Untying the Gordian knot of plastid phylogenomic conflict: A case from ferns

open access: yesFrontiers in Plant Science, 2022
Phylogenomic studies based on plastid genome have resolved recalcitrant relationships among various plants, yet the phylogeny of Dennstaedtiaceae at the level of family and genera remains unresolved due to conflicting plastid genes, limited molecular ...

More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]

open access: yes, 2013
The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Charting the Evolution of Open Data Business Models: Insights From a Systematic Review and Thematic Analysis of a Decade

open access: yesStrategic Change, EarlyView.
ABSTRACT This article presents a decade of research on Open Data Business Models (ODBM), aiming to identify conceptual gaps, categorize thematic trends, and propose an integrative framework. This paper, based on a systematic literature review (SLR) of 60 peer‐reviewed studies, develops a coherent framework that explains how ODBMs are formed, adapted ...

The Effects of Hydro-alcoholic Extracts of Allium sativum L. and Orchismaculata L. on Spermatogenesis Index and Testosterone Level in Cyclophosphamide-treated Rats [PDF]

open access: yesJournal of Kerman University of Medical Sciences, 2020
Background:One of the most common side effects of cyclophosphamide (CP) is oligo-spermatozoa, azoospermia and elimination of spermatogenic cycles. This study was done to find the efficacy of simultaneous consumption of garlic (Allium sativum L.) and ...

Definition of a sensory lexicon and development of sensory wheels of eighteen monovarietal Italian white wines

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Italy harbors one of the richest grapevine biodiversities worldwide, yet the sensory identity of wines from many native cultivars remains poorly defined despite their relevance on the market at regional, national, or international levels.

Differences in reproductive performance traits of two Platanthera species

open access: yesNordic Journal of Botany, EarlyView.
The species Platanthera bifolia and P. chlorantha (Orchidaceae) are both declining in Europe, but P. bifolia has been diminishing relatively more. Loss of habitats and landscape heterogeneity due to agricultural intensification or abandonment of less fertile areas are primary drivers of decreasing orchid populations.

Whole Genome Duplication Events Likely Contributed to the Aquatic Adaptive Evolution of Parkerioideae

open access: yesPlants
As the only aquatic lineage of Pteridaceae, Parkerioideae is distinct from many xeric-adapted species of the family and consists of the freshwater Ceratopteris species and the only mangrove ferns from the genus Acrostichum.

Analysis of Comparative Transcriptome and Positively Selected Genes Reveal Adaptive Evolution in Leaf-Less and Root-Less Whisk Ferns

open access: yesPlants, 2022
While roots and leaves have evolved independently in lycophytes, ferns and seed plants, there is still confusion regarding the morphological evolution of ferns, especially in whisk ferns, which lack true leaves and roots and instead only exhibit leaf ...
