Symbiosis constraints: Strong mycobiont control limits nutrient response in lichens

open access: yesEcology and Evolution, 2017
Symbioses such as lichens are potentially threatened by drastic environmental changes. We used the lichen Peltigera aphthosa—a symbiosis between a fungus (mycobiont), a green alga (Coccomyxa sp.), and N2‐fixing cyanobacteria (Nostoc sp.)—as a model ...

Southern mountain caribou are a federally designated species at risk, with declines occurring throughout their range. This species overlaps spatially and temporally in their late‐winter habitats with heli‐skiing, an activity that relies on helicopters to transport skiers to remote mountainous locales.

Malignant Transformation Rate of Oral Premalignant Disorders: A Large Database Analysis

open access: yesThe Laryngoscope, EarlyView.
ABSTRACT Objectives Oral leukoplakia (OL), oral lichen planus (OLP), and oral submucous fibrosis (OSF) are precancerous lesions known to progress to oral squamous cell carcinoma (OSCC). The transformation rates to OSCC are controversial and have been based on small, heterogeneous, single‐institution studies. We present the largest study to date looking

Origin and characterization of cyclodepsipeptides: Comprehensive structural approaches with focus on mass spectrometry analysis of alkali‐cationized molecular species

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Cyclodepsipeptides (CDPs) represent a huge family of chemically and structurally diverse molecules with a wide ability for molecular interactions. CDPs are cyclic peptide‐related natural products made up of both proteinogenic and nonproteinogenic amino acids linked by amide and ester bonds.

Effects of boreal ground layer shrubs and bryophytes on the diversity, biomass and composition of lichen communities across contrasting ecosystems

open access: yesOikos, EarlyView.
There has been much recent interest in understanding how abiotic factors such as light, nutrients, and soil moisture affect the composition and biomass of lichen communities. Meanwhile, whether and how ground layer vegetation such as bryophytes and shrubs also influence lichen communities have received much less attention, particularly regarding how ...
