Diversity and development of the hemibacula of croaking geckos (Sphaerodactylidae: Aristelliger)

open access: yesJournal of Anatomy, EarlyView.
Geckos in the genus Aristelliger exhibit enigmatic mineralized elements in their hemipenes, called hemibacula. We examined hemibacula of every species of Aristelliger using μCT, clearing and staining, and histology. We found hemibacula exhibit lineage‐specific morphology, isometric growth after sexual maturity, and are composed of mineralized ...

Long lifespan and substantial biomass production support stable high biomass of Ascophyllum nodosum under interannual climate fluctuations in Greenland

open access: yesJournal of Phycology, EarlyView.
Abstract The brown macroalga Ascophyllum nodosum is a foundation species on intertidal rocky shores, where its perennial canopy and high productivity support key ecological functions. However, its population dynamics near the northern edge, where low temperatures and sea ice may challenge stability, are largely unknown.

Physiological and Behavioural Strategies of Bats From Arid Environments

open access: yesMammal Review, EarlyView.
Deserts are characterized by high ambient temperatures, intense solar radiation and low water availability. Desert bats are smaller, have lower energy expenditures, lower water losses, higher wing aspect ratios and lower wing loadings than bats living in mesic environments.

First At‐Sea Identifications of Ginkgo‐Toothed Beaked Whale (Mesoplodon ginkgodens): Acoustics, Genetics, and Biological Observations Off Baja California, México

open access: yesMarine Mammal Science, EarlyView.
ABSTRACT In 2024, an expedition was conducted off northwestern Baja California, México, to find and identify the beaked whale species that produced the BW43 echolocation pulse previously recorded in this area and elsewhere in the North Pacific. There were five Mesoplodon sightings and 21 BW43 acoustic detections on both a towed array and drifting pole ...

Aquilaria sinensis MYB‐Like Transcription Factor AsMYB1 Promotes 2‐(2‐Phenylethyl)Chromone Biosynthesis Through Interacting With 14‐3‐3 Family Protein AsGRF1

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT 2‐(2‐Phenylethyl)chromones (PECs) are the primary constituents of agarwood, a valuable aromatic resin widely used in traditional oriental medicine and incense production, exhibiting diverse pharmacological activities. While we have previously reported a polyketide synthase (AsPECPS) playing a crucial role in the biosynthesis of PECs in ...
