, Clinton David Francis, Wolfgang Goymann, Michaela Hau, Bonnie Kircher, Rosemary Knapp, Lynn B. Martin, Eliot Miller, Laura Schoenle & Tony Williams
Endocrine systems act as key intermediaries between organisms and their environments. This interaction leads to high variability in hormone levels, but we know little about the ecological factors that influence this variation within and across major vertebrate groups. We study this topic by assessing how various social and environmental dynamics influence testosterone levels across the entire vertebrate tree of life. Our analyses show that breeding season length and mating system are the strongest predictors of...

Closely related tree species support distinct communities of seed-associated fungi in a lowland tropical forest

Paul-Camilo Zalamea, Carolina Sarmiento, Elizabeth Arnold, Adam Davis, Astrid Ferrer & James Dalling
Previous theoretical work has highlighted the potential for natural enemies to mediate the coexistence of species with similar life-histories via density-dependent effects on survivorship. For plant pathogens to play this role, they must differ in their ability to infect or induce disease in different host plant species. In tropical forests characterized by high diversity, these effects must extend to phylogenetically closely related species pairs. Mortality at the seed and seedling stage strongly influences the abundance...

The moment of tooth: rate, fate, and pattern of Pacific lingcod dentition revealed by pulse-chase

Emily Carr, Adam Summers & Karly Cohen
Tooth replacement rates of polyphyodont cartilaginous and bony fishes are hard to determine because of lack of obvious patterning, and maintaining specimens long enough to observe replacement. Pulse-chase is a fluorescent technique that differentially colours developing mineralized tissue. We present in-situ tooth replacement rate and position data for the oral and pharyngeal detentions of Ophiodon elongatus (Pacific lingcod). We assessed over 10,000 teeth, in 20 fish, and found a daily replacement rate of about two...

Data For: The developing bird pelvis passes through ancestral Archosaurian and Dinosaurian conditions

Christopher Griffin, João Botelho, Michael Hanson, Matteo Fabbri, Daniel Smith-Paredes, Ryan Carney, Mark Norell, Shiro Egawa, Stephen Gatesy, Timothy Rowe, Ruth Elsey, Sterling Nesbitt & Bhart-Anjan Bhullar
Living birds (Aves) have bodies dramatically modified from the ancestral reptilian condition. The avian pelvis in particular experienced dramatic changes during the transition from early archosaurs to living birds. This stepwise transformation is well documented by an excellent fossil record; however, the ontogenetic alterations that underly it are less well-understood. We used embryological imaging techniques to examine the morphogenesis of avian pelvic tissues in three dimensions, allowing direct comparison with the fossil record. Many ancestral...

Light pollution affects West Nile virus exposure risk across Florida

Meredith Kernbach
Emerging infectious diseases (EIDs) present global health threats, and their emergences are often linked to anthropogenic change. Artificial light at night (ALAN) is one form of anthropogenic change that spans beyond urban boundaries and may be relevant to EIDs through its influence on behavior and physiology of hosts and/or vectors. Although West Nile virus (WNV) emergence has been described as peri-urban, we hypothesized that exposure risk could also be influenced by ALAN in particular, which...

Examining Variation in Compliance to a New School Counselor Policy by School and School Counseling Program Variables

Supplementary information provided with Murray et al.: Discovery of an Antarctic ascidian-associated uncultivated Verrucomicrobia with antimelanoma palmerolide biosynthetic potential

Alison E Murray, Chien-Chi Lo, Hajnalka E Daligault, Nicole E Avalon, Robert W Read, Karen W Davenport, Mary L Higham, Yuliya Kunde, Armand EK Dichosa, Bill J Baker & Patrick SG Chain
The Antarctic marine ecosystem harbors a wealth of biological and chemical innovation that has risen in concert over millennia since the isolation of the continent and formation of the Antarctic circumpolar current. Scientific inquiry into the novelty of marine natural products produced by Antarctic benthic invertebrates led to the discovery of a bioactive macrolide, palmerolide A, that has specific activity against melanoma and holds considerable promise as an anticancer therapeutic. While this compound was isolated...

Repeated genetic and adaptive phenotypic divergence across tidal elevation in a foundation plant species

Robyn Zerebecki, Erik E Sotka, Torrance C Hanley, Katherine L. Bell, Catherine Gehring, Chris C. Nice, Christina L. Richards & A Randall Hughes
Microgeographic genetic divergence can create fine-scale trait variation. When such divergence occurs within foundation species, then it might impact community structure and ecosystem function, and cause other cascading ecological effects. We tested for parallel microgeographic trait and genetic divergence in Spartina alterniflora , a foundation species that dominates salt marshes of the US Atlantic and Gulf coasts. Spartina is characterized by tall-form (1-2m) plants at lower tidal elevations and short-form (<0.5m) plants at higher tidal...

Long-term change in the parasite burden of shore crabs (Hemigrapsus oregonensis and H. nudus) on the northwestern Pacific coast of North America

Jessica Quinn, Sarah Lee, Duncan Greeley, Alyssa Gehman, Armand Kuris & Chelsea Wood
The abundances of free-living species have changed dramatically in recent decades, but little is known about change in the abundance of parasitic species. We investigated whether populations of several parasites have shifted over time in two shore crab hosts, Hemigrapsus oregonensis and H. nudus, by comparing the prevalence and abundance of three parasite taxa in a historical dataset (1969–1970) to contemporary parasite abundance (2018–2020) for hosts collected from 11 intertidal sites located from Oregon, USA...

Collaborative Research: Project Incubation -- NJIT-CAREs: New Jersey Institute of Technology Campus Alignment Review of Ethics

David Kidd
For this Project Incubation award, we propose a one-year project at New Jersey Institute of Technology
(NJIT) to pilot mixed-methodologies developed by the National Ethics Project (NEP), with the goal of
establishing a baseline for writing a collaborative Institutional Transformation proposal to be submitted in
the following funding cycle. This Incubation Project constitutes the next incremental step in a series of
projects intended to benefit a broad range of institutions in auditing or transforming approaches to ER2.
