Phylogenomic analyses in Phrymaceae reveal extensive gene tree discordance in relationships among major clades

Diego F. Morales-Briones, Nan Lin, Eileen Huang, Dena Grossenbacher, James Sobel, Caroline Gilmore, David Tank & Ya Yang
• Premise of the study: Phylogenomic datasets using genomes and transcriptomes provide rich opportunities beyond resolving bifurcating phylogenetic relationships. Monkeyflower (Phrymaceae) is a model system for evolutionary ecology. However, it lacks a well-supported phylogeny for a stable taxonomy and for macroevolutionary comparisons. • Methods: We sampled 24 genomes and transcriptomes in Phrymaceae and closely related families, including eight newly sequenced transcriptomes. We reconstructed the phylogeny using IQ-TREE and ASTRAL, evaluated gene tree discordance using PhyParts,...

Recruiting Engagement through Readings + Media in Architectural Technology Education

Carmen Trudell
The Architectural Technology Fundamentals course has always included reading assignments – usually chapters from a textbook loaded with technical information, data, and a bit of history. In 2020, underpinned by historic shifts in expectations for architectural education, we took a critical look at our teaching and targeted the reading assignment as an opportunity to teach with equity and about equity. The readings have consistently ranked as the least effective learning mode, falling well behind the...

Thinking Outside the Building

Sandy Stannard
In response to the health crisis, they set up schools on abandoned ferries; classes were held on rooftops and in nearby forests.1 The above quote is not a description of contemporary educational spaces in response to the current COVID-19 pandemic. Rather, this is a description of outdoor learning environments established in response to the early 20th century tuberculosis crisis. At the time, there were 65 such outdoor classrooms established as alternative teaching and learning environments.2...

Native annual forb and vegetation data for ten paired grazed and ungrazed prairies in coastal California grasslands at two time periods 15 years apart

Josephine Lesage, Karen Holl & Grey Hayes
Livestock grazing is often used as a land management tool to maximize vegetation diversity in grassland ecosystems worldwide. Prior research has shown that cattle grazing benefits native annual forb species in California’s coastal prairies, but drought and increasing aridity may alter this relationship. In 2016 and 2017, we resurveyed the vegetation structure, native annual forb cover, and native annual forb richness in ten grazed and ungrazed prairies that were originally measured in 2000 and 2001...

Evolutionary convergence on hummingbird pollination in Neotropical Costus provide insight into the causes of pollinator shifts

Kathleen Kay & Dena Grossenbacher
1. The evolution of hummingbird pollination is common across angiosperm lineages throughout the Americas, presenting an opportunity to examine convergence in both traits and environments to better understand how complex phenotypes arise. We examine multiple independent shifts from bee to hummingbird pollination in the Neotropical spiral gingers (Costus) and use our data to address several common explanations for the prevalence of bee to bird pollination transitions. 2. We use floral traits of species with observed...

The broken-wing display across birds and the conditions for its evolution

Clinton Francis, Léna De Framond & Henrik Brumm
The broken-wing display is a well-known and conspicuous deceptive signal used to protect birds’ broods against diurnal terrestrial predators. Although commonly associated with shorebirds, it remains unknown how common the behaviour is across birds and what forces are associated with the evolution of the display. Here, we use the broken-wing display as a paradigmatic example to study the evolution of a behaviour across Aves. We show that the display is widespread: it has been described...

Experimentally broadcast ocean surf and river noise alters birdsong structure

Clinton Francis, Veronica Reed, Cory Toth, Ryan Wardle, Dylan Gomes & Jesse Barber
Anthropogenic noise and its effects on acoustic communication have received considerable attention in recent decades. Yet, the natural acoustic environment’s influence on communication and its role in shaping acoustic signals remains unclear. Using landscape-level playbacks of ocean surf and river noise in coastal and riparian habitat, respectively, we investigated how water-generated noise influences spectral and temporal song characteristics in six songbird species. We recorded individuals defending territories across 37 sites, with each site representing one...

Advanced Tall Buildings Systems Integration

Thomas Fowler IV & Kevin Dong
The 2020 Skyscraper Collaboratory was a partnership between Cal Poly, San Luis Obispo, California University’s interdisciplinary design studio (architecture and structural engineering) and the design / structural engineering partners from Skidmore, Owings & Merrill’s (SOM) San Francisco, California’s Office, an internationally acclaimed firm that specializes in skyscrapers. The academic design studio was set up to mirror the advanced collaborative practice model of the partner firm, by balancing the nine teams (34 students total) with architecture...

Karuk ecological fire management practices promote elk habitat in Northern California

Thomas Connor, Emilio Tripp, William Tripp, B. J. Saxon, Jessica Camarena, Asa Donahue, Daniel Sarna, Luke Macaulay, Tim Bean, Adam Hanbury-Brown & Justin Brashares
After a century of fire suppression and accumulating fuel loads in North American forests, prescribed burns are increasingly used to prevent conditions leading to catastrophic megafire. There is widespread evidence that prescribed fire was used by Indigenous communities to manage natural and cultural resources tribes for thousands of years. Wildlife habitat is an example of an ecological response that was actively managed with prescribed burns by Indigenous American peoples and is an important factor in...

Data from: Global plant ecology of tropical ultramafic ecosystems

Felipe, Ricardo García, José Luis Gómez Hechavarría, Aretha Franklin Guimarães, Ernesto Medina, Adrian L.D. Paul, Nishanta Rajakaruna, Carla Restrepo, Stefan Siebert, Eduardo Van Den Berg, Antony Van Der Ent & Grisel Velasquez
This is a compiled geospatial dataset in ESRI polygon shapefile format of ultramafic soils of the neotropics showing the location of ultramafic soils in Guatemala, Cuba, Dominican Republic, Puerto Rico, Costa Rica, Colombia, Argentina, Chile, Venezuela, Ecuador, Brazil, Suriname, French Guiana, and Bolivia. The data are derived from seven geospatial datasets. Original datasets were subset to include only ultramafic areas, datasets were assigned a common projection (WGS84), attribute tables were reconciled to a common set...
