Do species conservation assessments capture genetic diversity?

open access: yesGlobal Ecology and Conservation, 2014
The best known system for classifying threat status of species, the IUCN Red List, currently lacks explicit considerations of genetic diversity, and consequently may not account for potential adaptation of species to future environmental change.

Long Secondary Periods in Pulsating Red Giants: A Century of Investigation [PDF]

open access: yesarXiv, 2022
Red giants are unstable to radial pulsation. About a third of them also show a long secondary period, 5 to 10 times the pulsation period. The long secondary periods were recently ascribed to eclipses of the red giant by a low-mass dust-enshrouded companion. Long secondary periods have been known for over a century.

Pulsation and Mass Loss Across the HR Diagram: From OB stars to Cepheids to Red Supergiants [PDF]

open access: yes, 2013
Both pulsation and mass loss are commonly observed in stars and are important ingredients for understanding stellar evolution and structure, especially for massive stars. There is a growing body of evidence that pulsation can also drive and enhance mass loss in massive stars and that pulsation-driven mass loss is important for stellar evolution.

Global phylogenetic and functional structure of rodent assemblages

open access: yesEcography, EarlyView.
Exploring the global patterns of phylogenetic and functional structure of assemblages is key to describe the distribution of biodiversity on Earth and to predict how communities and ecosystem functioning may be affected by anthropogenic pressures. Rodent communities have been studied in this regard in the past, but previous work largely focused on ...

Moving towards better risk assessment for invertebrate conservation

open access: yesEcography, EarlyView.
Global change threatens a vast number of species with severe population declines or even extinction. The threat status of an organism is often designated based on geographic range, population size, or declines in either. However, invertebrates, which comprise the bulk of animal diversity, are conspicuously absent from global frameworks that assess ...
