The Role of Vessel Biofouling in the Translocation of Marine Pathogens: Management Considerations and Challenges

open access: yesFrontiers in Marine Science, 2021
Vessel biofouling is a major pathway for the introduction, establishment, and subsequent spread of marine non-indigenous macro-organisms. As a result, national and international regulations and guidelines have been implemented to manage the risks ...

Linked dimers of the AAA+ ATPase Msp1 reveal energetic demands and mechanistic plasticity for substrate extraction from lipid bilayers

open access: yesFEBS Letters, EarlyView.
Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

CCT4 promotes tunneling nanotube formation

open access: yesFEBS Letters, EarlyView.
Tunneling nanotubes (TNTs) are membranous tunnel‐like structures that transport molecules and organelles between cells. They vary in thickness, and thick nanotubes often contain microtubules in addition to actin fibers. We found that cells expressing monomeric CCT4 generate many thick TNTs with tubulin.

Review of Zethus Fabricius from the West Indies (Hymenoptera: Vespidae) [PDF]

open access: yes, 2003
Eleven species of Zethus are reported for the West Indies including two new species. A re-evaluation of Z. albopictus Smith is accomplished based on new material from Hispaniola leading to the creation of a new species group.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Non-native vascular flora of alpine areas in the White Mountains, New Hampshire, USA

open access: yesArctic, Antarctic, and Alpine Research, 2023
Arctic-alpine vegetation in the eastern United States is unique to northern New England and New York and is disjunct from similar areas in eastern Canada.

Phylogenetic Revision of Eryphanis Boisduval, with a Description of a New Species from Ecuador (Lepidoptera, Nymphalidae) [PDF]

open access: yes, 2008
This study provides a species-level phylogeny for the Neotropical brassoline genus Eryphanis Boisduval based on 43 morphological characters. A revised generic definition is given.

Mitochondrial fatty acid oxidation is stimulated by red light irradiation

open access: yesFEBS Letters, EarlyView.
Light at different wavelengths has distinct effects on keratinocyte viability and metabolism. UVA light abrogates metabolic fluxes. Blue and green light have no effect on metabolic fluxes, while red light enhanced oxidative phosphorylation by promoting fatty acid oxidation. Keratinocytes are the primary constituents of sunlight‐exposed epidermis.

Untangling Community Assembly Through Functional Traits and Phylogenetic Alpha Diversity in Subtropical Karst Forests

open access: yesEcology and Evolution
Taxonomic diversity is insufficient to fully characterize species co‐existence in forest ecosystems. Incorporating trait‐based and phylogenetic data into studies of communities provides insight into the mechanisms by which coexistence emerges and is ...
