Giants in the cold: Morphological evidence for vascular heat retention in the viscera but not the skeletal muscle of the basking shark (Cetorhinus maximus)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fewer than 50 of the over 30,000 extant species of fishes have developed anatomical specializations facilitating endothermy in specific body regions. The plankton‐feeding basking shark (Cetorhinus maximus), traditionally classified as an ectotherm, was recently shown to have regionally endothermic traits such as centralized red muscle (RM ...

Auxin response and PIN‐mediated transport in chlorophyte algae

open access: yesJournal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Virtual brain endocasts of the palaeanodont Metacheiromys marshi and the neurosensory evolution of early Pholidotamorpha

open access: yesJournal of Anatomy, EarlyView.
We describe the endocranial anatomy of Metacheiromys marshi. Decrease in olfaction and eye movement control occurred through time in Pholidotamorpha and is likely linked to fossorial adaptations. The development of the orbital gyrus might be related to the evolution of myrmecophagy and the emergence of a protrusile tongue in early Pholidotamorpha ...

Earnings Trajectories Around Parenthood: Male Same‐Sex Couples in Denmark, the Netherlands and Sweden

open access: yesJournal of Marriage and Family, EarlyView.
ABSTRACT Objective This study examines earnings trajectories of male same‐sex couples around the time they become parents in Denmark, the Netherlands, and Sweden: three forerunners in advancing same‐sex couples' legal rights but with different family policy frameworks.

Sibling Complexity Across Childhood: A 16‐Year Follow‐up of the 1988 and 2000 Birth Cohorts in Finland

open access: yesJournal of Marriage and Family, EarlyView.
ABSTRACT Objective This study quantifies sibling experiences across childhood by birth cohort and maternal education. Background As family structures evolve, sibling complexity—the presence of half and stepsiblings—is becoming more common. Yet, little is known about how sibling constellations unfold across childhood, vary between cohorts, or differ by ...

Do Genetics Shape Mental Health Trajectories Around Partnership Transitions?

open access: yesJournal of Marriage and Family, EarlyView.
ABSTRACT Objective This study focuses on the extent to which genetic risk for mental disorders contributes to observed mental health problems before and after partnership transitions. Background Partnership formation and dissolution are linked to short‐term changes in mental health, with outcomes varying by gender, socioeconomic position, and other ...

Partial mycoheterotrophy: a common strategy in arbuscular mycorrhizal plants?

open access: yesNew Phytologist, EarlyView.
Proposed autotrophy to mycoheterotrophy continuum among arbuscular mycorrhizal plants. Summary The vast majority of land plants transfer part of the organic carbon they produce by photosynthesis to arbuscular mycorrhizal (AM) fungi inside their root cells; the fungi in turn help plants to take up nutrients and water from the soil.

Nonuniform temperature and light relationships of moss‐associated nitrogen fixation across climates

open access: yesNew Phytologist, EarlyView.
Light, moisture, and temperature response of nitrogen fixation in moss–cyanobacteria associations across five climatically contrasting ecosystems. Responses of nitrogen fixation in moss–cyanobacteria associations to light (μmol photons m−2 s−1), moss relative water content (%), and temperature (°C) across five climatically contrasting ecosystems ...

Assisted Reproductive Technologies and Offspring's School Grades by Maternal Education

open access: yesPaediatric and Perinatal Epidemiology, EarlyView.
ABSTRACT Background Children conceived through assisted reproductive technologies (ART) often achieve higher school grades than spontaneously conceived peers in unadjusted analyses, a pattern largely attributed to the socio‐economic advantage of parents who use ART.
