Towards bio-inspired polymer adhesives: Activation assisted via HOBt for grafting of dopamine onto poly(acrylic acid)

Erik Alberts, Payagala Fernando, Travis Thornell, Hannah George, Ashlyn M. Koval, Manoj K. Shukla, Charles Weiss & Lee Moores
The design of bio-inspired polymers has long been an area of intense study, however applications to the design of concrete admixtures for improved materials performance have been relatively unexplored. In this work we functionalized poly(acrylic acid) (PAA), a simple analogue to polycarboxylate ether admixtures in concrete, with dopamine to form a catechol-bearing polymer (PAA-g-DA). Synthetic routes utilizing hydroxybenzotriazole (HOBt) as an activating agent were examined for their ability in grafting dopamine to the PAA backbone....

Data from: Birds in space & time: genetic changes accompanying anthropogenic habitat fragmentation in the endangered black-capped vireo (Vireo atricapilla)

Giridhar Athrey, Kelly R. Barr, Richard F. Lance & Paul L. Leberg
Anthropogenic alterations of the natural environment can be a potent evolutionary force. For species that have specific habitat requirements, habitat loss can result in substantial genetic effects, potentially impeding future adaptability and evolution. The endangered black-capped vireo (Vireo atricapilla) suffered a substantial contraction of breeding habitat and population size during much of the 20th century. In a previous study we reported significant differentiation between remnant populations, but failed to recover a strong genetic signal of...

Conspecific attraction for conservation and management of terrestrial breeding birds: current knowledge and future research directions

Jonathon Valente, Christa LeGrande-Rolls, James Rivers, Anna Tucker, Richard Fischer & Matthew Betts
Conspecific presence can indicate the location or quality of resources, and animals settling near conspecifics often gain fitness benefits. This can result in adaptive conspecific attraction during breeding habitat selection as demonstrated in numerous terrestrial, territorial birds. There is growing interest in using simulated conspecific social cues (e.g., decoys, broadcasted vocalizations) to manage bird distributions, yet it remains unclear when this approach is likely to succeed. We reviewed published studies to evaluate whether the strength...
