Selective and clear-cut logging have varied imprints on tree community structure in a moist semi-deciduous forest in Ghana

open access: yesHeliyon, 2022
Logging-induced disturbance can be an important agent of change in tropical forests. Understanding the relative impacts of specific logging regimes on tree community structure is essential for forest management and biodiversity conservation.

High Humidity Exacerbates Psoriasiform Skin Disease Relapse by Increasing Tissue‐Resident Memory T Cells via Altering Skin Microbiota

open access: yesAdvanced Science, EarlyView.
We demonstrated that high humidity worsened psoriasis relapse in murine psoriasiform skin inflammation by increasing skin‐resident memory CD8+ cells via upregulating IL‐15Rα on keratinocytes. The increases in IL‐15Rα and memory CD8+ cells were attributed to S. nepalensis and its metabolite ADMA in skin exposed to high humidity.

Investigating LiDAR Metrics for Old-Growth Beech- and Spruce-Dominated Forest Identification in Central Europe

open access: yesRemote Sensing
Old-growth forests are essential for maintaining biodiversity, as they are formed by the complexity of diverse forest structures, such as broad variations in tree height and diameter (DBH) and conditions of living and dead trees, leading to various ...

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

open access: yesAdvanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Smallholder agriculture results in stable forest cover in riverine Amazonia

open access: yesEnvironmental Research Letters, 2021
Recent studies point to a rapid increase in small-scale deforestation in Amazonia. Where people live along the rivers of the basin, customary shifting cultivation creates a zone of secondary forest, orchards and crop fields around communities in what was

Present and prospects for multi-aged silviculture in Chilean temperate forests: Targeting secondary forests in transition and partially harvested old-growth forests

open access: yesFrontiers in Forests and Global Change, 2022
Valdivian Temperate Rainforests in Chile have a global conservation value, but nowadays many correspond to secondary forests following regeneration in agricultural and burned lands, and to high-graded old-growth due to mismanagement, especially at mid to

Adipocyte‐Derived Leptolin Enhances Energy Expenditure and Prevents Obesity

open access: yesAdvanced Science, EarlyView.
We identified a novel adipokine, which we named leptolin. In humans, leptolin levels in white adipose tissue were positively correlated with exercise and negatively associated with body mass index. We observed elevated leptolin in serum from athletes and lower leptolin in serum from obese individuals.

A Rare Allele of ST5 From Wild Rice Enhances Salt Tolerance in Rice

open access: yesAdvanced Science, EarlyView.
A novel salt‐tolerance gene ST5W, characterized by a unique 36‐bp promoter insertion, is found exclusively in a small subset of Oryza rufipogon and is absent in cultivated rice. Field trials confirm ST5W significantly enhances rice yield across diverse genetic backgrounds under saline conditions.

A Brain‐Wide Atlas of Astrocytic Oxytocin Receptors Reveals a Glial Basis for Nucleus Accumbens Modulation of Affiliative Behavior

open access: yesAdvanced Science, EarlyView.
The cellular actors of oxytocin signaling are under intense scrutiny. A brain‐wide anatomical and functional analysis in mice and rats reveals widespread expression of oxytocin receptors in astrocytes. These receptors are functionally active and, in the nucleus accumbens, selectively regulate male social affiliation.

Effects of forest management on native bee biodiversity under the tallest trees in the world

open access: yesEcology and Evolution, 2023
It is not clear if mature secondary growth coniferous forests can support similar pollinator communities as old growth coniferous forests, or how active management (e.g., retention forestry) in mature secondary growth forests may affect pollinator ...
