Automatic Classification of Planetary Surfaces Using Autoencoders With Applications to Dunes in the North Polar Erg of Mars

open access: yesJournal of Geophysical Research: Machine Learning and Computation
The study of planetary surface processes has traditionally relied on the manual interpretation of spacecraft images. While manual image analysis methods are robust and well‐established, they become impractical when the volume of available data is large ...

Animating blossom: Time‐lapse to encourage plant awareness in the YouTube era

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Time‐lapse videos can effectively capture key traits of flower blossoms, such as color, 3D structure, and temporal changes, making them valuable complements to herbarium specimens and other botanical collections. Despite the abundance of such videos on YouTube, most provide no ecological and botanical insights.

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Botanic and heritage gardens as living laboratories in the age of the polycrisis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Cities face intertwined crises of climate, biodiversity loss and social disconnection. We show how botanic and heritage gardens can help address these challenges as living laboratories to generate place‐based evidence and public engagement.

28 years of vegetation change (1978 – 2006) in a calcareous coastal dune system

open access: yes, 2010
Changes in vegetation structure and composition over a 28 year period (1978–2006) following removal of human-induced disturbances, were examined in a calcareous coastal dune system in Point Nepean National Park (380 19’S, 1440 41’E) in south-eastern ...

Experimental data of flow and turbulence properties above tidal dunes

open access: yes
A large-scale, high-resolution flume experiments were conducted under a representative bidirectional currents in a large recirculating flume to investigate the time-averaged flow and turbulence properties over two-dimensional fixed tidal dunes.

Gene turnover in the common ancestor of all C4 grasses

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

Ashwagandha: Is It Safe? Part 2: A Preclinical Evidence Review

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT The preclinical evidence for the safety of ashwagandha (Withania somnifera (L.) Dunal, AS) is reviewed, and its preparations (extracts) and constituents, from the general toxicity in animal models to in vitro and cell culture studies, which may elucidate mechanisms of action and explain clinical case reports.
