Forest health, heart rot disease, and their impact on the source of carbon‐based greenhouse gas fluxes

open access: yesNew Phytologist, Volume 250, Issue 2, Page 921-933, April 2026.
Summary Forest health is critical for sustaining ecosystem services like carbon sequestration. Heart rot, a widespread disease in upland northern hardwood forests, may affect greenhouse gas (CO2 and CH4) fluxes, but its impacts remain poorly measured. Using non‐destructive tomography and direct gas flux measurements, we quantified the effects of heart ...

Secrets within stems: The cryptic Apodanthes caseariae (Apodanthaceae), a rare neotropical holoendoparasite

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 385-400, March 2026.
Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.

Alterations of the giant pyramidal neurons (Betz cells) in brain cortex of rat offspring born from gestational diabetic dams: A morphometric study [Alteraciones de las Neuronas Piramidales Gigantes de la Corteza Cerebral en Crías de Ratas Nacidas de Hembras con Diabetes Gestacional: Un Estudio Morfométrico] [PDF]

open access: yes, 2015
A few studies reported the adverse effects of gestational diabetes on hippocampus and spinal cord of rat offspring. Giant pyramidal neurons are giant pyramidal neurons located in fifth layers of the gray matter in the primary motor cortex.

Investigating plant awareness: Image composition affects student perceptions of flora and fauna

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 611-625, March 2026.
This study investigates the effect of the positoning of plants and animals in landscape photographs on their perception by students and the detail with which they get described. We conclude that the positioning of plants, among other factors, significantly influences how strongly they are perceived.

Towards an evidence‐based and research‐driven restoration strategy for Britain's temperate rainforests

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 411-421, March 2026.
Woodlands globally are threatened by environmental change and biodiversity loss. Temperate rainforests are an ecologically rich ecosystem found in wet regions of the temperate zone, and Britain has the potential for major temperate rainforest coverage in its nature‐depleted landscape.

Potential drivers of fast growth in Paulownia

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 516-529, March 2026.
Trees in the genus Paulownia play a crucial role in sustainable forestry, rural economic development, and carbon mitigation due to their rapid growth, exceptional hardwood properties, and prominent carbon sequestration capacity. This review highlights the societal value of Paulownia trees and synthesizes several potential drivers of extraordinarily ...
