PtoHY5 integrates photoperiodic signals with the ABA pathway to coordinate growth cessation and dormancy in Populus

open access: yesJournal of Integrative Plant Biology, EarlyView.
In Populus, short days deactivate the growth‐promoting protein PtoHY5, turning off a growth accelerator and activating an abscisic acid‐driven brake. This directly couples growth cessation with dormancy, underscoring the role of abscisic acid in synchronizing these transitions for winter survival.

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

open access: yesJournal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

When indemnity insurance fails: Parametric coverage under binding budget and risk constraints

open access: yesJournal of Risk and Insurance, EarlyView.
Abstract In high‐risk environments, traditional indemnity insurance is often unaffordable or ineffective, despite its well‐known optimality under expected utility. We compare excess‐of‐loss indemnity insurance with parametric insurance within a common mean‐variance framework, allowing for fixed costs, heterogeneous premium loadings, and binding budget ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

“A Person's God Should Look Like Them”: African Traditional Religions Among Black Queer Millennials and Gen Z Americans

open access: yesJournal for the Scientific Study of Religion, EarlyView.
ABSTRACT How are young Black Americans practicing spirituality contemporarily? Today younger generations of Black Americans are more likely than older Black Americans to identify as religiously unaffiliated or as practicing a non‐Christian faith. Drawing on 109 interviews with Black Millennial and Gen Z Americans, I examine how some of these younger ...

Phylogenetic Reconstruction of Lung Evolution in Extant Squamata

open access: yesJournal of Zoology, EarlyView.
The Squamata group exhibits remarkable diversity in lung structure. However, a comprehensive understanding of how this variation evolved within the clade is still lacking. To reconstruct the evolutionary history of lungs of living squamates, we conducted comparative phylogenetic analyses using categorized lung traits, such as lung type, respiratory ...
