Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Ultraviolet and Chromospheric Activity and Habitability of M Stars

open access: yesThe Astrophysical Journal
M-type stars are crucial for stellar activity studies because they cover two types of magnetic dynamos and are particularly intriguing for habitability studies due to their abundance and long lifespans during the main-sequence stage.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

When the Remedy Is Worse Than the Illness: Carbon Performance and Growth Opportunities Under the EU ETS

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This paper examines how the European Union Emissions Trading System allowance prices reshape the link between corporate environmental performance (CEP) and firms' growth expectations, measured by Tobin's Q. Using a panel of 1370 listed firms across 15 European countries from 2005 to 2024 and high‐dimensional fixed‐effects models, we first ...

Exomoons and Exorings with the Habitable Worlds Observatory. II. Finding “Endor” with Lunar Eclipses

open access: yesThe Astronomical Journal
Giant planets in the habitable zone may host exomoons with conditions conducive to life. In this paper, we describe a method by which the Habitable Worlds Observatory (HWO) could detect such moons: broadband reflected-light lunar eclipses (e.g., the moon
