Stem cambial variants of Taiwan lianas

open access: yesBotanical Studies, 2022
Abstract Background: Cambium in lianas, responsible for secondary growth, develop diverse and diagnostic traits during the climbing phase. Studies on the cross-section of Taiwanese liana cambial variants are scarce. We collected multiple stem cross-sections from 287 liana species belonging to 52 families.

Wanted: new allometric equations for large lianas and African lianas [PDF]

open access: yesBiotropica, 2016
AbstractLiana abundance appears to be increasing, possibly to the detriment of trees, but methods for measuring liana biomass are undependable. We show that five commonly used allometric equations produce disparate results and discuss two large information gaps—Central African lianas and large lianas—that currently preclude accurate liana biomass ...

Increasing dominance of large lianas in Amazonian forests [PDF]

open access: yes, 2002
Ecological orthodoxy suggests that old-growth forests should be close to dynamic equilibrium, but this view has been challenged by recent findings that neotropical forests are accumulating carbon and biomass, possibly in response to the increasing ...

Precipitation and tree biomass correlate with the diversity and functional composition of tropical rainforest cricket assemblages across climate and disturbance gradients

open access: yesEcography, EarlyView.
Disturbance‐driven changes in rainforest structure and environmental conditions can alter ecosystem functioning, yet the consequences for invertebrate communities – key contributors to decomposition, herbivory, and trophic interactions – are not fully understood, particularly in relation to structural changes in vegetation.

Liana cutting for restoring tropical forests : a rare palaeotropical trial [PDF]

open access: yes, 2016
Liana growth following forest disturbance is threatening the tropical carbon sink by delaying or preventing recov ery. Tree growth can be stimulated by liana cutting; however, its applicability for conservation management remains uncertain, particularly ...

Uncovering the role of genetic polymorphisms in cervical insufficiency

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Pathways and genes implicated in CI pathogenesis. Abstract Cervical insufficiency (CI) is characterized by spontaneous dilation of the cervix in the absence of painful uterine contractions in the mid‐trimester, leading to premature delivery. It is responsible for up to 20% of second trimester pregnancy losses, mostly <24 weeks.

First Confirmed Cooperative Breeding of the Brown Hornbill (Anorrhinus austeni) in China at the Sino–Lao Frontier 中国中老边境尚勇保护区首次记录白喉犀鸟 (Anorrhinus austeni) 的合作繁殖行为

open access: yesIntegrative Conservation, EarlyView.
First confirmed breeding of the Brown Hornbill in China, documented through cooperative feeding in Shangyong Protected Area. ABSTRACT The Brown Hornbill (Anorrhinus austeni), a Near Threatened frugivore, reaches the northern edge of its distribution in southern Yunnan, China, yet breeding had not been previously documented with site‐attributed nests in

Discordance of Dopaminergic Dysfunction and Subcortical Atrophy by α‐Synuclein Status in Sporadic and Genetic Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is characterized by predominantly neuronal α‐synuclein pathology and dopaminergic dysfunction. Cerebrospinal fluid (CSF) seeding amplification assays (SAA) detect α‐synuclein aggregates in vivo, but not all patients with PD have a positive SAA.

Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil

open access: yesNordic Journal of Botany, EarlyView.
This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...

Comparing the power of phylogenetic, trait and network structure information to predict plant–frugivore interactions

open access: yesOikos, EarlyView.
Due to the constraints of limited effort and sampling error, observed species interaction networks are an imperfect representation of the ‘true' underlying community. Link prediction methods allow us to construct a potentially more complete representation of a given empirical network by guiding targeted sampling of predicted links, as well as offer ...
