Fractional crystallization of a Martian magma ocean and formation of a thermochemical boundary layer at the base of the mantle

Garrett Zeff
BurnMan and pMELTS outputs for simulations of fractionally crystallizing magma oceans on Mars.

Data for Drought-Net rainfall shelters did not cause non-drought effects on photosynthesis for California central coast plants.

Michael Loik
Rainfall interception shelters are frequently used to study the ecological consequences of drought. One common shelter design employs V-shaped plastic troughs spaced on a supporting frame to intercept rainfall. Shading, reflection, and infrared radiation may alter the radiative environment under shelters in ways independent of their intended effect on soil moisture. We measured microclimate and several photosynthetic variables for watered potted plants under rain-out shelters and in open-air, unsheltered plots. We tested whether the shelter...

Utilizing field collected insects for next generation sequencing: effects of sampling, storage, and DNA extraction methods

Kimberly Ballare, Nathaniel Pope, Antonio Castilla, Sarah Cusser, Richard Metz & Shalene Jha
DNA sequencing technologies continue to advance the biological sciences, expanding opportunities for genomic studies of non-model organisms for basic and applied questions. Despite these opportunities, many next-generation sequencing protocols have been developed assuming a substantial quantity of high molecular weight DNA (>100 ng), which can be difficult to obtain for many study systems. In particular, the ability to sequence field-collected specimens that exhibit varying levels of DNA degradation remains largely unexplored. In this study we...

Sperm morphology and count vary with fine-scale changes in local density in a wild lizard population

Matthew C Kustra, Ariel F Kahrl, Aaron M Reedy, Daniel A Warner & Robert M Cox
Given that sperm production can be costly, theory predicts that males should optimally adjust the quantity and/or quality of their sperm in response to their social environment to maximize their paternity success. Although experiments demonstrate that males can alter their ejaculates in response to manipulations of the social environment and studies show that ejaculate traits covary with social environment across populations, it is unknown whether individual variation in sperm traits corresponds to natural variation found...

Interspecific and intra-shell stable isotope variation among the Red Sea giant clams

Daniel Killam, Ryan Thomas, Matthew Clapham & Tariq Al-Najjar
The Gulf of Aqaba is home to three giant clam species with differing ecological niches and levels of photosymbiotic activity. Giant clams grow a two-layered shell where the outer layer is precipitated in close association with photosymbiont-bearing siphonal mantle, and the inner layer is grown in association with the light-starved inner mantle. We collected 38 shells of the three species (the cosmopolitan Tridacna maxima and T. squamosa, as well as the rare endemic T. squamosina),...

Understanding forest dynamics by integrating age and environmental change

Kai Zhu
How much carbon a forest ecosystem can sequester is determined by both post-disturbance regrowth and environmentally modified growth. Disturbance causes sharp declines in the short term and is followed by regrowth in the long term. Environmental change may alter carbon accumulation through increasing CO2, nitrogen deposition, and climate change. Regrowth and modified growth occur simultaneously, yet they are usually studied separately and assessed using an additive approach. Alternatively, an interactive approach using hierarchical models can...

A sample of Saturn interior density profiles derived with MCMC and gravity-based likelihood.

Naor Movshovitz, Jonathan Fortney, Chris Mankovich, Daniel Thorngren & Ravit Helled
We ran a Markov-Chain Monte Carlo algorithm to derive the posterior distribution of density profiles for Saturn, where the likelihood function was a chi-squared distributed distance of each curve's gravity coefficients from the values reported for that planet by the Cassini radio science team (Iess et al., 2019). The result is a large sample of interior profiles of Saturn consistent with observation and minimally constrained by model assumptions. This sample is archived here in sufficiently...
