Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Seasonal variation in wind speed and oceanic salt spray favors delayed reproduction in coastal yellow monkeyflowers

American Journal of Botany, EarlyView.
Abstract Premise The optimal timing of reproduction depends on the relative risk and benefit of continued growth. These risks and benefits depend on the local environment, which varies seasonally. While temperature and water availability are well‐studied selective agents on reproductive timing, less is known about other seasonally variable factors ...

Allergic Rhinitis Amplifies Asthma Risk in Patients With Chronic Rhinosinusitis: A Large‐Scale Retrospective Cohort Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) and allergic rhinitis (AR) are two highly prevalent airway diseases in the United States. While the coexistence of CRS and asthma is well recognized, less is known about the development of new‐onset asthma in CRS, particularly in the context of comorbid AR. This study assessed the impact of CRS and AR on

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

The 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 ...

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

HSP90-mediated stress resilience in male gametophyte of Arabidopsis thaliana

Plant Stress
Despite the accumulation of protective heat shock proteins (HSPs) during the male gametophyte development, pollen grains are highly sensitive to elevated temperatures. We performed transcriptomic analysis of five pollen developmental stages isolated from

Bite force estimates and morphological correlations of jaw muscles in parrots

The Anatomical Record, EarlyView.
Abstract Parrots (Order: Psittaciformes) are renowned for their high bite force (BF) and morphological correlates thereof, including a highly mobile skull and two unique mandibular adductor muscles—m. pseudomasseter and m. ethmomandibularis, with the former being hypothesized to increase force output.

Do consumers and healthcare professionals report the same adverse event differently? A paired analysis of duplicate vaccine safety reports in Norway

British Journal of Clinical Pharmacology, EarlyView.
Aim This study aimed to compare how Norwegian healthcare professionals (HCPs) and consumers reported the same adverse event (AE) following immunization with vaccines against COVID‐19 during the COVID‐19 pandemic. Specifically, we aimed to compare the extent to which HCPs and consumers reported information relevant for assessing the causal relationship ...
