Passive water control at the surface of a superhydrophobic lichen [PDF]

open access: yes, 2011
Some lichens have a super-hydrophobic upper surface, which repels water drops, keeping the surface dry but probably preventing water uptake. Spore ejection requires water and is most efficient just after rainfall.

Littoral lichens as a novel source of potentially bioactive Actinobacteria

open access: yesScientific Reports, 2015
Cultivable Actinobacteria are the largest source of microbially derived bioactive molecules. The high demand for novel antibiotics highlights the need for exploring novel sources of these bacteria.

Variation in parrot jaw musculature

open access: yesThe Anatomical Record, EarlyView.
Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Photosynthetic performance in Antarctic lichens with different growth forms reflect the diversity of lichenized algal adaptation to microhabitats

open access: yesPolish Polar Research, 2015
Lichens, as typical obligate associations between lichenized fungi and their photosynthetic partners, are dominant in Antarctica. Three Antarctic lichens, Ochrolechia frigida, Umbilicaria antarctica, and Usnea aurantiacoatra with different growth forms ...

Nomenclatural notes on Pseudocyphellaria V : some Brazilian taxa [PDF]

open access: yes, 1993
A new, phyllidiate, white-medulla species with yellow pseudocyphellae and a green photobiont, Pseudocyphellaria kalbii D.J.Galloway, is described from Brazilian collections, and typification and notes on P.

Notes on the amphipacific relations of Hawaiian Cladoniaceae [PDF]

open access: yes, 1993
The total number of currently accepted species of Cladoniaceae in the Hawaiian Islands is 22. Several taxonomic problems still exist, however. The effects of isolation are clear among Cladoniaceae. Endemism is high (c.

Mobilizing mine lands for biobased decarbonization strategies

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Over 163 000 ha of mine lands in Pennsylvania (PA) have the potential to produce willow as a feedstock for renewable energy generation. Each year these lands could produce between 454 000 and 907 000 dry Mg of willow, which can be a feedstock for bioenergy (i.e., biopower) with carbon capture and sequestration (BECCS) or sustainable aviation ...

Review on the toxic effect of fluorine and lead on lichen metabolism

open access: yesInternational Journal of Secondary Metabolite
Thanks to their ability to absorb large amounts of trace elements from the atmosphere, lichens are widely used as bioaccumulators and bioindicators of air pollution.

A lichen protected by a super-hydrophobic and breathable structure [PDF]

open access: yes, 2006
A species of lichen, Lecanora conizaeoides, is shown to be super-hydrophobic. It uses a combination of hydrophobic compounds and multi-layered roughness to shed water effectively.

Insights into the Mechanism of a Vanadium Bromoperoxidase from the Marine Macro‐Algae Corallina pilulifera for Biocatalytic Halogenation

open access: yesChemCatChem, EarlyView.
A study of crystallographic complexes obtained from vanadium haloperoxidase enzymes can determine key amino acids, leucine, and phenylalanine, that change their structural orientation to allow either chloride or bromide to bind to the enzymes active site, thereby determining halide specificity.
