Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Pitting damage levels estimation for planetary gear sets based on model simulation and grey relational analysis [PDF]

open access: yes, 2011
The planetary gearbox is a critical mechanism in helicopter transmission systems. Tooth failures in planetary gear sets will cause great risk to helicopter operations.

Not Earth-like yet Temperate? More Generic Climate Feedback Configurations Still Allow Temperate Climates in Habitable Zone Exo-Earth Candidates

open access: yesThe Planetary Science Journal
Earth’s climate is influenced by over a dozen types of feedback, but only three dominate its long-term climate behavior. Models of the exoplanet habitable zone (HZ) assume that this is similar for other Earth-like planets.

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

Coupled Photochemical–Climate Modeling of Plausible Tenuous Outgassed Atmospheres on the TRAPPIST-1 Planets

open access: yesThe Planetary Science Journal
Available JWST observations of the TRAPPIST-1 system have suggested that several of the planets are likely airless, or possess a very tenuous atmosphere.

Energy Balance Models and Planetary Dynamics [PDF]

open access: yes, 2012
We know that planetary dynamics can have a significant affect on the climate of planets. Planetary dynamics dominate the glacial-interglacial periods on Earth, leaving a significant imprint on the geological record.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

open access: yesThe Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

The Climates and Thermal Emission Spectra of Prime Nearby Temperate Rocky Exoplanet Targets

open access: yesThe Astrophysical Journal
Over the course of the past decade, advances in radial velocity and transit techniques have enabled the detection of rocky exoplanets in the habitable zones of nearby stars.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...
