Bark characteristics affect epiphytic bryophyte cover across tree species

Devan Becker, Alistair Dobson & Kristen Klitgaard
Forest tree communities are shifting as a result of changes in regional climate and human management, which has cascading effects on other members of the community such as epiphytic bryophytes. Epiphytic bryophytes play important roles in ecosystem function, and their distribution is highly dependent on the characteristics of their substrate. To see how epiphytic substrate characteristics affect bryophyte abundance, we measured bark thickness, pH, and water holding capacity as it varied with bryophyte coverage on...

Effects of volatile compounds in California bay trees (Umbellularia californica) on vegetation growth and insect herbivory

Ashley Adornato, Hannah Gerber, Sarah Haas & Jennifer Perez
Secondary metabolites are volatile compounds produced by plants that can be used as defense mechanisms for reducing stressors such as herbivory and competition. Leaves, roots, and stems of California bay trees (Umbellularia californica) get their notable aroma from secondary metabolites called monoterpenes, which are allelopathic constituents in many other plants, such as eucalyptus. In this study, we investigated the potential allelopathic and anti-herbivory effects of California bay trees by examining their understory composition, germination rates...

The impact of shallow landslides on primary productivity

Addison Eftekhari, Carly Lam, Francesca Penny & Ian Silberstein
Shallow landslides provide us with a closer look at succession in response to disturbances and their long-term impact on a landscape. Shallow landslides are commonly found in low hills of coastal California, and while research has been conducted on the impacts to human infrastructure and habitation, effects on plant communities and subsequent succession has not been well researched. This study looked at the effect of shallow landslides on vegetation in the grasslands of UC Santa...

Long-term changes in composition of old-growth mixed evergreen forests in Mendocino County

, Charlie Schiebl, Gabriel Perez & John Salib
Abiotic factors have caused changes in old-growth California forests. These changes may be indicators of environmental stressors such as decreases in precipitation, increases in temperature, and changes in historic fire regimes. We aim to examine these changes by doing a 40-year follow-up study on Ashley Boren’s 1981 undergraduate thesis, conducted at Angelo Coast Reserve in Mendocino County, California. The purpose of this study is to examine whether or not the predictions made in 1981 would...

Herbivory defense and growth tradeoffs along a moisture gradient in Lupinus latifolius var. columbianus

Lilly Boiton, James Powers & Jordan Waits
Hypotheses such as the plant stress hypothesis, apparency theory, and the resource availability hypothesis provide contrasting predictions to how plants respond to abiotic stress and their interactions with herbivores. In this paper we examined the effects of a water availability gradient on the morphological characteristics and herbivory of Lupinus latifolius var. columbianus. We measured the abundance of the leaf beetle, Galeruca rudis, and Aphididae as well as the amount of leaf herbivory damage on lupine...

Factors affecting woodrat abundance over 70 years

Wolfgang Abad, Jose Morales-Doo, Carly Pomeroy & Adrienne Ung
Woodrats are ecosystem engineers that can increase biodiversity by physically changing the environment. In doing so, they alter landscapes and increase the number of microhabitats for other organisms. In order to better understand woodrats’ role in their ecosystem, we surveyed big-eared woodrat (Neotoma macrotis) houses in Hastings Natural History Reservation located in Monterey County, California. For each house, we determined its usability and measured its size. We found a 26 percent increase in population density...

Measurements from the Fire Influence on Regional and Global Environments Experiment (FIREX) Fire Lab Mini Chamber Experiment

Christopher Cappa, Christopher Lim, David Hagan & Jesse Kroll
All experiments were conducted during the Fire Influence on Regional to Global Environments Experiment (FIREX) lab study, which took place at the Missoula Fire Sciences Lab in Missoula, MT, USA during November, 2016. Experiments focused on refining our understanding of emissions and short timescale processing. The focus was on measuring fuels or combustion conditions that are characteristic of the western U.S. that may be under-sampled by the fire research community. Numerous types of biomass were...

Data from: Attacks on genetic privacy via uploads to genealogical databases

Doc Edge & Graham Coop
Direct-to-consumer (DTC) genetics services are increasingly popular for genetic genealogy, with tens of millions of customers as of 2019. Several DTC genealogy services allow users to upload their own genetic datasets in order to search for genetic relatives. The statement that a user's uploaded genome shares one or more segments in common with that of a target person in the database---that is, that the two genomes share one or more regions identical by state (IBS)---reveals...

Data from: Evolution of sexually dimorphic pheromone profiles coincides with increased number of male-specific chemosensory organs in Drosophila prolongata

Yige Luo, Yuewei Zhang, Jean-Pierre Farine, Jean-François Ferveur, Santiago Ramírez & Artyom Kopp
Binary communication systems that involve sex-specific signaling and sex-specific signal perception play a key role in sexual selection and in the evolution of sexually dimorphic traits. The driving forces and genetic changes underlying such traits can be investigated in systems where sex-specific signaling and perception have emerged recently and show evidence of potential coevolution. A promising model is found in Drosophila prolongata, which exhibits a species-specific increase in the number of male chemosensory bristles. We...
